ITEM 1.  BUSINESS.

General
------------------------------------------------------------------------------

    Duquesne Light Company (Duquesne) is a wholly owned subsidiary of DQE, an
energy services holding company formed in 1989.  Duquesne is engaged in the
production, transmission, distribution and sale of electric energy.  Duquesne
was formed under the laws of Pennsylvania by the consolidation and merger in
1912 of three constituent companies.


Service Territory

    Duquesne provides electric service to customers in Allegheny County,
including the City of Pittsburgh, and Beaver County.  This represents a service
territory of approximately 800 square miles.  The population of the area served
by Duquesne, based on 1990 census data, is approximately 1,510,000, of whom
370,000 reside in the City of Pittsburgh.  In addition to serving approximately
580,000 customers within this service area, Duquesne also sells electricity to
other utilities beyond its service territory.


Regulation

    Duquesne's operations are subject to regulation by the Pennsylvania Public
Utility Commission (PUC).  Duquesne is also subject to regulation by the Federal
Energy Regulatory Commission (FERC) under the Federal Power Act in respect of
rates for interstate sales, transmission of electric power, accounting and other
matters.

    Duquesne is subject to regulation by the Nuclear Regulatory Commission (NRC)
under the Atomic Energy Act of 1954, as amended, with respect to the operation
of its jointly owned/leased nuclear power plants, Beaver Valley Unit 1, Beaver
Valley Unit 2 and Perry Unit 1.

    Duquesne is subject to the accounting and reporting requirements of the
Securities and Exchange Commission.  As a result, Duquesne's consolidated
financial statements contain regulatory assets and liabilities in accordance
with Statement of Financial Accounting Standards No. 71, Accounting For the
Effects of Certain Types of Regulation (SFAS No. 71) and reflect the effects of
the ratemaking process.  In accordance with SFASNo. 71, Duquesne's financial
statements reflect regulatory assets and costs based on current cost-based
ratemaking regulations.  The regulatory assets represent probable future revenue
to Duquesne because provisions for these costs are currently included, or are
expected to be included, in charges to utility customers through the ratemaking
process.

    Duquesne's operations currently satisfy the SFAS No. 71 criteria.  However,
Duquesne's operations, or a portion thereof, could cease to meet these criteria
for various reasons, including a change in PUC or FERC regulations.  In such an
event, Duquesne would be required to write-off any regulatory assets or
liabilities for those operations that no longer meet the SFAS No. 71
requirements.

Seasonality

    Sales of electricity to ultimate customers by Duquesne tend to increase
during the warmer summer and cooler winter seasons because of greater customer
use of electricity for cooling and heating.

1993        2994             2762             3279             2816

    The overall level of business activity in Duquesne's service territory and
weather conditions are expected to continue to be the primary factors affecting
sales of electricity to ultimate customers in the near term.  Duquesne's
electric sales may also be affected in the long-term by increased competition in
the electric utility industry.  (See "Competition" discussion on page 12.)

Sales of Electricity to Customers

    Customer operating revenues result from Duquesne's sales of electricity to
ultimate customers and are based on rates authorized by the PUC.  These rates
are cost-based and are designed to recover Duquesne's energy and other operating
expenses and investment in utility assets and to provide a return on the
investment.  In 1994, sales to Duquesne's 20 largest customers accounted for
14.6 percent of customer revenues.  Sales to USX Corporation, Duquesne's largest
customer, accounted for 3.8 percent of total 1994 customer revenues.  Total
kilowatt-hour (KWH) sales to ultimate customers in 1994 increased 2.3 percent in

                                       2
<PAGE>
 
comparison with KWH sales to ultimate customers in 1993.  Commercial and
industrial KWH sales increased 1.3 percent and 6.9 percent, respectively,
benefiting from the improving economy and a slight growth in the numbers of
customers.  Industrial sales volume also increased as a result of Duquesne's
marketing efforts and fewer customer production facility outages.  Compared to
1994 and 1992, the significantly hotter summer in 1993 resulted in higher
residential KWH sales volume.


Phase-in Deferrals

    Phase-in deferred revenues represent the deferral and subsequent recovery of
revenues resulting from a $232 million rate increase granted in early 1988.  The
PUC required Duquesne to phase this increase in during a six-year period, which
ended in April 1994.


Sales to Other Utilities

    Short-term power sales to other utilities in 1994, 1993 and 1992 were
3,212,110 KWH, 2,820,920 KWH and 4,059,989 KWH, respectively.  Fluctuations in
electricity sales to other utilities are related to Duquesne's customer energy
requirements, the energy market and transmission conditions and the availability
of Duquesne's generating stations.  Short-term sales to other utilities are
regulated by FERC and are made at market rates.  Revenues from sales to other
utilities were $58.3 million, $50.7 million and $72.4 million in 1994, 1993 and
1992, respectively.  Because of reduced generating station availability,
Duquesne had fewer off-system sales in 1993 than in 1994 or 1992.  Future levels
of off-system sales of electricity will be affected by the outcome of Duquesne's
FERC filings requesting firm transmission access.  (See "Transmission Access"
discussion on page 13.)

    Generally, Duquesne is permitted to recover (to the extent that such amounts
are not included in base rates) fuel and other energy costs from its customers
through an energy cost rate adjustment clause (ECR), subject toPUC review.  This
revenue adjustment includes a credit to Duquesne's customers for profits from
short-term sales to other utilities.  The credit to Duquesne's customers for
profits from short-term sales to other utilities was $16.6 million in 1994,
$12.1 million in 1993 and $19.1 million in 1992.  (See "Energy Cost Rate
Adjustment Clause" discussion on page 6.)


Operating Expenses

    Fuel and purchased power expense fluctuations result from changes in the
cost of fuel, the mix between coal and nuclear generation, the total KWHs sold
and generating station availability.  Because of the ECR, changes in fuel and
purchased power cost normally do not impact earnings.

==========================================================================================
</TABLE>

  The average unit cost of coal declined slightly in 1994, after remaining
relatively constant during 1993. Meanwhile, the average unit cost of nuclear
fuel has declined continually during the past three years.

  Generation mix impacts fuel expense as Duquesne's nuclear fuel cost per KWH is
less than its fossil fuel cost per KWH.  During 1993, compared to 1994 and 1992,
Duquesne had more scheduled nuclear station refueling outages, resulting in less
nuclear generation and more fuel expense.

                                       3
<PAGE>
 
  Generation volume during 1994 increased 3.4 percent compared to 1993 due to
fewer generating station outages.  During 1993, generation decreased 5.6 percent
from 1992.

  Purchased power volume increased in 1994 compared to 1993 because of the
timing of generating station outages.  Purchased power volume increased in 1993
compared to 1992 primarily due to the performance of the Perry plant. (See
"Perry Unit 1" on page 8.)

  Maintenance expense fluctuations primarily result from the timing of scheduled
generating station outages, the timing of scheduled transmission and
distribution line maintenance and the effect of storms on overhead lines and
transformers.  Incremental maintenance expense incurred for scheduled refueling
outages at Duquesne's nuclear units is deferred for amortization over the period
(generally 18 months) between scheduled outages.  During 1994 and 1993,
amortization of deferred nuclear refueling outage expense increased, reflecting
the higher costs of more recent refueling outages.  Offsetting this increase in
1994 was a decrease in transmission and distribution line maintenance expense.
Also increasing maintenance expense in 1993 was Duquesne's change, as of January
1, 1993, in its method of accounting for maintenance costs during major fossil
generating station outages.  Prior to 1993, maintenance costs incurred for
scheduled major outages at fossil generating stations were charged to expense as
the costs were incurred.  Under the new accounting policy, Duquesne accrues,
over the period between outages, anticipated expenses for scheduled major fossil
station outages.  (Maintenance costs incurred for non-major scheduled outages
and for forced outages continue to be charged to expense as the costs are
incurred.)  This method was adopted to match more accurately the maintenance
costs with the revenue produced during the periods between scheduled major
fossil generating station outages.

  Depreciation and amortization expense includes, in addition to depreciation of
plant and equipment, nuclear decommissioning accruals, amortization of
regulatory tax receivables and amortization of an extraordinary property loss.
Depreciation and amortization expense increased $6.4 million in 1994, compared
to the prior year due to increases in depreciable property and nuclear
decommissioning expense.  The 1993 increase results from amortization of
regulatory tax receivables which began January 1, 1993, concurrent with the
adoption of Statement of Financial Accounting Standards No. 109 (SFAS No. 109).
During 1994, Duquesne completed an extensive review of its depreciation rates
and submitted an informational filing to thePUC.  As a result of this study,
beginning in 1995 Duquesne's composite depreciation rate increased from 3.0
percent to 3.5 percent.  It is anticipated that annual depreciation expense will
increase by approximately $25 million in 1995 compared to the 1994 level.
Duquesne is not currently seeking a rate increase to recover these additional
costs.

  During 1994, the statutory Pennsylvania income tax rate was reduced from 12.25
percent to 9.99 percent; this reduction is to be phased in over four years.
This change resulted in a net decrease of $87.2 million in deferred tax
liabilities and a corresponding reduction recorded as a tax rate adjustment -
regulatory tax receivable.

  Taxes other than income taxes were lower in 1993 compared to 1994 and 1992,
primarily as a result of a favorable resolution of certain property tax
assessments.  In 1993, Duquesne recorded, on the basis of these revised
assessments, the expected refunds for overpayments in prior years.


Other Income and Deductions

  Consistent with the conclusion of Duquesne's revenue phase-in plan, other
income decreased in 1994, in comparison with that for 1993 and 1992, as a result
of a decrease in carrying charges on deferred revenues.

  Income taxes related to other income increased $12.5 million in 1994, in
comparison with those for 1993, because in 1993 Duquesne obtained a favorable
settlement (related to Duquesne's 1988 tax return and the consolidated 1989 tax
return) with the Internal Revenue Service.

Construction
-------------------------------------------------------------------------------

    During 1994, Duquesne spent approximately $94.3 million for construction.
Duquesne expended these amounts to improve and/or expand its production,
transmission and distribution systems.  Construction programs of Duquesne focus
on the need to serve new customers, to provide for the replacement of utility
property and to modify facilities consistent with the most current environmental
and safety regulations.  Duquesne estimates that it will spend approximately $80
million for construction annually in 1995, 1996 and 1997.  These amounts exclude
AFC, nuclear fuel, expenditures for possible early replacement of steam
generators at the Beaver Valley Power Station and expenditures for the
refurbishment of the cold-reserved units.  (See Notes F and L to Duquesne's
consolidated financial statements.)  Duquesne currently has no plans for
construction of new base load generating plants and expects that funds generated
from operations will continue to be sufficient to finance a large part of its
capital needs.


Capital Resources and Liquidity
-------------------------------------------------------------------------------

Financing

    Duquesne plans to meet its current obligations and debt maturities through
1999 with funds generated from operations and through new financings.  At
December 31, 1994, Duquesne was in compliance with all of its debt covenants.

    During 1993, Duquesne refinanced $734.2 million of long-term debt.  In 1994,
Duquesne continued to reduce its cost of capital by refinancing and retiring
securities.

    During 1994, all of the outstanding shares of $2.10 and $7.50 preference
stock were redeemed for approximately $37.7 million.  Duquesne also retired $2.2
million of $7.20 preferred stock.  InMay 1994, Duquesne filed a shelf
registration statement for the issuance of up to $150 million of Duquesne
CapitalL.P. Cumulative Monthly Income Preferred Securities.  These preferred
securities have not been issued.

    During 1994, Duquesne also issued $114.1 million of its pollution control
obligations to replace a like amount of higher cost pollution control
obligations.  The new pollution control obligations bear variable interest rates
and mature October 1, 2029.


Short-Term Borrowings

    Duquesne has an extendible revolving credit agreement with a group of banks
totaling $150 million.  The current expiration date of this credit arrangement
is October 6, 1995.  Interest rates can, in accordance with the option selected
at the time of each borrowing, be based on prime, Eurodollar or certificate of
deposit rates. Commitment fees are based on the unborrowed amount of the
commitments.  The arrangement contains a two-year repayment period for any
amounts outstanding at the expiration of the revolving credit period.

    During 1994 and 1993, the maximum short-term bank and commercial paper
borrowings outstanding were $25.6 million and $27 million; the average daily
short-term borrowings outstanding were $1.9 million and $1.6 million; and the
weighted average daily interest rates applied to such borrowings were 5.23
percent and 3.42 percent, respectively.  At December 31, 1994, there were no
short-term borrowings.  Short-term borrowings at December 31, 1993, were $11.0
million.


Interest Charges

    Duquesne achieved a $9.1 million reduction in interest charges in 1994
through refinancing first mortgage bonds and certain tax exempt pollution
control notes. Duquesne also retired $39.9 million of preferred and preference
stock during 1994.  Interest expense and dividends on preferred and preference
stock

                                       5
<PAGE>
 
declined to $108 million in 1994 from $121 million in 1993 and $135 million in
1992.  Interest expense is expected to continue to decline in 1995.


Sale of Accounts Receivable

    Duquesne and an unaffiliated corporation have an agreement that entitles
Duquesne to sell and the corporation to purchase, on an ongoing basis, up to $50
million of accounts receivable.  Duquesne had no receivables sold at December
31, 1994.  The accounts receivable sales agreement, which expires in June 1995,
is one of many sources of funds available to Duquesne.  Upon expiration of this
facility, Duquesne expects to extend the agreement or to replace the facility
with a similar one.


Nuclear Fuel Leasing

    Duquesne Finances its acquisitions of nuclear fuel through a leasing
arrangement under which it may finance up to $75 million of nuclear fuel.  As of
December 31, 1994, the amount of nuclear fuel financed by Duquesne under this
arrangement totaled approximately $52 million.  Duquesne plans to continue
leasing nuclear fuel to fulfill its requirements at least through September
1996, the remaining term of the leasing arrangement.


Rate Matters
-------------------------------------------------------------------------------

    Electric rates charged by Duquesne to its customers are regulated by the
PUC.  Electric rates charged to the Borough of Pitcairn and to other electric
utilities are regulated by the FERC.  These rates are designed to recover
Duquesne's operating expenses, investment in utility assets, and a return on
those investments.  Sales to other utilities are made at market rates.  (See
Note F to Duquesne's consolidated financial statements for additional discussion
of rate-related matters.)  At this time, Duquesne has no pending base rate case
and has no immediate plans to file a base rate case.


Energy Cost Rate Adjustment Clause (ECR)

    Through the ECR, Duquesne recovers (to the extent that such amounts are not
included in base rates) nuclear fuel, fossil fuel and purchased power expenses
and, also through the ECR, passes to its customers the profits from short-term
power sales to other utilities (collectively, ECR energy costs).  Nuclear fuel
expense is recorded on the basis of the quantity of electric energy generated
and includes such costs as the fee, imposed by the United States Department of
Energy (DOE), for future disposal and ultimate storage and disposition of spent
nuclear fuel.  Fossil fuel expense includes the costs of coal and fuel oil used
in the generation of electricity.

    On Duquesne's statement of consolidated income, these energy cost recovery
revenues are included as a component of operating revenues.  For ECR purposes,
Duquesne defers fuel and other energy expenses for recovery, or refunding, in
subsequent years.  The deferrals reflect the difference between the amount that
Duquesne is currently collecting from customers and its actual ECR energy costs.
ThePUC annually reviews Duquesne's ECR energy costs for the fiscal year April
through March, compares them to previously projected ECR energy costs and
adjusts the ECRfor over- or under-recoveries and for two PUC-established coal
cost standards. (See Notes A and F to Duquesne's consolidated financial
statements.)

    Over- or under-recoveries from customers are recorded as payable to, or
receivable from, customers. At December 31, 1994, $5.9 million was receivable
from customers and shown as other current assets.  At December 31, 1993, $10.1
million was payable to customers and shown as deferred energy costs.

                                       6

Deferred Rate Synchronization Costs

    In 1987, the PUC approved Duquesne's petition to defer initial operating and
other costs of Perry Unit 1 and Beaver Valley Unit 2. Duquesne deferred the
costs incurred from November 17, 1987, when the units went into commercial
operation, until March 25, 1988, when a rate order was issued. In its order, the
PUC postponed ruling on whether these costs would be recoverable from
ratepayers.  At December 31, 1994, these costs totaled $51.1 million, net of
deferred fuel savings related to the two units.  Duquesne is not earning a
return on the deferred costs.  Duquesne believes that these costs are
recoverable. In 1990, the PUC permitted another Pennsylvania utility to recover
such costs.


Generating Units
-------------------------------------------------------------------------------

Joint Interests

    Duquesne has various contracts with The Potomac Edison Company, Monongahela
Power Company, Ohio Edison Company, Pennsylvania Power Company, The Cleveland
Electric Illuminating Company (CEI) and The Toledo Edison Company including
provisions for coordinated maintenance responsibilities, limited and qualified
mutual back-up in the event of outages and certain capacity and energy
transactions.

    Duquesne has an interest in the following nuclear plants jointly with the
following companies:

(1) In 1987, Duquesne sold and leased back its 13.74 percent interest in Beaver
Valley Unit 2; the sale was exclusive of transmission and common facilities.
The total sales price of $537.9 million was the appraised value of Duquesne's
interest in the property.  Duquesne subsequently leased back its interest in the
unit for a term of 29.5 years.  The lease provides for semiannual payments and
is accounted for as an operating lease.  Duquesne is responsible under the terms
of the lease for all costs of its interest in the unit.  (See Note C to
Duquesne's consolidated financial statements.)

    Duquesne has an interest in the following fossil plants jointly with the

    Under the agreements governing the operation of these jointly owned
generating units, the day-to-day operating authority is assigned to a specific
company.  CEI has such authority for Perry Unit 1 and Eastlake Unit 5, Ohio

Duquesne monitors activities in connection with all of these units.  Duquesne
has day-to-day operating authority for Beaver Valley Units 1 and 2.  All the
companies with a joint interest in these units are kept fully informed of
developments at these generating units.


Beaver Valley Power Station

    In 1994, the Beaver Valley Power Station achieved the highest combined
(Units 1 and 2) capacity factor (87.7%) in the history of the station.  Capacity
factor is a key production measure.  It is the ratio of the power actually
generated by a facility to the facility's rated capacity during that period of
time.  It is also a key indicator of how well the stations are operated based on
their design capabilities.


Perry Unit 1

    Duquesne has a 13.74 percent ownership interest in Perry Unit 1, a nuclear
generating unit located in Ohio and operated by CEI.  During 1993, Perry Unit 1
had an equivalent availability factor of 39 percent.  This performance resulted
from several outages.  As a result of the length of these outages, the PUC
imposed a penalty for increased incremental replacement power costs.  The 1994
equivalent availability factor was 44 percent.  This performance resulted from
an extended outage (190 days) for refueling and maintenance.  From the end of
the outage in August 1994, through the balance of 1994, Perry operated at full
capacity except for short durations of reduced power for testing and minor on-
line maintenance activities.

    CEI previously submitted to the Nuclear Regulatory Commission an action
plan, called the Perry Course of Action (PCA), designed by CEI to "correct
identified management, technical, and programmatic deficiencies" at the plant
over roughly a three-year period, and to"correct the downward trending
performance" of Perry.  CEImanagement represents to Duquesne that the PCA is on
schedule and will be an effective program to ensure that Perry is in conformance
with industry standards for boiling water reactors.  Based on actual costs and
estimates obtained from CEI, the total costs to bring the plant into compliance,
including the costs associated with implementing the PCA, are more than the cost
originally projected by CEI.  Duquesne cannot predict the ultimate cost, timing
or effectiveness of the PCA, and is continuing to closely monitor the situation.


Property Held for Future Use

    In 1986, the PUC approved Duquesne's request to remove the Phillips and most
of the Brunot Island (BI) power stations from service and place them in cold
reserve.  Duquesne expects to recover its net investment in these plants through
future electricity sales.  Phillips and BI represent licensed, certified, clean
sources of electricity that will be necessary to meet expanding opportunities in
the power markets.  Duquesne believes that anticipated growth in peak demand for
electricity within its service territory will require additional peaking
generation.  Duquesne looks to BI to meet this need.  The Phillips power plant
is an important component in Duquesne's strategy to identify and serve
opportunities for providing bulk power service.  With recent legislation
promoting wider transmission access to bulk power markets and with the
opportunity to package a sale of power from Phillips with the support of
Duquesne's system, the Phillips plant could be made a highly reliable, cost-
competitive alternative for most purchasers.  In summary, Duquesne believes its
investment in these cold-reserved plants will be necessary in order to meet
future business needs.  If business opportunities do not develop as expected,
Duquesne will consider the sale of these assets.  In the event that market
demand, transmission access or rate recovery do not support the utilization or
sale of the plants, Duquesne may have to write off part or all of their costs.
At December 31, 1994, Duquesne's net investment in thePhillips and BI power
plants was $93.0 million and $42.0 million, respectively.


Employees
-------------------------------------------------------------------------------

    At December 31, 1994, Duquesne had 3,754 employees, including 1,231
employees at the Duquesne-operated Beaver Valley Power Station.  The
International Brotherhood of Electrical Workers represents 2,262 of Duquesne's
employees.  The current collective bargaining agreement expires September 30,
1998.

Electric Utility Operations
-------------------------------------------------------------------------------

    Approximately 73 percent of the electric energy generated by Duquesne's
system during 1994 was produced by its coal-fired generating capacity and
approximately 27 percent by its nuclear generating capacity.  Duquesne normally
experiences its peak loads in the summer.  The 1994 customer system peak, the
highest system peak in Duquesne's history, of 2,535 megawatts occurred on June
16, 1994.

    Duquesne's fossil plants operated at 85 percent availability in 1994 and 83
percent in 1993.  Duquesne's nuclear plants operated at 75 percent availability
in 1994 compared to 63 percent in 1993.  The timing of scheduled maintenance and
refueling outages, as well as the duration of forced outages, affect
availability of power plants.

    The North American Electric Reliability Council, of which Duquesne is a
member, uses capacity margin to report generating capability as compared to
demand.  Capacity margin is expressed as capacity less demand divided by
capacity.  Although Duquesne also uses criteria other than capacity margin for
determining the need for installation of additional generating capability,
Duquesne's capacity margin in 1994 was 9.4 percent based on installed non-cold-
reserved generating capacity and internal peak load, including 93 megawatts of
interruptible load.  Duquesne has ties with regional utilities which provide the
capability to import in excess of 4,000 megawatts of capacity to supplement
Duquesne's generation, as required.

    Additional information relating to Duquesne's electric operations is set
forth on page 44 of DQE's Annual Report to Shareholders for the year ended
December 31, 1994.  The information is incorporated here by reference.


Fossil Fuel
-------------------------------------------------------------------------------

    Duquesne believes that sufficient coal for its coal-fired generating units
will be available from various sources to satisfy its requirements for the
foreseeable future.  During 1994, approximately 2.6 million tons of coal were
consumed at Duquesne's two wholly owned coal-fired stations - Cheswick and
Elrama.

    Duquesne owns Warwick Mine, an underground mine located on the Monongahela
River approximately 83 river miles from Pittsburgh. Warwick Mine has been
excluded from rate base since 1981. Duquesne temporarily idled the mine in June
1988 due to excess coal inventories. In 1990, Duquesne restarted the mine by an
agreement under which an unaffiliated company operates the mine until March 2000
and sells the coal produced. Production began in late 1990. The mine produced
1.1 million tons of coal in 1994. Warwick Mine coal reserves include both high
and low sulfur coal; the sulfur content averages in the mid-range at 1.7
percent -- 1.9 percent. More than 60 percent of the coal mined at Warwick Mine
currently is used by Duquesne. Duquesne receives a royalty on any sales of
coal to the open market. The Warwick Mine currently supplies less than
one-fifth of the coal used in the production of electricity at the plants
owned or jointly owned by Duquesne. Duquesne estimates that, at December 31,
1994, its economically recoverable coal reserves at Warwick Mine were 10.4
million tons. Costs at Warwick Mine and Duquesne's investment in the mine are
expected to be recovered through the cost of coal in the ECR. Recovery is
subject to the system-wide coal cost standard. Duquesne also has an
opportunity to earn a return on its investment in the mine through the cost of
coal during the period of the system-wide coal cost standard, including
extensions. At December 31, 1994, Duquesne's net investment in the mine was
$18.9 million. The estimated current liability, including final site
reclamation, mine water treatment and certain labor liabilities for mine
closing is $33.0 million and Duquesne has recorded a liability in the
consolidated balance sheet of approximately $12.8 million
toward these costs. (See Note F of Duquesne's consolidated financial statements
for a discussion of Duquesne's investment in Warwick Mine costs.)

    During 1994, 56 percent of Duquesne's coal supplies were provided by
contracts, with the remainder satisfied through purchases on the spot market.
Duquesne had four long-term contracts in effect at December 31, 1994, which, in
combination with spot market purchases, are expected to furnish an adequate
future coal supply.  Duquesne does not anticipate any difficulty in replacing or
renewing these contracts as they expire in

                                       9
<PAGE>
 
future years ranging from 1995 through 2002.  At December 31, 1994, Duquesne's
wholly owned and jointly owned generating units had on hand an average coal
supply of 51 days.

    The PUC has established two market price coal cost standards.  One applies
only to coal delivered at the Mansfield plant.  The other, the system-wide coal
cost standard, applies to coal delivered to the remainder of Duquesne's system.
Both standards are updated monthly to reflect prevailing market prices of
similar coal during the month.  The PUC has directed Duquesne to defer recovery
of the delivered cost of coal to the extent that such cost exceeds generally
prevailing market prices for similar coal, as determined by the PUC.  The PUC
allows deferred amounts to be recovered from customers when the delivered costs
of coal fall below such PUC-determined prevailing market prices.

    The system-wide coal cost standard may be extended by Duquesne through March
2000. The unrecovered cost of Mansfield coal was $7.3 million and the
unrecovered cost of the remainder of the system-wide coal was $3.4 million at
December 31, 1994. Duquesne estimates that all deferred coal costs will be
recovered. Duquesne's average cost per ton of coal consumed, including the cost
of delivery, during the past three years at generating units which it operates
or in which it has an ownership interest was as follows: 1994-$39.12; 1993-
$40.08 and 1992-$40.44. (See Note F to Duquesne's consolidated financial
statements for a discussion of the coal cost standards.) The cost of coal, which
falls within the market price limitations discussed in Note A of Duquesne's
consolidated financial statements, is recovered from Duquesne's customers
through the ECR discussed previously in "Rate Matters" on page 6.


Nuclear Fuel
-------------------------------------------------------------------------------

    The cycle of production and utilization of nuclear fuel consists of (1)
mining and milling of uranium ore and processing the ore into uranium
concentrates, (2) conversion of uranium concentrates to uranium hexafluoride,
(3) enrichment of the uranium hexafluoride, (4) fabrication of fuel assemblies,
(5) utilization of the nuclear fuel in the generating station reactor and (6)
storing and disposal of spent fuel.

    Adequate supplies of uranium and conversion services are under contract for
Duquesne's requirements for its jointly owned/leased nuclear units through 1997.
Enrichment services are supplied under a 1984 United States Enrichment
Corporation Utility Services Contract entered into for a period of 30 years by
the companies for their joint interests in Perry Unit 1 and Beaver Valley Units
1 and 2.  Under the terms of this contract Duquesne is committed to 100 percent
of its enrichment needs through 1998 and 70 percent in 1999.  Fuel fabrication
contracts are in place to supply reload requirements for the next two cycles for
Beaver Valley Unit 1, the next two cycles for Beaver Valley Unit 2 and the next
twenty cycles of Perry Unit 1.  Duquesne will be required to make arrangements
for uranium supply and related services as existing commitments expire.

    For joint interests in generating units (See "Generating Units" discussion
on page 7.), each company is responsible for financing its proportionate share
of the costs of nuclear fuel for each nuclear unit in which it has an ownership
interest.  Duquesne has entered into a lease arrangement for the acquisition of
nuclear fuel pursuant to which Duquesne is permitted to finance up to $75
million.  As of December 31, 1994, the cost of Duquesne's nuclear fuel financed
was $52 million.  Duquesne's nuclear fuel costs, which are amortized to reflect
fuel consumed, are charged to fuel expense and are recovered through rates.
Duquesne estimates that, over the next three years, the amortization of nuclear
fuel consumed will exceed the expenditures for new fuel by approximately $13
million.  The actual nuclear fuel costs to be financed and amortized during the
period 1995 through 1997 will be influenced by such factors as changes in
interest rates, lengths of the respective fuel cycles and changes in nuclear
material cost and services, the prices and availability of which are not known
at this time.  Such costs may also be influenced by other events not presently
foreseen.

    Duquesne's nuclear fuel costs related to Beaver Valley Unit 1, Beaver Valley
Unit 2 and Perry Unit 1 under the lease arrangement are charged to fuel expense
based on the quantity of energy generated. Nuclear fuel costs for these units
averaged .903, .918 and .975 cents per KWH in 1994, 1993 and 1992, inclusive of
charges associated with spent fuel, respectively. Duquesne is recovering from
its customers the costs associated with the ultimate disposal of spent fuel.

Nuclear Decommissioning
-------------------------------------------------------------------------------

    The PUCruled that recovery of the decommissioning costs for Beaver Valley
Unit 1 could begin in 1977, and that recovery for Beaver Valley Unit 2 and Perry
Unit 1 could begin in 1988.  Duquesne expects to decommission Beaver Valley Unit
2 and Perry Unit 1 following the end of their operating lives, a date that
currently coincides with the expiration of each plant's operating license.  Upon
expiration of the Beaver Valley Unit 1 operating license, the unit will be
placed in safe storage until the expiration of the Beaver Valley Unit 2
operating license, at which time the units may be decommissioned together.

    Based upon site specific studies finalized in 1992 for Beaver Valley Unit 2,
and in 1994 for Beaver Valley Unit 1 and Perry Unit 1, Duquesne's share of the
total estimated decommissioning costs, including removal and decontamination
costs, currently being used to determine Duquesne's cost of service, are $122
million for Beaver Valley Unit 1, $35 million for Beaver Valley Unit 2, and $67
million for Perry Unit 1.

    In conjunction with an August 18, 1994 PUC Accounting Order, Duquesne has
increased the annual contribution to its decommissioning trusts by $2 million to
bring the total annual funding to approximately $4 million per year.  Duquesne
plans to continue making periodic reevaluations of estimated decommissioning
costs, to provide additional funding from time to time, and to seek regulatory
approval for recognition of these increased funding levels.


Environmental Matters
-------------------------------------------------------------------------------

    The Comprehensive Environmental Response, Compensation and Liability Act of
1980 (Superfund) and the Superfund Amendments and Reauthorization Act of 1986
established a variety of informational and environmental action programs.  The
United States Environmental Protection Agency (EPA) has informed Duquesne of its
involvement or potential involvement in three hazardous waste sites.  If
Duquesne is ultimately determined to be a responsible party with respect to
these sites, it could be liable for all or a portion of the cleanup costs.
However, in each case, other solvent, potentially responsible parties that may
bear all or part of any liability are also involved.  In addition, Duquesne
believes that available defenses, along with other factors (including overall
limited involvement and low estimated remediation costs for one site) will
limit any potential liability that Duquesne may have for cleanup costs.
Duquesne believes that it is adequately reserved for all known liabilities and
costs and, accordingly, that these matters will not have a materially adverse
effect on its financial position or results of operations.

    In 1990, Congress approved amendments to the Clean Air Act.  Among other
innovations, this legislation established the Emission Allowance Trading System.
These allowances are issued by the EPA to fossil-fired stations with generating
capability of more than 25 megawatts that were in existence as of the passage of
the 1990 amendments. Allowances are part of a market-based approach to SO2
reduction.  Emission allowances can also be obtained through purchases on the
open market or directly from other sources.  Excess allowances may be banked for
future use or sold on the open market to other parties for their use in
offsetting emissions.

    The legislation requires significant additional reductions of SO2 and oxides
of nitrogen (NOX) by the year 2000.  Duquesne continues to work with the
operators of its jointly owned stations to implement cost-effective compliance
strategies to meet these requirements.  NOX reductions under Title IV of the
Clean Air Act  were required at the Cheswick station and the work to achieve the
reductions was completed in 1993.  The ozone attainment provisions of Title I of
the Clean Air Act amendments also required NOX reductions by 1995 at Duquesne's
Elrama plant and at the jointly owned Mansfield plant.  Duquesne will achieve
such reductions with low NOX burner technology.  Duquesne has 662 megawatts of
nuclear capacity currently, 1,187 megawatts of scrubbed capacity, including 300
megawatts at the currently cold-reserved Phillips plant, as well as 757
megawatts of capacity that meets the 1995 standards of the Clean Air Act
amendments through the use of low sulfur coal.  Through the year 2000, Duquesne
is planning a combination of compliance methods that include fuel switching;
increased use of, and improvements in, scrubbed capacity; flue gas conditioning;
low NOX burner technology; and the purchase of emission allowances.  Duquesne
currently estimates that additional capital costs to comply with Clean Air Act
requirements through the year 2000 will be approximately $20 million.  This
estimate is subject to the finalization of federal and state regulations.

                                       11
<PAGE>
 
    Duquesne is closely monitoring other potential air quality programs and air
emission control requirements that could be imposed in the future, including
additional NOX control requirements that could be imposed on fossil fuel plants
by the Ozone Transport Commission and promulgation by the EPA of more stringent 
ambient air quality and emission standards for SO2 particulates and other 
components of coal combustion gases.  As these potential programs are in various
stages of discussion and consideration, it is impossible to make reasonable
estimates of the potential costs and impacts, if any.

    In 1992, the Pennsylvania Department of Environmental Resources (DER) issued
Residual Waste Management Regulations governing the generation and management of
non-hazardous waste.  Duquesne is currently conducting tests and developing
compliance strategies.  Capital compliance costs for these DER regulations are
estimated, on the basis of information currently available, at $5 million in
1995.  The expected additional capital cost of compliance for these DER
regulations through 2000 is estimated, based on current information, to be
approximately $25 million; this estimate is subject to the results of continuing
ground water assessments and DER final approval of compliance plans.

    Under the Nuclear Waste Policy Act of 1982, which establishes a policy for
handling and disposing of spent nuclear fuel and requires the establishment of a
final repository to accept spent fuel, contracts for jointly owned nuclear
plants have been entered into with the United States Department of Energy
(DOE)for permanent disposal of spent nuclear fuel and high-level radioactive
waste.  The DOE has indicated that the repository will not be available for
acceptance of spent fuel before 2010.  During 1994, Duquesne increased the
storage capacity at Beaver Valley Unit 1 by equipping the spent fuel pool with
high density fuel storage racks.  On-site spent fuel storage capacities at
Beaver Valley Unit 1, Beaver Valley Unit 2 and Perry are now expected to be
sufficient until 2017, 2011, and 2009, respectively.

    Nuclear reactor licensees in the United States are assessed annually for the
decontamination and decommissioning of DOE enrichment facilities. Assessments
are based on the amount of uranium enrichment services purchased by a utility
prior to enactment of the National Energy Policy Act of 1992 (energy act) and
are to be paid by such utilities over a 15-year period. At December 31, 1994,
Duquesne's liability for contributions is approximately $9.9 million.
Contributions, when made, are recovered through the ECR.

    Duquesne is involved in various environmental matters.  Duquesne believes
that such matters, in total, will not have a materially adverse effect on its
financial position or results of operations.


Outlook
-------------------------------------------------------------------------------

Competition

    Regulatory developments in the electric utility industry are placing
increasing competitive pressures on electric utilities. The electric utility
industry is expected to continue to undergo significant changes for the
remainder of the decade.  These changes most likely will include increasing
competition in the generation and sale of electricity, increasing energy flows
resulting from open transmission access and non-regulated generation and
transmission projects outside the traditional service areas.  Duquesne, like the
industry in general, is continuing to assess the impact of these competitive
forces on its future operations.

    The National Energy Policy Act of 1992 (energy act) was designed, among
other things, to foster competition.  Among other provisions, the energy act
amends the Public Utility Holding Company Act of 1935 (1935 act) and the Federal
Power Act.  Amendments to the 1935 act create a new class of independent power
producers known as Exempt Wholesale Generators (EWGs), which are exempt from the
corporate structure regulations of the 1935 act.  EWGs, which may include
independent power producers as well as affiliates of electric utilities, do not
require Securities and Exchange Commission approval or regulation. In addition,
brokers and marketers, without owning or operating any generation or
transmission facilities, are being permitted to enter into the business of
buying and selling electric capacity and energy.

    Amendments to the Federal Power Act create the potential for utilities and
other power producers to gain increased access to transmission systems of other
utilities in order to facilitate sales to other utilities.  The amendments
permit the FERC to order utilities to transmit power over their lines for use by
other suppliers and to

                                       12
<PAGE>
 
enlarge or construct additional transmission capacity to provide these services.
Duquesne is currently pursuing expanded transmission access under these
amendments.  (See discussion in "Transmission Access" below.)

    The PUC is currently conducting an investigation into electric power
competition.  Duquesne has been advocating increased transmission access to the
wholesale power market as the necessary first step toward enabling our customers
to benefit from competition.

    Emerging competition, federal deregulation of wholesale energy sales, and
prospective retail access initiatives require Duquesne to reexamine its approach
to doing business.  Growth in energy sales, competitive rate pressures, and
Duquesne's commitment to provide reliable, quality service to its customers
influence short- and long-term corporate goals.  Duquesne's current business
plan recognizes the need to encourage economic growth and stability in the
service territory and surrounding region.  Duquesne's efforts continue to focus
on achievement of business growth through the application of marketing and
economic development programs to achieve energy-efficient growth in its sales of
utility services.  Duquesne's rates for energy intensive industrial and
commercial customers are competitively priced and its rate structure allows some
flexibility in setting rates to attract new business.  In addition, Duquesne
sponsors programs to help customers manage their electricity consumption and
control their costs.

    Although management believes Duquesne's system is well positioned, as a
clean, low cost producer of electricity, to compete both within and outside of
its service territory, efforts continue to further reduce costs and increase
effectiveness and productivity.  Management will aggressively address these
factors to position Duquesne to overcome the challenges they may create and take
advantage of the opportunities increased competition will bring.


Transmission Access

    In March 1994, Duquesne submitted, pursuant to the Federal Power Act, a
"good faith" request for transmission service with the Allegheny Power System
(APS) andPennsylvania-New Jersey-Maryland Interconnection Association (PJM
Companies).  The request is based on 20-year firm service with flexible delivery
points for 300 megawatts of transfer capability over the transmission network
that extends from Western Pennsylvania to the East Coast.  Because of a lack of
progress on pricing and other issues, on August 5, and September 16, 1994,
Duquesne filed with the FERC applications for transmission service from the PJM
Companies and APS, respectively.  The applications are authorized under Section
211 of the Federal Power Act, which requires electric utilities to provide firm
wholesale transmission service.


Retirement Plan Measurement Assumptions

    Duquesne increased the discount rate used to determine the projected benefit
obligation on Duquesne's retirement plans at December 31, 1994, to 8.0 percent.
The assumed change in future compensation levels was also increased to reflect
current market and economic conditions.

    The effects of these changes on Duquesne's retirement plan obligations are
reflected in the amounts shown inNote N to Duquesne's consolidated financial
statements.  The resulting decrease in related expenses for subsequent years is
not expected to be material.

    Duquesne owns the Warwick Mine, including 4,849 acres owned in fee of
unmined coal lands and mining rights, located on the Monongahela River in Greene
County, Pennsylvania, approximately 83 river miles from Pittsburgh.  (See Item
1. "Fossil Fuel" discussion on page 9.)

    Substantially all of Duquesne's properties are subject to a first mortgage
lien of the Trust Indenture dated as of August 1, 1947 securing Duquesne's first
mortgage bonds.  In May 1992, Duquesne began issuing secured debt under a new
First Collateral Trust Indenture.  This new indenture will ultimately replace
Duquesne's First Mortgage BondIndenture.


ITEM 3.  LEGAL PROCEEDINGS.

Westinghouse Lawsuit
-------------------------------------------------------------------------------

    Beaver Valley Unit 1 and Unit 2 are jointly owned/leased generating units.
Duquesne's percentage interests held in Beaver Valley Unit 1 and in Beaver
Valley Unit 2 are 47.5 percent and 13.74 percent, respectively.  The remainder
of Beaver Valley Unit 1 is owned by Ohio Edison Company and by Pennsylvania
Power Company.  The remaining interest in Beaver Valley Unit 2 is held by Ohio
Edison Company, The Cleveland Electric Illuminating Company (CEI) and The Toledo
Edison Company.  Duquesne operates both units on behalf of the joint owners of
interests.

    In 1991, the aforementioned owners of joint interests in Beaver Valley Unit
1 and Unit 2 filed suit against Westinghouse Electric Corporation (Westinghouse)
in the United States District Court for the Western District of Pennsylvania.
The suit alleges that six steam generators supplied by Westinghouse for the two
units contain serious defects -- in particular defects causing tube corrosion
and cracking.  To date, twelve additional lawsuits have been brought by other
utility companies around the country against Westinghouse for similar problems
with Westinghouse steam generators.

    The condition of the Beaver Valley Unit 1 and Unit 2 steam generators is
being monitored closely.  Duquesne's steam generator maintenance costs have
increased as a result of these defects and are likely to continue increasing.
Replacement of the Beaver Valley Unit 1 steam generator defective components may
occur as early as 1997.  Based on the experience of other utilities with similar
units that have replaced steam generators, replacement cost per unit is
estimated to be approximately $125 million.

    A jury trial began September 12, 1994, in Federal District Court in Western
Pennsylvania.  Pennsylvania Power Company, Ohio Edison Company, CEI, Toledo
Edison Company and Duquesne were joined in the litigation against Westinghouse.
On October 24, 1994, the Court dismissed four of the five claims against
Westinghouse, leaving only the fraud claim.  On December 6, 1994, the jury
rendered a verdict in favor of Westinghouse on the fraud count.  On January 5,
1995, the owners of joint interests in the Beaver Valley plants appealed the
decision to the United States Court of Appeals for the Third Circuit.  Duquesne
cannot predict the final outcome of this litigation; however, Duquesne does not
believe that resolution will have a materially adverse effect on Duquesne's
financial position or results of operations.

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED SHARE-
         HOLDER MATTERS.

    Effective July 7, 1989, Duquesne Light Company became a wholly owned
subsidiary of DQE, the holding company formed as part of a shareholder-approved
restructuring.  As a result of the restructuring, DQE common stock replaced all
outstanding shares of Duquesne Light Company common stock, except for ten shares
which DQE holds.  As such, this item is not applicable to Duquesne Light Company
because all its common equity is held solely by DQE.  During 1994, Duquesne
declared quarterly dividends on its common stock totaling $144 million for the
year.

------

Under the system of accounting followed by Duquesne, a portion of maintenance
expenses and of taxes other than payroll and income taxes represents amounts
charged to coal inventories. The inventory accounts are relieved and operation
expense charged as the coal is used.

(A)  Duquesne changed, as of January 1, 1993, its method of accounting for
     maintenance costs during scheduled major fossil station outages.  Prior to
     that time, maintenance costs incurred for scheduled major outages at fossil
     stations were charged to expense as these costs were incurred.  Under the
     new accounting policy, Duquesne accrues, over the periods between outages,
     anticipated expenses for scheduled major fossil station outages. 
     (Maintenance costs incurred for non-major scheduled outages and for forced
     outages will continue to be charged to expense as such costs are
     incurred.) This new method was adopted to match more accurately the
     maintenance costs and the revenue produced during the periods between
     scheduled major fossil station outages.  The cumulative effect of $5.4
     million (net of income taxes of $3.9 million) of the change on prior
     years is reflected on the Statement of Consolidated Income for 1993 as
     Accounting for maintenance costs - net.

(B)  The 1993 decrease reflects a favorable resolution of property tax
     assessments.  In 1993, Duquesne recorded on the basis of this revised
     assessment, the expected refunds of these overpayments related to prior
     years.

                          INDEPENDENT AUDITORS' REPORT



To the Directors and Stockholder of Duquesne Light Company:

       We have audited the accompanying consolidated balance sheets of Duquesne
Light Company and its subsidiary as of December 31, 1994 and 1993, and the
related consolidated statements of income, retained earnings, and cash flows for
each of the three years in the period ended December 31, 1994.  Our audits also
included the financial statement schedules listed in Item 14.  These Financial
statements and financial statement schedules are the responsibility of the
Company's management.  Our responsibility is to express an opinion on these
Financial statements and financial statement 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, such consolidated Financial statements present fairly, in
all material respects, the Financial position of Duquesne Light Company and its
subsidiary as of December 31, 1994 and 1993, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1994 in conformity with generally accepted accounting principles.  Also, in
our opinion, such financial statement schedules, when considered in relation to
the basic consolidated financial statements taken as a whole, present fairly in
all material respects the information set forth therein.

       As discussed in Note A to the consolidated financial statements,
effective January 1, 1993, the Company changed its method of accounting for
income taxes to conform with Statement of Financial Accounting Standards No.
109, and the Company changed its method of accounting for maintenance costs
during scheduled major fossil station outages.

GLOSSARY OF TERMS

Following are explanations of certain financial and operating terms used in our 
report and unique in our business.

Allowance for Funds Used During Construction (AFC)
--------------------------------------------------
AFC is an amount recorded on the books of a utility during the period of 
construction of utility assets. The amount represents the estimated cost of
both debt and equity used to finance the construction.

Construction Work In Progress (CWIP)
------------------------------------
This amount represents utility assets in the process of construction but not yet
placed in service. The amount is shown on the consolidated balance sheet as a 
component of property, plant and equipment.

Deferred Energy Costs
---------------------
In conjunction with the Energy Cost Rate Adjustment Clause, the Company records 
deferred energy costs to offset differences between actual energy costs and the 
level of energy costs currently recovered from electric utility customers.

Demand
------
The amount of electricity delivered to consumers at any instant or averaged over
a period of time.

Energy Cost Rate Adjustment Clause (ECR)
----------------------------------------
The Company recovers through the ECR, to the extent that such amounts are not 
included in base rates, the cost of nuclear fuel, fossil fuel and purchased 
power costs and passes to its customers the profits from short-term power sales 
to other utilities.

Equivalent Availability Factor
------------------------------
The percent of generating capacity available for service whether operated or
not.

Federal Energy Regulatory Commission (FERC)
-------------------------------------------
FERC is an independent five-member commission within the U.S. Department of 
Energy. Among its many responsibilities, FERC sets rates and charges for the 
wholesale transportation and sale of natural gas and electricity, and the 
licensing of hydroelectric power projects.

Kilowatt (KW)
-------------
A kilowatt is a unit of power or capacity. A kilowatt hour (KWH) is a unit of 
energy or kilowatts times the length of time the kilowatts are used. For 
example, a 100-watt bulb has a demand of .1 KW and, if burned continuously, 
will consume 1 KWH in ten hours. One thousand KWs is a megawatt (MW). One 
thousand KWHs is a megawatt hour (MWH).

Nuclear Decommissioning Costs
-----------------------------
Decommissioning costs are expenses to be incurred in connection with the 
entombment, decontamination, dismantlement, removal and disposal of the 
structures, systems and components of a nuclear power plant that has permanently
ceased the production of electric energy.

Peak Demand
-----------
Peak demand is the amount of electricity required during periods of highest 
usage. Peak periods fluctuate by season and generally occur in the morning hours
in winter and in late afternoon during the summer.

Pennsylvania Public Utility Commission (PUC)
--------------------------------------------
The Pennsylvania governmental body that regulates all utilities (electric, gas, 
telephone, water, etc.), which is made up of five members nominated by the 
governor and confirmed by the senate.

Regulatory Asset
----------------
Costs that the Company would otherwise have charged to expense which are 
capitalized or deferred because these costs are currently being recovered or 
because it is probable that the PUC and FERC will allow recovery of these costs 
through the ratemaking process.

Retail Access
-------------
The ability of end-use consumers to individually contract for electrical energy 
from competing generation suppliers.

Scrubbed Capacity
-----------------
Fossil fuel fired generating capacity equipped with sulfur dioxide (SO2) 
emission reducing equipment.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


A.  Summary of
    Significant
    Accounting
    Policies

Consolidation and Reclassifications
--------------------------------------------------------------------------------

The consolidated Financial statements include the accounts of Duquesne Light
Company (Duquesne) and its wholly owned subsidiary. All material intercompany
balances and transactions have been eliminated in the preparation of the
consolidated Financial statements.

The 1993 and 1992 financial statements have been reclassified to conform with
accounting presentations adopted during 1994.

Basis of Accounting
--------------------------------------------------------------------------------

Duquesne is subject to the accounting and reporting requirements of the
Securities and Exchange Commission (SEC). In addition, Duquesne's utility
operations are subject to the regulation of thePennsylvania Public Utility
Commission (PUC) and the Federal Energy Regulatory Commission (FERC). As a
result, the consolidated financial statements contain regulatory assets and
liabilities in accordance with Statement of Financial Accounting Standards No.
71, Accounting for the Effects of Certain Types of Regulation (SFAS No. 71) and
reflect the effects of the ratemaking process. Such effects concern mainly the
time at which various items enter into the determination of net income in
accordance with the principle of matching costs and revenues. (See Note F.)

Revenues
--------------------------------------------------------------------------------

Meters are read monthly and customers are billed on the same basis. Revenues are
recorded in the accounting periods for which they are billed, with the exception
of energy cost recovery revenues. (See following section on "Energy Cost Rate
Adjustment Clause.") Deferred revenues are associated with Duquesne's 1987 rate
case. (See Note F.)

Energy Cost Rate Adjustment Clause (ECR)
--------------------------------------------------------------------------------

Through the ECR, Duquesne recovers (to the extent that such amounts are not
included in base rates) nuclear fuel, fossil fuel and purchased power expenses
and, also through the ECR, passes to its customers the profits from short-term
power sales to other utilities (collectively, ECR energy costs). Nuclear fuel
expense is recorded on the basis of the quantity of electric energy generated
and includes such costs as the fee, imposed by the United States Department of
Energy (DOE), for future disposal and ultimate storage and disposition of spent
nuclear fuel. Fossil fuel expense includes the costs of coal, natural gas and
fuel oil used in the generation of electricity.

On Duquesne's Statement of Consolidated Income, these energy cost recovery
revenues are included as a component of operating revenues. For ECR purposes,
Duquesne defers fuel and other energy expenses for recovery, or refunding, in
subsequent years. The deferrals reflect the difference between the amount that
Duquesne is currently collecting from customers and its actual ECR energy costs.
ThePUC annually reviews Duquesne's ECR energy costs for the fiscal year April
through March, compares them to previously projected ECR energy costs and
adjusts the ECR for over- or under-recoveries and for two PUC-established coal
cost standards. (See Note F.)

Over- or under-recoveries from customers are recorded in Duquesne's Consolidated
Balance Sheet as payable to, or receivable from, customers. At December 31,
1994, $5.9 million was receivable from customers and shown as other current
assets. At December 31, 1993, $10.1 million was payable to customers and shown
as deferred energy costs.

Maintenance
--------------------------------------------------------------------------------

Incremental maintenance expense incurred for refueling outages at Duquesne's
nuclear units is deferred for amortization over the period (generally eighteen
months) between scheduled outages. Duquesne changed, as of January 1, 1993, its
method of accounting for maintenance costs during scheduled major fossil
generating station outages. Prior to that time, maintenance costs incurred for
scheduled major outages at fossil generating stations were charged to expense as
these costs were incurred. Under the new accounting policy, Duquesne accrues,
over the

                                       45
<PAGE>
 
periods between outages, anticipated expenses for scheduled major fossil
generating station outages. (Maintenance costs incurred for non-major scheduled
outages and for forced outages continue to be charged to expense as such costs
are incurred.) This method was adopted to match more accurately the maintenance
costs and the revenue produced during the periods between scheduled major fossil
generating station outages.

The cumulative effect (approximately $5.4 million, net of income taxes of
approximately $3.9 million) of the change on prior years was included in net
income in 1993. The effect of the change in 1993 was to reduce income, before
the cumulative effect of changes in accounting principles, by approximately $2.4
million and to reduce net income, after the cumulative effect of changes in
accounting principles, by approximately $7.8 million.

Depreciation and Amortization
--------------------------------------------------------------------------------

Depreciation of property, plant and equipment, including plant-related
intangibles, is recorded on a straight-line basis over the estimated useful
lives of properties. Amortization of other intangibles is recorded on a
straight-line basis over a five-year period. Depreciation and amortization of
other properties are calculated on various bases.

Duquesne records decommissioning costs under the category of depreciation and
amortization expense and accrues a liability, equal to that amount, for nuclear
decommissioning expense. Such nuclear decommissioning funds are deposited in
external, segregated trust accounts. The funds are invested in a portfolio
consisting of municipal bonds, certificates of deposit, and U.S. government
securities. Trust fund earnings increase the fund balance and the recorded
liability. The market value of the aggregate trust fund balances at December 31,
1994, totaled $19.2 million. On Duquesne's consolidated balance sheet, the
decommissioning trusts have been reflected in other property and investments,
and the related liability has been recorded as other non-current liabilities.
(See "Nuclear Decommissioning" discussion in Note L.)

Income Taxes
--------------------------------------------------------------------------------

On January 1, 1993, Duquesne adopted Statement of Financial Accounting Standards
No. 109, Accounting for Income Taxes (SFAS No. 109). Implementation of SFAS No.
109 involved a change in accounting principle. The cumulative $8 million effect
on prior years was reported in 1993 as an increase in net income.

SFAS No. 109 requires that the liability method be used in computing deferred
taxes on all differences between book and tax bases of assets. These book tax
differences occur when events and transactions recognized for financial
reporting purposes are not recognized in the same period for tax purposes. SFAS
No. 109 also requires that a deferred tax liability or asset be adjusted in the
period of enactment for the effect of changes in tax laws or rates. During 1994
the statutory Pennsylvania income tax rate was reduced from 12.25 percent to
9.99 percent; this reduction is to be phased in over four years. This resulted
in a net decrease of $87.2 million in deferred tax liabilities and a
corresponding reduction in the regulatory receivable.

Duquesne recognizes a regulatory asset for the deferred tax liabilities that are
expected to be recovered from customers through rates. (See Notes F and K.)

With respect to the financial statement presentation of SFAS No. 109, Duquesne
reflects the amortization of the regulatory tax receivable resulting from
reversals of deferred taxes as depreciation and amortization expense. Changes in
the regulatory tax receivable as a result of a change in tax rates are reflected
in the statement of consolidated income on the tax rate adjustment - regulatory
tax receivable line. Reversals of accumulated deferred income taxes are included
in income tax expense.

When applied to reduce Duquesne's income tax liability, investment tax credits
related to utility property generally were deferred. Such credits are
subsequently reflected, over the lives of the related assets, as reductions to
tax expense.

                                       46
<PAGE>
 
Property, Plant and Equipment
--------------------------------------------------------------------------------

The asset values of Duquesne's properties are stated at original construction
cost, which includes related payroll taxes, pensions, and other fringe benefits,
as well as administrative and general costs. Also included in original
construction cost is an allowance for funds used during construction (AFC),
which represents the estimated cost of debt and equity funds used to finance
construction. The amount of AFC that is capitalized will vary according to
changes in the cost of capital and in the level of construction work in progress
(CWIP). On a current basis, Duquesne does not realize cash from the allowance
for funds used during construction. Duquesne does realize cash, during the
service life of the plant, through increased revenues reflecting a higher rate
base (upon which a return is earned) and increased depreciation. The AFC rates
applied to CWIP were 9.0 percent in 1994, 9.6 percent in 1993, and 10.3 percent
in 1992.

Additions to, and replacements of, property units are charged to plant accounts.
Maintenance, repairs and replacement of minor items of property are recorded as
expenses when they are incurred. The costs of properties that are retired (plus
removal costs and less any salvage value) are charged to the accumulated
provision for depreciation.

Substantially all of Duquesne's properties are subject to first mortgage liens,
and to junior liens.

Temporary Cash Investments
--------------------------------------------------------------------------------

Temporary cash investments are short-term, highly liquid investments with
original maturities of three or fewer months. They are stated at market, which
approximates cost. Duquesne considers temporary cash investments to be cash
equivalents.



B.  Property, Plant
    and Equipment

Duquesne's net investment in property, plant and equipment at December 31, 1994
and 1993, was $3,068,519 and $3,123,948, respectively. Duquesne's total
investment in property, plant and equipment and the related accumulated
depreciation balances for the following major classes of property at December
31, 1994 and 1993 are as follows:

In addition to its wholly owned generating units, Duquesne, together with other
electric utilities, has an ownership or leasehold interest in certain jointly
owned units. Duquesne is required to pay its share of the construction and
operating costs of the units. Duquesne's share of the operating expenses of the
units is included in the statement of consolidated income.

Duquesne has a 13.74 percent ownership interest in Perry Unit 1, a nuclear
generating unit located in Ohio and operated by The Cleveland Electric
Illuminating Company (CEI). During 1993, the unit had an equivalent availability
factor of 39 percent. This performance resulted from several outages. As a
result of the length of these outages, the PUC imposed a penalty for incremental
replacement power costs. The 1994 equivalent availability factor was 44 percent.
This performance resulted from an extended outage (190 days) for refueling and
maintenance. From the end of the outage in August 1994 through the balance of
1994, Perry operated at full capacity except for short durations of reduced
power for testing and minor on-line maintenance activities.

In November 1993, CEI submitted to the Nuclear Regulatory Commission an action
plan, called the Perry Course of Action (PCA), designed by CEI to "correct
identified management, technical, and programmatic deficiencies" at the plant
over roughly a three-year period, and to "correct the downward trending
performance" of Perry. CEI management represents to Duquesne that the PCA is on
schedule and will be an effective program to insure that Perry is in conformance
with industry standards for boiling water reactors. Based on actual costs and
estimates obtained from CEI through January 1995, the total costs to bring the
plant into compliance, including the costs associated with implementing the PCA,
are more than the costs originally projected by CEI. Duquesne cannot predict the
ultimate cost, timing or effectiveness of the PCA, and is continuing to closely
monitor the situation.



C.  Leases

Duquesne leases nuclear fuel, a portion of a nuclear generating plant, certain
office buildings, computer equipment and other property and equipment.

In 1987, Duquesne sold its 13.74 percent interest in Beaver Valley Unit 2; the
sale was exclusive of transmission and common facilities. The total sales price
of $537.9 million was the appraised value of Duquesne's interest in the
property. Duquesne leased back its interest in the unit for a term of 29.5
years. The lease provides for semiannual payments and is accounted for as an
operating lease. Duquesne is responsible under the terms of the lease for all
costs of its interest in the unit. In December 1992, Duquesne participated in
the refinancing of collateralized lease bonds to take advantage of lower
interest rates and reduce the annual lease payments. The bonds were originally
issued in 1987 for the purpose of partially financing the lease of Beaver Valley
Unit 2. In accordance with the Beaver Valley Unit 2 lease agreement, Duquesne
paid the premiums of approximately $36.4 million as a supplemental deferred rent
payment to the lessors. This amount was deferred and is being amortized over the
remaining lease term. At December 31, 1994, the deferred balance was
approximately $33.4 million.

Leased nuclear fuel is amortized as the fuel is burned. The amortization of all
other leased property is based on rental payments made. Payments for capital and
operating leases are charged to operating expenses on the statement of
consolidated income.

(a) Includes current obligations of $26.1 million at December 31, 1994.

Future payments due to Duquesne, as of December 31, 1994, under subleases of
certain corporate office space are approximately $1.2 million in 1995, $3.8
million in 1996 and $30 million thereafter.



D. Other Property
   and Investments

At December 31, 1994 and 1993, the fair market value of Duquesne's investment in
DQE common stock was $43.1 million and $34.0 million, respectively.  At December
31, 1994 and 1993, the cost of Duquesne's investment in DQE common stock was
$45.9 million and $30.0 million, respectively.

Duquesne's other investments are primarily in assets of a nuclear
decommissioning trust and marketable securities. In accordance with Statement of
Financial Accounting Standards No. 115, Accounting for Certain Investments in
Debt and Equity Securities (SFAS No. 115), these investments are classified as
available-for-sale and are stated at market value. The amounts of unrealized
holding gains at December 31, 1994 are not material.



E.  Receivables

Duquesne and an unaffiliated corporation have an agreement that entitles
Duquesne to sell and the corporation to purchase, on an ongoing basis, up to $50
million of accounts receivable.  Duquesne had no receivables sold at December
31, 1994.  The accounts receivable sales agreement, which expires in June 1995,
is one of many sources of funds available to Duquesne.  Upon expiration of this
facility, Duquesne expects to extend the agreement or to replace the facility
with a similar one.



F.  Rate Matters

1987 Rate Case
--------------------------------------------------------------------------------
In March 1988, the PUC adopted a rate order that increased Duquesne's revenues
by $232 million annually. This rate increase was phased-in from April 1988
through April 1994. Deficiencies in current revenues which resulted from the
phase-in plan were included in the statement of consolidated income as phase-in
deferrals. Phase-in deferrals  were recorded on the balance sheet as a
regulatory asset. As customers were billed for deficiencies related to prior
periods, this regulatory asset was reduced.

At this time, Duquesne has no pending base rate case and has no immediate plans
to file a base rate case.

                                       50
<PAGE>
 
Deferred Rate Synchronization Costs
--------------------------------------------------------------------------------
In the 1987 Rate Case, the PUC approved Duquesne's petition to defer initial
operating and other costs of Perry Unit 1 and Beaver Valley Unit 2. Duquesne
deferred the costs incurred from November 17, 1987, when the units went into
commercial operation, until March 25, 1988, when a rate order was issued. In its
order, the PUC deferred ruling on whether these costs would be recoverable from
ratepayers. Duquesne is not earning a return on the deferred costs.

Duquesne believes that these deferred costs are recoverable. In 1990, the PUC
permitted another Pennsylvania utility to recover such costs.

Extraordinary Property Loss
--------------------------------------------------------------------------------
Duquesne abandoned its interest in the partially-constructed Perry Unit 2 in
1986 and subsequently disposed of its interest in 1992. In the 1987 Rate Case,
the PUC approved recovery, over a 10-year period, of Duquesne's original $155
million investment in Perry Unit 2.  Duquesne is not earning a return on the as
yet unrecovered portion (approximately $23.9 million at December 31, 1994) of
its investment in the unit.

Deferred Coal Costs
--------------------------------------------------------------------------------
The PUC has established two market price coal cost standards for Duquesne's
interests in mines that supply coal to its generating stations. One applies only
to coal delivered at the Mansfield plant. The other, the system-wide coal cost
standard, applies to coal delivered to the remainder of Duquesne's system. Both
standards are updated monthly to reflect prevailing market prices for similar
coal. The PUC has directed Duquesne to defer recovery of the delivered cost of
coal to the extent that such cost exceeds generally prevailing market prices, as
determined by the PUC, for similar coal. The PUC allows deferred amounts to be
recovered from customers when the delivered costs of coal fall below such PUC-
determined prevailing market prices.

In 1990, the PUC approved a joint petition for settlement that clarified certain
aspects of the system-wide coal cost standard and gave Duquesne options to
extend the standard through March 2000. In December 1991, Duquesne exercised the
first of two options that extended the standard through March 1996. The
unrecovered cost of coal used at Mansfield amounted to $7.3 million and $7.4
million and the unrecovered cost of coal used throughout the system amounted to
$3.4 million and $8.8 million at December 31, 1994 and 1993, respectively.
Duquesne believes that all deferred coal costs will be recovered.

Warwick Mine Costs
--------------------------------------------------------------------------------
The 1990 joint petition for settlement (see preceding section on deferred coal
costs) also recognized costs at Duquesne's Warwick Mine, which had been on
standby since 1988, and allowed for recovery of such costs, including the costs
of ultimately closing the mine. In 1990, Duquesne entered into an agreement
under which an unaffiliated company will operate the mine until March 2000 and
sell the coal produced. Production began in late 1990. The mine reached a full
production rate in early 1991. The Warwick Mine coal reserves include both high
and low sulfur coal; Duquesne's contract is for medium to high sulfur (1.3
percent-2.5 percent) coal. More than 60 percent of the coal mined at Warwick
currently is used by Duquesne. Duquesne receives a royalty on sales of Warwick
coal in the open market. In the past year, the Warwick Mine supplied slightly
less than one-fifth of the coal used in the production of electricity at
Duquesne's wholly owned and jointly owned plants.

Costs at the Warwick Mine and Duquesne's investment in the mine are expected to
be recovered through the cost of coal in the ECR. Recovery is subject to the
system-wide coal cost standard. Duquesne also has an opportunity to earn a
return on its investment in the mine through the cost of coal during the period
of the system-wide coal cost standard, including extensions. At December 31,
1994, Duquesne's net investment in the mine was $18.9 million. The estimated
liability, including final site reclamation, mine water treatment and certain
labor liabilities, for mine closing is $33 million and Duquesne has recorded a
liability in the consolidated balance sheet of approximately $12.8 million
toward these costs.

Property Held for Future Use
--------------------------------------------------------------------------------
In 1986, the PUC approved Duquesne's request to remove the Phillips and most of
the Brunot Island (BI) power stations from service and place them in cold
reserve. Duquesne expects to recover its net investment in these plants through
future electricity sales. Phillips and BI represent licensed, certified, clean
sources of electricity that will be necessary to meet expanding opportunities in
the bulk power markets. Duquesne believes that anticipated growth in peak load
demand for electricity within its service territory will require additional
peaking generation. Duquesne looks to BI to meet this need. The Phillips power
plant is an important component in Duquesne's strategy to identify and serve
opportunities for providing bulk power service. With recent legislation
promoting wider transmission access to bulk power markets and with the
opportunity to package a sale of power from Phillips with the support of
Duquesne's system, the Phillips plant could be made a highly reliable, cost-
competitive alternative for most purchasers. In summary, the Company believes
its investment in these cold-reserved plants will be necessary in order to meet
future business needs. If business opportunities do not develop as expected,
Duquesne will consider the sale of these assets. In the event that market
demand, transmission access or rate recovery do not support the utilization or
sale of the plants, Duquesne may have to write off part or all of their costs.
At December 31, 1994, the Company's net investment in Phillips and BI was $93.0
million and $42.0 million, respectively.



G.  Common Stock
    and Capital
    Surplus

Common Stock and Capital Surplus
--------------------------------------------------------------------------------
In July 1989, Duquesne became a wholly owned subsidiary of DQE, the holding
company formed as part of a shareholder-approved restructuring. As a result of
the restructuring, DQE common stock replaced all outstanding shares of Duquesne
common stock, except for ten shares which DQE holds.

DQE or its predecessor, Duquesne, has continuously paid dividends on common
stock since 1953. Dividends may be paid on DQE common stock to the extent
permitted by law and as declared by its board of directors. However, in
Duquesne's Restated Articles of incorporation, provisions relating to preferred
and preference stock may restrict the payment of Duquesne's common dividends. No
dividends or distributions may be made on Duquesne's common stock if Duquesne
has not paid dividends or sinking fund obligations on its preferred or
preference stock. Further, the aggregate amount of Duquesne's common stock
dividend payments or distributions may not exceed certain percentages of net
income if the ratio of common stockholder's equity to total capitalization is
less than specified percentages. As all of Duquesne's common stock is owned by
DQE, to the extent that Duquesne cannot pay common dividends, DQEmay not be able
to pay dividends to its common stockholders. No part of the retained earnings of
Duquesne was restricted at December 31, 1994.

H.  Preferred and
    Preference Stock

Holders of Duquesne's preferred stock are entitled to cumulative quarterly
dividends. If four quarterly dividends on any series of preferred stock are in
arrears, holders of the preferred stock are entitled to elect a majority of
Duquesne's board of directors until all dividends have been paid. At December
31, 1994, Duquesne had made all preferred stock dividend payments.

Holders of Duquesne's preference stock are entitled to receive cumulative
quarterly dividends if dividends on all series of preferred stock are paid. If
six quarterly dividends on any series of preference stock are in arrears,
holders of the preference stock are entitled to elect two of Duquesne's
directors until all dividends have been paid. At December 31, 1994, the Company
had made all dividend payments.

                                       52
<PAGE>
 
Outstanding preferred and preference stock is generally callable, on notice of
not less than thirty days, at stated prices plus accrued dividends. On January
14, 1994, Duquesne called for redemption all of its outstanding shares of $2.10
and $7.50 preference stock. None of the remaining preferred or preference stock
issues has mandatory purchase requirements.

In December 1991, Duquesne established an Employee Stock Ownership Plan (ESOP)
to provide matching contributions for a 401(k) Retirement Savings Plan for
Management Employees. (See Note N.) Duquesne issued and sold 845,070 shares of
preference stock, plan series A to the trustee of the ESOP. As consideration for
the stock, Duquesne received a note valued at $30 million from the trustee. The
preference stock has an annual dividend rate of $2.80 per share, and each share
of the preference stock is exchangeable for one share of DQE common stock. At
December 31, 1994, $24.9 million of preference stock issued in connection with
the establishment of the ESOP had been offset, for financial statement purposes,
by the recognition of a deferred ESOP benefit. Dividends on the preference stock
and cash contributions from Duquesne are used to repay the ESOP note. Duquesne
made cash contributions of approximately $2.3 million for 1994, $2.1 million for
1993, and $4.9 million for 1992. These cash contributions were the difference
between the ESOP debt service and the amount of dividends on ESOP shares
(approximately $2.4 million in 1994, $2.3 million in 1993 and $2.5 million in
1992). As shares of preference stock are allocated to the accounts of
participants in the ESOP, Duquesne recognizes compensation expense, and the
amount of the deferred compensation benefit is amortized. Duquesne recognized
compensation expense related to the 401(k) plan of $1.8 million in 1994, $1.7
million in 1993, and $1.5 million in 1992.

I.  Long-Term Debt

During 1992, Duquesne began issuing secured debt under a new first collateral
trust indenture. This indenture will ultimately replace Duquesne's 1947 first
mortgage bond indenture. First collateral trust bonds totaling $695 million with
an average interest rate of 6.58 percent were issued in 1993.

The pollution control notes arise from the sale of bonds by public authorities
for the purposes of financing construction of pollution control facilities at
Duquesne's plants or refunding previously issued bonds.

Duquesne is obligated to pay the principal and interest on the bonds. For
certain of the pollution control notes, there is an annual commitment fee for an
irrevocable letter of credit.

Under certain circumstances, the letter of credit is available for the payment
of interest on, or redemption of, a portion of the notes. In late 1994,
pollution control notes totaling $114.1 million with an average interest rate of
10.34 percent were refinanced at lower adjustable interest rates.

    first mortgage bonds.
(b) Excludes $49.0 million related to a current maturity on June 1, 1995.
(c) Excludes $0.9 million related to sinking fund requirements on the underlying
    first mortgage bonds.
(d) The pollution control notes have adjustable interest rates. The interest
    rates at year-end averaged 4.3% in 1994 and 2.6% in 1993.
(e) As of January 1995, the sinking fund requirement for 1995 had been met and
    the requirements for 1996 had been partially satisfied.

At December 31, 1994, sinking fund requirements and maturities of long-term debt
outstanding for the next five years were: $10.5 million and $49.1 million in
1995; $11.0 million and $50.1 million in 1996; $10.7 million and $50.0 million
in 1997; $9.9 million and $75.0 million in 1998; and $9.9 million and $75.0
million in 1999.

Sinking fund requirements relate primarily to the first mortgage bonds and may
be satisfied by cash or the certification of property additions equal to 166-2/3
percent of the bonds required to be redeemed. During 1994, annual sinking fund
requirements of $.5 million were satisfied by cash and $10.9 million by
certification of property additions.

Total interest costs incurred were $110.7 million in 1994, $118.1 million in
1993 and $133.9 million in 1992. Of these amounts, $2.0 million in 1994, $2.0
million in 1993 and $4.7 million in 1992 were capitalized as AFC. Debt discount
or premium and related issuance expenses are amortized over the lives of the
applicable issues.

In 1992, Duquesne was involved in the issuance of $419.0 million of
collateralized lease bonds, which were originally issued by an unaffiliated
corporation for the purpose of partially financing the lease of Beaver Valley
Unit 2. Duquesne is also associated with a letter of credit securing the
lessors' equity interest in the unit and certain tax benefits. During 1994,
Duquesne's Beaver Valley Unit 2 lease arrangement was amended to reflect an
increase in federal income tax rates. At the same time, the associated letter of
credit securing the lessor's equity interest in the unit was increased from $188
million to $194 million and the term of the letter of credit was

                                       54
<PAGE>
 
extended to 1999. If certain specified events occur, the letter of credit could
be drawn down by the owners, the leases could terminate and the bonds would
become direct obligations of Duquesne.

At December 31, 1994 and 1993, Duquesne was in compliance with all of its debt
covenants.

At December 31, 1994, the fair value of Duquesne's long-term debt, including
current maturities and sinking fund requirements, estimated on the basis of
quoted market prices for the same or similar issues or current rates offered to
Duquesne for debt of the same remaining maturities, was $1,344.7 million. The
principal amount included in Duquesne's balance sheet is $1,433.0 million.



J.  Short-Term
    Borrowing and
    Revolving Credit
    Arrangements

Duquesne has an extendible revolving credit agreement with a group of banks
totaling $150 million.  The current expiration date of this credit arrangement
is October 6, 1995.  Interest rates can, in accordance with the option selected
at the time of each borrowing, be based on prime, Eurodollar or certificate of
deposit rates. Commitment fees are based on the unborrowed amount of the
commitments.  The arrangement contains a two-year repayment period for any
amounts outstanding at the expiration of the revolving credit period.

During 1994 and 1993, the maximum short-term bank and commercial paper
borrowings outstanding were $25.6 million and $27 million; the average daily
short-term borrowings outstanding were $1.9 million and $1.6 million; and the
weighted average daily interest rates applied to such borrowings were 5.23
percent and 3.42 percent, respectively.  At December 31, 1994, there were no
short-term borrowings. Short-term borrowings at December 31, 1993, were $11.0
million.



K.  Income Taxes

Since DQE's formation in 1989, Duquesne has filed consolidated federal income
tax returns with its parent and other companies in the affiliated group.
Duquesne's federal income tax returns have been audited by the Internal Revenue
Service and closed for the tax years through 1989.

Returns filed for the tax years 1990 to date remain subject to IRS review.
Duquesne does not believe that final settlement of the federal income tax
returns for these years will have a materially adverse effect on its financial
position or results of operations. The effects of the 1993 adoption of SFAS No.
109 are discussed in Note A. Implementation of the standard involved a change in
accounting principle. The cumulative effect of $8 million on prior years was
reported in 1993 as an increase in net income. The SFAS No. 109 impact on 1993
income before cumulative effect of changes in accounting principles is
immaterial.

L.  Commitments and
    Contingencies

Construction
--------------------------------------------------------------------------------
Duquesne estimates that it will spend approximately $80 million annually on
construction during 1995, 1996 and 1997. These amounts exclude AFC, nuclear
fuel, expenditures for possible early replacement of steam generators at the
Beaver Valley Station (See "Nuclear Litigation" discussion on page 59.) and
expenditures for the refurbishment of the cold-reserved units. (See "Property
Held For Future Use" discussion on page 53.)

Nuclear-Related Matters
--------------------------------------------------------------------------------
Duquesne operates two nuclear units and has an ownership interest in a third.
The operation of a nuclear facility involves special risks, potential
liabilities and specific regulatory and safety requirements. Specific
information about risk management and potential liabilities is discussed below.

Nuclear Decommissioning. The PUC ruled that recovery of the decommissioning
costs for Beaver Valley Unit 1 could begin in 1977, and that recovery for Beaver
Valley Unit 2 and Perry Unit 1 could begin in 1988. Duquesne expects to
decommission Beaver Valley Unit 2 and Perry Unit 1 following the end of their
operating lives, a date that currently coincides with the expiration of each
plant's operating license. Upon expiration of the Beaver Valley Unit 1 operating
license, the unit will be placed in safe storage until the expiration of the
Beaver Valley Unit 2 operating license, at which time the units may be
decommissioned together.

Based upon site specific studies finalized in 1992 for Beaver Valley Unit 2, and
in 1994 for Beaver Valley Unit 1 and Perry Unit 1, Duquesne's share of the total
estimated decommissioning costs, including removal and decontamination costs,
currently being used to determine Duquesne's cost of service, are $122 million
for Beaver Valley Unit 1, $35 million for Beaver Valley Unit 2, and $67 million
for Perry Unit 1.

In conjunction with an August 18, 1994 PUC Accounting Order, Duquesne has
increased the annual contribution to its decommissioning trusts by approximately
$2 million to bring the total annual funding to approximately $4 million per
year. Duquesne plans to continue making periodic reevaluations of estimated
decommissioning costs, to provide additional funding from time to time, and to
seek regulatory approval for recognition of these increased funding levels.

Nuclear Insurance.  All of the companies with an interest in the Beaver Valley
Power Station maintain the maximum available nuclear insurance for the $5.9
billion total investment in Beaver Valley Units 1 and 2. The insurance program
provides $2.8 billion for property damage, decommissioning, and decontamination
liabilities. Similar property insurance is held by the joint owners of the Perry
plant for their $5.5 billion total investment in Perry Unit 1. Duquesne would be
responsible for its share of any damages in excess of insurance coverage. In
addition, if the property damage reserves of Nuclear Electric Insurance Limited
(NEIL), an industry mutual, are inadequate to cover claims arising from an
incident at any United States nuclear site covered by that insurer, Duquesne
could be assessed retrospective premiums totaling a maximum of $6.5 million.

The Price-Anderson Amendments to the Atomic Energy Act limit public liability
from a single incident at a nuclear plant to $8.9 billion. Duquesne has
purchased $200 million of insurance, the maximum amount available, which
provides the first level of financial protection.

Additional protection of $8.3 billion would be provided by an assessment of up
to $75.5 million per incident on each nuclear unit in the United States.
Duquesne's maximum total assessment, $56.6 million, which is based upon its
ownership or leasehold interests in three nuclear generating stations, would be
limited to a maximum of $7.5 million per incident per year. A further surcharge
of 5 percent could be levied if the total amount of public claims exceeded the
funds provided under the assessment program. Additionally, a state premium tax
(typically 3 percent) would be charged on the assessment and surcharge. Finally,
the United States Congress could impose other revenue-raising measures on the
nuclear industry if funds prove insufficient to pay claims.

                                       57
<PAGE>
 
Duquesne carries extra expense insurance; coverage includes the incremental cost
of any replacement power purchased (in addition to costs that would have been
incurred had the units been operating) and other incidental expense after the
occurrence of certain types of accidents at its nuclear units. The amounts of
the coverage are 100 percent of the estimated extra expense per week during the
52-week period starting 21 weeks after an accident and 80 percent of such
estimate per week for the following 104 weeks. The amount and duration of actual
extra expense could substantially exceed insurance coverage.

Nuclear Litigation. In 1991, Pennsylvania Power Company, Ohio Edison Company,
Cleveland Electric Illuminating Company, Toledo Edison Company and Duquesne were
joined in the litigation against Westinghouse Electric Corporation
(Westinghouse) in the United States District Court for the Western District of
Pennsylvania. In the suit, the owners allege that six steam generators supplied
by Westinghouse for Beaver Valley Units 1 and 2 contain serious design defects--
in particular defects causing tube corrosion and cracking.

Steam generator maintenance costs have increased as a result of these defects
and are likely to continue increasing. The condition of the steam generators is
being monitored closely. Replacement of the Beaver Valley Unit 1 steam generator
defective components may occur as early as 1997. Based upon other utilities with
similar units who have replaced steam generators, replacement cost per unit is
estimated to be approximately $125 million. To date, twelve additional lawsuits
have been brought by other utility companies around the country against
Westinghouse for similar problems with Westinghouse steam generators.

A jury trial began September 12, 1994 in Federal District Court in Western
Pennsylvania. On October 24, 1994, the Court dismissed four of the five claims
against Westinghouse, leaving only the fraud claim. On December 6, 1994, the
jury rendered a verdict in favor of Westinghouse on the fraud count. On January
5, 1995, the owners of the Beaver Valley plant appealed the decision to the
United States Court of Appeals for the Third Circuit. Duquesne cannot predict
the outcome of this litigation; however, the Company does not believe that
resolution will have a materially adverse effect on its financial position or
results of operations. The Company's percentage interests (ownership and
leasehold) in Beaver Valley Unit 1 and in Beaver Valley Unit 2 are 47.5 percent
and 13.74 percent, respectively. The remainder of Beaver Valley Unit 1 is owned
by Ohio Edison Company and Pennsylvania Power Company.

The remaining interest in Beaver Valley Unit 2 is held by Ohio Edison Company,
Cleveland Electric Illuminating Company and Toledo Edison Company. Duquesne
operates both units on behalf of these owners.

Spent Nuclear Fuel Disposal.  Under the Nuclear Waste Policy Act of 1982, which
establishes a policy for handling and disposing of spent nuclear fuel and
requires the establishment of a final repository to accept spent fuel, contracts
for jointly owned nuclear plants have been entered into with the DOE for
permanent disposal of spent nuclear fuel and high-level radio-active waste. The
DOE has indicated that the repository will not be available for acceptance of
spent fuel before 2010. Existing on-site spent fuel storage capacities at Beaver
Valley Unit 1, Beaver Valley Unit 2 and Perry are expected to be sufficient
until 2017, 2011, and 2009, respectively. During 1994, Duquesne increased the
storage capacity at Beaver Valley Unit 1 by equipping the spent fuel pool with
high density fuel storage racks.

Uranium Enrichment Decontamination and Decommissioning Fund.  Nuclear reactor
licensees in the United States are assessed annually for the decontamination and
decommissioning of DOE enrichment facilities. Assessments are based on the
amount of uranium a utility had processed for enrichment prior to enactment of
the National Energy Policy Act of 1992 (energy act) and are to be paid by such
utilities over a 15-year period. At December 31, 1994, Duquesne's liability for
contributions is approximately $9.9 million. Contributions, when made, are
recovered through the ECR.

Guarantees
--------------------------------------------------------------------------------
Duquesne and the other co-owners have guaranteed certain debt and lease
obligations related to a coal supply contract for the Bruce Mansfield plant. At
December 31, 1994, Duquesne's share of these guarantees was $30.3 million. The
prices paid for the coal by the companies under this

                                       58
<PAGE>
 
contract are expected to be sufficient to meet debt and lease obligations to be
satisfied in the year 2000. (See Note F.) The minimum future payments to be made
by Duquesne solely in relation to these obligations are $6.6 million in 1995,
$6.2 million in 1996, $5.9 million in 1997, $5.6 million in 1998, $5.3 million
in 1999, and $4.2 million in 2000. Duquesne's total payments for coal purchased
under the contract were $23.3 million in 1994, $26.5 million in 1993, and $25.2
million in 1992.

Residual Waste Management Regulations
--------------------------------------------------------------------------------
In 1992, the Pennsylvania Department of Environmental Resources (DER) issued
Residual Waste Management Regulations governing the generation and management of
non-hazardous waste. Duquesne is currently conducting tests and developing
compliance strategies. Capital compliance costs are estimated, on the basis of
information currently available, at $5 million in 1995. The expected additional
capital cost of compliance through 2000 is estimated, based on current
information, to be approximately $25 million; this estimate is subject to the
results of continuing ground water assessments and DER final approval of
compliance plans.

Other
--------------------------------------------------------------------------------
Duquesne is involved in various other legal proceedings and environmental
matters. Duquesne believes that such proceedings and matters, in total, will not
have a materially adverse effect on its Financial position or results of
operations.

Retirement Plans
--------------------------------------------------------------------------------
Duquesne maintains retirement plans to provide pensions for all full-time
employees. Upon retirement, an employee receives a monthly pension based on his
or her length of service and compensation. The cost of funding the pension plan
is determined by the unit credit actuarial cost method. Duquesne's policy is to
record this cost as an expense and to fund the pension plans by an amount that
is at least equal to the minimum funding requirements of the Employee Retirement
Income Security Act (ERISA) but not to exceed the maximum tax deductible amount
for the year. Pension costs charged to expense or construction were $8.9 million
for 1994, $9.8 million for 1993 and $11.4 million for 1992.

Retirement Savings Plan and Other Benefit Options
--------------------------------------------------------------------------------
Duquesne sponsors separate 401(k) retirement plans for its union-represented,
International Brotherhood of Electrical Workers (IBEW), employees and its
management employees.

The 401(k) Retirement Savings Plan for Management Employees provides that
Duquesne will match employee contributions to a 401(k) account up to a maximum
of 6 percent of his or her eligible salary. Duquesne match consists of a $.25
base match per eligible contribution dollar and an additional $.25 incentive
match per eligible contribution dollar, if Board-approved targets are achieved.
The 1994 incentive target was accomplished. Duquesne is funding its matching
contributions to the 401(k) Retirement Savings Plan for Management Employees
with payments to an ESOP established in December 1991. (See Note H.)

The 401(k) Retirement Savings Plan for IBEW Represented Employees provides that
beginning in 1995, the Company will match employee contributions to a 401(k)
account up to a maximum of 4 percent of his or her eligible salary. Duquesne
match consists of a $.25 base match per eligible contribution dollar and an
additional $.25 incentive match per eligible contribution dollar, if certain
Non-Occupational Illness and Injury targets are met.

DQE's shareholders have approved a long-term incentive plan through which
Duquesne may grant management employees options to purchase, during the years
1987 through 2003, up to a total of five million shares of DQE common stock at
prices equal to the fair market value of such stock on the dates the options
were granted. At December 31, 1994, approximately 2.3 million of these shares
were available for future grants.

As of December 31, 1994, 1993 and 1992, respectively, active grants totaled
1,412,000; 1,175,000; and 848,000 shares. Exercise prices of these options
ranged from $12.3125 to $34.625 at December 31, 1994 and December 31, 1993 and
from $12.3125 to $28.75 at December 31, 1992. Expiration dates of these grants
ranged from 1997 to 2004 at December 31, 1994; from 1997 to 2003 at December 31,
1993; and from 1997 to 2002 at December 31, 1992. As of December 31, 1994, 1993
and 1992, respectively, stock appreciation rights (SARs) had been granted in
connection with 793,000; 795,000; and 623,000 of the options outstanding. During
1994, 836,000 SARs were exercised; 226,000 options were exercised at prices
ranging from $12.3125 to $28.375; and 187,000 options lapsed. During 1993,
748,000 SARs were exercised; 151,000 options were exercised at prices ranging
from $12.3125 to $28.375; and 152,000 options lapsed. During 1992, 108,000 SARs
were exercised; 50,000 options were exercised at prices ranging from $12.3125 to
$26.375; and 59,000 options lapsed. Of the active grants at December 31, 1994,
1993 and 1992, respectively, 612,000; 578,000; and 232,000 were not exercisable.

Other Postretirement Benefits
--------------------------------------------------------------------------------
In addition to pension benefits, Duquesne provides certain health care benefits
and life insurance for some retired employees. Substantially all of Duquesne's
full-time employees may, upon attaining the age of 55 and meeting certain
service requirements, become eligible for the same benefits available to retired
employees. Participating retirees make contributions, which are adjusted
annually, to the health care plan. The life insurance plan is non-contributory.
Company-provided health care benefits terminate when covered individuals become
eligible for Medicare benefits or reach age 65, whichever comes first. Duquesne
funds actual expenditures for obligations under the plans on a "pay-as-you-go
basis." Duquesne has the right to modify or terminate the plans.

As of January 1, 1993, Duquesne adopted Statement of Financial Accounting
Standards No. 106, Employers' Accounting for Postretirement Benefits Other Than
Pensions, which requires the actuarially determined costs of the aforementioned
postretirement benefits to be accrued over the period from the date of hire
until the date the employee becomes fully eligible for benefits. Duquesne has
adopted the new standard prospectively and has elected to amortize the
transition liability over 20 years.

ORIGINAL ISSUE DATE:                     STATED MATURITY DATE:


     DUQUESNE LIGHT COMPANY, a corporation organized and existing under and by
virtue of the laws of the Commonwealth of Pennsylvania (hereinafter called the
"Company"), for value received, hereby promises to pay to ____________ or
registered assigns the sum of _________________ Dollars in lawful money of the
United States of America on the Stated Maturity Date specified above.  This bond
shall not bear interest except that, if the Company should default in the
payment of the principal hereof, this bond shall bear interest at the rate of
five percent per annum until the Company's obligation with respect to the
payment of such principal shall be discharged as provided in the Indenture
hereinafter mentioned.  Principal of and interest, if any, on this bond shall be
payable upon presentation hereof at the office or agency of the Company in
<PAGE>
 
Pittsburgh, Pennsylvania or at such other office or agency as may be designated
for such purpose by the Company from time to time.

     Any payment by the Company under its Indenture of Mortgage and Deed of
Trust, dated as of April 1, 1992, as supplemented (the "1992 Mortgage"), to
Mellon Bank, N.A., as trustee, of the principal of or interest, if any, on
securities which shall have been authenticated and delivered under the 1992
Mortgage on the basis of the issuance and delivery to such trustee of this bond
(other than by the application of the proceeds of a payment in respect of this
bond) shall, to the extent thereof, be deemed to satisfy and discharge the
obligation of the Company, if any, to make a payment of principal of or interest
on this bond, as the case may be, which is then due.

     This bond is one of a duly authorized issue of bonds of the Company, known
as its First Mortgage Bonds, unlimited in aggregate principal amount, of the
series and designation indicated above, which issue of bonds consists, or may
consist, of several series of varying denominations, dates and tenors, all
issued and to be issued under and equally secured (except insofar as a sinking
fund, or similar fund, established in accordance with the provisions of the
Indenture may afford additional security for the bonds of any specific series)
by a Trust Indenture dated as of August 1, 1947 executed by the Company to
Mellon Bank, N.A., formerly Mellon National Bank and Trust Company (herein
called the "Trustee"), as Trustee, as heretofore supplemented and amended (said
Trust Indenture as supplemented and amended being herein called the
"Indenture"), to which Indenture reference is hereby made for a description of
the property mortgaged and pledged, the nature and extent of the security, the
rights of the holders of the bonds as to such security, and the terms and
conditions upon which the bonds may be issued under the Indenture and are
secured.  The principal hereof may be declared or may become due on the
conditions, in the manner and at the time set forth in the Indenture, upon the
happening of a completed default as provided in the Indenture.  The Indenture
provides that such declaration may in certain events be waived by the holders of
a majority in principal amount of the bonds outstanding.

     With the consent of the Company and to the extent permitted by and as
provided in the Indenture, the rights and obligations of the Company and/or of
the holders of the bonds and/or the terms and provisions of the Indenture and/or
of any instruments supplemental thereto may be modified or altered by the
affirmative vote of the holders of at least seventy percent in principal amount
of the bonds then outstanding under the Indenture and any instruments
supplemental thereto (excluding bonds disqualified from voting by reason of the
interest of the Company or of certain related persons therein as provided in the
Indenture), and by the affirmative vote of at least seventy percent in principal
amount of the bonds of any series entitled to vote then outstanding under the
Indenture and any instruments supplemental thereto (excluding bonds disqualified
from voting as aforesaid) and affected by such modification or alteration, in
case one or more but less than all of the series of bonds then outstanding are
so affected; provided that no such modification or alteration shall permit the
extension of the 
<PAGE>
 
maturity of the principal of this bond or the reduction in the rate of interest
hereon or any other modification in the terms of payment of such principal or
interest or the taking of certain other action as more fully set forth in the
Indenture, without the consent of the holder hereof.


     The Company, the Trustee and any paying agent may deem and treat the person
in whose name this bond is registered as the absolute owner hereof for the
purpose of receiving payment of or on account of the principal hereof and
interest hereon and for all other purposes and shall not be affected by any
notice to the contrary.

     In the manner and with the effect provided in the Indenture, this bond may,
in whole at any time, or in part from time to time prior to maturity, be
redeemed by the Company with funds derived from any source by payment at the
office or agency of the Company in Pittsburgh, Pennsylvania or at such other
office or agency of the Company as shall be designated from time to time, at a
redemption price equal to 100% of the principal amount of this bond to be
redeemed.

     This bond is entitled to the benefits of, and is subject to call for
redemption for, the Sinking Fund, upon the notice, in the manner, and with the
effect provided in the Indenture by payment of the principal amount hereof.

     All bonds of this series shall be redeemed, at a redemption price equal to
100% of the principal amount thereof, if, and at such time as, the securities
which shall have been authenticated and delivered under the 1992 Mortgage on the
basis of the issuance and delivery to the trustee thereunder of the bonds of
this series shall have become subject to mandatory redemption.  The holder of
this bond, by its acceptance hereof, consents and agrees that no notice of such
redemption shall be required to be given.

     This bond shall initially be issued in the name of Mellon Bank, N.A.,
trustee under the 1992 Mortgage, and is not transferable except to any successor
trustee under the 1992 Mortgage.  Any such transfer shall be made as prescribed
in the Indenture by the registered holder hereof in person, or by such holder's
duly authorized attorney, at the office or agency of the Company in Pittsburgh,
Pennsylvania or at such other office or agency of the Company as shall be
designated from time to time, upon surrender and cancellation of this bond, and
thereupon a new bond or bonds of the same series and of authorized denominations
for a like aggregate principal amount, and having the same Original Issue Date
and Stated Maturity Date, will be issued to the transferee in exchange herefor
as provided in the Indenture.  Bonds of this series are interchangeable as to
denominations in the manner and upon the conditions prescribed in the Indenture.
No charge shall be made to any holder of any bond of this series for any
transfer or exchange of bonds except for any tax or taxes or other governmental
charge required to be paid in connection therewith.
<PAGE>
 
     No recourse shall be had for the payment of principal of or interest, if
any, on this bond, or any part thereof, or of any claim based hereon or in
respect hereof or of the Indenture, against any incorporator or any past,
present or future stockholder, officer or director of the Company or of any

                                   ARTICLE I
<PAGE>
 
                  FORM AND EXECUTION OF FIRST MORTGAGE BONDS,
                     POLLUTION CONTROL COLLATERAL SERIES H

     SECTION 1.01.  There is hereby created, for issuance under the Indenture
and to be secured thereby, a series of bonds, designated "First Mortgage Bonds,
Pollution Control Collateral Series H."  Each bond of such series shall bear the
descriptive title "First Mortgage Bond, Pollution Control Collateral Series H,"
and the form thereof shall be substantially of the tenor and purport
hereinbefore recited.  The bonds of the Forty-Seventh Series shall be issued
from time to time in an aggregate principal amount of $75,500,000, excluding any
bonds of the Forty-Seventh Series which may be authenticated in exchange for or
in lieu of or in substitution for or on transfer of other bonds of such series
pursuant to the provisions of the Indenture, and shall be issued as registered
bonds without coupons in denominations of $1,000 and integral multiples thereof.
The bonds of the Forty-Seventh Series shall mature on October 1, 2029 and shall
not bear interest except as provided in Article XIII of the Original Indenture.
The principal of and interest, if any, on each bond of the Forty-Seventh Series
shall be payable at the office or agency of the Company in Pittsburgh,
Pennsylvania or at such other office or agency of the Company as shall be
designated from time to time, in lawful money of the United States of America.

     Each bond of the Forty-Seventh Series shall be dated as of its Original
Issue Date.  The term "Original Issue Date" as used in this Section 1.01 shall
mean the date of the first authentication and delivery hereunder of such bonds.

     SECTION 1.02.  Each bond of the Forty-Seventh Series shall be redeemable at
the option of the Company in whole at any time, or in part from time to time,
prior to maturity, at a redemption price equal to 100.00% of the principal
amount thereof to be redeemed, by payment at the office or agency of the Company
in Pittsburgh, Pennsylvania, or at such other office or agency of the Company as
shall be designated from time to time.  Any such redemption shall be made upon
not less than 30 days' previous notice to be given in the manner provided in
Section 10.02 of the Original Indenture.

     SECTION 1.03.  The bonds of the Forty-Seventh Series shall be redeemable on
October 1 of each year commencing one year after the date of issuance of the
first bonds of said series for the Sinking Fund for bonds of said series
provided for in Article XII of the Original Indenture, upon not less than 30
days' previous notice of redemption to be given in the manner provided in
Section 10.02 of the Original Indenture, at the principal amount thereof.

     SECTION 1.04.  All bonds of the Forty-Seventh Series shall be redeemed, at
a redemption price equal to 100% of the principal amount thereof, if, and at
such time as, the securities which shall have been authenticated and delivered
under the 1992 Mortgage (as hereinafter defined) on the basis of the issuance
and delivery to the 1992 Mortgage Trustee (as hereinafter defined) of the bonds
of the Forty-Seventh Series shall have become subject to mandatory redemption.
No notice of such redemption shall be required to be given.
<PAGE>
 
     SECTION 1.05.  The bonds of the Forty-Seventh Series shall be issued and
delivered to Mellon Bank, N.A., as trustee under the Indenture of Mortgage and
Deed of Trust, dated as of April 1, 1992, as supplemented (the "1992 Mortgage"),
of the Company to such trustee (the "1992 Mortgage Trustee"), as the basis for
the authentication and delivery under the 1992 Mortgage of a series of
securities.  As provided in the 1992 Mortgage, the bonds of the Forty-Seventh
Series will be registered in the name of the 1992 Mortgage Trustee or its
nominee and will be owned and held by the 1992 Mortgage Trustee, subject to the
provisions of the 1992 Mortgage, for the benefit of the holders of all
securities from time to time outstanding under the 1992 Mortgage, and the
Company shall have no interest therein.

     Any payment by the Company under the 1992 Mortgage of the principal of or
interest, if any, on the securities which shall have been authenticated and
delivered under the 1992 Mortgage on the basis of the issuance and delivery to
the 1992 Mortgage Trustee of bonds of the Forty-Seventh Series (other than by
the application of the proceeds of a payment in respect of such bonds) shall, to
the extent thereof, be deemed to satisfy and discharge the obligation of the
Company, if any, to make a payment of principal of or interest on such bonds, as
the case may be, which is then due.

     The Trustee may conclusively presume that the obligation of the Company to
pay the principal of the bonds of the Forty-Seventh Series as the same shall
become due and payable shall have been fully satisfied and discharged unless and
until it shall have received a written notice from the 1992 Mortgage Trustee,
signed by an authorized officer thereof, stating that the principal of specified
bonds of the Forty-Seventh Series has become due and payable and has not been
fully paid, and specifying the amount of funds required to make such payment.

     SECTION 1.06.  The bonds of the Forty-Seventh Series shall not be
transferable, except to any successor trustee under said 1992 Mortgage.  Any
such transfer shall be made by the registered holder thereof, in person or by a
duly authorized attorney, at the office or agency of the Company in Pittsburgh,
Pennsylvania, or at such other office or agency of the Company as shall be
designated from time to time, upon surrender and cancellation of such bonds, and
thereupon a new bond or bonds of said series and of authorized denominations for
a like aggregate principal amount and having the same Original Issue Date,
Stated Maturity Date and other terms and conditions will be issued to the
transferee in exchange therefor.  New bonds issued upon any such transfer shall
be so dated and shall carry such rights to any interest accrued and unpaid that
neither gain nor loss in interest shall result from such transfer.

     SECTION 1.07.  The registered holder of any bond or bonds of the Forty-
Seventh Series at his option may surrender the same at the office or agency of
the Company in Pittsburgh, Pennsylvania, or at such other office or agency of
the Company as shall be designated from time to time, for cancellation in
exchange for another or other bonds of the said series of authorized
denominations, but of the same aggregate principal amount and 
<PAGE>
 
having the same Original Issue Date, Stated Maturity Date and other terms and
conditions and being so dated and carrying such rights to any interest accrued
and unpaid that neither gain nor loss in interest shall result from such
exchange. Thereupon, the Company shall execute and deliver to the Trustee, and
the Trustee shall authenticate and deliver such other bond or bonds to such
registered holder either at its office or at said office or agency of the
Company.

     SECTION 1.08.  No charge shall be made to any registered holder of any bond
of the Forty-Seventh Series for any exchange or transfer of bonds of said series
except that in case of any exchange or transfer the Company may make a charge
therefor sufficient to reimburse it for any tax or taxes or other governmental
charge required to be paid in connection therewith.

     SECTION 1.09.  For the purpose only of complying with the Original
Indenture (particularly Sections 10.02 and 12.02(b) thereof) in connection with
the redemption of bonds of the Forty-Seventh Series, for each $1,000 principal
amount of bonds authenticated and delivered hereunder there shall be assigned a
number in such manner and at such time as the Trustee may deem appropriate.
Portions of the principal amount less than the entire principal amount of a bond
of the Forty-Seventh Series of a denomination larger than $1,000 may be redeemed
only in integral multiples of $1,000.

                                  ARTICLE II

                                 MISCELLANEOUS

     SECTION 2.01.  The holders of the bonds of the Forty-Seventh Series shall
be deemed to have consented and agreed that the Company may, but shall not be
obligated to, fix a record date for the purpose of determining the holders of
the bonds of the Forty-Seventh Series entitled to consent to any amendment or
supplement to the Indenture or the waiver of any provision thereof or any act to
be performed thereunder.  If a record date is fixed, those persons who were
holders at such record date (or their duly designated proxies), and only those
persons, shall be entitled to consent to such amendment, supplement or waiver or
to revoke any consent previously given, whether or not such persons continue to
be holders after such record date.  No such consent shall be valid or effective
for more than 90 days after such record date.

     SECTION 2.02.  The recitals of fact herein and in the bonds (except the
Trustee's Certificate) shall be taken as statements of the Company and shall not
be construed as made or warranted by the Trustee.  The Trustee makes no
representations as to the value of any of the property subjected to the lien of
the Indenture, or any part thereof, or as to the title of the Company thereto,
or as to the security afforded thereby and hereby, or as to the validity of this
Ninetieth Supplemental Trust Indenture or of the bonds of the Forty-Seventh
Series (except the Trustee's Certificate), and the Trustee shall incur no
responsibility in respect of such matters.
<PAGE>
 
     SECTION 2.03.  This Ninetieth Supplemental Trust Indenture shall be
construed in connection with and as part of the Indenture.

     SECTION 2.04.  (a)  If any provision of this Ninetieth Supplemental Trust
Indenture limits, qualifies, or conflicts with another provision of the
Indenture required to be included in indentures qualified under the Trust
Indenture Act of 1939 (as in force at the date of this Ninetieth Supplemental
Trust Indenture) by any of the provisions of Sections 310 to 317, inclusive, of
said Act, such required provision shall control.

     (b)  In case any one or more of the provisions contained in this Ninetieth
Supplemental Trust Indenture or in the bonds issued hereunder should be invalid,
illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein and therein shall
not in any way be affected, impaired, prejudiced or disturbed thereby.

     SECTION 2.05.  Whenever in this Ninetieth Supplemental Trust Indenture
either of the parties hereto is named or referred to, this shall be deemed to
include the successors or assigns of such party, and all the covenants and
agreements in this Ninetieth Supplemental Trust Indenture contained by or on
behalf of the Company or by or on behalf of the Trustee shall bind and inure to
the benefit of the respective successors and assigns of such parties, whether so
expressed or not.

     SECTION 2.06.  This Ninetieth Supplemental Trust Indenture may be
simultaneously executed in several counterparts, and all said counterparts
executed and delivered, each as an original, shall constitute but one and the
same instrument.

     The Table of Contents and the descriptive headings of the several Articles
of this Ninetieth Supplemental Trust Indenture were formulated, used and
inserted herein for convenience only and shall not be deemed to affect the
meaning or construction of any of the provisions hereof.

     SECTION 2.07.  Duquesne Light Company does hereby constitute and appoint
Diane S. Eismont to be its attorney for it and in its name and as and for its
corporate deed to acknowledge this Ninetieth Supplemental Trust Indenture before
any person having authority by law to take such acknowledgment.

     Mellon Bank, N.A. does hereby constitute and appoint D.M. Babich to be its
attorney-in-fact for it and in its name and as and for its corporate deed to
acknowledge this Ninetieth Supplemental Trust Indenture before any person having

acquired by the Company, it being the intention of the Company that all such
property acquired by the Company after the date of the execution and delivery of
this Supplemental Indenture No. 8 shall be as fully embraced within and
subjected to the Lien hereof as if such property were owned by the Company as of
the date of the execution and delivery of this Supplemental Indenture No. 8;

                            Granting Clause Fourth

     All other property of whatever kind and nature subjected or intended to be
subjected to the Lien of the Mortgage by any of the terms and provisions
thereof;

                               Excepted Property

     Expressly excepting and excluding, however, from the Lien and operation of
the Mortgage all Excepted Property of the Company, whether now owned or
hereafter acquired;

     TO HAVE AND TO HOLD all such property, real, personal and mixed, unto the
Trustee forever;

     SUBJECT, HOWEVER, to Permitted Liens and to Liens which have been granted

was at the date of execution and delivery of the Original Indenture or
thereafter became or hereafter becomes subject to the Lien of any Class "A"
Mortgage, the Lien of the Mortgage shall at all times be junior and subordinate
to the Lien of such Class "A" Mortgage;

     IN TRUST, NEVERTHELESS, for the equal and proportionate benefit and
security of the Holders from time to time of all Outstanding Securities without
any priority of any such Security over any other such Security;

     PROVIDED, HOWEVER, that if, after the right, title and interest of the
Trustee in and to the Mortgaged Property shall have ceased, terminated and
become void in accordance with Article Nine of the Original Indenture, the
principal of and premium, if any, and interest, if any, on the Securities shall
have been paid to the Holders thereof, or shall have been paid to the Company
pursuant to Section 603 of the Original Indenture, then and in that case the
Mortgage and the estate and rights thereby granted shall cease, terminate and be
void, and

                                      -3-
<PAGE>
 
the Trustee shall cancel and discharge the Mortgage and execute and deliver to
the Company such instruments as the Company shall require to evidence the
discharge thereof; otherwise the Mortgage shall be and remain in full force and
effect; and

     THE PARTIES HEREBY FURTHER COVENANT AND AGREE that this Supplemental
Indenture No. 8 is a supplement to the Mortgage. As supplemented by this
Supplemental Indenture No. 8, the Mortgage is in all respects ratified, approved
and confirmed, and the Mortgage and this Supplemental Indenture No. 8 shall
together constitute one and the same instrument.

     IN WITNESS WHEREOF, the parties have caused this Supplemental Indenture No.
8 to be duly executed, and their respective corporate seals to be affixed and
attested, all as of the day and year first above written.

sometimes called "Series No. 7."

     The Company has duly authorized the execution and delivery of this
Supplemental Indenture No. 9 to establish the Securities of Series No. 7 and has
duly authorized the issuance of such Securities; and all acts necessary to make
this Supplemental Indenture No. 9 a valid agreement of the Company, and to make

     NOW, THEREFORE, THIS SUPPLEMENTAL INDENTURE NO. 9 WITNESSETH, that, in

premium, if any, and interest, if any, on all Securities from time to time
Outstanding and the performance of the covenants contained therein and in the
Mortgage and to declare the terms and conditions on which such Securities are
secured, the Company hereby grants, bargains, sells, releases, conveys, assigns,
transfers, mortgages, pledges, sets over and confirms to the Trustee, and grants
to the Trustee a security interest in, the following:

                             GRANTING CLAUSE FIRST

     All right, title and interest of the Company in and to property (other than
Excepted Property), real, personal and mixed and wherever situated, in any case

                             GRANTING CLAUSE SECOND

     Subject to the applicable exceptions permitted by Section 810, Section 1303
and Section 1305 of the Original Indenture, all property (other than Excepted
Property) of the kind and nature described in Granting Clause First which may be
hereafter acquired by the Company, it being the intention of the Company that
all such property acquired by the Company after the date of the execution and
delivery of this Supplemental Indenture No. 9 shall be as fully embraced within
and subjected to the Lien hereof as if such property were owned by the Company
as of the date of the execution and delivery of this Supplemental Indenture No.
9;


                             GRANTING CLAUSE FOURTH

     All other property of whatever kind and nature subjected or intended to be
subjected to the Lien of the Mortgage by any of the terms and provisions
thereof;

                               EXCEPTED PROPERTY

     Expressly excepting and excluding, however, from the Lien and operation of
the Mortgage all Excepted Property of the Company, whether now owned or
hereafter acquired;

     TO HAVE AND TO HOLD all such property, real, personal and mixed, unto the
Trustee forever;

     SUBJECT, HOWEVER, to Permitted Liens and to Liens which have been granted

after the date of execution and delivery of the Original Indenture, to vendors'
Liens, purchase money mortgages and other Liens thereon at the time of the

Mortgage), it being understood that with respect to any of such property which
was at the date of execution and delivery of the Original Indenture or
thereafter became or hereafter becomes subject to the Lien of any Class "A"
Mortgage, the Lien of the Mortgage shall at all times be junior and subordinate
to the Lien of such Class "A" Mortgage;

     IN TRUST, NEVERTHELESS, for the equal and proportionate benefit and
security of the Holders from time to time of all Outstanding Securities without
any priority of any such Security over any other such Security;

     PROVIDED, HOWEVER, that if, after the right, title and interest of the
Trustee in and to the Mortgaged Property shall have 
<PAGE>
 
ceased, terminated and become void in accordance with Article Nine of the
Original Indenture, the principal of and premium, if any, and interest, if any,
on the Securities shall have been paid to the Holders thereof, or shall have
been paid to the Company pursuant to Section 603 of the Original Indenture, then
and in that case the Mortgage and the estate and rights thereby granted shall
cease, terminate and be void, and the Trustee shall cancel and discharge the
Mortgage and execute and deliver to the Company such instruments as the Company
shall require to evidence the discharge thereof; otherwise the Mortgage shall be
and remain in full force and effect; and

     THE PARTIES HEREBY FURTHER COVENANT AND AGREE as follows:

                                ARTICLE ONE

                       SEVENTH SERIES OF SECURITIES

     There is hereby created a series of Securities designated "First Collateral
Trust Bonds, Pollution Control Series H" and limited in aggregate principal

established in an Officer's Certificate.

                                ARTICLE TWO

                          MISCELLANEOUS PROVISIONS

Reconciliation Act of 1993 (Pub. L. No. 103-66) ("Budget Reconciliation Act")
the marginal Federal income tax rate applicable to corporations increased from
34 percent to 35 percent for tax years beginning on or after January 1, 1993

Basic Rent, Casualty Values, Special Casualty Values, Modified Special Casualty
Values and Special Termination Values pursuant to Sections 3(d) and 3(f) of the
Facility Lease.
 
          NOW, THEREFORE, intending to be legally bound hereby, in consideration

results in the marginal Federal income tax rate applicable to corporations
differing from the rate assumed to be applicable in the Pricing Assumptions as

Reconciliation Act of 1993 (Pub. L. No. 103-66) ("Budget Reconciliation Act")
the marginal Federal income tax rate applicable to corporations increased from
34 percent to 35 percent for tax years beginning on or after January 1, 1993

Basic Rent, Casualty Values, Special Casualty Values, Modified Special Casualty
Values and Special Termination Values pursuant to Sections 3(d) and 3(f) of the
Facility Lease.

          NOW, THEREFORE, intending to be legally bound hereby, in consideration

          AMENDMENT NO. 2 dated as of October 13, 1994, to the Tax
Indemnification Agreement dated as of September 15, 1987, between Beaver Valley
Leasing Corporation (the "Owner Participant") and Duquesne Light Company (the
"Lessee"), as amended.

                                  WITNESSETH:

          WHEREAS, the Owner Participant and the Lessee have entered into the
Participation Agreement (such term and other capitalized terms used herein
without definition being defined as provided in Section 1);

          WHEREAS, the Lessor and the Lessee have entered into the Facility
Lease providing for the lease by the Lessor to the Lessee of the Undivided

          WHEREAS, the Owner Participant and the Lessee have heretofore entered
into a Tax Indemnification Agreement dated as of September 15, 1987 (the "Tax

November 15, 1992, setting forth the rights and obligations of the Owner
Participant and the Lessee with respect to those items of income, gain, loss,

an owner of property;

          WHEREAS, pursuant to Section 3(d) of the Facility Lease, the Schedules
of Basic Rent, Casualty Values, Special Casualty Values, Special Modified

Omnibus Budget Reconciliation Act of 1993 (Pub. L. No. 103-66) and, in
connection with such modifications, the Lessee and the Owner Participant desire
to amend the Tax Indemnification Agreement in certain respects.

          NOW, THEREFORE, in consideration of the premises and of other good and
valuable consideration, receipt of which is hereby acknowledged, the parties
hereto agree as follows:

               Participant's gross income) pursuant to Section 6(a) of Amendment
               No. 4 to Participation Agreement dated the date hereof, computed

           (ii)   INTEREST PERIODS.  Subject to the other requirements of this
      subsection (e), the Company may from time to time elect to have the
      interest on all Advances comprising part of the same Borrowing determined
      and payable for a specified period (an "INTEREST PERIOD" for such
      Advances) in accordance with paragraph (iii), below.  The first day of an
      Interest Period for such Advances shall be the date such Advance is most
      recently Converted, which shall be a Business Day.  All Interest Periods
      shall end on or prior to the Final Maturity Date.  Any Interest Period for
      an Advance that would otherwise end after the Final Maturity Date or
      earlier date for the repayment of such Advance shall be deemed to end on
      the Final Maturity Date or such earlier repayment date, as the case may
      be.


           (iii)  EURODOLLAR RATE.  Subject to the requirements of this
      subsection (e) and subsection (f), below, the Company may from time to
      time elect to have any Advances comprising part of the same Borrowing
      Converted to Eurodollar Rate Advances. The Interest Period applicable to
      such Eurodollar Rate Advances shall be of one, two, three or six whole
      months' duration, as the Company shall select in its notice delivered to
      Union Bank pursuant to subsection (f), below. If the Company shall have
      made such election, the Company shall pay interest on such
<PAGE>
 
                                                                              22

      Eurodollar Rate Advances at the Eurodollar Rate, for the applicable
      Interest Period for such Eurodollar Rate Advances, which interest shall be
      payable on the last day of such Interest Period except, to the extent such
      Interest Period is of six whole months' duration, interest shall also be
      payable with respect to such Interest Period on the three whole month
      anniversary of the commencement of such Interest Period, and, in any case,
      on the date for repayment or prepayment for such Eurodollar Rate Advances.
      Any Interest Period pertaining to Eurodollar Rate Advances that begins on
      the last Business Day of a calendar month (or on a day for which there is
      no numerically corresponding day in the calendar month at the end of such
      Interest Period) (A) shall end on the last Business Day of a calendar
      month and (B) with respect to any such Interest Period of six whole
      months' duration, interest not payable on the last day of an Interest
      Period shall also be payable on the last Business Day of a calendar month.

           (iv)   INTEREST RATE DETERMINATIONS.  Union Bank shall give prompt
      notice to the Company and the Participating Banks of the Eurodollar Rate
      determined from time to time by Union Bank to be applicable to each
      Eurodollar Rate Advance.

      (f)  CONVERSION OF ADVANCES.  The Company may elect to Convert one or more
Advances of any Type to one or more Advances of the same or any other Type on
the following terms and subject to the following conditions:

           (i)    Each Conversion shall be made as to all Advances comprising a
      single Borrowing upon written notice given by the Company to Union Bank
      not later than 10:00 a.m. (Los Angeles time) on the third Business Day
      prior to the date of the proposed Conversion. Union Bank shall notify each
      Participating Bank of the contents of such notice promptly after receipt
      thereof. Each such notice shall specify therein the following information:
      (A) the date of such proposed Conversion (which in the case of Eurodollar
      Rate Advances shall be the last day of the Interest Period then applicable
      to such Advances to be Converted), (B) the Type of, and Interest Period,
      if any, applicable to the Advances proposed to be Converted, (C) the
      aggregate principal amount of Advances proposed to be Converted, and (D)
      the Type of Advances to which such Advances are proposed to be Converted
      and the Interest Period, if any, to be applicable thereto.
           


           (ii)   During the continuance of a Reimbursement Default (other than
      a Reimbursement Event of Default), the right of the Company to Convert
      Advances to Eurodollar Rate Advances shall be suspended, and all
      Eurodollar Rate Advances then outstanding
<PAGE>
 
                                                                              23

      shall be Converted to Reference Rate Advances on the last day of the
      Interest Period then in effect, if, on such day, a Reimbursement Default
      (other than a Reimbursement Event of Default) shall be continuing.

           (iii)  During the continuance of a Reimbursement Event of Default,
      the right of the Company to Convert Advances to Eurodollar Rate Advances
      shall be suspended, and upon the occurrence of a Reimbursement Event of
      Default, all Eurodollar Rate Advances then outstanding shall immediately,
      without further act by the Company, be Converted to Reference Rate
      Advances.

           (iv)   If no notice of Conversion is received by Union Bank as
      provided in paragraph (i), above, with respect to any outstanding
      Eurodollar Rate Advances on or before the third Business Day prior to the
      last day of the Interest Period then in effect for such Eurodollar Rate
      Advances, Union Bank shall treat such absence of notice as a deemed notice
      of Conversion providing for such Advances to be Converted to Reference
      Rate Advances on the last day of such Interest Period.

      (g)  OTHER TERMS RELATING TO THE MAKING AND CONVERSION OF ADVANCES.  (i)
Notwithstanding anything in subsections (c), (e) and (f), above, to the
contrary:

                  (A)  at no time shall more than seven different Borrowings be

           (ii)   Each notice of Conversion pursuant to subsection (f), above,
      shall be irrevocable and binding on the Company.

           (iii)  Each Reference Bank agrees to furnish to Union Bank timely
      information for the purpose of determining the Eurodollar Rate for each
      Interest Period.  If any one or more of the Reference Banks shall not
      furnish such timely information to Union Bank for the purpose of
      determining any such interest rate, Union Bank shall determine such
      interest rate on the basis of timely information furnished by the
      remaining Reference Banks.

      days from the date of making such DLE Term Advance, (B) upon the

           (ii)   The Company may, (A) upon at least two Business Days' notice
      to Union Bank, in the case of any Eurodollar Rate Advance, and (B) upon at
      least one Business Day's notice to Union Bank, in the case of any
      Reference Rate Advance, in each case stating the proposed date and

      to be prepaid, and if such notice is given, the Company shall, prepay, in
      whole or ratably in part, together with accrued interest to the date of
      such prepayment on the principal amount prepaid and any amounts due
      pursuant to Section 4(c) hereof, the outstanding principal amount of all
      Advances comprising the same Borrowing, in each case as the Company shall
      designate in such notice; provided, however, that each partial prepayment
      shall be in an aggregate principal amount not less than $1,000,000, or, if
      less, the aggregate principal amount of all Advances then outstanding.


      (j)  DEFAULT INTEREST.  Any amounts payable by the Company hereunder that
are not paid when due shall (to the fullest extent permitted by law) bear
interest, from the date when due until paid in full, at the Default Rate,
payable on demand.

      (k)  EVIDENCE OF INDEBTEDNESS.  The LOC Bank and each Participating Bank
shall maintain, in accordance with their usual practice, an account or accounts

Participation Percentage and (iii) the Maximum Credit Amount applicable to such
Letters of Credit, in each case from and including the Date of Issuance thereof

<PAGE>
 
                                                                              26

payable quarterly in arrears on the first day of each March, June, September and
December, commencing December 1, 1994; provided, however, that the percentage
set forth in clause (i), above, shall be decreased to 0.53% in the event that,
and at all times during which, the First Mortgage Bonds are rated A3 and A- (or
the then current equivalents) or higher by both Moody's and S&P, respectively
(or, in the event that Moody's or S&P shall cease to be in the business of
issuing ratings of debt, such other nationally recognized rating agency mutually
acceptable to the Required Banks and the Company), to be effective on the first
date on which both such ratings shall have been issued by Moody's and S&P (or
such other rating agency); and provided further, however, that the percentage
set forth in clause (i), above, shall be increased to 0.88% in the event that,
and at all times during which, the First Mortgage Bonds are rated below Baa3 and
BBB- (or the then current equivalents) by both Moody's and S&P, respectively
(or, in the event that Moody's or S&P shall cease to be in the business of
issuing ratings of debt, such other nationally recognized rating agency mutually
acceptable to the Required Banks and the Company), to be effective on the first
date on which both such ratings shall have been issued by Moody's and S&P (or
such other rating agency). Upon receipt from the Company of fees payable in
accordance with the provisions of this subsection (a), Union Bank agrees to pay,
to the account of each Participating Bank as soon as practicable but in no event
later than the next succeeding Business Day and in accordance with Section 6(a)
hereof, the fees paid to it for the account of such Participating Bank pursuant
to this subsection (a).

      (b)  In addition to the fees provided for in subsection (a), above, the
Company shall pay to Union Bank, for the account of each Participating Bank,
such other fees as are provided for in that certain letter agreement between the
Company and Union Bank (the "FEE LETTER") entered into separately herefrom and
dated the Date of Issuance.

      (c)  The Company agrees to pay to the LOC Bank, the Administrating Banks
and the Participating Banks, for their respective accounts, fees, in such
amounts and payable at such times, as shall be agreed in writing by or among
themselves.

      SECTION 4. CHANGE IN CIRCUMSTANCES; YIELD PROTECTION.

      (a)  CHANGE IN CIRCUMSTANCES.  If, after the date hereof, any Bank shall
have determined that the adoption of any Applicable Law, any change therein or
any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by such Bank with any request or directive
(whether or not having the force of law) of any such
<PAGE>
 
                                                                              27

authority, central bank or comparable agency, shall (i) impose, modify or deem
applicable any reserve, special deposit, insurance assessment, capital adequacy
or similar requirement (including, without limitation, any such requirement
imposed by the Board of Governors of the Federal Reserve System) against letters
of credit (or participatory interests therein) issued by, or assets held by,
Advances made by, or deposits in or for the account of, the LOC Bank or any
Participating Bank or any holding company of any thereof or (ii) impose on the
LOC Bank or any Participating Bank any other condition regarding this Agreement,
the Letters of Credit or participating interests therein or the Advances or
(iii) change the basis of taxation of payments to any Participating Bank of the
principal of or interest on any Eurodollar Rate Advance made by such
Participating Bank or any fees or other amounts payable hereunder (other than
changes in respect of taxes imposed on the overall net income of such
Participating Bank, or its Applicable Lending Office, by any jurisdiction in
which the Participating Bank has an office or by any political subdivision or
taxing authority therein) and the result of any event referred to in clause (i),
(ii) or (iii) of this subsection (a) shall be (A) to increase the cost to the
LOC Bank and/or any Participating Bank and/or any holding company thereof of
issuing or maintaining any of the Letters of Credit or commitments or
participatory interests therein or agreeing to make, making or maintaining the
Advances or (B) to reduce the LOC Bank's or any Participating Bank's return on
capital with respect thereto to a level below that which the LOC Bank or such
Participating Bank could have achieved but for such adoption, change or
compliance (taking into consideration the LOC Bank's or such Participating
Bank's, as the case may be, policies with respect to capital adequacy) by an
amount deemed by the LOC Bank or such Participating Bank, as the case may be, to
be material (which increase in cost pursuant to clause (A), above, or reduction
of return pursuant to clause (B), above, shall be calculated in accordance with
the LOC Bank's or any Participating Bank's, as the case may be, reasonable
allocation of the aggregate of such cost increases or capital resulting from
such events), then, within 15 days after demand by the LOC Bank or such
Participating Bank, as the case may be, the Company shall pay to the LOC Bank or
such Participating Bank, as the case may be, all additional amounts that are
necessary to compensate the LOC Bank or such Participating Bank, as the case may
be, for such increase in cost or reduction of return incurred by the LOC Bank or
such Participating Bank, as the case may be. Each of the LOC Bank and the
Participating Banks agree that it shall designate a different Applicable Lending
Office if such designation will avoid the need for, or reduce the amount of,
such increased costs or reduction of return and will not, in the sole opinion of
the LOC Bank or such Participating Bank, as the case may be, cause the LOC Bank
or such Participating Bank, as the case may be, to suffer any economic loss or
legal or regulatory disadvantage.

                                                                              28

      (b)  EURODOLLAR RESERVES.  The Company shall pay to each Participating
Bank upon demand, so long as such Participating Bank shall be required under
regulations of the Board of Governors of the Federal Reserve System to maintain
reserves with respect to liabilities or assets consisting of or including
Eurocurrency Liabilities, additional interest on the unpaid principal amount of
such Participating Bank's portion of each Eurodollar Rate Advance, from the date
of such Advance until such principal amount is paid in full, at an interest rate
per annum equal at all times to the remainder obtained by subtracting (i) the
rate described in clause (i) of the definition of "Eurodollar Rate" for the
Interest Period for such Advance from (ii) the rate obtained by dividing such
rate by a percentage equal to 100% minus the Eurodollar Reserve Percentage of
such Participating Bank for such Interest Period. Such additional interest shall
be determined by such Participating Bank and notified to the Company and the
Administrating Banks.

      (c)  BREAKAGE INDEMNITY.  The Company shall indemnify each Participating
Bank against any loss, cost or reasonable expense which such Participating Bank
may sustain or incur as a consequence of (i) any failure by the Company to
Convert any Advance hereunder after irrevocable notice of Conversion has been
given pursuant to Section 2(f) hereof, (ii) any payment, prepayment or
Conversion of a Eurodollar Rate Advance required or permitted by any other
provision of this Agreement (other than pursuant to subsection (h), below) or
otherwise made or deemed made on a date other than the last day of the Interest
Period applicable thereto, (iii) any default in payment or prepayment of the
principal amount of any Advance or any part thereof or interest accrued thereon,
as and when due and payable (at the due date thereof, by irrevocable notice of
prepayment or otherwise) or (iv) any Conversion pursuant to Section 2(f)(iii)
caused by the occurrence of any Reimbursement Event of Default. Such loss, cost
or reasonable expense shall include an amount equal to the excess, if any, as
reasonably determined by such Participating Bank, of (A) its cost of obtaining
the funds for the Advance being paid, prepaid or Converted (based on the
Eurodollar Rate) for the period from the date of such payment, prepayment or
Conversion to the last day of the Interest Period for such Advance over (B) the
amount of interest (as reasonably determined by such Participating Bank) that
would be realized by such Participating Bank in reemploying the funds so paid,
prepaid or Converted for such period or Interest Period, as the case may be. For
purposes of this subsection (c), it shall be presumed that each Participating
Bank shall have funded each such Advance with a fixed-rate instrument bearing
the rates and maturities designated in the determination of the applicable
interest rate for such Advance.

      (d)  TAXES.  All payments made by the Company to the LOC Bank, Union Bank
or any other Bank under this Agreement shall be made free and 
<PAGE>
 
                                                                              29

clear of, and without reduction for or on account of, any stamp or other taxes,
levies, imposts, duties, charges, fees, deductions, withholdings, restrictions
or conditions of any nature whatsoever hereafter imposed, levied, collected,
withheld or assessed by any country (or by any political subdivision or taxing
authority thereof or therein), except for franchise taxes and changes in the
rate of tax on the overall net income of the LOC Bank, Union Bank and the other
Banks (such nonexcluded taxes being called "TAX" or "TAXES"). If any Taxes are
required to be withheld from any amounts payable by the Company to the LOC Bank,
Union Bank or any other Bank, the amounts so payable shall be increased to the
extent necessary to yield to the LOC Bank, Union Bank or such other Bank, as the
case may be (after payment of all Taxes), interest or any other amounts payable
hereunder at the rates or in the amounts specified in this Agreement; provided
that the Company shall not be obligated to pay such amounts for the benefit of
the LOC Bank, Union Bank or any other Bank with respect to any period in which
the LOC Bank, Union Bank or such other Bank, as the case may be, has failed (x)
to file any form or certificate that it was entitled to file that would have
exempted the LOC Bank, Union Bank or such other Bank, as the case may be, from
such Taxes or (y) to take other action that would entitle the LOC Bank, Union
Bank or such other Bank, as the case may be, to an exemption from such Taxes, if
such action would not, in the reasonable judgment of the LOC Bank, Union Bank or
such other Bank, as the case may be, be otherwise disadvantageous to it.
Whenever any Tax is payable by the Company, as promptly as possible thereafter
the Company shall send the LOC Bank, Union Bank or any other Bank, as the case
may be, a receipt or other evidence of payment thereof.

      (e)  BASIS FOR CLAIMS FOR COMPENSATION. No law, rule or regulation in the
form in which it is in effect on the date hereof, but excluding changes in the
interpretation or administration thereof after the date hereof, or Tax to which
the LOC Bank, Union Bank or any other Bank is subject on the date hereof, shall
be used as the basis of a claim for compensation pursuant to subsections (a) and
(d), above, by the LOC Bank, Union Bank or such other Bank, as the case may be.

      (f)  PARTICIPATING BANKS AND PARTICIPANTS. The Company agrees that each
Participant shall have the same rights and obligations under this Section 4 with
respect to its respective participation to the same extent as if such
Participant were named instead of the LOC Bank in this Section 4.
Notwithstanding the foregoing, any payment to be made by the Company to a
Participating Bank or a Participant pursuant to subsection (a), above, shall be
paid to Union Bank for the account of such Participating Bank or Participant, as
the case may be.
<PAGE>
 
                                                                              30

      (g)  NOTICES.  A certificate as to the nature of any occurrence giving
rise to, and the calculation of, compensation to, and a statement setting forth
in reasonable detail the method by which such compensation has been calculated
by, the LOC Bank, Union Bank, a Participating Bank or a Participant pursuant to
subsection (a), (b), (c) or (d) of this Section 4 shall be submitted by the LOC
Bank, Union Bank, such Participating Bank or such Participant, as the case may
be, to the Company (together with notification to Union Bank of the amount of
such compensation). Such certificate shall be conclusive (absent demonstrable
error) as to the amount thereof. Each such certificate shall identify the LOC
Bank, Union Bank, such Participating Bank or such Participant, as the case may
be, as the party concerned. Upon the reasonable request of the Company, the LOC
Bank, Union Bank, such Participating Bank or such Participant, as the case may
be, shall provide the Company an estimate of the total additional compensation
that would be payable to the LOC Bank, Union Bank, such Participating Bank or
such Participant, as the case may be, on an annual basis.

      (h)  CHANGE IN LEGALITY.  Notwithstanding any other provision herein, if
the adoption of or any change in any law or regulation or in the interpretation
or administration thereof by any governmental authority charged with the
administration or interpretation thereof shall make it unlawful for any
Participating Bank to make or maintain any Eurodollar Rate Advance or to give
effect to its obligations as contemplated hereby with respect to any Eurodollar
Rate Advance, then, by written notice to the Company and Union Bank, such
Participating Bank may:

           (i)    declare that Eurodollar Rate Advances shall not thereafter be
      made by such Participating Bank hereunder, whereupon the right of the
      Company to select Eurodollar Rate Advances for any Advance or Conversion
      shall be forthwith suspended until such Participating Bank shall withdraw
      such notice as provided below or shall cease to be a Participating Bank
      hereunder; and

           (ii)   require that all outstanding Eurodollar Rate Advances be
      Converted to Reference Rate Advances, in which event all Eurodollar Rate
      Advances shall be automatically Converted to Reference Rate Advances as of
      the effective date of such notice as provided below.

Upon receipt of any such notice, Union Bank shall promptly notify the
Participating Banks thereof. Promptly upon becoming aware that the circumstances
that caused such Participating Bank to deliver such notice no longer exist, such
Participating Bank shall deliver notice thereof to the Company and Union Bank
withdrawing such prior notice (but the failure to
<PAGE>
 
                                                                              31

do so shall impose no liability upon such Participating Bank). Promptly upon
receipt of such withdrawing notice from such Participating Bank, Union Bank
shall deliver notice thereof to the Company and the Participating Banks and such
suspension shall terminate. Prior to any Participating Bank giving notice to the
Company under this subsection (h), such Participating Bank shall use reasonable
efforts to change the jurisdiction of its Applicable Lending Office, if such
change would avoid such unlawfulness and would not, in the sole determination of
such Participating Bank, be otherwise disadvantageous to such Participating
Bank. Any notice to the Company by any Participating Bank shall be effective as
to each Eurodollar Rate Advance on the last day of the Interest Period currently
applicable to such Eurodollar Rate Advance; provided that if such notice shall
state that the maintenance of such Advance until such last day would be
unlawful, such notice shall be effective as to each Eurodollar Rate Advance of
such Participating Bank (but not the other Participating Banks) on the date of
receipt by the Company and Union Bank.

      (i)  MARKET RATE DISRUPTIONS.  If, (i) Union Bank determines that an
adequate basis does not exist for the determination of the Eurodollar Rate for
Eurodollar Rate Advances or (ii) if the Required Banks shall notify Union Bank
that the Eurodollar Rate shall not adequately reflect the cost to such Required
Banks of making, funding or maintaining their respective Eurodollar Rate
Advances, the right of the Company to select or receive or Convert into such
Type of Advances shall be forthwith suspended until Union Bank shall notify the
Company and the Participating Banks that the circumstances causing such
suspension no longer exist, and until such notification from Union Bank, each
request for or Conversion into such Type of Advance hereunder shall be deemed to
be a request for or Conversion into Reference Rate Advances.

      SECTION 5. PARTICIPATIONS.

      (a)  By the issuance of a Letter of Credit and without any further action
on the part of the LOC Bank or any Participating Bank in respect thereof, the
LOC Bank shall hereby be deemed to have granted to each Participating Bank, and
each Participating Bank shall hereby be deemed to have acquired from the LOC
Bank, an undivided interest and participation in such Letter of Credit
(including any letter of credit issued by the LOC Bank in substitution or
exchange for such Letter of Credit pursuant to the terms thereof), and in the
LOC Bank's rights and obligations with respect thereto, equal to such
Participating Bank's Participation Percentage of the Maximum Credit Amount of
such Letter of Credit, effective upon the issuance of such Letter of Credit.  In
consideration and in furtherance of the foregoing, each Participating Bank
hereby absolutely and unconditionally agrees to pay to the LOC Bank, in
accordance with this Section 5, such

                                                                              32

Participating Bank's Participation Percentage of each payment made by the LOC
Bank of a draft under each Letter of Credit. Upon receipt of a draft and
certificate under a Letter of Credit on any Business Day, the LOC Bank shall
give telephonic notice to the Company no later than 10:00 a.m., New York City
time, and, if the Company has not reimbursed the LOC Bank on or prior to 1:00
p.m., New York City time, on the day upon which the LOC Bank has made payment
with respect thereto, to each Participating Bank no later than 2:30 p.m., New
York City time, with respect to any draft and certificate received before 9:05
a.m., New York City time, on the same Business Day, and, with respect to any
draft and certificate received at or after 9:05 a.m., New York City time, on the
next succeeding Business Day (to be followed in either case by delivery by telex
or telecopy of a Notice of Drawing), of the amount of the payment to be made by
the LOC Bank pursuant to such draft and certificate and, with respect to each
Participating Bank, the dollar amount of such Participating Bank's Participation
Percentage thereof. If such telephonic notice is received by a Participating
Bank after 2:30 p.m., New York City time, on any Business Day, such notice shall
be deemed to have been received on the next succeeding Business Day. With
respect to each Participating Bank, promptly upon receipt of such telephonic
notice from the LOC Bank but in any event no later than the same Business Day on
which such telephonic notice was received, or deemed to have been received, from
the LOC Bank, such Participating Bank shall pay to the LOC Bank an amount equal
to the product of (A) such Participating Bank's Participation Percentage and (B)
the amount of the payment made or to be made by the LOC Bank on such draft;
provided, however, that, with respect to the payment of any draw on a Letter of
Credit, the LOC Bank shall not require such Participating Bank to pay (exclusive
of interest) an amount greater than the product of (x) such Participating Bank's
Participation Percentage and (y) the lesser of (1) the Maximum Available Credit
Amount of such Letter of Credit immediately prior to adjustment for payment by
the LOC Bank of such draw and (2) the Maximum Drawing Amount of such Letter of
Credit immediately prior to adjustment of the Maximum Drawing Amount of such
Letter of Credit for payment by the LOC Bank of such draw. If payment of the
amount due pursuant to the preceding sentence from a Participating Bank is
received by the LOC Bank after the Business Day on which it is due, such
Participating Bank agrees to pay to the LOC Bank, along with its payment of the
amount due pursuant to the preceding sentence, interest on such amount at a rate
per annum equal to (i) for the period from and including the Business Day such
payment is due to but excluding the next succeeding Business Day, the Fed Funds
Rate and (ii) for the period from and including the Business Day next succeeding
the Business Day such payment is due to but excluding the Business Day on which
such amount is paid in full, the Default Rate. The LOC Bank agrees to give
prompt telephonic notice (confirmed in writing) to a Participating Bank if the

Bank does not receive the payment required by this subsection (a) from such
Participating Bank on the Business Day on which such payment was due from such
Participating Bank.

      (b)  Upon receipt of a payment from the Company pursuant to Section 2
hereof, the LOC Bank shall promptly transfer to each Participating Bank such
Participating Bank's pro rata share (determined in accordance with such
Participating Bank's Participation Percentage) of such payment based on such
Participating Bank's pro rata share (determined as aforesaid) of amounts paid
pursuant to subsection (a) above, and not previously transferred by the LOC Bank
pursuant to this subsection (b); provided, however, that, if a Participating
Bank shall fail to pay to the LOC Bank any amount required by subsection (a),
above, on the Business Day following the date on which such payment was due from
such Participating Bank and the Company shall not have reimbursed the LOC Bank
for such amount pursuant to Section 2 hereof (such unreimbursed amount being
hereinafter referred to as a "TRANSFERRED AMOUNT"), the LOC Bank shall be deemed
to have purchased, on such following Business Day (a "PARTICIPATION TRANSFER
DATE") from such Participating Bank (a "DEFAULTING PARTICIPATING BANK"), a
participation in such Transferred Amount and shall be entitled, for the period
from and including the Participation Transfer Date to the earlier of (i) the
date on which the Company shall have reimbursed the LOC Bank for such
Transferred Amount and (ii) the date on which such Participating Bank shall have
reimbursed the LOC Bank for such Transferred Amount (the "PARTICIPATION TRANSFER
PERIOD"), to the rights, privileges and obligations (including, without
limitation, the obligation to make Advances pursuant to Section 2(c) hereof) of
a "Participating Bank" under this Agreement with a Participation Percentage
equal to the Participation Percentage of such Defaulting Participating Bank; and
provided further, however, that, if at any time after the occurrence of a
Participation Transfer Date with respect to any Participating Bank and prior to
the reimbursement by such Participating Bank of the LOC Bank with respect to the
related Transferred Amount pursuant to subsection (a), above, (i) the LOC Bank
shall receive any payment from the Company pursuant to Section 2 hereof, the LOC
Bank shall not be obligated to pay any amounts to such Participating Bank, and
the LOC Bank shall retain such amounts (including, without limitation, interest
payments due from the Company pursuant to Section 2 hereof) for its own account
as a Participating Bank or (ii) an Administrating Bank shall receive any payment
from the Company for the account of such Defaulting Participating Bank pursuant
to Section 3 or 21(b) hereof, such Administrating Bank shall not pay any such
amounts to such Defaulting Participating Bank but shall pay any such amounts to
the LOC Bank and the LOC Bank shall retain such amounts for its own account as a
Participating Bank; provided that all such amounts shall be applied in
satisfaction of the unpaid amounts (including, without limitation, interest

payments due from such Participating Bank pursuant to subsection (a), above) due
from such Participating Bank with respect to such Transferred Amount.

      (c)  All payments due to the Participating Banks from the LOC Bank
pursuant to subsection (b), above, shall be made to the Participating Banks if,
as, and to the extent possible, when the LOC Bank receives payments in respect
of drawings under the Letters of Credit or Advances pursuant to Section 2
hereof, and in the same funds in which such amounts are received; provided that,
if any Participating Bank to which the LOC Bank is required to transfer any such
payment (or any portion thereof) pursuant to subsection (b), above, does not
receive such payment (or portion thereof) on the same Business Day on which the
LOC Bank received such payment from the Company (which payment, if received by
the LOC Bank after 1:00 p.m., New York City time, on any Business Day shall be
deemed, for the purposes of this proviso, to have been received on the next
succeeding Business Day), the LOC Bank agrees to pay to such Participating Bank,
along with its payment of the portion of such payment due to such Participating
Bank, interest on such amount at a rate per annum equal to (i) for the period
from and including such Business Day of receipt by the LOC Bank to but excluding
the next succeeding Business Day, the Fed Funds Rate and (ii) for the period
from and including the Business Day next succeeding such Business Day of receipt
by the LOC Bank to but excluding the Business Day such amount is paid in full,
the Default Rate. The provisions of this subsection (c) and subsection (b),
above, shall not affect or impair any of the obligations under this Agreement of
any Defaulting Participating Bank to the LOC Bank.

      (d)  If, in connection with any case or other proceeding seeking
liquidation, reorganization or other relief with respect to the Company or its
debts under any bankruptcy, insolvency or other similar law now or hereafter in
effect, or for any other reason whatsoever, the LOC Bank shall be required to
return to the Company or to a trustee, receiver, liquidator, custodian or other
similar official all or any portion of payments or interest paid to a
Participating Bank pursuant to subsections (b) and (c), above (a "RETURNED
PAYMENT"), each Participating Bank shall, upon demand of the LOC Bank, forthwith
return to the LOC Bank any amounts transferred to such Participating Bank by the
LOC Bank in respect thereof pursuant to subsections (b) and (c), above, plus
such Participating Bank's pro rata share (determined in accordance with such
Participating Bank's Participation Percentage) of any interest that the LOC Bank
is required to pay to such trustee, receiver, liquidator, custodian or other
similar officer with respect to any Returned Payment.

      (e)  The LOC Bank will exercise and give the same care and attention to
the Letters of Credit as it gives to its other letters of credit and
<PAGE>
 
                                                                              35

similar obligations, and each Participating Bank agrees that the LOC Bank's
liability to each Participating Bank shall be (i) to distribute promptly, as and
when received by the LOC Bank and in accordance with the provisions of
subsections (b) and (c), above, such Participating Bank's pro rata share
(determined in accordance with such Participating Bank's Participation
Percentage) of any payments to the LOC Bank by the Company pursuant to Section 2
hereof in respect of drawings under the Letters of Credit or Advances, (ii) to
exercise or refrain from exercising any right or to take or to refrain from
taking any action under this Agreement or any Letter of Credit as may be
directed in writing by the Required Banks or the Administrating Banks or either
of them acting on behalf of the Required Banks, except to the extent required by
the terms hereof or thereof or by applicable law and (iii) as otherwise
expressly set forth herein. The LOC Bank shall not be liable for any action
taken or omitted at the request or with the approval of the Required Banks or
the Administrating Banks or either of them acting on behalf of the Required
Banks or for the nonperformance of the obligations of any other party under this
Agreement, any Letter of Credit, any of the Transaction Documents, any of the
Financing Documents, any of the Refinancing Documents or any other document
contemplated hereby or thereby. Without in any way limiting any of the
foregoing, the LOC Bank may rely upon the advice of the Administrating Banks
with respect to any of the LOC Bank's obligations under this Agreement or any
Letter of Credit, upon the advice of counsel and of independent public
accountants and other experts selected by it and upon any written communication
or telephone conversation that it believes to be genuine or to have been signed,
sent or made by the proper person and shall not be required to make any inquiry
concerning the performance by the Company, the Owner Trustee, any Owner
Participant, any General Partner, any Designated General Partner, any Limited
Partner or any other Person of any of its obligations and liabilities under or
in respect of this Agreement, the Letters of Credit, the Transaction Documents,
the Financing Documents, the Refinancing Documents or any other documents
contemplated hereby or thereby. The LOC Bank shall not have any obligation to
make any claim, or assert any Lien, upon any property held by the LOC Bank or
assert any offset thereagainst in satisfaction of all or part of the obligations
of the Company hereunder; provided that the LOC Bank shall, if so directed by
the Required Banks or the Administrating Banks or either of them acting on
behalf of and with the consent of the Required Banks, have an obligation to make
a claim, or assert a Lien, upon property held by the LOC Bank in connection with
this Agreement or assert an offset thereagainst. The LOC Bank may accept
deposits from, make loans or otherwise extend credit to, and generally engage in
any kind of banking or trust business with the Company or any of its Affiliates,
or any other Person, and receive payment on such loans or extensions of credit
and otherwise act with respect thereto freely and without accountability in the
same manner as

                                                                              36

if this Agreement and the transactions contemplated hereby were not in effect.
Without limiting any of the foregoing, the LOC Bank agrees that (x) it will not
give notice of a Date of Early Termination under a Letter of Credit without a
writing executed by the Required Banks or executed by the Administrating Banks
or either of them on behalf of and with the consent of the Required Banks
directing it to give such notice (which writing shall specify the Date of Early
Termination to be given in such notice) and (y) if a Reimbursement Event of
Default has occurred and is continuing, upon receipt of such a writing, it will
give such notice as provided in such Letter of Credit.

      (f)  The LOC Bank makes no representation or warranty and shall have no
responsibility with respect to: (i) the genuineness, legality, validity, binding
effect or enforceability of this Agreement, any of the Transaction Documents,
any of the Financing Documents, any of the Refinancing Documents or any other
documents contemplated hereby or thereby; (ii) the truthfulness, accuracy or
performance of any of the representations, warranties or agreements contained in
this Agreement, any of the Transaction Documents, any of the Financing
Documents, any of the Refinancing Documents or any other documents contemplated
hereby or thereby; (iii) the collectibility of any amounts due under this
Agreement; (iv) the financial condition of the Company or of any other Person;
or (v) any act or omission of any Owner Participant, any General Partner, any
Designated General Partner or any Limited Partner with respect to its use of any
Letter of Credit or the proceeds of any drawing under any Letter of Credit.
Each Participating Bank acknowledges and agrees that such Participating Bank has
been, and will continue to be, solely responsible for making its own independent
appraisal of and investigation into the financial condition, affairs, status and
nature of the Company and for making its own credit decision in taking or not
taking any action, including, without limitation, entering into this Agreement.

      (g)  To the extent that the LOC Bank is not reimbursed and indemnified by
the Company under Section 20, Section 21 or Section 22 hereof, each
Participating Bank agrees to reimburse and indemnify the LOC Bank on demand, pro
rata in accordance with such Participating Bank's Participation Percentage, from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever that may be imposed on, incurred by or asserted against the
LOC Bank, in any way relating to or arising out of any Letter of Credit, this
Agreement, any Financing Document, any Refinancing Document, any Transaction
Document or any other document contemplated hereby or thereby, or any action
taken or omitted by the LOC Bank under or in connection with this Agreement, any
Letter of Credit, any Financing Document, any Refinancing Document, any

Document or any other document contemplated hereby or thereby; provided,
however, that such Participating Bank shall not be liable for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the LOC Bank's gross
negligence or willful misconduct or from the LOC Bank's failure to refrain from
exercising or to exercise any right or to refrain from taking or to take any
action under this Agreement or the Letters of Credit, as directed in writing by
the Required Banks or by the Administrating Banks or either of them acting on
behalf of and with the consent of the Required Banks (unless such refrain from
exercising such right or action, such exercise or such taking was required by
the terms hereof or thereof or by applicable law); and provided further,
however, that such Participating Bank shall not be liable to the LOC Bank or any
other Participating Bank for the failure of the Company to reimburse the LOC
Bank or any other Participating Bank for any drawing made under a Letter of
Credit or any Advance with respect to which such Participating Bank has paid the
LOC Bank such Participating Bank's pro rata share (determined in accordance with
such Participating Bank's Participation Percentage), or for the Company's
failure to pay interest thereon.  Each Participating Bank's obligations under
this subsection (g) shall survive the payment in full of all amounts payable by
such Participating Bank under subsection (a), above, and the termination of this
Agreement and the Letters of Credit.  Nothing in this subsection (g) is intended
to limit any Participating Bank's reimbursement obligation contained in
subsection (a), above.

      (h)  Each Participating Bank agrees that it will promptly (i) notify Swiss
Bank Corporation of any occurrence giving rise to a right to compensation to
such Participating Bank pursuant to Section 4 hereof and (ii) submit to Swiss
Bank Corporation a certificate detailing such occurrence giving rise thereto and
the calculation of the amount of compensation with respect thereto.  Swiss Bank
Corporation agrees to present promptly such certificate to the Company in
accordance with Section 4 hereof.

      (i)  Each Participating Bank acknowledges and agrees that, except as
otherwise specifically provided herein, (i) its obligation to acquire a
participation in the LOC Bank's liability in respect of the Letters of Credit
and (ii) its obligation to make the payments specified herein, and the right of
the LOC Bank to receive the same, in the manner specified herein, are absolute,
unconditional and irrevocable and shall not be affected by any circumstances
whatsoever, including, without limitation, (A) the occurrence and continuance of
any Event of Default under any of the Facility Leases or any Reimbursement
Default or Reimbursement Event of Default hereunder or any breach or default by
the Company, either Administrating Bank or any Participating Bank hereunder; (B)
any lack of validity or enforceability of this

Agreement, any Letter of Credit, any of the Transaction Documents, any of the
Financing Documents or any of the Refinancing Documents; (C) the existence of
any claim, setoff, defense or other right which the Company may have at any time
against any Owner Participant, any General Partner, any Designated General
Partner, any Limited Partner or the Owner Trustee (or any Person for whom any of
the foregoing may be acting, including, without limitation, any General Partner
or Limited Partner of any Owner Participant), the LOC Bank, either
Administrating Bank, any Participating Bank or any other person or entity,
whether in connection with this Agreement, the Transaction Documents, the
Financing Documents, the Refinancing Documents or any other documents
contemplated hereby or thereby or any unrelated transactions; provided that
nothing herein shall prevent the assertion of any such claim by separate suit or
compulsory counterclaim; (D) any amendment or waiver of or consent to any
departure from all or any of the Letters of Credit, this Agreement, any of the
Transaction Documents, any of the Financing Documents or any of the Refinancing
Documents; (E) any statement or any document presented under any Letter of
Credit proving to be forged, fraudulent, invalid or insufficient in any respect
or any statement therein being untrue or inaccurate in any respect; (F) payment
by the LOC Bank under any Letter of Credit against presentation of a draft or
certificate that does not comply with the terms of such Letter of Credit, so
long as such payment is not the consequence of the LOC Bank's gross negligence
or willful misconduct in determining whether documents presented under a Letter
of Credit comply with the terms thereof; or (G) any other circumstance or
happening whatsoever, whether or not similar to any of the foregoing.

      (j)  In furtherance and not in limitation of any other provision hereof,
in the event that (i) a Participating Bank shall become a Defaulting
Participating Bank, (ii) a decree or order of a court, agency or supervisory
authority having jurisdiction in the premises for the appointment of a
conservator or receiver or liquidator in any insolvency proceeding, readjustment
of debt, marshalling of assets and liabilities or similar proceeding of a
Participating Bank or of all or substantially all of its property, or for the
winding up or liquidation of its affairs, shall have been entered, or a
Participating Bank shall consent to the appointment of a conservator or receiver
or liquidator in any insolvency, readjustment of debt, marshalling of assets and
liabilities or similar proceeding of such Participating Bank or of all or
substantially all of its property, or a Participating Bank shall file a petition
to take advantage of any applicable insolvency or reorganization statute or
voluntarily generally suspend payment of its obligations or (iii) the rating by
either Moody's or S&P of the long-term unsecured debt obligations or
certificates of deposit of (A) any Participating Bank (other than Union Bank and
The First National Bank of Boston) shall fall below A- or the then current
equivalent thereof or (B) The First National Bank of Boston shall fall

below BBB or the then current equivalent thereof (any Participating Bank as
described in clause (i), (ii) or (iii), above, being referred to herein as a
"NONPERFORMING PARTICIPATING BANK"), then the LOC Bank may find one or more
financial institutions to assume the obligations hereunder of such Nonperforming
Participating Bank (each a "SUBSTITUTING PARTICIPATING BANK") pursuant to one or
more Assignment Agreements, and, when such Assignment Agreement(s) have been
accepted by Union Bank, each Substituting Participating Bank shall succeed to
all or a portion, as applicable, of the rights, privileges and obligations of
such Nonperforming Participating Bank hereunder and such Substituting
Participating Bank shall become a "Participating Bank" for purposes of this
Agreement; provided, however, that if at the time a Substituting Participating
Bank succeeds to the rights, privileges and obligations of a Nonperforming
Participating Bank such Nonperforming Participating Bank has an interest in
outstanding drawings or Advances, the Substituting Participating Bank shall have
purchased such interest, or a portion of such interest equal to the portion of
the Nonperforming Participating Bank's interest hereunder purchased by such
Substituting Participating Bank, of the Nonperforming Participating Bank at
market value; and provided further, however, that such succession of each such
Substituting Participating Bank shall be subject to the prior written consent of
the Company (which shall not be unreasonably withheld or delayed).

      SECTION 6. PAYMENTS.

      (a)  All payments by the Company or the Participating Banks to the LOC

      (b)  Whenever any payment under this Agreement shall be due on a day that
is not a Business Day, the date for payment thereof shall be extended to the

all payments hereunder from the Company to the Participating Banks, from the LOC
Bank or Union Bank to the Participating Banks, from the Participating Banks to
the LOC Bank and from the Participating Banks to an Administrating Bank shall be
made pro rata among the Participating Banks in accordance with the Participation
Percentages of such Participating Banks.

have made any demand under this Agreement and although such obligations may be
unmatured.  The LOC Bank and each other Bank agree to notify the Company
promptly after any such setoff and application made thereby, but the failure to
give such notice shall not affect the validity of such setoff and application.
The rights of the LOC Bank and each other Bank under this Section are in
addition to other rights and remedies (including, without limitation, other
rights of setoff) that the LOC Bank or such other Bank may have.

      (b)  Each Participating Bank agrees that if it shall, through the exercise
of a right of banker's lien, setoff or counterclaim against the Company,
including, but not limited to, a secured claim under Section 506 of Title 11 of
the United States Code or other security or interest arising from, or in lieu
of, such secured claim, received by such Participating Bank under any applicable
bankruptcy, insolvency or other similar law or otherwise, obtain payment
(voluntary or involuntary) in respect of amounts paid by it pursuant to Section
5(a) as a result of which the unreimbursed portion of Section 5(a) payments made
by it shall be proportionately less (determined in accordance with each
Participating Bank's Participation Percentage) than the unreimbursed portion of
Section 5(a) payments made by any other Participating Bank, it shall be deemed
to have simultaneously purchased from such other Participating Bank a
participation in the unreimbursed portion of Section 5(a) payments made by such
other Participating Bank, so that the

                                                                              63

aggregate unreimbursed portion of Section 5(a) payments made by it and
participations in the unreimbursed portion of Section 5(a) payments made by each
other Participating Bank and held by it shall be in the same proportion
(determined in accordance with each Participating Bank's Participation
Percentage) to the aggregate unreimbursed portion of Section 5(a) payments made
by all Participating Banks as the principal amount of the unreimbursed portion
of Section 5(a) payments made by it prior to such exercise of banker's lien,
setoff or counterclaim was to the unreimbursed portion of all Section 5(a)
payments made by all Participating Banks prior to such exercise of banker's
lien, setoff or counterclaim; provided, however, that, if any such purchase
shall be made pursuant to this Section 17(b) and the payment giving rise thereto
shall thereafter be recovered, such purchase shall be rescinded to the extent of
such recovery and the purchase price restored. The Company expressly consents to
the foregoing arrangements and agrees that any Participating Bank holding a
participation in an unreimbursed portion of a Section 5(a) payment deemed to
have been so purchased may exercise any and all rights of banker's lien, setoff
or counterclaim with respect to any and all moneys owing by the Company to such
Participating Bank as fully as if such Participating Bank held an unreimbursed
portion of a Section 5(a) payment in the amount of such participation.

      SECTION 18. CONTINUING OBLIGATION.  The obligations of the Company under
this Agreement shall continue until the later of (i) the Termination Date of the
last outstanding Letter of Credit and (ii) the date upon which all amounts due
and owing to the LOC Bank, the Administrating Banks and the other Banks
hereunder (including, without limitation, all Advances, interest thereon, fees
and expenses) shall have been paid in full and shall (A) be binding upon the
Company and its successors and assigns and (B) inure to the benefit of and be
enforceable by the LOC Bank, each Administrating Bank and each other Bank, and
their successors, transferees and assigns; provided, however, that the Company
may not assign all or any part of this Agreement without the prior written
consent of the LOC Bank and the other Banks.

      SECTION 19. EXTENSION OF LETTERS OF CREDIT.  At least 6 months but not
more than 12 months before October 2, 1999, the Company may request the LOC Bank
and the Participating Banks, by giving written notice of such request to the
Administrating Banks, to extend the Stated Expiration Date of any Letter of
Credit, specifying the terms and conditions, including fees, to be applicable to
such extension.  The Administrating Banks shall promptly notify the LOC Bank and
each Participating Bank of such request, and, no later than 90 days from the
date on which the Administrating Banks shall have received notice from the
Company pursuant to the preceding sentence, the Administrating Banks shall
notify the Company of the consent or nonconsent to such extension request.  No
extension shall be effective without

                                                                              64

the consent of the LOC Bank and all of the Participating Banks. The consent of
the LOC Bank and all of the Participating Banks shall be conditional upon the
preparation, execution and delivery of legal documentation in form and substance
satisfactory to the LOC Bank and all of the Participating Banks and their
counsel incorporating substantially the terms and conditions contained in the
extension request as the same may be modified by agreement among the Company and
the Banks.

      SECTION 20. LIMITED LIABILITY OF THE BANKS.  As between the Company, on
the one hand, and the LOC Bank, the other Banks and the Administrating Banks, on
the other hand, the Company assumes all risks of the acts or omissions of the
Owner Participants, the General Partners, the Designated General Partners and
the Limited Partners with respect to their use of the Letters of Credit.  None
of the LOC Bank, the Administrating Banks, the other Banks or any of their
officers or directors shall be liable or responsible for: (a) the use that may
be made of the Letters of Credit or for any acts or omissions of the Owner
Participants, the General Partners, the Designated General Partners or the
Limited Partners in connection therewith; (b) the validity, sufficiency or
genuineness of documents, or of any endorsements thereon, even if such documents
should in fact prove to be in any or all respects invalid, insufficient,
fraudulent or forged; (c) payment by the LOC Bank against presentation of
documents that do not comply with the terms of the appropriate Letter of Credit,
including failure of any documents to bear any reference or adequate reference
to the appropriate Letter of Credit; or (d) any other circumstances whatsoever
in making or failing to make payment under any Letter of Credit, except only
that the Company and the Participating Banks shall have a claim against the LOC
Bank, and the LOC Bank shall be liable to the Company and the Participating
Banks to the extent, but only to the extent, of any direct, as opposed to
consequential, damages suffered by the Company or the Participating Banks, as
the case may be, that the Company or the Participating Banks, as the case may
be, prove were caused by (i) the LOC Bank's willful misconduct or gross
negligence in determining whether documents presented under a Letter of Credit
comply with the terms thereof or (ii) the LOC Bank's willful failure to pay
under a Letter of Credit after the presentation to it by the appropriate Owner
Participant, Designated General Partner or Limited Partner, as the case may be,
of a draft and certificate strictly complying with the terms and conditions of
such Letter of Credit. In furtherance and not in limitation of the foregoing,
the LOC Bank may accept documents that appear on their face to be in order,
without responsibility for further investigation, regardless of any notice or
information to the contrary. Nothing in this Section 20 is intended to limit the
Company's reimbursement and repayment obligations contained in Section 2 hereof
or any Participating Bank's reimbursement obligation contained in Section 5(a)
hereof. Without prejudice to the survival of any
<PAGE>
 
                                                                              65

other obligation of the Company hereunder, the obligations of the Company
contained in this Section 20 shall survive the payment in full of amounts
payable by the Company under Section 2 hereof and by the Participating Banks
under Section 5(a) hereof, termination of the Letters of Credit, reimbursement
to the LOC Bank of any payments or disbursements under the Letters of Credit and
termination of this Agreement.

      SECTION 21. COSTS, EXPENSES AND TAXES.  The Company agrees to pay not
later than 30 days after demand therefor, (i) whether or not the transactions
contemplated herein are consummated, all reasonable costs and expenses of the
Administrating Banks and the LOC Bank in connection with the preparation,
review, execution, delivery, filing, recording and administration of this
Agreement, the Letters of Credit, the Transaction Documents, the Financing
Documents, the Refinancing Documents and any other documents that may be
delivered in connection herewith or therewith, including, without limitation,
the reasonable fees and out-of-pocket expenses of respective counsel for the
Administrating Banks and the LOC Bank with respect thereto and with respect to
advising and representing the Administrating Banks and the LOC Bank with respect
to their rights and responsibilities under, or any waiver, amendment or
enforcement of (including, without limitation, in the case of any default or
prospective default), this Agreement, the Letters of Credit, the Transaction
Documents, the Financing Documents, the Refinancing Documents or any other
documents that may be delivered in connection herewith or therewith, or any
action or proceeding relating to a court order, injunction or other process or
decree restraining or seeking to restrain the LOC Bank from paying any amount
under any Letter of Credit and (ii) all reasonable fees and out-of-pocket
expenses of respective counsel for each Participating Bank in connection with
the enforcement (whether through negotiations, legal proceedings or otherwise)
of this Agreement in the event of the occurrence of any event set forth in
Section 13(g) hereof. In addition, the Company shall pay any and all stamp and
other taxes and fees payable or determined to be payable in connection with the
execution, delivery, filing and recording of this Agreement, the Letters of
Credit, the Transaction Documents, the Financing Documents, the Refinancing
Documents and such other documents and agrees to hold the Administrating Banks
and the LOC Bank harmless from and against any and all liabilities with respect
to or resulting from any delay in paying or omission to pay such taxes and fees;
provided that the Administrating Banks and the LOC Bank agree to notify the
Company promptly of any such taxes and fees that are incurred thereby. Without
prejudice to the survival of any other obligation of the Company hereunder, the
obligations of the Company contained in this Section 21 shall survive the
payment in full of amounts payable by the Company under Section 2 hereof and by
the Participating Banks under Section 5(a) hereof, termination of the 
<PAGE>
 
                                                                              66

Letters of Credit, reimbursement to the LOC Bank of any payments or
disbursements under the Letters of Credit and termination of this Agreement.

      SECTION 22. INDEMNIFICATION.  The Company hereby agrees to indemnify and
hold harmless the LOC Bank, each Administrating Bank and each other Bank from
and against any and all claims, damages, losses, liabilities, costs or expenses
whatsoever that the LOC Bank or such Administrating Bank or other Bank may incur
(or that may be claimed against the LOC Bank or such Administrating Bank or
other Bank by any Person whatsoever) (a) by reason of any inaccuracy in any
material respect, or untrue statement or alleged untrue statement of any
material fact contained or incorporated by reference in any offering document
distributed by or on behalf of the Company in connection with obtaining
purchasers of the Company's undivided interest in Unit 2, or in any supplement
or amendment to either thereof, or the omission or alleged omission to state
therein a material fact necessary to make such statements, in the light of the
circumstances under which they are or were made, not misleading; (b) by reason
of or in connection with the execution, delivery and performance of this
Agreement, the Transaction Documents, the Financing Documents or the Refinancing
Documents, or any transaction contemplated hereby or thereby; or (c) by reason
of or in connection with the execution and delivery or transfer of, or payment
or failure to make lawful payment under, any Letter of Credit; provided that the
Company shall not be required to indemnify the LOC Bank or any Administrating
Bank or other Bank for any claims, damages, losses, liabilities, costs or
expenses to the extent, but only to the extent, caused by the willful misconduct
or gross negligence of the LOC Bank in determining whether a draft or
certificate presented under a Letter of Credit complied with the terms of such
Letter of Credit or the LOC Bank's willful failure to make lawful payment under
a Letter of Credit after the presentation to it by the appropriate Owner
Participant, Designated General Partner or Limited Partner, as the case may be,
of a draft and certificate strictly complying with the terms and conditions of
such Letter of Credit. Notwithstanding the generality of the foregoing, the
failure by the LOC Bank to make payment under an LP Letter of Credit after
presentation to it by the appropriate Owner Participant, Designated General
Partner or Limited Partner, as the case may be, of a draft and a certificate
strictly in conformance with the terms and conditions of such LP Letter of
Credit, shall not constitute the gross negligence or willful misconduct of the
LOC Bank if such failure to make payment under any such draft is the result of
the strict compliance by the LOC Bank with the provisions set forth in the
eighth paragraph of such LP Letter of Credit. Nothing in this Section 22 is
intended to limit the Company's reimbursement and repayment obligations
contained in Section 2 hereof or any Participating Bank's reimbursement
obligation contained in Section 5(a) hereof. Without prejudice to the survival
of any

                                                                              67

other obligation of the Company hereunder, the indemnities and obligations of
the Company contained in this Section 22 shall survive the payment in full of
amounts payable by the Company under Section 2 hereof and by the Participating
Banks under Section 5(a) hereof, termination of the Letters of Credit,
reimbursement to the LOC Bank of any payments or disbursements under the Letters
of Credit, termination of this Agreement and, with respect to any Participating
Bank, such Participating Bank's becoming a Nonperforming Participating Bank.

      SECTION 23. SALES OF PARTICIPATIONS AND ASSIGNMENTS.

      (a)  Without the consent of the LOC Bank, the Administrating Banks, the
Company or any other Participating Bank, each Participating Bank may grant
participations in its participation in the Letters of Credit (each Person to
which a participation is granted being called a "PARTICIPANT"); provided,
however, that (i) such Participating Bank's obligations under this Agreement
shall remain unchanged; (ii) such Participating Bank shall remain solely
responsible to the other parties hereto for the performance of such obligations;
(iii) the Company, the Administrating Banks, the LOC Bank and the other Banks
shall continue to deal solely and directly with such Participating Bank in
connection with such Participating Bank's rights and obligations under this
Agreement; and (iv) any Participant of such Participating Bank shall not be
entitled to require such Participating Bank to take or omit to take any action
hereunder, except any action (A) extending the Termination Dates of the Letters
of Credit or the dates for reimbursement of drawings under the Letters of Credit
or for repayment of Advances, or for the payment of interest thereon, or (B)
reducing the rate of interest on any unreimbursed drawings or Advances or the
fees provided for in Section 3(a) hereof. If, at the time of a grant of a
participation pursuant to this subsection (a), the proposed Participant is
subject to Taxes that would result in a claim for compensation pursuant to
Section 4(d) hereof materially greater than that to which the Participating Bank
granting such participation is entitled, such grant shall be subject to the
consent of the Company (which consent shall not be unreasonably withheld).

      (b)  With the prior written consent of the LOC Bank and the Company (which
consent in the case of the Company shall not be unreasonably withheld or delayed
and, in the case of an assignment to another Participating Bank or to an
Affiliate of a Participating Bank, shall not be required), any Participating
Bank may assign all or a portion (but in no event less than $5,000,000) of its
obligations hereunder to one or more financial institutions, and,
notwithstanding the provisions of Section 14 hereof, upon the execution of an
Assignment Agreement by such Participating Bank and such financial institution,
the delivery of such Assignment Agreement to
<PAGE>
 
                                                                              68

Union Bank (together with a processing fee of $2,000) and the acceptance of such
Assignment Agreement by Union Bank, such financial institution shall become a
"Participating Bank" for purposes of this Agreement and shall be entitled to the
rights, privileges and obligations of a Participating Bank hereunder, and such
assigning Participating Bank shall be released from its obligations with respect
to the portion of its participation so assigned.

      (c)  The Company shall be permitted to replace any Participating Bank that
requests reimbursement for amounts owing pursuant to Section 4(a) with a
replacement bank or other financial institution; provided that (i) such
replacement does not conflict with any applicable law, (ii) no Reimbursement
Default shall have occurred and be continuing at the time of such replacement,
(iii) prior to the date of replacement, the replacement bank or institution
shall purchase, at par, all amounts owing to such replaced Participating Bank,
(iv) the replacement bank or institution, if not already a Participating Bank,
and the terms and conditions of such replacement, shall be acceptable to the
Administrating Banks and the LOC Bank in their sole and absolute discretion, (v)
the replaced Participating Bank shall be obligated to make such replacement in
accordance with the provisions of subsection (b), above, (vi) until such time as
such replacement shall be consummated, the Company shall pay all additional
amounts (if any) required pursuant to Section 4(a), and (vii) any such
replacement shall not be deemed to be a waiver of any rights which the Company,
the Administrating Banks, the LOC Bank or any other Participating Bank may have
against the replaced Participating Bank.

      SECTION 24. ADMINISTRATING BANKS.

      (a)  In order to expedite the various transactions contemplated by this
Agreement, Union Bank and Swiss Bank Corporation are hereby appointed to act as
Administrating Banks on behalf of the LOC Bank and the Participating Banks.  The
LOC Bank and each Participating Bank hereby authorize and direct the
Administrating Banks and each of them to take such action on behalf of the LOC
Bank and such Participating Bank under the terms and provisions of this
Agreement and to exercise such powers hereunder as are specifically delegated to
or required of the Administrating Banks or either of them by the terms and
provisions hereof, together with such powers as are reasonably incidental
thereto.  The Administrating Banks and each of them are hereby expressly
authorized on behalf of the LOC Bank and the Participating Banks, in accordance
with the terms hereof and without hereby limiting any other express or implied
authority, (i) to receive on behalf of the LOC Bank and each of the
Participating Banks any payment of fees due to the LOC Bank or the Participating
Banks hereunder and all other amounts accrued hereunder paid to the
Administrating Banks or either of
<PAGE>
 
                                                                              69

them for the accounts of the LOC Bank and the Participating Banks, and promptly
to distribute to the LOC Bank and to each Participating Bank its proper share of
all payments so received; (ii) to give notice within a reasonable time on behalf
of each of the Participating Banks to the Company of any Reimbursement Event of
Default specified in this Agreement of which the Administrating Banks or either
of them has actual knowledge acquired in connection with its capacity as an
Administrating Bank hereunder; and (iii) to distribute to the LOC Bank and each
Participating Bank copies of all notices, agreements and other material as
provided for in this Agreement as received by the Administrating Banks or either
of them.

      (b)  Neither Administrating Bank nor any of its directors, officers,
employees or agents shall be liable as such for any action taken or omitted by
any of them hereunder except for its or his own gross negligence or willful
misconduct, or be responsible for any statement, warranty or representation
herein or the contents of any document delivered in connection herewith or be
required to ascertain or to make any inquiry concerning the performance or
observance by the Company of any of the terms, conditions, covenants or
agreements of this Agreement.  The Administrating Banks shall not be responsible
to the Banks for the due execution, genuineness, validity, enforceability or
effectiveness of this Agreement, the Letters of Credit or any other instrument
to which reference is made herein.  The Administrating Banks shall in all cases
be fully protected in acting, or refraining from acting, in accordance with
written instructions signed by the Required Banks, and, except as otherwise
specifically provided herein, such instructions and any action taken or failure
to act pursuant thereto shall be binding on all the Participating Banks.  The
Administrating Banks shall, in the absence of knowledge to the contrary, be
entitled to rely on any paper or document believed thereby to be genuine and
correct and to have been signed or sent by the proper Person or Persons.
Neither Administrating Bank nor any of such bank's directors, officers,
employees or agents shall have any responsibility to the Company or the LOC Bank
on account of the failure or delay in performance or breach by any Bank of any
of its obligations hereunder or to any Participating Bank on account of the
failure of or delay in performance or breach by any other Participating Bank,
the LOC Bank or the Company of any of their respective obligations hereunder or
in connection herewith.  The Administrating Banks may execute any and all duties
hereunder by or through agents or employees and shall be entitled to advice of
legal counsel selected by them with respect to all matters arising hereunder and
shall not be liable for any action taken or suffered in good faith in accordance
with the advice of such counsel.

      (c)  With respect to its Participation Percentage hereunder, each
Administrating Bank, in its individual capacity and not as an Administrating
<PAGE>
 
                                                                              70

Bank, shall have the same rights and powers hereunder and under any other
agreement executed in connection herewith as any other Participating Bank and
may exercise the same as though it were not an Administrating Bank, and each
Administrating Bank and its Affiliates may accept deposits from, lend money to
and generally engage in any kind of business with, the Company, any Subsidiary
or any other Affiliate thereof as if it were not an Administrating Bank.

      (d)  Each Participating Bank agrees (i) to reimburse each Administrating
Bank in the amount of such Participating Bank's pro rata share (determined in
accordance with such Participating Bank's Participation Percentage) of any
expenses incurred for the benefit of the Participating Banks by such
Administrating Bank, including fees and expenses of counsel and compensation of
agents and employees paid for services rendered on behalf of the Participating
Banks, not reimbursed by the Company and (ii) to indemnify and hold harmless
each Administrating Bank and any of its directors, officers, employees or
agents, on demand, in the amount of its pro rata share (determined as
aforesaid), from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever that may be imposed on, incurred by or asserted
against it in its capacity as an Administrating Bank in any way relating to or
arising out of this Agreement or any action taken or omitted by it or any of
them under this Agreement, to the extent not reimbursed by the Company, provided
that no Participating Bank shall be liable to an Administrating Bank for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the gross
negligence or willful misconduct of such Administrating Bank or any of its
directors, officers, employees or agents.

      (e)  Each Participating Bank acknowledges that it has, independently and
without reliance upon the LOC Bank, the Administrating Banks or any other
Participating Bank and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement.  Each Participating Bank also acknowledges that it will,
independently and without reliance upon the LOC Bank, the Administrating Banks
or any other Participating Bank and based on such documents and information as
it shall deem appropriate at the time, continue to make its own decisions in
taking or not taking action under or based upon this Agreement, any related
agreement or any document furnished hereunder.

      SECTION 25. SEVERABILITY.  Any provision of this Agreement that is
prohibited, unenforceable or not authorized in any jurisdiction shall, as to
<PAGE>
 
                                                                              71

such jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or nonauthorization without invalidating the remaining
provisions hereof or affecting the validity, enforceability or legality of such
provision in any other jurisdiction. The parties shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions, the economic effect of which comes as close as possible to
that of the invalid, illegal or unenforceable provisions.

      SECTION 26. GOVERNING LAW.  This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York.  The Company,
the Administrating Banks, the LOC Bank and the other Banks each (i) irrevocably
submits to the jurisdiction of any New York State court or Federal court sitting
in New York City in any action arising out of this Agreement or the Letters of
Credit, (ii) agrees that all claims in such action may be decided in such court,
(iii) waives, to the fullest extent it may effectively do so, the defense of an
inconvenient forum and (iv) consents to the service of process by mail.  A
final, non-appealable judgment in any such action shall be conclusive and may be
enforced in other jurisdictions.  Nothing herein shall affect the right of any
party to serve legal process in any manner permitted by law or affect its right
to bring any action in any other court.

      SECTION 27. RELATIONS OF PARTIES.  No term, provision or requirement of
this Agreement or any Letter of Credit, whether express or implied, shall (i) be
construed to create a partnership, association or other arrangement by or under
which the LOC Bank, the Administrating Banks or the other Banks shall be liable
for any obligation of the Company under any Transaction Document, Financing
Document or Refinancing Document, (ii) entitle any party thereto to a right of
reimbursement or contribution from the LOC Bank, the Administrating Banks or the
other Banks with respect thereto or (iii) secure, in any way, the claim of a
party thereunder.  In addition, the Company acknowledges and agrees that the
relationship created under this Agreement between the Company on the one hand,
and the LOC Bank and the other Banks, on the other hand, is a debtor/creditor
relationship, separate and distinct from the relationship between or among the
Company and the Owner Trustee, any Owner Participant, any General Partner, any
Designated General Partner, any Limited Partner and/or any other Person.

      SECTION 28. HEADINGS AND TABLE OF CONTENTS.  Section headings in, and the
Table of Contents of this Agreement are included herein for convenience of
reference only and shall not constitute a part of this Agreement for any other
purpose.

      SECTION 29.  COUNTERPARTS AND EFFECTIVENESS.  (a) This Agreement may be

Attention:  [                ]

Dear Sirs:

      1.   We hereby establish, at the request of Duquesne Light Company (the
"Company"), in your favor, our Irrevocable Transferable Letter of Credit No. 
[          ] (the "Letter of Credit"), in an amount not to exceed $[         ]
(as such amount may be reduced pursuant to the terms hereof, the "Maximum Credit

New York City time, on the Date of Early Termination (as hereinafter defined),
(ii) 3:00 p.m., New York City time, on the date on which the Owner Participant
surrenders the Letter of Credit to the Bank with a notice in the form of Exhibit

which the Bank pays an OP Final Draw (as hereinafter defined), and (iv) 3:00

certificate, all in strict conformity with the terms and conditions of the

      2.  The Maximum Credit Amount and the Maximum Drawing Amounts may be
reduced at any time and from time to time upon receipt by us at the address for
presentation of documents set forth below of a copy of the instrument effecting
such reductions, signed by the Company and by you in the form of Exhibit 1
hereto (a "Reduction Certificate").  Upon receipt of such certificate, the
Maximum Credit Amount shall be automatically and permanently reduced by the
amount specified as the Reduction Amount in such Reduction Certificate (the
"Reduction Amount") and, if requested in such Certificate, the Maximum Drawing
Amounts shall be automatically and permanently reduced as specified in such
Reduction Certificate.

      3.   We hereby irrevocably authorize you to draw on us, in accordance with
the terms and conditions hereinafter set forth, an amount not in excess of the
least of (x) the Maximum Drawing Amount applicable to the date of such drawing
(the "Date of Drawing"), as modified in accordance with the next paragraph, (y)
the Maximum Available Credit Amount, as modified in accordance with the next
paragraph and (z) in the case of an OP Partial Draw (as hereinafter defined),

      4.   The Maximum Drawing Amounts and the Maximum Available Credit Amount
shall be modified from time to time as follows:

          (a) upon receipt by us of a Reduction Certificate, (i) the Maximum
Available Credit Amount shall be permanently reduced by the Reduction Amount set
forth in such Reduction Certificate and (ii) if requested in such Certificate,
the Maximum Drawing Amounts shall be permanently reduced as specified in such
Reduction Certificate; provided, that, in no event shall any Maximum Drawing
Amount (after giving effect to any such reduction) exceed the Maximum Available
Credit Amount (after giving effect to such reduction);

          (b) upon payment by us of each OP Partial Draw under the Letter of
Credit, (i) the Maximum Drawing Amount applicable to each Date of Drawing
subsequent to such payment shall be automatically reduced by an amount equal to
the amount of the drawing so paid and (ii) the Maximum Available Credit Amount
shall be automatically reduced by an amount equal to the amount of the drawing
so paid;

          (c) upon the application by us of amounts paid by the Company pursuant
to Section 2(b)(ii) of the Reimbursement Agreement to reimburse any OP Partial
Draw hereunder (as such application is allocated in accordance with Section 2(d)
of the Reimbursement Agreement), (i) the Maximum Drawing Amount applicable to
each Date of Drawing subsequent to such application shall be automatically
increased by the amount of such

                                                                               3

payment(s) allocated as a reimbursement of drawings hereunder and (ii) the
Maximum Available Credit Amount shall be automatically increased by the amount
of such payment(s) allocated as a reimbursement of drawings hereunder; provided,
however, that the Maximum Available Credit Amount shall never exceed the Maximum
Credit Amount;

          (d) upon the payment by us of any OP Final Draw under the Letter of
Credit, (i) the Maximum Drawing Amount applicable to each Date of Drawing
subsequent to such payment shall be automatically reduced to zero and (ii) the
Maximum Available Credit Amount shall be automatically reduced to zero, and all
such amounts, in each case, shall not be reinstated; and

          (e) if adjustments are made to Modified Special Casualty Values,
corresponding adjustments shall be made to the Maximum Drawing Amounts shown in
Schedule II (as theretofore reduced pursuant to clause (a) or (b) above and, if
applicable, reinstated pursuant to clause (c) above); provided that adjustments
pursuant to this clause (e) shall be effective automatically upon receipt by us
of a notice from you in the form of Exhibit 2 hereto; and provided, further that
in no event shall any Maximum Drawing Amount, as adjusted, exceed the Maximum
Credit Amount.

      5.   Upon return of this Letter of Credit, together with a notice in the
form of Exhibit 2 hereto, we will promptly initial and attach to this Letter of
Credit a revised Schedule II reflecting the adjustments contained in such notice
and return this Letter of Credit to you with such revised Schedule attached.

Such notice shall be given in accordance with the provisions set forth in the
eighth paragraph of this Letter of Credit.

      7.   Funds under this Letter of Credit are available to you, either (a)

attached hereto (an "OP Final Draw").  Such draft and certificate shall be dated

you at least 15 days prior to the applicable Date of Drawing).  We agree that,
so long as this Letter of Credit is in effect, we will maintain an office in New

certificate which are not in strict conformity with the terms and conditions of
this Letter of Credit, we will promptly (and in any event within three Business
Days of such receipt) notify you of such nonconformity and the reason therefor;
provided that our failure to so notify you of such nonconformity or the reason
therefor shall not amend, modify, extend or otherwise affect your rights
hereunder and shall not create any additional rights hereunder; and provided
further that, notwithstanding the generality of the foregoing, any such failure
shall not have the effect of extending the time during which you may draw
hereunder or converting such nonconforming draft and certificate into a draft
and certificate in strict conformity with the terms and conditions of this
Letter of Credit.  Payment due to you under this Letter of Credit, as provided
above, shall be made by wire transfer of federal funds to your account specified
in the draft presented in connection with such OP Final Draw or OP Partial Draw.

      8.   Notwithstanding any other provision of this Letter of Credit, we
shall have the right, upon the occurrence of any of the events listed in
Schedule III hereto, to terminate this Letter of Credit by delivering to you a
written notice indicating the date of such termination (the "Date of Early
Termination"); provided that, on or before the Date of Early Termination, you
will have the right to draw once an amount not in excess of the lesser of (i)
the Maximum Available Credit Amount and (ii) the Maximum Drawing Amount, in
accordance with the procedures described herein; and provided, further, that,
upon delivery of such written notice to you indicating the Date of Early
Termination, your right to make an OP Partial Draw hereunder shall automatically
terminate.  The written notice referred to in the preceding sentence shall be
given by telex or facsimile transmission to you at the address specified in

<PAGE>

will also forward a copy of such notice by overnight delivery service to the

The Date of Early Termination specified in such written notice shall be:

III, not earlier than ten days after such notice is given, and

           (b) in the case of all other events specified in Schedule III, not
earlier than 30 days after such notice is given.

      9.   Except as set forth below, this Letter of Credit shall be governed by
the Uniform Customs and Practice for Documentary Credits, 1993 Revision
(revision effective January 1, 1994), International Chamber of Commerce
Publication No. 500, as amended, supplemented, revised or restated, and, as to

upon surrender of this Letter of Credit, issue an irrevocable transferable
letter of credit in the name of the transferee and providing for notices to be
sent to the transferee at the address set forth therein and in all other
respects identical to this Letter of Credit and the transferee, instead of the
transferor, shall, without necessity of further act, be entitled to all the
benefits of, and rights under, this Letter of Credit in the transferor's place.

      11.  Any drawing under this Letter of Credit will be paid from the general

                FORM OF OPINION OF CHIEF COUNSEL OF THE COMPANY


[Date of Issuance of the
Letters of Credit]



To each of the Participating Banks
 parties to the Reimbursement Agreement
 referred to below, to Swiss Bank Corporation,
 New York Branch, as LOC Bank, and to Union
 Bank and Swiss Bank Corporation, New York
 Branch, as Administrating Banks


                             Duquesne Light Company


Ladies and Gentlemen:

      I am Chief Counsel of Duquesne Light Company, a Pennsylvania corporation
(the "Company"), and I, or other attorneys under my supervision, have
represented it in connection with the transactions contemplated by the
Reimbursement Agreement, dated as of October 1, 1994 (the "Reimbursement

not otherwise defined herein shall have the meanings set forth in the

<PAGE>
 
                                                                               2

the Company's absolute and unconditional obligation to pay rent and other

the Owner Trustees to realize the residual value of their interests; Securities
Certificate No. S-920240 captioned "Securities Certificate of Duquesne Light
Company in respect of Substitute Letters of Credit and a new Reimbursement
Agreement in connection with the sale and leaseback of interests in Beaver
Valley Unit No. 2" (the "1992 Securities Certificate"), filed with the PPUC; the
Order of the PPUC adopted and entered on September 25, 1987 registering the
Securities Certificate (the "Securities Order"); the Order of the PPUC adopted
and entered on September 25, 1987 approving the Application (the "Application
Order"); the Order of the PPUC adopted and entered on July 9, 1992 (the "1992
PPUC Order"; the 1992 PPUC Order, the Securities Order and the Application Order
are referred to herein collectively as the "PPUC Orders"); and such other
agreements, records and documents, and such matters of law, as I have deemed
necessary or advisable for the purpose of rendering the opinions set forth
herein.

      In rendering the opinions hereinafter expressed, I have relied as to
factual matters on the representations in the Reimbursement Agreement, the
Collateral Trust Indenture and the Transaction Documents and I have further
assumed that:

      A.   Each party other than the Company (an "Other Party") to the
Reimbursement Agreement, the Collateral Trust Indenture, the Transaction
Documents and the Refinancing Documents is duly organized and validly existing
in good standing under the laws of the jurisdiction of its organization and has
the power and authority to enter into and perform its obligations under the
Reimbursement Agreement, the Collateral Trust Indenture and the Transaction
Documents and Refinancing Documents to which it is a party.

      B.   The execution, delivery and performance by each Other Party to the
Reimbursement Agreement, the Collateral Trust Indenture, the Transaction
Documents and the Refinancing Documents has been duly authorized by all
necessary action by such Other Party.  Each of the
<PAGE>
 
                                                                               3


Reimbursement Agreement, the Collateral Trust Indenture, the Transaction
Documents and the Refinancing Documents has been duly executed and delivered by
each Other Party thereto and to the extent the same is governed by the laws of
any state or other jurisdiction, other than the Commonwealth of Pennsylvania,
constitutes the legal, valid and binding obligation of each Other Party thereto,
enforceable against such Other Party in accordance with its terms.

      C.   Each Other Party has, during its negotiations with the Company of the
terms of the Reimbursement Agreement, the Collateral Trust Indenture and the
Transaction Documents and Refinancing Documents to which it is a party, acted in
good faith and in a commercially reasonable manner and not made any intentional
misrepresentations to the Company nor failed to disclose to the Company any
material facts.

      D.   Each Other Party will, in enforcing its remedies and in fulfilling
its responsibilities under the Reimbursement Agreement, the Collateral Trust
Indenture and the Transaction Documents and Refinancing Documents to which it is
a party, (i) act in good faith and in a commercially reasonable manner, (ii) not
make any misrepresentations to the Company, (iii) not fail to disclose to the
Company any material facts, (iv) not exercise control over the affairs of the
Company and (v) not interfere with the Company's contractual relations with
third Persons.

      E.   The express terms of the Reimbursement Agreement, the Collateral
Trust Indenture, the Transaction Documents and the Refinancing Documents have
not been, and will not be, amended, supplemented or deleted by a course of
conduct or dealing between any Other Party and the Company.

      F.   No Other Party to the Reimbursement Agreement, the Collateral Trust
Indenture, any Transaction Document or any Refinancing Document is subject to
any order, judgment, writ, decree or ruling of any court, arbitration board or
other administrative tribunal which prohibits the execution and delivery or the
performance by such Other Party of the Reimbursement Agreement, the Collateral
Trust Indenture or the Transaction Document or Refinancing Document to which it
is a party.

      Based on the foregoing, I am of the opinion that:

      (1) The Company is a corporation presently subsisting under the laws of
the Commonwealth of Pennsylvania and has the corporate power and authority to
carry on its business as presently conducted, to own or hold under lease its
properties and to enter into and perform its obligations under
<PAGE>
 
                                                                               4


the Reimbursement Agreement, the Collateral Trust Indenture and each Transaction
Document and Refinancing Document to which it is a party.  The Company has not
failed to qualify to do business or to be in good standing in any other
jurisdiction where the failure so to qualify or be in good standing would
materially and adversely affect the financial condition of the Company or its
ability to perform any of its obligations under the Reimbursement Agreement, the
Collateral Trust Indenture or the Transaction Documents or Refinancing Documents
to which it is a party.

      (2) The execution, delivery and performance by the Company of the
Reimbursement Agreement, the Collateral Trust Indenture and each Transaction
Document and Refinancing Document to which it is a party, the consummation by
the Company of the transactions contemplated thereby and the compliance by the
Company with the terms and provisions thereof have been duly authorized by all
necessary corporate action on the part of the Company, and neither such
execution, delivery and performance nor such consummation and compliance
requires the consent or approval of the shareholders of the Company or of any
trustee or holder of any Indebtedness of the Company, other than such consents
and approvals as have been or, on or before the relevant Refunding Date in the
case of any Refunding Loan, will have been duly obtained, given or accomplished.

      (3) The Reimbursement Agreement, the Collateral Trust Indenture and the
Transaction Documents and Refinancing Documents to which the Company is a party
have been duly executed and delivered by the Company.  To the extent that a
Pennsylvania court were to apply the substantive laws of the Commonwealth of
Pennsylvania to the Reimbursement Agreement, the Collateral Trust Indenture or
any Transaction Document or Refinancing Document to which the Company is a
party, the Reimbursement Agreement, the Collateral Trust Indenture or such
Transaction Document or Refinancing Document, as the case may be, would under
such laws constitute the legal, valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms, except as such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or similar laws affecting
creditors' rights generally and by applicable laws and legal and equitable
principles which may affect certain of the remedies provided therein, which laws
and principles do not in my opinion make the remedies provided therein
inadequate for the realization of the substantive benefits and security provided
thereby.

      (4) The execution, delivery and performance by the Company of the
Reimbursement Agreement, the Collateral Trust Indenture and the Transaction
Documents and Refinancing Documents to which it is a party, the consummation by
the Company of the transactions contemplated thereby

and compliance by the Company with the provisions thereof do not conflict with,
or result in a breach or contravention of any of the provisions of, the Restated
Articles of Incorporation or By-Laws of the Company or any Affiliate of the
Company, any Applicable Law, or any indenture, mortgage, lease or other material
agreement or instrument known to me (after due inquiry) to which the Company or
any Affiliate of the Company is a party or by which the property of the Company
or any Affiliate of the Company is bound, or result in the creation or
imposition of any Lien (other than Permitted Liens) upon any property of the
Company or any Affiliate of the Company.

consummation by the Company of the transactions contemplated by, and compliance
by the Company with the terms and provisions of, the Reimbursement Agreement,
the Collateral Trust Indenture and the Transaction Documents and Refinancing
Documents to which it is a party have been duly authorized by the PPUC Orders;
each of the PPUC Orders is in full force and effect on the date hereof without
amendment or modification; there has been no stay or suspension of any PPUC
Order by any court having jurisdiction with respect thereto; no suit, action or
proceeding is pending or, to my knowledge, threatened in which an appeal from
any PPUC Order or any review thereof is being sought; and reversal or
modification of any PPUC Order will not impair or divest any estate or interest
of any Other Party acquired under the Reimbursement Agreement, the Collateral
Trust Indenture or any of the Transaction Documents or Refinancing Documents to
which the Company is a party.

      (7) Except as disclosed in the Company's December 31, 1993 Annual Report
on Form 10-K, its June 30, 1994 Quarterly Report on Form 10-Q and its Current

pending or, to the best of my knowledge, threatened action or proceeding
affecting the Company or any of its Affiliates before any court, governmental
agency or arbitrator having jurisdiction which questions the validity or
enforceability of the Reimbursement Agreement, the Collateral Trust Indenture or
any Transaction Document or Refinancing Document to which it is a party or which
(individually or in the aggregate) if decided adversely to the Company would
have a material adverse effect on the business or financial condition of the
Company or would materially and adversely affect the ability of the Company to
perform its obligations under the Reimbursement Agreement, the Collateral Trust
Indenture or any Transaction Document or Refinancing Document to which it is a
party.

      (8) None of the Administrating Banks or the Banks will be or become,

               FORM OF OPINION OF SPECIAL COUNSEL FOR THE COMPANY


[Date of Issuance of the
 Letters of Credit]



To each of the Participating Banks
 parties to the Reimbursement Agreement
 referred to below, to Swiss Bank Corporation,
 New York Branch, as LOC Bank, and to Union
 Bank and Swiss Bank Corporation, New York
 Branch, as Administrating Banks


                             Duquesne Light Company


Ladies and Gentlemen:

      We have acted as special counsel for Duquesne Light Company, a
Pennsylvania corporation (the "Company"), in connection with the execution and
delivery by the Company of the Reimbursement Agreement, dated as of October 1,
1994 (the "Reimbursement Agreement"), among the Company and yourselves.  All
capitalized terms used herein and not otherwise defined herein shall have the
meanings set forth in the Reimbursement Agreement.  This Opinion is being
delivered pursuant to Section 7(a)(i)(B) of the Reimbursement Agreement.

      As such counsel we have examined originals or copies, certified or
otherwise identified to our satisfaction, of the Reimbursement Agreement, the
Collateral Trust Indenture, the Transaction Documents, the Refinancing Documents
and such corporate records, agreements and other instruments, certificates,
opinions, correspondence with public officials, certificates of officers,
management personnel and representatives of the Company, and such other
documents as we have deemed necessary or desirable for the purpose of rendering
the opinions set forth herein.

      Based on the foregoing, and subject to the qualifications set forth below,
we are of the opinion that:
<PAGE>
 
                                                                               2

      1.  The Reimbursement Agreement, the Collateral Trust Indenture and the
Transaction Documents and Refinancing Documents to which the Company is a party
have been duly executed and delivered by the Company and, assuming the due
authorization, execution and delivery thereof by the other parties thereto, the
Reimbursement Agreement, the Collateral Trust Indenture and the Transaction
Documents and Refinancing Documents to which the Company is a party constitute
the legal, valid and binding obligations of the Company, enforceable against the
Company in accordance with their respective terms.

      2.   Neither the execution, delivery or performance by the Company of the
Reimbursement Agreement, the Collateral Trust Indenture or any Transaction
Document or Refinancing Document to which it is a party, nor the consummation by
the Company of the transactions contemplated thereby, nor compliance by the
Company with the provisions thereof, conflicts with, or results in a breach or
contravention of any of the provisions of, the Restated Articles of
Incorporation or By-laws of the Company, or any Applicable Law.

      3.   No Governmental Action under any law:

           (a) was required with respect to the execution and delivery of the
      Collateral Trust Indenture, each Transaction Document to which the Company
      is a party, each Refinancing Document to which the Company is a party,
      Amendment No. 1 to the Participation Agreements dated as of December 1,
      1987, Amendment No. 2 to the Participation Agreements dated as of March 1,
      1988, Amendment No. 3 to the Participation Agreements dated as of November
      15, 1992, Amendment No. 4 to the Participation Agreements dated as of
      October 13, 1994, Amendment No. 1 to Facility Leases dated as of December
      1, 1987, Amendment No. 2 to Facility Leases dated as November 15, 1992,
      Amendment No. 3 to Facility Leases dated as of October 13, 1994, or the
      First Supplemental Indenture to Collateral Trust Indenture dated as of
      November 15, 1992, or

           (b) is required in connection with the execution and delivery by the
      Company of the Reimbursement Agreement or in connection with the
      performance by the Company of, or the consummation by the Company of the
      transactions contemplated by the Reimbursement Agreement, the Collateral
      Trust Indenture (as amended or supplemented prior to the date hereof as
      set forth above) or any Transaction Document or Refinancing Document to
      which the Company is a party (as amended or supplemented prior to the date
      hereof as set forth above),
<PAGE>
 
                                                                               3

except such Governmental Actions (i) as have been duly obtained, given or
accomplished, (ii) as are routine in nature and not yet required and that cannot
be obtained, or are not normally applied for, prior to the time they are
required, (iii) as may be required to be obtained, given or accomplished from
time to time in connection with the maintenance, use, possession, operation or
improvement of Unit 2 or otherwise with respect to Unit 2 and the Company's or
the Operating Agent's involvement therewith, (iv) as may be required in
consequence of any transfer of ownership of any Note or Bond by the Holder
thereof, the beneficial interest in the Trust by the Owner Participant, or the
Undivided Interest by the Owner Trustee, (v) as may be required in consequence
of the issuance, sale or exchange and delivery of any Bonds or other obligations
under and pursuant to any Collateral Trust Indenture, (vi) as may be required by
existing Applicable Law on and after termination or expiration of the Facility
Leases, or (vii) as may be required under any Applicable Law not now in effect.
No Governmental Action is or will be required solely by virtue of the
participation by the Administrating Banks, the LOC Bank or any Participating
Bank in the consummation of the transactions contemplated by the Reimbursement
Agreement to take place on the date hereof except such Governmental Actions (i)
as have been duly obtained, given or accomplished, (ii) as may be required by
Applicable Law not now in effect, or (iii) as may be required in consequence of
any transfer or assignment by either Administrating Bank, the LOC Bank or any
Participating Bank of its rights under the Reimbursement Agreement, including,
without limitation, any grant of a participation in such rights.

      4.   Neither the LOC Bank, either Administrating Bank nor any
Participating Bank will be or become, solely by reason of its entering into the
Reimbursement Agreement, subject to regulation as an electric utility company,
an electric utility, a public utility company or corporation, a public utility,
a holding company, a public utility holding company, an electric corporation, or
a utility company or corporation by any public utility commission or other
regulatory body, authority or group (including, without limitation, the SEC and
the FERC).

      5.   The Company is not an "investment company", or a company "controlled"
by an "investment company", within the meaning of the Investment Company Act.

      The opinions set forth above are subject to the qualifications that (i)
enforceability of the Reimbursement Agreement, the Collateral Trust Indenture,
the Transaction Documents and the Refinancing Documents in accordance with their
respective terms may be limited by bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance or other similar laws affecting enforcement of
creditors' rights generally, as well as
<PAGE>
 
                                                                               4

general principles of equity and the availability of equitable remedies, and
(ii) certain laws and judicial decisions may affect the enforceability of
certain rights and remedies provided in the Transaction Documents.  With respect
to the latter qualification, however, we are of the opinion that none of such
laws now in effect and none of such judicial decisions make the rights and
remedies provided in the Transaction Documents, taken as a whole, inadequate for
the realization of the intended benefits of the Transaction Documents.  In
addition, to the extent that the provisions of Section 22 of the Reimbursement
Agreement or any indemnification agreement of the Company under any Transaction
Document or Refinancing Document purport to indemnify any Person in respect of
Federal or state securities laws, we are not passing upon the enforceability
thereof.

      Each opinion expressed herein is limited to the law of the State of New
York and the Federal law of the United States of America and each reference
herein to any Governmental Actions refers solely to Federal or New York
Governmental Actions; however, we express no opinion as to any matter relating
to the Atomic Energy Act, the Nuclear Waste Act or any Applicable Law concerning
the regulation of banks.

                          Very truly yours,

                 FORM OF OPINION OF SPECIAL NUCLEAR REGULATORY
                      COMMISSION COUNSEL FOR THE COMPANY



[Date of Issuance of the
Letters of Credit]



To each of the Participating Banks
 parties to the Reimbursement Agreement
 referred to below, to Swiss Bank Corporation,
 New York Branch, as LOC Bank, and to Union
 Bank and Swiss Bank Corporation, New York
 Branch, as Administrating Banks


                             Duquesne Light Company


Ladies and Gentlemen:

      We have acted as Special Nuclear Regulatory Commission Counsel for
Duquesne Light Company (the "Company") in connection with the transactions
contemplated by the Participation Agreements, dated as of September 15, 1987, as
amended by Amendment No. 1 dated as of December 1, 1987, Amendment No. 2 dated
as of March 1, 1988, Amendment No. 3 dated as of November 15, 1992, and
Amendment No. 4 dated as of October 13, 1994 (as so amended, the "Participation
Agreements"), among the Owner Participants, the Company and the other parties
identified in the Participation Agreements, and in connection with the
transactions contemplated by the Reimbursement Agreement, dated as of October 1,
1994 (the "Reimbursement Agreement"), among the Company and yourselves.  All
capitalized terms used herein and not otherwise defined herein shall have the
meanings set forth in the Reimbursement Agreement.  This opinion is being
delivered pursuant to Section 7(a)(i)(C) of the Reimbursement Agreement.
<PAGE>
 
                                                                               2

      We have been requested to give our opinion with respect to five related
issues:  (1) whether Amendment No. 1 to Facility Operating License No. NPF-73
for the Beaver Valley Power Station, Unit No. 2 (the "Amendment"), issued by the
Nuclear Regulatory Commission ("NRC" or the "Commission") on September 23, 1987
and supplemented by NRC letter dated September 28, 1987, which authorized the
Company to proceed with the proposed transactions, is valid and binding and
constitutes final and unappealable NRC action; (2) whether any other action by,
or filing with, the NRC is required in connection with the execution, delivery
and performance of the Reimbursement Agreement; (3) whether any further NRC
action is necessary to maintain the non-licensee status of the LOC Bank, the
Administrating Banks and the Participating Banks; (4) whether the LOC Bank, the
Administrating Banks or the Participating Banks have any licensing or reporting
obligations during the Lease Term under any nuclear-related statute or
regulation; and (5) whether the Price-Anderson Act, 42 U.S.C. (S) 2210, protects
the LOC Bank, the Administrating Banks and the Participating Banks against
liability with respect to any "nuclear incident" (as defined by the Act) and
whether the Act imposes any financial obligations on the LOC Bank, the
Administrating Banks or the Participating Banks.

      In reaching the opinions on these issues set forth below, we have reviewed
and relied upon the Order issued by the NRC on December 12, 1985, in the Palo
Verde docket,/1/ the SECY-85-367 NRC staff document to which the NRC Order
refers, and the Amendment.  We also have reviewed the BVPS Operating Agreement,
and the Company's application to the NRC for approval of the transactions and
the various materials submitted in support of that application.  Finally, we
have reviewed the relevant Transaction Documents, in particular the
Participation Agreements, Appendix A thereto (Definition of Terms), and the
Facility Leases between each Owner Trustee and the Company, and also the draft
Reimbursement Agreement transmitted to us on [_________ ___], 1994.  We have
assumed for purposes of our opinion that the final version of the Reimbursement
Agreement will not differ materially from the draft version.

      1.   Validity and Effect of the Amendment

      In accordance with NRC practice and regulation, the Amendment was issued
by the NRC's staff without an order from the Commission specifically authorizing
the amendment.  Except for certain special situations not applicable here,
amendments to NRC nuclear facility operating licenses

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

/1/  Arizona Public Service Co. (Palo Verde Generating Station, Unit 1), CLI-85-
     17, 22 N.R.C. 875 (1985).
<PAGE>
 
                                                                               3

can be, and usually are, issued by the NRC staff, through delegation of
authority from the Commission without the requirement for such a specific
Commission order. See 10 C.F.R. (S) 1.43 (1988). See also 42 U.S.C. (S) 5843(b)
(1982). Thus the Amendment is valid and binding unless and until it is removed
or changed by the NRC.

      The Amendment constituted the NRC's final disposition in the matter of the
Company's application for a license amendment authorizing the transactions.  The
Administrative Orders Review Act, 28 U.S.C. (S) 2344, permits "any party
aggrieved" by a final order/2/ to petition for review in the appropriate U.S.
Court of Appeals within sixty days of the order's entry.  Since no person filed
such a petition for review with respect to the Amendment within the sixty-day
period, which is jurisdictional, the Amendment is no longer susceptible to
judicial review.

      Section 2.206 of the NRC Rules of Practice (10 C.F.R. (S) 2.206) provides
that "[a]ny person may file a request for [the appropriate NRC office] to
institute a proceeding pursuant to (S) 2.202 to modify, suspend or revoke a
license, or for such other action as may be appropriate."  This provision would
permit any person to request the NRC staff to reconsider and suspend, revoke or
modify the license or any provisions thereof, including the Amendment.  We are
unaware of the existence of any such request, or of any existing facts or
occurrences that would make such a request likely.  No person sought to contest
the issuance of the Amendment or to request a hearing on the Amendment, and we
are unaware of any opposition to its issuance.

      Similarly, Section 2.202 and 2.204 of the Rules of Practice (10 C.F.R.
(S)(S) 2.202 and 2.204) authorize the NRC to take action of its own accord to
modify, suspend or revoke a license by issuing an order to show cause or an
amendment on notice to the licensee that the licensee may demand a hearing with
respect to the order or amendment.  We are unaware of any initiative by the NRC
to take any such action, or of any existing facts or occurrences that would make
such action likely.

      2.   Other Required Licensing Actions.

      The Amendment authorized the licensee to enter into the transactions in
accordance with representations made in the application for the Amendment, which
application included the submittal of a draft


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

/2/  The Administrative Procedure Act defines "order" as a final disposition of
     an agency in a matter including licensing. 5 U.S.C. (S) 551(6).
<PAGE>
 
                                                                               4

Participation Agreement containing a provision on Financial Support describing
the issuance of letters of credit and the terms of the reimbursement agreement.
In the absence of a specific statement in the Amendment to the contrary, no
further action of the NRC is required in connection with the execution and
delivery of the Reimbursement Agreement.

      For the same reason, no further action by the NRC is required in
connection with the performance of the Reimbursement Agreement so long as such
performance does not constitute "exercising directly or indirectly any control
over the licenses of the BVPS, Unit 2".  Amendment, paragraph 2.  We believe
that the words "control over the licenses" must be limited in construction to
mean such control as would be related to the licensed activities of the
licensees, i.e., control over the authorizations and obligations of the
licensees under the license.  The NRC is authorized to issue licenses and
control licensed activities, and would therefore also have jurisdiction to
prohibit activities of non-licensees which are in contravention of NRC law and
regulations.  It would not have jurisdiction over non-licensees with respect to
activities which do not affect NRC's overall responsibilities to protect the
health and safety of the public and the common defense and security.

      Based on an examination of pertinent NRC documents, we believe that the
Amendment language restricts only activities related to the license and the
protection of public health and safety.  The language in the Amendment is
derived from the Commission's December 12 Order/3/ which in turn referenced and
adopted the NRC staff's position and reasoning in its document SECY-85-367.  The
underpinning of the NRC position, as stated in SECY-85-367, is its perception of
the sale of the Undivided Interest as "simply a step in a transaction involving
the refinancing of capital, and where the investor owner only serves in a
passive role with no authority or control over the nuclear facility, the Staff
                  -------------------------------------------------           
can perceive of no regulatory purpose which would be served by an interpretation
of Section 101 of the Atomic Energy Act, which requires the licensing of such
financial investors. . . ." (emphasis added).

      In arriving at its determination that the lessors need not be licensed,
the NRC drew a parallel between the sale-leaseback transaction and a transaction
involving a secured creditor.  NRC's "Creditor Regulations", 10 C.F.R. (S)
50.81, provide that a creditor secured by mortgage, pledge or other


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

/3/  The Commission's Order used the phrase "control over the licensee" while
     the instant Amendment refers to "control over the license". As discussed
     above, we believe that control over the licensee means, in context, control
     over licensed activity, and therefore that the Commission's Order and the
     Amendment contain the identical substantive proscription.
<PAGE>
 
                                                                               5

lien upon a nuclear facility need not be a licensee if the secured creditor
exercises its rights in compliance with and subject to NRC law and regulations
and the restrictions applicable to the facility licensee.  One such regulation
mandates a license condition which prohibits a licensee from transferring any
rights under its license, ". . . directly or indirectly, through transfer of
control of the license to any person  . . ." without NRC approval.  10 C.F.R.
(S) 50.54(c).  Taken together, sections 50.54(c) and 50.81 prohibit a licensee
from transferring its rights under a license, or control of the license, to an
unlicensed secured creditor, and prohibit the unlicensed secured creditor from
taking possession of its secured interest in a nuclear facility or otherwise
exercising control over the activities authorized or required by the license.

      The Amendment specifically states that "[f]or purposes of this condition
[limiting the lessor from exercising control over the licenses,] the limitations
in 10 C.F.R. 50.81 . . . are fully applicable to the lessor . . ."  It is thus
reasonable to conclude that, if the lessor does not take possession of the
Undivided Interest and is in compliance with the provisions of 10 C.F.R. (S)
50.81, the existence and the exercise of the provisions in the Reimbursement
Agreement are not inconsistent with the Amendment's prohibition of "exercising
directly or indirectly any control over the licenses."  The LOC Bank, the
Administrating Banks and the Participating Banks have even less ability to
exercise control over the license during normal performance of the transaction;
and thus, unless the Banks at some point in the future obtain and take
possession of a secured interest in the facility, there is no need for further
licensing.  Under present conditions, no other action by the NRC is required in
connection with the performance of the Reimbursement Agreement.

      No other filing with the NRC is required in connection with the execution
and delivery of the Reimbursement Agreement.  With respect to performance, no
other filing is required unless (a) the performance entails exercise of a
condition in such a manner as to exercise "directly or indirectly control over
the licenses," as discussed above, or (b) a filing is necessary to satisfy the
notification requirements in the Amendment.  Those requirements are that the
lessee (licensee) must "notify the NRC in writing prior to any change in:  (i)
the terms or conditions of any lease agreements executed as part of this
transaction, (ii) the BVPS Operating Agreement, (iii) the existing property
insurance coverage for the BVPS, Unit 2, and (iv) any action by the lessor or
others that may have an adverse effect on the safe operation of the facility."

      3.   Actions Required to Maintain Non-licensee Status

      Unless the LOC Bank, Administrating Banks or Participating Banks seek to
engage in an activity which the NRC deems to be exercising control over the
licenses, no action is necessary under the Amendment as it now exists to
maintain their status as non-licensees.  In the event a person or the NRC should
question or challenge the continued right of the LOC Bank, the Administrating
Bank and the Participating Banks to maintain their non-licensed status, the
Banks may wish to take actions in their defense.  We are unaware of any existing
facts or circumstances which the NRC would deem to be exercising control over
the licenses.

      4.   License and Reporting Obligations of the LOC Bank, the Administrating
           Banks and the Participating Banks

      The Amendment includes the condition that the "lessor and anyone else who
may acquire an interest under these transactions are prohibited from exercising
directly or indirectly any control over the licenses of the BVPS, Unit 2," and
therefore concludes that the sale-leaseback transactions "shall have no effect
on the license for the Beaver Valley facility throughout the term of the
license."  The SECY-85-367 staff recommendation adopted by the Commission's
December 12, 1985 Order further states:

        [W]here as here, the sale of the facility is simply a step in a
      transaction involving only the refinancing of capital, and where the
      investor owner only serves in a passive role with no authority or control
      over the nuclear facility, the Staff can perceive of no regulatory purpose
      which would be served by an interpretation of Section 101 of the Atomic
      Energy Act [the source of the NRC's licensing authority], which requires
      the licensing of such financial investors . . .

      The effect of this analysis, the NRC Order, and the Amendment is that the
LOC Bank, the Administrating Banks and the Participating Banks are not required
to become licensees during the Lease Term and therefore will incur no obligation
as licensees during that period.  By the same token, we believe that the Company
as lessee of the Undivided Interest from the Owner Trustee, will remain during
the Lease Term the relevant licensee under Facility Operating License No. NPF-73
subject to all applicable license obligations with respect to the management and
operation of BVPS Unit 2.  Such licensee obligations include the costs and
responsibilities of decommissioning the facility.
<PAGE>
 
                                                                               7

      In addition, it is our opinion that the LOC Bank, the Administrating Banks
and the Participating Banks have no reporting obligations during the Lease Term
under any nuclear-related law or regulation.  With one exception, such reporting
obligations are limited to licensees or holders of construction permits for
nuclear facilities.  The exception is Section 206 of the Energy Reorganization
Act of 1974, 42 U.S.C. (S) 5846, which provides that each director and
"responsible officer" of any firm "constructing, owning, operating, or supplying
the components of any facility or activity which is licensed or otherwise
regulated" by the NRC, "who obtains information reasonably indicating that such
facility or activity or basic components supplied to such facility" fails to
comply with nuclear laws or regulations relating to substantial safety hazards
or contains a defect that could create a substantial safety hazard, shall
immediately notify the NRC of the failure to comply or the defect.  Although the
literal language of Section 206 would encompass even unlicensed owners of
nuclear facilities, the NRC regulations implementing this provision (10 C.F.R.
Part 21) make clear that its reporting requirements extend only to licensees and
to firms (including directors and responsible officers thereof) that construct,
or supply basic components to, licensed facilities.  10 C.F.R. (S) 21.2.  Just
as the NRC Order in this case reflects the Commission's understanding that the
language of Section 101 of the Atomic Energy Act does not require licensing of
the passive investor owner for its ownership interest in a nuclear facility,
Part 21 of the NRC Regulations reflects the Commission's understanding that the
reporting requirements established by Section 206 were not intended to reach
passive investors or lenders and make sense only if applied to those persons
actually involved in the management, operation or construction of a nuclear
facility or in the supply of basic components for such facilities.  Accordingly,
it is our opinion that neither Section 206 nor its implementing regulations
would impose any reporting requirements on the LOC Bank, the Administrating
Banks or the Participating Banks during the Lease Term.

      5.   The Price-Anderson Act

      Section 170 of the Price-Anderson Act, in its present form, requires
"licensees" of nuclear facilities to maintain financial protection in specified
amounts against "public liability" for "nuclear incidents" (as that term is
defined in the Price-Anderson Act, 42 U.S.C. (S) 2014(q)), which protection
includes mandatory insurance coverage, retroactive premium assessments, and
surcharges.  42 U.S.C. (S) 2210(a), (b), & (o)(1)(E).  The Price-Anderson Act
also protects all "persons indemnified" against public liability for nuclear
incidents beyond the sum of the amount covered by the required financial
protection (including surcharges) and the limits of indemnification provided by
the NRC, 42 U.S.C. (S) 2210(e), but does not preclude Congress from enacting
revenue measures applicable to NRC licensees to fund actions for
<PAGE>
 
                                                                               8

full compensation of all public liability claims, 42 U.S.C. (S) 2210(e)(3).  The
Act defines the term "person indemnified" to include both persons who are
required to maintain financial protection, i.e., licensees, and "any other
person who may be liable for public liability."  42 U.S.C. (S) 2014(t).  The
term "public liability," in turn, is defined to mean "any legal liability
                                                      ---                
arising out of or resulting from a nuclear incident or precautionary evacuation"
(emphasis added), except for workers' compensation claims of persons employed at
the site where the incident occurs, claims arising out of an act of war, and
claims relating to loss of, or damage to, or loss of use of property located at
the site of and used in connection with the activity where the incident occurs.
42 U.S.C. (S) 2014(w).

      In light of the Amendment holding that the Company remains the licensee of
the BVPS, Unit 2 during the Lease Term, in our opinion the LOC Bank, the
Administrating Banks and the Participating Banks will have no obligation under
the Price-Anderson Act or its implementing regulations to maintain financial
protection during the Lease Term.  In addition, the terms of the Act described
above extend full financial protection to the Banks against public liability for
nuclear incidents.

                                     * * *

      In summary, it is our opinion that: (1) the Amendment is valid and binding
subject only to reconsideration at the initiative of the NRC or some other
person under Sections 2.202, 2.204 or 2.206 of the NRC's Rules of Practice; (2)
no further action by the NRC is required in connection with the execution,
delivery and performance by the Company of the Reimbursement Agreement so long
as the conditions of the Amendment are adhered to, and no further filing with
the NRC is required except as required by the conditions of the Amendment; (3)
no further action by the NRC is required to maintain the non-licensee status of
the LOC Bank, the Administrating Banks and the Participating Banks; (4) under
the terms of the NRC Order and under a proper reading of Section 101 of the
Atomic Energy Act and its implementing regulations in their present form, the
LOC Bank, the Administrating Banks and the Participating Banks do not have any
license or reporting obligations during the Lease Term under any nuclear-related
law or regulation; and (5) the Price-Anderson Act in its present form protects
the LOC Bank, the Administrating Banks and the Participating Banks against
financial exposure from any liability for nuclear incidents and does not require
the Banks to maintain financial protection during the Lease Term against
liability for such nuclear incidents.

                FORM OF OPINION OF SPECIAL NEW YORK COUNSEL FOR
                   THE LOC BANK AND THE ADMINISTRATING BANKS



[Date of Issuance of the
 Letters of Credit]



To the Persons listed on Schedule A
 hereto



                             Duquesne Light Company


Ladies and Gentlemen:

      We have acted as special New York counsel to Swiss Bank Corporation,
acting through its New York Branch (the "LOC Bank"), in connection with the
preparation, execution and delivery of the Reimbursement Agreement, dated as of
October 1, 1994 (the "Reimbursement Agreement"), among Duquesne Light Company
(the "Company"), the LOC Bank, Union Bank and Swiss Bank Corporation, New York
Branch, as the administrating banks (the "Administrating Banks"), and the
Participating Banks named therein, and the issuance by the LOC Bank of its
Irrevocable Transferable Letters of Credit Nos. S546733, S546734, S546735,
S546736, S546737, S546738 and S546739, each dated October ___, 1994 (the
"Letters of Credit").  Capitalized terms used herein, unless otherwise defined,
shall have the meanings set forth in the Reimbursement Agreement.

      As such counsel, we have examined the originals, or copies identified to
our satisfaction, of the Reimbursement Agreement and the Letters of Credit and
such other certificates, documents, agreements and instruments as we have deemed
necessary as a basis for the opinions hereinafter expressed.  As to questions of
fact material to such opinions, we have relied, without independent
investigation, on such records, certificates, documents, agreements and
instruments.

      Our opinions expressed below are limited to the law of the State of New
York and the Federal law of the United States of America, and we do not
<PAGE>
 
                                                                               2

express any opinion herein concerning any other law.  With respect to matters
dependent on Swiss law, we have, with your permission, assumed the correctness
of, have made no investigation of the matters covered by, and our opinion is in
all respects subject to the conditions and qualifications set forth in, the
opinion dated the date hereof of Oskar Morikofer, Swiss counsel to Swiss Bank
Corporation, a copy of which is attached hereto.  Further, we express no opinion
as to the applicability of, or any party's compliance with, the Federal
securities laws or any state securities or "blue sky" laws.

      Based upon and subject to the foregoing, and subject to the exceptions,
qualifications and assumptions set forth herein, we are of the opinion that:

           1.  The LOC Bank is duly licensed by the Superintendent of Banks of
      the State of New York as a New York branch of Swiss Bank Corporation, in
      accordance with the provisions of Article V of the Banking Law of the
      State of New York (the "New York Banking Law").  The LOC Bank has the
      power and authority under Article V of the New York Banking Law to issue
      the Letters of Credit.

           2.  Each of the Letters of Credit has been duly issued, executed and
      delivered and constitutes the valid and legally binding obligation of the
      LOC Bank, enforceable against the LOC Bank in accordance with its terms,
      except as such enforcement may be limited by (a) applicable bankruptcy,
      composition, receivership, conservatorship, insolvency, reorganization,
      moratorium, liquidation, readjustment of debt or similar laws affecting
      the enforcement of the rights of creditors generally as such laws may be
      applied in the event of any bankruptcy, composition, receivership,
      conservatorship, insolvency, reorganization, moratorium, liquidation,
      readjustment of debt or similar proceeding relating to the LOC Bank or its
      assets, and (b) general principles of equity (regardless of whether such
      enforceability is considered in a proceeding in equity or at law).

              3.  Upon proper and timely presentation to the LOC Bank of a draft
      and other documents in strict conformity with a Letter of Credit, the LOC
      Bank would be obligated to honor the draft in accordance with the terms of
      such Letter of Credit, notwithstanding any bankruptcy, insolvency,
      reorganization, moratorium, liquidation, readjustment of debt or similar
      proceeding relating to the Company or its assets.  We point out, however,
      that bankruptcy courts are courts of equity and that, in the exercise of
      their equity powers, courts have in the past in certain circumstances
      temporarily restrained and preliminarily enjoined payments under letters
      of credit.  However, in our opinion, any such proceeding would not, in and
      of itself, be the proper basis for a court to enjoin permanently such
      payment.

                                                                               3

           4. In the event that a final, conclusive and enforceable judgment
      granting recovery of a sum of money (other than a judgment for taxes, a
      fine, or other penalty) is rendered by a Swiss court against Swiss Bank
      Corporation based on any Letter of Credit, the courts of the State of New
      York would recognize such judgment pursuant to Section 5303 of the New
      York Civil Practice Law and Rules, except as provided in Section 5304 of
      the New York Civil Practice Law and Rules.

           5.  The execution, delivery and performance by the LOC Bank of the
      Letters of Credit do not violate any law, rule or regulation applicable to
      the LOC Bank, except for such violations if any as do not adversely affect
      (a) the enforceability of each Letter of Credit against the LOC Bank in
      accordance with its terms or (b) the obligation of the LOC Bank to honor
      any draft in accordance with the terms of a Letter of Credit upon proper
      and timely presentation thereof, together with other documents, to the LOC
      Bank in strict conformity with such Letter of Credit.

           6.  The Courts of the State of New York may properly exercise
      personal jurisdiction over the LOC Bank in an action or proceeding arising
      out of a default in the performance by the LOC Bank of its obligations
      under a Letter of Credit, and such personal jurisdiction in respect of the
      LOC Bank would continue notwithstanding the failure of the LOC Bank to
      maintain an office in the State of New York.

                                               Very truly yours,

               FORM OF OPINION OF SWISS COUNSEL FOR THE LOC BANK


                                                          TO EACH OF THE PERSONS
                                                          LISTED IN SCHEDULE A
                                                          ATTACHED HERETO


Dear Sirs:

I am a Legal Adviser and a First Vice President of Swiss Bank Corporation (the
"Bank") and I am a member in good standing of the Bar of the Canton of Thurgau,
Switzerland.  With respect to the Reimbursement Agreement (the "Reimbursement
Agreement"), between the Bank's New York Branch (the "Branch") as LOC Bank,
Duquesne Light Company, Union Bank and the Branch, as Administrating Banks, and
the Participating Banks named therein, pursuant to which the Branch has issued
Letters of Credit Nos. S546733, S546734, S546735, S546736, S546737, S546738 and
S546739 (the "Letters of Credit"), I have examined or have had examined
originals or copies of such documents, corporate records and other instruments
as I have deemed necessary or advisable for purposes of this opinion.  In
rendering this opinion I have relied as to certain matters on information
obtained from public records, officers of the Bank and other sources believed by
me to be responsible and have assumed that the signatures on all documents
examined by me are genuine, an assumption which I have not independently
verified.

Based upon the foregoing, I am of the opinion that:

      1.   The Bank is a banking corporation duly organized and validly existing
           under the laws of Switzerland and the Bank has the corporate power
           under Swiss law to execute, deliver and perform the Letters of
           Credit.  The Bank is a private corporation not affiliated with the
           Swiss government and is subject to the jurisdiction of Swiss courts
           on the same basis as other private corporations.

      2.   Each Letter of Credit has been duly authorized by the Bank and,
           assuming that each Letter of Credit constitutes the legal, valid and
           binding obligation of the Bank, acting through the Branch, in
           accordance with New York law, it will, when duly executed and
           delivered by the Branch, constitute the legal, valid and binding
           obligation of the Bank enforceable against the Bank acting through
           the Branch in accordance with its terms.
<PAGE>
 
                                                                               2

      3.   Each Letter of Credit is enforceable in accordance with its terms
           against the Bank's head office in Switzerland if the Branch defaults
           in its obligations under such Letter of Credit or the Bank ceases to
           have a presence in New York.

      4.   The choice of the law of the State of New York to govern the Letters
           of Credit is valid under the laws of Switzerland and a court in
           Switzerland would uphold such choice of law in a suit or other
           proceeding on such Letter of Credit brought in a court of
           Switzerland, provided that the application of such law to the case
           would not result in a contravention of Swiss public policy.

      5.   Any final and conclusive judgement for a fixed and definite sum
           obtained against the Branch in any competent U.S. Federal or State
           court having jurisdiction over the Branch in respect of any suit,
           action or proceeding against the Branch for the enforcement of any
           Letter of Credit will, upon request, be declared valid and
           enforceable against the Bank by the competent courts at the legal
           domicile of the Bank in Basel, Switzerland, without relitigation of
           the matters adjudicated, provided that its contents are not contrary
           to, and the judgement has not been rendered in violation of, Swiss
           public policy and provided that due process was not denied and the
           same subject matter was not first brought or earlier adjudicated in
           another court.

      6.   The opinion expressed in paragraphs 2 and 3 are subject to the
           following qualification:  such enforcement may be limited by
           bankruptcy, insolvency, liquidation, reorganization, moratorium or
           other similar laws affecting the rights of creditors against the Bank
           generally, from time to time in effect, as the same would apply in
           the event of the bankruptcy, insolvency, liquidation or
           reorganization of, or other similar occurrence with respect to, the
           Bank or in the event of a moratorium or similar occurrence affecting
           the Bank.

      7.   With respect to paragraphs 4 and 5 of this opinion it can be stated
           as a general rule that judgements of U.S. Federal courts and courts
           of the State of New York rendered in application of the law of the
           State of New York are enforceable in Switzerland and, with the
           exception of judgements awarding treble or punitive damages or
<PAGE>
 
                                                                               3

           judgements rendered against a defendant domiciled outside the U.S.A.
           upon whom service of process or of pleadings was not made by way of
           legal assistance by the local authorities, I know of no reason why
           such judgements would be a violation of Swiss public policy or the
           rules of due process of law prevailing in Switzerland.

      8.   The obligations of the Bank under the Letters of Credit rank pari
           passu with all deposits and other unsecured obligations of the Bank,
           except that the bankruptcy law of Switzerland provides for a number
           of priorities, the most material of which are (a) employment wage
           claims, (b) social security claims and (c) the claims of "savings
           depositors" in the amount of up to 10,000.-- Swiss Francs per
           depositor.

      9.   No license, consent or approval of, or registration with, any
           governmental department, agency, commission or regulatory authority
           of Switzerland is required in connection with the execution, delivery
           or performance of the Letters of Credit by the Bank, acting through
           the Branch, to make each Letter of Credit fully enforceable in
           accordance with its respective terms.

      10.  No stamp duty or similar tax is currently payable to any governmental
           authority in Switzerland in respect of the issuance, execution,
           delivery or effectiveness of the Letters of Credit, and the Bank is
           not required to make any deduction or withholding from any payment it
           may make thereunder.

I express no opinion as to any matters governed by any laws other than the laws
of Switzerland.

This opinion may not be used or relied upon by or published or communicated to
any party other than the addressees hereof for any purpose whatsoever without my
prior written approval in each instance.

                                     Very truly yours,

                          FORM OF ASSIGNMENT AGREEMENT


                         Dated _________________, 19__


      Reference is made to the Reimbursement Agreement, dated as of October 1,
1994 (said Agreement, as it may hereafter be amended or otherwise modified from
time to time, being the "Agreement"; unless otherwise defined herein terms
defined in the Agreement are used herein with the same meaning), among Duquesne
Light Company (the "Company"), Swiss Bank Corporation, New York Branch ("Swiss
Bank Corporation"), as LOC Bank (the "LOC Bank"), Union Bank and Swiss Bank
Corporation, as Administrating Banks, and the Participating Banks named therein
and from time to time parties thereto.  Pursuant to the Agreement,
______________ (the "Assignor") has acquired a participation from the LOC Bank
in and to each Letter of Credit.

      The Assignor and ________________ (the "Assignee") agree as follows:

      1.   The Assignor hereby sells and assigns, without recourse, to the
Assignee, and the Assignee hereby purchases and assumes from the Assignor,
without recourse to the Assignor, that portion set forth in Section 1(c) of
Schedule 1 hereto (the "Assigned Interest") of the Assignor's rights and
obligations under the Agreement, including, without limitation, the
participation acquired by the Assignor pursuant to Section 5 of the Agreement in
respect of unreimbursed amounts owing from time to time to the LOC Bank and
unreimbursed amounts outstanding on the Effective Date.  Such Assigned Interest
represents the percentage interest specified in Section 2(b) of Schedule 1 of
all outstanding rights and obligations of the Participating Banks under the
Agreement, and, after giving effect to such sale and assignment, the Assignee's
and Assignor's Participation Percentages will be as set forth in Sections 2(b)
and 2(c), respectively, of Schedule 1.  The effective date of this sale and
assignment shall be the date specified in Section 3 of Schedule 1 (the
"Effective Date").

      2.   On the Effective Date, the Assignee will pay to the Assignor, in same
day funds, at such address and account as the Assignor shall advise the
Assignee, an amount equal to (1) the aggregate amount of unreimbursed letter of
credit payments outstanding (as set forth in Section 1 of Schedule 1) times (2)
the Assigned Interest.  From and after the Effective Date, the
<PAGE>
 
                                                                               2

Assignor agrees that the Assignee shall be entitled to all rights, powers and
privileges of the Assignor under the Agreement to the extent of the Assigned
Interest, including without limitation (i) the right to receive all payments in
respect of the Assigned Interest for the period from and after the Effective
Date, whether on account of reimbursements, principal, interest, fees,
indemnities in respect of claims arising after the Effective Date, increased
costs, additional amounts or otherwise; (ii) the right to vote and to instruct
the Administrating Banks and the LOC Bank under the Agreement based on the
Assigned Interest; (iii) the right to set-off and to appropriate and apply
deposits of the Company as set forth in the Agreement; and (iv) the right to
receive notices, requests, demands and other communications.  The Assignor
agrees that it will promptly remit to the Assignee any amount received by it in
respect of the Assigned Interest (whether from the Company, the Administrating
Banks or otherwise) in the same funds in which such amount is received by the
Assignor.

      3.   The Assignor (i) represents and warrants that it is the legal and
beneficial owner of the interest being assigned by it hereunder and that such
interest is free and clear of any adverse claim; (ii) makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with the Agreement, the
Transaction Documents, the Financing Documents or the Refinancing Documents or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of the Agreement, the Transaction Documents, the Financing Documents, the
Refinancing Documents or any other instrument or document furnished pursuant
thereto; and (iii) makes no representation or warranty and assumes no
responsibility with respect to the financial condition of the Company or the
performance or observance by the Company of any of its obligations under the
Agreement or under the Transaction Documents, Financing Documents or Refinancing
Documents to which it is, or is to be, a party, or any other instrument or
document furnished pursuant thereto.

      4.   The Assignee (i) confirms that it has received a copy of the
Agreement, together with copies of the financial statements referred to in
Section 10(g) thereof and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into this
Assignment; (ii) agrees that it will, independently and without reliance upon
the Administrating Banks, the LOC Bank, the Assignor or any other Participating
Bank and based on such documents and information as it shall deem appropriate at
the time, continue to make its own credit decisions in taking or not taking
action under the Agreement; (iii) appoints and authorizes the Administrating
Banks to take such action as agents on its behalf and to exercise such powers
under the Agreement as are delegated to the
<PAGE>
 
                                                                               3

Administrating Banks by the terms thereof, together with such powers as are
reasonably incidental thereto; and (iv) agrees that it will perform in
accordance with its terms all of the obligations which by the terms of the
Agreement are required to be performed by it as a Participating Bank.

      5.   Following the execution of this Assignment, it will be delivered to
Union Bank, as Administrating Bank, for acceptance.  Upon such acceptance and
receipt of the consents of the LOC Bank and the Company required pursuant to
Section 23(b) of the Agreement (which shall be evidenced by the LOC Bank's and
the Company's execution of this Assignment on the appropriate spaces on Schedule
1), as of the Effective Date, (i) the Assignee shall be a party to the Agreement
and, to the extent provided in this Assignment, have the rights and obligations
of a Participating Bank thereunder and (ii) the Assignor shall, to the extent
provided in this Assignment, relinquish its rights and be released from its
obligations under the Agreement.

      6.   Upon such acceptance and consent, from and after the Effective Date,
each Administrating Bank and the LOC Bank shall make all payments under the
Agreement in respect of the interest assigned hereby (including, without
limitation, all payments of principal, interest and fees with respect thereto)
to the Assignee at its address set forth on Schedule 1 hereto.  The Assignor and
Assignee shall make all appropriate adjustments in payments under the Agreement
for periods prior to the Effective Date directly between themselves.

      7.   This Assignment shall be governed by, and construed in accordance
with, the laws of the State of New York.

      IN WITNESS WHEREOF, the parties hereto have caused this Assignment to be
executed by their respective officers thereunto duly authorized, as of the date
first above written, such execution being made on Schedule 1 hereto.

                       EXECUTIVE COMPENSATION OF CERTAIN
                        DUQUESNE LIGHT COMPANY EXECUTIVE
                    OFFICERS FOR 1994 AND SECURITY OWNERSHIP
                      OF DUQUESNE LIGHT COMPANY DIRECTORS
                 AND EXECUTIVE OFFICERS AS OF FEBRUARY 16, 1995


REPORT OF THE COMPENSATION COMMITTEE OF THE
BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION

     All components of executive officer compensation were approved by the Board
of Directors based on the recommendations of the Compensation Committee, which
is composed entirely of non-employee directors.

     It is anticipated that in 1995, as in 1994, all compensation to executives
will be fully tax deductible.  It is the present intention of the Committee to
seek to ensure that all compensation payable to executives that is otherwise tax
deductible will continue to be tax deductible; however, the Committee reserves
the right to take whatever action with respect to the compensation of executive
officers that it deems appropriate and in the best interest of the Company and
DQE stockholders.  The Committee will finalize its intention when final tax
regulations are issued under Section 162(m) of the Internal Revenue Code.

     The primary objective of the Compensation Committee is to ensure that
Duquesne Light Company's (Duquesne's) executive compensation programs and
strategies are designed and administered to attract, retain and motivate the
executive talent required to achieve Duquesne's overall mission of creating and
enhancing value for DQE stockholders, customers and employees, as well as for
the community in which it operates.

     The Compensation Committee's actions are governed by a long-standing
philosophy of developing and administering executive compensation programs that
encourage a high level of operational excellence and financial performance to
maximize stockholder value and customer satisfaction.

     The Committee also strives to simultaneously foster community participation
and support quality leadership initiatives and innovative methodologies that
will effectively manage Duquesne's human resources and capital assets.

     Throughout the development and administration of Duquesne's strategic
compensation plans, the Committee has adhered to a results-based approach by
linking a significant percentage of total compensation to meeting performance
objectives.  The three variable components of executive compensation (base
salary, cash incentives and stock options) are based on performance.
<PAGE>
 
     The Committee has purposely placed an emphasis on the "at risk" elements of
compensation for Duquesne's executives.  Duquesne's awards under these incentive
programs are tied to corporate and individual performance.  The accomplishment
of goals and objectives is at the center of the Committee's decision to make
awards under these incentive programs.  The Committee exercises a degree of
discretion in administering these incentive plans which the Committee believes
encourages the executives to continually focus on building long-term stockholder
value.

     An independent outside consultant with significant industry expertise has
determined that a greater percentage of Duquesne's executive officers' total
compensation is variable and placed at risk, when benchmarked against a
comparative industry panel of electric utility companies of similar operating
revenue size.

     The three components of Duquesne's executive compensation program are base
salary, annual cash and stock-option incentives and long-term stock options.
The Company has entered into employment agreements with Messrs. von Schack,
Marshall, and Schwass and Ms. Green pursuant to which the minimum annual base
salary is specified.  All stock options are granted under the Long-Term
Incentive Plan and are performance based.

     Annually, the Committee reviews and determines base salary levels, annual
incentive compensation, and long-term performance-based stock option vesting,
with vesting decisions intended to encourage long-term results that increase
stockholder value.

     Executive officers may or may not earn, on the basis of performance, cash
in the form of adjustments to base salary and annual cash incentives.  Executive
officers also have the opportunity to earn annual performance stock options
under the Long-Term Incentive Plan as described under the caption "Annual
Incentives."  Finally, they have the opportunity to also earn Long-Term
Incentive Plan performance-based stock options under a three-year grant.

     The base salaries of executive officers are competitively benchmarked
against a comparative industry panel of electric utility companies of similar
revenue and operating characteristics.  The Committee's goal is to target base
salaries at the average of the comparative industry panel.

     In addition to the industry panel comparison, the Committee considered 1993
results in the areas of customer service levels, cost-effective management and
operational performance (including, for example, generating plant performance
and system reliability) in determining whether a base salary increase would be
granted to the executive officers in 1994.  The named executive officers, other
than Mr. von Schack and Mr. Beck, received increases in base salary in 1994.

     The executive officers have the opportunity to earn annual cash and stock
option performance awards by meeting short-term operating and financial goals.
Individual objectives are established for each executive officer in consultation
with the CEO and

                                       2
<PAGE>
 
approved by the Compensation Committee.  The Committee reviews the specific
results for each executive officer and the corporate performance with the Board
of Directors during the following year.  The Board of Directors, upon the
recommendation of the Compensation Committee, approves the amount of annual
performance awards granted to each executive officer based on the achievement
of corporate and individual objectives.

     Annual performance awards are granted only if a pre-determined corporate
financial performance threshold is met.  The threshold recommended by the
Compensation Committee and approved by the Board of Directors for 1993 related
to DQE's earnings per share.  This goal was met in 1993.

     Each executive officer must also meet his or her individual annual
objectives.  Specific objectives established in 1993 and considered by the
Committee in 1994 in determining the annual performance compensation awards
earned by the executive officers supported one or more of five major corporate
objectives, including maximizing long-term stockholder value, providing quality
service and superior customer satisfaction, managing assets cost effectively,
maintaining excellent operational performance and providing leadership in the
community.  Assessment of operational performance was based, for example, upon
such measures as generating plant availability and system reliability.

     In the aggregate, cash awards for annual incentives do not exceed 40% of
base salary for the Chief Executive Officer and 30% of base salary for all other
executive officers.  Annual cash incentive awards for executives range from
0-40% of base salary depending upon the degree to which performance objectives
are met.  See the Summary Compensation Table for the annual cash incentive
compensation awards earned by the executive officers for 1993 and paid in 1994.

     The number of performance stock options awarded annually to executive
officers is determined by use of a cash incentive performance multiplier.  The
size of the multiplier is based on the amount of increase in earnings per share
of DQE Common Stock.  In 1994, the Committee awarded annual performance options
in the amount of 44,815 to Mr. von Schack; 15,119 to Mr. Marshall; 16,058 to Mr.
Schwass; 13,931 to Ms. Green; and 9,319 to Mr. Beck.  Additional options were
not earned because not all of the established performance objectives were
achieved (see footnote (3) to the Summary Compensation Table).  The grant
relative to these vested stock options was disclosed in the option grant table
included in the Duquesne Light Company Statement for 10-K for 1994.  Fifty
percent of the annual stock options awarded in 1994 vest upon award.  An
executive must wait one year before being able to exercise the remaining 50%.

     Long-Term Incentive Plan performance-based stock options awarded in 1994
were granted to executive officers in 1991 under the provisions of a three-year
plan recommended by the Compensation Committee and approved by the Board of
Directors.  Three-year strategies were developed by each executive officer and
annual milestones designed to enhance the general well-being of Duquesne were
established for each executive officer by the CEO and approved by the
Compensation Committee.  The long-term strategies are

                                       3
<PAGE>
 
designed to support the long-term corporate objectives of maximizing
stockholder value, providing quality service and superior customer
satisfaction, managing assets cost effectively, maintaining excellent
operational performance and providing leadership in the community.  Through a
performance-based vesting schedule, each executive officer had the opportunity
to earn a percentage of the three-year grant annually.  The Compensation
Committee reviewed the performance results and determined the amount of the
award with the approval of the Board of Directors.  The vesting opportunity was
up to 30% in the first year, up to 60% in the second year, and up to 100% in
the third year.  With respect to third-year vesting for the 1991 Long-Term
Incentive Plan based on achievement of their long-term strategies, Messrs.
von Schack and Schwass, Ms. Green and Mr. Beck received 40% vesting and
Mr. Marshall received 44% vesting.  A new three-year plan was established by
the Compensation Committee in 1994.  The new grants shown in the table
entitled, "Option/SAR Grants in Last Fiscal Year," have the same vesting limits 
and rewards are determined by results.

     As with all executive officers, the Committee reviews the CEO's prior
year's performance when evaluating whether or not a prospective performance
increase is recommended with respect to his base salary and whether awards are
made under the annual cash and stock-option incentive programs and for the long-
term incentive performance-based stock option vesting.

     The CEO's performance is evaluated on the basis of the overall performance
of Duquesne, the performance of the other members of his management team and, as
discussed in more detail below, his leadership in developing and implementing
operating and strategic plans to further Duquesne's long-term corporate
objectives.  Within the parameters of the specific compensation programs
previously discussed, the Committee has the flexibility to exercise a degree of
discretion in evaluating the CEO's total performance.

     The Committee believes that emphasis should be placed on the variable
compensation portion (i.e., incentive cash and stock options) of the CEO's total
compensation (see previous discussion on pages 1 through 4).  Both the Committee
and the Board believe that this strengthens the relationship between corporate
performance and ultimate total compensation for the CEO, thus maximizing
stockholder value.  The Committee, emphasizing the at-risk compensation aspect
of Mr. von Schack's total compensation, has not given him an increase in base
salary since 1992.  His current base salary level is below the average of the
comparative industry panel.

     Under the leadership of the CEO, the management team continued to achieve
excellent results with respect to Duquesne's long-term corporate objectives.  In
1994 DQE and Duquesne continued to demonstrate a solid track record of financial
and operational performance.  DQE's earnings per share increased 26 cents, and
DQE's Common Stock dividends increased eight cents annually.  DQE's common stock
has had a total return which consistently exceeded both the Standard & Poor's
500 and S&P Electric Companies over the same period.  A full report on DQE's
financial performance

                                       4
<PAGE>
 
can be found in the 1994 Annual Report to Stockholders.  These results are
consistent with DQE's stockholder objective to achieve measurable and
meaningful increases in the value of our stockholders' investment.

     Customers continue to rate Duquesne's quality of service significantly
higher than the national utility average, according to independent surveys.
Duquesne's customers also continued to experience service reliability among the
top 25% of U.S. utilities.  Customer rates were reduced on average 8% in April
of last year.  Duquesne's customer service and marketing activities received
outstanding national recognition during 1994, including two national Edison
Electric Institute marketing awards for innovative residential and commercial
marketing activities, four Edison Electric Institute/American Gas Association
"Eagle" awards for outstanding and innovative customer service programs and one
Electric Power Research Institute ("EPRI") "Lighting the Way" Award for
application of EPRI technology.

     Duquesne continues to be widely recognized as an environmental leader.
Some examples of recent environmental accomplishments include successfully
meeting all of the objectives and goals of Duquesne's Environmental Strategic
Plan; completing a comprehensive environmental training program attended by all
Duquesne employees (believed to be a first of its kind); developing an
innovative environmental nitrogen oxide emission control system; and
establishing a Company-wide pollution prevention program to plan, document and
verify Duquesne's continuing efforts to effectively control pollution.  Duquesne
remains fully committed to being an environmentally clean utility and an
innovative and forward-thinking environmental leader into the future.

     The CEO also has taken a strong leadership role in community affairs,
including active participation on boards and committees of various organizations
which focus resources on the most pressing community problems and which serve to
improve the quality of life for people who live and work in Duquesne's service
territory.  These activities and those in the environmental area relate directly
to Duquesne's community objective to be a community leader in improving the
quality of life in our service territory.  The objective recognizes that our
future success is clearly linked to the economic health and vitality of the
region we serve.

     We believe that our existing compensation philosophy has been effective in
attracting and retaining the management talent necessary to ensure a desirable
and consistent performance for stockholders and customers alike.

(1)  No incentive compensation is shown for 1994 since the annual review of
     corporate and individual performance for 1994, which will determine such
     compensation, has not occurred.  The amount of any such compensation is
     determined annually in each year based upon the prior year's performance
     and either paid or deferred (via an eligible participant's prior election)
     in the following year.  The amounts shown for 1992 and 1993 are the awards
     earned in those years but established and paid or deferred in the
     subsequent years.

(2)  Amounts of Other Annual Compensation are connected to the funding of
     service obligations for non-qualified pension benefits due to tax law
     changes and to ERISA requirements.  Amounts of All Other Compensation shown
     are Duquesne Light match contributions during 1992, 1993 and 1994 under the
     Duquesne Light Company 401(k) Retirement Savings Plan for Management
     Employees.

(3)  Includes total number of stock options granted during the fiscal year, with
     or without tandem SARs,

                                       6

     and stock for stock (reload) options on option exercises, as applicable,
     whether vested or not. See table titled Option/SAR Grants in Last Fiscal
     Year. The stock options are subject to vesting (exercisability) based on
     Company and individual performance and achievement of specified goals and
     objectives. Of the original amount of 1992 stock options granted, Messrs.
     von Schack, Marshall, and Schwass, Ms. Green and Mr. Beck have lost 12,435;
     4,698; 3,569; 4,432; and 6,138 stock options, respectively. Of the original
     amount of 1993 stock options granted, Messrs. von Schack, Marshall and Mr.
     Beck have lost 6,107; 939; and 3,388 stock options, respectively.


 Supplemental Tables

     The following tables provide information with respect to options to
purchase DQE Common Stock and tandem stock appreciation rights in 1994 under the
Plan.

     Option grants in 1994 to executives were structured to align their
compensation with the creation of value for common stockholders.  For example,
should DQE stock rise 50% in value over the ten-year option term (from $29.5625
per share to $44.34 per share), stockholder value would increase an estimated
$772,948,043, while the value of the grants to the individuals listed below
would increase an estimated .56% ($4,384,977) of the total gain realized by all
stockholders.

*    The actual value, if any, an executive may realize will depend on the
     difference between the actual stock price and the exercise price on the
     date the option is exercised.  There is no assurance that the value
     ultimately realized by an executive, if any, will be at or near the value
     estimated.

(1)  The performance stock options with tandem stock appreciation rights granted
     during 1994 are not presently exercisable.  The Compensation Committee will
     determine the number of stock option/stock appreciation rights that will
     vest in 1995 based on 1994 performance.  Once the number is

                                       7
<PAGE>
 
     determined, 50% of the award vests immediately and the remaining 50% vests
     one year later. Vesting will be accelerated on the occurrence of a change
     in control as provided in the Plan. These grants included tandem stock
     appreciation rights but not dividend equivalents.

(2)  These grants represent performance stock options with dividend equivalents.
     Awards are made over a three-year period and are determined on the basis of
     individual achievement of strategic goals and objectives.

(3)  The exercise price of the options is the fair market value of DQE Common
     Stock on the date such options were granted.  The exercise price may be
     payable in cash or previously owned shares of DQE Common Stock.

(4)  The grant date present value shown in column (f) gives the theoretical
     value of the options listed in column (b) on the grant dates using the
     Black-Scholes option pricing model, modified to account for the payment of
     dividends.  The theoretical value of the options expiring on March 21, 2004
     ($32.00 exercise price) and August 29, 2004 ($30.50 exercise price) was
     calculated assuming an option life of ten years; a periodic risk-free rate
     of return equal to the yield of the U.S. Treasury note having a similar
     maturity date as the option expiration date, as reported on the grant date
     (6.43% and 7.20%, respectively); a quarterly dividend of $0.42 as of the
     option grant date, with an expected growth rate of 4.5% per year as
     estimated by "Value Line"; and an expected stock price volatility over the
     same length of time as the option life, as reported on the grant date
     (17.87% and 17.79% per month, respectively).  No adjustments to the grant
     date present values have been made with respect to exercise restrictions,
     cancellation, or early exercise.

</TABLE>

     Compensation utilized for pension formula purposes includes salary and
bonus reported in columns (c) and (d) of the Summary Compensation Table.  An
employee who has at least five years of service has a vested interest in the
retirement plan.  Benefits are received by an employee upon retirement, which
may be as early as age 55.  Benefits are reduced by reason of retirement prior
to age 60 or by reason of the operation of certain options under which benefits
are payable to survivors upon the death of the employee.  Pension amounts set
forth in the above table reflect the integration with social security of the
tax-qualified retirement plans.  Retirement benefits are not subject to any
other offset or reduction based on the amount of any other benefits.

     The executive officers named in the Summary Compensation Table had the
following whole years of credited service and five-year covered compensation
with Duquesne and its affiliates (including additional service credits and
compensation recognized under supplemental pension arrangements) as of January
1, 1995:  Mr. von Schack - 28 years,

                                       9
<PAGE>
 
current five-year covered compensation $585,579; Mr. Marshall - 19 years,
current five-year covered compensation $211,817; Mr. Schwass - 18 years, current
five-year covered compensation $220,458; Ms. Green - 13 years, current five-year
covered compensation $189,484; Mr. Beck - 32 years, current five-year covered
compensation $172,805.

Employment Agreements

     DQE and Duquesne Light Company entered into a four-year employment
agreement with Mr. von Schack and three-year agreements with Mr. Marshall and
Mr. Schwass. Duquesne Light Company also entered into a three year agreement
with Ms. Green. Each agreement is subject to automatic one-year renewals unless
prior written notice of termination is given by the executive or the Company.

     The agreements provide, among other things, that each executive serve in
his or her present position at an annual base salary of at least $440,000 for
Mr. von Schack; at least $190,000 for each of Messrs. Marshall and Schwass; and
at least $165,000 for Ms. Green, subject to periodic review, and for the
participation of each in executive compensation and other employee benefit plans
of the companies.

     If any of the executives is discharged other than for cause or resigns for
good reason, then, in addition to any amounts earned but not paid as of the date
of termination, he or she would receive in a cash lump sum the balance of his or
her base salary for the remaining term of the agreement, a bonus amount of the
remaining term of the agreement calculated at a rate equivalent to his or her
prior year's bonus and the actuarial equivalent of the additional pension he or
she would have accrued had his or her service for pension purposes continued
until the expiration of the agreement.  In addition, the executive would be
entitled to immediate vesting (or the redemption in cash) of all of his or her
stock-based awards.  Mr. von Schack's agreement also provides (1) for continued
payment of base salary and bonus amounts for the remaining term of the agreement
if his employment is terminated due to death or disability and (2) for him to be
made whole for the payment of any such federal excise taxes, interest or
penalties in the event that any payments would subject him to such federal
excise tax or interest or penalties with respect to such excise tax.

     income beneficiary.

(4)  These shares are held by a Keogh trust in which Dr. Mehrabian is the sole
     trustee; he and his spouse are the beneficiaries.

(5)  The amounts shown as owned by Messrs. von Schack, Marshall and Schwass, Ms.
     Green and Mr. Beck do not include shares of DQE Common Stock which they
     have the right to acquire within 60 days of February 16, 1995 through the
     exercise of stock options granted under the Long-Term Incentive Plan in the
     following amounts:  190,805; 47,188; 58,763; 60,902; and 24,659,
     respectively, and all executive officers as a group:  382,317 shares.

(6)  The preference shares are held by the ESOP trustee for Duquesne's 401(k)
     Plan on behalf of the executive officers, who have voting but not
     investment power.  The preference shares are convertible share-for-share
     into DQE Common Stock or cash on retirement, termination of employment,
     hardship, death or disability.

Compliance with SEC Reporting Requirements

     Under Section 16(a) of the Securities Exchange Act of 1934, as amended,
Duquesne's directors, executive officers, and any persons holding more than ten
percent of the Company's Stock are required to report initial ownership of the
Company's Stock and any subsequent changes in ownership to the Securities and
Exchange Commission ("SEC").  Specific due dates have been established by the
SEC and Duquesne is required to disclose in this Statement any failure to file
by these dates.  Based upon the copies of Section 16(a) reports which Duquesne
received from such persons for their 1994 fiscal year transactions and the
written representations from such persons that no annual Form 5 reports were
required to be filed for them for the 1994 fiscal year, Duquesne believes that
there has been compliance with all Section 16(a) filing requirements except that
the initial filing of James Cross, who became an executive officer during the
year, was 13 days late.  Mr. Cross had no ownership of Duquesne Light stock at
the time of his election.

Directors' Fees and Plans

     Directors who are not officers receive an annual retainer, last set in
1990, of $15,000 payable in twelve monthly installments and a fee of $1,000 for
each Board and committee meeting attended.  Directors who are officers of the
Company receive no fees for their services as directors.

     Each director under the age of 72 who is not an officer may elect under a
directors' deferred compensation plan to defer a percentage of his or her
director's remuneration until after termination of service as a director.
Deferred compensation may be received in one to ten annual installments
commencing, with certain exceptions, on the 15th day of January of the year
designated by the participant.  Interest accrues quarterly on all deferred
compensation at a rate equal to a specified bank's prime lending rate.  Daniel
Berg, G. Christian Lantzsch and Robert Mehrabian elected to participate in the
Plan for 1994.

                                       12
<PAGE>
 
     A directors' retirement plan is in place to assure that compensation
arrangements for outside directors are adequate to attract and retain highly
qualified individuals.  Under the plan, an eligible director will receive
monthly benefits equal to the monthly retainer in effect at the time of
retirement from the Board for a period equal to the total months of service on
the DQE and Duquesne Light Boards but no longer than 120 months.  Payment of
benefits commences, unless deferred, on the first day of the month following
retirement.

     As part of its overall program to promote charitable giving, the Company
has established a directors' Charitable Giving Program funded by Company-owned
life insurance policies on the directors.  Directors are paired, and upon the
death of the second of the two directors, the Company will donate up to $500,000
each to one or more qualifying charitable organizations recommended by each of
the two directors and reviewed and approved by the Board's Employment and
Community Relations Committee.  The Company subsequently will be reimbursed by
the life insurance proceeds.  A director must have service of 60 months or more
in order to qualify for the full donation amount, with service of less than 60
months qualifying for an incremental donation.  The program does not result in
any material cost to the Company.

Compensation Committee Interlocks and Insider Participation

     The members of the Compensation Committee are Dr. Boyce and Messrs.
Bozzone, Falk and Lantzsch.  No member of the Compensation Committee was at any
time during 1994 or at any other time an officer or employee of the Company.

     No executive officer of the Company served on the Board of Directors or
Compensation Committee of any entity which has one or more executive officers
serving as a member of the Company's Board of Directors or Compensation
Committee.

CONTENTS

On the Cover
The pace of change in the electric utility industry continues to accelerate.
After decades of operating as "traditional" utilities with exclusive
franchises, the industry is entering a period of far-reaching restructuring to
meet the challenges of competition. Emerging from that restructuring will be a
new competitive paradigm--a profoundly different way in which energy companies
like DQE will operate their businesses in the competitive marketplace.


Chairman's Message                                                            2
Wesley W. von Schack discusses how DQE is strategically--and flexibly--
positioned to meet new challenges as the new competitive paradigm emerges.

Managing for the Competitive Marketplace                                      4
Anticipating and meeting the needs of the customer is fundamental to any
successful business. When your business environment is experiencing rapid
change, as is the energy industry, you must rise above the swirl to find better,
more efficient solutions for your customers. Our people are maintaining high
levels of customer satisfaction as we continue to focus internally on
performance improvement and cost control. The stories of five satisfied
customers demonstrate how we are successfully managing our company for the
competitive marketplace.

1994 Financial Information                                                    9
The company continues to effectively manage its financial position through
continued growth of its diversified operations while maintaining competitive
costs of production in its utility operations. Effective cost controls are in
place while we continue to reduce interest and other charges and maintain a
strong cash flow.

                              To Our Shareholders

Competition in the electric utility business made a lot of news during the past
year. But the reality of competition was not news to DQE shareholders. The
changing environment for utilities has been a constant theme in my letters to
shareholders for nine years. That's how long we have been preparing ourselves
for competitive markets. Our first major step in meeting marketplace demands
                         ---------------------------------------------------
came with the highly successful Duquesne Plan in 1986. The front cover of our
-----------------------------------------------------------------------------
annual report that year said: "To become more efficient, more competitive, more
--------------------------------------------------------------------------------
market-driven, more customer-oriented and more profitable, we are determined to
-------------------------------------------------------------------------------
evolve and change."
--------------------

          In 1989, we restructured our traditional business organization with
     the formation of DQE as a holding company. As we indicated at the time, our
     goal was to create a more flexible and adaptable structure, one that would
     enable us to seek opportunities and be proactive in an increasingly
     competitive environment. Since then we have continued to see remarkable
     change in our business, and the flexibility of DQE has enabled us to add
     substantial value.

          This year, the solid progress of the various businesses of DQE is
     yielding significant contributions to the overall value of the company. The
     core business represented by Duquesne Light Company is stable, while new
     business opportunities associated with Montauk and Duquesne Enterprises
     continue to grow in importance. Last year their contribution grew to more
     than 10 percent of the company's earnings, as earnings per share increased
     for the eighth consecutive year.

          The pace of change for the traditional electric utility industry is
     accelerating. Various scenarios for market forces to replace regulation are
     being discussed across the country and in our own state of Pennsylvania,
     but the public policy that will be implemented to resolve these issues is
     far from evident. As a matter of good public policy, we believe we need at
                       --------------------------------------------------------
     least two things from federal and state regulators: 1) a clear vision of
     ------------------------------------------------------------------------
     how all customers of the industry can best benefit from competition, and 2)
     ---------------------------------------------------------------------------
     a transition plan that is fair to customers and shareholders and does not
     -------------------------------------------------------------------------
     suddenly change long-established ground rules.
     ----------------------------------------------
 
          We support a regulatory vision that allows all of our retail customers
     to benefit from the lower prices that inevitably will result from vigorous
     wholesale competition. The first step toward this goal is access to the
     transmission network at non-discriminatory price and service levels. This
     cost-based service must be comparable to what transmission owners provide
     for themselves in order to ensure economically efficient investment
     decisions will be made for future generation options.

          In addition, prudent investments that were made by regulated companies
     under their clear legal obligation to provide service will have to be
     recognized as legitimate system costs. These costs should be shared by all
     electricity users, regardless of future sources of competitively priced
     power. As retail customers gain more choice in their competitive purchasing
     options, electric utility responsibilities will shift from an absolute
     obligation to service any request for power to an obligation only to
     deliver available power at competitively determined prices. Any investments
     in new generation plants, whether by utility or non-utility developers,
     would be supported by market determined prices regardless of the ultimate
     costs of these new power sources.

     this will further help us to sell energy into wholesale markets. Third, we
     also have developed innovative pricing flexibility to attract new

                   Managing For The Competitive Marketplace

Anticipating and meeting customer needs is fundamental to any successful
business. When your business environment is experiencing rapid change, as is the
energy industry, you must rise above the swirl to find better, more efficient
solutions for your customers. DQE serves diverse markets, both traditional and
emerging. In 1994, our principal subsidiary, Duquesne Light, maintained high
levels of customer satisfaction as its people continued to focus internally on
performance improvement and cost control. Our other subsidiaries proved their
worth in their markets. The following stories of five satisfied customers
demonstrate how we are successfully managing for the competitive marketplace.

"Chester Environmental's excellent work has led us to use them time and again
------------------------------------------------------------------------------
to design and engineer our wastewater treatment plants. These plants employ the
-------------------------------------------------------------------------------
latest technology and have a superb compliance record. Some are `firsts' in our
-------------------------------------------------------------------------------
industry." Peter R. Gilezan, Director, Environmental and Energy Affairs,
-------------------------------------------------------------------------
Chrysler Corporation.
---------------------

  Peter Gilezan's challenge to Chester Environmental was a major one. Chrysler
de Mexico planned to build a new Dodge Ram assembly plant in the desert
southwest of Monterrey, at Saltillo. The size of the plant and the limited
availability of water meant that Chester was asked to design and build one of
the world's largest zero-discharge water and wastewater treatment facilities.
This task was made more formidable by a six-month schedule for completion.

  Chrysler was confident Chester would be up to the challenge because it had
earned the company's preferred supplier rating five out of the six previous
years and a Quality Excellence Award given to less than 3% of Chrysler's
suppliers. That award is a key measure of demonstrated commitment to excellence
in a supplier's products and services.

  Chester delivered again at the Saltillo plant--successfully fulfilling the
largest contract in its 80-year history--by designing and overseeing
construction of a totally integrated system. The Chester solution maximizes use
of wastewater, supplemented by makeup water from a private well. Drinking and
industrial process water is chemically and biologically treated, filtered by
advanced membrane systems, and then reused in production facilities. Sanitary
wastewater similarly is recycled for irrigating the grounds around the plant.

  Chrysler is just one of a long list of Fortune 500 companies to which Chester
provides environmental engineering and scientific consulting services. Its
growing list of international clients features projects in Australia, Poland,
Taiwan and China.

  We acquired a controlling interest in Chester Environmental in 1993. Chester's
activities are closely related to our core business. Our association with
Chester is a sound investment in a growing company, and it reinforces our own
long-term commitment to the environment.

  Environmental management and control is a subject we know well. Our
environmental record and expertise are competitive advantages, especially as
other energy companies attempt to come to grips with compliance deadlines for
new environmental regulations.

  Because of Duquesne Light's pioneering efforts in pollution control
technology, the average sulfur dioxide (SO\\2\\) emission rate for our
Pennsylvania coal-burning units already is lower than the Clean Air Act requires
to meet its 1995 and 2000 standards. With more than

working toward utilizing today's extraordinary technical advances in pursuing
-----------------------------------------------------------------------------
win/win solutions, defines the parameters of a dynamic partnership. WorldClass
------------------------------------------------------------------------------
shares such a partnership with Duquesne Light."--Matthew W. Botsford, Jr., Chief
--------------------------------------------------------------------------------
Executive Officer, WorldClass Processing, Inc.
----------------------------------------------

$600 million already invested in clean air, we have relatively small capital
requirements to meet additional SO\\2\\ and nitrogen oxide standards, while
other energy providers across the country are facing much more significant
expenditures.

  Our commitment to the environment takes many forms.
 
  . A comprehensive, systematic, environmental strategic plan that addresses
compliance, training, issues management, stewardship and communications.

  . Environmental awareness training for all Duquesne Light people that connects
practically to their lives and to the more than 300 environmental regulations
that govern the company's day-to-day operations.

  . A variety of stewardship programs, including collaborative efforts with the
Western Pennsylvania Conservancy, American Forests, the Audubon Society, the
Pennsylvania Environmental Council, the National Tree Trust, Allegheny County,
and the American Legion. These and other programs educate elementary students,
high school students, Boy Scouts and Girl Scouts about the importance of
environmental preservation; foster the collection of recyclable materials;
improve land use through environmental planning and wildlife habitat
development; and help small businesses comply with new environmental
regulations. Various of these activities have received special commendations
from Allegheny County and the Pennsylvania Legislature.

  . The Three Rivers Environmental Awards, which pay tribute to individuals and
organizations in western Pennsylvania that demonstrate environmental excellence,
leadership and accomplishment. This recognition encourages others in the
community to emulate these achievements.

  With all of our customers, we strive to build the type of partnership Matt
Botsford describes. Whether helping a major customer like WorldClass Processing
to expand its operations, introducing food service providers to a new, more
efficient electrotechnology, or helping local hospitals reduce their medical
waste disposal costs through another new electrotechnology, we are committed to
helping our customers improve their competitiveness through increased use of
electricity.

  The WorldClass Processing story began in the early 1990s, when a group of
investors was seeking a location for a steel processing plant. Our economic
development team provided potential site locations and assisted in securing low-
cost state funding to finance infrastructure improvements. We also provided
competitively priced power through our special economic development rider,
designed to encourage business expansion and job creation. The plant has been a
successful processer of hot-rolled steel coils for major steel producers and
their customers.

  A decade earlier, steel manufacturing and processing represented 30% of the
record 13.6 billion kilowatt-hours (KWH) of electricity we sold to retail
customers. With the shakeout of the local steel industry, that share declined to
just 15% of the 11 billion KWH sold in 1985, an unprecedented

"It's so easy to take electrical power for granted. But if you flip the switch
-------------------------------------------------------------------------------
to start production and nothing happens, then the loss of power means more than
-------------------------------------------------------------------------------
a machine not working. It means income is lost. One of Duquesne Light's
-----------------------------------------------------------------------
strengths is its quality production of power, which helps to create world
-------------------------------------------------------------------------
competitive businesses."

drop of almost 60% in just four years. Pittsburgh in the 1990s features a more
diverse economy, based on small manufacturing, financial and medical services,
advanced technology enterprises and a world-class university system. However,
steel remains an important contributor to the local economy--13% of our 1994
sales of 12.1 billion KWH.

  In 1994, WorldClass announced plans to build the first new steel mill in this
area since World War II. The $440 million mini-mill, scheduled for construction
in four phases over the next three years, will enable WorldClass to produce a
variety of specialized steels and offer a wider range of services to larger
mills.

  The reliability of our power, and our commitment to deliver it at a
competitive price, were critical components in the WorldClass decision to
expand. We recognize that in today's economy, many of our customers face intense
competition worldwide. One of our major goals with these customers is to
structure their rates in a way that enables them to compete in global markets.

  We're also helping businesses of all sizes by providing electric options to
increase their efficiency and competitiveness. For example, we introduced local
food service providers to the benefits of the flash bake oven. This new
technology uses a combination of intense visible light and infrared energy to
cook foods almost instantly from the outside in and the inside out. Restaurants,
convenience stores, supermarkets and movie theaters now can serve a wider range
of foods better, faster and more profitably.

  New electrotechnologies also can reduce disposal costs for infectious medical
waste from hospitals and other facilities. Safely sterilizing this waste on-site
reduces the cost to bury the material in special landfills. For the past two
years, we have cosponsored educational symposiums that introduced hospital
administrators to this technology. In conjunction with a national utility
research group, we plan to open a demonstration site at a local hospital in mid-
1995.

  As chairman of one of the top ten sheet metal producers in the United States,
Milt Washington values the reliable electric service we provide. It enables SSM
Industries to use innovative technology to fabricate a wide range of products
from diverse metals.

  We take great pride in our record of reliability. In fact, independent surveys
show that we have the highest level of service reliability in Pennsylvania.

  Our commitment to reliability was tested in 1994. In January, a record-setting
freeze put electric power in short supply throughout most of the northeastern
United States and many utilities imposed rolling blackouts. In June, a heat wave
pushed customer demand to a new all-time system high--2,535 megawatts. In both
cases, we delivered safe and reliable electric energy. Pennsylvania Public
Utility Commissioner John Hanger gave Duquesne Light's January performance high
praise, saying it was "at the top of all utilities in the state."

  That performance is a result of the dedication and the skill of line workers,
customer service representatives, and the people in our System Operations and
Distribution Operations centers. The people in our

efficient customer service."

power stations play a particularly important role in providing reliable power to
both local customers, like SSM Industries, and to utility companies in other
parts of the country.

  Our available capacity is one of our key assets and an important competitive
advantage for the future. Our generating stations--the source of that power--
performed well in 1994. Beaver Valley Power Station achieved the highest
combined capacity factor--a key production measure--in the history of the
station. Cheswick Power Station achieved its highest capacity factor in 24 years
of operation.

  Reliable energy is a major consideration for companies planning an expansion
or selecting a location for a new plant. With increased computerization, more
and more customers want added protection to ensure an uninterrupted flow of
power.

  For that reason, we made a strategic investment several years ago in
International Power Machines, a world-wide supplier of power protection for
computer applications, telecommunications systems and industrial process
control. That investment will be enhanced by IPM's merger with Exide
Electronics. Exide is the largest company in the world dedicated exclusively to
developing, manufacturing and servicing a full line of power management and
power protection systems. Its customers include AT&T, IBM, the Federal Aviation
Administration and the Department of Defense.

  As both a homeowner and a regional executive director of The National
Conference of Christians and Jews, Betty Pickett appreciates not having to worry
about her electric service. She can remember only three times when her home was
without electricity during 17 years. Each outage was brief and storm-related.

  There are several good reasons why Betty never had to call us.

  . Our customers have the most reliable electric service in Pennsylvania; 99.99
percent have full power at any given time.

  . Our distribution system's remote switching devices isolate problems and
allow us to resolve most service interruptions within 15 minutes.

  . Most service interruptions requiring an "in-the-field" response are resolved
within two hours.

  Reliability is just one facet of our strong customer satisfaction record.
  
  . Customers who do need to call us (we received more than one million calls in
1994) are connected with a service representative within 13 seconds, on average.

  . Our billing accuracy is 99.95 percent. That's an average of one billing
error every seven customer lifetimes.

  . The average time required to connect a new residential service is now 24
hours.

  Independent surveys continue to prove that customers are very satisfied. They
give us particularly high ratings for reliability, courteous employees and
accurate billings.

  We are taking significant steps behind the scenes to streamline our internal
processes to further improve service and cut costs. Increased use of
microprocessors, first introduced in 1985 for meter reading, is improving
productivity in a number of functions. Expansion of the multicrafting concept
for our field workers--consolidating job descriptions and training our people
to handle a wider number of assignments--is helping

us build a more flexible and responsive workforce. A new way of scheduling
substation maintenance is reducing operating costs while maintaining
reliability.

  Our companywide focus on customer satisfaction, quality service and cost
reduction is driving continuous improvement in operations, positioning us to
be even more competitive in a changing marketplace.

  Robert Lawyer and his wife, Mary Lou, have had to make a number of adjustments
since illness forced him to retire early from his job as a machine shop
supervisor. Robert called to inquire about our award-winning Smart Comfort
program, which helps customers in need take better control of their electric
costs by developing more efficient energy-use habits.

  Traditional residential conservation programs focus on the house's outer
shell. We've turned that approach inside out. Rather than looking only at
heating, windows and insulation, we explore electric use from the customer's
perspective. How does the household use lights and appliances?

  The core of the program is an in-person analysis of the customer's monthly
bill. Working with the Lawyers, we were able to pinpoint several areas in their
trailer home where high usage could be reduced. Major improvements included
placing an insulation wrap on their electric water heater, lowering the hot-
water temperature to 120 degrees, replacing their old, inefficient refrigerator,
and replacing incandescent recessed lights in the kitchen with more efficient
compact fluorescent lamps.

  Robert thinks so highly of Smart Comfort that he's told many of his friends
about it. He even competes with a friend who has achieved similar benefits from
the program. They compare bills each month to see who has been the most
efficient.

  Smart Comfort has helped thousands of customers. The payback period for
program expenses is nearly half the industry's seven-year standard. Smart
Comfort has been recognized by the U.S. Department of Energy, the Pennsylvania
Governor's Energy Office and the Edison Electric Institute for its innovative
program design and delivery.

  Additional programs and activities to benefit the communities we serve are
logical outgrowths of Smart Comfort and other services for customers with
special needs. With service ties to the Pittsburgh area dating back nearly 115
years, we are a committed community partner.

  Education is a top priority because it will help ensure that the workforce of
the future has the skills and knowledge necessary for the 21st century. We have
particularly close ties with seven local school districts through our "Partners
in Education" program. In addition to providing cultural experiences for
children, the partnership program has been instrumental in increasing
involvement of students--particularly minorities and females--in math and
science.

  We are proud of our voluntary service to the community and we strongly
encourage our people to get involved. Last year, our people collectively
contributed almost 100,000 hours of volunteer services, helping a wide variety
of community, health, environmental and human services organizations.

Glossary of Terms
 
Following are explanations of certain financial and operating terms used in our
-------------------------------------------------------------------------------
report and unique in our core business.
---------------------------------------
 
Allowance for Funds Used During Construction (AFC)
--------------------------------------------------------------------------------
AFC is an amount recorded on the books of a utility during the period of
construction of utility assets. The amount represents the estimated cost of
both debt and equity used to finance the construction.
 
Construction Work In Progress (CWIP)
--------------------------------------------------------------------------------
This amount represents utility assets in the process of construction but not
yet placed in service. The amount is shown on the consolidated balance sheet
as a component of property, plant and equipment.
 
Deferred Energy Costs
--------------------------------------------------------------------------------
In conjunction with the Energy Cost Rate Adjustment Clause, the Company records
deferred energy costs to offset differences between actual energy costs and the
level of energy costs currently recovered from electric utility customers.
 
Demand
--------------------------------------------------------------------------------
The amount of electricity delivered to consumers at any instant or averaged
over a period of time.
 
Energy Cost Rate Adjustment Clause (ECR)
--------------------------------------------------------------------------------
The Company recovers through the ECR, to the extent that such amounts are not
included in base rates, the cost of nuclear fuel, fossil fuel and purchased
power costs and passes to its customers the profits from short-term power sales
to other utilities.
 
Equivalent Availability Factor
--------------------------------------------------------------------------------
The percent of generating capacity available for service, whether operated
or not.
 
Federal Energy Regulatory Commission (FERC)
--------------------------------------------------------------------------------
FERC is an independent five-member commission within the U.S. Department of

Management's Discussion and Analysis of
Financial Condition and Results of Operations

Corporate Structure
-------------------

DQE is an energy services holding company. Its subsidiaries are Duquesne Light
Company (Duquesne), Duquesne Enterprises (DE) and Montauk. DQE and its
subsidiaries are collectively referred to as the Company.
 
Duquesne, the principal subsidiary, is an electric utility engaged in the
production, transmission, distribution and sale of electric energy. DE is
involved in initiatives related to the core business; these include providing
all the energy services for the Pittsburgh International Airport, providing
environmental consulting and engineering services, providing power quality 
management, and investing in real estate. Montauk makes both short- and
long-term investments and raises capital for DE and for its own purposes.

Results of Operations
---------------------
 
Operating Revenues
--------------------------------------------------------------------------------
The Company sells electricity to approximately 580,000 ultimate customers
within its service territory of approximately 800 square miles in
Southwestern Pennsylvania and, on a short-term basis, to other utilities.
Customer operating revenues result from the Company's sales of electricity to
---------------------------
ultimate customers and are based on rates authorized by the Pennsylvania Public
Utility Commission (PUC). These rates are cost-based and are designed to
recover the Company's energy and other operating expenses and investment in
utility assets and to provide a return on the investment. Short-term sales to
other utilities are regulated by the Federal Energy Regulatory Commission
(FERC) and are made at market rates.

Phase-in deferred revenues represent the deferral and subsequent recovery of
--------------------------
revenues resulting from a $232 million rate increase granted in early 1988. The
PUC required the Company to phase this increase in during a six-year period,
which ended in April 1994. During this phase-in period, the rate increase was
recognized in operating revenues.

deferrals, fluctuate as a result of changes in sales volume and changes in fuel
---------
and other energy costs. Generally, the Company is permitted to recover (to the
extent that such amounts are not included in base rates) these fuel and other
energy costs from its customers through an energy cost rate adjustment clause
(ECR), subject to PUC review. This revenue adjustment includes a credit to the
Company's customers for profits from short-term sales to other utilities.
 
Revenues from sales of electricity to ultimate customers increased in 1994
compared to 1993 as a result of higher sales to commercial and industrial
customers. Commercial and industrial sales volume increased 1.3 percent and 6.9
percent, respectively, benefiting from the improving economy, as well as slight
growth in the numbers of customers. Industrial sales volume also increased as a
result of our marketing efforts and fewer customer production facility outages.
Compared to 1992, the significantly hotter summer in 1993 resulted in higher
residential and commercial sales volume. The credit to the Company's customers
for profits from short-term sales to other utilities was $16.6 million in 1994,
$12.1 million in 1993 and $19.1 million in 1992. These fluctuations primarily
resulted from changes in sales volume to other utilities.

                                       11
<PAGE>
 
The overall level of business activity in the Company's service territory and
weather conditions are expected to continue to be the primary factors affecting
sales of electricity to ultimate customers in the near term. The Company's
electric sales may also be affected in the long term by increased competition
in the electric utility industry. (See "Competition" discussion on page 16.)
 
Revenues from other utilities result from sales of electricity to other
-----------------------------
utilities. Fluctuations in electricity sales to other utilities are generally
related to the Company's customer energy requirements, the energy market and
transmission conditions and the availability of the Company's generating
stations. Because of reduced generating station availability, the Company had
fewer off-system sales in 1993 than in 1994 or 1992. Future levels of
off-system sales of electricity will be affected by the outcome of the
Company's FERC filings requesting firm transmission access. (See "Transmission
Access" discussion on page 17.)

Other operating revenues increased in 1994 and 1993 compared to the prior year 
------------------------
primarily due to growth in environmental service revenues. The increase
reflects the acquisition of a 70 percent controlling interest in Chester
Environmental, Inc. (Chester) on August 17, 1993. Chester's revenues have been
reflected in other operating revenues since that date.
             ------------------------

Operating Expenses
--------------------------------------------------------------------------------
Fuel and purchased power expense fluctuations result from changes in the cost
------------------------
of fuel, the mix between coal and nuclear generation, the total KWHs sold and
generating station availability. Because of the ECR, changes in fuel and
purchased power cost normally do not impact earnings.

Electric Utility Operating and Maintenance Expense
(Millions of Dollars)

1991     373.0

1994     358.4
</TABLE> 
Reflects ongoing cost-control efforts. (Excludes one-time lease termination
charge in 1993.)
 
The average unit cost of coal declined slightly in 1994, after remaining
relatively constant during 1993. Meanwhile, the average unit cost of nuclear
fuel has declined continually during the past three years.
 
Generation mix impacts fuel expense as the Company's nuclear fuel cost per KWH
is less than its fossil fuel cost per KWH. During 1993, compared to 1994 and
1992, the Company had more scheduled nuclear station refueling outages,
resulting in less nuclear generation and more fuel expense.
 
Generation volume during 1994 increased 3.4 percent compared to 1993 due to
fewer generating station outages. During 1993, generation decreased 5.6 percent
from 1992.
 
Purchased power volume increased in 1994 compared to 1993 because of the timing
of generating station outages. Purchased power volume increased in 1993 compared
to 1992 primarily due to the performance of the Perry plant. (See "Perry Unit 1"
discussion on page 15.)
 
Other operating expenses decreased slightly in 1994 compared to 1993 despite a
---------------
$25.0 million increase in operating expenses at Chester, the result of a full
year's ownership in 1994. This increase was offset by the continuation of the
Company's cost reduction program and by the 1993 recording of a $15.2 million
long-term power sale write-off and a $12.8 million property subleasing charge.
These 1993 charges, along with the Chester acquisition, accounted for the
increase in 1993 compared to 1992.

Maintenance expense fluctuations primarily result from the timing of scheduled
-----------
generating station outages, the timing of scheduled transmission and
distribution line maintenance and the effect of storms on overhead lines and
transformers. Incremental maintenance expense

                                       12
<PAGE>
 
incurred for scheduled refueling outages at the Company's nuclear units is
deferred for amortization over the period (generally 18 months) between
scheduled outages. During 1994 and 1993, amortization of deferred nuclear
refueling outage expense increased, reflecting the higher costs of more recent
refueling outages. Offsetting this increase in 1994 was a decrease in
transmission and distribution line maintenance expense. Also increasing
maintenance expense in 1993 was the Company's change, as of January 1, 1993, in
-----------
its method of accounting for maintenance costs during major fossil generating
station outages. Prior to 1993, maintenance costs incurred for scheduled major
outages at fossil generating stations were charged to expense as the costs were
incurred. Under the new accounting policy, the Company accrues, over the period
between outages, anticipated expenses for scheduled major fossil station
outages. (Maintenance costs incurred for non-major scheduled outages and for
forced outages continue to be charged to expense as the costs are incurred.)
This method was adopted to match more accurately the maintenance costs with the 
revenue produced during the periods between scheduled major fossil generating
station outages.
 
Depreciation and amortization expense includes, in addition to depreciation of
-----------------------------
plant and equipment, nuclear decommissioning accruals, amortization of
regulatory tax receivables and amortization of an extraordinary property loss.
Depreciation and amortization expense increased in 1994 and 1993 compared to the
-----------------------------
prior year due to increases in depreciable property, nuclear decommissioning
expense and leveraged lease amortization. The 1993 increase also results from
amortization of regulatory tax receivables which began January 1, 1993,
concurrent with the adoption of Statement of Financial Accounting Standards No.
                                -----------------------------------------------
109 (SFAS No. 109). During 1994, the Company completed an extensive review of
------------------
its depreciation rates and submitted an informational filing to the PUC. As a
result of this study, beginning in 1995 the Company's composite depreciation
rate increased from 3.0 percent to 3.5 percent. It is anticipated that annual
depreciation expense will increase by approximately $25 million in 1995 compared
to the 1994 level. The Company is not currently seeking a rate increase to cover
these additional costs.
 
Taxes other than income taxes were lower in 1993 compared to 1994 and 1992,
-----------------------------
primarily as a result of a favorable resolution of certain property tax
assessments. In 1993, the Company recorded, on the basis of these revised
assessments, the expected refunds for overpayments in prior years.

first mortgage bonds and certain tax exempt pollution control notes and through
retiring debt. Interest expense is expected to decline further in 1995.
               ----------------
 
Preferred and preference dividends of subsidiaries continue to decrease as a
--------------------------------------------------
result of the retirement of several outstanding issues. During 1994, the Company
retired $39.9 million of preferred and preference stock.
 
Income Taxes
--------------------------------------------------------------------------------
Income tax expense was lower in 1993, compared to 1994 and 1992, because of a
----------
favorable settlement (related to Duquesne's 1988 federal income tax return and
the Company's 1989 consolidated federal income tax return) with the Internal
Revenue Service. The remaining fluctuations result from a 1 percent increase in
the corporate federal income tax rate in 1993 and changes in taxable income.
During 1994 the statutory Pennsylvania income tax rate was reduced from 12.25
percent to 9.99 percent; this reduction is to be phased in over four years. This
change resulted in a net decrease of $87.2 million in deferred tax liabilities 
and a corresponding reduction in the regulatory receivable.

Capital Expenditures and Investing
-------------------------------------------------------------------------------
During 1994, the Company spent approximately $94.3 million for utility
construction. The Company spent approximately $100.6 million in 1993 and
$112.4 million in 1992 for utility construction. These amounts were expended to
improve and/or expand its production, transmission and distribution systems. 
Utility construction programs of the Company focus on the need to serve new 
customers, to provide for the replacement of utility property and to modify 
facilities consistent with the most current environmental and safety 
regulations. The Company estimates that it will spend approximately $80 million
for utility construction annually in 1995, 1996 and 1997. These amounts exclude
AFC, nuclear fuel, expenditures for possible early replacement of steam
generators at the Beaver Valley Power Station and expenditures for the
refurbishment of the cold-reserved units. (See Notes F and J to the
consolidated financial statements.) The Company currently has no plans for
construction of new base load generating plants. The Company expects that funds
generated from operations will continue to be sufficient to finance a large part
of its capital needs.
 
In addition to utility construction, the Company's long-term investments are
focused in four principal areas: real estate investments, energy-related
investments, leasing investments and environmental services investments. The
level of investing activities stayed relatively constant in 1994 after
increasing in 1993 compared to 1992. Lease investments in 1994 were $52.3
million, of which $18.8 million were energy-related. Real estate investments in
1994 were $48.9 million, including $22.1 million in affordable housing, and, on
a net basis, other investments decreased $7.7 million. In 1993, the Company
invested $59.1 million in real estate, including $35.4 million in affordable
housing, and $24.7 million in leasing and other investments. Also during 1993,
the Company acquired a controlling interest in Chester for $11.9 million. The
Company's 1992 investments were primarily in energy-related leases.
 
Financing
-------------------------------------------------------------------------------
The Company plans to meet its current obligations and debt maturities through
1999 with funds generated from operations and through new financings. At
December 31, 1994, the Company was in compliance with all of its debt covenants.
 
During 1993, the Company refinanced $734.2 million of long-term debt. In 1994,
the Company continued to reduce its cost of capital by refinancing and retiring
securities.
 
During 1994, all of the outstanding shares of $2.10 and $7.50 preference stock
were redeemed for approximately $37.7 million. The Company also retired $2.2
million of $7.20 preferred stock. In May 1994, the Company filed a shelf
registration statement for the issuance of up to $150 million of Duquesne
Capital L.P. Cumulative Monthly Income Preferred Securities. These preferred
securities have not been issued.
 
During 1994, the Company also issued $114.1 million of its pollution control
obligations to replace a like amount of higher cost pollution control
obligations. The new pollution control obligations bear variable interest rates
and mature October 1, 2029.
 
The Company maintains two extendible revolving credit agreements, including a
$100 million arrangement expiring August 1995, and a $150 million arrangement
expiring October, 1995. Both arrangements contain two-year repayment periods for
any amounts outstanding at the expiration of the revolving credit periods. At
December 31, 1994, the Company had borrowed $60 million under the agreements.

Sale of Accounts Receivable
-------------------------------------------------------------------------------
The Company and an unaffiliated corporation have an agreement that entitles the
Company to sell and the corporation to purchase, on an ongoing basis, up to $50
million of accounts receivable. The Company had no receivables sold at
December 31, 1994. The accounts receivable sales agreement, which expires in
June 1995, is one of many sources of funds available to the Company. Upon
expiration of this facility, the Company expects to extend the agreement or to
replace the facility with a similar one.

Nuclear Fuel Leasing
-------------------------------------------------------------------------------
The Company finances its acquisitions of nuclear fuel through a leasing
arrangement under which it may finance up to $75 million of nuclear fuel. As of
December 31, 1994, the amount of nuclear fuel financed by the Company under
this arrangement totaled approximately $52 million. The Company plans to
continue leasing nuclear fuel to fulfill its requirements at least through
September 1996, the remaining term of the current leasing arrangement.
 
Dividends
-------------------------------------------------------------------------------
The Company has paid dividends on common stock continuously since 1953. The
quarterly dividends paid have increased by an average annual rate of 5.6 percent
over the past five years, even though the Company has maintained a more
conservative payout ratio than the electric utility industry in general. The
Company expects that funds generated from operations will continue to be
sufficient to meet sinking fund and long-term debt maturities and to pay
dividends. The Company's need and the availability of funds will be influenced
by the economic activity within the Company's utility service territory, by
competitive and environmental legislation and by regulatory matters experienced
by the electric utility industry generally.
 
Dividends may be paid on DQE common stock to the extent permitted by law and as
declared by the board of directors. However, in Duquesne's Restated Articles of
                                                           -----------------
incorporation, provisions relating to preferred and preference stock may
restrict the payment of Duquesne's common dividends. No dividends or
distributions may be made on Duquesne's common stock if Duquesne has not paid
dividends or sinking fund obligations on its preferred or preference stock.
Further, the aggregate amount of Duquesne's common stock dividend payments or
distributions may not exceed certain percentages of net income if the ratio of
common shareholders' equity to total capitalization is less than specified
percentages. As all of Duquesne's common stock is owned by DQE, to the extent
that Duquesne cannot pay common dividends, DQE may not be able to pay dividends
to its common shareholders. No part of the retained earnings of DQE or any of
its subsidiaries was restricted at December 31, 1994.
 
Generating Units
----------------

Generating Performance
-------------------------------------------------------------------------------
The Company wholly owns and operates two generating units. In addition, the
Company has an ownership or leasehold interest in nine jointly owned units, two
of which the Company operates. Of the four units the Company operates, three
achieved record performance during 1994.
 
The Beaver Valley Power Station achieved the highest combined (Units 1 and 2)
capacity factor (87.7 percent) in the history of the station. The Cheswick Power
Station achieved the highest capacity factor (78.7 percent) in its 24-year
history. Capacity factor is a key production measure. It is the ratio of the
power actually generated by a facility to the facility's rated capacity during
that period of time. It is also a key indicator of how well the stations are
operated based on their design capabilities.
 
Perry Unit 1
-------------------------------------------------------------------------------
The Company has a 13.74 percent ownership interest in Perry Unit 1, a nuclear
generating unit located in Ohio and operated by The Cleveland Electric 
Illuminating Company (CEI). During 1993, the unit had an equivalent
availability factor of 39 percent. This performance resulted from several
outages. As a result of the length of these outages, the PUC imposed a penalty
for incremental replacement power costs. The 1994 equivalent availability factor
was 44 percent. This performance resulted from an extended outage (190 days)
for refueling and

                                       15
<PAGE>
 
maintenance. From the end of the outage in August 1994 thorugh the balance of 
1994, Perry operated at full capacity except for short durations of reduced 
power for testing and minor on-line maintenance activities.
 
CEI has prevoiusly submitted to the Nuclear Regulatory Commission an action
plan, called the Perry Course of Action (PCA), designed by CEI to "correct
identified management, technical, and programmatic deficiencies" at the plant
over roughly a three-year period, and to "correct the downward trending
performance" of Perry. CEI management represents to us that the PCA is on
schedule and will be an effective program to insure that Perry is in conformance
with industry standards for boiling water reactors. Based on actual costs and 
estimates obtained from CEI through January 1995, the total costs to bring the 
plant into compliance, including the costs associated with implementing the PCA,
are more than the costs originally projected by CEI. The Company cannot predict 
the ultimate cost, timing or effectiveness of the PCA, and is continuing to 
closely monitor the situation.

Outlook
-------
 
Competition
-------------------------------------------------------------------------------
Regulatory developments in the electric utility industry are placing increasing 
competitive pressures on electric utilities. The electric utility industry is
expected to continue to undergo significant changes for the remainder of the
decade. These changes most likely will include increasing competition in the
generation and sale of electricity, increasing energy flows resulting from open
transmission access and non-regulated generation and transmission projects
outside the traditional service areas. The Company, like the industry in
general, is continuing to assess the impact of these competitive forces on its
future operations.
 
Electric Utility Industry Developments: The National Energy Policy Act of 1992
--------------------------------------  --------------------------------------
(energy act) was designed, among other things, to foster competition. Among
other provisions, the energy act amends the Public Utility Holding Company Act
                                            ----------------------------------
of 1935 (1935 act) and the Federal Power Act. Amendments to the 1935 act create
-------                    -----------------
a new class of independent power producers known as Exempt Wholesale Generators
(EWGs), which are exempt from the corporate structure regulations of the 1935
act. EWGs, which may include independent power producers as well as affiliates
of electric utilities, do not require Securities and Exchange Commission
approval or regulation. In addition, brokers and marketers, without owning or
operating any generation or transmission facilities, are being permitted to
enter into the business of buying and selling electric capacity and energy.
 
Amendments to the Federal Power Act create the potential for utilities and other
                  -----------------
power producers to gain increased access to transmission systems of other
utilities in order to facilitate sales to other utilities. The amendments permit
the FERC to order utilities to transmit power over their lines for use by other
suppliers and to enlarge or construct additional transmission capacity to
provide these services. The Company is currently pursuing expanded transmission
access under these amendments. (See discussion in "Transmission Access" on page
17.)
 
The energy efficiency title of the energy act requires states to consider
adopting integrated resource planning, which allows utility investments in
conservation and other demand side management techniques to be at least as
profitable as supply investments. The energy act also establishes new efficiency
standards in industrial and commercial equipment and lighting and requires
states to establish commercial and residential building codes with energy
efficiency standards. Additionally, the energy act requires utilities to
consider energy efficiency programs in their integrated resource planning.
 
These new regulations also permit industrial and large commercial customers to
own and operate facilities to generate their own electric energy requirements
and, if such facilities are qualifying facilities, to require the displaced
electric utility to purchase the output of such facilities. Customers may also
have the option of substituting fuels, such as the use of natural gas, oil or
wood for heating and/or cooling purposes rather than electric energy or of
relocating their facilities to a lower cost environment.

                                       16
<PAGE>
 
The PUC is currently conducting an investigation into electric power
competition. The Company has been advocating increased transmission access in
the wholesale power market as the necessary first step toward enabling our 
customers to benefit from competition.
 
The Company's Response: Emerging competition, federal deregulation of wholesale
----------------------
energy sales, and prospective retail access initiatives require the Company to
reexamine its approach to doing business. Growth in energy sales, competitive
rate pressures, and the Company's commitment to provide reliable, quality
service to its customers influence short- and long-term corporate goals. The
Company's current business plan recognizes the need to encourage economic
growth and stability in the service territory and surrounding region. The
Company's efforts continue to focus on achievement of business growth through
the application of marketing and economic development programs to achieve
energy-efficient growth in its sales of utility services.
 
The Company has a diverse customer mix with less than 22 percent of total sales
of electricity derived from industrial customers as compared to an electric
utility industry average of approximately 34 percent. The Company's rates for 
energy intensive industrial and commercial customers are competitively priced
and its rate structure allows some flexibility in setting rates to attract new 
business. In addition, Company-sponsored programs help customers manage their
electricity consumption and control their costs.
 
Although management believes the Company's system is well positioned, as a
clean, low cost producer, to compete both within and outside of its service
territory, efforts continue to further reduce costs and increase effectiveness
and productivity. We will aggressively address these factors to position the
Company to overcome the challenges they may create and take advantage of the
opportunities increased competition will bring.
 
Transmission Access: In March 1994, the Company submitted, pursuant to the
-------------------
Federal Power Act, a "good faith" request for transmission service with the
-----------------
Allegheny Power System (APS) and Pennsylvania-New Jersey-Maryland
Interconnection Association (PJM Companies). The request is based on 20-year
firm service with flexible delivery points for 300 megawatts of transfer
capability over the transmission network that extends from Western Pennsylvania
to the East Coast. Because of a lack of progress on pricing and other issues, on
August 5 and September 16, 1994, the Company filed with the FERC applications
for transmission service from the PJM Companies and APS, respectively. The
applications are authorized under Section 211 of the Federal Power Act, which
                                                     -----------------
requires electric utilities to provide firm wholesale transmission service.
 
Generating Units Held for Future Use: In 1986, the PUC approved the Company's
------------------------------------
request to remove the Phillips and most of the Brunot Island (BI) power stations
from service and place them in cold reserve. The Company expects to recover its
net investment in these plants through future electricity sales. Phillips and BI
represent licensed, certified, clean sources of electricity that will be
necessary to meet expanding opportunities in the power markets. The Company
believes that anticipated growth in peak demand for electricity within its
service territory will require additional peaking generation. The Company looks
to BI to meet this need. The Phillips power plant is an important component in
the Company's strategy to identify and serve opportunities for providing bulk
power service. With recent legislation promoting wider transmission access to
bulk power markets and with the opportunity to package a sale of power from
Phillips with the support of the Company's system, the Phillips plant could be
made a highly reliable, cost-competitive alternative for most purchasers. In
summary, the Company believes its investment in these cold-reserved plants will
be necessary in order to meet future business needs. If business opportunities
do not develop as expected, the Company will consider the sale of these assets.
In the event that market demand, transmission access or rate recovery do not
support the utilization or sale of the plants, the Company may have to write off
part or all of their costs. At December 31, 1994, the Company's net investment 
in Phillips and BI was $93.0 million and $42.0 million, respectively.

Environmental Matters
--------------------------------------------------------------------------------
The Comprehensive Environmental Response, Compensation and Liability Act of 1980
--------------------------------------------------------------------------------
(Superfund) and the Superfund Amendments and Reauthorization Act of 1986
                    ----------------------------------------------------
established a variety of informational and environmental action programs. The
United States Environmental Protection Agency (EPA) has informed the Company of
its involvement or potential involvement in three hazardous waste sites. If the
Company is ultimately determined to be a responsible party with respect to these
sites, it could be liable for all or a portion of the cleanup costs. However, in
each case, other solvent, potentially responsible parties that may bear all or
part of any liability are also involved. In addition, the Company believes that
available defenses, along with other factors (including overall limited
involvement and low estimated remediation costs for one site) will limit any
potential liability that the Company may have for cleanup costs. The Company
believes that it is adequately reserved for all known liabilities and costs and,
accordingly, that these matters will not have a materially adverse effect on its
financial position or results of operations.
 
In 1990, Congress approved amendments to the Clean Air Act. Among other
                                             -------------
innovations, this legislation established the Emission Allowance Trading System.
These allowances are issued by the EPA to fossil-fired stations with generating
capability of more than 25 megawatts that were in existence as of the passage of
the 1990 amendments. Allowances are part of a market-based approach to sulfur
dioxide (SO//2//) reduction. Emission allowances can also be obtained through
purchases on the open market or directly from other sources. Excess allowances
may be banked for future use or sold on the open market to other parties for
their use in offsetting emissions.
 
The legislation requires significant additional reductions of SO//2// and oxides
of nitrogen (NO//X//) by the year 2000. The Company continues to work with the
operators of its jointly owned stations to implement cost-effective compliance
strategies to meet these requirements. NO//X// reductions under Title IV of the
Clean Air Act amendments were required at the Cheswick station and the work to
-------------
achieve the reductions was completed in 1993. The ozone attainment provisions
of Title I of the Clean Air Act amendments also required NO//X// reductions by
   ----------------------------
1995 at the Company's Elrama plant and at the jointly owned Mansfield plant. The
Company will achieve such reductions with low NO//X// burner technology. The

Company has 662 megawatts of nuclear capacity, 1,187 megawatts of scrubbed
capacity, including 300 megawatts at the currently cold-reserved Phillips plant,
and 757 megawatts of capacity that meets the 1995 standards of the Clean Air Act
                                                                   -------------
amendments through the use of low sulfur coal. Through the year
2000, the Company is planning a combination of compliance methods that include
fuel switching; increased use of, and improvements in, scrubbed capacity; flue
gas conditioning; low NO//X// burner technology; and the purchase of emission
allowances. The Company currently estimates that additional capital costs to
comply with Clean Air Act requirements through the year 2000 will be
            -------------
approximately $20 million. This estimate is subject to the finalization of
federal and state regulations.
 
The Company is closely monitoring other potential air quality programs and air
emission control requirements that could be imposed in the future, including
additional NO//X// control requirements that could be imposed on fossil fuel
plants by the Ozone Transport Commission. As these potential programs are in
various stages of discussion and consideration, it is impossible to make
reasonable estimates of the potential costs and impacts, if any.
 
In 1992, the Pennsylvania Department of Environmental Resources (DER) issued
Residual Waste Management Regulations governing the generation and management of
non-hazardous waste. The Company is currently conducting tests and developing
compliance strategies. Capital compliance costs for these DER regulations are
estimated, on the basis of information currently available, at $5 million in
1995. The expected additional capital cost of compliance for these DER
regulations through 2000 is estimated, based on current information, to be
approximately $25 million; this estimate is subject to the results of continuing
ground water assessments and DER final approval of compliance plans.

Under the Nuclear Waste Policy Act of 1982, which establishes a policy for
          --------------------------------
handling and disposing of spent nuclear fuel and requires the establishment of a
final repository to accept spent fuel, contracts for jointly owned nuclear
plants have been entered into with the United States Department of Energy (DOE)
for permanent disposal of spent nuclear fuel and high-level radioactive waste.
The DOE has indicated that the repository will not be available for acceptance
of spent fuel before 2010. Existing on-site spent fuel storage capacities at
Beaver Valley Unit 1, Beaver Valley Unit 2 and Perry are expected to be
sufficient until 2017, 2011, and 2009, respectively. During 1994, the Company
increased the storage capacity at Beaver Valley Unit 1 by equipping the spent
fuel pool with high density fuel storage racks.
 
Retirement Plan Measurement Assumptions
--------------------------------------------------------------------------------
The Company increased the discount rate used to determine the projected benefit
obligation on the Company's retirement plans at December 31, 1994, to 8.0
percent. The assumed change in future compensation levels was also increased to
reflect current market and economic conditions.
 
The effects of these changes on the Company's retirement plan obligations are
reflected in the amounts shown in Note N to the consolidated financial
statements. The resulting decrease in related expenses for subsequent years is
not expected to be material.
 
Investment in International Power Machines Corporation (IPM)
--------------------------------------------------------------------------------
The Company had a $2.8 million investment, reflected in the Consolidated Balance
Sheet of DQE as Other Long-Term Investments at December 31, 1994, in IPM
                ---------------------------
convertible preferred stock. On February 8, 1995, IPM was acquired by Exide
Electronics Group, Inc. (Exide). The Company is now a major shareholder of
Exide, the world's largest independent developer, manufacturer and servicer of
power protection and power management systems. This acquisition resulted in a
first quarter 1995 pre-tax gain for the Company of approximately $7.2 million,
or eight cents per share.
 
Other
--------------------------------------------------------------------------------
The Company is subject to the accounting and reporting requirements of the 
Securities and Exchange Commission. In addition, the Company's utility 
operations are subject to the regulation of the PUC and the FERC. As a result, 
the consolidated financial statements contain regulatory assets and liabilities 
in accordance with Statement of Financial Accounting Standards No. 71, 
                   ---------------------------------------------------
Accounting For the Effects of Certain Types of Regulation (SFAS No. 71) and 
-----------------------------------------------------------------------
reflect the effects of the ratemaking process. In accordance with SFAS No. 71, 
                                                                  ------------
the Company's financial statements reflect regulatory assets and costs based on 
current cost-based ratemaking regulations. The regulatory assets represent 
probable future revenue to the Company because provisions for these costs are 
currently included, or are expected to be included, in charges to utility 
customers through the ratemaking process.

The Company's electric utility operations currently satisfy the criteria of 
SFAS No. 71. However, a company's utility operations or a portion of such 
-----------
operations can cease to meet these criteria for various reasons including a 
change in regulation. Should the Company cease to meet the SFAS No. 71 criteria,
                                                           -----------
it would be required to write-off any regulatory assets and liabilities for 
those operations that no longer meet these requirements.

Report of Independent Certified Public Accountants
--------------------------------------------------
 
To the Directors and Shareholders of DQE:
----------------------------------------
 
We have audited the accompanying consolidated balance sheets of DQE and its
subsidiaries as of December 31, 1994 and 1993, and the related consolidated
statements of income, retained earnings, and cash flows for each of the three
years in the period ended December 31, 1994. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements 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, such consolidated financial statements present fairly, in all
material respects, the financial position of DQE and its subsidiaries as of
December 31, 1994 and 1993, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 1994 in
conformity with generally accepted accounting principles.
 
As discussed in Note A to the consolidated financial statements, effective
January 1, 1993, the Company changed its method of accounting for income taxes
to conform with Statement of Financial Accounting Standards No. 109, and the
Company changed its method of accounting for maintenance costs during scheduled
major fossil station outages.

Report of the Audit Committee of the Board of Directors of DQE
--------------------------------------------------------------
 
The Audit Committee, composed entirely of non-employee directors, meets
regularly with the independent public accountants and the internal auditors to
discuss results of their audit work, their evaluation of the adequacy of the
internal accounting controls and the quality of financial reporting.
 
In fulfilling its responsibilities in 1994, the Audit Committee recommended to
the Board of Directors, subject to shareholder approval, the selection of the
Company's independent public accountants. The Audit Committee reviewed the
overall scope and details of the independent public accountants' and internal
auditors' respective audit plans and reviewed and approved the independent
public accountants' general audit fees and non-audit services.
 
Audit Committee meetings are designed to facilitate open communications with
internal auditors and independent public accountants. To ensure auditor
independence, both the independent public accountants and the internal auditors
have full and free access to the Audit Committee.

Notes to Consolidated Financial Statements

A. Summary of Significant
   Accounting
   Policies

Consolidation
------------------------------------------------------------------------------
The consolidated financial statements of DQE include the accounts of its
subsidiaries: Duquesne Light Company (Duquesne), Duquesne Enterprises (DE) and
Montauk. DQE and its subsidiaries are collectively referred to as the Company.
All material intercompany balances and transactions have been eliminated in the
preparation of the Consolidated Financial Statements of DQE.

On August 17, 1993, DE acquired a 70 percent controlling interest in Chester
Environmental, Inc. (Chester) for approximately $12 million. The acquisition was
accounted for under the purchase method of accounting and Chester's results of
operations have been included in the Company's consolidated financial statements
since that date.

Basis of Accounting
------------------------------------------------------------------------------
The Company is subject to the accounting and reporting requirements of the
Securities and Exchange Commission (SEC). In addition, the Company's utility
operations are subject to the regulation of the Pennsylvania Public Utility
Commission (PUC) and the Federal Energy Regulatory Commission (FERC). As a
result, the consolidated financial statements contain regulatory assets and
liabilities in accordance with Statement of Financial Accounting Standards No.
                               -----------------------------------------------
71, Accounting for the Effects of Certain Types of Regulation (SFAS No. 71) and
--
reflect the effects of the ratemaking process. Such effects concern mainly the
time at which various items enter into the determination of net income in
accordance with the principle of matching costs and revenues. (See Note F.)

Revenues
------------------------------------------------------------------------------
Meters are read monthly and customers are billed on the same basis. Revenues
are recorded in the accounting periods for which they are billed, with the
exception of energy cost recovery revenues. (See following section on ``Energy
Cost Rate Adjustment Clause.'') Deferred revenues are associated with the
Company's 1987 rate case. (See Note F.)

Energy Cost Rate Adjustment Clause (ECR)
------------------------------------------------------------------------------
Through the ECR, the Company recovers (to the extent that such amounts are
not included in base rates) nuclear fuel, fossil fuel and purchased power
expenses and, also through the ECR, passes to its customers the profits from
short-term power sales to other utilities (collectively, ECR energy costs).
Nuclear fuel expense is recorded on the basis of the quantity of electric
energy generated and includes such costs as the fee, imposed by the United
States Department of Energy (DOE), for future disposal and ultimate storage and
disposition of spent nuclear fuel. Fossil fuel expense includes the costs of
coal, natural gas and fuel oil used in the generation of electricity.

On the Company's statement of consolidated income, these energy cost
recovery revenues are included as a component of operating revenues. For ECR
purposes, the Company defers fuel and other energy expenses for recovery, or
refunding, in subsequent years. The deferrals reflect the difference between
the amount that the Company is currently collecting from customers and its
actual ECR energy costs. The PUC annually reviews the Company's ECR energy
costs for the fiscal year April through March, compares them to previously
projected ECR energy costs and adjusts the ECR for over- or under-recoveries
and for two PUC-established coal cost standards. (See Note F.)

                                       25
<PAGE>
 
Over or under-recoveries from customers are recorded in the Consolidated
Balance Sheet of DQE as payable to, or receivable from, customers. At December
31, 1994, $5.9 million was receivable from customers and shown as other current
assets. At December 31, 1993, $10.1 million was payable to customers and shown
as other current liabilities.

Maintenance
------------------------------------------------------------------------------
Incremental maintenance expense incurred for refueling outages at the Company's
nuclear units is deferred for amortization over the period (generally eighteen
months) between scheduled outages. The Company changed, as of January 1, 1993,
its method of accounting for maintenance costs during scheduled major fossil
generating station outages. Prior to that time, maintenance costs incurred for
scheduled major outages at fossil generating stations were charged to expense as
these costs were incurred. Under the new accounting policy, the Company accrues,
over the periods between outages, anticipated expenses for scheduled major
fossil generating station outages. (Maintenance costs incurred for non-major
scheduled outages and for forced outages continue to be charged to expense as
such costs are incurred.) This method was adopted to match more accurately the
maintenance costs and the revenue produced during the periods between scheduled
major fossil generating station outages.

The cumulative effect (approximately $5.4 million, net of income taxes of
approximately $3.9 million) of the change on prior years was included in net
income in 1993. The effect of the change in 1993 was to reduce income, before
the cumulative effect of changes in accounting principles, by approximately $2.4
million or $.05 per share and to reduce net income, after the cumulative effect
of changes in accounting principles, by approximately $7.8 million or $.15 per
share. The effect of the scheduled major fossil station outage accrual in 1994
was to reduce net income by approximately $0.7 million, or $.01 per share.

Depreciation and Amortization
------------------------------------------------------------------------------
Depreciation of property, plant and equipment, including plant-related
intangibles, is recorded on a straight-line basis over the estimated useful
lives of properties. Amortization of other intangibles is recorded on a straight
line basis over a five-year period. Depreciation and amortization of other
properties are calculated on various bases.

The Company records decommissioning costs under the category of depreciation and
amortization expense and accrues a liability, equal to that amount, for nuclear
decommissioning expense. Such nuclear decommissioning funds are deposited in
external, segregated trust accounts. The funds are invested in a portfolio
consisting of municipal bonds, certificates of deposit, and U.S. government
securities. Trust fund earnings increase the fund balance and the recorded
liability. The market value of the aggregate trust fund balances at December 31,
1994 totaled $19.2 million. On the Company's consolidated balance sheet, the
decommissioning trusts have been reflected in long-term investments, and the
related liability has been recorded as other liabilities.

Income Taxes
------------------------------------------------------------------------------
On January 1, 1993, the Company adopted Statement of Financial Accounting
Standards No. 109, Accounting for Income Taxes (SFAS No. 109). Implementation of
SFAS No. 109 involved a change in accounting principle. The cumulative $8
million effect on prior years was reported in 1993 as an increase in net income.

SFAS No. 109 requires that the liability method be used in computing deferred
taxes on all differences between book and tax bases of assets. These book tax
differences occur when events and transactions recognized for financial
reporting purposes are not recognized in the same period for tax purposes. SFAS
No. 109 also requires that a deferred tax liability or asset be adjusted in the
period of enactment for the effect of changes in tax laws or rates. During 1994
the statutory Pennsylvania income tax rate was reduced from 12.25 percent to
9.99 percent; this reduction is to be phased in over four years. This resulted
in a net decrease of $87.2 million for deferred tax liabilities.

For its utility operations, the Company recognizes a regulatory asset for the
deferred tax liabilities that are expected to be recovered from customers
through rates. (See Notes F and H).

                                       26
<PAGE>
 
With respect to the financial statement presentation of SFAS No. 109, the
Company reflects the amortization of the regulatory tax receivable resulting
from reversals of deferred taxes as depreciation and amortization expense.
Changes in the regulatory tax receivable as a result of a change in tax rates
are reflected in the statement of consolidated income on the tax rate
adjustment_regulatory tax receivable line. Reversals of accumulated deferred
income taxes are included in income tax expense.

When applied to reduce the Company's income tax liability, investment tax
credits related to utility property generally were deferred. Such credits are
subsequently reflected, over the lives of the related assets, as reductions to
tax expense.

Property, Plant and Equipment
------------------------------------------------------------------------------
The asset values of the Company's utility properties are stated at original
construction cost, which includes related payroll taxes, pensions, and other
fringe benefits, as well as administrative and general costs. Also included in
original construction cost is an allowance for funds used during construction
(AFC), which represents the estimated cost of debt and equity funds used to
finance construction. The amount of AFC that is capitalized will vary according
to changes in the cost of capital and in the level of construction work in
progress (CWIP). On a current basis, the Company does not realize cash from the
allowance for funds used during construction. The Company does realize cash,
during the service life of the plant, through increased revenues reflecting a
higher rate base (upon which a return is earned) and increased depreciation.
The AFC rates applied to CWIP were 9.0 percent in 1994, 9.6 percent in 1993,
and 10.3 percent in 1992.

Additions to, and replacements of, property units are charged to plant
accounts. Maintenance, repairs and replacement of minor items of property are
recorded as expenses when they are incurred. The costs of utility properties
that are retired (plus removal costs and less any salvage value) are charged to
the accumulated provision for depreciation.

Substantially all of the Company's utility properties are subject to first
mortgage liens, and to junior liens.

Temporary Cash Investments
------------------------------------------------------------------------------
Temporary cash investments are short-term, highly liquid investments with
original maturities of three or fewer months. They are stated at market, which
approximates cost. The Company considers temporary cash investments to be cash
equivalents.

Reclassifications
------------------------------------------------------------------------------
The 1993 and 1992 financial statements have been reclassified to conform with
accounting presentations adopted during 1994.

B. Receivables

An arrangement between the Company and an unaffiliated corporation entitles the
Company to periodically sell up to $50 million of its accounts receivable. The
Company sold receivables from time to time throughout 1994 but had no
receivables sold at December 31, 1994. At December 31, 1993, the Company had
sold $7.1 million of electric customer accounts receivable and $1.9 million of
other utility receivables. The sales agreement includes a limited recourse
obligation under which the Company could be required to repurchase certain of
the receivables. The arrangement expires on June 27, 1995.

D. Long-Term
   Investments

The Company's partnership investments are primarily in affordable housing
limited partnerships. The Company's investments in affordable housing were $57.5
million at December 31, 1994 and $35.4 million at December 31, 1993. The Company
also has a partnership investment at December 31, 1994 of $15.7 million in a
waste-to-energy facility.

The Company is the lessor in five leveraged lease arrangements involving
manufacturing equipment, mining equipment, rail equipment and natural gas
processing equipment. These leases expire in various years beginning 2001
through 2012. The residual value of the equipment, which belongs to the Company
after the leases expire, is estimated to approximate 14 percent of the original
cost. The Company's aggregate equity investment represents 22 percent of the
aggregate original cost of the property and is secured by guarantees of each
lessee's parent or affiliate. The remaining 78 percent was financed by non-
recourse debt provided by lenders who have been granted, as their sole remedy in
the event of default by the lessees, an assignment of rentals due under the
leases and a security interest in the leased property. This debt amounted to
$139 million and $144 million at December 31, 1994 and 1993, respectively.

</TABLE>

The Company's leasehold investments are in computers, vehicles and equipment.
The Company's other investments are primarily in assets of a nuclear
decommissioning trust and marketable securities. In accordance with Statement of
Financial Accounting Standards No. 115, Accounting for Certain Investments in
Debt and Equity Securities (SFAS No. 115), these investments are classified as
available-for-sale and are stated at market value. The amounts of unrealized
holding gains at December 31, 1994 are not material.

E. Property, Plant
and Equipment

In addition to its wholly owned generating units, Duquesne, together with
other electric utilities, has an ownership or leasehold interest in certain
jointly owned units. The Company is required to pay its share of the
construction and operating costs of the units. The Company's share of the
operating expenses of the units is included in the statement of consolidated
income.

The Company has a 13.74 percent ownership interest in Perry Unit 1, a nuclear
generating unit operated by Centerior Energy. During 1993, the unit had an
equivalent availability factor of 39 percent. This performance resulted from
several outages related to mechanical failures. As a result of the length of
these outages, the PUC imposed a penalty for incremental replacement power
costs. The 1994 availability was 39 percent. This performance resulted from
several outages As a result of the length of these outages, the PUC imposed a 
penalty for incremental replacement power costs. The 1994 equivalent 
availability factor was 44 percent. This performance resulted from an extended 
outage in August 1994 through the balance of 1994, Perry operated at full 
capacity except for short durations of reduced power for testing and minor 
on-line maintenance activities.

CEI has previously submitted to the Nuclear REgulatory Commission an action 
plan, called the Perry Course of Action (PCA), designed by CEI to ``correct 
identified management, technical, and programmatic deficiencies'' at the plant 
over roughly a three-year period, and to ``correct the downward trending 
performance'' of Perry. CEI management represents to us that

                                       28
<PAGE>
 
the PCA is on schedule and will be an effective program to insure that Perry is 
in conformance with industry standards for boiling bring the plant back
to a performance level that meets industry standards for boiling water reactors.
The Company cannot predict the ultimate cost, timing or effectiveness of the
PCA, and is continuing to closely monitor the situation.

F. Rate Matters 

1987 Rate Case
------------------------------------------------------------------------------

In March 1988, the PUC adopted a rate order that increased the
Company's utility revenues by $232 million annually. This rate increase was
phased-in from April 1988 through April 1994. Deficiencies in current revenues
which resulted from the phase-in plan were included in the consolidated income
statement as deferred revenues. Deferred revenues were recorded on the balance
sheet as a regulatory asset. As customers were billed for deficiencies related
to prior periods, this regulatory asset was reduced. As designed, the phase-in
plan provided for carrying charges (at the after-tax AFC rate) on revenues
deferred for future recovery. The Company recovered previously deferred revenues
and carrying charges of approximately $315 million during the phase-in period
which concluded in April of 1994.

At this time, the Company has no pending base rate case and has no immediate
plans to file a base rate case.


Regulatory Assets
------------------------------------------------------------------------------

As a result of the 1987 Rate Case, and the continued application of SFAS No. 71,
the Company records regulatory assets on its consolidated balance sheet. The
regulatory assets represent probable future revenue to the Company because
provisions for these costs are currently included, or are expected to be
included, in charges to utility customers through the ratemaking process.
Management will continue to evaluate significant changes in the regulatory and
competitive environment to assess the Company's overall consistency with the
criteria of SFAS No. 71.

Deferred Rate Synchronization Costs
------------------------------------------------------------------------------

In the 1987 Rate Case, the PUC approved the Company's petition to defer
initial operating and other costs of Perry Unit 1 and Beaver Valley Unit 2. The
Company deferred the costs incurred from November 17, 1987, when the units went
into commercial operation, until March 25, 1988, when a rate order was issued.
In its order, the PUC deferred ruling on whether these costs would be
recoverable from ratepayers. The Company is not earning a return on the
deferred costs.

The Company believes that these deferred costs are recoverable. In 1990, the
PUC permitted another Pennsylvania utility recovery of such costs over a
10-year period.

Extraordinary Property Loss
------------------------------------------------------------------------------

The Company abandoned its interest in the partially-constructed Perry Unit 2
in 1986 and subsequently disposed of its interest in 1992. In the 1987 Rate
Case, the PUC approved recovery, over a 10-year period, of the Company's
original $155 million investment in Perry Unit 2. The Company is not earning a
return on the as yet unrecovered portion (approximately $23.9 million at
December 31, 1994) of its investment in the unit.

Deferred Coal Costs
------------------------------------------------------------------------------

The PUC has established two market price coal cost standards for the
Company's interests in mines that supply coal to its generating stations. One
applies only to coal delivered at the Mansfield plant. The other, the
system-wide coal cost standard, applies to coal delivered to the remainder of
the Company's system. Both standards are updated monthly to reflect prevailing
market prices for similar coal. The PUC has directed the Company to defer
recovery of the delivered cost of coal to the extent that such cost exceeds
generally prevailing market prices, as determined by the PUC, for similar coal.
The PUC allows deferred amounts to be recovered from customers when the
delivered costs of coal fall below such PUC-determined prevailing market prices.

In 1990, the PUC approved a joint petition for settlement that clarified
certain aspects of the system-wide coal cost standard and gave the Company
options to extend the standard through March 2000. In December 1991, the
Company exercised the first of two options that extended the standard through
March 1996. The unrecovered cost of coal used at Mansfield amounted to $7.3
million and $7.4 million and the unrecovered cost of coal used throughout the
system amounted to $3.4 million and $8.8 million at December 31, 1994 and 1993,
respectively.

The Company believes that all deferred coal costs will be recovered.

Warwick Mine Costs
------------------------------------------------------------------------------

The 1990 joint petition for settlement (See preceding section on deferred coal
costs.) also recognized costs at the Company's Warwick Mine, which had been on
standby since 1988, and allowed for recovery of such costs, including the costs
of ultimately closing the mine. In 1990, Duquesne entered into an agreement
under which an unaffiliated company will operate the mine until March 2000 and
sell the coal produced. Production began in late 1990. The mine reached a full
production rate in early 1991. The Warwick Mine coal reserves include both high
and low sulfur coal; the Company's contract is for medium to high sulfur (1.3
percent-2.5 percent) coal. More than 60 percent of the coal mined at Warwick
currently is used by the Company. The Company receives a royalty on sales of
Warwick coal in the open market. In the past year, the Warwick Mine supplied
slightly less than one-fifth of the coal used in the production of electricity
at the Company's wholly owned and jointly owned plants.

Costs at the Warwick Mine and the Company's investment in the mine are expected
to be recovered through the cost of coal in the ECR. Recovery is subject to the
system-wide coal cost standard. The Company also has an opportunity to earn a
return on its investment in the mine through the cost of coal during the period
of the system-wide coal cost standard, including extensions. At December 31,
1994, the Company's net investment in the mine was $18.9 million. The estimated
liability, including final site reclamation, mine water treatment and certain
labor liabilities, for mine closing is $33 million and the Company has recorded
a liability in the consolidated balance sheet of approximately $12.8 million
toward these costs.

Property Held for Future Use
------------------------------------------------------------------------------

In 1986, the PUC approved the Company's request to remove the Phillips and most
of the Brunot Island (BI) power stations from service and place them in cold
reserve. The Company expects to recover its net investment in these plants
through future electricity sales. Phillips and BI represent licensed, certified,
clean sources of electricity that will be necessary to meet expanding
opportunities in the bulk power markets. The Company believes that anticipated
growth in peak load demand for electricity within its service territory will
require additional peaking generation. The Company looks to BI to meet this
need. The Phillips power plant is an important component in the Company's
strategy to identify and serve opportunities for providing bulk power service.
With recent legislation permitting wider transmission access to bulk power
markets and with the opportunity to package a sale of power from Phillips with
the support of the Company's system, the Phillips plant can be made a highly
reliable, cost-competitive alternative for most purchasers. In summary, the
Company believes its investment in these cold-reserved plants will be necessary
in order to meet future business needs. If business opportunities do not develop
as expected, the Company will consider the sale of these assets. In the event
that market demand, transmission access or rate recovery do not support the
utilization or sale of the plants, the Company may have to write off part or all
of their costs. At December 31, 1994, the Company's net investment in
Phillips and BI was $93.0 million and $42.0 million, respectively.
 
G. Short Term
Borrowing and
Revolving Credit
Arrangements

At December 31, 1994, the Company had two extendible revolving credit agreements
including a $100 million arrangement expiring August 1995, and a $150 million
arrangement expiring October 1995. Interest rates vary, in accordance with the
option selected at the time of each borrowing. Various borrowing options are
available under the credit agreements including prime, federal funds, Eurodollar
or certificate of deposit rates. Commitment fees are based on the unborrowed
amount of the commitments. Both arrangements contain two year repayment periods
for any amounts outstanding at the expiration of the revolving credit periods.

There were no short-term borrowings during 1992. During 1994 and 1993, the
maximum short-term bank and commercial paper borrowings outstanding were $60
million and $36 million; the average daily short-term borrowings outstanding
were $36.8 million and $9.9 million; and the weighted average daily interest
rates applied to such borrowings were 5.17 percent and 3.91 percent,
respectively. At December 31, 1994 and 1993, short-term borrowings were
$60 million and $36 million.

H. Income Taxes
----------------------------------------------------------------------------

The annual federal corporate income tax returns have been audited by the
Internal Revenue Service (IRS) for the tax years through 1989. Returns filed
for the tax years 1990 to date remain subject to IRS review. The Company does
not believe that final settlement of the federal income tax returns for these
years will have a materially adverse effect on its financial position or
results of operations. The effects of the 1993 adoption of SFAS No. 109 are
discussed in Note A. Implementation of the standard involved a change in
accounting principle. The cumulative effect of $8 million on prior years was
reported in 1993 as an increase in net income. The SFAS No. 109 impact on 1993
income before cumulative effect of changes in accounting principles is
immaterial.

(a) Includes $3,201 in 1994 and $3,492 in 1993 of capital leases with
    associated obligations retired.

In 1987, the Company sold its 13.74 percent interest in Beaver Valley Unit 2;
the sale was exclusive of transmission and common facilities. The total sales
price of $537.9 million was the appraised value of the Company's interest in the
property. The Company leased back its interest in the unit for a term of 29.5
years. The lease provides for semiannual payments and is accounted for as an
operating lease. The Company is responsible under the terms of the lease for all
costs of its interest in the unit. In December 1992, the Company participated in
the refinancing of collateralized lease bonds to take advantage of lower
interest rates and reduce the annual lease payments. The bonds were originally
issued in 1987 for the purpose of partially financing the lease of Beaver Valley
Unit 2. In accordance with the Beaver Valley Unit 2 lease agreement, the Company
paid the premiums of approximately $36.4 million as a supplemental deferred rent
payment to the lessors. This amount was deferred and is being amortized over the
remaining lease term. At December 31, 1994, the deferred balance was
approximately $33.4 million.

Leased nuclear fuel is amortized as the fuel is burned. The amortization of
all other leased property is based on rental payments made. Payments for
capital and operating leases are charged to operating expenses on the statement
of consolidated income.

J. Commitments and
   Contingencies

Construction
------------------------------------------------------------------------------
The Company estimates that it will spend approximately $80 million annually on
construction during 1995, 1996 and 1997. These amounts exclude AFC, nuclear
fuel, expenditures for possible early replacement of steam generators at the
Beaver Valley Station (See ``Nuclear Litigation'' on page 35.) and expenditures
for the refurbishment of the cold-reserved units. (See ``Property Held For
Future Use'' on page 31.)

Nuclear-Related Matters
------------------------------------------------------------------------------

The Company operates two nuclear units and has an ownership interest in a third.
The operation of a nuclear facility involves special risks, potential
liabilities and specific regulatory and safety requirements. Specific
information about risk management and potential liabilities is discussed below.

Nuclear Decommissioning.  The PUC ruled that recovery of the decommissioning
costs for Beaver Valley Unit 1 could begin in 1977, and that recovery for
Beaver Valley Unit 2 and Perry Unit 1 could begin in 1988. The Company expects
to decommission Beaver Valley Unit 2 and Perry Unit 1 following the end of
their operating lives, a date that currently coincides with the expiration of
each plant's operating license. Upon expiration of the Beaver Valley Unit 1
operating license, the unit will be placed in safe storage until the expiration
of the Beaver Valley Unit 2 operating license, at which time the units may be
decommissioned together.

Based upon site specific studies finalized in 1992 for Beaver Valley Unit 2,
and in 1994 for Beaver Valley Unit 1 and Perry Unit 1, the Company's share of
the total estimated decommissioning costs, including removal and
decontamination costs, currently being used to determine the Company's cost of
service, are $122 million for Beaver Valley Unit 1, $35 million for Beaver
Valley Unit 2, and $67 million for Perry Unit 1.

In conjunction with an August 18, 1994 PUC Accounting Order, the Company has
increased the annual contribution to its decommissioning trusts by
approximately $2 million to bring the total annual funding to approximately $4
million per year. The Company plans to continue making periodic reevaluations
of estimated decommissioning costs, to provide additional
funding from time to time, and to seek regulatory approval for recognition
of these increased funding levels.

                                       34
<PAGE>
 
Nuclear Insurance.  All of the companies with an interest in the Beaver Valley
Power Station maintain the maximum available nuclear insurance for the $5.9
billion total investment in Beaver Valley Units 1 and 2. The insurance program
provides $2.8 billion for property damage, decommissioning, and decontamination
liabilities. Similar property insurance is held by the joint owners of the Perry
Plant for their $5.5 billion total investment in Perry Unit 1. The Company would
be responsible for its share of any damages in excess of insurance coverage. In
addition, if the property damage reserves of Nuclear Electric Insurance Limited
(NEIL), an industry mutual, are inadequate to cover claims arising from an
incident at any United States nuclear site covered by that insurer, the Company
could be assessed retrospective premiums totaling a maximum of $6.5 million.

The Price-Anderson Amendments to the Atomic Energy Act limit public liability
from a single incident at a nuclear plant to $8.9 billion. The Company has
purchased $200 million of insurance, the maximum amount available, which
provides the first level of financial protection.

Additional protection of $8.3 billion would be provided by an assessment of up
to $75.5 million per incident on each nuclear unit in the United States. The
Company's maximum total assessment, $56.6 million, which is based upon its
ownership interests in nuclear generating stations, would be limited to a
maximum of $7.5 million per incident per year. A further surcharge of

5 percent could be levied if the total amount of public claims exceeded the
funds provided under the assessment program. Additionally, a state premium tax
(typically 3 percent) would be charged on the assessment and surcharge. Finally,
the United States Congress could impose other revenue-raising measures on the
nuclear industry if funds prove insufficient to pay claims.

The Company carries extra expense insurance; coverage includes the incremental
cost of any replacement power purchased (in addition to costs that would have
been incurred had the units been operating) and other incidental expense after
the occurrence of certain types of accidents at its nuclear units. The amounts
of the coverage are 100 percent of the estimated extra expense per week during
the 52-week period starting 21 weeks after an accident and 80 percent of such
estimate per week for the following 104 weeks. The amount and duration of actual
extra expense could substantially exceed insurance coverage.

Nuclear Litigation.  In 1991, Pennsylvania Power Company, Ohio Edison Company,
Cleveland Electric Illuminating Company, Toledo Edison Company and the Company
were joined in the litigation against Westinghouse Electric Corporation
(Westinghouse) in the United States District Court for the Western District of
Pennsylvania. In the suit, the owners allege that six steam generators supplied
by Westinghouse for Beaver Valley Units 1 and 2 contain serious design defects
in particular defects causing tube corrosion and cracking.

Steam generator maintenance costs have increased as a result of these defects
and are likely to continue increasing. The condition of the steam generators is
being monitored closely. Replacement of the Beaver Valley Unit 1 steam generator
defective components may occur as early as 1997. While the Company has not yet
completed a detailed, site-specific study, replacement cost per unit is
estimated to be approximately $125 million. Other utilities with similar units
have replaced steam generators at comparable costs. To date, twelve additional
lawsuits have been brought by other utility companies around the country against
Westinghouse for similar problems with Westinghouse steam generators. A jury
trial began September 12, 1994 in Federal District Court in Western
Pennsylvania.

On October 24, 1994, the Court dismissed four of the five claims against
Westinghouse, leaving only the fraud claim. On December 6, 1994, the jury
rendered a verdict in favor of Westinghouse on the fraud count. On January 5,
1995, the owners of the Beaver Valley plant appealed the decision to the United
States Court of Appeals for the Third Circuit. The Company cannot predict the
outcome of this litigation; however, the Company does not believe that
resolution will have a materially adverse effect on its financial position or
results of operations. The Company's percentage interests (ownership and
leasehold) in Beaver Valley Unit 1 and in Beaver Valley Unit 2 are 47.5 percent
and 13.74 percent, respectively. The remainder of Beaver Valley Unit 1 is owned
by Ohio Edison Company and Pennsylvania Power Company.

                                       35
<PAGE>
 
The remaining interest in Beaver Valley Unit 2 is held by Ohio Edison Company,
Cleveland Electric Illuminating Company and Toledo Edison Company. The Company
operates both units on behalf of these owners.

Spent Nuclear Fuel Disposal.  Under the Nuclear Waste Policy Act of 1982, which
establishes a policy for handling and disposing of spent nuclear fuel and
requires the establishment of a final repository to accept spent fuel, contracts
for jointly owned nuclear plants have been entered into with the Department of
Energy (DOE) for permanent disposal of spent nuclear fuel and high-level
radioactive waste. The DOE has indicated that the repository will not be
available for acceptance of spent fuel before 2010. Existing on-site spent fuel
storage capacities at Beaver Valley 1, Beaver Valley 2 and Perry are expected to
be sufficient until 2014, 2010, and 2009, respectively. During 1994, the Company
increased the storage capacity at Beaver Valley 1 by equipping the spent fuel
pool with high density fuel storage racks.

Uranium Enrichment Decontamination and Decommissioning Fund.  Nuclear reactor
licensees in the United States are assessed annually for the decontamination and
decommissioning of DOE enrichment facilities. Assessments are based on the
amount of uranium a utility had processed for enrichment prior to enactment of
the National Energy Policy Act of 1992 (energy act) and are to be paid by such
utilities over a 15-year period. At December 31, 1994, the Company's liability
for contributions is approximately $9.9 million. Contributions when made are
recovered through the ECR.

Guarantees
------------------------------------------------------------------------------
The Company and the other co-owners have guaranteed certain debt and lease
obligations related to a coal supply contract for the Bruce Mansfield plant. At
December 31, 1994, the Company's share of these guarantees was $30.3 million.
The prices paid for the coal by the companies under this contract are expected
to be sufficient to meet debt and lease obligations to be satisfied in the year
2000. (See Note F.) The minimum future payments to be made by Duquesne solely in
relation to these obligations are $6.6 million in 1995, $6.2 million in 1996,
$5.9 million in 1997, $5.6 million in 1998, $5.3 million in 1999, and $4.2
million in 2000. The Company's total payments for coal purchased under the
contract were $23.3 million in 1994, $26.5 million in 1993 and $25.2 million in
1992.

Residual Waste Management Regulations
------------------------------------------------------------------------------
In 1992, the Pennsylvania Department of Environmental Resources (DER) issued
Residual Waste Management Regulations governing the generation and management of
non-hazardous waste. The Company is currently conducting tests and developing
compliance strategies. Capital compliance costs are estimated, on the basis of
information currently available, at $5 million in 1995. The expected additional
capital cost of compliance through 2000 is estimated based on current
information to be approximately $25 million; this estimate is subject to the
results of continuing ground water assessments and DER final approval of
compliance plans.

Other
------------------------------------------------------------------------------
The Company is involved in various other legal proceedings and environmental
matters. The Company believes that such proceedings and matters, in total, will
not have a materially adverse effect on its financial position or results of
operations.

K. Long-Term Debt

During 1992, the Company began issuing secured debt under a new first collateral
trust indenture. This indenture will ultimately replace Duquesne's 1947 first
mortgage bond indenture. First collateral trust bonds totaling $695 million with
an average interest rate of 6.58 percent were issued in 1993.

The pollution control notes arise from the sale of bonds by public authorities
for the purposes of financing construction of pollution control facilities at
the Company's plants or refunding previously issued bonds.

The Company is obligated to pay the principal and interest on the bonds. For
certain of the
pollution control notes, there is an annual commitment fee for an irrevocable
letter of credit.

                                       36
<PAGE>
 
Under certain circumstances, the letter of credit is available for the
payment of interest on, or redemption of, a portion of the notes. In late 1994,
pollution control notes totaling $114.1million with an average interest rate of
10.34 percent were refinanced at lower adjustable interest rates.

(d) The pollution control notes have adjustable interest rates. The interest
    rates at year-end averaged 4.3% in 1994 and 2.6% in 1993.
(e) As of January 1995, the sinking fund requirement for 1995 had been met
    and the requirements for 1996 had been partially satisfied.

At December 31, 1994, sinking fund requirements and maturities of long-term debt
outstanding for the next five years were: $10.5 million and $49.1 million in
1995; $11.0 million and $50.1 million in 1996; $10.7 million and $50.0 million
in 1997; $9.9 million and $75.0 million in 1998; and $9.9 million and $75.0
million in 1999.

Sinking fund requirements relate primarily to the first mortgage bonds and
may be satisfied by cash or the certification of property additions equal to
166O percent of the bonds required to be redeemed. During 1994, annual sinking
fund requirements of $.5 million were satisfied by cash and $10.9 million by
certification of property additions.

Total interest costs incurred were $110.7 million in 1994, $118.1 million in
1993 and $133.9 million in 1992. Of these amounts, $2.0 million in 1994, $2.0
million in 1993 and $4.7 million in 1992 were capitalized as AFC. Debt discount
or premium and related issuance expenses are amortized over the lives of the
applicable issues.

In 1992, the Company was involved in the issuance of $419.0 million of
collateralized lease bonds, which were originally issued by an unaffiliated
corporation for the purpose of partially financing the lease of Beaver Valley
Unit 2. The Company is also associated with a letter of credit securing the
lessors' equity interest in the unit and certain tax benefits. During 1994, the
Company's Beaver Valley Unit 2 lease arrangement was amended to reflect an
increase in federal income tax rates. At the same time, the associated letter
of credit securing the lessor's equity interest in the unit was increased from
$188 million to $194 million and the term of the letter of credit was extended
to 1999. If certain specified events occur, the letter of credit could be drawn
down by the owners, the leases could terminate and the bonds would become
direct obligations of the Company. At December 31, 1994 and 1993, the Company
was in compliance with all of its debt covenants.

At December 31, 1994, the fair value of the Company's long-term debt,
including current maturities and sinking fund requirements, estimated on the
basis of quoted market prices for the same or similar issues or current rates
offered to the Company for debt of the same remaining maturities, was $1,353.3
million. The principal amount included in the Company's balance sheet is
$1,441.6 million.

L. Preferred and
   Preference Stock of
   Subsidiaries

Holders of Duquesne's preferred stock are entitled to cumulative quarterly
dividends. If four quarterly dividends on any series of preferred stock are in
arrears, holders of the preferred stock are entitled to elect a majority of
Duquesne's board of directors until all dividends have been paid. At December
31, 1994, Duquesne had made all preferred stock dividend payments. Holders of
Duquesne's preference stock are entitled to receive cumulative quarterly
dividends if dividends on all series of preferred stock are paid. If six
quarterly dividends on any series of preference stock are in arrears, holders of
the preference stock are entitled to elect two of Duquesne's directors until all
dividends have been paid. At December 31, 1994, the Company had made all
dividend payments.

Outstanding preferred and preference stock is generally callable, on notice
of not less than thirty days, at stated prices plus accrued dividends. On
January 14, 1994, Duquesne called for redemption all of its outstanding shares
of $2.10 and $7.50 preference stock. None of the remaining preferred or
preference stock issues has mandatory purchase requirements.

In December 1991, the Company established an Employee Stock Ownership Plan
(ESOP) to provide matching contributions for a 401(k) Retirement Savings Plan
for Management Employees. (See Note N.) The Company issued and sold 845,070
shares of preference stock, plan series A to the trustee of the ESOP. As
consideration for the stock, the Company received a note valued at $30 million
from the trustee. The preference stock has an annual dividend rate of $2.80 per
share, and each share of the preference stock is exchangeable for one share of
DQE common stock. At December 31, 1994, $24.9 million of preference stock issued
in connection with the establishment of the ESOP had been offset, for financial
statement

purposes, by the recognition of a deferred ESOP benefit. Dividends on the
preference stock and cash contributions from the Company will be used to repay
the ESOP note. The Company made cash contributions of approximately $2.3
million for 1994, $2.1 million for 1993, and $4.9 million for 1992. These cash
contributions were the difference between the ESOP debt service and the amount
of dividends on ESOP shares (approximately $2.4 million in 1994,
$2.3 million in 1993 and $2.5 million in 1992). As shares of preference
stock are allocated to the accounts of participants in the ESOP, the Company
recognizes compensation expense, and the amount of the deferred compensation
benefit is amortized. The Company recognized compensation expense related to
the 401(k) plan of $1.8 million in 1994, $1.7 million in 1993, and $1.5 million
in 1992.

M. Common Stock

The Company or its predecessor, Duquesne, has continuously paid dividends on
common stock since 1953. The quarterly dividend declared in the fourth quarter
of 1994 was increased to $.44 per share. This annualized dividend of $1.76 per
share was increased from $1.68 per share in 1993. The annualized dividend per
share was $1.60 in 1992 and $1.52 in 1991.
 
An amendment to the Restated Articles of DQE changing the Company's Common Stock
from stock with a par value of $1.00 per share to stock having no par value, was
approved by stockholders at the Annual Meeting of Stockholders of DQE on April
20, 1994.

Dividends may be paid on DQE common stock to the extent permitted by law and
as declared by the board of directors. However, in Duquesne's Restated Articles
of incorporation, provisions relating to preferred and preference stock may
restrict the payment of Duquesne's common dividends. No dividends or
distributions may be made on Duquesne's common stock if Duquesne has not paid
dividends or sinking fund obligations on its preferred or preference stock.
Further, the aggregate amount of Duquesne's common stock dividend payments or
distributions may not exceed certain percentages of net income if the ratio of
common shareholders' equity to total capitalization is less than specified
percentages. As all of Duquesne's common stock is owned by DQE, to the extent
that Duquesne cannot pay common dividends, DQE may not be able to pay dividends
to its common shareholders. No part of the retained earnings of DQE or any of
its subsidiaries was restricted at December 31, 1994.

N. Employee Benefits
 
Retirement Plans
---------------------------------------------------------------------------
 
The Company maintains retirement plans to provide pensions for all full-time
employees. Upon retirement, an employee receives a monthly pension based on his
or her length of service and compensation. The cost of funding the pension plan
is determined by the unit credit actuarial cost method. The Company's policy is
to record this cost as an expense and to fund the pension plans by an amount
that is at least equal to the minimum funding requirements of the Employee
Retirement Income Security Act (ERISA) but not to exceed the maximum tax
deductible amount for the year. Pension costs charged to expense or construction
were $8.9 million for 1994, $9.8 million for 1993 and $11.4 million for 1992.

Retirement Savings Plan and Other Benefit Options
-------------------------------------------------------------------------------
The Company sponsors separate 401(k) retirement plans for its union-represented,
International Brotherhood of Electrical Workers (IBEW), employees and its
management employees.

The 401(k) Retirement Savings Plan for Management Employees provides that the
Company will match employee contributions to a 401(k) account up to a maximum of
6 percent of his or her eligible salary. The Company match consists of a $.25
base match per eligible contribution dollar and an additional $.25 incentive
match per eligible contribution dollar, if Board-approved targets are achieved.
The 1994 incentive target was accomplished. The Company is funding its matching
contributions to the 401(k) Retirement Savings Plan for Management Employees
with payments to an ESOP established in December 1991. (See Note L.)

                                       40
<PAGE>
 
The 401(k) Retirement Savings Plan for IBEW Represented Employees provides that
beginning in 1995, the Company will match employee contributions to a 401(k)
account up to a maximum of 4 percent of his or her eligible salary. The Company
match consists of a $.25 base match per eligible contribution dollar and an
additional $.25 incentive match per eligible contribution dollar, if certain
Non-Occupational Illness and Injury targets are met.

DQE shareholders have approved a long-term incentive plan through which the
Company may grant management employees options to purchase, during the years
1987 through 2003, up to a total of five million shares of DQE common stock at
prices equal to the fair market value of such stock on the dates the options
were granted. At December 31, 1994, approximately 2.3 million of these shares
were available for future grants.

As of December 31, 1994, 1993 and 1992, respectively, active grants totaled
1,412,000; 1,175,000; and 848,000 shares. Exercise prices of these options
ranged from $12.3125 to $34.625 at December 31, 1994 and December 31, 1993 and
from $12.3125 to $28.75 at December 31, 1992. Expiration dates of these grants
ranged from 1997 to 2004 at December 31, 1994; from 1997 to 2003 at December 31,
1993; and from 1997 to 2002 at December 31, 1992. As of December 31, 1994, 1993
and 1992, respectively, stock appreciation rights (SARs) had been granted in
connection with 793,000; 795,000; and 623,000 of the options outstanding. During
1994, 836,000 SARs were exercised; 226,000 options were exercised at prices
ranging from $12.3125 to $28.375; and 187,000 options lapsed. During 1993,
748,000 SARs were exercised; 151,000 options were exercised at prices ranging
from $12.3125 to $28.375; and 152,000 options lapsed. During 1992, 108,000 SARs
were exercised; 50,000 options were exercised at prices ranging from $12.3125 to
$26.375; and 59,000 options lapsed. Of the active grants at December 31, 1994,
1993 and 1992, respectively, 612,000; 578,000; and 232,000 were not exercisable.
 
Other Postretirement Benefits
--------------------------------------------------------------------------------

In addition to pension benefits, the Company provides certain health care
benefits and life insurance for some retired employees. Substantially all of the
Company's full-time employees may, upon attaining the age of 55 and meeting
certain service requirements, become eligible for the same benefits available to
retired employees. Participating retirees make contributions, which are adjusted
annually, to the health care plan. The life insurance plan is non-contributory.
Company-provided health care benefits terminate when covered individuals become
eligible for Medicare benefits or reach age 65, whichever comes first. The
Company funds actual expenditures for obligations under the plans on a "pay-as-
you-go basis." The Company has the right to modify or terminate the plans. As of
January 1, 1993, the Company adopted Statement of Financial Accounting Standards
No. 106, Employers' Accounting for Postretirement Benefits Other Than Pensions,
which requires the actuarially determined costs of the aforementioned
postretirement benefits to be accrued over the period from the date of hire
until the date the employee becomes fully eligible for benefits. The Company has
adopted the new standard prospectively and has elected to amortize the
transition liability over 20 years.
