<P><FONT SIZE=2>Set
forth is a brief overview of certain income tax consequences associated with your Service-Based Restricted Stock Award ("the Award"). </FONT></P>


<P><FONT SIZE=2><I>Stock  </I></FONT></P>

<P><FONT SIZE=2>Because the Plan places certain restrictions on the Award which could lead to forfeiture of the shares prior to lifting the Plan restrictions and because you have agreed to
waive the Section&nbsp;83(b) election(1), the value of the restricted stock is not taxed to you when the initial grant is made. Rather, the stock is taxable to you at the time the restrictions are
removed. The amount subject to income tax is the fair market value of the stock on the day that the Plan restrictions are removed. This amount is treated as compensation subject to withholding of
income taxes, Medicare taxes and, if applicable, Social Security taxes. You are not taxed on the value of any stock forfeited. </FONT></P>

<P><FONT SIZE=2>For
purposes of determining the gain or loss on any sale of the stock received pursuant to this Award, your basis in the stock is the amount that you included in taxable income when the Plan
restrictions were removed. Your tax holding period, for purposes of determining whether a gain or loss on a sale is long-term or short-term, begins on the day after the day
that the Plan restrictions were removed. </FONT></P>

<P><FONT SIZE=2><I>Dividends  </I></FONT></P>

<P><FONT SIZE=2>The dividends during the restriction period will be automatically reinvested in additional shares of company common stock. These shares will be subject to the same restrictions
as the originally awarded shares and will vest accordingly. For tax
purposes, the dividends on the restricted stock will not be taxable as dividend income. Rather, the accumulated shares of stock will be taxable to you in the same manner as stated above. </FONT></P>


<P><FONT SIZE=2>After
the Plan restrictions on the stock are removed, the dividends are treated as regular dividend income (generally not subject to tax withholding). </FONT></P>

<P><FONT SIZE=2><I>Tax Planning  </I></FONT></P>

<P><FONT SIZE=2>You may wish to consult your tax advisor in the year the restrictions are lifted from the Award if you have questions regarding the impact of the Award on your tax withholding
or if you have questions about the applicable capital gains holding period and rates for this Award. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;Except
as provided in paragraph&nbsp;3(b) below, the Option will terminate upon the earlier to occur of: (1)&nbsp;when all Option Shares have been exercised; or
(2)&nbsp;ten (10)&nbsp;years from the Grant Date ("Expiration Date"). </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;If
Participant ceases employment, the Option will terminate as to any unvested Option Shares on the effective date of Participant's employment Termination (as defined in
the Plan) and as to vested Option Shares 90&nbsp;days after such effective date; provided that if Participant ceases employment because of Participant's Retirement, Disability (each as defined in
the Plan), or death, the Option will terminate as to any unvested Option Shares on the effective date of the Retirement, Disability or death, and as to vested Option Shares, the Option will remain
exercisable until the earlier of 60&nbsp;months after such effective date or the Expiration Date. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;In
the event of Participant's death during the Option Period, vested Option Shares may be exercised by Participant's legal representative(s), or by other person(s)
authorized under Participant's will. Alternatively, if Participant fails to make testamentary disposition of the Option or dies intestate, such vested Option Shares may be exercised by persons(s)
entitled to receive the Option Shares under the applicable laws of descent and distribution. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;A
transfer of Participant's employment between Constellation Energy and any Subsidiary of Constellation Energy, or between Subsidiaries of Constellation Energy, will not
be considered an employment Termination. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;Subject

or before the exercise date specified pursuant to paragraph&nbsp;4(a), Participant must fully pay the Exercise Price and the tax withholding obligation for the
Option Shares exercised in U.S. dollars by cash or by check payable to Constellation Energy Group,&nbsp;Inc. All or a portion of the Exercise Price and tax withholding obligation may also be paid by
Participant: (i)&nbsp;subject to the terms of paragraph&nbsp;4(c) below, by delivery of shares of Stock owned by Participant and acceptable to the Plan Administrator having an aggregate Fair
Market Value (as defined in paragraph&nbsp;6 below) on the date of exercise that is equal to the amount of cash that would otherwise be required; or (ii)&nbsp;by authorizing a third party to sell
the Option Shares (or a sufficient portion of the Option Shares), and immediately remit to Constellation Energy the Exercise Price and any tax withholding resulting from such exercise. Further, tax
withholding up to the minimum required withholding rate (but not in excess of that rate) may also be satisfied through a holdback by Constellation Energy of some of the Option Shares that would
otherwise be deliverable to Participant by reason of the Option exercise. The Option will cease to be exercisable, as to the portion exercised, when Participant purchases the Stock to which the
exercised portion of the Option relates. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;Other
shares of Stock owned by Participant may be delivered to satisfy the Exercise Price, or to satisfy Participant's tax withholding obligation above the minimum
withholding rate, only if the shares have been held by Participant for at least six months before delivery, except that there shall be no holding period imposed for shares purchased by Participant for
cash on the open market. Use of previously-owned shares shall be effected by actual delivery of the Stock certificates to Constellation Energy, and by completing an affidavit available from
Constellation Energy affirming that Participant owns the necessary shares and that any applicable holding period has been satisfied. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;Participant
is required to comply with Constellation Energy's Insider Trading Policy at all times, including in connection with exercise of the Option. The Option may
not be exercised by Participant during any blackout or prohibited trading period established by Constellation Energy or applicable to Participant, nor shall the Option be exercisable if and to the
extent Constellation Energy determines that such exercise would violate applicable state or Federal securities laws or the rules and regulations of any securities exchange on which the Stock is
traded. If Constellation Energy makes such a determination, it will use all reasonable efforts to comply with such laws, rules or regulations. In making any such determinations, Constellation Energy
may rely on the opinion of counsel for Constellation Energy. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;&nbsp;As
soon as practicable after the exercise date, Constellation Energy will deliver to Participant a Stock certificate or certificates (or other evidence of ownership) for
the purchased Option Shares. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Constellation Energy will have the right to withhold any applicable federal, state or local taxes, deductions or withholdings due with respect to the Option or
its exercise in such form and manner as provided in the Plan. </FONT></P>

<P><FONT SIZE=2><B>6.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Fair Market Value.  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The "Fair Market Value" of a share of Stock is the average of the highest and lowest sale price per share of Stock on the New York Stock Exchange-Composite
Transactions on the applicable date of reference, or if there are no sales on such date, then the average of such highest and lowest sale price on the last previous day on which sales are reported. </FONT></P>

<P><FONT SIZE=2><B>7.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;No Rights of Stockholders.  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Participant does not have any of the rights and privileges of a stockholder of Constellation Energy with respect to any shares of Stock purchasable or issuable
upon the exercise of the Option, in whole or in part, before the date of exercise and purchase of the Option Shares. </FONT></P>


<P><FONT SIZE=2><B>8.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Non-Transferability of Option.  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Option is not transferable, except for a transfer to Participant's family member or to a trust established for the benefit of Participant's family members
which has been approved by the Plan Administrator as provided in the Plan, or in case of Participant's death, by will or the laws of descent and distribution, nor shall the Option be subject to
attachment, execution or other similar process. During Participant's lifetime, the Option is exercisable only by Participant, any guardian or legal representative of Participant, or a family member or
trustee of a trust established for the benefit of Participant's family members to whom the Option has been transferred in accordance with the Plan. In the event of (a)&nbsp;any attempt by
Participant to alienate, assign, pledge, hypothecate or otherwise dispose of the Option, except as provided in this </FONT></P>
