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
579,000 customers within this service area, Duquesne also sells electricity to
other utilities beyond its service territory.


Regulation

     Duquesne's utility 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. This regulation is designed to provide for the
recovery of operating costs and investment and the opportunity to earn a fair
return on funds invested in the utility business. The regulatory process imposes
a time lag during which increases in operating expenses, capital costs or
construction costs may not be recovered. Duquesne is also 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 nuclear power
plants, Beaver Valley Unit 1, Beaver Valley Unit 2 and Perry Unit 1.


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.

      [GRAPH FOR 1993 ENERGY SALES BY CLASS OF CUSTOMERS APPEARS HERE]


Power Sales

     In 1993, sales to Duquesne's 20 largest customers accounted for 14.5
percent of customer revenues. Sales to USX Corporation, Duquesne's largest
customer, accounted for 3.7 percent of total 1993 customer revenues. Kilowatt-
hour (KWH) sales to ultimate customers in 1993 increased 2.4 percent in
comparison with KWH sales to ultimate customers in 1992. Above normal
temperatures in the summers of 1993 and 1991 were responsible for increased KWH
sales to residential and commercial customers in those years. Mild summer and
winter temperatures had the opposite effect on residential and commercial sales
in 1992.

     Power sales to other utilities in 1993, 1992 and 1991 were 2,820,920 KWH,
4,059,989 KWH and 2,978,662 KWH, respectively. Sales to other utilities in 1993
declined from the record level in 1992 because higher system demand and more
planned and forced generating station outages in 1993 reduced Duquesne's
generating capacity available for off-system sales. The increase from 1991 to
1992 in these short-term sales to other utilities resulted from greater
availability of transmission and generating capacity, increased demand by other
utilities for energy and Duquesne's marketing efforts. The profits from these
sales were passed through the Energy Cost Rate Adjustment Clause (ECR) to
benefit Duquesne's customers. See discussion on page 7.

     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
designed to recover Duquesne's operating expenses and investment in utility
assets and to provide a return on the investment. Current and deferred customer
revenues resulted from a $232 million rate increase granted in early 1988. The
PUC required Duquesne to phase in this increase during a six-year period. The
phase-in plan provided that, with no impact on total reported customer revenues,
rates would increase by approximately $85 million in April of each year from
1988 through 1991, remain constant in 1992 and 1993, and decrease by
approximately $85 million in April 1994. The phase-in plan also provided for
recovery of deferred revenues and carrying costs on such deferred revenues. The
rate increase has been recognized in operating revenues since March 1988. A
regulatory asset has been established for that portion of revenues yet to be
collected from customers, and carrying charges on this deferred asset have been
recognized as a component of other income in the Statement of Consolidated
Income. Duquesne expects the remaining deferred asset balance at December 31,
1993 of $28.6 million to be recovered by April 1994, the end of the phase-in
period.

     Short-term sales to other utilities are made at market rates and are
recorded in other operating revenues in the Statement of Consolidated Income.
Revenues from sales to other utilities were $50.7 million, $72.4 million and
$58.9 million in 1993, 1992 and 1991, respectively. Factors influencing record
1992 revenues correspond to those affecting KWH power sales to other utilities
(above).

     Yearly fluctuations in fuel and purchased power expense result from changes
in the cost of fuel, the mix between coal and nuclear generation, the total KWHs
generated and the effects of deferred energy costs. In 1993, the impact of the
ECR on deferred energy costs decreased fuel expense, in comparison to that for
1992. Also contributing to the 16.7 percent decline in fuel expense was a 6
percent decrease in generation that was primarily due to more scheduled and
forced generating plant outages in 1993. Fuel expense for 1992 was greater than
that for 1991 because of increased generation of electricity attributable to
record sales to other utilities. The greater fuel expense in 1992, however, was
partially offset by lower coal and nuclear fuel costs per KWH. In 1994, nuclear
fuel costs per KWH generated are expected to continue to decline, and coal costs
per KWH generated are expected to remain near the 1993 level.

     Other operating expenses were 6.5 percent higher in 1993 than in 1992. In
1993, Duquesne finalized plans to sublease the majority of its office space at
corporate headquarters; relocation of its principal business offices is
anticipated in 1994. A charge of approximately $13 million was recorded as an
operating expense to reflect the shortfall in anticipated sublease revenues from
the rental payments related to space leased through January 2003, the date the
leasing arrangements expire. Included in 1991 operating expenses was an increase
of $11.9 million in the allowance for uncollectible accounts receivable caused
by the deterioration of Duquesne's past due customer accounts and increased
collection costs.

     Maintenance expense incurred for scheduled refueling outages at Duquesne's
nuclear units is deferred and amortized over the period between scheduled
outages. During 1993, amortization of deferred nuclear refueling outage expense
increased approximately $3.5 million over the 1992 level. Contributing further
to the increase in maintenance expense in 1993 was Duquesne's change, as of
January 1, 1993, in its method of accounting for maintenance costs during major
fossil station outages. Prior to 1993, maintenance costs incurred for scheduled
major outages at fossil 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 new method was adopted to match more accurately the maintenance costs with
the revenue produced during the periods between scheduled major fossil outages.

     Depreciation and amortization expense increased in 1993 by comparison with
that for 1992 and 1991. The increase was primarily a result of an increase in
depreciable property.

     Taxes other than income taxes decreased in 1993 primarily as a result of a
favorable resolution of property tax assessments retroactive to 1987. Also in
1993, Duquesne recorded, on the basis of this revised assessment, the expected
refunds of these overpayments in prior years. By comparison with those for 1991,
taxes other than income taxes decreased in 1992 as the result of favorable
resolution of capital stock tax, gross receipts tax and sales tax matters.

     Income taxes increased in 1993 as a result of an increase in taxable income
and a 1 percent increase in the corporate federal income tax rate.

Other Income and Deductions

     Other income decreased in 1993, in comparison with that for 1992, as a
result of a decrease of approximately $13 million in carrying charges on
deferred revenues. During 1993, the deferred revenue balance upon which carrying
charges are earned declined in comparison with that for 1992 and since April
1993, Duquesne has not recorded additional carrying charges on deferred
revenues. (See the discussion of the phase-in plan under the section on Power
Sales on page 2.)

     Income taxes related to other income decreased $15 million in 1993, in
comparison with those for 1992, because of a favorable settlement (related to
Duquesne's 1988 tax return and the consolidated 1989 tax return) with the United
States Internal Revenue Service. The remaining decrease in 1993 was caused by
lower non-operating income.

     Other income for 1992 increased, in comparison with that for 1991,
primarily as the result of an increase of $3.5 million in interest income and a
decrease of $3.7 million in fees related to Duquesne's sale of receivables.
Other income for 1991 included a $5.3 million regulatory accounting
reclassification that decreased other income, reduced depreciation expense and
had no impact on net income.


Financial Condition
- --------------------------------------------------------------------------------

Financing

     Duquesne plans to meet its current obligations and debt maturities through
1998 with funds generated from operations and through new financings. At
December 31, 1993, Duquesne was in compliance with all of its debt covenants.

     Duquesne continues to reduce capital costs by refinancing, repurchasing and
retiring securities. Since the end of 1987, annual interest expense on long-term
debt has been reduced by $55.3 million through the repurchase and refinancing of
high cost debt. Preferred and preference dividend costs have been reduced $10.6
million through the repurchase or redemption of preferred and preference stock.
During 1993, Duquesne issued $695 million of first collateral trust bonds with
maturities ranging from the year 1996 through the year 2025 and with an average
interest rate of 6.58 percent. The proceeds of these sales, together with other
funds, were used to redeem $713.7 million of first mortgage bonds with an
average interest rate of 8.16 percent.

     Specifically, on June 15, 1993, a shelf registration for the periodic sale
of up to $300 million of First Collateral Trust Bonds became effective. Duquesne
issued bonds totaling $200 million under this shelf registration and, in
conjunction with the issuance of $495 million of First Collateral Trust Bonds
under 1992 shelf registrations, redeemed the remaining balances of the following
first mortgage bonds outstanding: $99.0 million of 9.00% First Mortgage Bonds,
Series due February 1, 2017; $98.0 million of 9.50% First Mortgage Bonds, Series
due December 1, 2016; $96.4 million of 8.375% First Mortgage Bonds, Series due
April 1, 2007; $49.0 million of 9.50% First Mortgage Bonds, Series due March 1,
2005; $43.6 million of 8.625% First Mortgage Bonds, Series due April 1, 2004;
$35.0 million of 7.75% First Mortgage Bonds, Series due July 1, 2003; $32.7
million of 7.25% First Mortgage Bonds, Series due January 1, 2003; $28.5 million
of 7.50% First Mortgage Bonds, Series due June 1, 2002; $26.5 million of 7.50%
First Mortgage Bonds, Series due December 1, 2001; $34.7 million of 7.875% First
Mortgage Bonds, Series due March 1, 2001; $29.7 million of 8.75% First Mortgage
Bonds, Series due March 1, 2000; $28.6 million of 7.75% First Mortgage Bonds,
Series due July 1, 1999; $30.0 million of 7.00% First Mortgage Bonds, Series due
January 1, 1999; $34.6 million of 6.375% First Mortgage Bonds, Series due
February 1, 1998; $24.6 million of 5.25% First Mortgage Bonds, Series due
February 1, 1997; and $22.8 million of 5.125% First Mortgage Bonds, Series due
February 1, 1996.

     In June 1993, Duquesne participated in the issuance of $25 million of
Beaver County Industrial Development Authority Pollution Control Revenue Bonds.
In August 1993, Duquesne participated in the issuance of $20.5 million of Ohio
Air Quality Development Authority Pollution Control Revenue Refunding Bonds to
refund a like amount of pollution control obligations.

                                       4
<PAGE>
 
     On January 14, 1994, Duquesne redeemed all of its outstanding shares of
$2.10 preference stock and $7.50 preference stock for approximately $38 million.


Short-Term Borrowings

     Duquesne has extendible revolving credit agreements with a group of banks
totaling $225 million. The current expiration date of this credit arrangement is
September 30, 1994. Interest rates can, in accordance with the option selected
at the time of each borrowing, be based on prime, federal funds, Eurodollar or
CD rates. Commitment fees are based on the unborrowed amount of the commitments.

     There were no short-term borrowings during 1992. During 1993 and 1991, the
maximum short-term bank and commercial paper borrowings outstanding were $27
million and $66 million; the average daily short-term borrowings outstanding
were $1.6 million and $11.0 million; and the weighted average daily interest
rates applied to such borrowings were 3.42 percent and 6.36 percent,
respectively. At December 31, 1993, short-term borrowings were $11.0 million.
There were no short-term borrowing balances outstanding at December 31, 1992 or
1991.


Interest Charges

     Duquesne achieved reductions in interest charges in 1993 and 1992 through
refinancing first mortgage bonds and through obtaining lower average short-term
rates on certain tax exempt pollution control notes. Duquesne also retired $24.2
million of preferred and preference stock during 1992. Interest expense and
dividends on preferred and preference stock declined to $121 million in 1993
from $135 million in 1992 and $145 million in 1991. Interest expense and
dividends on preferred and preference stock are expected to decline in 1994 by
approximately $9 million from the 1993 level.


       [GRAPH OF INTEREST EXPENSE OF PREF. & PREF. DIVS. APPEARS HERE]


Sale of Accounts Receivable

     In 1989, Duquesne and an unaffiliated corporation entered into an agreement
that entitled Duquesne to sell and the corporation to purchase, on an ongoing
basis, up to $100 million of accounts receivable. At December 31, 1993, Duquesne
had sold $9 million of receivables. The accounts receivable sales agreement,
which expires in June 1994, is one of many sources of funds available to
Duquesne. Duquesne is currently evaluating whether to seek an extension or a
replacement of the agreement.

                                       5

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, 1993, the amount of nuclear fuel financed by Duquesne under this
arrangement totaled approximately $65 million. Duquesne plans to continue
leasing nuclear fuel to fulfill its requirements at least through 1995, the
remaining term of the related leasing arrangement.


ESOP

     As discussed in Notes C and I to Duquesne's consolidated financial
statements, effective January 1, 1992, Duquesne established an Employee Stock
Ownership Plan (ESOP) through which it will match up to $.50 (depending on
whether certain incentive targets are met) of every $1.00 an employee
contributes to the 401(k) Retirement Savings Plan for Management Employees up to
a maximum of six percent of their eligible salary. Duquesne's matching
contributions are invested in Duquesne Preference Stock which can be exchanged
for DQE Common Stock. Duquesne may purchase shares of DQE Common Stock from DQE
or on the open market to satisfy the exchange feature of the Preference Stock.


Transmission Access
- --------------------------------------------------------------------------------

     During the fourth quarter of 1993, Duquesne recognized a charge to other
income of approximately $15.2 million for its investment in the abandoned
General Public Utilities (GPU) transmission line project. On December 8, 1993,
the New Jersey Board of Regulatory Commissioners (BRC) denied a request by GPU's
subsidiary Jersey Central Power and Light Company for approval of long-term
power purchase* and operating agreements that were originally signed in 1990 by
GPU and Duquesne and further amended in 1993. The BRC rejected an administrative
law judge's recommended decision that the project be approved and, within hours
of the BRC decision, GPU terminated its participation in the project. In view of
GPU's decision, Duquesne also terminated its participation in the project and
the Pennsylvania PUC transmission line siting proceeding.

     In March of 1994, Duquesne 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).
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. In this request Duquesne has
identified a $50 million investment that would enhance and stabilize this
transmission system. APS and PJM have sixty days from the receipt of this
request to formally respond.

* For discussion of Duquesne's investment in the cold-reserved units, see
Property Held for Future Use in Note J of Duquesne's consolidated financial
statements.


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

     During 1993, Duquesne spent approximately $100 million for construction to
improve and expand its production, transmission and distribution systems.
Duquesne estimates that it will spend approximately $110 million for
construction in 1994. Construction expenditures are estimated to be $70 million
in 1995 and $80 million in 1996. These amounts exclude AFC, nuclear fuel and
expenditures for possible early replacement of steam generators at the Beaver
Valley Power Station. (See Note K to Duquesne's consolidated financial
statements.) Duquesne currently has no plans for construction of new base load
generating plants.

     Duquesne anticipates that funds for planned capital expenditures in the
next several years will be provided primarily from cash becoming available from
operations and, to a lesser degree, from additional financings. Interim
financing has been and will continue to be provided through bank borrowings and
sales of commercial paper. Substantially all funds needed for 1994 capital
expenditures are expected to be generated internally.

     See "Nuclear Fuel" on page 10 for a discussion of Duquesne's commitments
with respect to the cost of nuclear fuel as of December 31, 1993, and for each
of the years 1994 through 1998.


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 J
to Duquesne's consolidated financial statements for additional discussion of
rate-related matters.


1987 Rate Case

     In March 1988, the PUC adopted a rate order that increased Duquesne's
annual revenues by $232 million phased-in from April 1988 through April 1994.
Deficiencies which resulted from the phase-in plan in current revenues from
customers have been included in the consolidated income statement as deferred
revenues. Deferred revenues have been recorded on the balance sheet as a
deferred asset for future recovery. As customers were billed for deficiencies
related to prior periods, this deferred 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. Duquesne has not recorded additional
carrying charges on the deferred revenue balance since April 1993. Duquesne had
recovered previously deferred revenues and carrying charges of $285.9 million as
of December 31, 1993. Phase-in plan deferrals of $28.6 million remained
unrecovered as of that date. Duquesne expects to recover this remaining
unrecovered balance.

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


Energy Cost Rate Adjustment Clause (ECR)

     Duquesne defers fuel and other energy costs for recovery in subsequent
years through the ECR. The deferrals reflect the difference between the amount
that Duquesne is currently collecting from customers and its actual fuel costs.
The PUC reviews Duquesne's fuel costs annually, for the fiscal year April
through March, against the previously projected fuel costs and adjusts the ECR
for over- or under-recoveries and for two PUC-established coal cost caps. The
ECR is based on projected unit costs, is recalculated each year, and is subject
to PUC review. The adjustment includes a credit to Duquesne's customers for
profits from short-term power sales to other utilities, as well as an adjustment
for any over- or under-collections from customers that may have occurred in
prior years. The 1993 ECR reduced customer costs from 1992 levels and has
continued to reduce revenues through the first quarter of 1994 by a greater
amount than in the prior year. From April 1994 through March 1995, the ECR is
expected to reduce revenues by a lesser amount than in the prior year. This ECR
treatment is intended to have no impact on net income.


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, 1993, 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, another Pennsylvania utility was permitted recovery, with no return on the
unamortized balance, of similar costs over a 10-year period.

                                       7
<PAGE>
 
Demand-Side Management

     In March of 1994, Duquesne filed with the PUC an updated Demand-Side
Management Plan (DSM) designed to encourage customer energy conservation and
load management. Duquesne's proposed DSM programs include compact fluorescent
lighting, load management, cool storage systems, emergency generation networks
and long-term interruptible rates. The Pennsylvania Industrial Energy Coalition
filed an appeal in Commonwealth Court of Pennsylvania on December 31, 1993,
requesting reversal of the PUC order of December 13, 1993 which originated
electric utility DMS programs in Pennsylvania and allows utilities to recover
prudently incurred DSM program costs through rates. Implementation of Duquesne's
DSM plan awaits PUC approval and disposition of this appeal.


Joint Interests in Generating Units
- --------------------------------------------------------------------------------

     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 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 E to Duquesne's consolidated
financial statements.

     Duquesne owns the following fossil plants jointly with the following

     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
Edison Company has authority for Sammis Unit 7, Pennsylvania Power Company has
authority for Bruce Mansfield Units 1, 2 and 3 and Monongahela Power Company
operates Ft. Martin Unit 1. 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.


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

     At December 31, 1993, Duquesne had 4,042 employees, including 1,285
employees at the Duquesne-operated Beaver Valley Power Station. The
International Brotherhood of Electrical Workers represents 2,481 of Duquesne's
employees. The current contract runs through September 1994.


Electric Operations
- --------------------------------------------------------------------------------

     Approximately 78% of the electric energy generated by Duquesne's system
during 1993 was produced by its coal-fired generating capacity and approximately
22% by its nuclear generating capacity. Duquesne normally experiences its peak
loads in the summer. The customer system peak for 1993 of 2,499 megawatts
occurred on August 31, 1993.

     Duquesne's fossil plants operated at 83% availability in 1993 and 80% in
1992. Duquesne's nuclear plants operated at 63% availability in 1993 compared to
90% in 1992. The timing of scheduled maintenance and refueling outages, as well
as the duration of forced outages, affect availability of power plants.

     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. At that time, Duquesne's net investment in the cold-reserved
stations was $106 million. In connection with a proposed long-term power sale,
Duquesne invested in the cold-reserved plants an additional $24 million in
preservation, condition assessment and plant improvements. Duquesne's net
investment in the plants at December 31, 1993 is approximately $130 million. For
further discussion of Duquesne's investment in the cold-reserved units, see
Property Held for Future Use in "Outlook" and Note J of Duquesne's consolidated
financial statements.

     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 1993 was 10.7% 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. Peak generation on June 28, 1993 was 2,621
megawatts, which included 483 megawatts of off-system sales.

     Additional information relating to Duquesne's electric operations is set
forth on page 42 of DQE's Annual Report to Shareholders for the year ended
December 31, 1993. 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 1993, approximately 2.4 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

                                       9
<PAGE>
 
sells the coal produced. Production began in late 1990. The mine reached a full
production rate in early 1991. 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 90 percent of the coal mined at Warwick Mine currently is
used by Duquesne, although Duquesne is not precluded from selling this coal on
the open market. Duquesne receives a royalty on 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, 1993, its economically
recoverable coal reserves at Warwick Mine were 11.5 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, 1993, Duquesne's
net investment in the mine was $24.5 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 collected
approximately $8.9 million toward these costs. For further discussion of
Duquesne's investment in Warwick Mine costs, see Note J of Duquesne's
consolidated financial statements.

     During 1993, 65% 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, 1993, 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 future years ranging from 1995 through 2002.
At December 31, 1993, Duquesne's wholly owned and jointly owned generating units
had on hand an average coal supply of 45 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 coalduring the month. The PUC has directed Duquesne to defer recovery of
the delivered cost of coal over generally prevailing market prices for similar
coal. Through the ECR, however, the PUC does allow deferred amounts to be
recovered from customers when the delivered costs of coal fall below prevailing
market prices. The unrecovered cost of Mansfield coal was $7.4 million and the
unrecovered cost of the remainder of the system-wide coal was $8.8 million at
December 31, 1993. Duquesne estimates that all deferred coal costs will be
recovered. Duquesne's average cost per ton of coal consumed during the past
three years at generating units which it operates or in which it has an
ownership interest was as follows: 1993-$40.08; 1992-$40.44; and 1991-$42.49.
See Note J 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 J of Duquesne's consolidated financial statements,
is recovered from Duquesne's customers through the ECR discussed previously in
"Rate Matters" on page 7.


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 reprocessing or disposal of spent fuel.

     Adequate supplies of uranium and conversion services are under contract for
Duquesne's requirements for its jointly owned 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% of its
enrichment needs through 1998. Fuel fabrication contracts are in place to supply
reload requirements for the next three cycles for Beaver Valley Unit 1, the next
three cycles for Beaver Valley Unit 2 and the next twenty-one 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 page 8.), 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

                                       10
<PAGE>
 
Duquesne is permitted to finance up to $75 million. As of December 31, 1993, the
cost of Duquesne's nuclear fuel financed was $65 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 $18 million. The actual nuclear fuel
costs to be financed and amortized during the period 1994 through 1996 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 .918 cents per KWH in 1993, inclusive of charges associated with
spent fuel. Duquesne is recovering from its customers the costs associated with
the ultimate disposal of spent fuel. All three units presently operate on an 
18-month refueling cycle with the scheduled refueling dates established as 
follows: Beaver Valley Unit 1, October 1994; Beaver Valley Unit 2, March 1995 
and Perry Unit 1, February 1994.


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

     The PUC ruled that recovery of the decommissioning costs for Beaver Valley
Unit 1 could begin December 24, 1977 and that recovery for Beaver Valley Unit 2
and Perry Unit 1 could begin March 25, 1988. Duquesne expects to decommission
each nuclear plant at the end of its life, a date that currently coincides with
the expiration of each plant's operating license. (See Note L to Duquesne's
consolidated financial statements.) The total estimated decommissioning costs,
including removal and decontamination costs, being recovered in rates are $70
million for Beaver Valley Unit 1, $20 million for Beaver Valley Unit 2, and $38
million for Perry Unit 1. These amounts were based upon the most recent studies
available at the time of Duquesne's last rate case.

     Since the time of Duquesne's last rate case, site specific studies have
been performed to update the estimated decommissioning costs, in current
dollars, for each of its nuclear generating units. In 1992, Duquesne's share of
the estimated decommissioning costs for Beaver Valley Unit 2 was revised to $35
million. Duquesne's share of decommissioning costs, which is based on
preliminary site specific studies to be finalized early in 1994, is estimated to
increase to $134 million for Beaver Valley Unit 1 and to $71 million for Perry.
(See Note L to Duquesne's consolidated financial statements for additional NRC
licensing information.)

     During 1994, it is Duquesne's intention to increase 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.

     Duquesne records decommissioning costs under the category of depreciation
expense and accrues a liability, equal to that amount, for nuclear
decommissioning expense. Such nuclear decommissioning funds are deposited in
external, segregated trust accounts. Trust fund earnings increase the fund
balance and the recorded liability. The aggregate trust fund balances at the end
of 1993 totaled $18.1 million. On the Company's consolidated balance sheet, the
decommissioning trusts have been reflected in other property and investments,
and the related liability has been recorded as other deferred credits.


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
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

                                       11
<PAGE>
 
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.
An "emission allowance" permits fuel emission of one ton of sulphur dioxide
(SO\\2\\) for one year. 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 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 reductions of SO\\2\\ and oxides of
nitrogen (NO\\X\\) by 1995 and additional reductions 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.
Duquesne's plans for meeting the 1995 SO\\2\\ compliance requirements include
increasing the use of scrubbed capacity, switching to fuel with a lower sulfur
content and purchasing emission allowances. NO\\X\\ reductions under Title IV
are required by 1995 at only the Cheswick station; work to achieve the
reductions was completed in 1993. The ozone attainment provisions of Title I
of the Clean Air Act Amendments will require NO\\X\\ reductions by 1995 at
Duquesne's Elrama plant and at the jointly owned Mansfield plant. Duquesne
plans to achieve such reductions with low NO\\X\\ burner technology. Duquesne
has currently 1,187 megawatts of scrubbed capacity, including 300 megawatts at
the currently cold-reserved Phillips plant, as well as 570 megawatts of
capacity that meets the 1995 standards of the Clean Air Act amendments through
the use of low sulfur coal. The estimated capital costs to achieve 1995
compliance standards are approximately $30 million, of which approximately $15
million has already been spent. 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 NO\\X\\
burner technology; and the purchase of emission allowances. Duquesne currently
estimates that additional capital costs to comply with environmental
requirements from 1995 through the year 2000 will be approximately $20
million. This estimate is subject to the finalization of federal and state
regulations.

     Duquesne is closely monitoring other potential air quality programs and air
emission control requirements that could be imposed in the future. These areas
include additional NO\\X\\ control requirements that could be imposed on
fossil fuel plants by the Ozone Transport Commission, more stringent ambient
air quality and emission standards for SO\\2\\ and particulates, or carbon
dioxide (CO\\2\\) control measures. 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 of these programs at this time.

     In July 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 $10 million through 1995. The
expected additional capital cost of compliance from 1995 through 2000 is
approximately $25 million; this estimate is subject to the results of ground
water assessments and DER final approval of compliance plans.

     Duquesne operates the scrubbed Elrama plant and converts the scrubber
slurry to a fixated pozolonic material. This material is placed at an off-site
disposal area having approximately six years of remaining capacity.
Additionally, Duquesne owns 17 percent of the scrubbed Mansfield plant, which is
operated by Pennsylvania Power. This plant pumps a similar slurry to an off-site
impoundment where the slurry is treated by using a Calcilox fixation process.
The site has at least 14 years of remaining capacity. Both plants have limited
temporary on-site storage for flue gas desulfurization material and no permanent
on-site disposal capacity. While there is no imminent shortage of disposal
capacity, Duquesne continues to monitor this situation and to plan for future
disposal. The siting of future disposal facilities will be facilitated by the
1993 EPA determination that coal combustion waste products are not hazardous
waste and are therefore exempt from the Hazardous Waste Regulations. The second
phase of EPA's determination will consider the co-management of coal combustion
wastes with other low volume fossil fuel combustion waste streams.

                                       12
<PAGE>
 
     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 Unit 1 are expected to be sufficient until 1996, 2010,
and 2009, respectively. Duquesne is currently increasing the storage capacity at
Beaver Valley 1 by equipping the spent fuel pool with high density fuel storage
racks. Duquesne anticipates that such action will increase the spent fuel
storage capacity at Beaver Valley 1 to provide for sufficient storage through
2014.

     In October 1992, the President signed into law the National Energy Policy
Act of 1992 (energy act). The energy act addresses a wide range of energy
issues, including several matters affecting bulk power competition in the
electric utility industry. See discussion in "Outlook" below. The energy act
requires utilities (including Duquesne) that have purchased uranium enrichment
services from the DOE to collectively contribute as much as $150 million
annually (adjusted for inflation) up to a total of $2.25 billion for
decommissioning and decontamination of DOE enrichment facilities. Assessments
are based on the amount of uranium a utility had processed for enrichment prior
to enactment of the energy act and are to be paid by such utilities over a 
15-year period. The energy act states that the assessments shall be deemed a
necessary and reasonable current cost of fuel and shall be fully recoverable in
rates in all jurisdictions in the same manner as the utility's other fuel costs.
Duquesne believes these assessments will be fully recoverable through rates.
Duquesne's total estimated liability for contributions is $12.5 million.

     The Low-Level Waste Policy Act of 1980 (LLWPA) mandated that the
responsibility for the disposal of low-level radioactive waste rests with the
individual states. Most states, including Pennsylvania and Ohio, have formed
regional compacts to comply with the LLWPA by providing permanent disposal sites
for radioactive waste generated within each compact. However, plans for these
disposal sites have not progressed as anticipated in the LLWPA and it is not
certain when the regional sites will be available for disposal of waste.
Radioactive waste from Duquesne's jointly owned nuclear plants is currently
shipped to a disposal facility in South Carolina. This facility has announced
that it will not accept any additional waste from outside the Southeast Compact
after June 30, 1994. The co-owners have constructed on-site waste storage
facilities at the Beaver Valley Power Station and the Perry Power Plant for
interim storage of the plants' low-level radioactive waste. The Beaver Valley 
on-site facility is expected to be sufficient to meet site storage requirements
until regional disposal facilities become available. The Perry on-site facility
is expected to be sufficient to meet site storage requirements for a period of
five years.

     The Company believes that it is adequately reserved for all known
environmental liabilities and costs. Accordingly, the Company believes that the
ultimate outcome of these environmental matters will not have a material adverse
effect on its financial position or the results of its operations.


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

Competition

     Regulatory developments in the industry are placing increasing competitive
pressures on electric public utilities. 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. At the
current time, Duquesne has not made, and has no plans to make, any investment in
EWGs.

                                       13
<PAGE>
 
     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 to facilitate sales to other utilities. The amendments would 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 FERC may not, however, issue any order that would
unreasonably impair the continuing reliability of affected electric systems.

     Finally, the legislation allows brokers and marketers, without owning or
operating any generation or transmission facilities, to enter into the business
of buying and selling electric capacity and energy.

     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. The
effects on Duquesne of these standards and requirements cannot be determined at
this time.

     The energy act encourages increased use of alternative transportation fuels
by federal, state, city and power provider fleets. The energy act also provides
funding for development of electric vehicles and associated infrastructures. The
effects on Duquesne cannot be determined at this time.

     The nuclear-related provisions of the energy act generally encourage
further development of the nuclear power industry through a variety of measures,
including the consolidation of construction and operating license steps into one
proceeding. The impact of these provisions on Duquesne is not expected to be
material.

     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.

     In addition, increased competition may also result from the 1990 Amendments
to the Clean Air Act. Such amendments exempt from SO2 and NOX control
requirements existing units with less than 25 megawatts of generating capacity
and new or existing co-generation units supplying less than one-third of their
electric output and less than 25 megawatts for commercial sale.


Property Held for Future Use

     In 1986, the PUC approved Duquesne's request to remove the Phillips and
most of the Brunot Island power stations from service and place them in cold
reserve. Duquesne's capitalized costs and net investment in the plants at
December 31, 1993 totaled $130 million. (See Note L to Duquesne's consolidated
financial statements.)

     Duquesne expects to recover its net investment in these plants through
future 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 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 meeting market opportunities to supply long-term bulk
power. Recent legislation may permit wider transmission access to these long-
term bulk power markets. 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.

                                       14
<PAGE>
 
Retirement Plan Measurement Assumptions

     Duquesne reduced the discount rate used to determine the projected benefit
obligation on Duquesne's retirement plans at December 31, 1993 to 7 percent. The
assumed change in future compensation levels was also decreased by 0.5 percent
to reflect current market and economic conditions.

     The effect of these changes on Duquesne's retirement plan obligations is
reflected in the amounts shown in Note I to Duquesne's consolidated financial
statements. The resulting increase in related expenses for subsequent years is
not expected to be material.


Other

     Duquesne's utility operations are subject to regulation by the PUC and the
FERC. This regulation is designed to provide for the recovery of operating costs
and investment and the opportunity to earn a fair return on funds invested in
the utility business. The regulatory process imposes a time lag during which
increases in operating expenses, capital costs or construction costs may not be
recovered.

(1) Amounts represent Duquesne's share of the unit which is owned by Duquesne in
    common with one or more other electric utilities (or, in the case of Beaver
    Valley Unit 2, leased by Duquesne).

     Duquesne owns 24 transmission substations (including interests in common in
the step-up transformers at Fort Martin No. 1; Sammis No. 7; Eastlake No. 5;
Bruce Mansfield No. 1; Beaver Valley Unit 1; Beaver Valley Unit 2; Perry Unit 1;
Bruce Mansfield No. 2; and Bruce Mansfield No. 3) and 563 distribution
substations. Duquesne has 714 circuit-miles of transmission lines, comprised of
345,000, 138,000 and 69,000 volt lines. Street lighting and distribution
circuits of 23,000 volts and less include approximately 50,000 miles of lines
and cable.

     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" on page 10.

     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 Bond Indenture.


ITEM 3. LEGAL PROCEEDINGS.

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

     Beaver Valley Units 1 and 2 are jointly owned/leased generating units (See
Item 1. Business.). In 1991, the co-owners of Beaver Valley Units 1 and 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.
Duquesne is seeking monetary and corrective relief. 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. If
the corrosion and cracking continue, replacement of the steam generators could
be required prior to the ends of their 40-year design lives. Duquesne is
continuing to conduct a corrective maintenance program and to explore longer
term options, including replacement of the steam generators. While Duquesne has
no current plans to replace the steam generators and has not yet completed a
detailed, site-specific study, replacement cost per unit is estimated to be
between $100 million and $150 million. (Other utilities with similar units have
replaced steam generators at costs in this range.) Duquesne cannot predict the
outcome of this matter; however, Duquesne does not believe that resolution will
have a materially adverse effect on Duquesne's financial position or results of
operations. Duquesne'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 by Pennsylvania Power Company. The remaining interest in
Beaver Valley Unit 2 is held by Ohio Edison Company, The Cleveland Electric
Illuminating Company and The Toledo Edison Company. Duquesne operates both units
on behalf of the joint owners.


General Electric Settlement
- --------------------------------------------------------------------------------

     In January 1994, Duquesne Light Company, The Cleveland Electric
Illuminating Company, Ohio Edison Company, Pennsylvania Power Company and The
Toledo Edison Company reached a settlement in connection with a 1991 lawsuit
filed in the United States District Court in Cleveland against General Electric
Company (GE) regarding the Perry Plant. These co-owners jointly constructed
Perry Unit 1, a nuclear power plant on the southern shore of Lake Erie in Ohio
for which GE supplied the nuclear steam supply systems and other goods and
services. The out-of-court settlement disposed of a complaint filed by the co-
owners of Perry Unit 1 which included claims of breach of contract, warranty,
and duties of good faith and fair dealing, as well as constructive fraud,
negligence, misrepresentation and various RICO violations in connection with
delays and cost increases relating to the construction of Perry Unit 1. The
settlement provides for cash payments to the Perry owners and discounts on their
future purchases from GE. This settlement will not materially affect Duquesne's
results of operations in future years.

     Effective July 7, 1989, Duquesne Light Company became a wholly owned

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 1993, Duquesne
declared quarterly dividends on its common stock totaling $144 million for the
year.

Notes:    (A)  Reclassifications and adjustments including $150 million as a 
               result of the January 1, 1993 adoption of SFAS No. 109.
          (B)  Duquesne provides for depreciation of electric plant, including
               plant-related intangibles, on a straight-line basis.  
               Amortization of other intangibles is on a straight-line basis 
               over a five-year period. At December 31, 1993 depreciation was 
               computed on the basis of the following annual rates expressed as
               a percentage of original cost: production plant - 2.48% to 
               5.01%, transmission plant - 1.35% to 3.70%, distribution 
               plant - 1.10% to 4.81% and general plant - 1.82% to 4.82%.
               Amortization of capital leases is based on nuclear fuel burned
               and rental payments made. Nonutility property is depreciated 
               under the Modified Accelerated Cost Recovery System (MACRS) for
               various classes of property as defined in section 168 of the
               Internal Revenue Code.
          (C)  Represents net change in construction work in progress.

          (B)  Duquesne provides for depreciation of electric plant,
               including plant-related intangibles, on a straight-line basis.
               Amortization of other intangibles is on a straight-line basis
               over a five-year period.  At December 31, 1992 depreciation was
               computed on the basis of the following annual rates expressed 
               as a percentage of original cost:  production plant  - 2.48% 
               to 5.01%, transmission plant - 1.35% to 3.70%, distribution 
               plant - 1.10% to 4.81% and general plant - 1.82% to 4.82%. 
               Amortization of capital leases is based on nuclear
               fuel burned and rental payments made.
          (C)  Represents net change in construction work in progress.

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 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, 1993 and 1992, and the related
consolidated statements of income, retained earnings, and cash flows for each of
the three years in the period ended December 31, 1993. 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, 1993 and 1992, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1993 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 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 plant. 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 plant 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, Duquesne Light
Company records deferred energy costs to offset differences between actual
energy costs and the level of energy costs currently recovered from customers.

Energy Cost Rate Adjustment Clause (ECR)
- ----------------------------------------
Duquesne Light 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.

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 (MEGAWATT).
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 Load
- ---------
Peak load is the amount of electricity required during periods of highest
demand. 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.) is made up of five members (one a chairman)
appointed by the governor.

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

Exchange Commission (SEC).

Property, Plant and Equipment
- --------------------------------------------------------------------------------
The asset values of 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 9.6
percent in 1993, 10.3 percent in 1992, and 9.6 percent in 1991.

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 a first mortgage lien,
and substantially all of Duquesne's electric properties are subject to junior
liens.

Depreciation
- --------------------------------------------------------------------------------
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.

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 each nuclear plant at
the end of its life, a date that currently coincides with the expiration of each
plant's operating license. (See Note L.) The total estimated decommissioning
costs, including removal and decontamination costs, being recovered in rates are
$70 million for Beaver Valley Unit 1, $20 million for Beaver Valley Unit 2, and
$38 million for Perry Unit 1. These amounts were based upon the most recent
studies available at the time of Duquesne's last rate case.

Since the time of Duquesne's last rate case, site specific studies have been
performed to update the estimated decommissioning costs, in current dollars, for
each of its nuclear generating units. In 1992, Duquesne's share of the estimated
decommissioning costs for Beaver Valley Unit 2 was revised to $35 million.
Duquesne's share of decommissioning costs, which is based on preliminary site
specific studies to be finalized early in 1994, is estimated to increase to $134
million for Beaver Valley Unit 1 and to $71 million for Perry.


                                       50
<PAGE>
 
During 1994, it is Duquesne's intention to increase 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.

Duquesne records decommissioning costs under the category of depreciation
expense and accrues a liability, equal to that amount, for nuclear
decommissioning expense. Such nuclear decommissioning funds are deposited in
external, segregated trust accounts. Trust fund earnings increase the fund
balance and the recorded liability. The aggregate trust fund balances at the end
of 1993 totaled $18.1 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 deferred credits.

Maintenance
- --------------------------------------------------------------------------------
Maintenance expense incurred for scheduled refueling outages at Duquesne's
nuclear units is deferred and amortized over the period between scheduled
outages. 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 (approximately $5.4 million, net of income taxes of
approximately $3.9 million) of the change on prior years was included in income
in 1993. The effect of the change in 1993 was to reduce income, before the
cumulative effect of changes in accounting principle, by approximately $2.4
million or $.05 per share and to reduce net income, after the cumulative effect
of changes in accounting principle, by approximately $7.8 million or $.15 per
share.

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. Deferred revenues
are associated with Duquesne's 1987 rate case. (See Note J.)

Income Taxes
- --------------------------------------------------------------------------------
On January 1, 1993, Duquesne adopted Statement of Financial Accounting Standards
Number 109 (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. As a
utility, Duquesne recognizes uncollected deferred income taxes for these
deferred tax liabilities that are expected to be recovered from customers
through rates. The adoption of SFAS No. 109 on January 1, 1993 resulted in a
$700 million increase in deferred tax liabilities and the recognition of $550
million in net regulatory assets. Prior to the adoption of SFAS No. 109,
Duquesne recorded certain costs in electric plant in service net of taxes.
Because SFAS No. 109 eliminates this "net of tax" accounting, the adoption of
SFAS No. 109 also resulted in an increase in plant assets of $150 million.

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.

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. 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.

Duquesne defers fuel and other energy expenses for recovery through the ECR in
subsequent years. The deferrals reflect the difference between the amount that
Duquesne is currently collecting from customers and its actual fuel costs. The
Pennsylvania Public Utility Commission (PUC) annually reviews Duquesne's fuel
costs for the fiscal year April through March, compares them to previously
projected fuel costs and adjusts the ECR for over- or under-recoveries and for
two PUC-established coal cost standards. (See Note J.)

Over- or under-recoveries from customers are recorded in the Consolidated
Balance Sheet of Duquesne as payable to, or receivable from, customers. At
December 31, 1993 and 1992, $10.1 million and $18.9 million were payable to
customers and shown as deferred energy costs.

Cash Flows
- --------------------------------------------------------------------------------
For the purpose of the statement of cash flows, Duquesne considers all highly
liquid investments maturing in three or fewer months to be cash equivalents.

Reclassifications
- --------------------------------------------------------------------------------
The 1992 and 1991 financial statements have been reclassified to conform with
accounting presentations adopted during 1993.

B. EXTRAORDINARY PROPERTY LOSS

In 1984, Duquesne, Ohio Edison Company, The Cleveland Electric Illuminating
Company, Pennsylvania Power Company and The Toledo Edison Company agreed to
minimize construction work and cash expenditures on Perry Unit 2 until several
alternatives, including resumption of construction or cancellation of the unit,
were evaluated. Duquesne abandoned its interest in the unit in 1986 and
subsequently disposed of its interest in 1992.

In 1987, 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 $39.4 million at
December 31, 1993) of its investment in the unit.

C. CAPITALIZATION

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 stockholders' 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 stockholders. No part of the retained
earnings of Duquesne was restricted at December 31, 1993.

</TABLE>

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, 1993, 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, 1993, Duquesne had
made all dividend payments.

Outstanding preferred and preference stock is generally callable, on notice of
not less than 30 days, at stated prices (See table on page 55.) plus accrued
dividends. On January 14, 1994, Duquesne called for redemption of 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 I.) Duquesne issued and sold 845,070 shares of
redeemable 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, 1993, $27.1 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 will be used to repay
the ESOP note. During 1993, Duquesne made cash contributions of approximately
$2.1 million, the difference between the ESOP debt service and the amount of
dividends on ESOP shares (approximately $2.3 million). 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. In 1993, Duquesne recognized $1.7 million of compensation
expense related to the 401(k) plan.

Long-Term Debt
- --------------------------------------------------------------------------------
At December 31, 1993, Duquesne had $1.433 billion of outstanding debt
securities; these consisted of $960 million of first collateral trust bonds, $49
million of first mortgage bonds, $418 million of pollution control notes and $6
million of debentures.

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 and $265 million, and having
weighted average interest rates of 6.58 percent and 8.04 percent, were issued in
1993 and 1992.

Since 1985, Duquesne has reacquired $1.561 billion of first mortgage bonds. The
difference between the purchase prices and the net carrying amounts of these
bonds has been included in the consolidated balance sheet as unamortized loss on
reacquired debt. At December 31, 1993, the balance of unamortized loss on
reacquired debt was $95.3 million.

(f) As of January 1994, the sinking fund requirement for 1995 had been met and
    the requirement for 1996 had been partially satisfied.

At December 31, 1993 and 1992, Duquesne was in compliance with all of its debt
covenants.

At December 31, 1993, sinking fund requirements and maturities of long-term debt
outstanding for the next five years were: $11.8 million and $.1 million in 1994;
$11.4 million and $49.6 million in 1995; $11.2 million and $50.1 million in
1996; $10.8 million and $50.0 million in 1997; and $10.1 million and $75.0
million in 1998.

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 1993, annual sinking fund
requirements of $.5 million were satisfied by cash and $4.8 million by
certification of property additions.

Total interest costs incurred were $118.1 million in 1993, $133.9 million in
1992 and $147.2 million in 1991. Of these amounts, which included AFC, $2.0
million in 1993, $4.7 million in 1992 and $9.3 million in 1991 were capitalized.
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' $188 million equity interest in the unit and certain tax benefits. 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.

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 June 1993, $25 million of pollution control notes were issued; the
proceeds were used to reimburse Duquesne for pollution control expenditures
related to the Beaver Valley plant. In August 1993, pollution control notes
totaling $20.5 million were refinanced at lower interest rates.

At December 31, 1993, the fair value of Duquesne's long-term debt and redeemable
preference stock approximated the carrying value. The fair value of Duquesne's
long-term debt and redeemable preference stock was estimated on the basis of (a)
quoted market prices for the same or similar issues or (b) current rates offered
to Duquesne for debt of the same remaining maturities.

At December 31, 1993, the fair market value of Duquesne's investment in DQE
common stock was $34.0 million.


D. RECEIVABLES

An arrangement between Duquesne and an unaffiliated corporation entitles
Duquesne to sell, and the corporation to purchase, up to $100 million of
Duquesne's accounts receivable. At December 31, 1993 and 1992, Duquesne had sold
$7.1 million and $66.3 million of electric customer accounts receivable and $1.9
million and $9.7 million of receivables under contracts from co-owners of
jointly owned generating facilities, respectively, to the unaffiliated
corporation. The sales agreement includes a limited recourse obligation under
which Duquesne could be required to repurchase certain of the receivables. The
maximum amount of Duquesne's contingent liability was $2.8 million at December
31, 1993.

E. LEASES

Duquesne leases nuclear fuel, a portion of a nuclear generating plant, 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 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. In December 1992, Duquesne participated
in the refinancing of collateralized lease bonds 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 rent payment to the
lessors. This amount was deferred and is being amortized over the remaining
lease term.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

Future payments due to Duquesne, as of December 31, 1993, under subleases of its
corporate headquarters space are approximately $1.7 million in 1994, $3.4
million in 1995 and $24.9 million thereafter.


E. 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 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 to 1993
income before cumulative effect of changes in accounting principle is
immaterial.

At December 31, 1993, the accumulated deferred income taxes of Duquesne totaled
$1.146 billion. As discussed in Note A, this includes the deferred tax liability
for the book and tax bases differences associated with (i) electric plant in
service of $855 million; (ii) uncollected deferred income taxes of $199 million;
and (iii) unamortized loss on reacquired debt of $40.9 million. Duquesne also
nets against this liability balance the deferred tax assets associated with (i)
investment tax credits unamortized of $45.3 million and (ii) the gain on the
sale and leaseback of Beaver Valley Unit 2 of $67.1 million. Duquesne expects to
realize these deferred tax assets.

G. SHORT-TERM BORROWING AND RELATED CREDIT AGREEMENTS

Duquesne has extendible revolving credit agreements with banks totaling $225
million. Expiration dates vary during 1994. Interest rates can, in accordance
with the option selected at the time of each borrowing, be based on prime,
federal funds, Eurodollar or CD rates. Commitment fees are based on the
unborrowed amount of the commitments.

                                     59
<PAGE>
 
There were no short-term borrowings during 1992. During 1993 and 1991, the
maximum short-term bank and commercial paper borrowings outstanding were $27
million and $66 million; the average daily short-term borrowings outstanding
were $1.6 million and $11.0 million; and the weighted average daily interest
rates applied to such borrowings were 3.42 percent and 6.36 percent,
respectively. At December 31, 1993, short-term borrowings were $11.0 million.
There were no short-term borrowings at December 31, 1992 or 1991.

I.  EMPLOYEE BENEFITS

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 $9.8 million
for 1993, $11.4 million for 1992 and $11.2 million for 1991.

Retirement Savings Plan and Other Benefit Options
- --------------------------------------------------------------------------------
Duquesne sponsors separate 401(k) retirement plans for its union-represented
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's match consists of a $.25 base match and an additional $.25 incentive
match, if targets approved by it's board of directors are met. The 1993
incentive target was met. Duquesne is funding its matching contributions with
contributions to an ESOP established in December 1991. (See Note C.)

Duquesne'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, 1993, approximately 2.9 million of these shares
were available for future grants.

As of December 31, 1993, 1992 and 1991, respectively, active grants totaled
1,174,000; 823,000; and 1,263,000 shares. Exercise prices of these options
ranged from $12.3125 to $34.1875 at December 31, 1993 and from $12.3125 to
$28.75 at December 31, 1992 and 1991. Expiration dates of these grants ranged
from 1997 to 2003 at December 31, 1993; from 1997 to 2002 at December 31, 1992;
and from 1997 to 2001 at December 31, 1991. As of December 31, 1993, 1992 and
1991, respectively, stock appreciation rights (SARs) had been granted in
connection with 778,000; 612,000; and 822,000 of the options outstanding. During
1993, 103,000 SARs were exercised; 8,500 options were exercised at prices
ranging from $12.3125 to $28.375; and 52,000 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. During 1991, 229,000 SARs
were exercised; 11,000 options were exercised at $12.3125; and 48,000 options
lapsed. Of the active grants at December 31, 1993, 1992 and 1991, respectively,
549,000; 211,000; and 526,000 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 Number 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.

                                     61
<PAGE>
 
In prior years, Duquesne recognized the cost of providing postretirement
benefits by expensing the contributions as they were made. Costs recognized
under this method in 1992 approximated $1.2 million. The new accrual method
increased the cost recognized for providing postretirement benefits to
approximately $6.0 million.

For measurement purposes, a 10.5 percent increase in the cost of covered health
care benefits was assumed as of January 1, 1993. This rate is assumed to
decrease to 5.5 percent by 1999 and remain at that level thereafter. The health
care cost trend rate assumption has a significant effect on the amounts
reported. A 1 percent increase in the health care cost trend rate would increase
the accumulated postretirement benefit obligation by $4.0 million at January 1,
1994 and the net annual cost by $0.6 million for the year. The weighted average
discount rate used in determining the accumulated postretirement benefit
obligation was 7 percent.

J. RATE MATTERS

1987 Rate Case
- --------------------------------------------------------------------------------
In March 1988, the PUC adopted a rate order that increased Duquesne's annual
revenues by $232 million to be phased in from April 1, 1988 through April 1,
1994. Deficiencies which resulted from the phase-in plan in current revenues
from customers have been included in the consolidated income statement as
deferred revenues. Deferred revenues have been recorded on the balance sheet as
a deferred asset for future recovery. As customers were billed for deficiencies
related to prior periods, this deferred 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. Since April 1993, Duquesne has not
recorded additional carrying charges on the deferred revenue balance. As of
December 31, 1993, Duquesne had recovered previously deferred revenues and
carrying charges of $285.9 million. Phase-in plan deferrals of $28.6 million

                                     62
<PAGE>
 
remained unrecovered as of that date. Duquesne expects to recover this remaining
unrecovered balance by the end of the phase-in period.

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

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 deferred ruling on whether these costs would be recoverable from ratepayers.
At December 31, 1993, 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 deferred costs are recoverable. In
1990, another Pennsylvania utility was permitted recovery, with no return on the
unamortized balance, of similar costs over a 10-year period.

Deferred Energy Costs
- --------------------------------------------------------------------------------
Duquesne defers fuel and other energy costs for recovery in subsequent years
through the ECR. The deferrals reflect the difference between the amount that
Duquesne is currently collecting from customers and its actual fuel costs. The
PUC reviews Duquesne's fuel costs annually, for the fiscal year April through
March, against the previously projected fuel costs and adjusts the ECR for over-
or under-recoveries and for two PUC-established coal cost caps.

The PUC has established market price coal cost standards for all Pennsylvania
utilities that have interests in mines that supply coal to their generating
stations. Duquesne is subject to two such 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 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 $7.4 million and the
unrecovered cost of coal used throughout the system amounted to $8.8 million at
December 31, 1993. Duquesne believes that all deferred coal costs will be
recovered.

Warwick Mine Costs
- --------------------------------------------------------------------------------
The 1990 joint petition for settlement (See preceding section on deferred energy
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; the sulfur content averages in the mid-range at 1.7 percent
- -- 1.9 percent sulfur content. More than 90 percent of the coal mined at Warwick
currently is used by Duquesne. Duquesne receives a royalty on sales of coal in
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 co-owned by
Duquesne.

Costs at the Warwick Mine and Duquesne's investment in the mine are expected to
be recovered through the ECR. Recovery is subject to the system-wide coal cost
standard. Duquesne also has an opportunity to earn, through the ECR, a return on
its investment in the mine during the period, including extensions, of the
system-wide coal cost standard. At December 31, 1993, Duquesne's net investment
in the mine was $24.5 million. The estimated current liability for mine closing
(including final site reclamation, mine water treatment and certain labor
liabilities) is $33.0 million and Duquesne has collected approximately $8.9
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's capitalized costs and net investment in the plants at
December 31, 1993 totaled $130 million. (See Note L.)

On December 8, 1993, the New Jersey Board of Regulatory Commissioners (BRC)
denied a request by General Public Utilities' (GPU) subsidiary Jersey Central
Power and Light Company for approval of the long-term power purchase and
operating agreements, originally signed in 1990, between GPU and Duquesne and
further amended earlier in 1993. The BRC rejected an administrative law judge's
recommended decision that the project be approved and, within hours of the BRC
decision, GPU terminated its participation in the project. In view of GPU's
decision not to proceed, Duquesne terminated its participation in the project
and in the PUC transmission line siting proceeding. During the fourth quarter of
1993, Duquesne recognized a charge of approximately $15.2 million for its
investment in this abandoned GPU transmission line project.

Duquesne expects to recover its net investment in these plants through future
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 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 meeting market opportunities to supply long term bulk
power.  Recent legislation may permit wider transmission access to these long-
term bulk power markets.  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.

K. COMMITMENTS AND CONTINGENCIES

Construction
- --------------------------------------------------------------------------------
Duquesne estimates that it will spend approximately $110 million on construction
during 1994. Construction expenditures are estimated to be $70 million in 1995
and $80 million in 1996. These amounts exclude AFC, nuclear fuel and
expenditures for possible early replacement of steam generators at the Beaver
Valley Station.

Westinghouse Lawsuit
- --------------------------------------------------------------------------------
In 1991, the co-owners of Beaver Valley Units 1 and 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. Duquesne is seeking
monetary and corrective relief. 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. If the corrosion
and cracking continue, replacement of the steam generators could be required
prior to the ends of their 40-year design lives. Duquesne is continuing to
conduct a corrective maintenance program and to explore longer term options,
including replacement of the steam generators. While Duquesne has no current
plans to replace the steam generators and has not yet completed a detailed,
site-specific study, replacement cost per unit is estimated to be between $100
million and $150 million. (Other utilities with similar units have replaced
steam generators at costs in this range.) Duquesne cannot predict the outcome of
this matter; however, Duquesne does not believe that resolution will have a
materially adverse effect on it's financial position or results of operations.
Duquesne'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
owned by Ohio Edison Company, Cleveland Electric Illuminating Company and Toledo
Edison Company. Duquesne operates both units on behalf of these co-owners.

Nuclear Insurance
- --------------------------------------------------------------------------------
Co-owners of 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 $2.7 billion for property damage,
decommissioning, and decontamination liabilities. Similar property insurance is
held by the joint owners of the Perry Plant for their $5.4 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
of as much as $6.5 million for up to seven years.

The Price-Anderson Amendments to the Atomic Energy Act limit public liability
from a single incident at a nuclear plant to $9.4 billion. Duquesne has
purchased $200 million of insurance, the maximum amount available, which
provides the first level of financial protection. Additional protection of $8.8
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 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
premium tax of  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.

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 it's 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 67 percent of such
estimate per week for the following 104 weeks. The amount and duration of actual
extra expense could substantially exceed insurance coverage.

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, 1993, Duquesne's share of these guarantees was $35.2 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 J.) The minimum future payments to be made by Duquesne solely in
relation to these obligations are $6.9 million in 1994, $6.6 million in 1995,
$6.3 million in 1996, $5.9 million in 1997, $5.6 million in 1998, $5.3 million
in 1999 and $4.1 million in 2000. Duquesne's total payments for coal purchased
under the contract were $26.5 million in 1993, $25.2 million in 1992 and $32.6
million in 1991.

Residual Waste Management Regulations
- --------------------------------------------------------------------------------
In July 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 for these regulations. Capital compliance costs
are estimated, on the basis of currently available information, at $10 million
through 1995. Through the year 2000, the expected additional capital cost of
compliance, which is subject to the results of ground water assessments and DER
final approval of compliance plans, is approximately $25 million.

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.

L. GENERATING UNITS

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.

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
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

                                     -2-
<PAGE>
 
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 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.

     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 his 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.

     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
predecessor or successor corporation, either directly or through the Company, or
through any such predecessor or successor corporation, or through any receiver
or a trustee in bankruptcy, whether by virtue of any constitution, statute or
rule of law or by the enforcement of any assessment or penalty or otherwise, all
such liability being, by the acceptance hereof and as part of the consideration
for the issue hereof, expressly waived and released, as more fully provided in
the Indenture.

     This bond shall not be valid or become obligatory for any purpose unless

thereunder, shall have signed the certificate of authentication endorsed hereon.

Mortgage Bond, Collateral Series E," and the form thereof shall be substantially
of the tenor and purport hereinbefore recited.  The bonds of the Forty-Fourth
Series shall be issued from time to time in an aggregate principal amount not to
exceed $300,000,000 and shall be issued as registered bonds without coupons in
denominations of $1,000 and integral multiples thereof.  The bonds of the Forty-
Fourth Series shall not bear interest except as provided in Article XIII of the
Original Indenture.  Each bond of the Forty-Fourth Series shall (a) be issued in
such principal amount, (b) mature on such date not less than nine months nor
more than forty years from its Original Issue Date (as hereinafter defined), and
(c) have such other terms and conditions, all as shall be specified by the
Company in an officers' certificate delivered to the Trustee relating to such
bond and referring to this Eighty-Fifth Supplemental Trust Indenture (such
officers' certificate being hereinafter sometimes called the "Issuance
Certificate") and substantially in the form of bond of the Forty-Fourth Series
hereinbefore recited.  The principal of and interest, if any, on each bond of
the Forty-Fourth 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-Fourth Series shall be dated as of its Original
Issue Date.  The term "Original Issue Date" as used in this Section 1.01 shall
mean, with respect to any bonds of said series of identical stated maturity and
other terms and conditions, the date of the first authentication and delivery
hereunder of such bonds.

     Section 1.02.  Each bond of the Forty-Fourth 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-Fourth 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.  The bonds of the Forty-Fourth 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

                                     -6-
<PAGE>
 
provided in the 1992 Mortgage, the bonds of the Forty-Fourth 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-Fourth 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-Fourth 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-Fourth Series has become due and payable and has not been
fully paid, and specifying the amount of funds required to make such payment.

     Section 1.05.  The bonds of the Forty-Fourth 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 1.06.  The registered holder of any bond or bonds of the Forty-
Fourth 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 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 1.07.  No charge shall be made to any registered holder of any bond
of the Forty-Fourth 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 1.08.  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-Fourth 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-Fourth Series of a denomination larger than $1,000 may be redeemed
only in integral multiples of $1,000.

                                Miscellaneous

     Section 2.01.  The holders of the bonds of the Forty-Fourth 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-Fourth 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
Eighty-Fifth Supplemental Trust Indenture or of the bonds of the Forty-Fourth
Series (except the Trustee's Certificate), and the Trustee shall incur no
responsibility in respect of such matters.

     Section 2.03.  This Eighty-Fifth Supplemental Trust Indenture shall be
construed in connection with and as part of the Indenture.

     Section 2.04.  (a)  If any provision of this Eighty-Fifth 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 Eighty-Fifth 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 Eighty-
Fifth 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 Eighty-Fifth 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 Eighty-Fifth 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 Eighty-Fifth 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 Eighty-Fifth 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.

     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 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

                                     -3-
<PAGE>
 
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.

     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
predecessor or successor corporation, either directly or through the Company, or
through any such predecessor or successor corporation, or through any receiver
or a trustee in bankruptcy, whether by virtue of any constitution, statute or
rule of law or by the enforcement of any assessment or penalty or otherwise, all
such liability being, by the acceptance hereof and as part of the consideration
for the issue hereof, expressly waived and released, as more fully provided in
the Indenture.

     This bond shall not be valid or become obligatory for any purpose unless
and until Mellon Bank, N.A., as Trustee under the Indenture, or its successor
thereunder, shall have signed the certificate of authentication endorsed hereon.

     In Witness Whereof, DUQUESNE LIGHT COMPANY has caused this bond to be
signed in its name with the facsimile signature of its Chairman of the Board,
President and Chief Executive Officer, and its corporate seal, or a facsimile
thereof, to be hereto affixed and attested with the facsimile signature of its

Pollution Control Collateral Series F."  Each bond of such series shall bear the
descriptive title "First Mortgage Bond, Pollution Control Collateral Series F,"
and the form thereof shall be substantially of the tenor and purport
hereinbefore recited.  The bonds of the Forty-Fifth Series shall be issued from
time to time in an aggregate principal amount of $25,000,000, excluding any
bonds of the Forty-Fifth 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.

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-Fifth 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-Fifth 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.

                                     -6-
<PAGE>
 
     Section 1.02.  Each bond of the Forty-Fifth 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-Fifth 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-Fifth 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-Fifth Series shall have become subject to mandatory redemption.  No
notice of such redemption shall be required to be given.

     Section 1.05.  The bonds of the Forty-Fifth 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-Fifth
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-Fifth 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-Fifth 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-Fifth 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-Fifth 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

                                     -7-
<PAGE>
 
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-
Fifth 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 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-Fifth 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

amount of bonds authenticated and delivered hereunder there shall be assigned a

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
Eighty-Sixth Supplemental Trust Indenture or of the bonds of the Forty-Fifth
Series (except the Trustee's Certificate), and the Trustee shall incur no
responsibility in respect of such matters.

     Section 2.03.  This Eighty-Sixth Supplemental Trust Indenture shall be

Trust Indenture) by any of the provisions of Sections 310 to 317, inclusive, of
said Act, such required provision shall control.

     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 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

                                      -3-
<PAGE>
 
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.

     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
predecessor or successor corporation, either directly or through the Company, or
through any such predecessor or successor corporation, or through any receiver
or a trustee in bankruptcy, whether by virtue of any constitution, statute or
rule of law or by the enforcement of any assessment or penalty or otherwise, all
such liability being, by the acceptance hereof and as part of the consideration
for the issue hereof, expressly waived and released, as more fully provided in
the Indenture.

     This bond shall not be valid or become obligatory for any purpose unless
and until Mellon Bank, N.A., as Trustee under the Indenture, or its successor
thereunder, shall have signed the certificate of authentication endorsed hereon.

     IN WITNESS WHEREOF, DUQUESNE LIGHT COMPANY has caused this bond to be
signed in its name with the facsimile signature of its Chairman of the Board,
President and Chief Executive Officer, and its corporate seal, or a facsimile
thereof, to be hereto affixed and attested with the facsimile signature of its

                                   ARTICLE I

                  FORM AND EXECUTION OF FIRST MORTGAGE BONDS,
                     POLLUTION CONTROL COLLATERAL SERIES G

and to be secured thereby, a series of bonds, designated "First Mortgage Bonds,
Pollution Control Collateral Series G."  Each bond of such series shall bear the
descriptive title "First Mortgage Bond, Pollution Control

                                      -6-
<PAGE>
 
Collateral Series G," and the form thereof shall be substantially of the tenor
and purport hereinbefore recited.  The bonds of the Forty-Sixth Series shall be
issued from time to time in an aggregate principal amount of $20,500,000,
excluding any bonds of the Forty-Sixth 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-Sixth Series shall mature on
October 1, 2027 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-Sixth 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-Sixth 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-Sixth 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-Sixth 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-Sixth 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-Sixth Series shall have become subject to mandatory redemption.  No
notice of such redemption shall be required to be given.

     SECTION 1.05.  The bonds of the Forty-Sixth 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-Sixth
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-Sixth 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.

                                      -7-
<PAGE>
 
     The Trustee may conclusively presume that the obligation of the Company to
pay the principal of the bonds of the Forty-Sixth 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-Sixth 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-Sixth 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-
Sixth 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 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-Sixth 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-Sixth 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-Sixth 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-Sixth 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-Sixth 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

                                      -8-
<PAGE>
 
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
Eighty-Seventh Supplemental Trust Indenture or of the bonds of the Forty-Sixth
Series (except the Trustee's Certificate), and the Trustee shall incur no
responsibility in respect of such matters.

     SECTION 2.03.  This Eighty-Seventh Supplemental Trust Indenture shall be
construed in connection with and as part of the Indenture.

     SECTION 2.04.  (a) If any provision of this Eighty-Seventh 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 Eighty-Seventh
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 Eighty-
Seventh 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 Eighty-Seventh 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 Eighty-Seventh 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 Eighty-Seventh 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.

     SUPPLEMENTAL INDENTURE No. 5, dated as of June 1, 1993, between DUQUESNE
LIGHT COMPANY, a corporation duly organized and existing under the laws of the
Commonwealth of Pennsylvania (hereinafter sometimes called the "Company"), and
MELLON BANK, N.A., a national banking association organized and existing under
the laws of the United States of America, trustee (hereinafter sometimes called
the "Trustee"), under the Indenture of Mortgage and Deed of Trust, dated as of
April 1, 1992 (hereinafter called the "Original Indenture"), this Supplemental
Indenture No. 5 being supplemental thereto.  The Original Indenture and any and
all indentures and instruments supplemental thereto are hereinafter sometimes
collectively called the "Mortgage."

                            Recitals of the Company

     The Original Indenture was authorized, executed and delivered by the
Company to provide for the issuance from time to time of its Securities (such
term and all other capitalized terms used herein without definition having the
meanings assigned to them in the Original Indenture), to be issued in one or
more series as contemplated therein, and to provide security for the payment of
the principal of and premium, if any, and interest, if any, on the Securities.

     The Company has heretofore executed and delivered to Mellon Bank, N.A., as
Trustee, Supplemental Indentures for the purposes recited therein and for the
purpose of creating series of Securities as set forth in Schedule A hereto.

     The Company desires to establish a series of Securities to be designated
"First Collateral Trust Bonds, Series E" to be limited in aggregate principal
amount (except as contemplated in Section 301(b) of the Original Indenture) to
$300,000,000, such series of Securities to be hereinafter sometimes called
"Series No. 4", and to amend Section 901 of the Original Indenture pursuant to
Section 1401(j) thereof.

     The Company has duly authorized the execution and delivery of this
Supplemental Indenture No. 5 to establish the Securities of Series No. 4 and to
amend Section 901 of the Original Indenture and has duly authorized the issuance
of such Securities; and all acts necessary to make this Supplemental Indenture
No. 5 a valid agreement of the Company, and to make the Securities of Series No.
4 valid obligations of the Company, have been performed.

     NOW, THEREFORE, THIS SUPPLEMENTAL INDENTURE NO. 5 WITNESSETH, that, in
consideration of the premises and of the purchase of the Securities by the
Holders thereof, and in order to secure the payment of the principal of and
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 used or to be used in or in connection with the
     generation, purchase, transmission, distribution or sale by the
     Company of electric energy (whether or not such use is the sole use of
     such property), including without limitation (a) all lands, easements,
     servitudes, licenses, permits, rights of way and other rights and
     interests in or relating to real property or the occupancy or use of
     the same; (b) all plants, generators, turbines, engines, boilers, fuel
     handling and transportation facilities, air and water pollution
     control and sewage and
<PAGE>
 
     solid waste disposal facilities and other machinery and facilities for the
     generation of electric energy; (c) all switchyards, lines, towers,
     substations, transformers and other machinery and facilities for the
     transmission of electric energy; (d) all lines, poles, conduits,
     conductors, meters, regulators and other machinery and facilities for the
     distribution of electric energy; (e) all buildings, offices, warehouses and
     other structures; and (f) all pipes, cables, insulators, ducts, tools,
     computers and other data processing and/or storage equipment and other
     equipment, apparatus and facilities and all other property, of whatever
     kind and nature, ancillary to or otherwise used or to be used in
     conjunction with any or all of the foregoing or otherwise, directly or
     indirectly, in furtherance of the generation, purchase, transmission,
     distribution or sale by the Company of electric energy;

                           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. 5 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. 5;


                           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
by the Company to other Persons prior to the date of the execution and delivery
of the Original Indenture (including, but not limited to, the Lien of the DLC
1947 Mortgage), and subject also, as to any property acquired by the Company
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
acquisition thereof (including, but not limited to, the Lien of any Class "A"
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;


                                     -2-
<PAGE>
 
     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 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

                          Fourth Series of Securities

     There is hereby created a series of Securities designated "First Collateral
Trust Bonds, Series E" and limited in aggregate principal amount (except as
contemplated in Section 301(b) of the Original Indenture) to $300,000,000.  The
form and terms of the Securities of Series No. 4 shall be established in an
Officer's Certificate.

                                  ARTICLE TWO

                        Amendment of Original Indenture

          Section 901 of the Original Indenture is hereby amended by:

          (1)  deleting the word "and" from the end of clause (x) in the first
     paragraph thereof;

          (2)  deleting the period at the end of clause (y) in the first
     paragraph thereof and adding at the end of clause (y) "; and";

          (3)  adding a new clause (z) at the end of the first paragraph thereof
     reading as follows:

               (z) an Officer's Certificate stating the Company's intention
          that, upon delivery of such Officer's Certificate, its indebtedness in
          respect of such Securities or portions thereof will have been
          satisfied.

                                                                           ; and

          (4)  deleting the second paragraph thereof and substituting therefor a
     new second paragraph reading as follows:

                    Upon receipt by the Trustee of money or Eligible
          Obligations, or both, in accordance with this Section,
          together with the documents required by clauses (x), (y) and
          (z) above, the Trustee shall, upon Company Request,
          acknowledge in writing that such Securities or portions
          thereof are deemed to have been paid

                                     -3-
<PAGE>
 
          for all purposes of this Indenture and that the entire indebtedness of
          the Company in respect thereof is deemed to have been satisfied and
          discharged.  In the event that all of the conditions set forth in the
          preceding paragraph shall have been satisfied in respect of any
          Securities or portions thereof except that, for any reason, the
          Officer's Certificate specified in clause (z) shall not have been
          delivered to the Trustee, such Securities or portions thereof shall
          not be deemed to have been paid as contemplated in such paragraph, but
          the Holders of such Securities or portions thereof shall nevertheless
          be no longer entitled to the benefit of the covenants of the Company
          under Article Six (except the covenants contained in Sections 601(a),
          602 and 603) or any other covenants made in respect of such Securities
          or portions thereof as contemplated by Section 301.

                                 ARTICLE THREE

                            Miscellaneous Provisions

          IN WITNESS WHEREOF, the parties hereto have caused this Supplemental
Indenture No. 5 to be duly executed, and their respective corporate seals to be
hereunto affixed and attested, all as of the day and year first above written.

<PAGE>
 
     NOW, THEREFORE, THIS SUPPLEMENTAL INDENTURE NO. 6 WITNESSETH, that, in
consideration of the premises and of the purchase of the Securities by the
Holders thereof, and in order to secure the payment of the principal of and
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 used or to be used in or in
     connection with the generation, purchase, transmission,
     distribution or sale by the Company of electric energy (whether
     or not such use is the sole use of such property), including
     without limitation (a) all lands, easements, servitudes,
     licenses, permits, rights of way and other rights and interests
     in or relating to real property or the occupancy or use of the
     same; (b) all plants, generators, turbines, engines, boilers,
     fuel handling and transportation facilities, air and water
     pollution control and sewage and solid waste disposal facilities
     and other machinery and facilities for the generation of electric
     energy; (c) all switchyards, lines, towers, substations,
     transformers and other machinery and facilities for the
     transmission of electric energy; (d) all lines, poles, conduits,
     conductors, meters, regulators and other machinery and facilities
     for the distribution of electric energy; (e) all buildings,
     offices, warehouses and other structures; and (f) all pipes,
     cables, insulators, ducts, tools, computers and other data
     processing and/or storage equipment and other equipment,
     apparatus and facilities and all other property, of whatever kind
     and nature, ancillary to or otherwise used or to be used in
     conjunction with any or all of the foregoing or otherwise,
     directly or indirectly, in furtherance of the generation,
     purchase, transmission, distribution or sale by the Company of
     electric energy;

                             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. 6
     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. 6;


                             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

<PAGE>
 
                                 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
by the Company to other Persons prior to the date of the execution and delivery
of the Original Indenture (including, but not limited to, the Lien of the DLC
1947 Mortgage), and subject also, as to any property acquired by the Company
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
acquisition thereof (including, but not limited to, the Lien of any Class "A"
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 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

                           Fifth Series of Securities

     There is hereby created a series of Securities designated "First Collateral
Trust Bonds, Pollution Control Series F" and limited in aggregate principal
amount (except as contemplated in Section 301(b) of the Original Indenture) to
$25,000,000.  The form and terms of the Securities of Series No. 5 shall be
established in an Officer's Certificate.

                                  ARTICLE TWO

                            Miscellaneous Provisions

     This Supplemental Indenture No. 6 is a supplement to the Mortgage.  As
supplemented by this Supplemental Indenture No. 6, the Mortgage is in all
respects ratified, approved and confirmed, and the Mortgage and this
Supplemental Indenture No. 6 shall together constitute one and the same
instrument.

                                     -3-

     NOW, THEREFORE, THIS SUPPLEMENTAL INDENTURE NO. 7 WITNESSETH, that, in
consideration of the premises and of the purchase of the Securities by the
Holders thereof, and in order to secure the payment of the principal of and
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 used or to be used in or in connection with the generation,
     purchase, transmission, distribution or sale by the Company of electric
     energy (whether or not such use is the sole use of such property),
     including without limitation (a) all land and interests in land described
     in Schedule B hereto; (b) all lands, easements, servitudes, licenses,
     permits, rights of way and other rights and interests in or relating to
     real property or the occupancy or use of the same; (c) all plants,
     generators, turbines, engines, boilers, fuel handling and transportation
     facilities, air and water pollution control and sewage and solid waste
     disposal facilities and other machinery and facilities for the generation
     of electric energy; (d) all switchyards, lines, towers, substations,
     transformers and other machinery and facilities for the transmission of
     electric energy; (e) all lines, poles, conduits, conductors, meters,
     regulators and other machinery and facilities for the distribution of
     electric energy; (f) all buildings, offices, warehouses and other
     structures; and (g) all pipes, cables, insulators, ducts, tools, computers
     and other data processing and/or storage equipment and other equipment,
     apparatus and facilities and all other property, of whatever kind and
     nature, ancillary to or otherwise used or to be used in conjunction with
     any or all of the foregoing or otherwise, directly or indirectly, in
     furtherance of the generation, purchase, transmission, distribution or sale
     by the Company of electric energy;

                           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. 7 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. 7;


                           Granting Clause Fourth

          All other property of whatever kind and nature subjected or intended

<PAGE>
 
                              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
by the Company to other Persons prior to the date of the execution and delivery
of the Original Indenture (including, but not limited to, the Lien of the DLC
1947 Mortgage), and subject also, as to any property acquired by the Company
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
acquisition thereof (including, but not limited to, the Lien of any Class "A"
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 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

                         Sixth Series of Securities

     There is hereby created a series of Securities designated "First Collateral
Trust Bonds, Pollution Control Series G" and limited in aggregate principal
amount (except as contemplated in Section 301(b) of the Original Indenture) to
$20,500,000.  The form and terms of the Securities of Series No. 6 shall be
established in an Officer's Certificate.

                                 ARTICLE TWO

                          Miscellaneous Provisions

     This Supplemental Indenture No. 7 is a supplement to the Mortgage.  As
supplemented by this Supplemental Indenture No. 7, the Mortgage is in all
respects ratified, approved and confirmed, and the Mortgage and this
Supplemental Indenture No. 7 shall together constitute one and the same

      3.01  The Operating Committee shall be that established pursuant to the 
CAPCO Administration Agreement dated as of September 14, 1967, as the same may
be amended from time to time.

      3.02  Each Party shall make available to the Operating Committee all 
data and information reasonably required to enable it to perform its duties.

      3.03  The Operating Committee shall be responsible for establishing,
maintaining and revising as necessary the Coordinated Maintenance Schedule.

      3.04  The Operating Committee shall be responsible for the establishment
and administration of rules and procedures to coordinate the operation of the
systems of the Parties to effectuate the purpose of this Agreement. Without
limiting the generality of the foregoing, the Operating Committee shall
establish rules and procedures for:

                            Operating Conditions
                            --------------------

      4.01  Each party shall operate its system continuously in parallel with 
each other Party with which it is interconnected. Unless otherwise mutually
agreed which agreement shall not be unreasonably withheld, all existing
interconnections between the systems of the Parties operating at nominal
voltages of 138,000 volts and above shall normally be operated closed. Each
Party shall maintain and operate its system so as to minimize the likelihood
and effect of disturbances on its system which might impair the service on the
system of any other Party. Each Party shall be the sole judge whether service
on its system is being impaired by conditions on the system of another Party
and may itself take, or request such other Party to take, appropriate
corrective action to restore normal operating conditions as soon as reasonably
practicable.

      Power which is supplied by one Party to another Party through
interconnections normally operated open or through a 

                                    - 8 -
<PAGE>
 
temporary interconnection point shall be compensated for by the other Party
delivering to the first Party through other interconnections equivalent Power
adjusted for losses. It is the intent of the Parties that, whenever feasible,
such compensation shall be made simultaneously with the delivery of Power
through such interconnections.

      4.02  Each Party shall use its best efforts to operate its system so as 
to aid in maintaining the frequency on the systems of the Parties at a nominal
60 Hz within the limits for normal operating deviations as established from
time to time by the Operating Committee.

      4.03  Each Party shall, to the extent practicable, operate its system so 
as to avoid the creation of objectionable operating conditions on the system
of another Party due to the transfer of megavars. Subject to the foregoing,
the Operating Committee shall (a) establish operating procedures for the
coordination of megavar supply associated with flows of Power pursuant to this
Agreement, and (b) determine the circumstances under which a Party shall
compensate another for supplying megavars in connection with flows of Power
pursuant to this Agreement and recommend the amount of such compensation.

      4.04  Each Party shall exercise reasonable care to minimize, to the extent
practicable, unscheduled deliveries or 

                                    - 9 -
<PAGE>
 
receipts of electric energy. The Parties recognize, however, that despite
their best efforts such unscheduled deliveries or receipts of electric energy
may occur. Electric energy delivered or received in such event shall be
settled for by return of equivalent energy. It shall be returned at times when
the load conditions of the returning Party are equivalent to the load
conditions of such Party at the time the energy for which it is returned was
received, unless otherwise agreed.

      4.05  The Parties recognize that in the day-to-day operation of their 
systems the transmission facilities of any Party may, as a natural result of
the physical and electrical characteristics of the interconnected network of
transmission lines of which the transmission lines of the Parties are a part,
carry Power from one portion of the system of one of the Parties to another
portion of that Party's system, or carry Power intended to be transmitted to
or from the system of one of the Parties from or to the system of another
Party or other systems. The Parties will use their best efforts to resolve
promptly any operating problems thereby created, including but not limited to
curtailing or interrupting Interruptible Load and Economy Power transactions
with other Parties and/or other systems.

      4.06  Each Party shall, to the fullest extent practicable:

                                   - 10 -

            (a)  Maintain generating units in accordance with the Coordinated
Maintenance Schedule.

            (b)  Coordinate with the other Parties the scheduled outages of
transmission facilities operating at nominal voltages of 138,000 volts or above.

            (c)  Return generation and transmission facilities to service in 
good operating condition with reasonable promptness.

            (d)  Advise the other Parties as to its maintenance practices and 
policies and any changes therein, and cooperate in attempts to accelerate or
defer maintenance of generation and transmission facilities in emergency
situations.

      4.07  Each Party shall be the sole judge as to whether, due to physical
conditions beyond its reasonable control, a generating unit operated by such
Party is unavailable for operation or unavailable for continued operation or
must be derated or temporarily removed from service; provided, however, that
unavailability for operation or continued operation, or derating, for reasons of
limitations of fuel supply for a CAPCO unit, shall be determined in accordance
with rules and procedures established by the Operating Committee.

                                   - 11 -

      4.08  Each Party shall be entitled to the full utilization, with respect 
to capacity and energy, when a CAPCO Unit is available and based on and in
proportion to the actual day-by-day operating capacity, of (a) its ownership
share of capacity in that Unit, plus (b) its entitlement to receive capacity
from another Party's ownership share in such Unit, and minus (c) its
obligation to provide capacity from such Unit. Scheduling of such capacity and
energy entitlements shall be adjusted appropriately for transmission line
losses.

               Coordinated Maintenance and CAPCO Back-Up Power
               -----------------------------------------------

      5.01  The Parties shall coordinate the outages for maintenance of all 
CAPCO Units and such other units of the Parties as are identified by the
Operating Committee and for such purpose the Coordinated Maintenance Schedule
shall be developed and maintained in accordance with rules and procedures
established pursuant to Section 3.04.

      5.02  In order to provide back-up for CAPCO Unit outages, each Party shall
have an entitlement to receive or an obligation to provide operating capacity
and associated energy in the form of CAPCO Back-Up Power.  CAPCO Back-Up Power
shall be calculated as specified in the next paragraph in this Section and shall
be compensated for as specified in Schedule A of this 

                                   - 12 -
<PAGE>
 
Agreement; provided, however, such CAPCO Back-Up Power shall not be available
for any nuclear CAPCO Unit during those periods in which such CAPCO Unit is
out of service for the reasons set forth in Schedule I.

      In the event of the forced or scheduled outage of any CAPCO Unit in
commercial operation (except those Units in cold reserve), each Party agrees
to provide or shall have the right to receive, as the case may be, CAPCO Back-
Up Power in an amount equal to the difference between such Party's ownership
share in the CAPCO Unit out of service, expressed in megawatts, and a value
determined by multiplying the Net Demonstrated Capability of the CAPCO Unit
out of service by the ratio of such Party's ownership share of the Net
Demonstrated Capability of all of the CAPCO Units in commercial operation to
the total Net Demonstrated Capability of all of the CAPCO Units in commercial
operation.

      Each Party shall use its best efforts to operate its system so as to
provide the amounts of Minimum Operating Reserve determined consistent with
the rules and procedures established pursuant to Section 3.04.

      5.03  Pursuant to rules and procedures established by the Operating 
Committee, CAPCO Back-Up Power for the next succeeding day shall be arranged
on a net basis, initially at 

                                   - 13 -
<PAGE>
 
1200 hours on the preceding day or such other time mutually agreed upon by the
Operating Committee, and shall be scheduled as requested by the receiving
Party. The receiving Party shall have the right to receive all or any part of
such Party's net entitlement to CAPCO Back-Up Power.

      5.04  Each Party is obligated to provide CAPCO Back-Up Power after 
supplying its Load and meeting its Minimum Operating Reserve, except when the
delivery of such Power would, in the judgment of the supplying Party, have to
be interrupted or reduced to preserve the integrity of or to prevent or limit
any instability on the supplying Party's system. If a Party having an
obligation to supply does not have sufficient capacity available on its own
system to meet the obligation, it is obligated to purchase capacity and
associated energy if available to provide CAPCO Back-Up Power.

      For each day that a Party is unable to fulfill all or any part of its
obligation to provide CAPCO Back-Up Power because it is supplying Power other
than CAPCO Back-Up Power to another Party or to a non-CAPCO party, except
pursuant to obligations imposed by governmental authorities, agreements referred
to in Article 19, and any additional agreements excepted by the Parties, such
Party shall pay an amount equal to twice the maximum daily demand charge for the
CAPCO Back-Up Power not provided by such Party to the other Parties to be

                                   - 14 -
<PAGE>
 
shared in proportion to the entitlements which were not fulfilled.  In the event
any Party is unable to provide CAPCO Back-Up Power in any substantial amount
over an extended period and reserves substantial CAPCO Back-Up Power from
others, the parties shall develop corrective measures such as, but not limited
to, increasing the demand charge rate.

      5.05  CAPCO Back-Up Power will be made available in proportion to Party
entitlements from supplying Parties in proportion to their obligations, and will
be made available from the least-cost available Power.  In the event that a
receiving Party or Parties reserve less than its or their entitlement of CAPCO
Back-Up Power, the remaining CAPCO Back-Up Power will be made available from the
supplying Parties in proportion to their obligations to the other receiving
Parties in proportion to their entitlements from such least-cost available
Power.  CAPCO Back-Up Power obligations not reserved by the receiving Parties
shall be deemed released to the supplying Parties.

      12.02  Billing statements rendered pursuant to Section 12.01 shall be 
due and payable in good funds the fifteenth calendar day after the billing
statement date of any such statement except that, if the 15th calendar day is
not a business day, the amount billed will be payable the next business day.
Good funds shall consist of checks received at

                                   - 22 -
<PAGE>
 
least one business day prior to the due date and wire transfers received by noon
on the due date.  Interest on unpaid billing statement amounts will be
compounded monthly and prorated for any partial month based on a 365-day year,
and will accrue at a rate equal to Chase Manhattan Bank's prime rate on the
first day of the then current calendar quarter plus two percentage points for a
period of up to one year and for any period thereafter at the higher of this
rate or a rate equal to the billing Party's cost of capital which shall consist
of the weighted average of the billing Party's long-term debt cost and preferred
stock cost rates determined for issues outstanding on December 31 of the prior
year and a common equity cost rate to be effective January 1 of each year equal
to the average return on common equity for at least 50 major electric utilities
with positive returns on common equity as reported in the prior year's December
issue of the C.A. Turner Utility Reports or as reported in the prior year's
latest issue of another report mutually agreed to by the Parties.  The weighting
for this calculation shall be the billing Party's capital structure at December
31 of the prior year, consisting solely of long-term debt, preferred stock and
common equity, as reported in such party's FERC Form 1 or in another mutually
agreed upon source.  Billing adjustments which represent amounts to be refunded
by the billing Party shall accrue interest as noted above, but billing
adjustments payable to the billing Party for additional amounts shall not accrue
interest.  Notwithstanding the foregoing, any billing

                                   - 23 -

statement shall not be due and payable to the extent that (1) any non-CAPCO
party system fails to compensate a Party for amounts owed hereunder in which
event such Party shall exercise its best efforts to collect such compensation
from such non-CAPCO party system and will not compromise or settle any claim for
such compensation without prior consent of all other affected parties, or (2)
any non-CAPCO party system's payment date is later that the fifteen days stated
above in which case such billing statement shall be due and payable on the same
date as that of the non-CAPCO party system's payment date.  To the extent that
any non-CAPCO party system compensates a party in an amount less than the amount
the non-CAPCO party system owes the Parties under the Party's billing statement
for amounts owed hereunder, each party shall be entitled to be first compensated
for Out-of-Pocket Costs associated with the transaction hereunder and so much of
the balance as will result in a sharing of the remainder among the Parties in
proportion to the amounts owed to such Parties for their respective unpaid
charges.

                                 Arbitration
                                 -----------

      16.01  Any controversy or claim arising out of this Agreement, including 
the refusal by any Party to perform the whole or any part hereof, shall, upon
demand of any Party aggrieved, be settled by an Arbitration Board, which shall
consist of three nonrepresentative members and such additional representative
members as hereinafter provided in this Section. No person shall be eligible
for appointment as a nonrepresentative member of the Arbitration Board who is
an officer, employee, shareholder of, or otherwise interested in, any Party or
any affiliate thereof or in the matter sought to be arbitrated.

                                   - 26 -
<PAGE>
 
      Unless otherwise agreed, no demand for arbitration shall be made more
than one year after the Parties have reached an impasse as to the controversy
or claim involved. The Party or Parties demanding arbitration shall serve
written notice upon the other Party or Parties to the controversy, setting
forth in detail the matter or matters with respect to which arbitration is
demanded, and shall serve copies of such notice upon any other Parties hereto.
Within a period of 10 days from the date of receipt of the aforesaid written
notice, each Party to the controversy shall appoint a representative to serve
as a member of the Arbitration Board; and, within a period of 30 days from
such date of receipt of such written notice, such representative members shall
unanimously agree upon the persons who shall serve as the three
nonrepresentative members of the Arbitration Board.

      If the representative members are not so appointed within the specified
30-day period, or if the representative members shall fail to unanimously
agree under the appointment of any or all of the three nonrepresentative
members of the Arbitration Board within the specified 30-day period, any Party
to the controversy may, upon written notice to the other Parties to the
controversy, request the American Arbitration Association to submit to the
Parties to the controversy a list from its panels of arbitrators of the names
of at least seven persons from which the nonrepresentative member or members
who have not been so appointed shall be selected in accordance with the
Commercial Arbitration Rules of such Association.

      If any Party to the controversy shall fail to appoint its representative
member within the specified 10-day period, such Party shall be deemed to have
waived its right to appoint such representative member and the Arbitration Board
shall consist of the three nonrepresentative members and such representative
members, if any, as shall have been appointed in accordance with the provisions
of this Section 16.01.

      The arbitration proceedings shall be conducted at a place, to be
designated by the Arbitration Board, within the service area of one of the
Parties to the controversy. The Arbitration Board shall afford adequate
opportunity to each Party to the controversy to present information with
respect to the controversy or claim submitted to arbitration and may request
further information from any such Party. Except as provided in the preceding
sentence, the Parties to the controversy may, by mutual agreement, specify the
rules which are to govern any proceeding before the Arbitration Board and
limit the matters to be considered by the Arbitration Board, in which event
the Arbitration Board shall be governed by the terms and conditions of such
agreement. To the extent of the absence of any such agreement specifying the
rules which are to govern any proceeding, the then current applicable rules of
the American Arbitration Association for the conduct of commercial arbitration
shall govern the proceedings.

      The arbitration shall be limited to the matter or matters specified in the
initial notice demanding arbitration and the award of the Board shall not affect
or change any provision of this Agreement or any other transaction between the
Parties.

      Procedural matters pertaining to the conduct of the arbitration and the
award of the Arbitration Board shall be determined by a majority of the
nonrepresentative members thereof; provided, however, that the representative
members shall have full right and authority to participate in all meetings and
deliberations of the Arbitration Board leading to the award. The findings and
award of the Arbitration Board, so made upon a determination of a majority of
the nonrepresentative members thereof, shall be final and conclusive with
respect to the controversy or claim submitted for arbitration and shall be
binding upon the Parties to the controversy except as otherwise provided by
law. Such award of the Arbitration Board shall specify the manner and extent
of the division of the costs of the arbitration proceedings among the Parties
to the controversy. Judgment upon the award may be entered in any court, State
or Federal, having jurisdiction.

failure of facilities, flood, earthquake, storm, fire, lightning, epidemic,
war, riot, civil disturbance, labor dispute, sabotage, restraint by Court

                   CAPCO TRANSMISSION FACILITIES AGREEMENT
                   ---------------------------------------


   THIS AGREEMENT, effective as of the 1st day of January 1, 1993, by and among
The Cleveland Electric Illuminating Company, an Ohio corporation ("CEI");
Duquesne Light Company, a Pennsylvania corporation ("DL"); Ohio Edison Company,
an Ohio corporation; Pennsylvania Power Company, a Pennsylvania corporation
("PP") and a wholly-owned subsidiary of Ohio Edison Company which Company and
its said subsidiary, except as otherwise provided herein, are considered as a
single Party for the purposes of this Agreement and referred to as ("OE"); and
The Toledo Edison Company, an Ohio corporation ("TE"), each of which is
sometimes referred to as a Party, and collectively as the Parties.


                              W I T N E S S E T H:


   WHEREAS, the Parties entered into the CAPCO Transmission Facilities Agreement
as of September 14, 1967 (herein referred to as the "Agreement"); and

   WHEREAS, the Parties entered into an Agreement on January 7, 1993, and
approved an Addendum to the CAPCO Accounting and Procedure Manual to supersede
applicable sections of the manual on a prospective basis as of January 1, 1993
(said Agreement 
<PAGE>
 
being herein referred to as the "Addendum to CAPCO Accounting and Procedure
Manual" or "Addendum"); and

   WHEREAS, the provisions of the Addendum to the CAPCO Accounting and Procedure
Manual are intended to supersede any provisions of the Agreement which conflict
with or are inconsistent with the Addendum, so that such conflicts and
inconsistencies shall be removed by appropriate written amendments to the
Agreement or by other appropriate action; and

   WHEREAS, the Parties desire to further amend the Agreement as hereinafter set
forth;

   NOW, THEREFORE, in consideration of the premises and of the mutual covenants
herein set forth, the Parties agree as follows:

   1.   Section 7.02 of the Agreement is amended to read as follows:

             The Party owning a CAPCO Line or portion thereof shall bill each 
        other Party monthly for such other Party's Investment Responsibility
        with respect thereto. The invoice date shall be established as soon as
        possible after the close of each calendar month, and the owning Party
        shall prepare and make all reasonable efforts to transmit invoices on
        or before the invoice

                                      - 2 -
<PAGE>
 
        date to each other Party for such other Party's Investment
        Responsibility. The amount billed will be payable in good funds the
        15th calendar day after the invoice date except that, if the 15th
        calendar day is not a business day, the amount billed will be payable
        the next business day. Good funds shall consist of checks received at
        least one business day prior to the due date and wire transfers
        received by noon on the due date. Interest on unpaid invoice amounts
        will be compounded monthly and prorated for any partial month based on
        a 365-day year, and will accrue at a rate equal to Chase Manhattan
        Bank's prime rate on the first day of the then current calendar
        quarter plus two percentage points for a period of up to one year and
        for any period thereafter at the higher of this rate or a rate equal
        to the billing Party's cost of capital which shall consist of the
        weighted average of the billing Party's long-term debt cost and
        preferred stock cost rates determined for issues outstanding on
        December 31 of the prior year and a common equity cost rate to be
        effective January 1 of each year equal to the average return on common
        equity for at least 50 major electric utilities with positive returns
        on common equity as reported in the prior year's December issue of the
        C.A. Turner Utility Reports or as reported in the prior year's latest
        issue of another report mutually agreed to by the Parties. The
        weighting for 

                                    - 3 -
<PAGE>
 
        this calculation shall be the billing Party's capital structure at
        December 31 of the prior year, consisting solely of long-term debt,
        preferred stock and common equity, as reported in its FERC Form 1 or
        in another mutually agreed upon source. Invoices may not be changed or
        adjusted after four years from the invoice date, and invoice amounts
        to be refunded by the billing Party shall accrue interest as noted
        above, but invoice amounts payable to the billing Party for additional
        amounts shall not accrue interest.

             To the extent practicable all charges payable or receivable under 
        this Agreement shall be offset and reduced to a net basis in order to
        provide a minimum practicable number of payments among the Parties.
        Such statements may be tendered on an estimated basis subject to
        corrective adjustments in subsequent statements.

   2.   Section 17.01 of the Agreement is amended to read as follows:

             Any waiver at any time by any Party of its rights with respect to
        any matter arising in connection with this Agreement shall not be
        deemed a waiver with respect to any subsequent similar matter. Any
        delay, short of the statutory period of limitation, in 

                                    - 4 -

with attached Exhibit C.

        3.   Investment Responsibility for a Station shall not commence earlier
than October 1, 1977.

        4.   The Party owning a Station shall bill each other Party annually for
such other Party's Investment Responsibility with respect thereto.  Bills shall
be forwarded as promptly as practicable on June 15 of each year and shall be due
and payable in good funds the fifteenth calendar day after the date of any such
statement except that, if the 15th calendar day is not a 

                                    - 8 -
<PAGE>
 
business day, the amount billed will be payable the next business day. Good
funds shall consist of checks received at least one business day prior to the
due date and wire transfers received by noon on the due date. Interest on
unpaid invoice amounts will be compounded monthly and prorated for any partial
month based on a 365-day year, and will accrue at a rate equal to Chase
Manhattan Bank's prime rate on the first day of the then current calendar
quarter plus two percentage points for a period of up to one year and for any
period thereafter at the higher of this rate or a rate equal to the billing
Party's cost of capital which shall consist of the weighted average of the
billing Party's long-term debt cost and preferred stock cost rates determined
for issues outstanding on December 31 of the prior year and a common equity
cost rate to be effective January 1 of each year equal to the average return
on common equity for at least 50 major electric utilities with positive
returns on common equity as reported in the prior year's December issue of the
C.A. Turner Utility Reports or as reported in the prior year's latest issue of
another report mutually agreed to by the Parties. The weighting for this
calculation shall be the billing Party's capital structure at December 31 of
the prior year, consisting solely of long-term debt, preferred stock and
common equity, as reported in such Party's FERC Form 1 or in another mutually
agreed upon source. Invoices may not be changed or adjusted after four years
from the invoice date, and invoice amounts to be refunded by the billing Party
shall accrue interest as noted above, but invoice amounts payable to the

                                    - 9 -
<PAGE>
 
billing Party for additional amounts shall not accrue interest.  To the extent
practicable all charges payable or receivable under this Agreement shall be
offset and reduced to a net basis in order to provide a minimum practicable
number of payments among the Parties.  Such statements may be rendered on an
estimated basis subject to corrective adjustments in subsequent statements as
noted above.

        5.   Each Party shall keep such records as may be reasonably required by
the CAPCO Operating Committee, and shall furnish to the CAPCO Operating
Committee such records, reports and other information as the CAPCO Operating
Committee may reasonably request.

   D.   General
        -------

        1.   Any waiver at any time by any Party of its rights with respect to

be deemed a waiver of such right.

        2.   No Party may, without the prior written consent of the others,
assign this Agreement, except as the same may be assigned (a) voluntarily or
otherwise under its first mortgage, or (b) to a successor to all or
substantially all of the assets of the Party by way of merger, consolidation,
sale or otherwise, where the successor assumes and becomes liable for all the
obligations of the Party hereunder.

to be several and not joint or collective, and nothing herein contained shall
ever be construed to create an association, joint venture, trust or partnership
or to impose a trust or partnership duty, obligation or liability on or with
regard to any Party.  Each Party shall be individually responsible for its own
obligations as herein provided.  No Party shall be under the control of or shall
be deemed to control another Party by virtue of this Agreement.  No Party shall
have a right of power to bind another without its or their express written
consent except as expressly provided in this Agreement.

        5.   No Party shall be considered to be in default in the performance of
any of the obligations hereunder if failure of performance shall be due to

property or business of third persons arising because of operations under this
Agreement caused or sustained on the system of a Party (the Defending Party)
shall be defended or in its discretion settled by such Party.  In the event any
such claim is brought against any other Party, such other Party shall promptly
notify the Defending Party in writing, and the Defending Party shall be entitled
to and shall take over and direct the defense and disposition of the case.  Any
amounts paid by way of settlement or in satisfaction of any judgment and all
expenses associated with such defense or settlement shall be the responsibility
of the Defending Party.  The provisions of this paragraph do not apply to claims
of the employees of any Party under any workmen's compensation law, for which
the employing Party shall be responsible.

             Each Party hereby waives any and all claims it may have against any
other Party arising from negligence and other fault of another Party in
connection with operations under this Agreement.

        7.   The Parties hereto shall be free to enter into any new microwave
sharing agreements with others, which agreements do not impair obligations under
this Agreement or the ability of a Party to perform its obligations under this
Agreement.

        8.   The obligations of each of the Parties hereunder are subject to the
obtaining of any requisite orders, approvals, 

                                   - 12 -

                      DUQUESNE LIGHT COMPANY EXECUTIVE
                  OFFICERS FOR 1993 AND SECURITY OWNERSHIP
                     OF DUQUESNE LIGHT COMPANY DIRECTORS
               AND EXECUTIVE OFFICERS AS OF FEBRUARY 23, 1994

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

  This Compensation Committee Report summarizes the 1993 components of executive
officer compensation and, with respect to certain components of compensation,
1992 performance.  All components of executive officer compensation for 1993
were approved by the Board of Directors based on the recommendations of the
Compensation Committee, which is composed entirely of non-employee directors.

COMPENSATION PHILOSOPHY

  The primary objective of the Compensation Committee is to ensure that Duquesne
Light Company's (Duquesne) 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 its shareholders, 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 shareholder value and customer satisfaction.

  The Committee also strives to simultaneously foster community participation
and support, quality leadership initiatives and innovative methodologies to
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
(adjustments to base salary, cash incentives and stock options) are based on
performance.

  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 shareholder
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.

COMPENSATION PLAN COMPONENTS

  The three components of Duquesne's executive compensation program are base
salary, annual cash and stock-option incentives and long-term incentive-based
stock options.  All stock options are granted under the Long-Term Incentive Plan
and are performance based.

  Annually, toward mid-year, the Committee reviews and determines base salary
levels, annual incentive compensation, and long-term incentive performance-based
stock option vesting, with vesting decisions intended to encourage long-term
results that increase shareholder 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 of from 0% -
40% of base salary.  Executive officers also have

                                       1
<PAGE>
 
the opportunity to earn annual incentive 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 made in 1991, with a 0% - 30%
vesting opportunity in the first year, a 0% - 60% vesting opportunity in the
second year and a 0% - 100% vesting opportunity in the third year.

  Following shareholder approval of amendments to the Long-Term Incentive Plan
to provide for stock-for-stock (reload) options, the Committee took action in
April 1993 to grant reload options to the executive officers.  The reload
options granted by the Committee attached to all outstanding options granted to
the executive officers after 1987.  The Committee believes that the grant of
reload options is consistent with Duquesne's overall compensation policy of more
closely aligning the interests of its executive officers with those of the
shareholders since reload options encourage officers to convert their options to
shares earlier.  As a result of the operation of reload options, an officer, who
exercises underlying options to which the reload options are attached, has the
opportunity to convert the reload options to shares without forfeiting the
underlying options' potential for future appreciation.

  BASE SALARY.  The base salaries of executive officers are competitively
benchmarked against a comparative industry panel of electric utility companies
of similar operating revenue size in major metropolitan areas possessing, in
most cases, both fossil and nuclear power management and operating
responsibilities.  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 1992
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 1993.  The named executive officers, other
than Mr. von Schack, received increases in base salary in 1993.

  ANNUAL INCENTIVES.  The executive officers have the opportunity to earn annual
cash and stock option incentive awards by meeting short-term operating and
financial goals.

  Individual objectives are established for each executive officer in
consultation with the CEO and approved by the Compensation Committee.  The
Committee reviews the specific results for each executive officer and the
corporate performance with the Board of Directors toward mid-year of the
following year.  The Board of Directors, upon the recommendation of the
Compensation Committee, approves the amount of annual incentive awards granted
to each executive officer based on the achievement of corporate and individual
objectives.

  Annual incentive 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 1992 was that
DQE's earnings per share must equal or exceed a specified percentage of the 1991
common stock dividend.  This goal was met in 1992.

  Each executive officer must also meet his or her individual objectives.
Specific objectives established in 1992 and considered by the Committee toward
mid-year 1993 in determining the annual incentive compensation awards earned by
the executive officers for 1992 supported one or more of five corporate
objectives, including maximizing long-term shareholder value, providing quality
service and superior customer satisfaction, cost-effective management of assets,
maintaining excellent operational performance and providing leadership in the
community.  Assessment of operational performance was based upon such measures
as generating plant availability and system reliability, for example.

  The weighting for each specific objective varies but, in the aggregate, does
not exceed 40% of base salary for Mr. von Schack 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
compensation awards earned by Mr. von Schack and the other executive officers
for 1992.

  The number of incentive stock options awarded annually under the Long-Term
Incentive Plan to executive officers is determined by multiplying their cash
incentives by a performance multiplier of 2 to 10 and then dividing the product
by the price per share of DQE Common Stock.  The size of the multiplier is based
on the amount of increase in earnings per share.  The Committee awarded annual
incentive options in the amount of 42,685  to Mr. von Schack, 13,276 to Mr.
Marshall, 14,276 to Mr. Schwass, 10,355 to Mr.

                                       2

Sieber and 11,396 to Ms. Green.  Additional options were not earned because not
all of the established performance objectives were achieved (see footnote (4) to
the Summary Compensation Table).

  An executive must wait one year before being able to exercise the first 33% of
the stock-option award.  An additional 33% is exercisable after two years and
the final increment after three years.

  LONG-TERM INCENTIVES.  Long-Term Incentive Plan performance-based stock
options were granted to executive officers under the provisions of a 1991 three-
year plan, currently ending in mid-1994, 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.  Through a performance-based vesting schedule, each
executive officer has the opportunity to earn a percentage of the three-year
grant annually.  Mr. von Schack has the opportunity to earn up to 40,000 options
and the other named officers as a group could earn up to 39,000.  The
Compensation Committee reviews the performance results and determines the amount
of the award with the approval of the Board of Directors.  No more than 30% of
the options can vest in the first year and no more than 60% can vest in the
first two years.  The long-term strategies are designed to support the long-term
corporate objectives of maximizing shareholder value, providing quality service
and superior customer satisfaction, cost-effective assets management,
maintaining excellent operational performance and providing leadership in the
community.

  With respect to the 1993 vesting for the Long-Term Incentive Plan based on
achievement of their long-term strategies, Messrs. von Schack, Marshall,
Schwass, Sieber and Ms. Green received 30% vesting.  The grant relative to these
vested stock options was disclosed in the applicable stock option grant table
included in the DQE Proxy Statement for the 1993 Annual Meeting.  Final vesting
results will be determined in mid-1994.

CEO PERFORMANCE AND COMPENSATION RATIONALE

  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 3).  Both the Committee
and the Board believe that this strengthens the relationship between corporate
performance and ultimate total compensation for the CEO, thus maximizing
shareholder value.  The Committee, in focusing on the at-risk compensation
aspect of Mr. von Schack's total compensation, made no adjustment to his base
salary in 1992 or 1993.  His current base salary level is below the average of
the comparative industry panel referred to on page 2.

  Under the leadership of Mr. von Schack, the management team continued to
achieve good results during 1993 with respect to Duquesne's long-term corporate
objectives.  In 1993 DQE and Duquesne continued to demonstrate a solid track
record of financial and operational performance.  Earnings per share increased
five cents, despite a one-time charge of sixteen cents as a result of the
termination of the GPU transmission line project.  DQE's common stock has had a
total return which consistently exceeded both the Standard & Poor's 500 and S&P
Electric Companies returns over the same period.  A full report on DQE's
financial performance can be found in the 1993 Annual Report to Stockholders.
These results are consistent with DQE's shareholder objective to "achieve
measurable and meaningful increases in the value of our shareholders'
investment."

  In fulfillment of Duquesne's customer service objective to "deliver quality
service and provide superior customer satisfaction..." customers having
interaction with Duquesne Light during 1993 rated their service experience
significantly higher than the national average for electric utilities, according
to an independent

                                       3
<PAGE>
 
monthly survey.  In fact, Duquesne Light customers experience the highest level
of service availability of all electric utilities in the state according to a
study conducted by a national consulting firm.  That study demonstrated that
Duquesne Light's service availability consistently rates in the top 25% of the
utilities nationwide.  These studies confirm the results of Duquesne's internal
benchmarked performance measures which showed that in 1993 the levels of service
reliability exceeded the corporate goals.  Also, despite record snowfalls in
March 1993 and January 1994, Duquesne Light customers experienced extremely high
levels of reliable service.  For the second year in a row, Duquesne received
Pennsylvania's "Governor's Energy Award" for its enhanced low-income customer
program focusing on reducing base-load usage and related electric costs.  This
program subsequently became Pennsylvania's entry in the U.S. Department of
Energy's national awards contest for 1994.  These results, as well as our
continuing environmental accomplishments which are discussed below, also meet
our operations objective "to be recognized for excellence in operating
performance and environmental protection."

  As a result of policies consistently directed by Mr. von Schack over the
years, Duquesne continues to be widely recognized as an environmental leader.
Examples of environmental accomplishments in 1993 include developing an
environmental strategic plan and an environmental charter, installing innovative
low NOx burners, creating and participating in various environmental stewardship
programs, including those related to education, recycling and land management,
and developing a comprehensive environmental training program for all Duquesne
employees.  Other recent examples include having the first generating plant in
the nation to reduce emissions by using natural gas to co-fire a coal-fueled
boiler, establishing a wildlife habitat, being the first investor-owned utility
to purchase emission allowance credits under the Clean Air Act amendments and
being acknowledged for its "foresight and leadership" by the Environmental
Protection Agency for participation in a program to reduce sulfur dioxide
emissions.  Duquesne received special commendations from American Forests, the
nation's oldest non-profit forestry organization, and from Allegheny County and
the Pennsylvania legislature for various environmental stewardship programs.
Duquesne remains fully committed to being an environmentally clean utility and
an innovative and forward thinking environmental leader into the future.
Throughout 1993, Duquesne maintained compliance with all environmental
regulations.

  Mr. von Schack 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 DQE'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, the members of the Compensation Committee of the Board of Directors, are
confident that our existing compensation philosophy has been effective in
attracting and retaining the management talent necessary to ensure a desirable
and consistent performance for shareholders and customers alike.

(1)  The amount of compensation set forth in columns (c)  and (g) was paid or
     awarded in the year indicated based on the prior year's performance.
     Compensation determinations are made toward mid-year of the year shown.

(2)  No incentive compensation is shown for 1993 as the annual review of
     corporate and individual performance for 1993, which will determine such
     compensation, has not occurred. The amount of any such compensation is
     determined toward mid-year of 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 1991 and 1992
     are the awards earned in those years but established and paid or deferred
     in the subsequent years.

(3)  In accordance with the transitional provisions applicable to the revised
     rules on compensation disclosure adopted by the SEC, amounts of Other
     Annual Compensation and All Other Compensation are excluded for 1991.
     Amounts of Other Annual Compensation are connected to the funding of past
     service obligations for non-qualified pension benefits earned prior to
     1993. Duquesne Light decided it was desirable, due to tax law changes and
     to ERISA requirements, to complete the funding of past service obligations
     in 1993. Amounts of All Other Compensation shown are Duquesne Light match
     contributions during 1992 and 1993 under the Duquesne Light Company 401(k)
     Retirement Savings Plan for Management Employees.

(4)  Includes total number of stock options awarded during the fiscal year, with
     or without tandem SARs, as applicable, and stock for stock (reload) options
     on option exercises, whether vested or not. See table titled Option/SAR
     Grants in Last Fiscal Year. The stock options are subject to vesting
     (exercisability) based on Duquesne Light and individual performance and
     achievement of specified goals and objectives. Of the original amount of
     1991 stock options granted, Messrs. von Schack, Marshall, Sieber and Ms.
     Green have lost 10,965; 1,554; 6,549 and 2,141 stock options, respectively.
     Of the original amount of 1992 stock options granted, Messrs. von Schack,
     Schwass, Marshall, Sieber and Ms. Green have lost 12,435; 3,569; 4,698;
     6,528 and 4,432 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 1993 under the Plan.

  Option grants in 1993 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 $34.5625
per share to $51.84 per share), shareholder value would increase an estimated
$932,929,435, while the value of the grants to the individuals listed below
would increase an estimated .22% ($2,059,570) of the total gain realized by all
shareholders.

*    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 stock options with tandem stock appreciation rights granted during 1993
     are not presently exercisable. The Compensation Committee will determine
     the number of stock option/stock appreciation rights that will vest in 1994
     based on 1993 performance. Once the number is determined, the executive
     must wait one year before being able to exercise 1/3 of the award. An
     additional 1/3 is exercisable after two years and the final increment is
     exercisable after three years. Vesting will be accelerated on the
     occurrence of a change in control as provided in the Plan. These grants
     included tandem stock appreciation rights. These grants did not include
     dividend equivalent accounts.

(2)  These represent stock for stock (reload) options received upon exercise of
     stock options by the applicable officer electing to use previously-owned
     DQE stock to exercise the options under the terms of the Plan. These reload
     options included dividend equivalent accounts.

(3)  Such exercise price, which was the fair market value on the date of grant,
     may be payable in cash or previously owned shares of DQE Common Stock. The
     price of the options or stock for stock (reload) options is the fair market
     value of DQE Common Stock on the date such options were granted.

(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 4/22/2003
     ($34.5625 strike) and 7/31/98 ($34.6250, $33.6875, and $34.1875 strikes)
     were calculated assuming an option life of 10, 5.2, 4.6, and 4.6 years
     respectively; 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 (5.85%, 5.07%, 4.97%, and 4.95%
     respectively); a quarterly dividend of $0.40 with an expected growth rate
     of 4.5% per year; and an expected stock price volatility over the same
     length of time as the option life, as reported on the grant date (19.10%,
     12.98%, 13.04% and 13.04% per month, respectively). No adjustments to the
     grant date present values have been made with respect to exercise
     restrictions, cancellation, or early exercise.

(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.  Retirement benefits are not subject to any offset or
other reduction based on the amount of any other benefits, including Social
Security.

  A Pension Service Supplement Program covering selected senior executives was
established to provide one additional service year for each full year of active
service, subject to certain vesting requirements, and to recognize compensation
in excess of any applicable ceiling on compensation earned by the executive.
The executive officers named in the Summary Compensation Table had the following
years of credited service and five-year average compensation with Duquesne Light
(including additional service credits and compensation recognized under the
Pension Service Supplement Program) as of January 1, 1994:  Mr. von Schack -- 26
years, current five-year average compensation $524,986; Mr. Schwass -- 16 years,
current five-year average compensation $195,049; Mr. Marshall  -- 17 years,
current five-year average compensation $187,259; Mr. Sieber -- 32 years, current
five-year average compensation $173,950; Ms. Green -- 12 years, current five-
year average compensation $167,305.

EMPLOYMENT AGREEMENT

  In 1992, Mr. von Schack entered into a four-year employment agreement with DQE
and Duquesne Light, subject to automatic one-year renewals unless prior written
notice of termination is given by Mr. von Schack or DQE.  The agreement
provides, among other things, for Mr. von Schack to serve as a director and
Chairman of the Board, President and Chief Executive Officer of DQE and Duquesne
Light, at an annual base salary of at least $440,000 subject to periodic review,
and for his participation in executive compensation and other employee benefit
plans of DQE and Duquesne Light.

  If Mr. von Schack 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 would receive in a cash lump sum the balance of his base salary
for the remaining term of the agreement, a bonus amount in respect of the
remaining term of the agreement calculated at a rate equivalent to his prior
year's bonus and the actuarial equivalent of the additional pension he would
have accrued had his service for pension purposes continued until the expiration
of the agreement.  In addition, Mr. von Schack would be entitled to immediate
vesting (or the redemption in cash) of all of his stock-based awards from DQE or
Duquesne Light.  The agreement also provides for continued payment of base
salary and bonus amounts for the remaining term of the agreement if Mr. von
Schack's employment is terminated due to death or disability.  In the event that
any payments, whether under the employment agreement or otherwise, would subject
Mr. von Schack to federal excise tax or interest or penalties with respect to
such excise tax, he will be entitled to be made whole for the payment of any
such taxes, interest or penalties.

ON THE COVER

Like the common light bulb, the electric utility industry is changing. 
Competition is increasing, as are options to help businesses work smarter, 
cleaner and more cost-effectively through use of electrotechnologies. In 1993, 
DQE people again demonstrated they have energy to adapt to change in their 
industry and to meet the changing needs of their customers.

To Our 
Shareholders

the company's many environmental partnerships (see page 8).

                            [PHOTO APPEARS HERE]


     Throughout 1993, our DQE team kept its focus on three basic objectives:
delivering a fair return to our shareholders; providing top quality service to
our customers; and preparing for emerging changes in the electric utility
industry. Our results continue to be good on all three fronts.

     Net income for 1993 increased $2.5 million over that for 1992, and earnings
per share rose from $2.67 in 1992 to $2.72. Since year end 1988, DQE's
earnings per share have increased 46 percent. In November, the annual dividend
was increased by 5 percent, to $1.68.

     DQE possesses an abundance of energy resources that hold long term
promise and opportunity as the market for power grows. A recent industry
forecast projects annual growth of 2 percent in electric demand through 2010.
To meet such demand, more than 210 gigawatts of additional generation will be
required. Less than 20 percent of this additional capacity currently is under
construction.

     DQE has a total of 3,374 megawatts of environmentally clean generating
capacity, of which only 2,834 megawatts currently are in service. This
generation provides what we believe is an important long term competitive
advantage and a benefit to our customers. For example, during the deep freeze
of January 1994 when rolling blackouts disrupted the lives and businesses of
millions of people in eastern and central Pennsylvania, New Jersey, Maryland,
Delaware, Virginia and the District of Columbia, Duquesne Light fortunately
did not have to institute voltage reductions or rolling blackouts.

     It was, therefore, ironic that our planned sale, to be initiated in January
1994, of 500 megawatts to General Public Utilities (GPU) did not take place.
In December 1993, GPU abruptly cancelled its three-year-old agreement to
purchase bulk power from Duquesne Light and to construct a jointly owned high
voltage transmission line. Termination of the project resulted in a charge to
DQE earnings of $15 million (16 cents per share).

     As reported to you in last year's annual report, we expect much change in
our industry because of the National Energy Policy Act of 1992. This
legislation gives federal regulators broad power to mandate the transfer of
wholesale bulk power over the nation's high voltage transmission systems. The
net result will be increased competition in the electric utility industry.

     Electric companies now have one foot in competition and one foot in
regulation. Dealing with this dichotomy requires flexible and capable
management. Our management team has demonstrated the ability to focus on
building a market and customer driven company while at the same time remaining
responsive to the requirements and obligations of state regulation. During the
last eight years, you have been kept apprised of the excellent progress we've
been able to make in positioning our company for the changes ahead.

     One strategy continuously evident in all aspects of our business is to be
prepared for the market based realities that

                "OUR FUNDAMENTAL STRATEGY IS TO BE RECOGNIZED
           FOR EXCELLENCE IN OUR OPERATIONS AND TO PROVIDE A HIGH
                      LEVEL OF CUSTOMER SATISFACTION."


the industry is experiencing. We are focused on constantly improving
performance to lower the cost of production, and our least cost planning and
innovative pricing policies reflect our commitment to deliver a competitive
product to our customers. In fact, through our continued efforts, we are
positioned to reduce average retail rates by approximately 8 percent, as of
April 1994.

     Also, the marginal cost for us to produce a kilowatt-hour of electricity is
competitive. This low cost of production enabled us to sell more than 19
percent of our output to other electric utilities in the bulk power market in
1993.

     Our fundamental strategy is to be recognized for excellence in our
operations and to provide a high level of customer satisfaction. Independent
surveys and our own internal measurements indicate that customers are highly
satisfied with the way we treat them and the quality of service. Our system
reliability is among the top 25 percent in the nation. Duquesne Light
customers experience fewer minutes of power interruptions each year than the
customers of any other utility in Pennsylvania. Our customers are getting good
value.

     This commitment to customers was put to the test in 1993 when the
"Blizzard of the Century" blanketed the eastern United States. A state-of-the-
art automated distribution system pinpointed weather related damage to
electrical equipment and allowed our operators to switch service circuits by
computer so that customers affected by the blizzard were restored to service
in quick order.

     Environmental leadership remains a strong component of our overall
strategy, and we are proud of maintaining the highest standards in this area
of public interest.

     All of our wholly owned fossil fuel units currently emit sulfur dioxide
(SO2) at a lower rate than federal standards for the year 2000. In 1993, we
completed installation of low nitrogen oxide (NOX) burners at our Cheswick
station. We will need to invest only $35 million more to meet Phase I and
Phase II SO2 and NOX Clean Air Act of 1990 requirements. Environmental
leadership represents good value for shareholders. Utility companies that have
not invested in the environmental quality of their operations over the years
will see production costs increase as they catch up with our nation's new
environmental standards.

     For reasons that are both natural and man-made, the electric utility
business will continue to be challenging. Our people are up to meeting these
challenges. We are grateful for their leadership and contributions, and to
you, our shareholders, for your continued confidence in DQE.

Energy for Change


     With passage of the National Energy Policy Act(NEPA)in 1992, we have no
doubt that change--and increasing competition--will be constants in our
industry. We know that to compete successfully in the new energy marketplace,
we must concentrate on providing high levels of customer satisfaction,
improving our performance, and reducing costs. Our longstanding corporate
objectives, highlighted on the following pages, focus our people's energies on
five key areas: shareholders, customers, employees, operations, and community.
As we work to meet these all-important objectives, we continue to demonstrate
that we have "energy for change."


Objective: 
Manage company
resources to maximize
return on Investment.


CUSTOMER SATISFACTION

     Our goal is to deliver customer value through a combination of top
quality service and helping our customers increase their efficiency and reduce
their overall operating costs.
     Independent statistics show that Duquesne Light customers annually 
experience fewer minutes of power interruptions than the customers of any 
other utility in Pennsylvania. Thanks to advanced technology and good 
old-fashioned commitment to quality service, we were able to limit the effect
on customers of extreme weather conditions in 1993 and early 1994, including 
two major winter blizzards; extended periods of hot, humid summer weather; and
record-low winter temperatures.
     When storms damage electric lines or equipment, our automated 
distribution system senses the trouble, identifies the problem area, and 
allows us to use remote control to reroute electricity almost instantly to all
customers on the circuit except those in the immediate vicinity. And for 
those customers, some very determined troubleshooters are on the scene quickly
to restore service--usually within an hour.
     We strive to provide all of our customers with a high degree of service. 
Reliability tops the list. We also want to ensure that any interaction, from 
meter reading to billing to repair of storm-damaged electric circuits, is 
fast, reliable and accurate.
     Monthly opinion surveys give our people high ratings for the way they 
handle customer concerns. That approval rating is significantly better than 
the national average, according to a national firm specializing in customer 
satisfaction measurements.

Duquesne Light's electric service is the most reliable in Pennsylvania. That is
especially important when you consider the integral role of electricity in 
improving personal lifestyles and business efficiency.

Objective: 
Deliver quality service and provide superior customer satisfaction in a way 
that differentiates us within the energy services marketplace.

     We're increasing the satisfaction of mid- and large-sized commercial and 
industrial customers by introducing them to electrotechnologies that can 
improve the efficiency of their businesses while reducing their impact on the 
environment.

     For example, in 1993 we worked closely with hospitals and individual 
dental and medical practices to introduce electrotechnologies that safely 
sterilize infectious medical waste. The U.S. Environmental Protection Agency 
estimates that American hospitals each year generate more than 375,000 tons of
soiled bandages and other materials that can cause disease. Through use of 
these electrotechnologies, such material can be disinfected on-site. It then 
can be buried in standard landfills, eliminating higher-priced special 
handling. The

                            KNOWING OUR CUSTOMERS

     Duquesne Light's service territory is relatively compact--approximately 
800 square miles. Yet the company's almost 580,000 customers hold a wide range
of attitudes and preferences concerning their use of electricity and their 
relationship with the provider of that important service. By monitoring and 
analyzing that information, we are finding new and better ways to serve our 
customers.
     
     We've studied various customer surveys and reviewed a wide range of 
typical interactions with customers, as well as usage patterns and payment 
histories. Analysis of this research has enabled us to break down the 
company's service territory into six specific demographic regions--each with 
its own particular characteristics. This enables us to target programs and 
services to customers who can best benefit from them.

     We recently initiated a whole-house surge protection program for 
customers who want added protection from lightning and voltage surges for 
their computers, VCRs, stereos and other sensitive electric equipment. Our 
analysis helps pinpoint areas where this customer service will be most 
valuable. We use information from the analysis in a number of ways, from 
scheduling tree trimming most effectively to placement of cooperative heat 
pump advertising with local heating contractors.

     Another key target audience is the more than 50,000 customers who move 
into new residences each year. Within three days of their arrival, one of our 
representatives delivers a welcome package that includes information about our
services and coupons to local attractions and other money-saving offers. We 
also survey these new customers to learn how we can better serve them. For 
example, we know that many will be making decisions about adding or upgrading 
cooling and heating equipment. Response to the welcome program has been very 
favorable. This good first impression provides a solid customer satisfaction 
foundation to build on.

     All of our customer satisfaction activities recognize that as 
competition increases, the importance of each interaction with each of our 
customers increases.

                                                                             5

process not only reduces disposal costs, but also eliminates any potential 
future liability for untreated infectious waste.
     Application of another innovative electrotechnology will help a local 
university reduce its air-conditioning costs as well as help level the overall
customer peak demand on our system during periods of high temperatures and 
humidity. Thermal storage technology will be showcased at Carnegie Mellon 
University's new research facility, currently under construction at a 
Pittsburgh-area advanced technology business park located on the site of a 
former steel mill. Ice-making to supply air-conditioning will occur during 
off-peak hours. The ice then will be stored for use as needed. This will enable
us to achieve more efficient use of our generating capacity. It's another 
example of the "win-win" solutions we are developing with our customers.

PERFORMANCE IMPROVEMENT

     Previous annual reports have detailed our strong focus on cost control
and performance improvement. Thanks to the initiative and commitment of our
people, we continue to find ways to take costs out of our core business
without sacrificing customer satisfaction, quality performance, safety, or our
environmental commitment. By taking a fresh look at all facets of the way we 
do business, we are discovering additional measures to improve efficiency, 
including re-engineering work processes, taking advantage of new technologies,
and eliminating less important activities.
     Clearly defined performance and budget goals are at the heart of efforts
to improve operations performance. We've also benefitted from changes relating
to crew size, scheduling and increased work force flexibility. New analytical 
technology is helping reduce utility pole replacement costs. "Just-in-time" 
tree-trimming around power lines is improving productivity and system 
reliability. A new, state-of-the-art customer information and billing system 
increases our ability to store a wide range of information that helps us 
provide a quick, comprehensive response when customers call.
     Benchmarking is a valuable source of information to improve operations 
performance, implement process improvements, and reduce costs. We benchmark 
against the best companies in the industry and leaders outside the industry. 
In addition to measuring performance, benchmarking provides opportunities to 
adapt to our operations best practices observed at other companies.
     We want to be recognized as a low-cost producer of electric energy and 
known for excellence in operating performance. Clean, abundant, reasonably 
priced electricity will be a key competitive advantage as the market responds 
to NEPA. DQE already is a major supplier of reliable energy to markets outside
southwestern Pennsylvania. Sales to other utilities totaled 2.8 billion 
kilowatt-hours in 1993.

                              RECYCLABLE REPORT

     The annual report you are reading now is an example of both our 
environmental and our cost-reduction commitments. Printed on recycled paper, 
it also is completely recyclable and was produced at a cost approximately 30 
percent less than last year's report, and approximately 40 percent less than 
the 1991 report.

more than 19 percent of our total sales.  That underscores the importance of 
the wholesale market and our ability to provide it with competitively priced  
power.

ENVIRONMENTAL STEWARDSHIP
    
     Through the years, we have earned a reputation as an environmental leader
within our industry.  Opinion surveys show that environmental quality is a 
paramount concern to utility customers.  Our commitment also provides a 
competitive advantage as other utilities begin to make investments necessary 
to comply with new environmental regulations.

     We pioneered use of wet scrubber systems to help control power plant 
emissions.  Our Pennsylvania coal-fired generating units are among the 
cleanest in the United States.  We pioneered industrial use of fly ash in 
highway construction.  Our Beaver Valley Power Station is an industry leader in
minimizing the volume of low-level radioactive waste.

     In 1993, we formalized our long-standing commitment by developing an 
environmental strategic plan, adopting a corporate environmental charter, and 
establishing an environmental stewardship program.

     In a move we believe is unique to our industry, we have initiated an
environmental training program for all Duquesne Light employees--not just those
involved in power production and distribution.  We want all of our people to be
environmentally conscious, competent and responsible, both on and off the job.

     Our approach to environmental protection goes beyond simply complying with
environmental laws and regulations.  We take pride in carrying our commitment
into the communities we serve. 

     Education is a cornerstone of our stewardship activities.  A wide variety
of programs is helping area youths increase their environmental awareness.  For
example, a cooperative program with the Western Pennsylvania Conservancy, a 
regional conservation group, helps elementary through high school students 
increase their understanding of the environment and their roles in it.

     Another very successful program enables grade school students to learn 
about and plant trees descended from those with historic importance.  We  
received a special commendation from American Forests, the nation's oldest 
non-profit forestry organization, for the results of this program. 

     In a cooperative program with Allegheny County, our people helped collect
approximately 170 tons of old appliances and a wide range of scrap metal--from
hot water tanks and auto parts to metal sinks and paint cans.  The material 
will be recycled for use as feedstock for new steel and metal products.  We 
received commendations from the county and the Pennsylvania Legislature for 
our participation.

     On the job, our people recycled more than 70 tons of paper in 1993, along
with scrap metal from various company operations, oil from transformers, and

wooden pallets. We also increased the use of environmentally compatible 
paints, non-hazardous solvents and parts cleaners, and are working with 
vendors to accept return of boxes, pallets and other packaging/shipping 
materials.

     Our Brunot Island Wildlife Habitat enhancement project continues to 
demonstrate the ability of our power facilities to coexist with nature. Our 
participation in a "rails-to-trails" project along a transmission line 
right-of-way provides another example of this facet of our environmental 
commitment. We recently energized a new 7.3 mile power line near the new 
Pittsburgh International Airport. The line runs along an old railroad 
right-of-way that was developed as a segment of a hiking and biking trail. We 
worked closely with the Montour Trail Council to ensure our line blended in 
with the picturesque setting. The right-of-way was constructed using selective
tree trimming and state-of-the-art erosion and sedimentation control. The 110 
poles that carry the line along the right-of-way are made of a steel that will
oxidize to an earthy brown over time. Through this cooperative effort, local 
residents can enjoy a new recreational facility and better electric service at
the same time.

     We expect the community partnership aspect of our environmental charter 
to gain additional momentum with the inaugural Three Rivers Environmental 
Awards in 1994. The goal of the awards, cosponsored by Duquesne Light and the 
Pennsylvania Environmental Council, is to honor organizations and individuals 
that have demonstrated a commitment to environmental excellence, leadership 
and accomplishment in business, education, community, government, 
communication, or design and development. We hope to encourage the community 
to emulate the achievements of the successful nominees, thereby promoting 
innovative environmental efforts and further enhancing the quality of life.

     Another community outreach initiative planned for 1994 will help small 
and mid-sized businesses learn more about environmental regulations related to
their businesses. With the Southwestern Pennsylvania Industrial Resource 
Center, we are cosponsoring the first of a series of seminars this spring that
will link these important customers with regulatory and legal experts who can 
help them develop cost-effective strategies to meet their environmental 
obligations.

                      CHESTER ENVIRONMENTAL ACQUISITION
- --------------------------------------------------------------------------------
     In 1993, our Duquesne Enterprises subsidiary acquired a controlling 
interest in Chester Environmental, Inc., an engineering and consulting company
that specializes in environmental matters.
     We made this investment because Chester's experience and expertise relate
closely to our core business. We believe the strong demand for environmental 
services will continue to grow in response to new regulations. Investment in 
Chester provides an opportunity to extend our environmental leadership.
     Chester provides water quality, residual solid waste and air quality 
consulting and analytical laboratory services to industrial and government 
clients around the world. Two major contracts were signed in 1993 with steel 
companies in Taiwan and India.

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 plant. The amount represents the estimated cost of both debt and
equity used to finance the construction.

CENTRAL AREA POWER COORDINATION GROUP (CAPCO)
- --------------------------------------------------------------------------------
These companies (Duquesne Light Company, Ohio Edison Company, Pennsylvania Power
Company, The Cleveland Electric Illuminating Company and The Toledo Edison
Company) joined together as CAPCO in 1967 to jointly develop power generation
and transmission facilities.

CONSTRUCTION WORK IN PROGRESS (CWIP)
- --------------------------------------------------------------------------------
This amount represents utility plant 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, Duquesne Light
Company records deferred energy costs to offset differences between actual
energy costs and the level of energy costs currently recovered from customers.

ENERGY COST RATE ADJUSTMENT CLAUSE (ECR)
- --------------------------------------------------------------------------------
Duquesne Light 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.

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 LOAD
- --------------------------------------------------------------------------------
Peak load is the amount of electricity required during periods of highest
demand. 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.) is made up of five members (one a chairman) appointed by
the governor.

REGULATORY ASSET
- --------------------------------------------------------------------------------
Costs that Duquesne Light Company would otherwise have charged to expense are
capitalized or deferred because these costs are currently being recovered or
because it is probable that the PUC will allow recovery of these costs through
rates.
 
                                                                               9

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

CORPORATE STRUCTURE

DQE (the Company) is an energy services holding company. Its principal
subsidiary, Duquesne Light Company (Duquesne), is an electric utility engaged in
the production, transmission, distribution and sale of electric energy. During
1993, Duquesne's operations accounted for most of DQE's total assets, revenues
and income.

While electric utility activities will continue to comprise most of DQE's
business, the Company has taken important steps to develop its other
subsidiaries: Duquesne Enterprises (DE) and Montauk. 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, and investing in real estate. Montauk makes
both short- and long-term investments for the Company, and provides a source of
capital for these other subsidiaries.

RESULTS OF OPERATIONS

OPERATING REVENUES
- --------------------------------------------------------------------------------
Customer operating revenues result from Duquesne's sales of electricity to
ultimate customers and are based on rates authorized by the Pennsylvania Public
Utility Commission (PUC). These rates are designed to recover Duquesne's
operating expenses and investment in utility assets and to provide a return on
the investment. Current and deferred customer revenues resulted from a $232
million rate increase granted in early 1988. The PUC required Duquesne to phase
in this increase during a six-year period. The phase-in plan provided that, with
no impact on total reported customer revenues, rates would increase by
approximately $85 million in April of each year from 1988 through 1991, remain
constant in 1992 and 1993, and decrease by approximately $85 million in April
1994. The phase-in plan also provided for recovery of deferred revenues and
carrying costs on such deferred revenues. The rate increase has been recognized
in operating revenues since March 1988. A regulatory asset has been established
for that portion of revenues yet to be collected from customers, and carrying
charges on this deferred asset have been recognized as a component of other
income in the Statement of Consolidated Income of DQE. Duquesne expects the
remaining balance of this deferred asset to be recovered by April 1994, the end
of the phase-in period.

Short-term sales to other utilities are made at market rates and are included,
along with Duquesne's non-KWH revenues and revenues of DQE's other subsidiaries,
in other operating revenues in the Statement of Consolidated Income of DQE.

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

Revenues from sales of electricity to ultimate customers were favorably impacted
in 1993 and 1991 by warmer than normal summer temperatures. Mild summer weather
in 1992 had the opposite effect on residential and commercial customer sales.

ECR revenues are Duquesne's recovery of  fuel and other energy costs not
otherwise recovered from customers through base rates. The ECR is based on
projected unit costs, is recalculated each year, and is subject to PUC review.
This revenue adjustment includes a credit to

(Millions of KWH)

<PAGE>
 
Duquesne's customers for profits from short-term power sales to other utilities,
as well as an adjustment for any over- or under-collections from customers that
may have occurred in prior years. The 1993 ECR reduced customer costs from 1992
levels and will continue to reduce revenues through the first quarter of 1994 by
a greater amount than in the prior year. From April 1994 through March 1995, the
ECR is expected to reduce revenues by a lesser amount than in the prior year.
This ECR treatment is intended to have no impact on net income.

State tax adjustment surcharge revenues result from the August 1991 tax
increases enacted by the Pennsylvania legislature. Most of these increases were
retroactive to January 1, 1991. The PUC allowed Duquesne to recover these
increases in tax expense by applying, as of August 24, 1991, an adjustment to
customers' bills. Because of the timing of the increase and the rates applied,
Duquesne recovered more state tax adjustment surcharge revenues in 1992 than in
1993 or 1991. This tax recovery is expected, as of April 1994, to become part of
base rates. This tax recovery treatment is intended to have no impact on net
income.

Revenues from other utilities declined in 1993, from the record level of 1992,
because higher system demand and more planned and forced generating station
outages in 1993 decreased Duquesne's capacity available for off-system sales.
The increase, from 1991 to 1992, in these short-term sales to other utilities
resulted from greater availability of transmission and generating capacity,
increased demand by other utilities for energy and Duquesne's marketing efforts.

Other revenues include revenues of DE and Montauk, as well as Duquesne's rental
income and billings to other companies in the CAPCO group. Revenues of DE
increased approximately $23 million in 1993; the increase was partially due to
the acquisition of a controlling interest in Chester Environmental, Inc. (See
Note A to the consolidated financial statements.) and higher sales to the
Pittsburgh International Airport. Primarily as a result of increased leasing
activities and other tax advantaged investments, Montauk revenues increased
approximately $8 million.

OPERATING EXPENSES
- --------------------------------------------------------------------------------
Yearly fluctuations in fuel and purchased power expense result from changes in
the cost of fuel, the mix between coal and nuclear generation, the total KWHs
generated and the effects of deferred energy costs. In 1993, the impact of the
ECR on deferred energy costs decreased fuel expense, in comparison to that for
1992. Also contributing to the decline in fuel expense was a 6 percent decrease
in generation that was primarily due to more planned and forced generating plant
outages in 1993. Fuel expense for 1992 was greater than that for 1991 because of
increased generation of electricity for sale to other utilities; however, the
greater fuel expense was partially offset in 1992 by lower coal and nuclear fuel
costs per KWH. In 1994, nuclear fuel costs are expected to continue to decline,
and coal costs are expected to remain near the 1993 level.

Other operating expenses were higher in 1993 than 1992. In 1993, Duquesne
finalized plans to sublease the majority of its office space at corporate
headquarters; relocation of its principal business offices is anticipated in
1994. A charge of approximately $13 million was recorded as an operating expense
to reflect the shortfall in anticipated sublease revenues from the rental
payments related to space leased through January 2003, the date the leasing
arrangements expire. Additionally, operating expenses at DE increased
approximately $17 million in 1993 as a reflection of the acquisition of a
controlling interest in Chester Environmental, Inc. (See Note A to the
consolidated financial statements.) Included in 1991 operating expenses was an
increase, caused by the deterioration of Duquesne's past due customer accounts
and increased collection costs, of $11.9 million in the allowance for
uncollectible accounts receivable.

Maintenance expense incurred for scheduled refueling outages at Duquesne's
nuclear units is deferred and amortized over the period between scheduled
outages. During 1993, amortization of deferred nuclear refueling outage expense
increased approximately $3.5 million over the 1992 level. 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 station outages.
Prior to 1993, maintenance costs incurred for scheduled major outages at fossil
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 new method was adopted to match more accurately
the maintenance costs with the revenue produced during the periods between
scheduled major fossil outages.

Depreciation and amortization expense increased in 1993 by comparison with that
for 1992 and 1991. The increase was primarily a result of an increase in
depreciable property.

Taxes other than income taxes decreased in 1993, primarily as a result of a
favorable resolution of property tax assessments. In 1993, Duquesne recorded, on
the basis of this revised assessment, the expected refunds of these overpayments
in prior years. By comparison with those for 1991, taxes other than income taxes
decreased in 1992 as the result of favorable resolution of capital stock tax,
gross receipts tax and sales tax matters.

Income taxes increased in 1993 as a result of an increase in taxable income and
a 1 percent increase in the corporate federal income tax rate.

OTHER INCOME AND DEDUCTIONS
- --------------------------------------------------------------------------------
During the fourth quarter of 1993, Duquesne recognized a charge to other income
of approximately $15.2 million for its investment in the abandoned General
Public Utilities (GPU) transmission line project. On December 8, 1993, the New
Jersey Board of Regulatory Commissioners (BRC) denied a request by GPU's
subsidiary Jersey Central Power and Light Company for approval of long-term
power purchase and operating agreements that were originally signed in 1990 by
GPU and Duquesne and further amended in 1993. The BRC rejected an administrative
law judge's recommended decision that the project be approved and, within hours
of the BRC decision, GPU terminated its participation in the project. In view of
GPU's decision, Duquesne also terminated its participation in the project and
the PUC transmission line siting proceeding.

Other income also decreased in 1993, in comparison with that for 1992, as a
result of a decrease of approximately $13 million in carrying charges on
deferred revenues. During 1993, the deferred revenue balance upon which carrying
charges are earned declined in comparison with that for 1992 and since April
1993, Duquesne has not recorded additional carrying charges on deferred
revenues. (See the discussion of the phase-in plan under the section on
operating revenues.)

Income taxes related to other income decreased $15 million in 1993, in
comparison with those for 1992, because of a favorable settlement (related to
Duquesne's 1988 tax return and the consolidated 1989 tax return) with the United
States Internal Revenue Service. The remaining decrease in 1993 was caused by
lower non-operating income.

Other income for 1992 increased, in comparison with that for 1991, primarily as
the result of an increase of $3.5 million in interest income and a decrease of
$3.7 million in fees related to Duquesne's sale of receivables. Other income for
1991 included a $5.3 million regulatory accounting reclassification that
decreased other income, reduced depreciation expense and had no impact on net
income.

INTEREST AND OTHER CHARGES
- --------------------------------------------------------------------------------
Duquesne achieved reductions in interest and other charges in 1993 and 1992
through refinancing first mortgage bonds and through obtaining lower average
short-term rates on certain tax exempt pollution control notes. Duquesne also
retired $24.2 million of preferred and preference stock during 1992. Interest
expense and dividends on preferred and preference stock declined to $121 million
in 1993 from $135 million in 1992 and $145 million in 1991. Interest expense and
preferred stock dividends are expected to decline in 1994 by approximately $9
million from the 1993 level.

CAPITAL RESOURCES AND LIQUIDITY

CONSTRUCTION
- --------------------------------------------------------------------------------
During 1993, Duquesne spent approximately $100 million for construction.
Duquesne expended these amounts to improve and expand its production,
transmission and distribution systems. Duquesne estimates that it will spend
approximately $110 million for construction in 1994. Construction expenditures
are estimated to be $70 million in 1995 and $80 million in 1996. These amounts
exclude AFC, nuclear fuel and expenditures for possible early replacement of
steam generators at the Beaver Valley Power Station. (See Note K to the
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.

INVESTING
- --------------------------------------------------------------------------------
Through DE and Montauk, DQE's investments are focused in four principal areas:
energy, environmental services, leasing and tax-advantaged investments. After
achieving a modest profit of $.02 per DQE share in 1992, these subsidiaries
contributed $.13 per share to the Company's 1993 earnings. During 1993, the
level of investing activities increased in comparison with that for 1992. On
August 17, 1993, DE acquired a controlling interest in Chester Environmental,
Inc. for approximately $12 million. Chester provides total environmental
consulting and engineering services to a wide range of clients. During 1993, DE
also made real estate investments totaling approximately $22 million. Previous
DE investments included Allegheny Development Corporation (which provides all
energy services for the Pittsburgh International Airport) and International
Power Machines (which manufactures products and systems designed to provide non-
interruptible electric power). During 1993, Montauk invested approximately $44
million in leases and other tax-advantaged investments. The lease rentals in
these transactions are guaranteed by the lessee's parents or affiliates.

FINANCING
- --------------------------------------------------------------------------------
The Company plans to meet its current obligations and debt maturities through
1998 with funds generated from operations and through new financings. At
December 31, 1993, the Company was in compliance with all of its debt covenants.

Duquesne continues to reduce capital costs by refinancing and retiring
securities. During 1993, Duquesne issued $695 million of first collateral trust
bonds with maturities ranging from the year 1996 through the year 2025 and with
an average interest rate of 6.58 percent. The proceeds of these sales were used
to redeem $713.7 million of first mortgage bonds with an average interest rate
of 8.16 percent.

In June 1993, Duquesne participated in the issuance of $25 million of Beaver
County Industrial Development Authority Pollution Control Revenue Bonds. In
August 1993, Duquesne participated in the issuance of $20.5 million of Ohio Air
Quality Development Authority Pollution Control Revenue Refunding Bonds to
refund a like amount of pollution control obligations.

In August 1993, Montauk entered into a revolving credit agreement with a group
of banks. Under this agreement, Montauk can borrow, on a revolving basis, up to
$50 million for working capital and other general corporate purposes. If the
agreement is not extended at the end of its 364-day commitment period, Montauk
can convert any outstanding borrowings into a two-year, amortizing term loan. At
December 31, 1993, Montauk had borrowed $25 million under this agreement.

On January 14, 1994, Duquesne redeemed all of its outstanding shares of $2.10
preference stock and $7.50 preference stock for approximately $38 million.

In 1992, Duquesne refinanced $312.9 million and retired $82.1 million of long-
term debt.

Duquesne established, as of January 1, 1992, an Employee Stock Ownership Plan
(ESOP) to fund a match of a portion of employee contributions for a 401(k) plan.
Duquesne may purchase shares of DQE common stock from DQE or on the open market
to satisfy the exchange feature of its Preference Stock, Plan Series A. The
Company expects the ESOP to have minimal dilutive impact on earnings per share.

<PAGE>
 
SALE OF ACCOUNTS RECEIVABLE
- --------------------------------------------------------------------------------
In 1989, Duquesne and an unaffiliated corporation entered into an agreement that
entitled Duquesne to sell and the corporation to purchase, on an ongoing basis,
up to $100 million of accounts receivable. At December 31, 1993, Duquesne had
sold $9 million of receivables. The accounts receivable sales agreement, which
expires in June 1994, is one of many sources of funds available to Duquesne.
Duquesne is currently evaluating whether to seek an extension of the agreement.

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,
1993, the amount of nuclear fuel financed by Duquesne under this arrangement
totaled approximately $65 million. Duquesne plans to continue leasing nuclear
fuel to fulfill its requirements at least through 1995, the remaining term of
the current leasing arrangement.

DIVIDENDS
- --------------------------------------------------------------------------------
The Company or its predecessor, Duquesne, has continuously paid dividends on
common stock since 1953. The quarterly dividends paid have increased by an
average annual rate of 5.9 percent over the past five years, even though the
Company has maintained a more conservative payout ratio than the 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 for funds and the availability of those generated
from operations will be affected by the level of economic activity in Duquesne's
service area and by legislation, rate-related proceedings, competition and
environmental and other matters experienced by the Company and 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 stockholders' 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, 1993.

OUTLOOK

COMPETITION
- --------------------------------------------------------------------------------
Duquesne, like the electric utility industry in general, faces increasing
competition. The Company 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. At the current time, the Company has not made any
investment, and has no plans to make any investment, in EWGs. 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 to
facilitate sales to other utilities. The amendments would permit the Federal
Energy Regulatory Commission (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 FERC may not, however,
issue any order that would unreasonably impair the continuing reliability of
affected electric systems. Finally, brokers and marketers, without owning or
operating any generation or transmission facilities, have also entered into the
business of buying and selling electric capacity and energy.

Industrial and large commercial customers may have the ability 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.

In addition, increased competition may also result from the 1990 Amendments to
the Clean Air Act. Such amendments exempt from sulfur dioxide (SO2) and oxides
of nitrogen (NOX) control requirements existing units with less than 25 MWs of
generating capability, and new or existing co-generation units supplying less
than one-third of their electric output and less than 25 MWs for commercial
sale.

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's capitalized costs and net investment in the plants at
December 31, 1993 totaled $130 million. (See Note L to the consolidated
financial statements.)

Duquesne expects to recover its net investment in these plants through future
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 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 meeting market opportunities to supply long term bulk
power. Recent legislation may permit wider transmission access to these long
term bulk power markets. 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.

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
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.
Emission allowances are permits to emit one ton of SO2 for one year. 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 reductions of SO2 and NOX by 1995 and
additional reductions by the year 2000. Duquesne continues to work with the
operators of its jointly owned
 
                                                                              15

stations to implement cost-effective compliance strategies to meet these
requirements. Duquesne's plans for meeting the 1995 SO2 compliance
requirements include increasing the use of scrubbed capacity, switching to fuel
with a lower sulfur content and purchasing emission allowances. NOX reductions
under Title IV are required by 1995 at only the Cheswick station; work to
achieve the reductions was completed in 1993. The ozone attainment provisions of
Title I of the Clean Air Act Amendments will require NOX reductions by 1995 at
Duquesne's Elrama plant and at the jointly owned Mansfield plant. Duquesne plans
to achieve such reductions with low NOX burner technology. The estimated
capital costs to achieve 1995 compliance standards are approximately $30
million, of which approximately $15 million has already been spent. 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. The Company currently estimates that additional capital costs to
comply with environmental requirements from 1995 through the year 2000 will be
approximately $20 million. This estimate is subject to the finalization of
federal and state regulations.

Duquesne is closely monitoring other potential air quality programs and air
emission control requirements that could be imposed in the future. These areas
include additional NOX control requirements that could be imposed on fossil
fuel plants by the Ozone Transport Commission, more stringent ambient air
quality and emission standards for SO2 and particulates, or CO2 control
measures. 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 of these programs at this time.

In July 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 $10 million through 1995. The
expected additional capital cost of compliance from 1995 through 2000 is
approximately $25 million; this estimate is subject to the results of ground
water assessments and DER final approval of compliance plans.

Duquesne operates the scrubbed Elrama plant and converts the scrubber slurry to
a fixated pozolonic material. This material is placed at an off-site disposal
area having approximately six years of remaining capacity. Additionally,
Duquesne owns 17 percent of the scrubbed Mansfield plant, which is operated by
Pennsylvania Power. This plant pumps a similar slurry to an off-site impoundment
where the slurry is treated by using a Calcilox fixation process. The site has
at least 14 years of remaining capacity. Both plants have limited temporary on-
site storage for flue gas desulfurization material and no permanent on-site
disposal capacity. While there is no imminent shortage of disposal capacity,
Duquesne continues to monitor this situation and to plan for future disposal.
The siting of future disposal facilities will be facilitated by the 1993 EPA
determination that coal combustion waste products are not hazardous waste and
are therefore exempt from the Hazardous Waste Regulations.

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, the CAPCO companies have entered into
contracts 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 1996, 2010, and 2009,
respectively. Duquesne is currently increasing the storage capacity at Beaver
Valley 1 by equipping the spent fuel pool with high density fuel storage racks.
Duquesne anticipates that such action will increase the spent fuel storage
capacity at Beaver Valley 1 to provide for sufficient storage through 2014.

OTHER SUBSIDIARY OPERATIONS
- --------------------------------------------------------------------------------
The continued growth of DE and Montauk is expected to play an increasing role in
DQE's overall corporate strategy and future earnings.

RETIREMENT PLAN MEASUREMENT ASSUMPTIONS
- --------------------------------------------------------------------------------
The Company reduced the discount rate used to determine the projected benefit
obligation on the Company's retirement plans at December 31, 1993, to 7 percent.
The assumed change in future compensation levels was also decreased by 0.5
percent 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 I to the consolidated financial
statements. The resulting increase in related expenses for subsequent years is
not expected to be material.

GENERAL ELECTRIC SETTLEMENT
- --------------------------------------------------------------------------------
In January 1994, the CAPCO companies reached a settlement in connection with a
1991 lawsuit against General Electric Company (GE) regarding the Perry Plant.
The settlement provides for cash payments to the CAPCO companies and discounts
on future purchases from GE. This settlement will not materially affect the
Company's results of operations in future years.

OTHER
- --------------------------------------------------------------------------------
Duquesne's utility operations are subject to regulation by the PUC and the FERC.
This regulation is designed to provide for the recovery of operating costs and
investment and the opportunity to earn a fair return on funds invested in the
utility business. The regulatory process imposes a time lag during which
increases in operating expenses, capital costs or construction costs may not be
recovered.

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

TO THE DIRECTORS AND STOCKHOLDERS OF DQE:

We have audited the accompanying consolidated balance sheets of DQE and its
subsidiaries as of December 31, 1993 and 1992, and the related consolidated
statements of income, common stockholders' equity, and cash flows for each of
the three years in the period ended December 31, 1993. 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, 1993 and 1992, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 1993 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 1993, the Audit Committee recommended to
the Board of Directors, the selection, subject to shareholder approval, 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 ACCOUNTING POLICIES
 
CONSOLIDATION
- --------------------------------------------------------------------------------
The consolidated financial statements include the accounts of DQE (the Company)
and its subsidiaries. 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 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 consolidated financial statements reflect the rate-making practices of
Duquesne Light Company (Duquesne) and, as a result, contain regulatory assets
and liabilities as deferred charges and credits in accordance with Statement of
Financial Accounting Standards Number 71, Accounting for the Effects of Certain
Types of Regulation (SFAS No. 71). Duquesne's accounting practices conform to
the Uniform System of Accounts prescribed by the Federal Energy Regulatory
Commission (FERC)and the requirements of the Pennsylvania Public Utility
Commission (PUC). The Company is also subject to the accounting and reporting
requirements of the Securities and Exchange Commission (SEC).

PROPERTY, PLANT AND EQUIPMENT
- --------------------------------------------------------------------------------
The asset values of 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 9.6
percent in 1993, 10.3 percent in 1992, and 9.6 percent in 1991.

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 a first mortgage lien,
and substantially all of Duquesne's electric properties are subject to junior
liens.

DEPRECIATION
- --------------------------------------------------------------------------------
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.

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 each nuclear plant at
the end of its life, a date that currently coincides with the expiration of each
plant's operating license. (See Note L.) The total estimated decommissioning
costs, including removal and decontamination costs, being recovered in rates are
$70 million for Beaver Valley Unit 1, $20 million for Beaver Valley Unit 2, and
$38 million for Perry Unit 1. These amounts were based upon the most recent
studies available at the time of Duquesne's last rate case.

Since the time of Duquesne's last rate case, site specific studies have been
performed to update the estimated decommissioning costs, in current dollars, for
each of its nuclear generating units. In 1992, Duquesne's share of the estimated
decommissioning costs for Beaver Valley Unit 2 was revised to $35 million.
Duquesne's share of decommissioning costs, which is based on preliminary site
specific studies to be finalized early in 1994, is estimated to increase to $134
million for Beaver Valley Unit 1 and to $71 million for Perry.

During 1994, it is Duquesne's intention to increase 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.

Duquesne records decommissioning costs under the category of depreciation
expense and accrues a liability, equal to that amount, for nuclear
decommissioning expense. Such nuclear decommissioning funds are deposited in
external, segregated trust accounts. Trust fund earnings increase the fund
balance and the recorded liability. The aggregate trust fund balances at the end
of 1993 totaled $18.1 million. On the Company's consolidated balance sheet, the
decommissioning trusts have been reflected in other property and investments,
and the related liability has been recorded as other deferred credits.

MAINTENANCE
- --------------------------------------------------------------------------------
Maintenance expense incurred for scheduled refueling outages at Duquesne's
nuclear units is deferred and amortized over the period between scheduled
outages. 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 (approximately $5.4 million, net of income taxes of
approximately $3.9 million) of the change on prior years was included in 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.

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. Deferred revenues
are associated with the Company's 1987 rate case. (See Note J.)

INCOME TAXES
- --------------------------------------------------------------------------------
On January 1, 1993, the Company adopted Statement of Financial Accounting
Standards Number 109 (SFAS No. 109). Implementation of SFAS No. 109 involved a
change in accounting principles. 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. As a
utility, Duquesne recognizes uncollected deferred income taxes for these
deferred tax liabilities that are expected to be recovered from customers
through rates. The adoption of SFAS No. 109 on January 1, 1993, resulted in a
$700 million increase in deferred tax liabilities and the recognition of $550
million in net regulatory assets. Prior to the adoption of SFAS No. 109,
Duquesne recorded certain costs in electric plant in service net of taxes.
Because SFAS No. 109 eliminates this "net of tax" accounting, the adoption of
SFAS No. 109 also resulted in an increase in plant assets of $150 million.

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.

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. 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.

Duquesne defers fuel and other energy expenses for recovery through the ECR in
subsequent years. The deferrals reflect the difference between the amount that
Duquesne is currently collecting from customers and its actual fuel costs. The
Pennsylvania Public Utility Commission (PUC) annually reviews Duquesne's fuel
costs for the fiscal year April through March, compares them to previously
projected fuel costs and adjusts the ECR for over- or under-recoveries and for
two PUC-established coal cost standards. (See Note J.)

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, 1993 and 1992, $10.1 million and $18.9 million were payable to customers and
shown as deferred energy costs.

CASH FLOWS
- --------------------------------------------------------------------------------
For the purpose of the statement of cash flows, the Company considers all highly
liquid investments maturing in three or fewer months to be cash equivalents.

RECLASSIFICATIONS
- --------------------------------------------------------------------------------
The 1992 and 1991 financial statements have been reclassified to conform with
accounting presentations adopted during 1993.

B. EXTRAORDINARY PROPERTY LOSS

In 1984, companies comprising the CAPCO group agreed to minimize construction
work and cash expenditures on Perry Unit 2 until several alternatives, including
resumption of construction or cancellation of the unit, were evaluated. Duquesne
abandoned its interest in the unit in 1986 and subsequently disposed of its
interest in 1992.

In 1987, 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 $39.4 million at
December 31, 1993) of its investment in the unit.

                                                                            25

C.  CAPITALIZATION

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 1993 was increased to $.42 per share. This annualized dividend of $1.68 per
share was increased from $1.60 per share in 1992. The annualized dividend per
share was $1.52 in 1991 and $1.44 in 1990.

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 stockholders' 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 stockholders. No part of the retained earnings of DQE or any of
its subsidiaries was restricted at December 31, 1993.

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, 1993, 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, 1993, Duquesne had
made all dividend payments.

Outstanding preferred and preference stock is generally callable, on notice of
not less than 30 days, at stated prices (See table on page 27.) plus accrued
dividends. On January 14, 1994, Duquesne called for redemption of 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 I.) Duquesne issued and sold 845,070 shares
of redeemable 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, 1993, $27.1 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 will be used to repay
the ESOP note. During 1993, Duquesne made cash

26
<PAGE>
 
contributions of approximately $2.1 million, the difference between the ESOP
debt service and the amount of dividends on ESOP shares (approximately $2.3
million). 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. In 1993, the Company
recognized $1.7 million of compensation expense related to the 401(k) plan.

LONG-TERM DEBT
- --------------------------------------------------------------------------------
At December 31, 1993, Duquesne had $1.433 billion of outstanding debt
securities; these consisted of $960 million of first collateral trust bonds, $49
million of first mortgage bonds, $418 million of pollution control notes and $6
million of debentures.

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 and $265 million, and having
average interest rates of 6.58 percent and 8.04 percent, were issued in 1993 and
1992.

Since 1985, the Company has reacquired $1.561 billion of first mortgage bonds.
The difference between the purchase prices and the net carrying amounts of these
bonds has been included in the consolidated balance sheet as unamortized loss on
reacquired debt. At December 31, 1993, the balance of unamortized loss on
reacquired debt was $95.3 million.

                                                                              27

At December 31, 1993 and 1992, the Company was in compliance with all of its
debt covenants.

At December 31, 1993, sinking fund requirements and maturities of long-term debt
outstanding for the next five years were: $11.8 million and $.1 million in 1994;
$11.4 million and $49.6 million in 1995; $11.2 million and $50.1 million in
1996; $10.8 million and $50.0 million in 1997; and $10.1 million and $75.0
million in 1998.

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 1993, annual sinking fund
requirements of $.5 million were satisfied by cash and $4.8 million by
certification of property additions.

Total interest costs incurred were $118.1 million in 1993, $133.9 million in
1992 and $147.2 million in 1991. Of these amounts, which included AFC, $2.0
million in 1993, $4.7 million in 1992 and $9.3 million in 1991 were capitalized.
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' $188 million equity interest in the unit and certain tax benefits. 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.

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 June 1993, $25 million of pollution control notes were issued; the
proceeds were used to reimburse Duquesne for pollution control expenditures
related to the Beaver Valley plant. In August 1993, pollution control notes
totaling $20.5 million were refinanced at lower interest rates.

At December 31, 1993, the fair value of the Company's long-term debt and
redeemable preference stock approximated the carrying value. The fair value of
the Company's long-term debt and redeemable preference stock was estimated on
the basis of (a) quoted market prices for the same or similar issues or (b)
current rates offered to the Company for debt of the same remaining maturities.

D.  RECEIVABLES

An arrangement between Duquesne and an unaffiliated corporation entitles
Duquesne to sell, and the corporation to purchase, up to $100 million of
Duquesne's accounts receivable. At December 31, 1993 and 1992, Duquesne had sold
$7.1 million and $66.3 million of electric customer accounts receivable and $1.9
million and $9.7 million of CAPCO receivables, respectively, to the unaffiliated
corporation. The sales agreement includes a limited recourse obligation under
which Duquesne could be required to repurchase certain of the receivables. The
maximum amount of Duquesne's contingent liability was $2.8 million at December
31, 1993.

Other receivables in the Consolidated Balance Sheet of DQE include receivables
of DQE's other subsidiaries. These receivables amounted to $31.8 million and
$1.0 million at December 31, 1993 and 1992, respectively.

E.  LEASES

Duquesne leases nuclear fuel, a portion of a nuclear generating plant, 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 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. In December 1992, Duquesne participated
in the refinancing of

30
<PAGE>
 
collateralized lease bonds 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 rent payment to the lessors. This
amount was deferred and is being amortized over the remaining lease term. At
December 31, 1993, the balance was approximately $34.9 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.

Future payments due to the Company, as of December 31, 1993, under subleases of
its corporate headquarters space are approximately $1.7 million in 1994, $3.4
million in 1995 and $24.9 million thereafter.

The Company, through its Montauk subsidiary, 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 $143.5 million at December 31, 1993.

F.  INCOME TAXES

The annual federal corporate income tax returns have been audited by the United
States 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 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
principles. The cumulative effect of $8 million on prior years was reported in
1993 as an increase in net income. The SFAS No. 109 impact to 1993 income before
cumulative effect of changes in accounting principles is immaterial.

At December 31, 1993, the accumulated deferred income taxes of the Company
totaled $1.169 billion. As discussed in Note A, this includes the deferred tax
liability for the book and tax bases differences associated with (i) electric
plant in service of $855 million; (ii) uncollected deferred income taxes of $199
million; and (iii) unamortized loss on reacquired debt of $40.9 million. The
Company also nets against this liability balance the deferred tax assets
associated with (i) investment tax credits unamortized of $45.3 million and (ii)
the gain on the sale and leaseback of Beaver Valley Unit 2 of $67.1 million. The
Company expects to realize these deferred tax assets.

I.  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 $9.8 million for 1993, $11.4 million for 1992 and $11.2 million for 1991.

RETIREMENT SAVINGS PLAN AND OTHER BENEFIT OPTIONS
- --------------------------------------------------------------------------------
The Company sponsors separate 401(k) retirement plans for its union-represented
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)
 
34
<PAGE>
 
account up to a maximum of 6 percent of his or her eligible salary. The Company
match consists of a $.25 base match and an additional $.25 incentive match, if
targets approved by the Company's board of directors are met. The 1993 incentive
target was met. The Company is funding its matching contributions with
contributions to an ESOP established in December 1991. (See Note C.)

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, 1993, approximately 2.9 million of these shares
were available for future grants.

As of December 31, 1993, 1992 and 1991, respectively, active grants totaled
1,204,000; 848,000; and 1,278,000 shares. Exercise prices of these options
ranged from $12.3125 to $34.1875 at December 31, 1993 and from $12.3125 to
$28.75 at December 31, 1992 and 1991. Expiration dates of these grants ranged
from 1997 to 2003 at December 31, 1993; from 1997 to 2002 at December 31, 1992;
and from 1997 to 2001 at December 31, 1991. As of December 31, 1993, 1992 and
1991, respectively, stock appreciation rights (SARs) had been granted in
connection with 800,000; 623,000; and 822,000 of the options outstanding. During
1993, 103,000 SARs were exercised; 16,000 options were exercised at prices
ranging from $12.3125 to $28.375; and 52,000 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. During 1991, 229,000 SARs
were exercised; 11,000 options were exercised at $12.3125; and 48,000 options
lapsed. Of the active grants at December 31, 1993, 1992 and 1991, respectively,
578,000; 232,000; and 541,000 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 Number 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.

In prior years, the Company recognized the cost of providing postretirement
benefits by expensing the contributions as they were made. Costs recognized
under this method in 1992 approximated $1.2 million. The new accrual method
increased the cost recognized for providing postretirement benefits to
approximately $6.0 million.

For measurement purposes, a 10.5 percent increase in the cost of covered health
care benefits was assumed as of January 1, 1993. This rate is assumed to
decrease to 5.5 percent by 1999 and remain at that level thereafter. The health
care cost trend rate assumption has a significant effect on the amounts
reported. A 1 percent increase in the health care cost trend rate would increase
the accumulated postretirement benefit obligation by $4.0 million at January 1,
1994, and the net annual cost by $.6 million for the year. The weighted average
discount rate used in determining the accumulated postretirement benefit
obligation was 7 percent.

J.  RATE MATTERS

1987 RATE CASE
- --------------------------------------------------------------------------------
In March 1988, the PUC adopted a rate order that increased Duquesne's annual
revenues by $232 million. This increase is being phased in from April 1, 1988
through April 1, 1994. Deficiencies which resulted from the phase-in plan in
current revenues from customers have been included in the consolidated income
statement as deferred revenues. Deferred revenues have been recorded on the
balance sheet as a deferred asset for future recovery. As customers are billed
for deficiencies related to prior periods, this deferred asset is reduced. As
designed, the phase-in plan provides for carrying charges (at the after-tax AFC
rate) on revenues deferred for future recovery. Since April 1993, Duquesne has
not recorded additional carrying charges on the deferred revenue balance.
Duquesne had recovered previously deferred revenues and carrying charges of
$285.9 million as of December 31, 1993. Phase-in plan deferrals of $28.6 million
remained unrecovered as of that date. Duquesne expects to recover this remaining
unrecovered balance by the end of the phase-in period.

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

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, 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. At
December 31, 1993, 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.

36
<PAGE>
 
Duquesne believes that these deferred costs are recoverable. In 1990, another
Pennsylvania utility was permitted recovery, with no return on the unamortized
balance, of similar costs over a 10-year period.

DEFERRED ENERGY COSTS
- --------------------------------------------------------------------------------
Duquesne defers fuel and other energy costs for recovery in subsequent years
through the ECR. The deferrals reflect the difference between the amount that
Duquesne is currently collecting from customers and its actual fuel costs. The
PUC reviews Duquesne's fuel costs annually, for the fiscal year April through
March, against the previously projected fuel costs and adjusts the ECR for over-
or under-recoveries and for two PUC-established coal cost caps.

The PUC has established market price coal cost standards for all Pennsylvania
utilities that have interests in mines that supply coal to their generating
stations. Duquesne is subject to two such 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 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 $7.4 million and the
unrecovered cost of coal used throughout the system amounted to $8.8 million at
December 31, 1993. Duquesne believes that all deferred coal costs will be
recovered.

WARWICK MINE COSTS
- --------------------------------------------------------------------------------
The 1990 joint petition for settlement (See preceeding section on deferred
energy 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; the sulfur content averages in the mid-range at
1.7 percent - 1.9 percent sulfur content. More than 90 percent of the coal mined
at Warwick currently is used by Duquesne. Duquesne receives a royalty on sales
of coal in the open market. The Warwick Mine currently supplies less than one-
fifth of the coal used in the production of electricity at the plants operated
by Duquesne and those owned by CAPCO.

Costs at the Warwick Mine and Duquesne's investment in the mine are expected to
be recovered through the ECR. Recovery is subject to the system-wide coal cost
standard. Duquesne also has an opportunity to earn, through the ECR, a return on
its investment in the mine during the period, including extensions, of the
system-wide coal cost standard. At December 31, 1993, Duquesne's net investment
in the mine was $24.5 million. The estimated current liability for mine closing
(including final site reclamation, mine water treatment and certain labor
liabilities) is $33.0 million and Duquesne has collected approximately $8.9
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's capitalized costs and net investment in the plants at
December 31, 1993 totaled $130 million. (See Note L.)

On December 8, 1993, the New Jersey Board of Regulatory Commissioners (BRC)
denied a request by General Public Utilities' (GPU) subsidiary Jersey Central
Power and Light Company for approval of the long-term power purchase and
operating agreements, originally signed in

                                                                              37
<PAGE>
 
1990, between GPU and Duquesne and further amended earlier in 1993. The BRC
rejected an administrative law judge's recommended decision that the project be
approved and, within hours of the BRC decision, GPU terminated its participation
in the project. In view of GPU's decision not to proceed, Duquesne terminated
its participation in the project and in the PUC transmission line siting
proceeding. During the fourth quarter of 1993, Duquesne recognized a charge of
approximately $15.2 million for its investment in this abandoned GPU
transmission line project.

Duquesne expects to recover its net investment in these plants through future
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 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 meeting market opportunities to supply long term bulk
power. Recent legislation may permit wider transmission access to these long
term bulk power markets. 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.

K.  COMMITMENTS AND CONTINGENCIES

CONSTRUCTION
- --------------------------------------------------------------------------------
Duquesne estimates that it will spend approximately $110 million on construction
during 1994. Construction expenditures are estimated to be $70 million in 1995
and $80 million in 1996. These amounts exclude AFC, nuclear fuel and
expenditures for possible early replacement of steam generators at the Beaver
Valley Station.

WESTINGHOUSE LAWSUIT
- --------------------------------------------------------------------------------
The CAPCO companies are owners of various portions of Beaver Valley Units 1 and
2. In 1991, the CAPCO companies 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. The Company is seeking monetary and
corrective relief. 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. If the corrosion and cracking
continue, replacement of the steam generators could be required prior to the
ends of their 40-year design lives. The Company is continuing to conduct a
corrective maintenance program and to explore longer term options, including
replacement of the steam generators. While the Company has no current plans to
replace the steam generators and has not yet completed a detailed, site-specific
study, replacement cost per unit is estimated to be between $100 million and
$150 million. (Other utilities with similar units have replaced steam generators
at costs in this range.) The Company cannot predict the outcome of this matter;
however, the Company does not believe that resolution will have a materially
adverse effect on the Company's 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 is held by the other CAPCO companies. Duquesne operates both units
on behalf of the CAPCO companies.

NUCLEAR INSURANCE
- --------------------------------------------------------------------------------
The CAPCO companies maintain the maximum available nuclear insurance for the
$5.9 billion total investment in Beaver Valley Units 1 and 2. The insurance
program provides $2.7 billion for property damage, decommissioning, and
decontamination liabilities. The CAPCO companies have similar property insurance
for the $5.4 billion total investment in Perry Unit 1.

38
<PAGE>
 
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 of as much as
$6.5 million for up to seven years.

The Price-Anderson Amendments to the Atomic Energy Act limit public liability
from a single incident at a nuclear plant to $9.4 billion. Duquesne has
purchased $200 million of insurance, the maximum amount available, which
provides the first level of financial protection. Additional protection of $8.8
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 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
premium tax of  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.

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 the Company's 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 67 percent of
such estimate per week for the following 104 weeks. The amount and duration of
actual extra expense could substantially exceed insurance coverage.

GUARANTEES
- --------------------------------------------------------------------------------
Duquesne and the other CAPCO companies have guaranteed certain debt and lease
obligations related to a coal supply contract for the Bruce Mansfield plant. At
December 31, 1993, Duquesne's share of these guarantees was $35.2 million. The
prices paid for the coal by the CAPCO companies under this contract are expected
to be sufficient to meet debt and lease obligations to be satisfied in the year
2000. (See Note J.) The minimum future payments to be made by Duquesne solely in
relation to these obligations are $6.9 million in 1994, $6.6 million in 1995,
$6.3 million in 1996, $5.9 million in 1997, $5.6 million in 1998, $5.3 million
in 1999 and $4.1 million in 2000. Duquesne's total payments for coal purchased
under the contract were $26.5 million in 1993, $25.2 million in 1992 and $32.6
million in 1991.

RESIDUAL WASTE MANAGEMENT REGULATIONS
- --------------------------------------------------------------------------------
In July 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 for these regulations. Capital compliance costs
are estimated, on the basis of currently available information, at $10 million
through 1995. Through the year 2000, the expected additional capital cost of
compliance, which is subject to the results of ground water assessments and DER
final approval of compliance plans, is approximately $25 million.

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.

L.  GENERATING UNITS

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.

                                                                              39
