         Section 3. Designation of Trust and Certificates. The Trust created
hereby shall be known as the "Corporate Backed Trust Certificates,
Georgia-Pacific Debenture-Backed Series 2001-29 Trust." The Certificates
evidencing certain undivided ownership interests therein shall be known as
"Corporate Backed Trust Certificates, Georgia-Pacific Debenture-Backed Series
2001-29." The Certificates shall consist of the Class A-1 Certificates and the
Class A-2 Certificates (together, the "Certificates").

         (a) The Certificates shall be held through the Depository in book-entry
form and shall be substantially in the forms attached hereto as Exhibit A-1 and
A-2. The Class A-1 Certificates shall be issued in denominations of $25. The
Class A-2 Certificates shall be issued in minimum notional denominations of
$1,000 and integral multiples of $1 in excess thereof. Except as provided in the
Standard Terms and in paragraph (d) of this Section, the Trust shall not issue
additional Certificates or incur any indebtedness.

         (b) The Class A-1 Certificates have an initial aggregate certificate
principal amount (the "Certificate Principal Amount") of $33,900,000. The Class
A-2 Certificates are interest-only Certificates, and have a notional amount
equal to the aggregate principal amount of the Underlying Securities.

         (c) The holders of the Class A-1 Certificates will be entitled to
receive on each Distribution Date the interest, if any, received on the
Underlying Securities, to the extent necessary to pay interest at a rate of
8.50% per annum on the outstanding Certificate Principal Amount of the Class A-1
Certificates. The holders of the Class A-2 Certificates will be entitled to
receive on each Distribution Date the interest, if any, received on the
Underlying Securities, to the extent necessary to pay interest at a rate of
0.125% per annum on the outstanding notional amount of the Class A-2
Certificates. On October 30, 2001, the Trustee will pay to the Depositor the
amount of interest accrued and paid on the Underlying Securities from April 30,
2001, to but not including the Closing Date. If Available Funds are insufficient
to pay such amount, the Trustee will pay the Depositor its pro rata share, based
on the ratio the amount owed to the Depositor bears to all the amounts owed on
the Certificates in respect of accrued interest, of any proceeds from the
recovery on the Underlying Securities.

                                       7
<PAGE>

         (d) The Depositor may sell to the Trustee additional Underlying
Securities on any date hereafter upon at least 3 Business Days (or such lesser
period as may be agreed by the parties hereto) notice to the Trustee and upon
(i) satisfaction of the Rating Agency Condition and (ii) delivery of an Opinion
of Counsel to the effect that the sale of such additional Underlying Securities
will not materially increase the likelihood that the Trust would fail to qualify
as a grantor trust under the Code. Upon such sale to the Trustee, the Trustee
shall deposit such additional Underlying Securities in the Certificate Account,
and shall authenticate and deliver to the Depositor, on its order, Class A-1
Certificates and Class A-2 Certificates in the same proportion as the original
Class A-1 Certificates and Class A-2 Certificates bear to the original
Underlying Securities. Any such additional Class A-1 Certificates and Class A-2
Certificates authenticated and delivered shall have the same terms and rank pari
passu with the original Class A-1 Certificates and Class A-2 Certificates,
respectively, issued in accordance with this Series Supplement.

         Section 4. Trust Certificates. The Trustee hereby acknowledges receipt,
on or prior to the Closing Date, of:

         (a) the Underlying Securities set forth on the Underlying Securities
Schedule; and

         (b) all documents required to be delivered to the Trustee pursuant to
Section 2.01 of the Standard Terms.

         Section 5. Distributions. (a) Except as otherwise provided in Section
3(c), on each applicable Distribution Date, the Trustee shall apply Available
Funds in the Certificate Account as follows, in the following order of priority:

                  (i)      the Trustee will pay the interest portion of

                           (2) second, to the holders of the Class A-1

                           (3) third, any remainder to the Depositor.

                  (ii)     the Trustee will pay the principal portion of
                           Available Funds:

                           (1) first, to the Trustee, as reimbursement for any
remaining Extraordinary Trust Expenses incurred by the Trustee with respect to
the Underlying Securities in accordance with Section 6(b) below and approved by
100% of the Certificateholders; and

<PAGE>

         (b) Notwithstanding any other provision hereof, in the event that the
Underlying Securities are redeemed, prepaid or liquidated in whole or in part
for any reason other than (i) due to the occurrence of an Event of Default, (ii)
the failure of the Underlying Securities Issuer to file periodic reports as
required by the Exchange Act, (iii) a call of the Underlying Securities by the
Underlying Securities Issuer, or (iv) at their maturity, the Trustee shall apply
Available Funds in the manner described in Section 5(h) in the following order
of priority:

                  (i) first, to the Trustee, as reimbursement for any
Extraordinary Trust Expenses incurred by the Trustee with respect to the
Underlying Securities in accordance with Section 6(b) below and approved by 100%
of the Certificateholders;

                  (ii) second, to the holders of the Class A-1 Certificates, an
amount equal to the outstanding principal amount thereof plus accrued and unpaid
interest thereon;

                  (iii) third, to the holders of the Class A-2 Certificates, the
present value of all amounts that would otherwise have been payable on the Class
A-2 Certificates for the period from the date of such redemption or prepayment
to the Final Scheduled Distribution Date using a discount rate of 8.50% per
annum, assuming no delinquencies, deferrals, redemptions or prepayments on the
Underlying Securities; and

                  (iv) fourth, any remainder to the holders of the Class A-1
Certificates and Class A-2 Certificates pro rata in proportion to the ratio of
the Class A-1 Allocation to the Class A-2 Allocation.

         (c) Notwithstanding any other provision hereof, in the event that the
Underlying Securities are redeemed, prepaid or liquidated in whole or in part
due to the occurrence of an Event of Default or the failure by the Underlying
Securities Issuer to file the periodic reports required under the Exchange Act,
the Trustee shall apply Available Funds to the holders of the Class A-1
Certificates and the holders of the Class A-2 Certificates in accordance with
the ratio of the Class A-1 Allocation to the Class A-2 Allocation.

         (d) Unless otherwise instructed by holders of Certificates representing
a majority of the Voting Rights, thirty (30) days after giving notice pursuant
to Section 8 hereof, the Trustee shall sell the Underlying Securities pursuant
to Section 13 hereof and deposit the Liquidation Proceeds, if any, into the
Certificate Account for distribution not later than two (2) Business Days after
the receipt of immediately available funds in accordance with Section 5 (c)
hereof.

         (e) Notwithstanding any other provision hereof, in the event that the
Underlying Securities are called in whole or in part by the Underlying
Securities Issuer, the holders of the Class A-1 Certificates will share all
amounts received in respect of such call including the redemption premium, if
any, paid by the Underlying Securities Issuer pro rata in the proportion that
the outstanding principal amount of their respective Class A-1 Certificates

                                       9
<PAGE>

bears to the outstanding aggregate principal amount of the Class A-1
Certificates.

         (f) In the event that the Trustee receives non-cash property in respect
of the Underlying Securities as a result of a payment default on the Underlying
Securities (including from the sale thereof), the Trustee will promptly give
notice to the Depository, or for any Certificates which are not then held by DTC
or any other depository, directly to the registered holders of the Certificates
then outstanding and unpaid. Such notice shall state that, not later than 30
days after the receipt of such property, the Trustee will allocate and
distribute such property to the holders of Class A-1 Certificates and Class A-2
Certificates then outstanding and unpaid in accordance with Section 5(c) hereof
(after deducting the costs incurred in connection therewith). Property other
than cash will be liquidated by the Trustee, and the proceeds thereof
distributed in cash, only to the extent necessary to avoid distribution of
fractional securities to Certificateholders. In-kind distribution of Underlying
Securities to Certificateholders will be deemed to reduce the principal amount
and notional principal amount of the Class A-1 Certificates and Class A-2
Certificates, respectively, on a dollar-for-dollar basis.

         (g) Subject to Section 9(f) hereof, to the extent Available Funds are
insufficient to make any required distributions due to any class of Certificates
on any Distribution Date, any shortfall will be carried over and will be
distributed on the next Distribution Date (or date referred to in Section 5(h)
hereof) on which sufficient funds are available to pay such shortfall.

         (h) If a payment with respect to the Underlying Securities is made to
the Trustee after the Distribution Date on which such payment was scheduled to
be distributed in respect of the Certificates, then the Trustee will distribute
any such amounts received on the next occurring Business Day (a "Special
Distribution Date") as if the funds had constituted Available Funds on the
Distribution Date immediately preceding such Special Distribution Date;
provided, however, that the Record Date for such Special Distribution Date shall
be five Business Days prior to the day on which the related payment was received
from the Underlying Securities Trustee.

         (i) Notwithstanding Section 3.12 of the Standard Terms, if the
Underlying Securities Issuer ceases to file periodic reports as required under
the Exchange Act, the Depositor shall within a reasonable time instruct the
Trustee to sell the Underlying Securities and distribute the proceeds of such
sale to the Certificateholders in accordance with the following order of
priority: first, to the Trustee, as reimbursement for any Extraordinary Trust
Expenses incurred by the Trustee in accordance with Section 6(b) below and
approved by 100% of the Certificateholders; and second, any remainder to the
holders of the Class A-1 Certificates and the Class A-2 Certificates pro rata in
proportion to the ratio of the Class A-1 Allocation to the Class A-2 Allocation;
provided, however, the Depositor shall not instruct the Trustee to distribute or
sell the Underlying Securities pursuant to this clause unless the Underlying
Securities Issuer has either (x) stated in writing that it intends permanently
to cease filing reports required under the Exchange Act or (y) failed to file
any required reports for one full calendar year.

         Section 6. Trustee's Fees. (a) As compensation for its services
hereunder, the Trustee shall be entitled to the Trustee Fee. The Trustee Fee
shall be paid by the Depositor and not from Trust Property. The Trustee shall
bear all Ordinary Expenses. Failure by the Depositor to pay such amount shall
not entitle the Trustee to any payment or reimbursement from the Trust, nor
shall such failure release the Trustee from the duties it is required to perform
under the Trust Agreement.

         (b) Extraordinary Expenses shall not be paid out of the Trust Property
unless all the Class A-1 Certificateholders and Class A-2 Certificateholders
then outstanding have directed the Trustee to incur such Extraordinary Expenses.
The Trustee may incur other Extraordinary Expenses if any lesser percentage of
the Certificateholders requesting such action pursuant hereto reimburse the
Trustee for the cost thereof from their own funds in advance. If Extraordinary
Expenses are not approved unanimously as set forth in the first sentence of this
Section 6(b), such Extraordinary Expenses shall not be an obligation of the
Trust, and the Trustee shall not file any claim against the Trust therefor
notwithstanding failure of Certificateholders to reimburse the Trustee.

         Section 7. Optional Exchange.

         (a) On any Distribution Date, any holder of Class A-1 Certificates and
Class A-2 Certificates may exchange such Certificates for a distribution of
Underlying Securities representing the same percentage of the Underlying
Securities as such Certificates represent of all outstanding Certificates.

         (b) The following conditions shall apply to any Optional Exchange.

                  (i) Any Affiliate of the Depositor must provide notice to the
Trustee (an "Exchange Request") no less than 15 days (or such shorter period
acceptable to the Trustee) but not more than 30 days prior to an Optional
Exchange Date that it requests an Optional Exchange of Certificates on such
Optional Exchange Date.

                  (ii) Class A-1 Certificates and Class A-2 Certificates
representing a like percentage of all Class A-1 Certificates and Class A-2
Certificates shall be surrendered.

                  (iii) The Trustee shall have received an opinion of counsel
stating that the Optional Exchange would not affect the characterization of the
Trust as a "grantor trust" for federal income tax purposes.

                  (iv) The Trustee shall not be obligated to determine whether
an Optional Exchange complies with the applicable provisions for exemption under
Rule 3a-7 of the Investment Company Act of 1940, as amended, or the rules or
regulations promulgated thereunder.

                  (v) Any such Optional Exchange by any Affiliate of the
Depositor, will be subject to the following restrictions: (a) certification to
the Trustee that any Certificates to be exchanged have been held for a minimum

                                       11
<PAGE>

of six months and (b) each Optional Exchange is limited in amount to a maximum
of 5% (except for Certificates acquired by the Underwriter but never distributed
to investors, in which case 25%) of the then outstanding principal amount of the
Certificates.

                  (vi) The provisions of Section 4.07 of the Standard Terms
shall not apply to an Optional Exchange pursuant to this Section. This Section 7
shall not provide the Depositor with a lien against, an interest in or a right
to specific performance with respect to the Underlying Securities.

         Section 8. Notices of Events of Default.

                  As promptly as practicable after, and in any event within 30
days after, the occurrence of any Event of Default actually known to the
Trustee, the Trustee shall give notice of such Event of Default to the
Depository, or, if any Certificates are not then held by DTC or any other
depository, directly to the registered holders of such Certificates. However,
except in the case of an Event of Default relating to the payment of principal
of or interest on any of the Underlying Securities, the Trustee will be
protected in withholding such notice if in good faith it determines that the
withholding of such notice is in the interest of the Certificateholders.

         Section 9. Miscellaneous.

         (a) The provisions of Section 4.04, Advances, of the Standard Terms
shall not apply to the Series 2001-29 Certificates.

         (b) The provisions of Section 4.07, Optional Exchange, of the Standard
Terms shall not apply to the Series 2001-29 Certificates.

         (c) The Trustee shall simultaneously forward reports to
Certificateholders pursuant to Section 4.03 of the Standard Terms and to the New
York Stock Exchange.

         (d) Except as expressly provided herein, the Certificateholders shall
not be entitled to terminate the Trust or cause the sale or other disposition of
the Underlying Securities.

         (e) The provisions of Section 3.07(d) of the Standard Terms shall not
apply to the Series 2001-29 Certificates.

         (f) If the Trustee has not received payment with respect to a
Collection Period on the Underlying Securities on or prior to the related
Distribution Date, such distribution will be made promptly upon receipt of such
payment. No additional amounts shall accrue on the Certificates or be owed to
Certificateholders as a result of such delay; provided, however, that any
additional interest owed and paid by the Underlying Securities Issuer as a
result of such delay shall be paid to the Certificateholders, proportionately to
the ratio of their respective entitlements to interest.

                                       12
<PAGE>

         (g) The outstanding principal balance of the Certificates shall not be
reduced by the amount of any Realized Losses (as defined in the Standard Terms).

         (h) The Trust may not engage in any business or activities other than
in connection with, or relating to, the holding, protecting and preserving of
the Trust Property and the issuance of the Certificates, and other than those
required or authorized by the Trust Agreement or incidental and necessary to
accomplish such activities. The Trust may not issue or sell any certificates or
other obligations other than the Certificates or otherwise incur, assume or
guarantee any indebtedness for money borrowed.

         (i) Notwithstanding anything in the Trust Agreement to the contrary,
the Trustee may be removed upon 60 days prior written notice delivered by the
holders of the Class A-1 Certificates representing the Required
Percentage-Removal.

         (j) In the event that the Internal Revenue Service challenges the
characterization of the Trust as a grantor trust, the Trustee shall then file
such forms as the Depositor may specify to establish the Trust's election
pursuant to Section 761 of the Code to exclude the Trust from the application of
Subchapter K of the Code and is hereby empowered to execute such forms on behalf
of the Certificateholders.

         (k) Notwithstanding anything in the Standard Terms to the contrary, the
Trustee, upon written direction by the Depositor, will execute the Certificates.

         (l) In relation to Section 7.01(f) of the Standard Terms, any periodic
reports filed by the Trustee pursuant to the Securities and Exchange Act of
1934, as amended, and the rules and regulations promulgated thereunder, in
accordance with the customary practices of the Depositor, need not contain any
independent reports.

         (m) Notwithstanding anything in the Trust Agreement to the contrary,
the Trustee will have no recourse to the Underlying Securities.

         (n) The Trust will not merge or consolidate with any other entity
without confirmation from each Rating Agency that such merger or consolidation
will not result in the qualification, reduction or withdrawal of its
then-current rating on the Certificates.

         (o) Notices. All directions, demands and notices hereunder or under the
Standard Terms shall be in writing and shall be delivered as set forth below
(unless written notice is otherwise provided to the Trustee).

         Section 10. Governing Law. THIS SERIES SUPPLEMENT AND THE TRANSACTIONS
DESCRIBED HEREIN SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED WITHIN
THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE CHOICE OF LAWS PROVISIONS
THEREOF.

         Section 11. Counterparts. This Series Supplement may be executed in any
number of counterparts, each of which shall be deemed to be an original, and all
such counterparts shall constitute but one and the same instrument.

         Section 12. Termination of the Trust. The Trust shall terminate upon
the earliest to occur of (i) the payment in full at maturity or sale by the
Trust after a payment default on or an acceleration or other early payment or
call of the Underlying Securities and the distribution in full of all amounts
due to the Class A-1 Certificateholders and Class A-2 Certificateholders; (ii)
the Final Scheduled Distribution Date and (iii) the expiration of 21 years from
the death of the last survivor of the descendants of Joseph P. Kennedy, the late
Ambassador of the United States to the Court of St. James, living on the date
hereof.

         Section 13. Sale of Underlying Securities; Optional Exchange.. In the
event of a sale of the Underlying Securities pursuant to Section 5(d) hereof,
the Trustee shall solicit bids for the sale of the Underlying Securities with
settlement thereof on or before the third (3rd) Business Day after such sale
from three leading dealers in the relevant market. Any of the following dealers
(or their successors) shall be deemed to qualify as leading dealers: (1) Credit
Suisse First Boston Corporation, (2) Goldman, Sachs & Co., (3) Merrill Lynch,
Pierce, Fenner & Smith Incorporated, (4) UBS Warburg LLC, (5) Salomon Smith
Barney Inc., and (6) Lehman Brothers Inc. The Trustee shall not be responsible
for the failure to obtain a bid so long as it has made reasonable efforts to
obtain bids. If a bid for the sale of the Underlying Securities has been
accepted by the Trustee but the sale has failed to settle on the proposed
settlement date, the Trustee shall request new bids from such leading dealers to
the Class A-1 Certificateholders and Class A-2 Certificateholders. In the event
of an Optional Exchange, the Trustee shall only deliver the Underlying
Securities to the purchaser of such Underlying Securities or sell the Underlying
Securities pursuant to this Section 13, as the case may be, against payment in
same day funds deposited into the Certificate Account.

         Section 14. Amendments. Notwithstanding anything in the Trust Agreement
to the contrary, in addition to the other restrictions on modification and
amendment contained therein, the Trustee shall not enter into any amendment or
modification of the Trust Agreement which would adversely affect in any material
respect the interests of the holders of any class of Certificates without the
consent of the holders of 100% of such class of Certificates; provided, however,
that no such amendment or modification will be permitted which would alter the
status of the Trust as a grantor trust for federal income tax purposes. Further,
no amendment shall be permitted which would adversely affect in any material
respect the interests of any Class of Certificateholders without confirmation by

                                       15
<PAGE>

each Rating Agency that such amendment will not result in a downgrading or
withdrawal of its rating of such Certificates.

         Section 15. Voting of Underlying Securities, Modification of Indenture.
The Trustee, as holder of the Underlying Securities, has the right to vote and
give consents and waivers in respect of the Underlying Securities as permitted
by the Depository and except as otherwise limited by the Trust Agreement. In the
event that the Trustee receives a request from the Depository, the Underlying
Securities Trustee or the Underlying Securities Issuer for its consent to any
amendment, modification or waiver of the Underlying Securities, the Underlying
Securities Indenture or any other document thereunder or relating thereto, or
receives any other solicitation for any action with respect to the Underlying
Securities, the Trustee shall mail a notice of such proposed amendment,
modification, waiver or solicitation to each Certificateholder of record as of
such date. The Trustee shall request instructions from the Certificateholders as
to whether or not to consent to or vote to accept such amendment, modification,
waiver or solicitation. The Trustee shall consent or vote, or refrain from
consenting or voting, in the same proportion (based on the relative outstanding
principal balances of the Certificates) as the Certificates of the Trust were
actually voted or not voted by the Certificateholders thereof as of a date
determined by the Trustee prior to the date on which such consent or vote is
required; provided, however, that, notwithstanding anything in the Trust
Agreement to the contrary, the Trustee shall at no time vote on or consent to
any matter (i) unless such vote or consent would not (based on an opinion of
counsel) alter the status of the Trust as a grantor trust for federal income tax
purposes or result in the imposition of tax upon the Certificateholders, (ii)
which would alter the timing or amount of any payment on the Underlying
Securities, including, without limitation, any demand to accelerate the
Underlying Securities, except in the event of a default under the Underlying
Securities or an event which with the passage of time would become an event of
default under the Underlying Securities and with the unanimous consent of all
outstanding Certificateholders, or (iii) which would result in the exchange or
substitution of any of the outstanding Underlying Securities pursuant to a plan
for the refunding or refinancing of such Underlying Securities except in the
event of a default under the Underlying Securities Indenture and only with the
consent of Certificateholders representing 100% of the Certificates. The Trustee
shall have no liability for any failure to act resulting from
Certificateholders' late return of, or failure to return, directions requested
by the Trustee from the Certificateholders.

         In the event that an offer is made by the Underlying Securities Issuer
to issue new obligations in exchange and substitution for any of the Underlying
Securities, pursuant to a plan for the refunding or refinancing of the
outstanding Underlying Securities or any other offer is made for the Underlying
Securities, the Trustee shall notify all of the Certificateholders of such offer
promptly. The Trustee must reject any such offer unless the Trustee is directed
by the affirmative vote of the holders of 100% of all of the Certificates to
accept such offer and the Trustee has received the tax opinion described above.
If pursuant to the preceding sentence, the Trustee accepts any such offer, the
Trustee shall promptly notify the Rating Agencies.

                                       16
<PAGE>

         If an event of default under the Indenture occurs and is continuing,
and if directed by a majority of the outstanding Certificateholders, the Trustee
shall vote the Underlying Securities in an outstanding principal amount equal to
the outstanding certificate principal amount of the Certificates in favor of
directing, or take such other action as may be appropriate to direct, the
Underlying Securities Trustee to declare the unpaid principal amount of the
Underlying Securities and any accrued and unpaid interest thereon to be due and
payable.

of 21 years from the death of the last survivor of the descendants of Joseph P.

     This STOCK WARRANT AGREEMENT, dated as of __________________, between CCC
Information Services Group Inc., a Delaware corporation (the "Company"), and
_______________, a ________________ organized and existing under the laws of
________________ (the "Warrant Agent").

     WHEREAS, the Company proposes to sell certificates evidencing one or more
warrants (the " Stock Warrants" or, individually, a " Stock Warrant")
representing the right to purchase [common stock, par value $0.01 per share, of
the Company (the "Common Shares")] [shares of a series of preferred stock, par
value $1.00 per share, of the Company (the "Preferred Shares")], such warrant
certificates and other warrant certificates issued pursuant to this Agreement
being herein called the "Warrant Certificates";

     WHEREAS, the Company has duly authorized the execution and delivery of this
Stock Warrant Agreement to provide for the issuance of Stock Warrants to be
exercisable at such times and for such prices, and to have such other
provisions, as shall be fixed as hereinafter provided; and

     WHEREAS, the Company desires the Warrant Agent to act on behalf of the
Company, and the Warrant Agent is willing so to act in connection with the
issuance of the Warrant Certificates and other matters as provided herein.

     NOW, THEREFORE, in consideration of the premises and of the mutual
agreements herein contained, the parties hereto agree as follows:

                                    ARTICLE I

                  ISSUANCE OF STOCK WARRANTS AND EXECUTION AND
                        DELIVERY OF WARRANT CERTIFICATES

     Section 1.1 Issuance of Stock Warrants. Stock Warrants may be issued from
time to time. Prior to the issuance of any Stock Warrants, there shall be
established by or pursuant to a resolution or resolutions duly adopted by the
Company's Board of Directors or by any committee thereof duly authorized to act
with respect thereto (a "Board Resolution"):

(a)  the title and aggregate number of such Stock Warrants;

(b)  the offering price of such Stock Warrants, if any;

(c)  the designation, number and terms (including any subordination and
     conversion provisions) of any Preferred Shares that are purchasable upon
     exercise of such Stock Warrants;]

(d)  the time or times at which, or period or periods during which, such Stock
     Warrants may be exercised and the final date on which such Stock Warrants
     may be exercised (the "Expiration Date");

(e)  the number of [Preferred/Common] Shares that may be purchased upon exercise
     of such Stock Warrants; the price, or the manner of determining the price
     (the "Warrant Price"), at which such [Preferred/Common] Shares may be
     purchased upon exercise of the Stock Warrants; and any minimum or maximum
     number of such Stock Warrants that are exercisable at any one time;

(f)  if applicable, any anti-dilution provisions of such Stock Warrants;

(g)  the terms of any right to redeem or call such Stock Warrants;

(h)  the terms of any right of the Company to accelerate the Expiration Date of
     the Stock Warrants upon the occurrence of certain events; and

(i)  any other terms of such Stock Warrants not inconsistent with the provisions
     of this Agreement.

     Section 1.2 Form and Execution of Warrant Certificates. (a) The Stock
Warrants shall be evidenced by the Warrant Certificates, which shall be in
registered form and substantially in such form or forms as shall be established
by or pursuant to a Board Resolution. Each Warrant Certificate, whenever issued,

<PAGE>

shall be dated the date it is countersigned by the Warrant Agent and may have
such letters, numbers or other marks of identification and such legends or
endorsements printed, lithographed or engraved thereon 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 made pursuant thereto or with any rule or
regulation of any securities exchange on which the Stock Warrants may be listed,
or to conform to usage, as the officer of the Company executing the same may
approve (such officer's execution thereof to be conclusive evidence of such
approval). Each Warrant Certificate shall evidence one or more Stock Warrants.

     (b) The Warrant Certificates shall be signed in the name and on behalf of
the Company by its Chairman of the Board of Directors, its President, an
Executive Vice President, any Vice President, the Treasurer or any Assistant
Treasurer and by its Secretary or any Assistant Secretary. Such signatures may
be manual or facsimile signatures of the present or any future holder of any
such office and may be imprinted or otherwise reproduced on the Warrant
Certificates, subject to the Company's By-Laws as in effect from time to time.
The seal of the Company may be in the form of a facsimile thereof and may be
impressed, affixed, imprinted or otherwise reproduced on the Warrant
Certificates.

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

     (d) In case any officer of the Company who shall have signed any Warrant
Certificate either manually or by facsimile signature shall cease to be such
officer before the Warrant Certificate so signed shall have been countersigned
and delivered by the Warrant Agent, such Warrant Certificate nevertheless may be
countersigned and delivered as though the person who signed such Warrant
Certificate had not ceased to be such officer of the Company; and any Warrant
Certificate may be signed on behalf of the Company by such person as, at the
actual date of the execution of such Warrant Certificate, shall be the proper
officer of the Company, although at the date of the execution of this Agreement
such person was not such an officer.

     Section 1.3 Issuance and Delivery of Warrant Certificates. At any time and
from time to time after the execution and delivery of this Agreement, the
Company may deliver Warrant Certificates executed by the Company to the Warrant
Agent for countersignature. Subject to the provisions of this Section 1.3, the
Warrant Agent shall thereupon countersign and deliver such Warrant Certificates
to or upon the written request of the Company. Subsequent to the original
issuance of a Stock Warrant Certificate evidencing Stock Warrants, the Warrant
Agent shall countersign a new Warrant Certificate evidencing such Stock Warrants
only if such Warrant Certificate is issued in exchange or substitution for one
or more previously countersigned Warrant Certificates evidencing such Stock
Warrants or in connection with their transfer, as hereinafter provided.

     Section 1.4 Temporary Warrant Certificates. Pending the preparation of
definitive Warrant Certificates, the Company may execute, and upon the order of
the Company the Warrant Agent shall countersign and deliver, temporary Warrant
Certificates that are printed, lithographed, typewritten, mimeographed or
otherwise produced, substantially of the tenor of the definitive Warrant
Certificates in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the officer
executing such Warrant Certificates may determine, as evidenced by his execution
of such Warrant Certificates.

     If temporary Warrant Certificates are issued, the Company will cause
definitive Warrant Certificates to be prepared without unreasonable delay. After
the preparation of definitive Warrant Certificates, the temporary Warrant
Certificates shall be exchangeable for definitive Warrant Certificates upon
surrender of the temporary Warrant Certificates at the corporate trust office of
the Warrant Agent or ______________, without charge to the Holder, as defined in
Section 1.6 hereof. Upon surrender for cancellation of any one or more temporary
Warrant Certificates, the Company shall execute and the Warrant Agent shall
countersign and deliver in exchange therefor definitive Warrant Certificates

<PAGE>

representing the same aggregate number of Stock Warrants. Until so exchanged,
the temporary Warrant Certificates shall in all respects be entitled to the same
benefits under this Agreement as definitive Warrant Certificates.

     Section 1.5 Payment of Certain Taxes. The Company will pay all stamp and
other duties, if any, to which this Agreement or the original issuance of the
Stock Warrants or Warrant Certificates may be subject under the laws of the
United States of America or any state or locality.

     Section 1.6 "Holder". The term "Holder" or "Holders" as used herein with
reference to a Warrant Certificate shall mean the person or persons in whose
name such Warrant Certificate shall then be registered as set forth in the
Warrant Register to be maintained by the Warrant Agent pursuant to Section 4.1
for that purpose.

                                   ARTICLE II

                     DURATION AND EXERCISE OF STOCK WARRANTS

     Section 2.1 Duration of Stock Warrants. Each Stock Warrant may be exercised
at the time or times, or during the period or periods, provided by or pursuant
to the Board Resolution relating thereto and specified in the Warrant
Certificate evidencing such Stock Warrant. Each Stock Warrant not exercised at
or before 5:00 P.M., New York City time, on its Expiration Date shall become
void, and all rights of the Holder of such Stock Warrant thereunder and under
this Agreement shall cease, provided that the Company reserves the right to, and
may, in its sole discretion, at any time and from time to time, at such time or
times as the Company so determines, extend the Expiration Date of the Stock
Warrants for such periods of time as it chooses. Whenever the Expiration Date of
the Stock Warrants is so extended, the Company shall at least [20] days prior to
the then Expiration Date cause to be mailed to the Warrant Agent and the
registered Holders of the Stock Warrants in accordance with the provisions of
Section 6.3 hereof a notice stating that the Expiration Date has been extended
and setting forth the new Expiration Date. No adjustment shall be made for any
dividends on any [Preferred/Common] Shares issuable upon exercise of any Stock
Warrant.

     Section 2.2 Exercise of Stock Warrants. (a) The Holder of a Stock Warrant
shall have the right, at its option, to exercise such Stock Warrant and, subject
to subsection (f) of this Section 2.2, purchase the number of [Preferred/Common]
Shares provided for therein at the time or times or during the period or periods
referred to in Section 2.1 and specified in the Warrant Certificate evidencing
such Stock Warrant. No fewer than the minimum number of Stock Warrants as set
forth in the Warrant Certificate may be exercised by or on behalf of any one
Holder at any one time. Except as may be provided in a Warrant Certificate, a
Stock Warrant may be exercised by completing the form of election to purchase
set forth on the reverse side of the Warrant Certificate, by duly executing the
same, and by delivering the same, together with payment in full of the Warrant
Price, in lawful money of the United States of America, in cash or by certified
or official bank check or by bank wire transfer, to the Warrant Agent. Except as
may be provided in a Warrant Certificate, the date on which such Warrant
Certificate and payment are received by the Warrant Agent as aforesaid shall be
deemed to be the date on which the Stock Warrant is exercised and the relevant
[Preferred/Common] Shares are issued.

     (b) Upon the exercise of a Stock Warrant, the Company shall issue to or
upon the order of the Holder of such Warrant, the [Preferred/Common] Shares to
which such Holder is entitled, registered, in the case of [Preferred/Common]
Shares in registered form, in such name or names as may be directed by such
Holder.

     (c) If fewer than all of the Stock Warrants evidenced by a Warrant
Certificate are exercised, the Company shall execute, and an authorized officer
of the Warrant Agent shall countersign and deliver, a new Warrant Certificate
evidencing the number of Stock Warrants remaining unexercised.

     (d) The Warrant Agent shall deposit all funds received by it in payment of
the Warrant Price for Stock Warrants in the account of the Company maintained
with it for such purpose and shall advise the Company by telephone by 5:00 P.M.,
New York City time, of each day on which a payment of the Warrant Price for

<PAGE>

Warrants is received of the amount so deposited in its account. The Warrant
Agent shall promptly confirm such telephone advice in writing to the Company.

     (e) The Warrant Agent shall, from time to time, as promptly as practicable,
advise the Company of (i) the number of Stock Warrants of each title exercised
as provided herein, (ii) the instructions of each Holder of such Stock Warrants
with respect to delivery of the [Preferred/Common] Shares issued upon exercise
of such Stock Warrants to which such Holder is entitled upon such exercise, and
(iii) such other information as the Company shall reasonably require. Such
notice may be given by telephone to be promptly confirmed in writing.

     (f) The Company will pay all documentary stamp taxes attributable to the
initial issuance of Stock Warrants or to the issuance of [Preferred/Common]
Shares to the registered Holder of such Stock Warrants upon exercise thereof;
provided, however, that the Holder, and not the Company, shall be required to
pay any stamp or other tax or other governmental charge that may be imposed in
connection with any transfer involved in the issuance of the [Preferred/Common]
Shares; and in the event that any such transfer is involved, the Company shall
not be required to issue any [Preferred/Common] Shares (and the Holder's
purchase of the [Preferred/Common] Shares issued upon the exercise of such
Holder's Stock Warrant shall not be deemed to have been consummated) until such
tax or other charge shall have been paid or it has been established to the
Company's satisfaction that no such tax or other charge is due.

     Section 2.3 Stock Warrant Adjustments. The terms and conditions, if any, on
which the exercise price of and/or the number of [Preferred/Common] Shares
covered by a Stock Warrant are subject to adjustments will be set forth in the
Warrant Certificate and in the Prospectus Supplement relating thereto. Such
terms may include the adjustment mechanism for the exercise price of, and the
number of [Preferred/Common] Shares covered by, a Stock Warrant, the events
requiring such adjustments, the events upon which the Company may, in lieu of
making such adjustments, make proper provisions so that the Holder, upon
exercise of such Holder's Stock Warrant, would be treated as if such Holder had
been a holder of the [Preferred/Common] Shares received upon such exercise,
prior to the occurrence of such events, and provisions affecting exercise of the
Stock Warrants in the event of certain events affecting the [Preferred/Common]
Shares.

                                   ARTICLE III

                 OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS
                                OF STOCK WARRANTS

     Section 3.1 No Rights as Holder of Underlying [Preferred/Common] Shares
Conferred by Stock Warrants or Warrant Certificates. No Stock Warrants or
Warrant Certificates shall entitle the Holder to any of the rights, preferences
and privileges of a holder of the underlying [Preferred/Common] Shares,
including without limitation, any dividend, voting, redemption, conversion,
exchange and liquidation rights.

     Section 3.2 Lost, Stolen, Destroyed or Mutilated Warrant Certificates. Upon
receipt by the Company and the Warrant Agent of evidence reasonably satisfactory
to them of the ownership of and the loss, theft, destruction or mutilation of
any Warrant Certificate and of indemnity (other than in connection with any
mutilated Warrant Certificates surrendered to the Warrant Agent for
cancellation) reasonably satisfactory to them, the Company shall execute, and
Warrant Agent shall countersign and deliver, in exchange for or in lieu of each
lost, stolen, destroyed or mutilated Warrant Certificate, a new Warrant
Certificate evidencing a like number of Stock Warrants of the same title. Upon
the issuance of a new Warrant Certificate under this Section, the Company may
require the payment of a sum sufficient to cover any stamp or other tax or other
governmental charge that may be imposed in connection therewith and any other
expenses (including the fees and expenses of the Warrant Agent) in connection
therewith. Every substitute Warrant Certificate executed and delivered pursuant
to this Section in lieu of any lost, stolen or destroyed Warrant Certificate
shall represent a contractual obligation of the Company, whether or not such
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, evidencing Stock Warrants of the same title. The provisions

<PAGE>

of this Section are exclusive and shall preclude (to the extent lawful) all
other rights and remedies with respect to the replacement of lost, stolen,
destroyed or mutilated Warrant Certificates.

     Section 3.3 Holders of Stock Warrants May Enforce Rights. Notwithstanding
any of the provisions of this Agreement, any Holder may, without the consent of
the Warrant Agent, enforce and may institute and maintain any suit, action or
proceeding against the Company suitable to enforce, or otherwise in respect of,
its right to exercise his Stock Warrants as provided in the Stock Warrants and
in this Agreement.

     Section 3.4 Merger, Consolidation, Sale, Transfer or Conveyance. (a) In
case any of the following shall occur while any Stock Warrants are outstanding:
(i) any reclassification or change of the outstanding [Preferred/Common] Shares;
or (ii) any consolidation or merger to which the Company is party (other than a
consolidation or a merger in which the Company is the continuing corporation and
which does not result in any reclassification of, or change in, the outstanding
[Preferred/Common] Shares issuable upon exercise of the Stock Warrants); or
(iii) any sale, conveyance or lease to another corporation of the property of
the Company as an entirety or substantially as an entirety; then the Company, or
such successor or purchasing corporation, as the case may be, shall make
appropriate provision by amendment of this Agreement or otherwise so that the
Holders of the Stock Warrants then outstanding shall have the right at any time
thereafter, upon exercise of such Stock Warrants, to purchase the kind and
amount of capital shares and other securities and property receivable upon such
a reclassification, change, consolidation, merger, sale, conveyance or lease as
would be received by a holder of the number of [Preferred/Common] Shares
issuable upon exercise of such Stock Warrant immediately prior to such
reclassification, change, consolidation, merger, sale, conveyance or lease, and,
in the case of a consolidation, merger, sale, conveyance or lease, the Company
shall thereupon be relieved of any further obligation hereunder or under the
Stock Warrants, and the Company as the predecessor corporation may thereupon or
at any time thereafter be dissolved, wound up or liquidated. Such successor or
assuming corporation thereupon may cause to be signed, and may issue either in
its own name or in the name of the Company, any of all of the Stock Warrants
issuable hereunder which theretofore shall not have been signed by the Company,
and may execute and deliver [Preferred/Common] Shares in its own name, in
fulfillment of its obligations to deliver Shares upon exercise of the Stock
Warrants. All the Stock Warrants so issued shall in all respects have the same
legal rank and benefit under this Agreement as the Stock Warrants theretofore or
thereafter issued in accordance with the terms of this Agreement as though all
of such Stock Warrants had been issued at the date of the execution hereof. In
any case of any such reclassification, change, consolidation, merger,
conveyance, transfer or lease, such changes in phraseology and form (but not in
substance) may be made in the Stock Warrants thereafter to be issued as may be
appropriate.

     (b) If reasonably requested by the Stock Warrant Agent, the Stock Warrant
Agent shall receive a written opinion of legal counsel as conclusive evidence
that any such merger, consolidation, sale, transfer, conveyance or other
disposition of substantially all of the assets of the Company complies with the
provisions of this Section 3.4.

                                   ARTICLE IV

                     EXCHANGE AND TRANSFER OF STOCK WARRANTS

     Section 4.1 Stock Warrant Register; Exchange and Transfer of Stock
Warrants. The Warrant Agent shall maintain, at its corporate trust office or at
_________, a register (the "Warrant Register") in which, upon the issuance of
Stock Warrants and, subject to such reasonable regulations as the Warrant Agent
may prescribe, it shall register Warrant Certificates and exchanges and
transfers thereof. The Warrant Register shall be in written form or in any other
form capable of being converted into written form within a reasonable time.

     Except as provided in the following sentence, upon surrender at the
corporate trust office of the Warrant Agent or at _________ Warrant Certificates
may be exchanged for one or more other Warrant Certificates evidencing the same
aggregate number of Stock Warrants of the same title, or may be transferred in
whole or in part. A transfer shall be registered upon surrender of a Warrant

<PAGE>

Certificate to the Warrant Agent at its corporate trust office or at __________
for transfer, properly endorsed or accompanied by appropriate instruments of
transfer and written instructions for transfer, all in form satisfactory to the
Company and the Warrant Agent, duly signed by the registered holder or holders
thereof or by the duly appointed legal representative thereof or by a duly
authorized attorney, such signature to be guaranteed by (a) a bank or trust
company, (b) a broker or dealer that is a member of the National Association of
Securities Dealers, Inc. (the "NASD") or (c) a member of a national securities
exchange. Upon any such registration of transfer, a new Warrant Certificate
shall be issued to the transferee. Whenever a Warrant Certificate is surrendered
for exchange or transfer, the Warrant Agent shall countersign and deliver to the
person or persons entitled thereto one or more Warrant Certificates duly
executed by the Company, as so requested. The Stock Warrant Agent shall not be
required to effect any exchange or transfer which will result in the issuance of
a Warrant Certificate evidencing a fraction of a Stock Warrant. All Warrant
Certificates issued upon any exchange or transfer of a Warrant Certificate shall
be the valid obligations of the Company, evidencing the same obligations, and
entitled to the same benefits under this Agreement, as the Warrant Certificate
surrendered for such exchange or transfer.

     No service charge shall be made for any exchange or transfer of Stock
Warrants, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any such
exchange or transfer, in accordance with Section 2.2(f) hereof.

     Section 4.2 Treatment of Holders of Warrant Certificates. The Company and
the Warrant Agent may treat the registered Holder of a Warrant Certificate as
the absolute Holder thereof for any purpose and as the person entitled to
exercise the rights represented by the Stock Warrants evidenced thereby, any
notice to the contrary notwithstanding.

     Section 4.3 Cancellation of Warrant Certificates. In the event that the
Company shall purchase, redeem or otherwise acquire any Stock Warrants after the
issuance thereof, the Warrant Certificate or Warrant Certificates evidencing
such Stock Warrants shall thereupon be delivered to the Warrant Agent and be
cancelled by it. The Warrant Agent shall also cancel any Warrant Certificate
(including any Warrant Certificate) delivered to it for exercise, in whole or in
part, or for exchange or transfer. Warrant Certificates so cancelled shall be
delivered by the Warrant Agent to the Company from time to time, or disposed of
in accordance with the instructions of the Company.

                                    ARTICLE V

                          CONCERNING THE WARRANT AGENT

     Section 5.1 Warrant Agent. The Company hereby appoints __________________
as Warrant Agent of the Company in respect of the Stock Warrants upon the terms
and subject to the conditions set forth herein, and __________________ hereby
accepts such appointment. The Warrant Agent shall have the powers and authority
granted to and conferred upon it in the Warrant Certificates and hereby, 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 of 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.

     Section 5.2 Conditions of Warrant Agent's Obligations. The Warrant Agent
accepts its obligations set forth herein upon the terms and conditions hereof,
including the following, to all of which the Company agrees and to all of which
the rights hereunder of the Holders shall be subject:

     (a) Compensation and Indemnification. The Company agrees to promptly pay
the Warrant Agent the compensation set forth in Exhibit A hereto and to
reimburse the Warrant Agent for reasonable out-of-pocket expenses (including
counsel fees) incurred by the Warrant Agent in connection with the services
rendered hereunder by the Warrant Agent. The Company also agrees to indemnify
the Warrant Agent for, and to hold it harmless against, any loss, liability or
expense (including the reasonable costs and expenses of defending against any
claim of liability) incurred without negligence or bad faith on the part of the
Warrant Agent arising out of or in connection with its appointment, status or

<PAGE>

service as Warrant Agent hereunder.

     (b) Agent for the Company. In acting under this Agreement and in connection
with any Warrant Certificate, the Warrant Agent is acting solely as agent of the
Company and does not assume any obligation or relationship of agency or trust
for or with any Holder.

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

     (d) Documents. The Warrant Agent shall be protected and shall incur no
liability for or in respect of any action taken, suffered or omitted by it in
reliance upon any notice, direction, consent, certificate, affidavit, statement
or other paper or document reasonably believed by it to be genuine and to have
been presented or signed by the proper parties.

     (e) Officer's Certificate. Whenever in the performance of its duties
hereunder the Warrant Agent shall reasonably deem it necessary that any fact or
matter be proved or established by the Company prior to taking, suffering or
omitting any action hereunder, the Warrant Agent may (unless other evidence in
respect thereof be herein specifically prescribed), in the absence of bad faith
on its part, rely upon a certificate signed by the Chairman of the Board of
Directors, the Vice Chairman of the Board of Directors, the President, an
Executive Vice President, the Treasurer, an Assistant Treasurer, the Secretary
or an Assistant Secretary of the Company (an "Officer's Certificate") delivered
by the Company to the Warrant Agent.

     (f) Actions Through Agents. The Warrant Agent may execute and exercise any
of the rights or powers hereby vested in it or perform any duty hereunder either
itself or by or through its attorneys or agents, and the Warrant Agent shall not
be answerable or accountable for any act, default, neglect or misconduct of any
such attorney or agent or for any loss to the Company resulting from such
neglect or misconduct; provided, however, that reasonable care shall have been
exercised in the selection and continued employment of such attorneys and
agents.

     (g) Certain Transactions. The Warrant Agent, and any officer, director or
employee thereof, may become the owner of, or acquire any interest in, any Stock
Warrant, with the same rights that he, she or it would have if it were not the
Warrant Agent, and, to the extent permitted by applicable law, he, she or it may
engage or be interested in any financial or other transaction with the Company
and may serve on, or as depository, trustee or agent for, any committee or body
of holders of [Preferred/Common] Shares or other obligations of the Company as
if it were not the Warrant Agent.

     (h) No Liability For Interest. The Warrant Agent shall not be liable for
interest on any monies at any time received by it pursuant to any of the
provisions of this Agreement or of the Warrant Certificates, except as otherwise
agreed with the Company.

     (i) No Liability For Invalidity. The Warrant Agent shall incur no liability
with respect to the validity of this Agreement (except as to the due execution
hereof by the Warrant Agent) or any Warrant Certificate (except as to the
countersignature thereof by the Warrant Agent).

     (j) No Responsibility For Company Representations. The Warrant Agent shall
not be responsible for any of the recitals or representations contained herein
(except as to such statements or recitals as describe the Warrant Agent or
action taken or to be taken by it) or in any Warrant Certificate (except as to
the Warrant Agent's countersignature on such Warrant Certificate), all of which
recitals and representations are made solely by the Company.

     (k) No Implied Obligations. The Warrant Agent shall be obligated to perform
only such duties as are specifically set forth herein, and no other duties or
obligations shall be implied. The Warrant Agent shall not be under any
obligation to take any action hereunder that may subject it to any expense or
liability, the payment of which within a reasonable time is not, in its
reasonable opinion, assured to it. The Warrant Agent shall not be accountable or

<PAGE>

under any duty or responsibility for the use by the Company of any Warrant
Certificate countersigned by the Warrant Agent and delivered by it to the
Company pursuant to this Agreement or for the application by the Company of the
proceeds of the issuance or exercise of Stock Warrants. The Warrant Agent shall
have no duty or responsibility in case of any default by the Company in the
performance of its covenants or agreements contained herein or in any Warrant
Certificate or in case of the receipt of any written demand from a Holder with
respect to such default, including, without limiting the generality of the
foregoing, any duty or responsibility to initiate or attempt to initiate any
proceedings at law or otherwise or, except as provided in Section 6.2 hereof, to
make any demand upon the Company.

     Section 5.3 Resignation and Removal; Appointment of Successor. (a) The
Company agrees, for the benefit of the Holders of the Stock Warrants, that there
shall at all times be a Warrant Agent hereunder until all the Stock Warrants are
no longer exercisable.

     (b) The Warrant Agent may at any time resign as such by giving written
notice to the Company, specifying the date on which its desired resignation
shall become effective; provided that such date shall not be less than [90] days
after the date on which such notice if given unless the Company agrees to accept
a shorter notice. The Warrant Agent hereunder may be removed at any time by the
filing with it of an instrument in writing signed by or on behalf of the Company
and specifying such removal and the date when it shall become effective.
Notwithstanding the provisions of this Section 5.3(b), such resignation or
removal shall take effect upon the appointment by the Company, as hereinafter
provided, of a successor Warrant Agent (which shall be a banking institution
organized and doing business under the laws of the United States of America, any
State thereof or the District of Columbia, authorized under the laws of such
jurisdiction to exercise corporate trust powers and having at the time of its
appointment as Warrant Agent a combined capital and surplus (as set forth in its
most recent published report of financial condition) of at least
[$50,000,000])and the acceptance of such appointment by such successor Warrant
Agent. In the event a successor Warrant Agent has not been appointed and has not
accepted its duties within [90] days of the Warrant Agent's notice of
resignation, the Warrant Agent may apply to any court of competent jurisdiction
for the designation of a successor Warrant Agent. The obligations of the Company
under Section 5.02(a) shall continue to the extent set forth therein
notwithstanding the resignation or removal of the Warrant Agent.

     (c) In case at any time the Warrant Agent shall resign, or shall be
removed, or shall become incapable of acting, or shall file a petition seeking
relief under Title 11 of the United States Code, as now constituted or hereafter
amended or under any other applicable federal or state bankruptcy law or similar
law, or make an assignment for the benefit of its creditors or consent to the
appointment of a receiver or custodian of all or any substantial part of its
property, or shall admit in writing its inability to pay or meet its debts as
they mature, or if a receiver or custodian of it or all or any substantial part
of its property shall be appointed, or if an order of any court shall be entered
for relief against it under the provisions of Title 11 of the United States
Code, as now constituted or hereafter amended, or under any other applicable
federal or state bankruptcy or similar law, or if any public officer shall have
taken charge or control of the Warrant Agent or of its property or affairs, for
the purpose of rehabilitation, conservation or liquidation, a successor Warrant
Agent, qualified as aforesaid, 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 the
latter of such appointment, the Warrant Agent so superseded shall cease to be
Warrant Agent hereunder.

     (d) Any successor Warrant Agent appointed hereunder shall execute,
acknowledge and deliver to its predecessor and to the Company an instrument
accepting such appointment hereunder, and thereupon such successor Warrant
Agent, without any further act, deed or conveyance, shall become vested with all
the authority, rights, powers, trusts, immunities, duties and obligations of
such predecessor with like effect as if originally named as Warrant Agent
hereunder, and such predecessor, upon payment of its charges and disbursements
then unpaid, shall thereupon become obligated to transfer, deliver and pay over,
and such successor Warrant Agent shall be entitled to receive all moneys,
securities and other property on deposit with or held by such predecessor, as

<PAGE>

Warrant Agent hereunder.

     (e) Any corporation into which the Warrant Agent hereunder may be merged or
converted or any corporation with which the Warrant Agent may be consolidated,
or any corporation resulting from any merger, conversion or consolidation to
which the Warrant Agent shall be a party, or any corporation to which the
Warrant Agent shall sell or otherwise transfer all or substantially all of the
assets and business of the Warrant Agent, provided that such Corporation shall
be qualified as aforesaid, shall be the successor Warrant Agent under this
Agreement without the execution or filing of any paper or any further act on the
part of any of the parties hereto.

     Section 5.4 Compliance With Applicable Laws. The Warrant Agent agrees to
comply with all applicable federal and state laws imposing obligations on it in
respect of the services rendered by it under this Warrant Agreement and in
connection with the Stock Warrants, including (but not limited to) the
provisions of United States federal income tax laws regarding information
reporting and backup withholding. The Warrant Agent expressly assumes all
liability for its failure to comply with any such laws imposing obligations on
it, including (but not limited to) any liability for failure to comply with any
applicable provisions of United States federal income tax laws regarding
information reporting and backup withholding.

     Section 5.5 Office. The Company will maintain an office or agency where
Warrant Certificates may be presented for exchange, transfer or exercise. The
office initially designated for this purpose shall be the corporate trust office
of the Warrant Agent at ________________.

                                  MISCELLANEOUS

     Section 6.1 Supplements and Amendments. (a) The Company and Warrant Agent
may from time to time supplement or amend this Agreement without the approval or
consent of any Holder in order to cure any ambiguity, to correct or supplement
any provision contained herein that may be defective or inconsistent with any
other provisions herein, or to make any other provision in regard to matters or
questions arising hereunder that the Company and the Warrant Agent may deem
necessary or desirable and that shall not adversely affect the interests of the
Holders. Every Holder of Stock Warrants, whether issued before or after any such
supplement or amendment, shall be bound thereby. Promptly after the
effectiveness of any supplement or amendment that affects the interest of the
Holders, the Company shall give notice thereof, as provided in Section 6.3
hereof, to the Holders affected thereby, setting forth in general terms the
substance of such supplement or amendment.

     (b) The Company and the Warrant Agent may modify or amend this Agreement
and the Warrant Certificates with the consent of the Holders of not fewer than a
majority in number of the underlying [Preferred/Common] Shares affected by such
modification or amendment, for any purpose; provided, however, that no such
modification or amendment that shortens the period of time during which the
Stock Warrants may be exercised, or otherwise materially and adversely affects
the exercise rights of the Holders or reduces the percentage of Holders of
outstanding Stock Warrants the consent of which is required for modification or
amendment of this Agreement or the Stock Warrants, may be made without the
consent of each Holder affected thereby.

     Section 6.2 Notices and Demands to the Company and Warrant Agent. If the

Holder pursuant to the provisions of the Warrant Certificates, the Warrant Agent

Warrants and Warrant Certificates, the exercise of the Stock Warrants and the
issuance, sale and delivery of the underlying [Preferred/Common] Shares issued
upon the exercise of the Stock Warrants.

     Section 6.6 Persons Having Rights Under Stock Warrant Agreement. Nothing in
this Agreement expressed or implied and nothing that may be inferred from any of
the provisions hereof is intended, or shall be construed, to confer upon, or
give to, any person or corporation other than the Company, the Warrant Agent and
the Holders any right, remedy or claim under or by reason of this Agreement or
of any covenant, condition, stipulation, promise or agreement hereof; and all
covenants, conditions, stipulations, promises and agreements in this Agreement
contained shall be for the sole and exclusive benefit of the Company and the
Warrant Agent and their respective successors and of the Holders of Warrant
Certificates.

     Section 6.7 Delivery of Prospectus/Prospectus Supplement. The Company will
furnish to the Warrant Agent sufficient copies of a prospectus, prospectus
supplement or prospectuses relating to the [Preferred/Common] Shares deliverable
upon exercise of any outstanding Stock Warrants (each a "Prospectus"), and prior

another corporation or other entity, or convey or transfer all or substantially
all of its properties and assets to any other corporation or other entity.]

     Section 6.12 Rights and Duties of Successor Corporation. In case of any
such consolidation, merger, conveyance or transfer and upon any assumption of
the duties and obligations of the Company by the successor corporation, such
successor corporation shall succeed to and be substituted for the Company, with
the same effect as if it had been named herein, and the Company shall be
relieved of any further obligation under this Agreement and the Stock Warrants.

changes in phraseology and form (but not in substance) may be made in the
Preferred Shares thereafter to be issued as may be appropriate.
