Re: Performance Award  Two-Year Cycle Grant

[Name of
participant]

It is my pleasure to notify you that effective January 10, 2007, the Compensation Committee of the Board of Directors (the
Committee) of Duquesne Light Holdings, Inc. (DLH) granted you a Performance Award of <        > shares of Common Stock, no par value, of DLH (DLH Common
Stock) as set forth on your Performance Award Acceptance Form (enclosed). Your Performance Award is granted under, and subject to the terms and conditions of, the Duquesne Light Holdings, Inc. 2002 Long-Term Incentive Plan, as it may be
amended from time to time (the Plan), and to the further conditions set forth in this letter.

Definitions

Change in Control means, and shall be deemed to have occurred upon, the first to occur of any of the following events:

(a) The acquisition by any individual, entity, or group (a Person), including a person within the
meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the Exchange Act), of beneficial ownership within the meaning of Rule 13d-3 promulgated under the Exchange Act, of twenty percent
(20%) or more of either: (i) the then outstanding shares of common stock of DLH (the Outstanding Common Stock); or (ii) the combined voting power of the then outstanding securities of DLH entitled to vote generally
in the election of directors (the Outstanding Voting Securities); excluding, however the following: (A) any acquisition directly from DLH (excluding an acquisition resulting from the exercise of an exercise, conversion, or

(b) During any twenty-four (24) consecutive month period, the individuals who, at
the beginning of such period, constitute the Board of Directors of DLH (the Incumbent Directors) cease for any reason other than death to constitute at least a majority thereof, provided, however, that a director who was not a
director at the beginning of such twenty-four (24) month period shall be deemed to have satisfied such twenty-four (24) month requirement (and be an Incumbent Director) if such director was elected by, or on the recommendation of or with
the approval of, at least two-thirds (2/3) of the directors who then qualified as Incumbent Directors either actually (because they were directors at the beginning of such period) or by prior operation of the provisions of this clause (b);

(c) The consummation of a reorganization, merger or consolidation of DLH or sale or other disposition of all or
substantially all of the assets of DLH (a Corporate Transaction); excluding, however, a Corporate Transaction pursuant to which: (i) all or substantially all of the individuals or entities who are the beneficial owners,

shares of common stock, and the combined voting power of the outstanding securities of such corporation entitled to vote generally in the election of directors, as the case may be, of the corporation resulting from such Corporate Transaction
(including, without limitation, a corporation, which as a result of such transaction owns DLH or all or substantially all of DLHs assets either directly or indirectly) in substantially the same proportions relative to each other as their
ownership, immediately prior to such Corporate Transaction, of the Outstanding Common Stock and the Outstanding Voting Securities, as the case may be; (ii) no Person (other than: DLH; any employee benefit plan (or related trust) sponsored or
maintained by DLH or any corporation controlled by DLH; the corporation resulting from such Corporate Transaction; and any Person which beneficially owned, immediately prior to such Corporate Transaction, directly or indirectly, twenty-five percent
(25%) or more of the Outstanding Common Stock or the Outstanding Voting Securities, as the case may be) will beneficially own, directly or indirectly, twenty-five percent (25%)or more of, respectively, the outstanding shares of common stock of
the corporation resulting from such Corporate Transaction or the combined voting power of the outstanding securities of such corporation entitled to vote generally in the election of directors; and (iii) individuals who were members of the
Incumbent Board will constitute at least a majority of the members of the board of directors of the corporation resulting from such Corporate Transaction; or

(d) The consummation of a plan of complete liquidation or dissolution of DLH.

Notwithstanding the foregoing, a Change in Control will not be deemed to have occurred by reason of a distribution of the voting

Cumulative EBITDA means DLHs cumulative earnings before interest, taxes,
depreciation, amortization from the period beginning January 1, 2007 and ending on the date as of which Cumulative EBITDA is determined.

Performance Award means an award of an opportunity to earn a number of shares of DLH Common Stock during the Performance Period.

Performance Period means the period beginning on January 1, 2007 and continuing until December 31, 2008.

The Plan

Your Performance Award is subject to the terms and
conditions of the Plan. This letter agreement is the award agreement referred to in Section 7(A)(i) of the Plan. If there is any conflict between the Plan and this letter agreement, the provisions of the Plan will control, except as expressly
set forth in the next two sections (Change in Control and Other Agreements). Any dispute or disagreement which may arise under or in any way relate to the interpretation or construction of the Plan or this letter agreement will be
resolved by the Committee in its sole and absolute discretion and the decision will be final, binding and conclusive for all purposes.

Change in
Control

Upon the occurrence of a Change in Control, stock certificates (or, at the discretion of the Committee, an amount in cash or a combination
of cash and stock certificates, with the cash in each case representing the fair market value of the stock certificates that would otherwise be due under the Performance Award) representing a Cumulative EBITDA Reward (as defined below) equal to the
greater of (i) 100% of the Performance Award (defined below) or (ii) the the actual Performance Award earned based upon Cumulative EBITDA as of the date of the Change in Control shall be delivered to the participant as soon as reasonably
practicable after the date of the Change in Control.

Other Agreements

Notwithstanding any provision hereof to the contrary, if you are a party to an employment agreement, change in control, severance, or similar plan, policy or agreement that provides for accelerated payment and/or
other modifications of the terms and/or conditions of your Performance Awards or other stock-based awards upon the happening of certain events (including, but not by way of limitation, changes in control and/or terminations of employment), the
provisions of such other plan, policy or agreement, as the case may be, shall supercede the provisions contained in this agreement to the extent such other provisions would provide benefits to you greater than those provided in this agreement.

Determination of Performance Award

Subject to your timely execution and return of the enclosed Performance Award Acceptance Form, the extent to which your Performance Award will be awarded to you (your Cumulative EBITDA Reward) at
the end of the Performance Period will be determined by the Committee, in its sole and absolute discretion. The Committees determination will be based on Cumulative EBITDA. As promptly as administratively feasible but in no event later than
the sixty (60) days following the last day of the Performance Period (or, if applicable the date of a Change in Control or the date of your death), the Committee shall determine Cumulative EBITDA as of such date.

Your Cumulative EBITDA Reward shall be the number of shares of DLH Common Stock determined by multiplying (i) the number of shares constituting your Performance
Award as set forth in the first paragraph of this letter agreement by (ii) the Percent of Performance Award Earned with respect to the Cumulative EBITDA for the applicable period as set forth below:



|                  |  |                                  
|----------------- |  | ---------------------------------
|Cumulative EBITDA |  | Percent ofPerformanceAward Earned
|$1,092,300,000    |  | 150%                             
|$   728,200,000   |  | 100%                             
|$   364,100,000   |  | 50%                              

In determining the final Percent of Performance Award Earned, the Committee shall use straight-line interpolation
between the percentiles provided in the table above for Cumulative EBITDA. No Cumulative EBITDA Reward will be earned for Cumulative EBITDA less than the $364,100,000. No additional Cumulative EBITDA Reward will be earned for Cumulative EBITDA
greater than $1,092,300,000.

Certificates

Subject to the withholding obligations and any requirements of this letter agreement then applicable, within 70 days after the end of the Performance Period (or, if applicable, the date of a Change in Control or the date of your death), DLH
shall deliver to you certificates representing the Cumulative EBITDA Reward, if any. Unless you otherwise direct DLH in writing, DLH will register the certificate(s) in your name and will cause such certificates to be delivered to you at the address
specified by you in writing. Notwithstanding anything to the contrary in this letter agreement, the Committee may, in its sole discretion, pay your Cumulative EBITDA Reward in the form of cash in an amount representing the fair market value of the
stock certificates that would otherwise be delivered under your Cumulative EBITDA Reward.

Termination of Employment

Your Cumulative EBITDA Reward also is subject to the provisions of the Plan. If your employment with DLH and each affiliate of DLH is terminated prior to the completion of the Performance Period for reasons other
than retirement under any retirement plan of DLH or any affiliate of DLH, death or disability (as described in the Plan), any Performance Award for the then uncompleted portion of the Performance Period shall be forfeited automatically.

Retirement. If your employment with DLH and each affiliate of DLH is terminated prior to the completion of the Performance Period for reason of
retirement under any retirement plan of DLH or any affiliate of DLH, you shall be entitled to receive a pro rata Cumulative EBITDA Reward for the uncompleted portion of the Performance Period determined:

(a) when the Cumulative EBITDA Rewards for all other participants who received Performance Awards for the Performance Period are
determined;

(b) based on the actual Cumulative EBITDA achieved for the Performance Period and your Performance Award;

(c) pro rated by multiplying the number of shares of DLH Common Stock (or the cash value thereof) you would have received
if you completed the Performance Period by a fraction, the numerator of which shall be the number of months of the Performance Period completed before your termination of employment and the denominator of which shall be the total number of months in
the Performance Period; and

(d) cash and/or stock certificates representing the number determined above shall be delivered
at the same time as all other cash and/or certificates for such Performance Period are delivered to participants who completed the Performance Period.

Death. If your employment with DLH and each affiliate of DLH is terminated prior to the completion of the Performance Period due to your death, your legal representative shall be entitled to receive a pro rata Cumulative EBITDA
Reward for the uncompleted portion of the Performance Period determined:

(a) as soon as reasonably practicable after the
date of your death;

(b) based on the Cumulative EBITDA achieved as of the end of the month in which your death occurs;



5



---

(c) pro rated by multiplying the number of shares of DLH Common Stock you would have
received if you completed the Performance Period by a fraction, the numerator of which shall be the number of months of the Performance Period completed before your death and the denominator of which shall be the total number of months in the
Performance Period; and

(d) cash and/or stock certificates representing the number determined above shall be delivered as
soon as reasonably practicable after the date of your death.

Disability. If your employment by DLH or an affiliate is terminated due to disability
(as described in the Plan), you (or your legal representative) shall be entitled to receive your Cumulative EBITDA Reward for the uncompleted portion of the Performance Period determined as if you were an active employee for the duration of the
Performance Period.

Dividend Equivalents

At
the time that DLH issues and transfers to you shares of DLH Common Stock (or pays any portion thereof in cash) in accordance with the preceding two paragraphs, DLH shall transfer to you an amount in cash equal to the fair market value of the
dividends that would otherwise have been paid on such shares from January 1, 2007 to the date the shares are issued and transferred to you (or any portion thereof is paid to you in cash) had the shares been issued and transferred to you on
January 1, 2007. The fair market value of a dividend shall, in the case of a cash dividend, be the amount of such cash dividend and, in the case of a dividend payable in shares of DLH stock, the fair market value of such DLH stock on the date
the dividend equivalent amount under this paragraph is paid.

Acceptance Form

Enclosed is one copy of your Performance Award Acceptance Form. IF YOU DESIRE TO ACCEPT THE PERFORMANCE AWARD, YOU SHOULD SIGN THE PERFORMANCE AWARD ACCEPTANCE FORM IN DUPLICATE AND RETURN ONE COPY TO MAUREEN L.
HOGEL. YOUR PERFORMANCE AWARD WILL BE DEEMED TO BE CANCELLED AND BE VOID IF THE SIGNED PERFORMANCE AWARD ACCEPTANCE FORM IS NOT RETURNED TO DLH BY JANUARY 31, 2007.

Information Statement

You previously received or will be receiving an Information Statement which describes
the Plan. You should read the Information Statement, together with the Plan and this letter agreement for a full understanding of the Performance Award granted to you. Until your Performance Award is earned by you, you will continue to receive
notification if there is a material amendment to the Plan or a change in the law which impacts your rights under the Plan.

Officers and Affiliates  Restrictions

There are certain legal restrictions under the federal securities laws upon officers and affiliates who receive grants of Performance Awards and/or sell shares acquired under the Plan. If you are an officer or
affiliate of DLH, you must consult the Corporate Secretary before selling shares under the Plan. Such sales may be restricted in order to ensure compliance with the federal securities laws. You may also consult the Corporate Secretary if you have
any questions concerning your status as an affiliate of DLH as defined in the Plan.

Federal Income Tax Consequences

Information with respect to the Federal income tax consequences of the receipt of Performance Awards, whether in cash or DLH Common Stock, and the subsequent
disposition of any shares of DLH Common Stock acquired under the Plan, appears in the Information Statement under the caption Federal Income Tax Consequences. The Federal income tax consequences are complex. Accordingly, you are
encouraged to carefully read the material which was provided and to consult your personal tax adviser with specific reference to your own tax situation.

Withholding of Taxes

DLH will advise you as to the amount of any Federal income, employment or excise taxes required to be withheld
as a result of the cash part of your award and the delivery of DLH Common Stock in connection with a Performance Award, and that state or local income or employment taxes may also be required to be withheld. You will be required to pay any such
taxes directly to DLH in cash within ten days after DLHs notification, and such payment will be made before distribution of stock certificates or cash to you. In lieu of payment of cash, however, you may satisfy your withholding obligation by
one, or any combination, of the following: (i) delivering previously acquired shares of DLH Common Stock (valued at their fair market value on the date of delivery) (ii) having cash withheld from any cash otherwise payable to you with
respect to your Performance Award and (iii) having shares of DLH Common Stock withheld from any shares otherwise issuable to you with respect to your Performance Award (valued at their fair market value on the date of such withholding).

If you do not pay any taxes required to be withheld, DLH may withhold such taxes from any other compensation to which you are entitled from DLH. You agree
to hold DLH harmless in acting to satisfy the withholding obligation in this manner if it becomes necessary to do so. Further information regarding withholding of taxes appears in the Information Statement under the caption, Federal Income Tax
Consequences  Tax Withholding.

Investment Representation

You shall deliver to the Committee, upon demand by the Committee, at the time of any payment your Cumulative EBITDA Reward which contains shares of DLH Common Stock, a written representation that the shares to be
acquired are to be acquired for investment and not for resale or with a view to the distribution thereof. Upon such demand, delivery of such representation prior to delivery of any shares of DLH Common Stock shall be a condition precedent to your
right to receive any shares.

No Rights as Shareholder

You shall have no rights as a shareholder of DLH with respect to the shares of DLH Common Stock subject to the Performance Award evidenced hereby unless and until a certificate for shares of DLH Common Stock is issued to you.

Performance Awards Not a Bar to Corporate Event

The existence
of the Performance Award granted hereunder shall not affect in any way the right or the power of DLH or its shareholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in DLHs capital structure
or its business, or any merger or consolidation of DLH, or any issue of bonds, debentures, preferred or prior preference stocks ahead of or affecting the DLH Common Stock or the rights thereof, or the dissolution or liquidation of DLH, or any sale
or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of similar character or otherwise.

General Restriction

To the extent any Performance Award is denominated in DLH Common Stock under this letter agreement, it shall be
subject to the requirement that if at any time the Committee shall determine that any listing or registration of the shares of DLH Common Stock or any consent or approval of any governmental body or any other agreement or consent is necessary or
desirable as a condition of the issuance of shares of DLH Common Stock or cash in satisfaction thereof, such issuance of shares of DLH Common Stock may not be consummated unless such requirement is satisfied in a manner acceptable to the Committee.
DLH shall in no event be obligated to register any securities pursuant to the Securities Act of 1933 (as the same shall be in effect from time to time) or to take any other affirmative action to cause the issuance of shares pursuant to the
distribution of Cumulative EBITDA Rewards to comply with any law or regulation of any governmental authority.

Determinations of Committee

The actions taken and determinations of the Committee made pursuant to this letter agreement and of the Committee pursuant to the Plan shall be
final, conclusive and binding upon DLH and upon you. No member of the Committee shall be liable for any action taken or determination made relating to this letter agreement or the Plan if made in good faith.

---

Miscellaneous

Your Performance Award may not be transferred otherwise than by will or by the law of descent and distribution. During your lifetime, any Cumulative EBITDA Rewards shall be payable only to you. No assignment or transfer of a Performance
Award or of the rights represented thereby, whether voluntary or involuntary, by operation of law or otherwise (except by will or the laws of descent and distribution), shall vest in the assignee or transferee any interest or right herein
whatsoever, and immediately upon such purported assignment or transfer, the Performance Award shall terminate and become of no further effect.

This letter
agreement does not confer any right on you to continue in the employ of DLH or its affiliates, or interfere in any way with the rights of DLH or its affiliates to terminate your employment.

Whenever the word you is used in any provision of this letter agreement under circumstances where the provision should logically be construed to apply to
your executors, administrators, or the person or persons to whom the Performance Award may be transferred by will or by the laws of descent and distribution, the word you shall be deemed to include such person or persons.

The Plan, or any part thereof, may be terminated or may, from time to time be amended, in accordance with the Plan; provided, however, the termination or amendment of
the Plan shall not, without your consent, affect your rights under this letter agreement.

This letter agreement shall be binding upon the successors and
assigns of DLH and upon your legal representatives, heirs and legatees. This letter agreement, along with the Plan and the Information Statement, constitutes the entire agreement between you and DLH with respect to the Performance Award granted to
you and supersedes all prior agreements and understandings, oral or written, between you and DLH with respect to the subject matter of this letter agreement. This letter agreement may be amended only by a written instrument signed by you and DLH and
will be governed by, and construed and enforced in accordance with, the laws of the Commonwealth of Pennsylvania.

Between the date of this letter
agreement and the date your Performance Award is paid to you, you will receive copies of all reports, proxy statements and other communications distributed generally to the shareholders of DLH.

It is recommended that you establish a file for this letter and enclosures as well as any other material you receive regarding the Plan, including the Information
Statement.
