2

 

        B.    Period for Grants of Awards.    Awards may be made as provided herein for a period of 10 years after
May 24, 2002. 

        C.    Termination.    The Plan will continue in effect until all matters relating to the payment of outstanding Awards
and administration of the Plan have been settled. 

        4.    Plan Administration.    The Chief Executive Officer is the Plan Administrator and has sole authority (except as
specified otherwise herein) to determine all questions of interpretation and application of the Plan, or of the terms and conditions pursuant to which Awards are granted, exercised or forfeited under
the Plan provisions, and, in general, to make all determinations advisable for the administration of the Plan to achieve its stated purpose. Without limiting the generality of the foregoing, the Plan
Administrator may modify, amend, extend or renew outstanding Awards, or accept the surrender of outstanding Awards and substitute new Awards (provided, however, that, except as provided in
Section 15H of the Plan, any modification that would materially adversely affect any outstanding Award shall not be made without the consent of the Participant, and provided, further, that no
modification, amendment or substitution that results in repricing a Stock Option to a lower exercise price, other than to reflect an adjustment made pursuant to Section 15H, shall be made
without prior stockholder approval). 

        The
Plan Administrator's determinations under the Plan (including without limitation, determinations of the persons to receive Awards, the form, amount and timing of such Awards, the
terms and provisions of such Awards and any agreements evidencing such Awards) need not be uniform and may be made by the Administrator selectively among persons who receive, or are eligible to
receive, Awards under the Plan, whether or not such persons are similarly situated. Such determinations shall be final and not subject to further appeal. 

        The
Plan Administrator may delegate his/her authority under the Plan. 

        5.    Eligibility.    Each officer (who is not a participant under the Company's Executive Long-Term
Incentive Plan), senior management level or key employee of the Company and its Subsidiaries may be designated by the Plan Administrator as a Participant, from time to time,
with respect to one or more Awards. No employee of the Company or its Subsidiaries shall have any right to be granted an Award under this Plan. The Plan Administrator may also grant Awards to
individuals in connection with hiring (as an officer, senior management level or key employee), retention or otherwise, prior to the date the individual first performs services for the Company or a
Subsidiary; provided, however, that such Awards shall not become vested or exercisable prior to the date the individual first commences performance of such services. 

        6.    Grant of Awards and Limitation of Number of Shares Awarded.    The Plan Administrator may, from time to time,
grant Awards to one or more Eligible Persons, provided that subject to any adjustment pursuant to Section 15H, the aggregate number of shares of Stock subject to Awards that may be delivered
under this Plan may not exceed five million (5,000,000) shares. Shares delivered by the Company under the Plan may be authorized and unissued Stock, Stock held in the treasury of the Company, or Stock
purchased on the open market (including private purchases) in accordance with applicable securities laws. 

        Any
shares of Stock covered by an Award (or portion of an Award) granted under the Plan that is forfeited or canceled, expires or is settled in cash, including the settlement of tax
withholding obligations using shares, shall be deemed not to have been delivered for purposes of determining the maximum number of shares available for delivery under the Plan. Likewise, if any Option
granted under the Plan is exercised by tendering shares of Stock to the Company as full or partial payment for such exercise under the Plan, only the number of shares issued net of the shares tendered
shall be deemed delivered for purposes of determining the maximum number of shares available for delivery under the Plan. 

3

 

        The
Plan Administrator may permit or require a recipient of an Award to defer all or part of such individual's receipt of the payment of cash or the delivery of Stock that would
otherwise be due to such individual by virtue of the exercise of, payment of, or lapse or waiver of restrictions respecting, any Award. If any such payment deferral is required or permitted, the Plan
Administrator shall, in his/her sole discretion, establish rules and procedures for such payment deferrals. 

        7.    Service-Based Restricted Stock and Restricted Stock Unit Awards.

        A.    Grants of Service-Based Restricted Shares or Units.    One or more shares of Restricted Stock or Restricted
Stock Units may be granted to any Eligible Person. The Service-Based Restricted Stock will be issued or Restricted Stock Unit granted to the Participant on the Date of Grant without the payment of
consideration by the Participant. The Service-Based Restricted Stock will be issued or Restricted Stock Unit granted in the name of the Participant and will bear a restrictive legend prohibiting sale,
transfer, pledge or hypothecation of the Service-Based Restricted Stock or Restricted Stock Unit until the expiration of the restriction period. 

        The
Plan Administrator may also impose such other restrictions and conditions on the Service-Based Restricted Stock or Restricted Stock Unit as he/she deems appropriate. 

        Upon
issuance to the Participant of the Service-Based Restricted Stock, the Participant will have the right to vote the Service-Based Restricted Stock. Upon issuance to the Participant
of the Restricted Stock or grant of the Restricted Stock Unit and subject to the Plan Administrator's discretion, the Participant will have the right to receive the cash dividends (or Dividend
Equivalents as provided in Section 11) distributable with respect to such shares or units, with such dividends or Dividend Equivalents treated as compensation to the Participant. The Plan
Administrator, in his/her sole discretion, may direct the accumulation and payment of distributable dividends to the Participant at such times, and in such form and manner, as determined by the Plan
Administrator. 

        B.    Restriction Period.    At the time a Service-Based Restricted Stock or Restricted Stock Unit Award is granted,
the Plan Administrator will establish a restriction period applicable to such Award which will be not less than one year and not more than ten years. Each Restricted Stock or Restricted Stock Unit
Award may have a different restriction period, at the discretion of the Plan Administrator. 

        C.    Forfeiture or Payout of Award.    In the event a Participant ceases employment during a restriction period, a
Service-Based Restricted Stock or Restricted Stock Unit Award is subject to forfeiture or payout (i.e., removal of restrictions) as follows: (a) Termination—the Service-Based
Restricted Stock or Restricted Stock Unit Award is completely forfeited; or (b) Retirement, Disability or death—payout of the Service-Based Restricted Stock or Restricted Stock Unit
Award is prorated for service during the period; provided, however, that the Plan Administrator may modify the above if he/she determines at his/her sole discretion that special circumstances warrant
such modification. 

        Any
shares of Service-Based Restricted Stock which are forfeited will be transferred to the Company. 

        Upon
completion of the restriction period, all Award restrictions will expire and new certificates representing the Award will be issued (the payout) without the restrictive legend
described in Section 7A. 

        D.    Waiver of Section 83(b) Election.    Unless otherwise directed by the Plan Administrator, as a condition
of receiving an Award of Service-Based Restricted Stock, a Participant must waive in writing the right to make an election under Section 83(b) of the Code to report the value of the
Service-Based Restricted Stock as income on the Date of Grant. 

4

 

        8.    Stock Options.

        A.    Grants of Options.    One or more Options may be granted to any Eligible Person on the Date of Grant without the
payment of consideration by the Participant. 

        B.    Stock Option Agreement.    Each Option granted under the Plan will be evidenced by a "Stock Option Agreement"
between the Company and the Participant containing provisions determined by the Plan Administrator, including, without limitation, provisions to qualify Incentive Stock Options as such under
Section 422 of the Code if directed by the Plan Administrator at the Date of Grant; provided, however, that each Incentive Stock Option Agreement must include the following terms and
conditions: (i) that the Options are exercisable, either in total or in part, with a partial exercise not affecting the exercisability of the balance of the Option; (ii) every share of
Stock purchased through the exercise of an Option will be paid for in full at the time of the exercise; (iii) each Option will cease to be exercisable, as to any share of Stock, at the earliest
of (a) the Participant's purchase of the Stock to which the Option relates, (b) the Participant's exercise of a related Stock Appreciation Right, or (c) the lapse of the Option;
(iv) Options will not be transferable by the Participant except by Will or the laws of descent and distribution and will be exercisable during the Participant's lifetime only by the Participant
or by the Participant's guardian or legal representative; and (v) notwithstanding any other provision, in the event of a public tender for all or any portion of the Stock or in the event that
any proposal to merge or consolidate the Company with another company is submitted to the stockholders of the Company for a vote, the Plan Administrator, in his/her sole discretion, may declare any
previously granted Options to be immediately exercisable. 

        C.    Option Price.    The Option price per share of Stock will be set by the grant, but will be not less than 100% of
the Fair Market Value at the Date of Grant. 

        D.    Form of Payment.    At the time of the exercise of the Option, the Option price will be payable in cash or in
other shares of Stock or in a combination of cash and other shares of Stock, in a form and manner as required by the Plan Administrator in his/her sole discretion. When Stock is used in full or
partial payment of the Option price, it will be valued at the Fair Market Value on the applicable date. 

        E.    Other Terms and Conditions.    The Option will become exercisable in such manner and within such Option Period
or Periods, not to exceed 10 years from its Date of Grant, as set forth in the Stock Option Agreement upon payment in full. Except as otherwise provided in this Plan or in the Stock Option
Agreement, any Option may be exercised in whole or in part at any time. 

        F.    Lapse of Option.    An Option will lapse upon the earlier of: (i) 10 years from the Date of Grant,
or (ii) at the expiration of the Option Period set by the grant. If the Participant ceases employment within the Option Period and prior to the lapse of the Option, the Option will lapse as
follows: (a) Termination—any unvested Option will lapse on the effective date of the Termination and any vested Option will lapse 90 days after the effective date of the
Termination; or (b) Retirement, Disability or death—any unvested Option will lapse on the effective date of the Retirement, Disability or death and any vested Option will lapse on
the earlier of 60 months after the effective date of the Retirement, Disability or death or at the expiration of the Option Period set by the Grant; provided, however, that the Plan
Administrator may modify the above if he/she determines in his/her sole discretion that special circumstances warrant such modification. 

        G.    Individual Limitation.    In the case of an Incentive Stock Option, the aggregate Fair Market Value of the Stock
for which Incentive Stock Options (whether under this Plan or another arrangement) in any calendar year are first exercisable will not exceed $100,000 with respect to such calendar year (or such other
individual limit as may be in effect under the Code on the Date of Grant) plus any unused portion of such limit as the Code may permit to be carried over. 

5

 

        9.    Performance-Based Restricted Stock or Restricted Stock Units/Performance Units.

        A.    Provision for Awards.    The Plan Administrator will determine a Performance Period and will determine the
performance objectives for each Participant's target performance award and the number of shares of Performance-Based Restricted Stock, Performance-Based Restricted Stock Units or Performance Units
subject to each target performance award. Performance objectives may vary from Participant to Participant and will be based upon such performance criteria or combination of factors as the Plan
Administrator deems appropriate, which may include, but not be limited to, the performance of the Participant, the Company, one or more Subsidiaries, or any combination thereof. Performance Periods
may overlap and Participants may participate simultaneously with respect to Performance Units or Performance-Based Restricted Stock or Performance-Based Restricted Stock Units for which different
Performance Periods are prescribed. 

        If
during the course of a Performance Period significant events occur as determined in the sole discretion of the Plan Administrator which the Plan Administrator expects to have a
substantial effect on a performance objective during such period, the Plan Administrator may revise such objective 

        B.    Performance-Based Restricted Stock Awards or Restricted Stock Unit Awards.

        (i)    Grants of Performance-Based Restricted Stock or Restricted Stock Units.    Subject to Section 9A, one or
more shares of Performance-Based Restricted Stock or Restricted Stock Unit may be granted to any Eligible Person. The Performance-Based Restricted Stock or Restricted Stock Unit will be issued to the
Participant on the Date of Grant without the payment of consideration by the Participant. The Performance-Based Restricted Stock or Restricted Stock Unit will be issued in the name of the Participant
and will bear a restrictive legend prohibiting sale, transfer, pledge or hypothecation of the Performance-Based Restricted Stock or Restricted Stock Unit until the expiration of the restriction
period. 

        The
Plan Administrator may also impose such other restrictions and conditions on the Performance-Based Restricted Stock or Restricted Stock Unit as he/she deems appropriate. 

        Upon
issuance to the Participant of the Performance-Based Restricted Stock, the Participant will have the right to vote the Performance-Based Restricted Stock. Upon issuance to the
Participant of the Performance-Based Restricted Stock or grant of the Restricted Stock Unit and subject to the Plan Administrator's discretion, the Participant will have the right to receive the cash
dividends (or Dividend Equivalents as provided in Section 11) distributable with respect to such shares or units, with such dividends or Dividend Equivalents treated as compensation to the
Participant. The Plan Administrator, in his/her sole discretion, may direct the accumulation and payment of distributable dividends to the Participant at such times, and in such form and manner, as
determined by the Plan Administrator. 

        (ii)    Restriction Period.    At the time a Performance-Based Restricted Stock or Restricted Stock Unit Award is
granted, the Plan Administrator will establish a restriction period applicable to such Award which will be not less than one year and not more than ten years. Each Performance-Based Restricted Stock
or Restricted Stock Unit Award may have a different restriction period, at the discretion of the Plan Administrator. 

        (iii)    Waiver of Section 83(b) Election.    Unless otherwise directed by the Plan Administrator, as a
condition of receiving an Award of Performance-Based Restricted Stock, a Participant must waive in writing the right to make an election under Section 83(b) of the Code to report the value of
the Performance-Based Restricted Stock as income on the Date of Grant. 

        C.    Performance Units.    Subject to Section 9A, one or more Performance Units may be earned by an Eligible
Person based on the achievement of preestablished performance objectives during a Performance Period. 

6

 

        D.    Forfeiture or Payout of Award.    As soon as practicable after the end of each Performance Period, the Plan
Administrator will determine whether the performance objectives and other material terms of the Award were satisfied. The Plan Administrator's determination of all such matters will be final and
conclusive. 

        As
soon as practicable after the date the Plan Administrator makes the above determination, the Plan Administrator will determine the Award payment for each Participant. 

        In
the event a Participant ceases employment during a Performance Period, the Performance-Based Restricted Stock, Performance-Based Restricted Stock Unit or Performance Unit Award is
subject to forfeiture or payout as follows: (a) Termination—the Performance-Based Restricted Stock, Performance-Based Restricted Stock Unit or Performance Unit Award is completely
forfeited; or (b) Retirement, Disability or death—payout of the Performance-Based Restricted Stock, Performance-Based Restricted Stock Unit or Performance Unit Award is prorated
taking into account factors including, but not limited to, service and the performance of the Participant during the portion of the Performance Period before employment ceased; provided, however, that
the Plan Administrator may modify the above if he/she determines in his/her sole discretion that special circumstances warrant such modification. 

        Any
shares of Performance-Based Restricted Stock which are forfeited will be transferred to the Company. 

        E.    Form and Timing of Payment.    With respect to shares of Performance-Based Restricted Stock or Restricted Stock
Units for which restrictions lapse, new certificates will be issued (the payout) without the restrictive legend described in Section 9B(i). Each Performance Unit is payable in cash or shares of
Stock or in a combination of cash and Stock, as determined by the Plan Administrator in his/her sole discretion. Such payment will be made as soon as practicable after the Award payment is determined. 

        10.    Stock Appreciation Rights.

        A.    Grants of Stock Appreciation Rights.    Stock Appreciation Rights may be granted under the Plan in conjunction
with an Option either at the Date of Grant or by amendment or may be separately granted. Stock Appreciation Rights will be subject to such terms and conditions not inconsistent with the Plan as the
Plan Administrator may impose. 

        B.    Right to Exercise; Exercise Period.    A Stock Appreciation Right issued pursuant to an Option will be
exercisable to the extent the Option is exercisable; both such Stock Appreciation Right and the Option to which it relates will not be exercisable during the six months following their respective
Dates of Grant except in the event of the Participant's Disability or death. A Stock Appreciation Right issued independent of an Option will be exercisable pursuant to such terms and conditions
established in the grant. Notwithstanding such terms and conditions, in the event of a public tender for all or any portion of the Stock or in the event that any proposal to merge or consolidate the
Company with another company is submitted to the stockholders of the Company for a vote, the Plan Administrator, in his/her sole discretion, may declare any previously granted Stock Appreciation Right
immediately exercisable. 

        C.    Failure to Exercise.    If on the last day of the Option Period, in the case of a Stock Appreciation Right
granted pursuant to an Option, or the specified Exercise Period, in the case of a Stock Appreciation Right issued independent of an Option, the Participant has not exercised a Stock Appreciation
Right, then such Stock Appreciation Right will be deemed to have been exercised by the Participant on the last day of the Option Period or Exercise Period. 

        D.    Payment.    An exercisable Stock Appreciation Right granted pursuant to an Option will entitle the Participant
to surrender unexercised the Option or any portion thereof to which the Stock Appreciation Right is attached, and to receive in exchange for the Stock Appreciation Right payment 

7

 

(in
cash or Stock or a combination thereof as described below) equal to either of the following amounts, determined in the sole discretion of the Plan Administrator at the Date of Grant:
(1) the excess of the Fair Market Value of one share of Stock at the date of exercise over the Option price, times the number of shares called for by the Stock Appreciation Right (or portion
thereof) which is so surrendered, or (2) the excess of the Book Value of one share of Stock at the date of exercise over the Book Value of one share of Stock at the Date of Grant of the related
Option, times the number of shares called for by the Stock Appreciation Right. Upon exercise of a Stock Appreciation Right not granted pursuant to an Option, the Participant will receive for each
Stock Appreciation Right payment (in cash or Stock or a combination thereof as described below) equal to either of the following amounts, determined in the sole discretion of the Plan Administrator at
the Date of Grant: (1) the excess of the Fair Market Value of one share of Stock at the date of exercise over the Fair Market Value of one share of Stock at the Date of Grant of the Stock
Appreciation Right, times the number of shares called for by the Stock Appreciation Right, or (2) the excess of the Book Value of one share of Stock at the date of exercise of the Stock
Appreciation Right over the Book Value of one share of Stock at the Date of Grant of the Stock Appreciation Right, times the number of shares called for by the Stock Appreciation Right. 

        The
Plan Administrator may direct the payment in settlement of the Stock Appreciation Right to be in cash or Stock or a combination thereof. Alternatively, the Plan Administrator may
permit the Participant to elect to receive cash in full or partial settlement of the Stock Appreciation Right, provided that (i) the Plan Administrator must consent to or disapprove such
election and (ii) unless the Plan Administrator directs otherwise, the election and the exercise must be made during the period beginning on the 3rd business day following the date of public
release of quarterly or year-end earnings and ending on the 12th business day following the date of public release of quarterly or year-end earnings. The value of the Stock to
be received upon exercise of a Stock Appreciation Right shall be the Fair Market Value of the Stock on the trading day preceding the date on which the Stock Appreciation Right is exercised. To the
extent that a Stock Appreciation Right issued pursuant to an Option is exercised, such Option shall be deemed to have been exercised, and shall not be deemed to have lapsed. 

        E.    Nontransferable.    A Stock Appreciation Right will not be transferable by the Participant except by Will or the
laws of descent and distribution and will be exercisable during the Participant's lifetime only by the Participant or by the Participant's guardian or legal representative. 

        F.    Lapse of a Stock Appreciation Right.    A Stock Appreciation Right will lapse upon the earlier of:
(i) 10 years from the Date of Grant; or (ii) at the expiration of the Exercise Period as set by the grant. If the Participant ceases employment within the Exercise Period and
prior to the lapse of the Stock Appreciation Right, the Stock Appreciation Right will lapse as follows: (a) Termination—any unvested Stock Appreciation Right will lapse on the
effective date of the Termination and any vested Stock Appreciation Right will lapse 90 days after the effective date of the Termination; or (b) Retirement, Disability or
death—any unvested Stock Appreciation Right will lapse on the effective date of the Retirement, Disability or death and any vested Stock Appreciation Right will lapse on the earlier of
60 months after the effective date of the Retirement, Disability or death or at the expiration of the Exercise Period set by the grant; provided, however, that the Plan Administrator may modify
the above if he/she determines in his/her sole discretion that special circumstances warrant such modification. 

        11.    Dividend Equivalents.

        A.    Grants of Dividend Equivalents.    Dividend Equivalents may be granted under the Plan in conjunction with an
Option or a separately awarded Stock Appreciation Right, at the Date of Grant or by amendment, without consideration by the Participant. Dividend Equivalents may also be granted under the Plan in
conjunction with Performance-Based Restricted Stock, Performance-Based Restricted 

8

 

Stock
Units or Performance Units, at any time during the Performance Period, without consideration by the Participant. 

        B.    Payment.    Each Dividend Equivalent will entitle the Participant to receive an amount equal to the dividend
actually paid with respect to a share of Stock on each dividend payment date from the Date of Grant to the date the Dividend Equivalent lapses as set forth in Section 11D. The Plan
Administrator, in his/her sole discretion, may direct the payment of such amount at such times and in such form and manner as determined by the Plan Administrator. 

        C.    Nontransferable.    A Dividend Equivalent will not be transferable by the Participant. 

        D.    Lapse of a Dividend Equivalent.    Each Dividend Equivalent will lapse on the earlier of (i) the date of
the lapse of the related Option or Stock Appreciation Right; (ii) the date of the exercise of the related Option or Stock Appreciation Right; (iii) the end of the Performance Period (or
if earlier, the date the Participant ceases employment) of the related Performance Units or Performance-Based Restricted Stock or Restricted Stock Unit Award; or (iv) the lapse date established
by the Plan Administrator on the Date of Grant of the Dividend Equivalent. 

        12.    Equity.    One or more shares of Stock may be granted to any Eligible Person, in such amounts, on such terms
and conditions, and for such consideration, including no consideration or such minimum consideration as may be required by law, as the Plan Administrator shall determine. An Equity Award may be
denominated in Stock or other securities, stock-equivalent units, securities or debentures convertible into Stock, or any combination of the foregoing and may be paid in Stock or other securities, in
cash, or in a combination of Stock or other securities and cash, all as determined in the sole discretion of the Plan Administrator. Unless the Plan Administrator determines otherwise, the vesting
period for Equity Awards shall be at least three years. 

        13.    Accelerated Award Payout/Exercise.

        A.    Change in Control.    Notwithstanding anything in this Plan document to the contrary, a Participant is entitled
to an accelerated payout or accelerated Option or Exercise Period (as set forth in Section 13B) with respect to any previously granted Award, upon the happening of a change in control. 

        A
change in control for purposes of this Section 13 means the occurrence of any one of the following events: 

        (i)    individuals
who, on January 24, 2003, constitute the Board (the "Incumbent Directors") cease for any reason to
constitute at least a majority of the Board, provided that any person becoming a director subsequent to January 24, 2003, whose election or nomination for election was approved by a vote of at
least two-thirds of the Incumbent Directors then on the Board (either by a specific vote or by approval of the proxy statement of the Company in which such person is named as a nominee for
director, without written objection to such nomination) shall be an Incumbent Director; provided, however, that no individual initially elected or
nominated as a director of the Company as a result of an
actual or threatened election contest with respect to directors or as a result of any other actual or threatened solicitation of proxies by or on behalf of any person other than the Board shall be
deemed to be an Incumbent Director; 

        (ii)    any
"person" (as such term is defined in Section 3(a)(9) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act") and as used in Sections 13(d)(3) and 14(d)(2) of the Exchange Act) is or becomes a "beneficial owner" (as defined in Rule 13d-3 under the Exchange
Act), directly or indirectly, of securities of the Company representing 20% or more of the combined voting power of the Company's then outstanding securities eligible to vote for the election of the
Board (the "Company Voting Securities"); provided, however, that the event described in this
paragraph (ii) shall not be deemed to be a Change in Control by virtue of any of the following acquisitions: (A) by the Company or any corporation with respect to which the 

9

 

Company
owns a majority of the outstanding shares of common stock or has the power to vote or direct the voting of sufficient securities to elect a majority of the directors (a
"Subsidiary Company"), (B) by any employee benefit plan (or related trust) sponsored or maintained by the Company or any Subsidiary Company,
(C) by any underwriter temporarily holding securities pursuant to an offering of such securities, (D) pursuant to a Non-Qualifying Transaction (as defined in
paragraph (iii)), or (E) pursuant to any acquisition by Participant or any group of persons including Participant (or any entity controlled by Participant or any group of persons
including Participant); 

        (iii)    consummation
of a merger, consolidation, statutory share exchange or similar form of corporate transaction involving the Company or any of its Subsidiary Companies, (a
"Business Combination"), unless immediately following such Business Combination: (A) more than 60% of the total voting power of (x) the
corporation resulting from such Business Combination (the "Surviving Corporation"), or (y) if applicable, the ultimate parent corporation that
directly or indirectly has beneficial ownership of at least 95% of the voting securities eligible to elect directors of the Surviving Corporation (the "Parent
Corporation"), is represented by Company Voting Securities that were outstanding immediately prior to such Business Combination (or, if applicable, is represented by shares
into which such Company Voting Securities were converted pursuant to such Business Combination), and such voting power among the holders thereof is in substantially the same proportion as the voting
power of such Company Voting Securities among the holders thereof immediately prior to the Business Combination, (B) no person (other than any employee benefit plan (or related trust) sponsored
or maintained by the Surviving Corporation or the Parent Corporation), is or becomes the beneficial owner, directly or indirectly, of 20% or more of the total voting power of the outstanding voting
securities eligible to elect directors of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation) and (C) at least a majority of the members of the board of
directors of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation) following the consummation of the Business Combination were Incumbent Directors at the time of
the Board's approval of the execution of the initial agreement providing for such Business Combination (any Business Combination which satisfies all of the criteria specified in (A), (B), and
(C) above shall be deemed to be a "Non-Qualifying Transaction"); or 

        (iv)    the
stockholders of the Company approve a plan of complete liquidation or dissolution of the Company, or the consummation of a sale of all or substantially all of the
Company's assets. 

Notwithstanding
the foregoing, a Change in Control of the Company shall not be deemed to occur solely because any person acquires beneficial ownership of more than 20% of the Company Voting Securities
as a result of the acquisition of Company Voting Securities by the Company which reduces the number of Company Voting Securities outstanding; provided,
that if after such acquisition by the Company such person becomes the beneficial owner of additional Company Voting Securities that increases the percentage of outstanding
Company Voting Securities beneficially owned by such person, a Change in Control of the Company shall then occur. 

        B.    Amount of Award Subject to Accelerated Payout/Option Period/Exercise Period.    The amount of a Participant's
previously granted Award that will be paid or exercisable upon the happening of a change in control will be determined as follows: 

        Service-Based Restricted Stock or Restricted Stock Unit Awards.    The Participant will be entitled to an accelerated Award
payout, and the amount of the payout will be based on the number of shares of Service-Based Restricted Stock or Restricted Stock Units that were issued on the Date of Grant. 

        Stock Option Awards and Stock Appreciation Rights.    Any previously granted Stock Option Awards or Stock Appreciation Rights
will be immediately vested, any gain will be immediately paid in cash, and the Stock Option Awards and/or Stock Appreciation Rights will then lapse. 

10

 

        Performance-Based Restricted Stock or Restricted Stock Units/Performance Units.    The Participant will be entitled to an
accelerated Award payout, and the amount of the payout will be based on the number of shares of Performance-Based Restricted Stock or Restricted Stock Units/Performance Units subject to the Award as
established on the Date of Grant, prorated based on the number of months of the Performance Period that have elapsed as of the payout date, and assuming that maximum performance was achieved. 

        Equity Awards.    Any previously granted Equity Award will be immediately vested. 

        C.    Timing of Accelerated Payout/Option Period/Exercise Period.    The accelerated payout set forth in
Section 13B will be made in cash within 30 days after the date of the change in control. When Stock is
related to the Award, the amount of cash will be determined based on the Fair Market Value of Stock on the payout date. 

        14.    Amendment of Plan.

        The
Plan Administrator may at any time and from time to time alter, amend, suspend or terminate the Plan in whole or in part, except no such action may be taken without the consent of
the Participant to whom any Award was previously granted, which adversely affects the rights of such Participant concerning such Award, except as such termination or amendment of the Plan is required
by statute, or rules and regulations promulgated thereunder. 

        15.    Miscellaneous Provisions.

        A.    Nontransferability.    No benefit provided under this Plan shall be subject to alienation or assignment by a
Participant (or by any person entitled to such benefit pursuant to the terms of this Plan), nor shall it be subject to attachment or other legal process except (i) to the extent specifically
mandated and directed by applicable state or federal statute; (ii) as requested by the Participant (or by any person entitled to such benefit pursuant to the terms of this Plan), and approved
by the Plan Administrator, to satisfy income tax withholding; and (iii) as requested by the Participant and approved by the Plan Administrator, to members of the Participant's family, or a
trust established by the Participant for the benefit of family members. 

        B.    No Employment Right.    Participation in this Plan shall not constitute a contract of employment between the
Company or any Subsidiary and any person and shall not be deemed to be consideration for, or a condition of, continued employment of any person. 

        C.    Tax Withholding.    the Company or a Subsidiary may withhold any applicable federal, state or local taxes at
such time and upon such terms and conditions as required by law or determined by the Company or a Subsidiary. Subject to compliance with any requirements of applicable law, the Plan Administrator may
permit or require a Participant to have any portion of any withholding or other taxes payable in respect to a distribution of Stock satisfied through the payment of cash by the Participant to the
Company or a Subsidiary, the retention by the Company or a Subsidiary of shares of Stock, or delivery of previously owned shares of the Participant's Stock, having a Fair Market Value equal to the
withholding amount. 

        D.    Fractional Shares.    Any fractional shares concerning Awards shall be eliminated at the time of payment or
payout by rounding down for fractions of less than one-half and rounding up for fractions of equal to or more than one-half. No cash settlements shall be made with respect to
fractional shares eliminated by rounding. 

        E.    Government and Other Regulations.    The obligation of the Company to make payment of Awards in Stock or
otherwise shall be subject to all applicable laws, rules, and regulations, and to such approvals by any government agencies as may be required. The Company shall be under no obligation to register
under the Securities Act of 1933, as amended ("Act"), any of the shares of Stock issued, delivered or paid in settlement under the Plan. If Stock awarded under the Plan may in certain 

11

 

circumstances
be exempt from registration under the Act, the Company may restrict its transfer in such manner as it deems advisable to ensure such exempt status. 

        F.    Indemnification.    The Plan Administrator (and his/her designees) shall be indemnified and held harmless by the
Company against and from (i) any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by such person in connection with or resulting from any claim, action, suit,
or proceeding to which such person may be a party or in which such person may be involved by reason of any action or failure to act under the Plan; and (ii) any and all amounts paid by such
person in satisfaction of judgment in any such action, suit, or proceeding relating to the Plan. Each person covered by this indemnification shall give the Company an opportunity, at its own expense,
to handle and defend the same before such person undertakes to handle and defend it on such person's own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of
indemnification to which such persons may be entitled under the Charter or By-Laws of the Company or any of its Subsidiaries, as a matter of law, or otherwise, or any power that the
Company may have to indemnify such person or hold such person harmless. 

        G.    Reliance on Reports.    The Plan Administrator (and each person to whom the Plan Administrator has delegated any
of his/her authority or power under this Plan) shall be fully justified in relying or acting in good faith upon any report made by the independent public accountants of the Company and its
Subsidiaries and upon any other information furnished in connection with the Plan. In no event shall the Plan Administrator (or each person to whom the Plan Administrator has delegated any of his/her
authority or power under this Plan) be liable for any determination made or other action taken or any omission to act in reliance upon any such report or information or for any action taken, including
the furnishing of information, or failure to act, if in good faith. 

        H.    Changes in Capital Structure.    In the event of any change in the outstanding shares of Stock by reason of any
stock dividend or split, recapitalization, combination or exchange of shares or other similar changes in the Stock, then appropriate adjustments shall be made in the shares of Stock theretofore
awarded to the Participants and in the aggregate number of shares of Stock which may be awarded pursuant to the Plan. Such adjustments shall be conclusive and binding for all purposes. Additional
shares of Stock issued to a Participant as the result of any such change shall bear the same restrictions as the shares of Stock to which they relate. 

        I.    Company Successors.    In the event the Company becomes a party to a merger, consolidation, sale of
substantially all of its assets or any other corporate reorganization in which the Company will not be
the surviving corporation or in which the holders of the Stock will receive securities of another corporation (in any such case, the "New Company"), then the New Company shall assume the rights and
obligations of the Company under this Plan. 

        J.    Governing Law.    All matters relating to the Plan or to Awards granted hereunder shall be governed by the laws
of the State of Maryland, without regard to the principles of conflict of laws. 

        K.    Relationship to Other Benefits.    Any Awards under this Plan are not considered compensation for purposes of
determining benefits under any pension, profit sharing, or other retirement or welfare plan, or for any other general employee benefit program. 

        L.    Expenses.    The expenses of administering the Plan shall be borne by the Company and its Subsidiaries. 

12

 

        M.    Titles and Headings.    The titles and headings of the sections in the Plan are for convenience of reference
only, and in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control.

sole authority (except as specified otherwise herein) to determine all questions of interpretation and application of the Plan, or of the terms and conditions pursuant to which Awards are granted,

legend prohibiting sale, transfer, pledge or hypothecation of the Restricted Stock or Restricted Stock Unit until the expiration of the restriction period. 

3

 

        The
Plan Administrator may also impose such other restrictions and conditions on the Restricted Stock or Restricted Stock Unit as it deems appropriate, and will designate the grant as
either a Service-Based or Performance-Based Award. 

        Upon
issuance to the Participant of the Restricted Stock, the Participant will have the right to vote the Restricted Stock. Upon issuance to the Participant of the Restricted Stock or
grant of the Restricted Stock Unit and subject to the Plan Administrator's discretion, the Participant will have the right to receive the cash dividends (or Dividend Equivalents as provided in
Section 11) distributable with respect to such shares or units, with such dividends or Dividend Equivalents treated as compensation to the Participant. The Plan Administrator, in his/her sole
discretion, may direct the accumulation and payment of distributable dividends to the Participant at such times, and in such form and manner, as determined by the Plan Administrator. 

        B.    Service-Based Award.

        i.    Restriction Period.    At the time a Service-Based Restricted Stock or Restricted Stock Unit Award is granted,
the Plan Administrator will establish a restriction period applicable to such Award which will be not less than one year and not more than ten years. Each Restricted Stock or Restricted Stock Unit
Award may have a different restriction period, at the discretion of the Plan Administrator. 

        ii.    Forfeiture or Payout of Award.    In the event a Participant ceases employment during a restriction period, a
Restricted Stock or Restricted Stock Unit Award is subject to forfeiture or payout (i.e., removal of restrictions) as follows: (a) Termination—the Restricted Stock or Restricted
Stock Unit Award is completely forfeited; (b) Retirement, Disability or death—payout of the Restricted Stock or Restricted Stock Unit Award is prorated for service during the
period; or (c) Early Retirement—if at the Participant's request, the payout or forfeiture of the Restricted Stock or Restricted Stock Unit Award is determined at the discretion of
the Plan Administrator, or if at Constellation Energy's request, payout of the Restricted Stock or Restricted Stock Unit Award is prorated for service during the period; provided, however, that the
Plan Administrator may modify the above if it determines at his/her sole discretion that special circumstances warrant such modification. 

        Any
shares of Restricted Stock which are forfeited will be transferred to Constellation Energy. 

        Upon
completion of the restriction period, all Award restrictions will expire and certificates representing the Award will be issued (the payout) without the restrictive legend described
in Section 7A. 

        C.    Performance-Based Award.

        i.    Restriction Period.    At the time a Performance-Based Restricted Stock or Restricted Stock Unit Award is
granted, the Plan Administrator will establish a restriction period applicable to such Award which will be not less than one year and not more than ten years. Each Restricted Stock or Restricted Stock
Unit Award may have a different restriction period, at the discretion of the Plan Administrator. The Plan Administrator will also establish a Performance Period. 

        ii.    Performance Objectives.    The Plan Administrator will determine, no later than 90 days after the
beginning of each Performance Period, the performance objectives for each Participant's Target Performance Award and the number of shares of Restricted Stock or Restricted Stock Units for each Target
Performance Award that will be issued on the Date of Grant. Performance objectives may vary from Participant to Participant and will be based upon such performance criteria or combination of factors
as the Plan Administrator deems appropriate, which may include, but not be limited to, the performance of the Participant, Constellation Energy, one or more Subsidiaries, or any combination thereof.
Performance Periods may overlap and Participants may 

4

 

participate
simultaneously with respect to Performance-Based Restricted Stock or Restricted Stock Unit Awards for which different Performance Periods are prescribed. 

        If,
during the course of a Performance Period significant events occur as determined in the sole discretion of the Plan Administrator, which the Plan Administrator expects to have a
substantial effect on a performance objective during such period, the Plan Administrator may revise such objective. 

        iii.    Forfeiture or Payout of Award.    As soon as practicable after the end of each Performance Period, the Plan
Administrator will determine whether the performance objectives and other material terms of the Award were satisfied. The Plan Administrator's determination of all such matters will be final and
conclusive. 

        As
soon as practicable after the later of (i) the date the Plan Administrator makes the above determination, or (ii) the completion of the restriction period, the Plan
Administrator will determine the Earned Performance Award for each Participant. Such determination may result in forfeiture of all or some shares of Restricted Stock or Restricted Stock Units (if
Target Performance Award performance objectives were not attained), or the issuance of additional shares of Stock or Restricted Stock Units (if Target Performance Award performance objectives were
exceeded), and will be based upon such factors as the Plan Administrator determines at his/her sole discretion, but including the Target Performance Award performance objectives. 

        In
the event a Participant ceases employment during a restriction period, the Restricted Stock or Restricted Stock Unit Award is subject to forfeiture or payout (i.e., removal of
restrictions) as follows: (a) Termination—the Restricted Stock or Restricted Stock Unit Award is completely forfeited; (b) Retirement, Disability or death—payout
of the Restricted Stock or Restricted Stock Unit Award is prorated taking into account factors including, but not limited to, service during the period; and the performance of the Participant during
the portion of the Performance Period before employment ceased; or (c) Early Retirement—if at the Participant's request, the payout or forfeiture of the Restricted Stock or
Restricted Stock Unit Award is determined at the discretion of the Plan Administrator, or if at Constellation Energy's request, payout of the Restricted Stock or Restricted Stock Unit Award is
prorated taking into account factors including, but not limited to, service during the period and the performance of the Participant during the portion of the Performance Period before employment
ceased; provided, however, that the Plan Administrator may
modify the above if it determines at his/her sole discretion that special circumstances warrant such modification. 

        Any
shares of Restricted Stock which are forfeited will be transferred to Constellation Energy. 

        With
respect to shares of Restricted Stock or Restricted Stock Units for which restrictions lapse, certificates will be issued (the payout) without the restrictive legend described in
Section 7A. Certificates will also be issued for additional Stock, if any, awarded to the Participant because Target Performance Award performance objectives were exceeded. 

        D.    Waiver of Section 83(b) Election.    Unless otherwise directed by the Plan Administrator, as a condition
of receiving an Award of Restricted Stock, a Participant must waive in writing the right to make an election under Section 83(b) of the Code to report the value of the Restricted Stock as
income on the Date of Grant. 

        8.    Stock Options

        A.    Grants of Options.    One or more Options may be granted to any Eligible Employee on the Date of Grant without
the payment of consideration by the Participant. 

        B.    Stock Option Agreement.    Each Option granted under the Plan will be evidenced by a "Stock Option Agreement"
between Constellation Energy and the Participant containing provisions determined by the Plan Administrator, including, without limitation, provisions to qualify Incentive Stock Options 

5

 

as
such under Section 422 of the Code if directed by the Plan Administrator at the Date of Grant; provided, however, that each Incentive Stock Option Agreement must include the following terms
and conditions: (i) that the Options are exercisable, either in total or in part, with a partial exercise not affecting the exercisability of the balance of the Option; (ii) every share
of Stock purchased through the exercise of an Option will be paid for in full at the time of the exercise; (iii) each Option will cease to be exercisable, as to any share of Stock, at the
earliest of (a) the Participant's purchase of the Stock to which the Option relates, (b) the Participant's exercise of a related Stock Appreciation Right, or (c) the lapse of the
Option; (iv) Options will not be transferable by the Participant except by Will or the laws of descent and distribution and will be exercisable during the Participant's lifetime only by the
Participant or by the Participant's guardian or legal representative; and (v) notwithstanding any other provision, in the event of a public tender for all or any portion of the Stock or in the
event that any proposal to merge or consolidate Constellation Energy with another company is submitted to the stockholders of Constellation Energy for a vote, the Plan Administrator, in his\her sole
discretion, may declare any previously granted Option to be immediately exercisable. 

        C.    Option Price.    The Option price per share of Stock will be set by the grant, but will be not less than 100% of
the Fair Market Value at the Date of Grant. 

        D.    Form of Payment.    At the time of the exercise of the Option, the Option price will be payable in cash or in
other shares of Stock or in a combination of cash and other shares of Stock, in a form and manner as required by the Plan Administrator in his/her sole discretion. When Stock is used in full or
partial payment of the Option price, it will be valued at the Fair Market Value on the date the Option is exercised. 

        E.    Other Terms and Conditions.    The Option will become exercisable in such manner and within such Option Period
or Periods, not to exceed 10 years from its Date of Grant, as set forth in the Stock Option Agreement upon payment in full. Except as otherwise provided in this Plan or in the Stock Option
Agreement, any Option may be exercised in whole or in part at any time. 

        F.    Lapse of Option.    An Option will lapse upon the earlier of: (i) 10 years from the Date of Grant,
or (ii) at the expiration of the Option Period set by the grant. If the Participant ceases employment within the Option Period and prior to the lapse of the Option, the Option will lapse as
follows: (a) Termination—the Option will lapse on the effective date of the Termination; or (b) Retirement, Early Retirement, or Disability—the Option will lapse
at the expiration of the Option Period set by the grant; provided, however, that the Plan Administrator may modify the above if he/she determines in his/her sole discretion that special circumstances
warrant such modification. If the Participant dies within the Option Period and prior to the lapse of the Option, the Option will lapse at the expiration of the Option Period set by the grant unless
it is exercised before such time by the Participant's legal representative(s) or by the person(s) entitled to do so under the Participant's Will or, if the Participant fails to make testamentary
disposition of the Option or dies intestate, by the person(s) entitled to receive the Option under the applicable laws of descent and distribution. 

        G.    Individual Limitation.    In the case of an Incentive Stock Option, the aggregate Fair Market Value of the Stock
for which Incentive Stock Options (whether under this Plan or another arrangement) in any calendar year are first exercisable will not exceed $100,000 with respect to such calendar year (or such other
individual limit as may be in effect under the Code on the Date of Grant) plus any unused portion of such limit as the Code may permit to be carried over. 

        9.    Performance Units.

        A.    Performance Units.    One or more Performance Units may be earned by an Eligible Employee based on the
achievement of preestablished performance objectives during a Performance Period. 

        B.    Performance Period and Performance Objectives.    The Plan Administrator will determine a Performance Period and
will determine, no later than 90 days after the beginning of each Performance 

6

 

Period,
the performance objectives for each Participant's Target Performance Award and the number of Performance Units subject to each Target Performance Award. Performance objectives may vary from
Participant to Participant and will be based upon such performance criteria or combination of factors as the Plan Administrator deems appropriate, which may include, but not be limited to, the
performance of the Participant, Constellation Energy, one or more Subsidiaries, or any combination thereof. Performance Periods may overlap and Participants may participate simultaneously with respect
to Performance Units for which different Performance Periods are prescribed. 

        If
during the course of a Performance Period significant events occur as determined in the sole discretion of the Plan Administrator which the Plan Administrator expects to have a
substantial effect on a performance objective during such period, the Plan Administrator may revise such objective. 

        C.    Forfeiture or Payout of Award.    As soon as practicable after the end of each Performance Period, the Plan
Administrator will determine whether the performance objectives and other material terms of the Award were satisfied. The Plan Administrator's determination of all such matters will be final and
conclusive. 

        As
soon as practicable after the date the Plan Administrator makes the above determination, the Plan Administrator will determine the Earned Performance Award for each Participant. Such
determination may result in an increase or decrease in the number of Performance Units payable based upon such Participant's Target Performance Award, and will be based upon such factors as the Plan
Administrator determines in his/her sole discretion, but including the Target Performance Award performance objectives. 

        In
the event a Participant ceases employment during a Performance Period, the Performance Unit Award is subject to forfeiture or payout as follows: (a) Termination—the
Performance Unit Award is completely forfeited; (b) Retirement, Disability or death—payout of the Performance Unit Award is prorated taking into account factors including, but not
limited to, service and the performance of the Participant during the portion of the Performance Period before employment ceased; or (c) Early Retirement—if at the Participant's
request, the payout or forfeiture of the Performance Unit Award is determined at the discretion of the Plan Administrator, or if at Constellation Energy's request, payout of the Performance Unit Award
is prorated taking into account factors including, but not limited to, service and the performance of the Participant during the portion of the Performance Period before employment ceased; provided,
however, that the Plan Administrator may modify the above if it determines in his/her sole discretion that special circumstances warrant such modification. 

        D.    Form and Timing of Payment.    Each Performance Unit is payable in cash or shares of Stock or in a combination
of cash and Stock, as determined by the Plan Administrator in his/her sole discretion. Such payment will be made as soon as practicable after the Earned Performance Award is determined. 

        10.    Stock Appreciation Rights.

        A.    Grants of Stock Appreciation Rights.    Stock Appreciation Rights may be granted under the Plan in conjunction
with an Option either at the Date of Grant or by amendment or may be separately granted. Stock Appreciation Rights will be subject to such terms and conditions not inconsistent with the Plan as the
Plan Administrator may impose. 

        B.    Right to Exercise; Exercise Period.    A Stock Appreciation Right issued pursuant to an Option will be
exercisable to the extent the Option is exercisable; both such Stock Appreciation Right and the Option to which it relates will not be exercisable during the six months following their respective
Dates of Grant except in the event of the Participant's Disability or death. A Stock Appreciation Right issued independent of an Option will be exercisable pursuant to such terms and conditions
established in the grant. Notwithstanding such terms and conditions, in the event of a public tender for all or any portion of the Stock or in the event that any proposal to merge or consolidate
Constellation Energy with 

7

 

another
company is submitted to the stockholders of Constellation Energy for a vote, the Plan Administrator, in his/her sole discretion, may declare any previously granted Stock Appreciation Right
immediately exercisable. 

        C.    Failure to Exercise.    If on the last day of the Option Period, in the case of a Stock Appreciation Right
granted pursuant to an Option, or the specified Exercise Period, in the case of a Stock Appreciation Right issued independent of an Option, the Participant has not exercised a Stock Appreciation
Right, then such Stock Appreciation Right will be deemed to have been exercised by the Participant on the last day of the Option Period or Exercise Period. 

        D.    Payment.    An exercisable Stock Appreciation Right granted pursuant to an Option will entitle the Participant
to surrender unexercised the Option or any portion thereof to which the Stock Appreciation Right is attached, and to receive in exchange for the Stock Appreciation Right payment (in cash or Stock or a
combination thereof as described below) equal to either of the following amounts, determined in the sole discretion of the Plan Administrator at the Date of Grant: (1) the excess of the Fair
Market Value of one share of Stock at the date of exercise over the Option price, times the number of shares called for by the Stock Appreciation Right (or portion thereof) which is so surrendered, or
(2) the excess of the Book Value of one share of Stock at the date of exercise over the Book Value of one share of Stock at the Date of Grant of the related Option, times the number of shares
called for by the Stock Appreciation Right. Upon exercise of a Stock Appreciation Right not
granted pursuant to an Option, the Participant will receive for each Stock Appreciation Right payment (in cash or Stock or a combination thereof as described below) equal to either of the following
amounts, determined in the sole discretion of the Plan Administrator at the Date of Grant: (1) the excess of the Fair Market Value of one share of Stock at the date of exercise over the Fair
Market Value of one share of Stock at the Date of Grant of the Stock Appreciation Right, times the number of shares called for by the Stock Appreciation Right, or (2) the excess of the Book
Value of one share of Stock at the date of exercise of the Stock Appreciation Right over the Book Value of one share of Stock at the Date of Grant of the Stock Appreciation Right, times the number of
shares called for by the Stock Appreciation Right. 

        The
Plan Administrator may direct the payment in settlement of the Stock Appreciation Right to be in cash or Stock or a combination thereof. Alternatively, the Plan Administrator may
permit the Participant to elect to receive cash in full or partial settlement of the Stock Appreciation Right, provided that (i) the Plan Administrator must consent to or disapprove such
election and (ii) unless the Plan Administrator directs otherwise, the election and the exercise must be made during the period beginning on the 3rd business day following the date of public
release of quarterly or year-end earnings and ending on the 12th business day following the date of public release of quarterly or year-end earnings. The value of the Stock to
be received upon exercise of a Stock Appreciation Right shall be the Fair Market Value of the Stock on the trading day preceding the date on which the Stock Appreciation Right is exercised. To the
extent that a Stock Appreciation Right issued pursuant to an Option is exercised, such Option shall be deemed to have been exercised, and shall not be deemed to have lapsed. 

        E.    Nontransferable.    A Stock Appreciation Right will not be transferable by the Participant except by Will or the
laws of descent and distribution and will be exercisable during the Participant's lifetime only by the Participant or by the Participant's guardian or legal representative. 

        F.    Lapse of a Stock Appreciation Right.    A Stock Appreciation Right will lapse upon the earlier of:
(i) 10 years from the Date of Grant; or (ii) at the expiration of the Exercise Period as set by the grant. If the Participant ceases employment within the Exercise Period and
prior to the lapse of the Stock Appreciation Right, the Stock Appreciation Right will lapse as follows: (a) Termination—the Stock Appreciation Right will lapse on the effective date
of the Termination; or (b) Retirement, Early Retirement, or Disability—the Stock Appreciation Right will lapse at the expiration of the Exercise 

8

 

Period
set by the grant; provided, however, that the Plan Administrator may modify the above if he/she determines in his/her sole discretion that special circumstances warrant such modification. If
the Participant dies within the Exercise Period and prior to the lapse of the Stock Appreciation Right, the Stock Appreciation Right will lapse at the expiration of the Exercise Period set by the
grant unless it is exercised before such time by the Participant's legal representative(s) or by the person(s) entitled to do so under the Participant's Will or, if the Participant fails to make
testamentary disposition of the Stock Appreciation Right or dies intestate, by the person(s) entitled to receive the Stock Appreciation Right under the applicable laws of descent and distribution. 

        11.    Dividend Equivalents.

        A.    Grants of Dividend Equivalents.    Dividend Equivalents may be granted under the Plan in conjunction with an
Option or a separately awarded Stock Appreciation Right, at the Date of Grant or by amendment, without consideration by the Participant. Dividend Equivalents may also be granted under the Plan in
conjunction with Performance Units, at any time during the Performance Period, without consideration by the Participant. Dividend Equivalents will be granted under a Performance-Based Restricted Stock
or Restricted Stock Unit Award in conjunction with additional shares of Stock issued if Target Performance Award performance objectives are exceeded. 

        B.    Payment.    Each Dividend Equivalent will entitle the Participant to receive an amount equal to the dividend
actually paid with respect to a share of Stock on each dividend payment date from the Date of Grant to the date the Dividend Equivalent lapses as set forth in Section 11D. The Plan
Administrator, in his/her sole discretion, may direct the payment of such amount at such times and in such form and manner as determined by the Plan Administrator. 

        C.    Nontransferable.    A Dividend Equivalent will not be transferable by the Participant. 

        D.    Lapse of a Dividend Equivalent.    Each Dividend Equivalent will lapse on the earlier of (i) the date of
the lapse of the related Option or Stock Appreciation Right; (ii) the date of the exercise of the related Option or Stock Appreciation Right; (iii) the end of the Performance Period (or
if earlier, the date the Participant ceases employment) of the related Performance Units or Performance-Based Restricted Stock or Restricted Stock Unit Award; or (iv) the lapse date established
by the Plan Administrator on the Date of Grant of the Dividend Equivalent. 

        12.    Accelerated Award Payout/Exercise.

        A.    Change in Control.    Notwithstanding anything in this Plan document to the contrary, a Participant is entitled
to an accelerated payout or accelerated Option or Exercise Period (as set forth in Section 12B) with respect to any previously granted Award, upon the happening of a change in control. 

        A
change in control for purposes of this Section 12 means the occurrence of any one of the following events: 

        (i)    individuals
who, on January 24, 2003, constitute the Board (the "Incumbent Directors") cease for any reason to
constitute at least a majority of the Board, provided that any person becoming a director subsequent to January 24, 2003, whose election or nomination for election was approved by a vote of at
least two-thirds of the Incumbent Directors then on the Board (either by a specific vote or by approval of the proxy statement of Constellation Energy Group (the
"Company") in which such person is named as a nominee for director, without written objection to such nomination) shall be an Incumbent Director;  provided, however, that no individual initially elected or nominated as a director of the Company as a result of an actual or threatened election
contest with respect to directors or as a result of any other actual or threatened solicitation of proxies by or on behalf of any person other than the Board shall be deemed to be an Incumbent
Director; 

9

 

        (ii)    any
"person" (as such term is defined in Section 3(a)(9) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act") and as used in Sections 13(d)(3) and 14(d)(2) of the Exchange Act) is or becomes a "beneficial owner" (as defined in Rule 13d-3 under the Exchange
Act), directly or indirectly, of securities of the Company representing 20% or more of the combined voting power of the Company's then outstanding securities eligible to vote for the election of the
Board (the "Company Voting Securities"); provided, however, that the event described in this
paragraph (ii) shall not be deemed to be a Change in Control by virtue of any of the following acquisitions: (A) by the Company or any corporation with respect to which the Company owns
a majority of the outstanding shares of common stock or has the power to vote or direct the voting of sufficient securities to elect a majority of the directors (a "Subsidiary
Company"), (B) by any employee benefit plan (or related trust) sponsored or maintained by the Company or any Subsidiary Company, (C) by any underwriter
temporarily holding securities pursuant to an offering of such securities, (D) pursuant to a Non-Qualifying Transaction (as defined in paragraph (iii)), or
(E) pursuant to any acquisition by Participant or any group of persons including Participant (or any entity controlled by Participant or any group of persons including Participant); 

        (iii)    consummation
of a merger, consolidation, statutory share exchange or similar form of corporate transaction involving the Company or any of its Subsidiary Companies, (a
"Business Combination"), unless immediately following such Business Combination: (A) more than 60% of the total voting power of (x) the
corporation resulting from such Business Combination (the "Surviving Corporation"), or (y) if applicable, the ultimate parent corporation that
directly or indirectly has beneficial ownership of at least 95% of the voting securities eligible to elect directors of the Surviving Corporation (the "Parent
Corporation"), is represented by Company Voting Securities that were outstanding immediately prior to such Business Combination (or, if applicable, is represented by shares
into which such Company Voting Securities were converted pursuant to such Business Combination), and such voting power among the holders thereof is in substantially the same proportion as the voting
power of such Company Voting Securities among the holders thereof immediately prior to the Business Combination, (B) no person (other than any employee benefit plan (or related trust) sponsored
or maintained by the Surviving Corporation or the Parent Corporation), is or becomes the beneficial owner, directly or indirectly, of 20% or more of the total voting power of the outstanding voting
securities eligible to elect directors of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation) and (C) at least a majority of the members of the board of
directors of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation) following the consummation of the Business Combination were Incumbent Directors at the time of
the Board's approval of the execution of the
initial agreement providing for such Business Combination (any Business Combination which satisfies all of the criteria specified in (A), (B), and (C) above shall be deemed to be a
"Non-Qualifying Transaction"); or 

        (iv)    the
stockholders of the Company approve a plan of complete liquidation or dissolution of the Company, or the consummation of a sale of all or substantially all of the
Company's assets. 

Notwithstanding
the foregoing, a Change in Control of the Company shall not be deemed to occur solely because any person acquires beneficial ownership of more than 20% of the Company Voting Securities
as a result of the acquisition of Company Voting Securities by the Company which reduces the number of Company Voting Securities outstanding; provided,
that if after such acquisition by the Company such person becomes the beneficial owner of additional Company Voting Securities that increases the percentage of outstanding
Company Voting Securities beneficially owned by such person, a Change in Control of the Company shall then occur. 

10

 

        B.    Amount of Award Subject to Accelerated Payout/Option Period/Exercise Period.    The amount of a Participant's
previously granted Award that will be paid or exercisable upon the happening of a change in control will be determined as follows: 

        Restricted Stock or Restricted Stock Unit Awards.    The Participant will be entitled to an accelerated Award payout, and the
amount of the payout will be based on the number of shares of Restricted Stock or Restricted Stock Units that were issued on the Date of Grant, prorated based on the number of months of the
restriction period that have elapsed as of the payout date. Also, with respect to Performance-Based Restricted Stock or Restricted Stock Unit Awards, in determining the amount of the payout, maximum
performance achievement will be assumed. 

        Stock Option Awards and Stock Appreciation Rights.    Any previously granted Stock Option Awards or Stock Appreciation Rights
will be immediately exercisable. 

        Performance Units.    The Participant will be entitled to an accelerated Award payout, and the amount of the payout will be
based on the number of Performance Units subject to the Target Performance Award as established on the Date of Grant, prorated based on the number of months of the Performance Period that have elapsed
as of the payout date, and assuming that maximum performance was achieved. 

        C.    Timing of Accelerated Payout/Option Period/Exercise Period.    The accelerated payout set forth in
Section 12B will be made in cash within 30 days after the date of the change in control. The accelerated Option Period/Exercise Period set forth in Section 12B will begin on the
date of the change in control, and applicable payments will be in cash. When Stock is related to the Award, the amount of cash will be determined based on the Fair Market Value of Stock on the payout
or exercise date, whichever is applicable. 

        13.    Amendment of Plan.

        The
Plan Administrator may at any time and from time to time alter, amend, suspend or terminate the Plan in whole or in part, except no such action may be taken without the consent of
the Participant to whom any Award was previously granted, which adversely affects the rights of such Participant concerning such Award, except as such termination or amendment of the Plan is required
by statute, or rules and regulations promulgated thereunder. 

        14.    Miscellaneous Provisions.

        A.    Nontransferability.    No benefit provided under this Plan shall be subject to alienation or assignment by a
Participant (or by any person entitled to such benefit pursuant to the terms of this Plan), nor shall it be subject to attachment or other legal process except (i) to the extent specifically
mandated and directed by applicable state or federal statute, (ii) as requested by the Participant (or by any person entitled to such benefit pursuant to the terms of this Plan), and approved
by the Plan Administrator, to satisfy income tax withholding, and (iii) as requested by the Participant and approved by the Plan Administrator, to members of the Participant's family, or a
trust established by the Participant for the benefit of family members. 

        B.    No Employment Right.    Participation in this Plan shall not constitute a contract of employment between
Constellation Energy or any Subsidiary and any person and shall not be deemed to be consideration for, or a condition of, continued employment of any person. 

        C.    Tax Withholding.    Constellation Energy or a Subsidiary may withhold any applicable federal, state or local
taxes at such time and upon such terms and conditions as required by law or determined by Constellation Energy or a Subsidiary. Subject to compliance with any requirements of applicable law, the Plan
Administrator may permit or require a Participant to have any portion of any withholding or other taxes payable in respect to a distribution of Stock satisfied through the payment of cash by the 

11

 

Participant
to Constellation Energy or a Subsidiary, the retention by Constellation Energy or a Subsidiary of shares of Stock, or delivery of previously owned shares of the Participant's Stock, having
a Fair Market Value equal to the withholding amount. 

        D.    Fractional Shares.    Any fractional shares concerning Awards shall be eliminated at the time of payment or
payout by rounding down for fractions of less than one-half and rounding up for fractions of equal to or more than one-half. No cash settlements shall be made with respect to
fractional shares eliminated by rounding. 

        E.    Government and Other Regulations.    The obligation of Constellation Energy to make payment of Awards in Stock
or otherwise shall be subject to all applicable laws, rules, and regulations, and to such approvals by any government agencies as may be required. Constellation Energy shall be under no obligation to
register under the Securities Act of 1933, as amended ("Act"), any of the shares of Stock issued, delivered or paid in settlement under the Plan. If Stock awarded under the Plan may in certain
circumstances be exempt from registration under the Act, Constellation Energy may restrict its transfer in such manner as it deems advisable to ensure such exempt status. The Plan is not subject to
any provisions of the Employee Retirement Income Security Act of 1974. 

        F.    Indemnification.    The Plan Administrator (and his/her designees), and Constellation Energy's Chairman of the
Board, and President and all other employees of Constellation Energy or its Subsidiaries whose assigned duties include matters under the Plan, shall be indemnified by Constellation Energy or its
Subsidiaries or from proceeds under insurance policies purchased by Constellation Energy or its Subsidiaries against any and all liabilities arising by reason of any act or failure to act made in good
faith pursuant to the provisions of the Plan, including expenses reasonably incurred in the defense of any related claim. 

        G.    Changes in Capital Structure.    In the event of any change in the outstanding shares of Stock by reason of any
stock dividend or split, recapitalization, combination or exchange of shares or other similar changes in the Stock, then appropriate adjustments shall be made in the shares of Stock theretofore
awarded to the Participants and in the aggregate number of shares of Stock which may be awarded pursuant to the Plan. Such adjustments shall be conclusive and binding for all purposes. Additional
shares of Stock issued as the result of any such change shall bear the same restrictions as the shares of Stock to which they relate. 

        H.    Constellation Energy Successors.    In the event Constellation Energy becomes a party to a merger,
consolidation, sale of substantially all of its assets or any other corporate reorganization in which Constellation Energy will not be the surviving corporation or in which the holders of the Stock
will receive securities of another corporation (in any such case, the "New Company"), then the New Company shall assume the rights and obligations of Constellation Energy under this Plan. 

        I.    Governing Law.    All matters relating to the Plan or to Awards granted hereunder shall be governed by the laws
of the State of Maryland, without regard to the principles of conflict of laws. 

        J.    Relationship to Other Benefits.    Any Awards under this Plan are not considered compensation for purposes of
determining benefits under any pension, profit sharing, or other retirement or welfare plan, or for any other general employee benefit program. 

        K.    Expenses.    The expenses of administering the Plan shall be borne by Constellation Energy and its Subsidiaries. 

12

 

        L.    Titles and Headings.    The titles and headings of the sections in the Plan are for convenience of reference
only, and in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control.
