<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS,
effective with the April&nbsp;30, 1999 share exchange between CEG and the common stockholders of Baltimore Gas and Electric Company
("</FONT><FONT SIZE=2><B>BGE</B></FONT><FONT SIZE=2>"), BGE transferred to CEG the former BGE Nonqualified Deferred Compensation Plan and BGE's rights and obligations under the Grantor Trust

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS,
this Agreement has been amended effective April&nbsp;25, 2003 and February&nbsp;27, 2004, to conform the definition of Change in Control under this Agreement to the
definition under CEG's management benefit plans. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS,
CEG has adopted the Constellation Energy Group,&nbsp;Inc. Nonqualified Deferred Compensation Plan (formerly the Baltimore Gas and Electric Company Nonqualified Deferred
Compensation Plan) ("</FONT><FONT SIZE=2><B>Plan</B></FONT><FONT SIZE=2>"); </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS,
CEG has incurred or expects to incur liability under the terms of such Plan with respect to the individuals participating in such Plan; </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS,
CEG wishes to establish a trust ("</FONT><FONT SIZE=2><B>Trust"</B></FONT><FONT SIZE=2>) and to contribute to the Trust assets that shall be held therein, subject to the claims
of CEG's creditors in the event of CEG's Insolvency, as defined in Section&nbsp;3(a) hereof, until paid to Plan participants and their beneficiaries in such manner and at such times as specified in
the Plan; </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS,
it is the intention of the parties that this Trust shall constitute an unfunded arrangement and shall not affect the status of the Plan as an unfunded plan maintained for the
purpose of providing deferred compensation for a select group of management or highly compensated employees for purposes of Title I of the Employee Retirement Income Security Act of 1974; </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS,
it is the intention of CEG to make contributions to the Trust to provide a source of funds to assist it in the meeting of its liabilities under the Plan; and </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NOW,
THEREFORE, the parties do hereby establish the Trust and agree that the Trust shall be comprised, held and disposed of as follows: </FONT></P>

all payments required by this Trust Agreement have been made. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;The
Trust hereby established shall be irrevocable. </FONT></P>

would otherwise have been paid, CEG shall be required to irrevocably contribute cash to the Trust in an amount equal to such Deferred Compensation, plus any Matching Contributions related thereto, to
the extent the Plan requires such funding. Trustee shall have no obligation to compute or compel such contribution(s). </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)&nbsp;&nbsp;&nbsp;&nbsp;The
Board of Directors of CEG may at any time by resolution amend the contribution requirements of Section&nbsp;1(e) hereof such that CEG will not be required to make
additional contributions of cash to the Trust or will be required to make only a stated percentage of the contributions otherwise required under Section&nbsp;1(e) hereof. If Section&nbsp;1(e) is
so amended, contributions of cash to the Trust over and above the amounts required under Section&nbsp;1(e) if amended, will be in the sole discretion of CEG pursuant to Section&nbsp;1(g) hereof.

<UL>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;CEG
shall deliver or cause to be delivered to Trustee a schedule (the "</FONT><FONT SIZE=2><B>Payment Schedule</B></FONT><FONT SIZE=2>") that indicates the amounts
payable in respect of each Plan participant (or his or her beneficiaries), that provides a formula or other instructions acceptable to Trustee for determining the amounts so payable, the form in which
such amount is to be paid (as provided for or available under the Plan), and the time of commencement for payment of such amounts. Except as otherwise provided herein, Trustee shall make payments to
the Plan participants and their beneficiaries in accordance with such Payment Schedule. If so instructed by CEG, the Trustee shall withhold federal and state taxes from each payment under this
agreement at the rate(s) designated by CEG and shall report and pay such amounts to the appropriate federal and state taxing authorities. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;The
entitlement of a Plan participant or his or her beneficiaries to benefits under the Plan shall be determined by CEG or such party as it shall designate under the
Plan and any claim for such benefits shall be considered and reviewed under
the procedures set out in the Plan. Trustee shall have no right or duty to inquire into CEG's decisions with respect to entitlement to benefits. </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;CEG
may make payment of benefits directly to Plan participants or their beneficiaries as they become due under the terms of the Plan. CEG shall notify Trustee in writing
of its decision to make payment of benefits directly prior to the time amounts are payable to participants or their beneficiaries. CEG shall provide to the Trustee documentation substantiating that
such payments were made under the terms of the Plan. If such documentation is not provided, Trustee shall make such payments in accordance with the Payment Schedule directly to Plan participants and
their beneficiaries. In addition, if the Trust Assets are not sufficient to make such payments of benefits in accordance with the terms of the Plan, CEG shall make the balance of each such payment as
it falls due. Trustee shall notify CEG where Trust Assets are not sufficient to make benefit payments, however, Trustee shall have no duty to require any contributions to be made, or to determine that
any of the contributions received comply with the conditions and limitations of the Plan. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;In
the event there is a final judicial determination or a final determination by the Internal Revenue Service that the Plan participants or their beneficiaries are
subject to any tax with respect to any amounts held under the terms of the Trust, then Trustee solely at the direction of CEG shall make payments from the Trust to such Plan participants or their
beneficiaries in such amounts as set forth in such final determination for the purpose of paying all applicable taxes and interest and any penalties thereon which such Plan participants or their
beneficiaries incur arising out of such determination. CEG's decision as to whether a final determination has occurred shall be binding and conclusive on all Plan participants and their beneficiaries. </FONT></P>

receipt of notification issued in accordance with Section&nbsp;3(b)(1) hereof, Trustee shall cease payment of benefits to Plan participants and their

(2)&nbsp;CEG is subject to a pending proceeding as a debtor under the United States Bankruptcy Code. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;At

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)&nbsp;&nbsp;&nbsp;The
Board of Directors of CEG and the Chief Executive Officer of CEG shall have the duty to inform Trustee in writing of CEG's Insolvency. When so informed or when the
Trustee is in receipt of a copy of a bankruptcy petition relating to CEG or a court order determining CEG to be Insolvent, Trustee shall discontinue payment of benefits to Plan participants or their

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

at any time Trustee has received written notification in accordance with Section&nbsp;3(b)(1), Trustee shall discontinue payments to Plan participants or their
