(1)  The amount of any bonus compensation is determined annually 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
     each year are the awards earned in those years but established and paid or
     deferred in the subsequent years.
<PAGE>
 
(2)  Amounts of Other Annual Compensation are connected to the funding of non-
     qualified pension benefit accruals and/or compensatory tax payments on
     restricted stock.  Amounts of Other Annual Compensation for Mr. Roque
     represent reimbursement for moving expenses, including sale of residence
     and income taxes.  Amounts of All Other Compensation shown are Company
     match contributions during 1995, 1996, and 1997 under the Duquesne Light
     Company 401(k) Retirement Savings Plan for Management Employees.

(3)  The awards listed are the only restricted stock holdings of the named
     officers.

(4)  Includes total number of stock options granted during the fiscal year, with
     or without tandem SARs and stock-for-stock (reload) options on option
     exercises, as applicable, whether vested or not.  See table titled
     Option/SAR Grants in Last Fiscal Year.  The stock options are subject to
     vesting (exercisability) based on Company and individual performance and
     achievement of specified goals and objectives.

(5)  In 1996, Messrs. Marshall and Cross were each granted 5,000 shares of
     restricted stock subject to the achievement of performance goals over a
     three-year period.  In August of 1997, Messrs. Marshall and Cross were each
     awarded 2,000 shares out of those grants.  Final vesting will occur on June
     30, 1999 if still employed by the Company or an affiliate.  The value of
     the 5,000 shares as of December 31, 1997 is $175,625.  Dividends will be
     accrued and paid after the end of the three-year period on the shares
     earned.

(6)  Represents 200 shares, with a value of $7,025 as of December 31, 1997, of
     DQE Common Stock awarded as part of the consideration for the signing of a
     Non-Competition and Confidentiality Agreement.  Dividends are paid
     quarterly.

Supplemental Tables

    The following tables provide information with respect to options to purchase
DQE Common Stock and tandem stock appreciation rights in 1997 under the DQE,
Inc. Long-Term Incentive Plan.

    Option grants are structured to align 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 $35.125 per share to $52.6875 per share),
stockholder value would increase an estimated $1,674,984,293, while the value of
the grants to the individuals listed below would increase an estimated five-
tenths of one percent ($9,587,714) of the total gain realized by all
stockholders.

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

(1)  These grants represent performance stock options with tandem stock
     appreciation rights and stock-for-stock (reload) options.

                                       3

(2)  These grants 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 include tandem stock appreciation rights and
     dividend equivalent accounts and stock-for-stock options.

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

(4)  The exercise price of the options is the fair market value of DQE Common
     Stock on the date such options were granted.  The exercise price may be
     payable in cash or previously owned shares of DQE Common Stock held for at
     least six months.


(5)  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 option was calculated assuming an
     option life equal to the time period between the grant date and expiration
     date (i.e., from 3.93 to 10.00 years); a periodic risk-free rate of return
     equal to the yield of the U.S. Treasury note having a similar maturity date
     as the option expiration date, as reported by Bloomberg Financial Markets
     on the grant date (i.e., from 5.75% to 6.67%); an initial quarterly
     dividend immediately following the option grant date (i.e., from $0.34 to
     $0.36), with an expected growth rate of 5.0% per year as estimated by
     "Value Line Ratings and Reports", dated December 12, 1997; and an expected
     monthly stock price volatility as reported by Bloomberg Financial Markets
     over approximately the same length of time as the option life as of the
     month of the grant, (i.e., from 12.40% to 15.60%).  No adjustments to the
     grant date present values have been made with respect to exercise
     restrictions, forfeiture, or early exercise.

     Compensation utilized for pension formula purposes includes salary and
bonus reported in columns (c) and (d) of the Summary Compensation Table and
stock option compensation prior to March 1, 1994.  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 if commenced prior to age 60 or
upon election of certain options under which benefits are payable to survivors
upon the death of the employee.  Pension amounts set forth in the above table
reflect the integration with social security of the tax-qualified retirement
plans.  Retirement benefits are also subject to offset by other retirement plans
under certain conditions.

     The current covered compensation and current years of credited service for
Messrs. Marshall and Schwass respectively are $381,689 and 20; and $370,044 and
24.  The average covered compensation and current years of credited service for
Mr. Roque are $211,181 and 6.  The current years of credited service for Mr.
Brandenberger and Mr. Cross are 38 and 6, respectively.  Messrs. Roque and Cross
are not vested in the Retirement Plan.

Change of Control Agreements and Prior Employment Agreements
 
     DQE and its affiliates have entered into severance agreements (the "DQE
Severance Agreements") with David D. Marshall, James E. Cross, Victor A. Roque,
Gary L. Schwass, and Gary R. Brandenberger, and with eight other officers of DQE
or its affiliates, providing benefits upon a Change in Control (as defined
below).  The DQE Severance Agreements provide for payments and certain other
benefits to the officer if the officer's employment is terminated by the officer
after a Constructive Discharge (as defined below), or is terminated by DQE for
any reason other than death, disability or cause at any time during the period
that begins on the date of a Change of Control and ends 36 months after the
closing of the transactions giving rise to such Change in Control.  The payment
will be a lump sum amount equal to (i) three times the officer's current annual
base pay and target bonus opportunity at the time of the termination, (ii) an
amount intended to compensate the officer for the loss of long-term incentive
benefits, and (iii) the amount of forfeitures, if any, and expected
contributions for the 36 months following the termination under DQE's 401(k)
Plan.  In addition, the officer will receive a lump sum payment equal to the
actuarial value of the excess of (x) the benefits payable to the officer under
the Retirement Plan of DQE and the Supplemental Executive Retirement Plan of DQE
(the "Retirement Plans"), assuming three additional years of participation by
the officer in the Retirement Plans, over (y) the actual benefit payable to the
officer under the Retirement Plans.  Medical, disability and life insurance
benefits also will continue for the same 36-month period.  The officer also is
entitled to such payments and benefits if the employee voluntarily terminates
his or her employment in the thirteenth month following the closing of the
transaction giving rise to the Change in Control, provided that the 36 month
payment and benefit period would be reduced to 24 months and payments and
benefits would be reduced, if necessary, to avoid the excise tax under Section
4999 of the Code.

     In addition to standalone non-competition agreements with Messrs. Marshall,
Roque, Cross, and Brandenberger, the DQE Severance Agreements also provide that
these officers will not disclose confidential information about the company or
its affiliates; compete directly or indirectly with the Company or any of its
affiliates in a specified geographic area; solicit the business of certain
customers and suppliers of the Company; or induce any employee of the Company or
its affiliates to leave his or her current employment, each for specified
periods of time following the termination of his or her employment with the
Company.

     Messrs. Marshall, Schwass, and Cross had prior employment agreements with
the Company.  The officers and the Company have agreed that on the date of a
Change in Control, prior employment agreements will terminate and the provisions
thereof will no longer be in effect; provided, if the announced transaction with
Allegheny Energy, Inc. closes, the termination of the employment agreements is
final.  However, if the Board determines the transaction will not close, and the
officer is an employee of the Company or an affiliate thereof on the date the
Board so determines, then on such date the Employment Agreement will be
reinstated in all respects with the Employment Agreement's remaining term being
the same as the remaining term of the Employment Agreement on the date of the
Change of Control.  In addition, it is intended that the termination provisions
of the DQE Severance Agreements are in lieu of, and not in addition to,
termination or severance payments and benefits provided under the Company's
other termination or severance plans or agreements.

                                       7
<PAGE>
 
          The officer will also be entitled to a tax gross-up payment if (i) it
is determined that any payment (and the value of any benefits) received or to be
received under his or her DQE Severance Agreement would be subject to the excise
tax imposed by Section 4999 of the Code and (ii) the payments (and the value of
any benefits) to be received in excess of 300% of the base amount (as that term
is defined in Section 280G of the Code) exceeds 10% of the total payments and
benefits due pursuant to the DQE Severance Agreements.  Otherwise, the payments
and benefits received or to be received pursuant to the DQE Severance Agreements
will be reduced to an amount which will not be subject to such excise tax.
"Change in Control" is defined in the DQE Severance Agreements as, among other
things, the public announcement of a transaction approved by the DQE Board
involving a merger of DQE other than a merger in which the outstanding voting
securities of DQE immediately prior to the merger continue to represent at least
80% of the outstanding voting securities of DQE or the surviving entity
immediately after the merger.  The Merger constitutes such a merger and
therefore the public announcement of the DQE Board's approval of the Merger
constituted  a Change in Control for purposes of the DQE Severance Agreements,
unless and until the Merger is abandoned.  "Constructive Discharge" is defined
in the DQE Severance Agreements as, among other things, (i) a requirement that
the officer be based at any office or location more than 50 miles from
Pittsburgh, Pennsylvania, other than an office or location within 35 miles of
the principal executive offices of DQE, Duquesne Light, or the parent of DQE;
(ii) the reduction of the officer's compensation or benefits, unless part of a
reduction for all executive officers of DQE, Duquesne Light or any parent
thereof; (iii) the material failure of DQE to comply with the terms of the
officer's DQE Severance Agreement; or (iv) prior to the closing of the
transaction giving rise to the Change in Control, a material decrease in the
employee's positions, titles, authority or duties.  If the employment of all
officers with DQE Severance Agreements were terminated, the aggregate cost to
DQE under the DQE Severance Agreements would not exceed $20,000,000.

Directors' Fees and Plans

     Directors who are not employees are compensated for their Board service by
a combination of DQE Common Stock and cash.  They receive an annual Board
retainer of $15,000 in cash for service to the Company and its affiliates,
payable in twelve monthly installments, and 250 shares of DQE Common Stock,
payable annually.  Each director also receives a fee of $1,000 for each Board
and committee meeting attended.  Directors who are employees of the Company or
any of its affiliates do not receive fees for their services as directors.

     In order to increase directors' stock-based compensation and thus
strengthen the link between directors' compensation and stockholder interests,
the Board adopted a new stock plan in 1996 under which new non-employee
directors will each receive up to 4,150 shares of restricted DQE Common Stock
that will vest at the rate of 50% after five years of service as a director plus
an additional 10% per year in years six through ten.  Unvested shares are
forfeited if the recipient ceases to be a director.

     Each director under the age of 72 who is not an employee may elect under a
directors' deferred compensation plan to defer receipt of a percentage of his or
her director's remuneration until after termination of service as a director.
Deferred compensation may be received in one to ten annual installments
commencing, with certain exceptions, on the 15th day of January of the year
designated by the director.  Interest accrues quarterly on all deferred
compensation at a rate equal to a specified bank's prime lending rate.  Dr. Berg
and Dr. Mehrabian elected to participate in the plan for 1997.  Dr. Mehrabian
resigned from the Board effective September 30, 1997.

     As part of its overall program to promote charitable giving, the Company
has a Charitable Giving Program for all directors funded by Company-owned life
insurance policies on the directors.  Upon the death of a director, the Company
will donate up to five hundred thousand dollars, payable in ten equal annual
installments, to one or more qualifying charitable organizations recommended by
the director and reviewed and approved by the Employment and Community Relations
Committee.  A director must have Board service of 60 months or more in order to
qualify for the full donation amount, with service of less than 60 months
qualifying for an incremental donation.  The program does not result in any
material cost to the Company.

     The Company provides Business Travel Insurance to its non-employee
directors as part of its Business Travel Insurance Plan for Management
Employees.  In the event of accidental death or dismemberment, benefits of up to
$400,000 per individual are provided.  The program does not result in any
material cost to the Company.

     Directors can participate in the Company's College Matching Gift Program
which provides a dollar-for-dollar match of a gift of cash or securities, up to
a maximum of $5,000 per donor during any one calendar year to an accredited, non
profit, non proprietary degree granting college, university, or junior college
located within the United States or one of its possessions which is recognized
by the Internal Revenue Service as eligible to receive tax-deductible
contributions.  The program does not result in any material cost to the Company.


Compensation Committee Interlocks and Insider Participation

     The members of the Compensation Committee are Dr. Boyce and Messrs. Bozzone
and Falk.  No member of the Compensation Committee was at any time during 1997
or at any other time an officer or employee of the Company.
