                                WARRANT AGREEMENT

     WARRANT AGREEMENT, dated as of [ ], among Constellation Energy Group, Inc.
(the "Company") and The Bank of New York, as warrant agent (the "Warrant
Agent").

     WHEREAS, on [ ] the Company filed with the Securities and Exchange
Commission a "shelf" registration statement on Form S-3. Under this registration
statement the Company is authorized, inter alia, to issue, from time to time,
warrants to purchase senior debt securities, convertible debt securities,
preferred stock and common stock or any combination of these securities. On [ ],
the Company resolved to issue warrants to purchase [indicate type of securities]
(the "Warrants"). The term "[ ]" as used in this Agreement refers to the [ ]
[indicate type of securities] that the Company will issue and deliver upon
exercise of the Warrants in accordance with the terms and conditions set forth
in the warrant certificates evidencing the Warrants (the "Warrant
Certificates"), such Warrant Certificates to be substantially in the form of
Exhibit A hereto; and

     WHEREAS, the Company desires the Warrant Agent to act on behalf of the
Company, and the Warrant Agent is so willing to act, in connection with the
issuance, exchange, transfer, exercise and replacement of the Warrant
Certificates, and in this Agreement wishes to set forth, among other things, the
form and provisions of the Warrant Certificates (including the Global Warrant
Certificates) and the terms and conditions on which they may be issued,
exchanged, transferred, exercised and replaced.

     NOW, THEREFORE, in consideration of these premises and other good and
valuable consideration, the parties agree to their following respective
obligations and rights:

     1.   Issuance of Warrants and Execution and Delivery of Warrant
Certificates.

     (a) All Warrant Certificates shall be in registered form, shall
contain such appropriate insertions, omissions, substitutions and other
variations as are required or permitted by this Agreement and may have such
letters, numbers or other marks of identification or designation and such
legends or endorsements placed thereon as may, consistently herewith, be
determined by a duly authorized representative of the Company (each, an
"Authorized Person"), as evidenced conclusively by the execution of such Warrant
Certificates and as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any law or with any rule or regulation.

     (b)  The Warrant Agent shall, upon receipt of the Warrant Certificates duly
executed on behalf of the Company, countersign one or more global warrant
certificates (the "Global Warrant Certificates") evidencing the Warrants and
shall, subject to

<PAGE>

paragraph (a) above, deliver such Global Warrant Certificates to or upon the
written order of the Company. Subsequent to such original issuance of the
Warrant Certificates, the Warrant Agent shall countersign Warrant Certificates
only if such Warrant Certificates are issued in exchange or substitution for one
or more previously countersigned Warrant Certificates, as the case may be, or,
in connection with their transfer, as hereinafter provided or as provided in
Section 6(a) or Section 18, but subject to the provisions of Section 7. A Global
Warrant Certificate shall be, and shall remain, subject to the provisions of
this Agreement until such time as all of the Warrants evidenced thereby shall
have been duly exercised or shall have expired or been canceled in accordance
with the terms thereof.

     No Warrant Certificate shall be valid for any purpose, and no Warrant
evidenced thereby shall be exercisable, until such Warrant Certificate has been
countersigned by the manual signature of the Warrant Agent. Such signature by
the Warrant Agent upon any Warrant Certificate executed by the Company shall be
conclusive evidence that such Warrant Certificate so countersigned has been duly
issued hereunder.

     (c)  Each Warrant Certificate shall be signed on behalf of the Company by
an Authorized Person. Such signature may be the manual or facsimile signature of
such persons and may be imprinted or otherwise reproduced on the Warrant
Certificates.

     In case any Authorized Person who shall have signed any of the Warrant
Certificates either manually or by facsimile signature shall cease to be an
Authorized Person, before the Warrant Certificates shall have been countersigned
and delivered by the Warrant Agent, such Warrant Certificates may be
countersigned and delivered notwithstanding that a person who signed such
Warrant Certificate ceased to be such an Authorized Person, and any Warrant
Certificate may be signed on behalf of the Company by such persons as, at the
actual date of the execution of such Warrant Certificate, shall be Authorized
Persons, although at the date of the execution of this Agreement any such person
was not such an Authorized Person.

     The terms "holder", "Warrant holder" or "holder of a Warrant Certificate"
as used herein shall mean any person in whose name at the time any Warrant
Certificate shall be registered upon the books to be maintained by the Warrant
Agent for that purpose.

     2.   Appointment of the Warrant Agent. The Company hereby appoints The Bank
of New York as Warrant Agent of the Company in respect of the Warrants and
Warrant Certificates, upon the terms and subject to the conditions set forth
herein and in the Warrant Certificates, and The Bank of New York hereby accepts
such appointment. The Warrant Agent shall have the powers and authority granted
to and conferred upon it herein and in the Warrant Certificates and such further
powers and authority, acceptable to it, to act on behalf of the Company as the
Company may hereafter grant to or confer upon it. All the terms and provisions
with respect to such powers and authority contained in the Warrant Certificates
are subject to and governed by the terms and provisions hereof. The Company
agrees, for the benefit of the holders from time to time of the

                                       -2-

<PAGE>

Warrant Certificates, that there shall at all times be a Warrant Agent hereunder
until the Warrants expire.

     3.   Exercise of Warrants. (a) Each Warrant entitles the registered owner
to exercise an option to purchase, at an exercise price of $[ ], U.S. $[ ] of
[  ] [indicate type of securities].

     (b)  The Warrants evidenced by a Warrant Certificate may be exercised in
whole or in part not earlier than [9:00 A.M., New York City time,] on [ ] and
[not later than 5:00 P.M., New York City time,] on [ ]. If a Warrant is not
exercised at or before [5:00 P.M., New York City time,] on [ ], it shall become
void, and all rights of the holder under Warrants and under this Agreement shall
cease. [No fewer than one Warrant may be exercised per Warrant Exercise Notice
(as defined below) and no fractional Warrants may be exercised.]

     (c)  During the period specified in Section 3(b), a Warrant, if the Warrant
Certificate evidencing the same shall have been countersigned by the Warrant
Agent, may be exercised by the holder thereof by (i) providing written notice of
such election ("Warrant Exercise Notice") to exercise the Warrant to the Warrant
Agent at [ ], "Attention: Constellation Energy Group, Inc. Warrant Exercise", or
to such other address as shall be notified in accordance with the immediately
following paragraph, by hand or by facsimile, no later than [noon, New York City
time,] on [ ], which Warrant Exercise Notice shall be in the form of an election
to purchase [ ] [indicate type of securities] substantially in the form set
forth in Exhibit B hereto, properly completed and executed by the holder;
provided that such written notice may only be submitted by or through persons
that are direct participants in The Depository Trust Company ("DTC"); (ii)
delivering, no later than [noon, New York City time,] on the Warrant Exercise
Date, such Warrants to the Warrant Agent by book-entry transfer through the
facilities of DTC or by delivering, no later than [noon, New York City time,] on
[ ], the Warrant Certificates evidencing such Warrants to the Warrant Agent if
Warrant Certificates in definitive form have been issued and delivered pursuant
to Section 7; and (iii) for each Warrant exercised, paying in full, in lawful
money of the United States of America, by bank wire transfer in immediately
available funds [add electronic payment details] no later than [11:00 A.M., New
York City time] on [ ] (the "Settlement Date"), the exercise price of U.S. $[ ].
Any exercise of a Warrant pursuant to the terms of this paragraph (c) shall be
irrevocable and shall constitute a binding agreement between the Warrant holder
and the Company, enforceable in accordance with its terms.

     (d)  Not less than 20 days before the start of the period specified in
Section 3(b), the Warrant Agent shall notify DTC of (x) the Warrant Agent's
account at DTC to which the Warrants must be delivered on the Warrant Exercise
Date and (y) the address, phone number and facsimile number where holders of the
Warrants can contact the Warrant Agent to which Warrant Exercise Notices are to
be submitted.

                                       -3-

<PAGE>

     (e)  Approximately two weeks before the start of the period specified in
Section 3(b), the Warrant Agent shall notify holders (through the clearing
system) of (1) the Warrant Agent's account at DTC to which holders must deliver
Warrants on the Warrant Exercise Date, (2) the Warrant exercise procedures of
DTC and (3) the address, telephone number and facsimile number where holders can
contact the Warrant Agent and to which holders must submit Warrant Exercise
Notices if they decide to exercise their Warrants. At such time, the Warrant
Agent shall also provide the holders with a Warrant Exercise Notice and the
pertinent instructions as to how to exercise their Warrants.

     (f)  [Further, at any time until the start of the period specified in
Section 3(b), the Warrant Agent shall provide [ ] (the "Dealer Manager"), which
has been appointed by the Company as dealer manager to solicit holders of
Warrants to exercise the Warrants, such information regarding the registered
owners of the Warrants as the Dealer Manager may reasonably request and is
reasonably available to the Warrant Agent, including a list of all registered
owners of the Warrants known to the Warrant Agent.]

     (g)  The Warrant Agent shall:

               (i)   examine all Warrant Exercise Notices and all other
          documents delivered to it by or on behalf of holders as contemplated
          by the Warrant Certificates to ascertain whether, on their face, such
          Warrant Exercise Notices and any such other documents have been
          executed and completed in accordance with their terms and the terms of
          the Warrant Certificates;

               (ii)  determine whether the exercising Warrant holder has
          delivered the related Warrants to the Warrant Agent's account at DTC.
          In each case where a Warrant Exercise Notice or other document appears
          on its face to have been improperly completed or executed or some
          other irregularity in connection with the exercise of the Warrants
          exists, the Warrant Agent will endeavor to inform the appropriate
          parties (including the person submitting such instrument) of the need
          for fulfillment of all requirements, specifying those requirements
          which appear to be unfulfilled. Except to the extent provided in the
          immediately preceding sentence, the Warrant Agent shall be under no
          duty to give notice to any person of any irregularities in Warrant
          Exercise Notices, delivery of Warrants or any other document completed
          or executed in connection therewith nor shall it incur any liability
          for failure to give such notice;

               (iii) inform the Company of and cooperate with and assist the
          Company in resolving any reconciliation problems between Warrant
          Exercise Notices received and delivery of Warrants to the Warrant
          Agent's account;

                                       -4-

<PAGE>

               (iv)  advise the Company (i) no later than [noon, New York City
          time, on the first New York business day following the expiration of
          the period specified in Section 3(b),] of receipt of any Warrant
          Exercise Notices and the number of Warrants exercised in accordance
          with the terms and conditions of this Agreement, (ii) no later than
          [noon, New York City time, on the second New York business day, as
          applicable, following the expiration of the period specified in
          Section 3(b),] of the instructions with respect to delivery of the [ ]
          [indicate type of securities] deliverable upon such exercise, subject
          to timely receipt from DTC of the necessary information, and (iii) of
          such other information as the Company shall reasonably require;

               (v)   notify, by such time as necessary to ensure a prompt
          closing, DTC, with a copy to the Company, each account at DTC to be
          credited with [ ] [indicate type of securities] and the amount thereof
          to be credited to each such account; and

               (vi)  subject to [ ] [indicate type of securities] being made
          available to the Warrant Agent by or on behalf of the Company for
          delivery to accounts within DTC, liaise with DTC and endeavor to
          effect such delivery to the relevant accounts at DTC in accordance
          with its requirements.

     (h)  All questions as to the validity, form and sufficiency (including time
of receipt) of a Warrant exercise will be determined by the Company in its sole
discretion, which determination shall be final and binding. The Company reserves
the absolute right to reject any and all Warrant Exercise Notices not in proper
form or for which any corresponding agreement by the Company to exchange would,
in the opinion of the Company, be unlawful. Moreover, the Company reserves the
absolute right to waive any of the conditions to the exercise of Warrants or
defects in Warrant Exercise Notices with regard to any particular exercise of
Warrants. None of the Company and the Warrant Agent shall be under any duty to
give notice to the holders of the Warrants of any irregularities in any exercise
of Warrants, nor shall any of them incur any liability for the failure to give
such notice.

     (i)  As soon as practicable after the exercise of any Warrant, but in no
event later than [9:00 A.M., New York City time,] on the Settlement Date, the
Company shall issue, or otherwise deliver, in authorized denominations to or
upon the order of the holder of the Warrant Certificates evidencing such
Warrants, by same-day credit to such holder's account at DTC or to the account
of a participant in DTC, in each case designated by such holder, or by the
direct participant in DTC, through which such holder is acting, in its Warrant
Exercise Notice, the [ ][indicate type of securities] to which such holder is
entitled, in fully registered form, registered in such name or names as may be
directed by such holder or such participant.

                                       -5-

<PAGE>

     4.   Rights of Holders. (a) No Warrant Certificate or Warrants evidenced
thereby shall entitle the holder thereof to any of the rights of a holder of the
[  ] [indicate type of securities].

     (b)  Notwithstanding any of the provisions of this Agreement, any holder of
Warrants may, without the consent of the Warrant Agent, the holder of any [ ]
[indicate type of securities] or the holder of any other Warrants, on its own
behalf and on behalf of any beneficial owner for whom it is acting, enforce, and
may institute and maintain any suit, action or proceeding against the Company
suitable to enforce, or may take any other action in respect of, its right to
exercise the Warrants evidenced by its Warrant Certificate in the manner
provided in such Warrant Certificate and herein.

     5.   Registration. The Warrant Agent shall keep, at its corporate trust
office, books in which, subject to such reasonable regulations as it may
prescribe, it shall register the Warrant Certificates and exchanges and
transfers of outstanding Warrant Certificates upon surrender of the Warrant
Certificates properly endorsed or accompanied by appropriate instruments of
registration of transfer and written instructions for transfer, all in form
satisfactory to the Company and the Warrant Agent. No service charge shall be
made for any exchange or registration of transfer of the Warrant Certificates,
but the Company may require payment of a sum sufficient to cover any stamp or
other tax or other governmental charge that may be imposed in connection with
any such exchange or registration of transfer.

     6.   Exchange, Transfer, Replacement and Cancellation of Warrant
Certificates.

     (a) Subject to Section 7, upon surrender at the corporate trust
office of the Warrant Agent by hand, mail or book-entry delivery, the Warrant
Certificates evidencing Warrants may be exchanged for Warrant Certificates of
the same tenor and dollar amount evidencing such Warrants or the transfer
thereof may be registered in whole or in part provided that such other Warrant
Certificates evidence the same aggregate number of Warrants as the Warrant
Certificates so surrendered. Whenever a Warrant Certificate is so surrendered
for exchange or registration of transfer, an authorized officer of the Warrant
Agent shall manually countersign and deliver to the person or persons entitled
thereto a Warrant Certificate duly authorized and executed by the Company, as so
requested. The Warrant Agent shall not be required to effect any exchange or
registration of transfer which will result in the issuance of a Warrant
Certificate evidencing a fraction of a Warrant. The Warrant Certificate issued
upon any exchange or registration of transfer of a Warrant Certificate shall be
the legal, valid and binding obligations of the Company, evidencing the same
obligations and entitled to the same benefits under this Agreement, as the
Warrant Certificates surrendered for such exchange or registration of transfer.

     (b)  Any Warrant Certificate surrendered for exchange, registration of
transfer or exercise of the Warrants evidenced thereby shall if surrendered to
the Company, be delivered to the Warrant Agent and all Warrant Certificates
surrendered or so delivered to the Warrant Agent shall be promptly canceled by
the Warrant Agent and shall not be

                                       -6-

<PAGE>

reissued and, except as expressly permitted by this Agreement, no Warrant
Certificate shall be issued hereunder in exchange or in lieu thereof. The
Warrant Agent shall deliver to the Company from time to time or otherwise
dispose of the canceled Warrant Certificates in its customary manner.

     (c)  Upon receipt by the Warrant Agent of evidence reasonably satisfactory
to it of the ownership of and the loss, theft, destruction or mutilation of any
Warrant Certificate and of indemnity reasonably satisfactory to it and, in the
case of mutilation, upon surrender thereof to the Warrant Agent for
cancellation, then, in the absence of notice to the Company or a responsible
corporate trust officer of the Warrant Agent that such Warrant Certificate has
been acquired by a bona fide purchaser, the Company shall execute, and an
authorized officer of the Warrant Agent shall manually countersign and deliver,
in exchange for or in lieu of the lost, stolen, destroyed or mutilated Warrant
Certificate, a new Warrant Certificate of the same tenor and evidencing like
Warrants. Every substitute Warrant Certificate executed and delivered pursuant
to this Section in lieu of any lost, stolen or destroyed Warrant Certificate
shall represent an additional contractual obligation of the Company, whether or
not the lost, stolen or destroyed Warrant Certificate shall be at any time
enforceable by anyone, and shall be entitled to the benefits of this Agreement
equally and proportionately with any and all other Warrant Certificates duly
executed and delivered hereunder. The provisions of this Section are exclusive
and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement of mutilated, lost, stolen or destroyed Warrant
Certificates.

     (d)  Upon the issuance of any new Warrant Certificate under this Section,
the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Warrant Agent) in connection
therewith.

     (e)  The holder of a Warrant Certificate, by accepting the same, consents
and agrees with the Company, the Warrant Agent and with every subsequent holder
of such Warrant Certificate that until the transfer of the Warrant Certificate
is registered on the books of the Warrant Agent, the Company and the Warrant
Agent may treat such registered holder as the absolute owner thereof for any
purpose and as the person entitled to exercise the rights represented by the
Warrant evidenced thereby, any notice to the contrary notwithstanding.

     7.   Global Securities. The Warrants shall be issued initially in the form
of one or more Global Warrant Certificates that will be deposited with, or on
behalf of, DTC. Global Warrant Certificates may be issued only in fully
registered form and in either temporary or definitive form. Unless and until it
is exchanged in whole or in part for Warrant Certificates in definitive form, a
Global Warrant Certificate may not be transferred except as a whole by DTC to a
nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC
or any nominee of DTC to a successor depositary or any nominee of such
successor.

                                       -7-

<PAGE>

     So long as DTC, or its nominee, is the registered owner of a Global Warrant
Certificate, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the Warrants represented by such Global Warrant
Certificate for all purposes under this Agreement. Except as specified below
with respect to Warrants only, owners of beneficial interests in a Global
Warrant Certificate will not be entitled to have any Warrants registered in
their names, and will not receive or be entitled to receive physical delivery of
any such Warrants in definitive form and will not be considered the owners or
holders thereof under the Warrants or this Agreement. Neither the Company nor
the Warrant Agent, in its capacity as registrar for such Warrants, will have any
responsibility or liability for any aspect of the records relating to beneficial
interests in a Global Warrant Certificate or for maintaining, supervising or
reviewing any records relating to such beneficial interests.

     If at any time DTC notifies the Company that it is unwilling or unable to
continue as depositary for the Warrants, or if the Company notifies DTC that it
will no longer continue to use DTC as depositary for the Warrants, or if at any
time DTC ceases to be a clearing agency registered under the United States
Securities Exchange Act of 1934, as amended, or otherwise ceases to be eligible
to be a depositary, the Company shall appoint a successor depositary with
respect to the Warrants (and all references to DTC herein shall be deemed to
include such successor depositary). If a successor depositary for the Warrants
is not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such ineligibility, the Company will execute, and the
Warrant Agent upon receipt of such executed definitive Warrant Certificates will
authenticate and deliver, Warrant Certificates in definitive registered form
evidencing an aggregate number of Warrants equal to the aggregate number of
Warrants evidenced by the Global Warrant Certificate.

     The Company may at any time and in its sole discretion determine not to
have any of the Warrants evidenced by Global Warrant Certificates. In such
event, the Company will execute, and the Warrant Agent, upon receipt of such
executed definitive Warrant Certificates, will authenticate and deliver Warrant
Certificates in definitive registered form, in an aggregate amount equal to the
aggregate number of Warrants evidenced by such Global Warrant Certificates.

     Upon the exchange of the Global Warrant Certificates for Warrant
Certificates in definitive registered form, the Global Warrant Certificates
shall be canceled by the Warrant Agent.

     Warrant Certificates in definitive registered form issued in exchange for
the Global Warrant Certificates pursuant to this section shall be registered in
such names as DTC, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Warrant Agent or the Company. The
Warrant Agent shall deliver such Warrant Certificates in definitive registered
form to or as directed by the persons in whose names such definitive registered
Warrant Certificates are so registered.

                                       -8-

<PAGE>

     All Warrant Certificates in definitive registered form, issued upon the
exchange of the Global Warrant Certificates, shall be valid obligations of the
Company, evidencing the rights, and entitled to the same benefits under this
Agreement, as the Global Warrant Certificates surrendered upon such exchange.

     8.   Rights of Warrant Agent. The Company shall have the following
obligations to the Warrant Agent and the Warrant Agent shall have the following
rights:

     (a)  In acting under this Agreement and in connection with the Warrant
Certificates, the Warrant Agent is acting solely as agent of the Company and
does not assume any obligation towards or relationship of agency or trust for or
with the owners or holders of Warrants.

     (b)  The Warrant Agent shall be entitled to compensation, as agreed upon
with the Company, for all services rendered by it and expenses incurred in
connection therewith, and the Company agrees promptly to pay such compensation
and to reimburse the Warrant Agent for any agreed upon expenses incurred by the
Warrant Agent in connection with the services rendered by it (as documented in
an invoice setting forth such expenses).

     (c)  The Warrant Agent shall be entitled to consult with counsel and the
opinion, written or otherwise, of such counsel shall be full and complete
authorization and protection in respect of any action taken, omitted to be taken
or suffered by it hereunder in good faith and in accordance with the opinion of
such counsel.

     (d)  The Warrant Agent shall be protected and shall incur no liability for
or in respect of any action taken or omitted to be taken or anything suffered by
it in reliance upon the Warrants, any Warrant Certificate, the [ ] [indicate
type of securities] or any notice, direction, consent, certificate, affidavit,
statement or other paper or document (whether in its original or facsimile form)
reasonably believed by it to be genuine and to have been passed or signed by the
proper parties.

     (e)  The Warrant Agent or any of its officers, directors and employees may
become the beneficial owner of, or acquire an interest in, Warrants or [ ]
[indicate type of securities] with the same rights that it would have if it were
not the Warrant Agent hereunder, and to the extent permitted by applicable law,
may engage in or be interested in any financial or other transaction with the
Company, and may act on behalf of, or as depositary, trustee or agent for, any
committee or body of beneficial owners of the Warrants, the [ ] [indicate type
of securities], or other obligations of the Company, as freely as if it were not
the Warrant Agent hereunder.

     (f)  The recitals contained herein and in the Warrant Certificates (except
in the Warrant Agent's certificate of authentication on the Warrant
Certificates) shall be taken as the statements of the Company and the Warrant
Agent assumes no responsibility for the correctness of the same. The Warrant
Agent makes no representation as to the validity

                                       -9-

<PAGE>

or sufficiency of this Agreement or the Warrant Certificates except for the due
authorization of the Warrant Agent to execute this Agreement.

     (g)  The Warrant Agent shall be obligated to perform such duties and only
such duties as are herein and in the Warrant Certificates specifically set forth
and no implied duties or obligations shall be read into this Agreement or the
Warrant Certificates against the Warrant Agent. The Warrant Agent shall not be
under any obligation to take any action hereunder which may tend to involve it
in any reimbursable expense or liability, the payment of which within a
reasonable time is not in its reasonable opinion, assured to it.

     (h)  Unless otherwise specifically provided herein or in the Warrant
Certificates, any order, certificate, notice, request, direction or other
communication from the Company made or given by the Company under any provision
of this Agreement shall be sufficient if signed by an Authorized Person of the
Company.

     (i)  If the Warrant Agent shall receive any notice or demand (other than
notice of or demand for exercise of Warrants) addressed to the Company by the
holder of the Warrant Certificates pursuant to the provisions of the Warrant
Certificates, the Warrant Agent shall promptly forward such notice or demand to
the Company.

     (j)  The Warrant Agent may at any time resign as Warrant Agent, by giving
written notice to the Company of such intention on its part, mailed to the
Company at its address set forth in Section 12, specifying the date on which its
desired resignation shall become effective; provided, however, that such date
shall never be less than 90 days after the date of receipt of such notice by the
Company unless the Company agrees to accept shorter notice. The Warrant Agent
may be removed at any time by the filing with it of an instrument in writing
signed by an Authorized Person of the Company and specifying such removal and
the date when it is intended to become effective. Such resignation or removal
shall take effect upon the date of the appointment by the Company, as
hereinafter provided, of a successor Warrant Agent (which shall be a bank or
trust company authorized under the laws of the jurisdiction of its incorporation
to exercise corporate trust powers) and the acceptance of such appointment by
the successor Warrant Agent. If a successor Warrant Agent is not appointed by
the Company within 90 days after the resignation of the Warrant Agent, the
Warrant Agent shall be entitled to petition at the expense of the Company a
court of competent jurisdiction for appointment of a successor Warrant Agent.
Upon its resignation or removal, the Warrant Agent shall be entitled to the
payment by the Company of its compensation for the services rendered hereunder
and to the reimbursement of all reasonable and duly documented out-of-pocket
expenses (including reasonable and duly documented counsel fees) incurred in
connection with the services rendered hereunder (as described in Section 8(b)).
The indemnity described in Section 9 shall survive any resignation or removal of
the Warrant Agent or the termination of this Agreement.

                                      -10-

<PAGE>

     (k)  In case at any time the Warrant Agent shall resign, or shall be
removed, or shall become incapable of acting, or shall be adjudged a bankrupt or
insolvent, or shall file a voluntary petition in bankruptcy or make an
assignment for the benefit of its creditors or consent to the appointment of a
receiver of all or any substantial part of its property or affairs or shall
generally not pay its debts as such debts become due, or shall admit in writing
its inability to pay or meet its debts generally as they become due, or if an
order of any court shall be entered approving any petition filed by or against
the Warrant Agent under the provisions of bankruptcy laws or any similar
legislation, or if a receiver, trustee or other similar official of it or of all
or any substantial part of its property shall be appointed, or if any public
officer shall take charge or control of it or of its property or affairs, for
the purpose of rehabilitation, conservation, protection, relief, winding up or
liquidation, a successor Warrant Agent shall be appointed by the Company by an
instrument in writing, filed with the successor Warrant Agent. Upon the
appointment as aforesaid of a successor Warrant Agent and acceptance by it of
such appointment, the Warrant Agent so superseded shall, if not previously
