     WHEREAS, all requirements necessary to make this Indenture a valid

and shall include the plural as well as the singular.  All other terms used
in this Indenture that are defined in the Trust Indenture Act, or that are by
reference in the Trust Indenture Act defined in the Securities Act (except as

in the Securities Act as in force at the date of the execution of this
instrument. All accounting terms used herein and not expressly defined shall
have the meanings assigned to such terms in accordance with Generally Accepted

in respect of Senior Debt or Subordinated Debt or obligations which, by their
terms, are expressly stated to be not superior in right of payment to the
Debentures or to rank pari passu in right of payment with the Debentures.  For
purposes of this definition, "claim" shall have the meaning assigned thereto in
Section 101(4) of the United States Bankruptcy Code of 1978, as amended.

     "Administrative Trustees" shall have the meaning set forth in the Trust
Agreement.

or an Assistant Secretary of the Company to have been duly adopted by the Board
of Directors and to be in full force and effect on the date of such
certification.

     "Business Day" means, with respect to the Debentures, any day other than a

     "Capital Treatment Event" means the receipt by the Trust of an Opinion of
Counsel, rendered by a law firm having a recognized banking law practice, to
the effect that, as a result of any amendment to, or change (including any
announced prospective change) in, the laws (or any regulations thereunder) of

result of any official administrative pronouncement or judicial decision
interpreting or applying such laws or regulations, which amendment or change is
effective or such proposed change, pronouncement or decision is announced on or
after the date of issuance of the Preferred Securities under the Trust

fully protected in relying upon, an Opinion of Counsel stating that the form

this Indenture.

     Pending the preparation of definitive Debentures, the Company may execute,
and the Trustee shall authenticate and deliver, temporary Debentures (printed,
lithographed, or typewritten).  Such temporary Debentures shall be
substantially in the form of the definitive Debentures in lieu of which they
are issued, but with such omissions, 


   19



insertions and variations as may be appropriate for temporary Debentures,
all as may be determined by the Company. Every temporary Debenture shall be
executed by the Company and be authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with like effect, as the
definitive Debentures.  Without unnecessary delay the Company shall execute and
shall furnish definitive Debentures and thereupon any or all temporary
Debentures may be surrendered in exchange therefor (without charge to the
holders), at the office or agency of the Company designated for the purpose, and
the Trustee shall authenticate and such office or agency shall deliver in
exchange for such temporary Debentures an equal aggregate principal amount of
definitive Debentures, unless the Company advises the Trustee to the effect that
definitive Debentures need not be executed and furnished until further notice
from the Company.  Until so exchanged, the temporary Debentures shall be
entitled to the same benefits under this Indenture as definitive Debentures
authenticated and delivered hereunder.

SECTION 2.9.    MUTILATED, DESTROYED, LOST OR STOLEN
                DEBENTURES.

     (a)  In case any temporary or definitive Debenture shall become mutilated
or be destroyed, lost or stolen, the Company (subject to the next succeeding
sentence) shall execute, and upon the Company's request the Trustee (subject as
aforesaid) shall authenticate and deliver, a new Debenture bearing a
number not contemporaneously outstanding, in exchange and substitution for the
mutilated Debenture, or in lieu of and in substitution for the Debenture so
destroyed, lost or stolen.  In every case the applicant for a substituted
Debenture shall furnish to the Company and the Trustee such security or
indemnity as may be required by them to save each of them harmless, and, in
every case of destruction, loss or theft, the applicant shall also furnish to
the Company and the Trustee evidence to their satisfaction of the destruction,
loss or theft of the applicant's Debenture and of the ownership thereof.  The
Trustee may authenticate any such substituted Debenture and deliver the same
upon the written request or authorization of the Chairman, President or any
Vice-President and the Treasurer or any Assistant Treasurer of the Company. 
Upon the issuance of any substituted Debenture, 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 Trustee) connected therewith.  In case any Debenture that
has matured or is about to mature shall become mutilated or be destroyed, lost
or stolen, the Company may, instead of issuing a substitute Debenture, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated Debenture) if the applicant for such payment shall furnish to the
Company and the Trustee such security or indemnity as they may require to save
them harmless, and, in case of destruction, loss or theft, evidence to the
satisfaction of the Company and the Trustee of the destruction, loss or theft of
such Debenture and of the ownership thereof.

     (b)  Every replacement Debenture issued pursuant to the provisions of this
Section 2.9 shall constitute an additional contractual obligation of the
Company whether or not the mutilated, destroyed, lost or stolen Debenture shall
be found at any time, or be enforceable by anyone, and shall be entitled to all
the benefits of this Indenture 


   20


equally and proportionately with any and all other Debentures duly issued
hereunder.  All Debentures shall be held and owned upon the express condition
that the foregoing provisions are exclusive with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Debentures, and shall preclude
(to the extent lawful) any and all other rights or remedies, notwithstanding any
law or statute existing or hereafter enacted to the contrary with respect to the
replacement or payment of negotiable instruments or other securities without
their surrender.

SECTION 2.10.   CANCELLATION.

     All Debentures surrendered for the purpose of payment, redemption,
exchange or registration of transfer shall, if surrendered to the Company or
any paying agent, be delivered to the Trustee for cancellation, or, if
surrendered to the Trustee, shall be canceled by it, and no Debentures shall be
issued in lieu thereof except as expressly required or permitted by any of the
provisions of this Indenture.  On request of the Company at the time of such
surrender, the Trustee shall deliver to the Company canceled Debentures held by
the Trustee.  In the absence of such request the Trustee may dispose of
canceled Debentures in accordance with its standard procedures and deliver
a certificate of disposition to the Company.  If the Company shall otherwise
acquire any of the Debentures, however, such acquisition shall not operate as a
redemption or satisfaction of the indebtedness represented by such Debentures
unless and until the same are delivered to the Trustee for cancellation.

SECTION 2.11.   BENEFIT OF INDENTURE.

     Nothing in this Indenture or in the Debentures, express or implied, shall
give or be construed to give to any Person, other than the parties hereto and
the holders of the Debentures (and, with respect to the provisions of Article
XVI, the holders of Senior Indebtedness) any legal or equitable right, remedy
or claim under or in respect of this Indenture, or under any covenant,
condition or provision herein contained; all such covenants, conditions and
provisions being for the sole benefit of the parties hereto and of the holders
of the Debentures (and, with respect to the provisions of Article XVI, the
holders of Senior Indebtedness).

SECTION 2.12.   AUTHENTICATION AGENT.

     (a)  So long as any of the Debentures remain Outstanding there may be an
Authenticating Agent for any or all such Debentures, which the Trustee shall
have the right to appoint.  Said Authenticating Agent shall be authorized to
act on behalf of the Trustee to authenticate Debentures issued upon exchange,
transfer or partial redemption thereof, and Debentures so authenticated shall
be entitled to the benefits of this Indenture and shall be valid and obligatory
for all purposes as if authenticated by the Trustee hereunder.  All references
in this Indenture to the authentication of Debentures by the Trustee shall be
deemed to include authentication by an Authenticating Agent.  Each
Authenticating Agent shall be acceptable to the Company and shall be a
corporation that has a combined capital and surplus, as most recently reported
or determined by it, sufficient under the laws of any jurisdiction under which
it is organized or in which it is doing 


   21


business to conduct a trust business, and that is otherwise authorized under
such laws to conduct such business and is subject to supervision or examination
by federal or state authorities.  If at any time any Authenticating Agent shall
cease to be eligible in accordance with these provisions, it shall resign
immediately.

     (b)  Any Authenticating Agent may at any time resign by giving written
notice of resignation to the Trustee and to the Company.  The Trustee may at
any time (and upon request by the Company shall) terminate the agency of any
Authenticating Agent by giving written notice of termination to such
Authenticating Agent and to the Company.  Upon resignation, termination or
cessation of eligibility of any Authenticating Agent, the Trustee may appoint
an eligible successor Authenticating Agent acceptable to the Company.  Any
successor Authenticating Agent, upon acceptance of its appointment hereunder,
shall become vested with all the rights, powers and duties of its predecessor
hereunder as if originally named as an Authenticating Agent pursuant hereto.


                                 ARTICLE III.
                           REDEMPTION OF DEBENTURES

SECTION 3.1.    REDEMPTION.

     Subject to the Company having received prior approval of the Federal
Reserve, if then required under the applicable capital guidelines or policies
of the Federal Reserve, the Company may redeem the Debentures issued hereunder
on and after the dates set forth in and in accordance with the terms of this
Article III.

SECTION 3.2.    SPECIAL EVENT REDEMPTION.

     Subject to the Company having received the prior approval of the Federal
Reserve, if then required under the applicable capital guidelines or policies
of the Federal Reserve, if a Special Event has occurred and is continuing,
then, notwithstanding Section 3.3, the Company shall have the right upon not
less than 30 days nor more than 60 days notice to the holders of the Debentures
to redeem the Debentures, in whole but not in part, for cash within 180 days
following the occurrence of such Special Event (the "180-Day Period") at a
redemption price equal to 100% of the principal amount to be redeemed plus any
accrued and unpaid interest thereon to the date of such redemption (the
"Redemption Price"), provided that if at the time there is available to the
Company the opportunity to eliminate, within the 180-Day Period, a Tax Event by
taking some ministerial action (a "Ministerial Action"), such as filing a form
or making an election, or pursuing some other similar reasonable measure which
has no adverse effect on the Company, the Trust or the holders of the Trust
Securities issued by the Trust, the Company shall pursue such Ministerial
Action in lieu of redemption, and, provided further, that the Company shall
have no right to redeem the Debentures while it is pursuing any Ministerial
Action pursuant to its obligations hereunder, and, provided
further, that, if it is determined that the taking of a Ministerial Action
would not eliminate the Tax Event within the 180-Day Period, the Company's
right to redeem the Debentures shall be restored and it shall have no further
obligations to pursue the Ministerial Action.  The Redemption Price shall be
paid prior to 12:00 noon, New York time, on 


   22



the date of such redemption or such earlier time as the Company determines,
provided that the Company shall deposit with the Trustee an amount sufficient to
pay the Redemption Price by 10:00 a.m., New York time, on the date such
Redemption Price is to be paid.

SECTION 3.3.    OPTIONAL REDEMPTION BY COMPANY.

     (a)  Subject to the provisions of Section 3.3(b), except as otherwise may
be specified in this Indenture, the Company shall have the right to redeem the
Debentures, in whole or in part, from time to time, on or after December 31,
2002, at a Redemption Price equal to 100% of the principal amount to be
redeemed plus any accrued and unpaid interest thereon to the date of such
redemption. Any redemption pursuant to this Section 3.3(a) shall be made upon
not less than 30 days nor more than 60 days notice to the holder of the
Debentures, at the Redemption Price.  If the Debentures are only partially
redeemed pursuant to this Section 3.3, the Debentures shall be redeemed
pro rata or by lot or in such other manner as the Trustee shall deem appropriate
and fair in its discretion.  The Redemption Price shall be paid prior to 12:00
noon, New York time, on the date of such redemption or at such earlier time as
the Company determines provided that the Company shall deposit with the Trustee
an amount sufficient to pay the Redemption Price by 10:00 a.m., New York time,
on the date such Redemption Price is to be paid.

     (b)  If a partial redemption of the Debentures would result in the
delisting of the Preferred Securities issued by the Trust from The Nasdaq Stock
Market's National Market or any comparable level or successor listing or any
national securities exchange or other organization on which the Preferred
Securities are then listed or quoted, the Company shall not be permitted to
effect such partial redemption and may only redeem the Debentures in whole.

SECTION 3.4.    NOTICE OF REDEMPTION.

     (a)  In case the Company shall desire to exercise such right to redeem all
or, as the case may be, a portion of the Debentures in accordance with the
right reserved so to do, the Company shall, or shall cause the Trustee to upon
receipt of 45 days' written notice from the Company (which notice shall, in the
event of a partial redemption, include a representation to the effect that such
partial redemption shall not result in the delisting of the Preferred
Securities as described in Section 3.3(b) above), give notice of such
redemption to holders of the Debentures to be redeemed by mailing, first class
postage prepaid, a notice of such redemption not less than 30 days and not more
than 60 days before the date fixed for redemption to such holders at their last
addresses as they shall appear upon the Debenture Register unless a shorter
period is specified in the Debentures to be redeemed.  Any notice that is
mailed in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not the registered holder receives the notice.  In
any case, failure duly to give such notice to the holder of any Debenture
designated for redemption in whole or in part, or any defect in the notice,
shall not affect the validity of the proceedings for the redemption of any
other Debentures.  In the case of any redemption of Debentures prior to the
expiration of any restriction on such redemption provided in the terms of such
Debentures or elsewhere in this Indenture, the Company shall 


   23

furnish the Trustee with an Officers' Certificate evidencing compliance with
any such restriction.  Each such notice of redemption shall specify the date
fixed for redemption and the Redemption Price and shall state that payment of
the Redemption Price shall be made at the Corporate Trust Office, upon
presentation and surrender of such Debentures, that interest accrued to the date
fixed for redemption shall be paid as specified in said notice and that from and
after said date interest shall cease to accrue.  If less than all the Debentures
are to be redeemed, the notice to the holders of the Debentures shall specify
the particular Debentures to be redeemed.  If the Debentures are to be redeemed
in part only, the notice shall state the portion of the principal amount thereof
to be redeemed and shall state that on and after the redemption date, upon
surrender of such Debenture, a new Debenture or Debentures in principal amount
equal to the unredeemed portion thereof shall be issued.

     (b)  If less than all the Debentures are to be redeemed, the Company shall
give the Trustee at least 45 days' notice in advance of the date fixed for
redemption as to the aggregate principal amount of Debentures to be redeemed,
and thereupon the Trustee shall select, by lot or in such other manner as it
shall deem appropriate and fair in its discretion, the portion or portions
(equal to the minimum authorized denomination of the Debentures or any integral
multiple thereof) of the Debentures to be redeemed and shall thereafter
promptly notify the Company in writing of the numbers of the Debentures to be
redeemed, in whole or in part.  The Company may, if and whenever it shall so
elect pursuant to the terms hereof, by delivery of instructions signed on its
behalf by its President or any Vice President, instruct the Trustee or any
paying agent to call all or any part of the Debentures for redemption and to
give notice of redemption in the manner set forth in this Section 3.4, such
notice to be in the name of the Company or its own name as the Trustee or such
paying agent may deem advisable.  In any case in which notice of redemption is
to be given by the Trustee or any such paying agent, the Company shall deliver
or cause to be delivered to, or permit to remain with, the Trustee or such
paying agent, as the case may be, such Debenture Register, transfer books or
other records, or suitable copies or extracts therefrom, sufficient to enable
the Trustee or such paying agent to give any notice by mail that may be required
under the provisions of this Section 3.4.

SECTION 3.5.    PAYMENT UPON REDEMPTION.

     (a)  If the giving of notice of redemption shall have been completed as
above provided, the Debentures or portions of Debentures to be redeemed
specified in such notice shall become due and payable on the date and at the
place stated in such notice at the applicable Redemption Price, and interest on
such Debentures or portions of Debentures shall cease to accrue on and after
the date fixed for redemption, unless the Company shall default in the payment
of such Redemption Price with respect to any such Debenture or portion thereof.
On presentation and surrender of such Debentures on or after the date fixed
for redemption at the place of payment specified in the notice, said Debentures
shall be paid and redeemed at the Redemption Price (but if the date fixed for
redemption is an interest payment date, the interest installment payable on
such date shall be payable to the 



   24

registered holder at the close of business on the applicable record date
pursuant to Section 3.3).

     (b)  Upon presentation of any Debenture that is to be redeemed in part
only, the Company shall execute and the Trustee shall authenticate and the
office or agency where the Debenture is presented shall deliver to the holder
thereof, at the expense of the Company, a new Debenture of authorized
denomination in principal amount equal to the unredeemed portion of the
Debenture so presented.

SECTION 3.6.    NO SINKING FUND.

     The Debentures are not entitled to the benefit of any sinking fund.


                                 ARTICLE IV.
                     EXTENSION OF INTEREST PAYMENT PERIOD

SECTION 4.1.    EXTENSION OF INTEREST PAYMENT PERIOD.

     So long as no Event of Default has occurred and is continuing, the Company
shall have the right, at any time and from time to time during the term of the
Debentures, to defer payments of interest by extending the interest payment
period of such Debentures for a period not exceeding 20 consecutive quarters
(the "Extended Interest Payment Period"), during which Extended Interest
Payment Period no interest shall be due and payable; provided that no Extended
Interest Payment Period may extend beyond the Maturity Date.  Interest, the
payment of which has been deferred because of the extension of the interest
payment period pursuant to this Section 4.1, shall bear interest thereon at the
Coupon Rate compounded quarterly for each quarter of the Extended Interest
Payment Period (the "Compounded Interest").  At the end of the Extended
Interest Payment Period, the Company shall calculate (and deliver such
calculation to the Trustee) and pay all interest accrued and unpaid on the
Debentures, including any Additional Payments and Compounded Interest
(together, the "Deferred Payments") that shall be payable to the holders of the
Debentures in whose names the Debentures are registered in the Debenture
Register on the first record date after the end of the Extended Interest Payment
Period.  Before the termination of any Extended Interest Payment Period, the
Company may further extend such period, provided that such period together with
all such further extensions thereof shall not exceed 20 consecutive quarters, or
extend beyond the Maturity Date of the Debentures. Upon the termination of any
Extended Interest Payment Period and upon the payment of all Deferred Payments
then due, the Company may commence a new Extended Interest Payment Period,
subject to the foregoing requirements. No interest shall be due and payable
during an Extended Interest Payment Period, except at the end thereof, but the
Company may prepay at any time all or any portion of the interest accrued during
an Extended Interest Payment Period.

SECTION 4.2.    NOTICE OF EXTENSION.

     (a)  If the Property Trustee is the only registered holder of the
Debentures at the time the Company selects an Extended Interest Payment Period,
the Company shall give written notice to the Administrative Trustees, the
Property Trustee and the Trustee of its selection of such 



   25


Extended Interest Payment Period two Business Days before the earlier of
(i) the next succeeding date on which Distributions on the Trust Securities
issued by the Trust are payable; or (ii) the date the Trust is required to give
notice of the record date, or the date such Distributions are payable, to The
Nasdaq Stock Market's National Market or other applicable self-regulatory
organization or to holders of the Preferred Securities issued by the Trust, but
in any event at least one Business Day before such record date.

     (b)  If the Property Trustee is not the only holder of the Debentures at
the time the Company selects an Extended Interest Payment Period, the Company
shall give the holders of the Debentures and the Trustee written notice
of its selection of such Extended Interest Payment Period at least two Business
Days before the earlier of (i) the next succeeding Interest Payment Date; or
(ii) the date the Company is required to give notice of the record or payment
date of such interest payment to The Nasdaq Stock Market's National Market or
other applicable self-regulatory organization or to holders of the Debentures.

     (c)  The quarter in which any notice is given pursuant to paragraphs (a)
or (b) of this Section 4.2 shall be counted as one of the 20 quarters permitted
in the maximum Extended Interest Payment Period permitted under Section 4.1.

SECTION 4.3.    LIMITATION ON TRANSACTIONS.

     If (i) the Company shall exercise its right to defer payment of interest
as provided in Section 4.1; or (ii) there shall have occurred any Event of
Default, then (a) the Company shall not declare or pay any dividend or
distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any of its capital stock (other than (i) dividends or
distributions in common stock of the Company, or any declaration of a non-cash
dividend in connection with the implementation of a shareholders' rights plan,
or the issuance of stock under any such plan in the future, or the redemption
or repurchase of any such rights pursuant thereto, and (ii) purchases of common
stock of the Company related to the rights under any of the Company's benefit
plans for its directors, officers or employees); (b) the Company shall not make
any payment of principal, interest or premium, if any, on or repay, repurchase
or redeem any debt securities issued by the Company which rank pari passu with
or junior in interest to the Debentures; provided, however, that
notwithstanding the foregoing the Company may make payments pursuant to its
obligations under the Preferred Securities Guarantee; and (c) the Company shall
not redeem, purchase or acquire less than all of the outstanding Debentures or
any of the Preferred Securities.


                                  ARTICLE V.
                       PARTICULAR COVENANTS OF COMPANY

SECTION 5.1.    PAYMENT OF PRINCIPAL AND INTEREST.

     The Company shall duly and punctually pay or cause to be paid the
principal of and interest on the Debentures at the time and place and in the
manner provided herein.  Each such payment of the principal of 


   26

or interest on the Debentures shall relate only to the Debentures, shall not be
combined with any other payment of the principal of or interest on any other
obligation of the Company, and shall be clearly and unmistakably identified as
pertaining to the Debentures.

SECTION 5.2.    MAINTENANCE OF AGENCY.

     So long as any of the Debentures remain Outstanding, the Company shall
maintain an office or agency at such location or locations as may be designated
as provided in this Section 5.2, where (i) Debentures may be presented for
payment; (ii) Debentures may be presented as hereinabove authorized for
registration of transfer and exchange; and (iii) notices and demands to or upon
the Company in respect of the Debentures and this Indenture may be given or
served, such designation to continue with respect to such office or agency until
the Company shall, by written notice signed by its President or a Vice President
and delivered to the Trustee, designate some other office or agency for such
purposes or any of them.  If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, notices and demands may be made or served
at the Corporate Trust Office of the Trustee, and the Company hereby appoints
the Trustee as its agent to receive all such presentations, notices and 
demands.  The Company shall give the Trustee prompt written notice of any such
designation or rescission thereof.

SECTION 5.3.    PAYING AGENTS.

     (a)  The Trustee shall act as the Paying Agent.  If the Company shall
appoint one or more paying agents for the Debentures, other than the Trustee,
the Company shall cause each such paying agent to execute and deliver to the
Trustee an instrument in which such agent shall agree with the Trustee, subject
to the provisions of this Section 5.3:

            (i)   that it shall hold all sums held by it as
                  such agent for the payment of the principal of or
                  interest on the Debentures (whether such sums have been
                  paid to it by the Company or by any other obligor of
                  such Debentures) in trust for the benefit of the
                  Persons entitled thereto;

            (ii)  that it shall give the Trustee notice of
                  any failure by the Company (or by any other obligor of
                  such Debentures) to make any payment of the principal
                  of or interest on the Debentures when the same shall be
                  due and payable;

            (iii) that it shall, at any time during the
                  continuance of any failure referred to in the preceding
                  paragraph (a)(ii) above, upon the written request of
                  the Trustee, forthwith pay to the Trustee all sums so
                  held in trust by such Paying Agent; and

            (iv)  that it shall perform all other duties of
                  Paying Agent as set forth in this Indenture.


   27
     (b)  If the Company shall act as its own Paying Agent with respect to the
Debentures, it shall on or before each due date of the principal of or interest
on such Debentures, set aside, segregate and hold in trust for the benefit of
the Persons entitled thereto a sum sufficient to pay such principal or interest
so becoming due on Debentures until such sums shall be paid to such Persons or
otherwise disposed of as herein provided and shall promptly notify the Trustee
of such action, or any failure (by it or any other obligor on such Debentures) 
to take such action. Whenever the Company shall have one or more Paying Agents 
for the Debentures, it shall, prior to each due date of the principal of or 
interest on any Debentures, deposit with the Paying Agent a sum sufficient to 
pay the principal or interest so becoming due, such sum to be held in trust for
the benefit of the Persons entitled to such principal or interest, and (unless 
such Paying Agent is the Trustee) the Company shall promptly notify the Trustee
of this action or failure so to act.

     (c)  Notwithstanding anything in this Section 5.3 to the contrary, (i) the
agreement to hold sums in trust as provided in this Section 5.3 is subject to
the provisions of Section 13.3 and 13.4; and (ii) the Company may at any time,
for the purpose of obtaining the satisfaction and discharge of this Indenture
or for any other purpose, pay, or direct any Paying Agent to pay, to the
Trustee all sums held in trust by the Company or such Paying Agent, such sums
to be held by the Trustee upon the same terms and conditions as those upon
which such sums were held by the Company or such Paying Agent; and, upon such
payment by any Paying Agent to the Trustee, such Paying Agent shall be released
from all further liability with respect to such money.

SECTION 5.4.    APPOINTMENT TO FILL VACANCY IN OFFICE OF TRUSTEE.

     The Company, whenever necessary to avoid or fill a vacancy in the office
of Trustee, shall appoint, in the manner provided in Section 9.10, a Trustee,
so that there shall at all times be a Trustee hereunder.

SECTION 5.5.    COMPLIANCE WITH CONSOLIDATION PROVISIONS.

     The Company shall not, while any of the Debentures remain outstanding,
consolidate with, or merge into, or merge into itself, or sell or convey all or
substantially all of its property to any other company unless the provisions of
Article XII hereof are complied with.

SECTION 5.6.    LIMITATION ON TRANSACTIONS.

     If Debentures are issued to the Trust or a trustee of the Trust in
connection with the issuance of Trust Securities by the Trust and (i) there
shall have occurred any event that would constitute an Event of Default; (ii)
the Company shall be in default with respect to its payment of any obligations
under the Preferred Securities Guarantee relating to the Trust; or (iii) the
Company shall have given notice of its election to defer payments of interest
on such Debentures by extending the interest payment period as provided in this
Indenture and such period, or any extension thereof, shall be continuing, then
(a) the Company shall not declare or pay any dividends or distributions on, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
its capital stock (other than (i) dividends or distributions 




   28
in common stock of the Company, or any declaration of a non-cash dividend
in connection with the implementation of a shareholders' rights plan, or the
issuance of stock under any such plan in the future, or the redemption or
repurchase of any such rights pursuant thereto, and (ii) purchases of
common stock of the Company related to the rights under any of the Company's
benefit plans for its directors, officers or employees); (b) the Company shall
not make any payment of principal, interest or premium, if any, on or repay,
repurchase or redeem any debt securities issued by the Company which rank pari
passu with or junior in interest to the Debentures; provided, however, that the
Company may make payments pursuant to its obligations under the Preferred
Securities Guarantee; and (c) the Company shall not redeem, purchase or acquire
less than all of the outstanding Debentures or any of the Preferred Securities.

SECTION 5.7.    COVENANTS AS TO THE TRUST.

     For so long as the Trust Securities of the Trust remain outstanding, the
Company shall (i) maintain 100% direct or indirect ownership of the Common
Securities of the Trust; provided, however, that any permitted successor of the
Company under this Indenture may succeed to the Company's ownership of the
Common Securities; (ii) not voluntarily terminate, wind up or liquidate the
Trust, except upon prior approval of the Federal Reserve if then so required
under applicable capital guidelines or policies of the Federal Reserve and use
its reasonable efforts to cause the Trust (a) to remain a business trust,
except in connection with a distribution of Debentures, the redemption of all
of the Trust Securities of the Trust, or certain mergers, consolidations or
amalgamations, each as permitted by the Trust Agreement; and (b) to otherwise
continue not to be treated as an association taxable as a corporation or
partnership for United States federal income tax purposes; and (iii) use its
reasonable efforts to cause each holder of Trust Securities to be treated as
owning an individual beneficial interest in the Debentures.  In connection with
the distribution of the Debentures to the holders of the Preferred Securities
issued by the Trust upon a Dissolution Event, the Company shall use its best

                  REMEDIES OF TRUSTEE AND DEBENTUREHOLDERS
                             ON EVENT OF DEFAULT

SECTION 7.1.    EVENTS OF DEFAULT.

                 continuance of such default for a period of 30 days;
                 provided, however, that a valid extension of an
                 interest payment period by the Company in accordance
                 with the terms of this Indenture shall not constitute a
                 default in the payment of interest for this purpose;

            (ii) the Company defaults in the payment of the principal on the 
                 Debentures as and when the same shall become due and payable 
                 whether at maturity, upon redemption, by declaration or 
                 otherwise; provided, however, that a valid 



   31


                  extension of the maturity of such Debentures in accordance
                  with the terms of this Indenture shall not constitute a 
                  default in the payment of principal;

            (iii) the Company fails to observe or perform
                  any other of its covenants or agreements with respect
                  to the Debentures for a period of 90 days after the
                  date on which written notice of such failure, requiring
                  the same to be remedied and stating that such notice is
                  a "Notice of Default" hereunder, shall have been given
                  to the Company by the Trustee, by registered or
                  certified mail, or to the Company and the Trustee by
                  the holders of at least 25% in principal amount of the
                  Debentures at the time Outstanding;

           (iv)   the Company pursuant to or within the
                  meaning of any Bankruptcy Law (i) commences a voluntary
                  case; (ii) consents to the entry of an order for relief
                  against it in an involuntary case; (iii) consents to the
                  appointment of a Custodian of it or for all or

                  general assignment for the benefit of its creditors;

            (v)   a court of competent jurisdiction enters
                  an order under any Bankruptcy Law that (i) is for
                  relief against the Company in an involuntary case; (ii)
                  appoints a Custodian of the Company for all or
                  substantially all of its property; or iii) orders the
                  liquidation of the Company, and the order or decree
                  remains unstayed and in effect for 90 days; or

            (vi)  the Trust shall have voluntarily or
                  involuntarily dissolved, wound-up its business or
                  otherwise terminated its existence except in connection
                  with (i) the distribution of Debentures to holders of

     (b)  In each and every such case referred to in items (i) through (vi) of
Section 7.1(a), unless the principal of all the Debentures shall have already
become due and payable, either the Trustee or the holders of not less than 25%
in aggregate principal amount of the Debentures then Outstanding hereunder, by
notice in writing to the Company (and to the Trustee if given by such
Debentureholders) may declare the principal of all the Debentures to be due and
payable immediately, and upon any such declaration the same shall become and
shall be immediately due and payable, notwithstanding anything contained in this
Indenture or in the Debentures.


   32

     (c)  At any time after the principal of the Debentures shall have been so
declared due and payable, and before any judgment or decree for the payment of
the moneys due shall have been obtained or entered as hereinafter provided, the
holders of a majority in aggregate principal amount of the Debentures then
Outstanding hereunder, by written notice to the Company and the Trustee, may
rescind and annul such declaration and its consequences if: (i) the Company has
paid or deposited with the Trustee a sum sufficient to pay all matured
installments of interest upon all the Debentures and the principal of any and
all Debentures that shall have become due otherwise than by acceleration (with
interest upon such principal, and upon overdue installments of interest, at the
rate per annum expressed in the Debentures to the date of such payment or
deposit) and the amount payable to the Trustee under Section 9.7; and (ii)
any and all Events of Default under this Indenture, other than the nonpayment of
principal on Debentures that shall not have become due by their terms, shall
have been remedied or waived as provided in Section 7.6. No such rescission and
annulment shall extend to or shall affect any subsequent default or impair any
right consequent thereon.

     (d)  In case the Trustee shall have proceeded to enforce any right with
respect to Debentures under this Indenture and such proceedings shall have been
discontinued or abandoned because of such rescission or annulment or for any
other reason or shall have been determined adversely to the Trustee, then and
in every such case the Company and the Trustee shall be restored respectively
to their former positions and rights hereunder, and all rights, remedies and
powers of the Company and the Trustee shall continue as though no such
proceedings had been taken.

SECTION 7.2.    COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT
                BY TRUSTEE.

     (a)  The Company covenants that (1) in case it shall default in the
payment of any installment of interest on any of the Debentures, and such
default shall have continued for a period of 90 Business Days; or (2) in case
it shall default in the payment of the principal of any of the Debentures when
the same shall have become due and payable, whether upon maturity of the
Debentures or upon redemption or upon declaration or otherwise, then, upon
demand of the Trustee, the Company shall pay to the Trustee, for the benefit of
the holders of the Debentures, the whole amount that then shall have been
become due and payable on all such Debentures for principal or interest, or
both, as the case may be, with interest upon the overdue principal and (if the
Debentures are held by the Trust or a trustee of the Trust, without duplication
of any other amounts paid by the Trust or trustee in respect thereof) upon
overdue installments of interest at the rate per annum expressed in the
Debentures; and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, and the amount
payable to the Trustee under Section 9.7.

     (b)  If the Company shall fail to pay such amounts set forth in Section
7.2(a) forthwith upon such demand, the Trustee, in its own name and as trustee
of an express trust, shall be entitled and empowered to institute any action or
proceedings at law or in equity for the collection of the sums so due and
unpaid, and may prosecute any such 



   33


action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or other obligor upon the
Debentures and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or other obligor upon
the Debentures, wherever situated.

     (c)  In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, readjustment, arrangement, composition or judicial proceedings
affecting the Company or the creditors or property thereof, the Trustee shall
have power to intervene in such proceedings and take any action therein that
may be permitted by the court and shall (except as may be otherwise provided by
law) be entitled to file such proofs of claim and other papers and documents as
may be necessary or advisable in order to have the claims of the Trustee and of
the holders of the Debentures allowed for the entire amount due and payable by
the Company under this Indenture at the date of institution of such proceedings
and for any additional amount that may become due and payable by the Company
after such date, and to collect and receive any moneys or other property
payable or deliverable on any such claim, and to distribute the same after the
deduction of the amount payable to the Trustee under Section 9.7; and any
receiver, assignee or trustee in bankruptcy or reorganization is hereby
authorized by each of the holders of the Debentures to make such payments to
the Trustee, and, in the event that the Trustee shall consent to the making of
such payments directly to such Debentureholders, to pay to the Trustee any
amount due it under Section 9.7.

     (d)  All rights of action and of asserting claims under this Indenture, or
under any of the terms established with respect to Debentures, may be enforced
by the Trustee without the possession of any of such Debentures, or the
production thereof at any trial or other proceeding relative thereto, and any
such suit or proceeding instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment shall, after
provision for payment to the Trustee of any amounts due under Section 9.7, be
for the ratable benefit of the holders of the Debentures.  In case of an Event
of Default hereunder, the Trustee may in its discretion proceed to protect and
enforce the rights vested in it by this Indenture by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce any
of such rights, either at law or in equity or in bankruptcy or otherwise,
whether for the specific enforcement of any covenant or agreement contained in
this Indenture or in aid of the exercise of any power granted in this
Indenture, or to enforce any other legal or equitable right vested in the
Trustee by this Indenture or by law.  Nothing contained herein shall be deemed
to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Debentureholder any plan of reorganization, arrangement,
adjustment or composition affecting the Debentures or the rights of any holder
thereof or to authorize the Trustee to vote in respect of the claim of any
Debentureholder in any such proceeding.

SECTION 7.3.    APPLICATION OF MONEYS COLLECTED.

     Any moneys collected by the Trustee pursuant to this Article VII with
respect to the Debentures shall be applied in the following order, at the date
or dates fixed by the Trustee and, in case of the distribution of such moneys

             Debentures for principal and interest, in respect of which or for
             the benefit of which such money has been collected, ratably,
             without preference or priority of any kind, according to the
             amounts due and payable on such Debentures for principal and
             interest, respectively.


SECTION 7.4.    LIMITATION ON SUITS.

     (a)  Except as provided in section 15.13 hereof, no holder of any
Debenture shall have any right by virtue or by availing of any provision of
this Indenture to institute any suit, action or proceeding in equity or at law
upon or under or with respect to this Indenture or for the appointment of a
receiver or trustee, or for any other remedy hereunder, unless (i) such holder
previously shall have given to the Trustee written notice of an Event of
Default and of the continuance thereof with respect to the Debentures
specifying such Event of Default, as hereinbefore provided; (ii) the holders of
not less than 25% in aggregate principal amount of the Debentures then
Outstanding shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as trustee hereunder; (iii) such
holder or holders shall have offered to the Trustee such reasonable indemnity
as it may require against the costs, expenses and liabilities to be incurred
therein or thereby; and (iv) the Trustee for 60 days after its receipt of such
notice, request and offer of indemnity, shall have failed to institute any such
action, suit or proceeding; and (v) during such 60 day period, the holders of a
majority in principal amount of the Debentures do not give the Trustee a
direction inconsistent with the request.

     (b)  Notwithstanding anything contained herein to the contrary or
any other provisions of this Indenture, the right of any holder of the
Debentures to receive payment of the principal of and interest on the
Debentures, as therein provided, on or after the respective due dates expressed
in such Debenture (or in the case of redemption, on the redemption date), or to
institute suit for the enforcement of any such payment on or after such
respective dates or redemption date, shall not be impaired or affected without
the consent of such holder and by accepting a Debenture hereunder it is
expressly understood, intended and covenanted by the taker and holder of every
Debenture with every other such taker and holder and the Trustee, that no one
or more holders of Debentures shall have any right in any manner whatsoever by
virtue or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of the holders of any other of such 



   35

Debentures, or to obtain or seek to obtain priority over or preference to
any other such holder, or to enforce any right under this Indenture, except in
the manner herein provided and for the equal, ratable and common benefit of all
holders of Debentures.  For the protection and enforcement of the provisions of
this Section 7.4, each and every Debentureholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

SECTION 7.5.    RIGHTS AND REMEDIES CUMULATIVE; DELAY OR OMISSION
                NOT WAIVER.

     (a)  Except as otherwise provided in Section 2.9, all powers and remedies
given by this Article VII to the Trustee or to the Debentureholders shall, to
the extent permitted by law, be deemed cumulative and not exclusive of any
other powers and remedies available to the Trustee or the holders of the
Debentures, by judicial proceedings or otherwise, to enforce the performance or
observance of the covenants and agreements contained in this Indenture or
otherwise established with respect to such Debentures.

     (b)  No delay or omission of the Trustee or of any holder of any of the
Debentures to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or an acquiescence
therein; and, subject to the provisions of Section 7.4, every power and remedy
given by this Article VII or by law to the Trustee or the Debentureholders may
be exercised from time to time, and as often as shall be deemed expedient, by
the Trustee or by the Debentureholders.

SECTION 7.6.    CONTROL BY DEBENTUREHOLDERS.

     The holders of a majority in aggregate principal amount of the Debentures
at the time Outstanding, determined in accordance with Section 10.4, shall have
the right to direct the time, method and  place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power
conferred on the Trustee; provided, however, that such direction shall not be
in conflict with any rule of law or with this Indenture.  Subject to the
provisions of Section 9.1, the Trustee shall have the right to decline to
follow any such direction if the Trustee in good faith shall, by a Responsible
Officer or Officersof the Trustee, determine that the proceeding so
directed would involve the Trustee in personal liability.  The holders of a
majority in aggregate principal amount of the Debentures at the time Outstanding
affected thereby, determined in accordance with Section 10.4, may on behalf of
the holders of all of the Debentures waive any past default in the performance
of any of the covenants contained herein and its consequences, except (i) a
default in the payment of the principal of or interest on any of the Debentures
as and when the same shall become due by the terms of such Debentures otherwise
than by acceleration (unless such default has been cured and a sum sufficient to
pay all matured installments of interest and principal has been deposited with
the Trustee (in accordance with Section 7.1(c)); (ii) a default in the covenants
contained in Section 5.6; or (iii) in respect of a covenant or provision hereof
which cannot be modified or amended without the consent of the holder of each
Outstanding Debenture affected; provided, however, that if the 



   36

Debentures are held by the Trust or a trustee of the Trust, such waiver or
modification to such waiver shall not be effective until the holders of a
majority in liquidation preference of Trust Securities of the Trust shall have
consented to such waiver or modification to such waiver; provided further, that
if the consent of the holder of each Outstanding Debenture is required, such
waiver shall not be effective until each holder of the Trust Securities of the
Trust shall have consented to such waiver.  Upon any such waiver, the default
covered thereby shall be deemed to be cured for all purposes of this Indenture
and the Company, the Trustee and the holders of the Debentures shall be restored
to their former positions and rights hereunder, respectively; but no such waiver
shall extend to any subsequent or other default or impair any right consequent
thereon.

SECTION 7.7.    UNDERTAKING TO PAY COSTS.

     All parties to this Indenture agree, and each holder of any Debentures by
such holder's acceptance thereof shall be deemed to have agreed, that any court
may in its discretion require, in any suit for the enforcement of any right or
remedy under this Indenture, or in any suit against the Trustee for any action
taken or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may
in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section 7.7 shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Debentureholder, or group of
Debentureholders holding more than 10% in aggregate principal amount of the
Outstanding Debentures, or to any suit instituted by any Debentureholder for
the enforcement of the payment of the principal of or interest on the
Debentures, on or after the respective due dates expressed in such Debenture or
established pursuant to this Indenture.

the curing of all Events of Default that may have occurred, shall undertake to
perform with respect to the Debentures such duties and only such duties as are
specifically set forth in this Indenture, and no implied covenants shall be
read into this Indenture against the Trustee.  In case an Event of Default has
occurred that has not been cured or waived, the Trustee shall exercise such of

of care and skill in their exercise, as a prudent man would exercise or use
under the circumstances in the conduct of his own affairs.

     (b)  No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that:

     (1) prior to the occurrence of an Event of Default and after the curing or
waiving of all such Events of Default that may have occurred:

                  (i)  the duties and obligations of the Trustee shall with 
                       respect to the Debentures be determined solely by the 
                       express provisions of this Indenture, and the Trustee 
                       shall not be liable with respect to the Debentures 
                       except for the performance of such duties and 
                       obligations as are specifically set forth in this 
                       Indenture, and no implied covenants or obligations 
                       shall be read into this Indenture against the Trustee;
                       and

                  (ii) in the absence of bad faith on
                       the part of the Trustee, the Trustee may with
                       respect to the Debentures conclusively rely, as
                       to the truth of the statements and the
                       correctness of the opinions expressed therein,
                       upon any certificates or opinions furnished to
                       the Trustee and conforming to the requirements of
                       this Indenture; but in the case of any such
                       certificates or opinions that by any provision
                       hereof are specifically required to be furnished
                       to the Trustee, the Trustee shall be under a duty
                       to 

   38


                       examine the same to determine whether or not they 
                       conform to the requirements of this Indenture;

     (2) the Trustee shall not be liable for any error of judgment made in good
faith by a Responsible Officer or Responsible Officers of the Trustee,          
unless it shall be proved that the Trustee was negligent in ascertaining the
pertinent facts;

     (3) the Trustee shall not be liable with respect to any action taken
or omitted to be taken by it in good faith in accordance with the
direction of the holders of not less than a majority in principal amount of the
Debentures at the time Outstanding relating to the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred upon the Trustee under this Indenture
with respect to the Debentures; and

     (4) none of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there is reasonable ground for believing that the
repayment of such funds or liability is not reasonably assured to it under the
terms of this Indenture or adequate indemnity against such risk is not
reasonably assured to it.

SECTION 9.2.    NOTICE OF DEFAULTS.

     Within 90 days after actual knowledge by a Responsible Officer of the
Trustee of the occurrence of any default hereunder with respect to the
Debentures, the Trustee shall transmit by mail to all holders of the
Debentures, as their names and addresses appear in the Debenture Register,
notice of such default, unless such default shall have been cured or waived;
provided, however, that, except in the case of a default in the payment
of the principal or interest (including any Additional Payments) on any
Debenture, the Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee or a trust committee of
the directors and/or Responsible Officers of the Trustee determines in good
faith that the withholding of such notice is in the interests of the holders of
such Debentures; and provided, further, that in the case of any default of the
character specified in section 7.1(a)(iii), no such notice to holders of
Debentures need be sent until at least 30 days after the occurrence thereof. 
For the purposes of this Section 9.2, the term "default" means any event which
is, or after notice or lapse of time or both, would become, an Event of Default
with respect to the Debentures.

SECTION 9.3.    CERTAIN RIGHTS OF TRUSTEE.

     Except as otherwise provided in Section 9.1:

     (a)  The Trustee may rely and shall be protected in acting or refraining
from acting upon any resolution, certificate, statement, instrument, opinion,
report, notice, request, consent, order, approval, 



   39

bond, security or other paper or document believed by it to be genuine and to
have been signed or presented by the proper party or parties;

     (b)  Any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by a Board Resolution or an instrument
signed in the name of the Company by the President or any Vice President and by
the Secretary or an Assistant Secretary or the Treasurer or an Assistant
Treasurer thereof (unless other evidence in respect thereof is specifically
prescribed herein);

     (c)  The Trustee shall not be deemed to have knowledge of a default or an
Event of Default, other than an Event of Default specified in Section 7.1(a)(i)
or (ii), unless and until it receives written notification of such Event of
Default from the Company or by holders of at least 25% of the aggregate
principal amount of the Debentures at the time Outstanding;

     (d)  The Trustee may consult with counsel and the written advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken or suffered or omitted hereunder in
good faith and in reliance thereon;

     (e)  The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
direction of any of the Debentureholders, pursuant to the provisions of this
Indenture, unless such Debentureholders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
that may be incurred therein or thereby; nothing contained herein shall,
however, relieve the Trustee of the obligation, upon the occurrence of an Event
of Default (that has not been cured or waived) to exercise with respect to the
Debentures such of the rights and powers vested in it by this Indenture, and to
use the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his
own affairs;

     (f)  The Trustee shall not be liable for any action taken or omitted to be
taken by it in good faith and believed by it to be authorized or within the
discretion or rights or powers conferred upon it by this Indenture;

     (g)  The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, security, or
other papers or documents, unless requested in writing so to do by the holders
of not less than a majority in principal amount of the Outstanding Debentures
(determined as provided in Section 10.4); provided, however, that if the
payment within a reasonable time to the Trustee of the costs, expenses or
liabilities likely to be incurred by it in the making of such investigation is,
in the opinion of the Trustee, not reasonably assured to the Trustee by the
security afforded to it by the terms of this Indenture, the Trustee may require
reasonable indemnity against such costs, expenses or liabilities as a condition
to so proceeding.  The reasonable expense of every such examination shall be
paid by the Company or, if paid by the Trustee, shall be repaid by the Company
upon demand; and


   40


     (h)  The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder.

SECTION 9.4.    TRUSTEE NOT RESPONSIBLE FOR RECITALS, ETC.

     (a)  The Recitals contained herein and in the Debentures shall be taken as
the statements of the Company, and the Trustee assumes no responsibility for
the correctness of the same.

     (b)  The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Debentures.

     (c)  The Trustee shall not be accountable for the use or application by
the Company of any of the Debentures or of the proceeds of such Debentures, or
for the use or application of any moneys paid over by the Trustee in accordance
with any provision of this Indenture, or for the use or application of any
moneys received by any paying agent other than the Trustee.

SECTION 9.5.    MAY HOLD DEBENTURES.

     The Trustee or any Paying Agent or Debenture Registrar for the Debentures,
in its individual or any other capacity, may become the owner or pledgee of
Debentures with the same rights it would have if it were not Trustee, Paying
Agent or Debenture Registrar.

SECTION 9.6.    MONEYS HELD IN TRUST.

     Subject to the provisions of Section 13.5, all moneys received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from
other funds except to the extent required by law.  The Trustee shall be under
no liability for interest on any moneys received by it hereunder except such as
it may agree with the Company to pay thereon.

SECTION 9.7.    COMPENSATION AND REIMBURSEMENT.

     (a)  The Company covenants and agrees to pay to the Trustee, and the
Trustee shall be entitled to, such reasonable compensation (which shall not be
limited by any provision of law in regard to the compensation of a trustee of
an express trust), as the Company and the Trustee may from time to time agree
in writing, for all services rendered by it in the execution of the trusts
hereby created and in the exercise and performance of any of the powers and
duties hereunder of the Trustee, and, except as otherwise expressly provided
herein, the Company shall pay or reimburse the Trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by the Trustee
in accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and
of all Persons not regularly in its employ) except any such expense,
disbursement or advance as may arise from its negligence or bad faith.  The
Company also covenants to indemnify the Trustee (and its officers, agents,
directors and 



   41

employees) for, and to hold it harmless against, any loss, liability or
expense incurred without negligence or bad faith on the part of the Trustee and
arising out of or in connection with the acceptance or administration of this
trust, including the costs and expenses of defending itself against any claim of
liability in the premises.

     (b)  The obligations of the Company under this Section 9.7 to compensate
and indemnify the Trustee and to pay or reimburse the Trustee for expenses,
disbursements and advances shall constitute additional indebtedness hereunder.
Such additional indebtedness shall be secured by a lien prior to that of the
Debentures upon all property and funds held or collected by the Trustee as
such, except funds held in trust for the benefit of the holders of particular
Debentures.

SECTION 9.8.    RELIANCE ON OFFICERS' CERTIFICATE.

     Except as otherwise provided in Section 9.1, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking
or suffering or omitting to take any action hereunder, such matter (unless
other evidence in respect thereof be herein specifically prescribed) may, in
the absence of negligence or bad faith on the part of the Trustee, be deemed to
be conclusively proved and established by an Officers' Certificate delivered to
the Trustee and such certificate, in the absence of negligence or bad faith on
the part of the Trustee, shall be full warrant to the Trustee for any action
taken, suffered or omitted to be taken by it under the provisions of this
Indenture upon the faith thereof.

SECTION 9.9.    DISQUALIFICATION:  CONFLICTING INTERESTS.

     If the Trustee has or shall acquire any "conflicting interest" within the
meaning of Section 310(b) of the Trust Indenture Act, the Trustee and the
Company shall in all respects comply with the provisions of Section 310(b) of
the Trust Indenture Act.

SECTION 9.10.   CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

     There shall at all times be a Trustee with respect to the Debentures
issued hereunder which shall at all times be a corporation organized and doing
business under the laws of the United States of America or any State or
Territory thereof or of the District of Columbia, or a corporation or other
Person permitted to act as trustee by the Commission, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least $50,000,000, and subject to supervision or examination by federal,
state, territorial, or District of Columbia authority.  If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 9.10, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.  The Company may not, nor
may any Person directly or indirectly controlling, controlled by, or under
common control with the Company, serve as Trustee.  In case at any time the
Trustee shall cease to be eligible in accordance with the provisions of 


   42

this Section 9.10, the Trustee shall resign immediately in the manner and
with the effect specified in Section 9.11.

SECTION 9.11.   RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

     (a)  The Trustee or any successor hereafter appointed, may at any time
resign by giving written notice thereof to the Company and by transmitting
notice of resignation by mail, first class postage prepaid, to the
Debentureholders, as their names and addresses appear upon the Debenture
Register.  Upon receiving such notice of resignation, the Company shall
promptly appoint a successor trustee with respect to Debentures by written
instrument, in duplicate, executed by order of the Board of Directors, one copy
of which instrument shall be delivered to the resigning Trustee and one copy to
the successor trustee. If no successor trustee shall have been so appointed and
have accepted appointment within 30 days after the mailing of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee with respect to
Debentures, or any Debentureholder who has been a bona fide holder of a
Debenture or Debentures for at least six months may, subject to the provisions
of Section 9.11, on behalf of himself and all others similarly situated,
petition any such court for the appointment of a successor trustee.  Such court
may thereupon after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee.

     (b)  In case at any time any one of the following shall occur

             (i)   the Trustee shall fail to comply with
                   the provisions of Section 9.9 after written request
                   therefor by the Company or by any Debentureholder who
                   has been a bona fide holder of a Debenture or
                   Debentures for at least six months; or

             (ii)  the Trustee shall cease to be eligible
                   in accordance with the provisions of Section 9.10 and
                   shall fail to resign after written request therefor by
                   the Company or by any such Debentureholder; or

             (iii) the Trustee shall become incapable of
                   acting, or shall be adjudged a bankrupt or insolvent,
                   or commence a voluntary bankruptcy proceeding, or a
                   receiver of the Trustee or of its property shall be
                   appointed or consented to, or any public officer shall
                   take charge or control of the Trustee or of its
                   property or affairs for the purpose of rehabilitation,
                   conservation or liquidation, then, in any such case,
                   the Company may remove the Trustee with respect to all
                   Debentures and appoint a successor trustee by written
                   instrument, in duplicate, executed by order of the
                   Board of Directors, one copy of which instrument shall
                   be delivered to the Trustee so removed and one copy to
                   the successor trustee, or, subject to the 


   43

                   provisions of Section 9.9, unless the Trustee's duty to
                   resign is stayed as provided herein, any Debentureholder who
                   has been a bona fide holder of a Debenture or Debentures for
                   at least six months may, on behalf of that holder and all
                   others similarly situated, petition any court of competent
                   jurisdiction for the removal of the Trustee and the
                   appointment of a successor trustee. Such court may thereupon
                   after such notice, if any, as it may deem proper and
                   prescribe, remove the Trustee and appoint a successor
                   trustee.

     (c)  The holders of a majority in aggregate principal amount of the
Debentures at the time Outstanding may at any time remove the Trustee by so
notifying the Trustee and the Company and may appoint a successor Trustee with
the consent of the Company.

     (d)  Any resignation or removal of the Trustee and appointment of a
successor trustee with respect to the Debentures pursuant to any of the
provisions of this Section 9.11 shall become effective upon acceptance of
appointment by the successor trustee as provided in Section 9.12.

     (e)  Any successor trustee appointed pursuant to this Section 9.11
may be appointed with respect to the Debentures, and at any time there shall be
only one Trustee with respect to the Debentures.

SECTION 9.12.   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

     (a)  In case of the appointment hereunder of a successor trustee with
respect to the Debentures, every successor trustee so appointed shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such
successor trustee all the rights, powers, and trusts of the retiring Trustee
and shall duly assign, transfer and deliver to such successor trustee all
property and money held by such retiring Trustee hereunder.

     (b)  Upon request of any successor trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor trustee all such rights, powers and trusts referred to in
Section 9.12(a).

     (c)  No successor trustee shall accept its appointment unless at the time
of such acceptance such successor trustee shall be qualified and eligible under
this Article IX.

     (d)  Upon acceptance of appointment by a successor trustee as provided in
this Section 9.12, the Company shall transmit notice of the succession of such
trustee hereunder by mail, first class postage 


   44

prepaid, to the Debentureholders, as their names and addresses appear upon the
Debenture Register.  If the Company fails to transmit such notice within ten
days after acceptance of appointment by the successor trustee, the successor
trustee shall cause such notice to be transmitted at the expense of the Company.

SECTION 9.13.   MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
                BUSINESS.

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder, provided that such corporation shall be
qualified under the provisions of Section 9.9 and eligible under the provisions
of Section 9.10, without the execution or filing of any paper or any further
act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding.  In case any Debentures shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion
or consolidation to such authenticating Trustee may adopt such authentication
and deliver the Debentures so authenticated with the same effect as if such
successor Trustee had itself authenticated such Debentures.

SECTION 9.14.   PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE
                COMPANY.

     The Trustee shall comply with Section 311(a) of the Trust Indenture Act,
excluding any creditor relationship described in Section 311(b) of the Trust
Indenture Act.  A Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent included therein.


                                  ARTICLE X.
                         CONCERNING DEBENTUREHOLDERS

SECTION 10.1.   EVIDENCE OF ACTION BY HOLDERS.

     (a)  Whenever in this Indenture it is provided that the holders of a
majority or specified percentage in aggregate principal amount of the
Debentures may take any action (including the making of any demand or request,
the giving of any notice, consent or waiver or the taking of any other action),
the fact that at the time of taking any such action the holders of such
majority or specified percentage have joined therein may be evidenced by any
instrument or any number of instruments of similar tenor executed by such
holders of Debentures in Person or by agent or proxy appointed in writing.

     (b)  If the Company shall solicit from the Debentureholders any request,
demand, authorization, direction, notice, consent, waiver or other action, the
Company may, at its option, as evidenced by an Officers' Certificate, fix in
advance a record date for the determination of Debentureholders entitled to
give such request, demand, authorization, direction, notice, consent, waiver or
other action, but the Company shall have no obligation to do so. If such a



   45

record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other action may be given before or after the record date,
but only the Debentureholders of record at the close of business on the record
date shall be deemed to be Debentureholders for the purposes of determining
whether Debentureholders of the requisite proportion of Outstanding Debentures
have authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other action, and for that purpose the
Outstanding Debentures shall be computed as of the record date; provided,
however, that no such authorization, agreement or consent by such
Debentureholders on the record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than
six months after the record date.

SECTION 10.2.   PROOF OF EXECUTION BY DEBENTUREHOLDERS.

     Subject to the provisions of Section 9.1, proof of the execution of any
instrument by a Debentureholder (such proof shall not require notarization) or
his agent or proxy and proof of the holding by any Person of any of the
Debentures shall be sufficient if made in the following manner:

     (a)  The fact and date of the execution by any such Person of any
instrument may be proved in any reasonable manner acceptable to the Trustee.

     (b)  The ownership of Debentures shall be proved by the Debenture Register
of such Debentures or by a certificate of the Debenture Registrar thereof.

     (c)  The Trustee may require such additional proof of any matter referred
to in this Section 10.2 as it shall deem necessary.

SECTION 10.3.   WHO MAY BE DEEMED OWNERS.

     Prior to the due presentment for registration of transfer of any
Debenture, the Company, the Trustee, any Paying Agent, any Authenticating Agent
and any Debenture Registrar may deem and treat the Person in whose name such
Debenture shall be registered upon the books of the Company as the absolute
owner of such Debenture (whether or not such Debenture shall be overdue and
notwithstanding any notice of ownership or writing thereon made by anyone other
than the Debenture Registrar) for the purpose of receiving payment of or on
account of the principal of and interest on such Debenture (subject to Section
2.3) and for all other purposes; and neither the Company nor the Trustee nor
any Paying Agent nor any Authenticating Agent nor any Debenture Registrar shall
be affected by any notice to the contrary.

SECTION 10.4.   CERTAIN DEBENTURES OWNED BY COMPANY DISREGARDED.

     In determining whether the holders of the requisite aggregate principal
amount of Debentures have concurred in any direction, consent or waiver under
this Indenture, the Debentures that are owned by the Company or any other
obligor on the Debentures or by any Person directly or indirectly controlling
or controlled by or under common control with the Company or any other obligor
on the Debentures shall be disregarded and deemed not to be Outstanding for the
purpose of any 


   46

such determination, except that for the purpose of determining whether the
Trustee shall be protected in relying on any such direction, consent or waiver,
only Debentures that the Trustee actually knows are so owned shall be so
disregarded.  The Debentures so owned that have been pledged in good faith may
be regarded as Outstanding for the purposes of this Section 10.4, if the
pledgee shall establish to the satisfaction of the Trustee the pledgee's right
so to act with respect to such Debentures and that the pledgee is not a Person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company or any such other obligor. In case of a dispute
as to such right, any decision by the Trustee taken upon the advice of counsel
shall be full protection to the Trustee.

SECTION 10.5.   ACTIONS BINDING ON FUTURE DEBENTUREHOLDERS.

     At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 10.1, of the taking of any action by the holders
of the majority or percentage in aggregate principal amount of the Debentures
specified in this Indenture in connection with such action, any holder of a
Debenture that is shown by the evidence to be included in the Debentures the
holders of which have consented to such action may, by filing written notice
with the Trustee, and upon proof of holding as provided in Section 10.2, revoke
such action so far as concerns such Debenture. Except as aforesaid any such
action taken by the holder of any Debenture shall be conclusive and binding
upon such holder and upon all future holders and owners of such Debenture, and
of any Debenture issued in exchange therefor, on registration of transfer
thereof or in place thereof, irrespective of whether or not any notation in
regard thereto is made upon such Debenture.  Any action taken by the holders of
the majority or percentage in aggregate principal amount of the Debentures
specified in this Indenture in connection with such action shall be
conclusively binding upon the Company, the Trustee and the holders of all the
Debentures.


                                 ARTICLE XI.
                           SUPPLEMENTAL INDENTURES

SECTION 11.1.   SUPPLEMENTAL INDENTURES WITHOUT THE CONSENT OF
                DEBENTUREHOLDERS.

     In addition to any supplemental indenture otherwise authorized by this
Indenture, the Company and the Trustee may from time to time and at any time
enter into an indenture or indentures supplemental hereto (which shall conform
to the provisions of the Trust Indenture Act as then in effect), without the
consent of the Debentureholders, for one or more of the following purposes:

     (a)  to cure any ambiguity, defect, or inconsistency herein or in the
Debentures;

     (b)  to comply with Article X;

     (c)  to provide for uncertificated Debentures in addition to or in place
of certificated Debentures;


   47


     (d)  to add to the covenants of the Company for the benefit of the holders
of all or any of the Debentures or to surrender any right or power herein
conferred upon the Company;

     (e)  to add to, delete from, or revise the conditions, limitations, and
restrictions on the authorized amount, terms, or purposes of issue,
authentication, and delivery of Debentures, as herein set forth;

     (f)  to make any change that does not adversely affect the rights of any
Debentureholder in any material respect;

     (g)  to provide for the issuance of and establish the form and terms and
conditions of the Debentures, to establish the form of any certifications
required to be furnished pursuant to the terms of this Indenture or of the
Debentures, or to add to the rights of the holders of the Debentures;

     (h)  qualify or maintain the qualification of this Indenture under the
Trust Indenture Act; or

     (i)  to evidence a consolidation or merger involving the Company as
permitted under Section 21.1.

The Trustee is hereby authorized to join with the Company in the execution of
any such supplemental indenture, and to make any further appropriate agreements
and stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into any such supplemental indenture that affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.
Any supplemental indenture authorized by the provisions of this Section 11.1
may be executed by the Company and the Trustee without the consent of the
holders of any of the Debentures at the time Outstanding, notwithstanding any
of the provisions of Section 11.2.

SECTION 11.2.   SUPPLEMENTAL INDENTURES WITH CONSENT OF
                DEBENTUREHOLDERS.

     With the consent (evidenced as provided in Section 10.1) of the holders of
not less than a majority in aggregate principal amount of the Debentures at the
time Outstanding, the Company, when authorized by Board Resolutions, and the
Trustee may from time to time and at any time enter into an indenture or
indentures supplemental hereto (which shall conform to the provisions of the
Trust Indenture Act as then in effect) for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of this
Indenture or of any supplemental indenture or of modifying in any manner not
covered by Section 11.1 the rights of the holders of the Debentures under this
Indenture; provided, however, that no such supplemental indenture shall without
the consent of the holders of each Debenture then Outstanding and affected
thereby, (i) extend the fixed maturity of any Debentures, reduce the principal
amount thereof, or reduce the rate or extend the time of payment of interest
thereon, without the consent of the holder of each Debenture so affected; or
(ii) reduce the aforesaid percentage of Debentures, the holders of which are
required to consent to any such supplemental indenture; provided further, that
if the Debentures are held by the Trust or a trustee of the Trust, such
supplemental 



   48

indenture shall not be effective until the holders of a majority in
liquidation preference of Trust Securities of the Trust shall have consented to
such supplemental indenture; provided further, that if the consent of the
holder of each Outstanding Debenture is required, such supplemental indenture
shall not be effective until each holder of the Trust Securities of the Trust
shall have consented to such supplemental indenture.  It shall not be necessary
for the consent of the Debentureholders affected thereby under this Section
11.2 to approve the particular form of any proposed supplemental indenture, but
it shall be sufficient if such consent shall approve the substance thereof.

SECTION 11.3.   EFFECT OF SUPPLEMENTAL INDENTURES.

     Upon the execution of any supplemental indenture pursuant to the
provisions of this Article XI, this Indenture shall be and be deemed to be
modified and amended in accordance therewith and the respective rights,
limitations of rights, obligations, duties and immunities under this Indenture
of the Trustee, the Company and the holders of Debentures shall thereafter be
determined, exercised and enforced hereunder subject in all respects to such
modifications and amendments, and all the terms and conditions of any such
supplemental indenture shall be and be deemed to be part of the terms and
conditions of this Indenture for any and all purposes.

SECTION 11.4.   DEBENTURES AFFECTED BY SUPPLEMENTAL INDENTURES.

     Debentures affected by a supplemental indenture, authenticated and
delivered after the execution of such supplemental indenture pursuant to the
provisions of this Article XI, may bear a notation in form approved by the
Company, provided such form meets the requirements of any exchange upon which
the Debentures may be listed, as to any matter provided for in such
supplemental indenture.  If the Company shall so determine, new Debentures so
modified as to conform, in the opinion of the Board of Directors of the
Company, to any modification of this Indenture contained in any such
supplemental indenture may be prepared by the Company, authenticated by the
Trustee and delivered in exchange for the Debentures then Outstanding.

SECTION 11.5.   EXECUTION OF SUPPLEMENTAL INDENTURES.

     (a)  Upon the request of the Company, accompanied by its Board Resolutions
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of Debentureholders required
to consent thereto as aforesaid, the Trustee shall join with the Company in the
execution of such supplemental indenture unless such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion but shall not be
obligated to enter into such supplemental indenture.  The Trustee, subject to
the provisions of Sections 9.1, may receive an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant to this Article XI
is authorized or permitted by, and conforms to, the terms of this Article XI
and that it is proper for the Trustee under the provisions of this Article XI
to join in the execution thereof.


   49


     (b)  Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section 11.5, the
Trustee shall transmit by mail, first class postage prepaid, a notice, setting
forth in general terms the substance of such supplemental indenture, to the
Debentureholders as their names and addresses appear upon the Debenture
Register. Any failure of the Trustee to mail such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any
such supplemental indenture.

the case may be, or its successor or successors shall be a party or parties, or
shall prevent any sale, conveyance, transfer or other disposition of the
property of the Company, as the case may be, or its successor or successors as
an entirety, or substantially as an entirety, to any other corporation (whether
or not affiliated with the Company, as the case may be, or its successor or
successors) authorized to acquire and operate the same; provided, however, that
the Company hereby covenants and agrees that, (i) upon any such consolidation,
merger, sale, conveyance, transfer or other disposition, the due and punctual
payment, in the case of the Company, of the principal of and interest on all of
the Debentures, according to their tenor and the due and punctual performance
and observance of all the covenants and conditions of this Indenture to be kept
or performed by the Company as the case may be, shall be expressly assumed, by
supplemental indenture (which shall conform to the provisions of the Trust
Indenture Act, as then in effect) satisfactory in form to the Trustee executed
and delivered to the Trustee by the entity formed by such consolidation, or
into which the Company, as the case may be, shall have been merged, or by the
entity which shall have acquired such property; (ii)  in case the Company
consolidates with or merges into another Person or conveys or transfers its
properties and assets substantially as an entirety to any Person, the successor
Person is organized under the laws of the United States or any state or the
District of Columbia; and (iii) immediately after giving effect thereto, no
Event of Default, and no event which, after notice or lapse of time or both,
would become an Event of Default, shall have occurred and be continuing.

     (a)  In case of any such consolidation, merger, sale, conveyance, transfer
or other disposition and upon the assumption by the successor corporation, by
supplemental indenture, executed and delivered to the Trustee and satisfactory
in form to the Trustee, of the due and punctual payment of the principal of and
interest on all of the Debentures Outstanding and the due and punctual
performance of all of the covenants and conditions of this Indenture to be
performed by the 



   50

Company such successor corporation shall succeed to and be substituted for
the Company, with the same effect as if it had been named as the Company
herein, and thereupon the predecessor corporation shall be relieved of all
obligations and covenants under this Indenture and the Debentures.

     (b)  In case of any such consolidation, merger, sale, conveyance, transfer
or other disposition such changes in phraseology and form (but not in
substance) may be made in the Debentures thereafter to be issued as may be
appropriate.

     (c)  Nothing contained in this Indenture or in any of the Debentures shall
prevent the Company from merging into itself or acquiring by purchase or
otherwise all or any part of the property of any other Person (whether or not
affiliated with the Company).

     The Trustee, subject to the provisions of Section 9.1, may receive an
Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale, conveyance, transfer or other disposition, and any such assumption,
comply with the provisions of this Article XII.

been replaced or paid as provided in Section 2.9) and Debentures for whose
payment money or Governmental Obligations have theretofore been deposited in
trust or segregated and held in trust by the Company (and thereupon repaid to
the Company or discharged from such trust, as provided in Section 13.5); or (b)

shall have become due and payable, or are by their terms to become due and
payable within one year or are to be called for redemption within one year
under arrangements satisfactory to the Trustee for the giving of notice of
redemption, and the Company shall deposit or cause to be deposited with the
Trustee as trust funds the entire amount in moneys or Governmental Obligations
sufficient, or a combination thereof, sufficient in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, to pay at maturity or upon
redemption all Debentures not theretofore delivered to the Trustee for
cancellation, including principal and interest due or to become due to such
date of maturity or date fixed for redemption, as the case may be, and if the
Company shall also pay or cause to be paid all other sums payable hereunder by
the Company; then this Indenture shall thereupon cease to be of further effect
except for the provisions of Sections 2.3, 2.7, 2.9, 5.1, 5.2, 5.3 and 9.10,
that shall survive until the date of maturity or redemption date, as the case
may be, and Sections 9.6 and 13.5, that shall survive to such date and
thereafter, and the 


   51

Trustee, on demand of the Company and at the cost and expense of the Company,
shall execute proper instruments acknowledging satisfaction of and discharging
this Indenture.

Trustee as trust funds moneys or an amount of Governmental Obligations
sufficient in the opinion of a nationally recognized certified public
accounting firm to pay at maturity or upon redemption all Debentures not
theretofore delivered to the Trustee for cancellation, including principal and
interest due or to become due to such date of maturity or date fixed for
redemption, as the case may be, and if the Company shall also pay or cause to
be paid all other sums payable hereunder by the Company, then after the date
such moneys or Governmental Obligations, as the case may be, are deposited with
the Trustee, the obligations of the Company under this Indenture shall cease to
be of further effect except for the provisions of Sections 2.3, 2.7, 2.9, 5.1,
5.2, 5.3, 9.6, 9.10 and 13.5 hereof that shall survive until such Debentures
shall mature and be paid.  Thereafter, Sections 9.6 and 13.5 shall survive.


SECTION 13.3.   DEPOSITED MONEYS TO BE HELD IN TRUST.

     All monies or Governmental Obligations deposited with the Trustee pursuant
to Sections 13.1 or 13.2 shall be held in trust and shall be available for
payment as due, either directly or through any Paying Agent (including the
Company acting as its own Paying Agent), to the holders of the Debentures for
the payment or redemption of which such moneys or Governmental Obligations have
been deposited with the Trustee.

SECTION 13.4.   PAYMENT OF MONIES HELD BY PAYING AGENTS.

     In connection with the satisfaction and discharge of this Indenture, all

Trustee and thereupon such Paying Agent shall be released from all further
liability with respect to such moneys or Governmental Obligations.

SECTION 13.5.   REPAYMENT TO COMPANY.

     Any monies or Governmental Obligations deposited with any Paying Agent or
the Trustee, or then held by the Company in trust, for payment of principal of
or interest on the Debentures that are not applied but remain unclaimed by the
holders of such Debentures for at least two years after the date upon which the
principal of or interest on such Debentures shall have respectively become due
and payable, shall be repaid to the Company, as the case may be, on May 31 of
each year or (if then held by the Company) shall be discharged from such trust;
and thereupon the Paying Agent and the Trustee shall be released from all
further liability with respect to such moneys or Governmental Obligations, and
the holder of any of the Debentures entitled to 


   52

receive such payment shall thereafter, as an unsecured general creditor,
look only to the Company for the payment thereof.

Indenture, or of the Debentures, or for any claim based thereon or otherwise in
respect thereof, shall be had against any incorporator, stockholder, officer or
director, past, present or future as such, of the Company or of any predecessor
or successor corporation, either directly or through the Company or any such
predecessor or successor corporation, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment or penalty or
otherwise; it being expressly understood that this Indenture and the
obligations issued hereunder are solely corporate obligations, and that no such
personal liability whatever shall attach to, or is or shall be incurred by, the
incorporators, stockholders, officers or directors as such, of the Company or
of any predecessor or successor corporation, or any of them, because of the
creation of the indebtedness hereby authorized, or under or by reason of the
obligations, covenants or agreements contained in this Indenture or in any of
the Debentures or implied therefrom; and that any and all such personal
liability of every name and nature, either at common law or in equity or by
constitution or statute, and any and all such rights and claims against, every
such incorporator, stockholder, officer or director as such, because of the
creation of the indebtedness hereby authorized, or under or by reason of the
obligations, covenants or agreements contained in this Indenture or in any of
the Debentures or implied therefrom, are hereby expressly waived and released
as a condition of, and as a consideration for, the execution of this Indenture
and the issuance of such Debentures.

     It is intended that the Debentures shall be treated as indebtedness and
not as equity for federal income tax purposes.  The provisions of this
Indenture shall be interpreted to further this intention.

     (b)  Each certificate or opinion of the Company provided for in this

     If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with the duties imposed by Sections 310 to 317,
inclusive, of the Trust Indenture Act, such imposed duties shall control.



SECTION 15.10.  COUNTERPARTS.

     This Indenture may be executed in any number of counterparts, each of
which shall be an original, but such counterparts shall together constitute but
one and the same instrument.

SECTION 15.11.  SEPARABILITY.

     In case any one or more of the provisions contained in this Indenture or
in the Debentures shall for any reason be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Indenture or of the Debentures,
but this Indenture and the Debentures shall be construed as if such invalid or
illegal or unenforceable provision had never been contained herein or therein.

SECTION 15.12.  ASSIGNMENT.

     The Company shall have the right at all times to assign any of its
respective rights or obligations under this Indenture to a direct or indirect
wholly owned Subsidiary of the Company, provided that, in the event of any such
assignment, the Company shall remain liable for all such obligations.  Subject
to the foregoing, this Indenture is binding upon and inures to the benefit of
the parties thereto and their respective successors and assigns.  This
Indenture may not otherwise be assigned by the parties thereto.

SECTION 15.13.  ACKNOWLEDGMENT OF RIGHTS; RIGHT OF SETOFF.

     (a)  The Company acknowledges that, with respect to any Debentures held by
the Trust or a trustee of the Trust, if the Property Trustee fails to enforce   
its rights under this Indenture as the holder of the Debentures held as the
assets of the Trust, any holder of Preferred Securities may institute legal
proceedings directly against the Company 


   55

to enforce such Property Trustee's rights under this Indenture without first
instituting any legal proceedings against such Property Trustee or any other
person or entity. Notwithstanding the foregoing, and notwithstanding the
provisions of Section 7.4(a) hereof, if an Event of Default has occurred and is
continuing and such event is attributable to the failure of the Company to pay
interest or principal on the Debentures on the date such interest or principal
is otherwise payable (or in the case of redemption, on the redemption date),
the Company acknowledges that a holder of Preferred Securities may directly
institute a proceeding for enforcement of payment to such holder of the
principal of or interest on the Debentures having a principal amount equal to
the aggregate liquidation amount of the Preferred Securities of such holder on
or after the respective due date specified in the Debentures.

     (b)  Notwithstanding anything to the contrary contained in this Indenture,
the Company shall have the right of setoff any payment it is otherwise required
to make hereunder in respect of any Trust Securities to the extent that the
Company has previously made, or is concurrently making, a payment to the holder
of such Trust Securities under the Guarantee or in connection with a proceeding
for enforcement of payment of the principal of or interest on the Debentures
directly brought by holders of any Trust Securities.

                                ARTICLE XVI.
                         SUBORDINATION OF DEBENTURES

SECTION 16.1.   AGREEMENT TO SUBORDINATE.

     The Company covenants and agrees, and each holder of Debentures issued
hereunder by such holder's acceptance thereof likewise covenants and agrees,
that all Debentures shall be issued subject to the provisions of this Article
XVI; and each holder of a Debenture, whether upon original issue or upon
transfer or assignment thereof, accepts and agrees to be bound by such
provisions.  The payment by the Company of the principal of and interest on all
Debentures issued hereunder shall, to the extent and in the manner hereinafter
set forth, be subordinated and junior in right of payment to the prior payment
in full of all Senior Debt, Subordinated Debt and Additional Senior Obligations
(collectively, "Senior Indebtedness") to the extent provided herein, whether
outstanding at the date of this Indenture or thereafter incurred.  No provision
of this Article XVI shall prevent the occurrence of any default or Event of
Default hereunder.

SECTION 16.2.   DEFAULT ON SENIOR DEBT, SUBORDINATED DEBT OR
                ADDITIONAL SENIOR OBLIGATIONS.

     In the event and during the continuation of any default by the Company in
the payment of principal, premium, interest or any other payment due on any
Senior Indebtedness of the Company, or in the event that the maturity of any
Senior Indebtedness of the Company has been accelerated because of a default,
then, in either case, no payment shall be made by the Company with respect to
the principal (including redemption payments) of or interest on the Debentures.
In the event that, notwithstanding the foregoing, any payment shall be received
by the Trustee when such payment is prohibited by the preceding sentence of
this Section 16.2, such payment shall be held in trust for the 


   56

benefit of, and shall be paid over or delivered to, the holders of Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing within 90 days of
such payment of the amounts then due and owing on the Senior Indebtedness and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of Senior Indebtedness.

SECTION 16.3.   LIQUIDATION; DISSOLUTION; BANKRUPTCY.

     (a)  Upon any payment by the Company or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding-up or liquidation or reorganization
of the Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due upon all Senior Indebtedness
of the Company shall first be paid in full, or payment thereof provided for in
money in accordance with its terms, before any payment is made by the Company
on account of the principal or interest on the Debentures; and upon any such
dissolution or winding-up or liquidation or reorganization, any payment by the
Company, or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to which the holders of the Debentures
or the Trustee would be entitled to receive from the Company, except for the
provisions of this Article XVI, shall be paid by the Company or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, or by the holders of the Debentures or by
the Trustee under this Indenture if received by them or it, directly to the
holders of Senior Indebtedness of the Company (pro rata to such holders on the
basis of the respective amounts of Senior Indebtedness held by such holders, as
calculated by the Company) or their representative or representatives, or to
the trustee or trustees under any indenture pursuant to which any instruments
evidencing such Senior Indebtedness may have been issued, as their respective
interests may appear, to the extent necessary to pay such Senior Indebtedness
in full, in money or money's worth, after giving effect to any concurrent
payment or distribution to or for the holders of such Senior Indebtedness,
before any payment or distribution is made to the holders of Debentures or to
the Trustee.

     (b)  In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in
cash, property or securities, prohibited by the foregoing, shall be received by
the Trustee before all Senior Indebtedness of the Company is paid in full, or
provision is made for such payment in money in accordance with its terms, such
payment or distribution shall be held in trust for the benefit of and shall
be paid over or delivered to the holders of such Senior Indebtedness or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Senior Indebtedness
may have been issued, as their respective interests may appear, as calculated
by the Company, for application to the payment of all Senior Indebtedness of
the Company, as the case may be, remaining unpaid to the extent necessary to
pay such Senior Indebtedness in full in money 

   57

in accordance with its terms, rafter giving effect to any concurrent payment
or distribution to or for the benefit of the holders of such Senior
Indebtedness.

     (c)  For purposes of this Article XVI, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment, the
payment of which is subordinated at least to the extent provided in this
Article XVI with respect to the Debentures to the payment of all Senior
Indebtedness of the Company, as the case may be, that may at the time be
outstanding, provided that (i) such Senior Indebtedness is assumed by the new
corporation, if any, resulting from any such reorganization or readjustment;
and (ii) the rights of the holders of such Senior Indebtedness are not, without
the consent of such holders, altered by such reorganization or readjustment.
The consolidation of the Company with, or the merger of the Company into,
another corporation or the liquidation or dissolution of the Company following
the conveyance or transfer of its property as an entirety, or substantially as
an entirety, to another corporation upon the terms and conditions provided for
in Article XII shall not be deemed a dissolution, winding-up, liquidation or
reorganization for the purposes of this Section 16.3 if such other corporation
shall, as a part of such consolidation, merger, conveyance or transfer, comply
with the conditions stated in Article XII. Nothing in Section 16.2 or in this
Section 16.3 shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 9.7.

SECTION 16.4.   SUBROGATION.

     (a)  Subject to the payment in full of all Senior Indebtedness of the
Company, the rights of the holders of the Debentures shall be subrogated to the
rights of the holders of such Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Company, as the case may
be, applicable to such Senior Indebtedness until the principal of and interest
on the Debentures shall be paid in full; and, for the purposes of such
subrogation, no payments or distributions to the holders of such Senior
Indebtedness of any cash, property or securities to which the holders of the
Debentures or the Trustee would be entitled except for the provisions of this
Article XVI, and no payment over pursuant to the provisions of this Article XVI
to or for the benefit of the holders of such Senior Indebtedness by holders of
the Debentures or the Trustee, shall, as between the Company, its creditors
other than holders of Senior Indebtedness of the Company, and the holders of
the Debentures, be deemed to be a payment by the Company to or on account of
such Senior Indebtedness.  It is understood that the provisions of this
Article XVI are and are intended solely for the purposes of defining the
relative rights of the holders of the Debentures, on the one hand, and the
holders of such Senior Indebtedness on the other hand.

     (b)  Nothing contained in this Article XVI or elsewhere in this Indenture
or in the Debentures is intended to or shall impair, as between the Company,
its creditors (other than the holders of Senior Indebtedness of the Company),
and the holders of the Debentures, the obligation of the Company, which is
absolute and unconditional, to pay to the holders of the Debentures the
principal of and interest on the 



   58

Debentures as and when the same shall become due and payable in accordance
with their terms, or is intended to or shall affect the relative rights of the
holders of the Debentures and creditors of the Company, as the case may be,
other than the holders of Senior Indebtedness of the Company, as the case may
be, nor shall anything herein or therein prevent the Trustee or the holder of
any Debenture from exercising all remedies otherwise permitted by applicable
law upon default under this Indenture, subject to the rights, if any, under
this Article XVI of the holders of such Senior Indebtedness in respect of cash,
property or securities of the Company, as the case may be, received upon the
exercise of any such remedy.

     (c)  Upon any payment or distribution of assets of the Company referred to
in this Article XVI, the Trustee, subject to the provisions of Article IX, and
the holders of the Debentures shall be entitled to conclusively rely upon any
order or decree made by any court of competent jurisdiction in which such
dissolution, winding-up, liquidation or reorganization proceedings are pending,
or a certificate of the receiver, trustee in bankruptcy, liquidation trustee,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the holders of the Debentures, for the purposes of ascertaining
the Persons entitled to participate in such distribution, the holders of Senior
Indebtedness and other indebtedness of the Company, as the case may be, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article XVI.

SECTION 16.5.   TRUSTEE TO EFFECTUATE SUBORDINATION.

     Each holder of Debentures by such holder's acceptance thereof authorizes
and directs the Trustee on such holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in this
Article XVI and appoints the Trustee such holder's attorney-in-fact for any and
all such purposes.

SECTION 16.6.   NOTICE BY COMPANY.

     (a)  The Company shall give prompt written notice to a Responsible Officer
of the Trustee of any fact known to the Company that would prohibit the making
of any payment of monies to or by the Trustee in respect of the Debentures
pursuant to the provisions of this Article XVI.  Notwithstanding the provisions
of this Article XVI or any other provision of this Indenture, the Trustee shall
not be charged with knowledge of the existence of any facts that would
prohibit the making of any payment of monies to or by the Trustee in respect of
the Debentures pursuant to the provisions of this Article XVI, unless and until
a Responsible Officer of the Trustee shall have received written notice thereof
from the Company or a holder or holders of Senior Indebtedness or from any
trustee therefor; and before the receipt of any such written notice, the
Trustee, subject to the provisions of Section 9.1, shall be entitled in all
respects to assume that no such facts exist; provided, however, that if the
Trustee shall not have received the notice provided for in this Section 16.6 at
least two Business Days prior to the date upon which by the terms hereof any
money may become payable for any purpose (including, without limitation, the
payment of the principal of or interest on any Debenture), then, anything
herein contained to the contrary 


   59

notwithstanding, the Trustee shall have full power and authority to receive
such money and to apply the same to the purposes for which they were received,
and shall not be affected by any notice to the contrary that may be received by
it within two Business Days prior to such date.

     (b)  The Trustee, subject to the provisions of Section 9.1, shall be
entitled to conclusively rely on the delivery to it of a written notice by a
Person representing himself to be a holder of Senior Indebtedness of the
Company (or a trustee on behalf of such holder) to establish that such notice
has been given by a holder of such Senior Indebtedness or a trustee on behalf
of any such holder or holders.  In the event that the Trustee determines in
good faith that further evidence is required with respect to the right of any
Person as a holder of such Senior Indebtedness to participate in any payment or
distribution pursuant to this Article XVI, the Trustee may request such Person
to furnish evidence to the reasonable satisfaction of the Trustee as to the
amount of such Senior Indebtedness held by such Person, the extent to which
such Person is entitled to participate in such payment or distribution and any
other facts pertinent to the rights of such Person under this Article XVI, and,
if such evidence is not furnished, the Trustee may defer any payment to such
Person pending judicial determination as to the right of such Person to receive
such payment.

SECTION 16.7.   RIGHTS OF TRUSTEE; HOLDERS OF SENIOR INDEBTEDNESS.

     (a)  The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article XVI in respect of any Senior Indebtedness at
any time held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.  The Trustee's right to compensation and
reimbursement of expenses as set forth in Section 9.7 shall not be subject to
the subordination provisions of this Article XVI.

     (b)  With respect to the holders of Senior Indebtedness of the Company,
the Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article XVI, and no implied
covenants or obligations with respect to the holders of such Senior
Indebtedness shall be read into this Indenture against the Trustee. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of such
Senior Indebtedness and, subject to the provisions of Section 9.1, the Trustee
shall not be liable to any holder of such Senior Indebtedness if it shall pay
over or deliver to holders of Debentures, the Company or any other Person money
or assets to which any holder of such Senior Indebtedness shall be entitled by
virtue of this Article XVI or otherwise.

SECTION 16.8.   SUBORDINATION MAY NOT BE IMPAIRED.

     (a)  No right of any present or future holder of any Senior Indebtedness
of the Company to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act, in good faith, by any such holder,
or by any noncompliance by the Company with the terms, provisions and covenants
of this Indenture, 



   60

regardless of any knowledge thereof that any such holder may have or otherwise 
be charged with.

     (b)  Without in any way limiting the generality of Section 16.8(a), the
holders of Senior Indebtedness of the Company may, at any time and from time to
time, without the consent of or notice to the Trustee or the holders of the
Debentures, without incurring responsibility to the holders of the Debentures
and without impairing or releasing the subordination provided in this Article
XVI or the obligations hereunder of the holders of the Debentures to the
holders of such Senior Indebtedness, do any one or more of the following:  (i)
change the manner, place or terms of payment or extend the time of payment of,
or renew or alter, such Senior Indebtedness, or otherwise amend or supplement
in any manner such Senior Indebtedness or any instrument evidencing the same or
any agreement under which such Senior Indebtedness is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing such Senior Indebtedness; (iii) release any Person liable in
any manner for the collection of such Senior Indebtedness; and (iv) exercise or
refrain from exercising any rights against the Company and any other Person.

     IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be
duly executed, and their respective corporate seals to be hereunto affixed and
attested, all as of the day and year first above written.

                          8.50% SUBORDINATED DEBENTURE
    

                             DUE DECEMBER 31, 2027

   
Capitol Bancorp Ltd., a Michigan corporation, (the "Company," which term
includes any successor corporation under the Indenture hereinafter referred
to), for value received, hereby promises to pay to The First National Bank of
Chicago, as Trustee, or registered assigns, the principal sum of Twenty Six
Million Eighty Two Thousand Four Hundred Eighty dollars ($26,082,480.00) on
December 31, 2027 (the "Stated Maturity"), and to pay  interest on said
principal sum from December 19, 1997, or from the most recent  interest payment
date (each such date, an "Interest Payment Date") to which  interest has been
paid or duly provided for, quarterly (subject to deferral as set forth herein)
in arrears on March 31, June 30, September 30 and December 31 of each year
commencing  March 31, 1998 at the rate of 8.50% per annum until the principal
hereof shall have become due and payable, and on any overdue principal and
(without duplication) on any overdue installment of interest at the same rate
per annum compounded quarterly.  The amount of interest payable on any Interest
Payment Date shall be computed on the basis of a 360-day year of twelve 30-day
months.  The amount of interest for any partial period shall be computed on the
basis of the number of days elapsed in a 360-day year of twelve 30-day months. 
In the event that any date on which interest is payable on this Debenture is
not a business day, then payment of interest payable on such date shall be made
on the next succeeding day that is a Business Day (as defined in the Indenture)
(and without any interest or other payment in respect of any such delay) with
the same force and effect as if made on such date.  The interest installment so
payable, and punctually paid or duly provided for, on any Interest Payment Date
shall, as provided in the Indenture, be paid to the person in whose name this
Debenture (or one or more Predecessor Debentures, as defined in the Indenture)
is registered at the close of business on the regular record date for such
interest installment, which shall be the fifteenth day of the last month of the
calendar quarter in which such Interest Payment Date occurs unless otherwise
provided in the Indenture.  The principal of and the interest on this Debenture
shall be payable at the office or agency of the Trustee maintained for that
purpose in any coin or currency of the United States of America that at the
time of payment is legal tender for payment of public and private debts;
provided, however, that payment of interest may be made at the option of the
Company by check mailed to the registered holder at such address as shall       
appear in the Debenture Register.  Notwithstanding the foregoing, so long as
the holder of this Debenture is the Trustee, the payment of the principal of
and interest on this Debenture shall be made at such place and to such account
as may be designated by the Trustee.
    

     The Stated Maturity may be shortened at any time by the Company to any
date not earlier than December 31, 2002, subject to the Company having received
prior approval of the Federal Reserve if then required under applicable capital
guidelines or policies of the Federal Reserve.  Such date may also be extended
at any time at the election of the Company for one or more periods, but in no
event to a date later than December 31, 2036, subject to certain limitations
described in the Indenture.

Debenture, by accepting the same, (a) agrees to and shall be bound by such

such action as may be necessary or appropriate to acknowledge or effectuate the
subordination so provided; and (c) appoints the Trustee his or her
attorney-in-fact for any and all such purposes.  Each holder hereof, by his or
her acceptance hereof, hereby waives all notice of the acceptance of the
subordination provisions contained herein and in the Indenture by each holder

and such continued provisions shall for all purposes have the same effect as
though fully set forth at this place.

                          8.50% SUBORDINATED DEBENTURE
                                  (CONTINUED)
    

   
     This Debenture is one of the subordinated debentures of the Company (the
"Debentures"), all issued or to be issued under and pursuant to an Indenture
dated as of December 18, 1997 (the "Indenture"), duly executed and delivered
between the Company and The First National Bank of Chicago, as Trustee (the
"Trustee"), to which Indenture reference is hereby made for a description of
the rights, limitations of rights, obligations, duties and immunities
thereunder of the Trustee, the Company and the holders of the Debentures.  The
Debentures are limited in aggregate principal amount as specified in the
Indenture.
    

      Company shall have the right, as set forth in the Indenture, to redeem
this Debenture at the option of the Company, without premium or penalty, in
whole or in part at any time on or after December 31, 2002 (an "Optional
Redemption"), or at any time in certain circumstances upon the occurrence of a
Special Event (as defined in the Indenture), at a redemption price (the
"Redemption Price") equal to 100% of the principal amount hereof plus any
accrued but unpaid interest hereon, to the date of such redemption.  Any
redemption pursuant to this paragraph shall be made upon not less than 30 days
nor more than 60 days notice, at the Redemption Price.  The Redemption Price
shall be paid at the time and in the manner provided therefor in the Indenture.
If the Debentures are only partially redeemed by the Company pursuant to an
Optional Redemption, the Debentures shall be redeemed pro rata or by lot or by
any other method utilized by the Trustee as described in the Indenture.  In the
event of an Optional Redemption of this Debenture in part only, a new Debenture
or Debentures for the unredeemed portion hereof shall be issued in the name of
the holder hereof upon the cancellation hereof.





   64

     In case an Event of Default (as defined in the Indenture), shall have
occurred and be continuing, the principal of all of the Debentures may be
declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the
Indenture.

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the holders of not less than a majority in aggregate
principal amount of the Debentures at the time Outstanding (as defined in the
Indenture), to execute supplemental indentures for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture or of any supplemental indenture or of modifying in any manner
the rights of the holders of the Debentures; provided, however, that no such
supplemental indenture shall (i) extend the fixed maturity of the Debentures
except as provided in the Indenture, or reduce the principal amount thereof, or
reduce the rate or extend the time of payment of interest thereon, without the
consent of the holder of each Debenture so affected; or (ii) reduce the
aforesaid percentage of Debentures, the holders of which are required to
consent to any such supplemental indenture, without the consent of the holders
of each Debenture then outstanding and affected thereby.  The Indenture also
contains provisions permitting the holders of a majority in aggregate principal
amount of the Debentures at the time outstanding, on behalf of all of the
holders of the Debentures, to waive any past default in the performance of any
of the covenants contained in the Indenture, or established pursuant to the
Indenture, and its consequences, except a default in the payment of the
principal of or interest on any of the Debentures.  Any such consent or waiver
by the registered holder of this Debenture (unless revoked as provided in the
Indenture) shall be conclusive and binding upon such holder and upon all future
holders and owners of this Debenture and of any Debenture issued in exchange
herefor or in place hereof (whether by registration of transfer or otherwise),
irrespective of whether or not any notation of such consent or waiver is made
upon this Debenture.

     No reference herein to the Indenture and no provision of this Debenture or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal and interest on this Debenture
at the time and place and at the rate and in the money herein prescribed.

     The Company, as further described in the Indenture, shall have the right
at any time during the term of the Debentures and from time to time to extend
the interest payment period of such Debentures for up to 20 consecutive
quarters (each, an "Extended Interest Payment Period"), at the end of which
period the Company shall pay all interest then accrued and unpaid (together
with interest thereon at the rate specified for the Debentures to the extent
that payment of such interest is enforceable under applicable law).  Before the
termination of any such Extended Interest Payment Period, the Company may
further extend such



   65


Extended Interest Payment Period, provided that such Extended Interest Payment
Period together with all such further extensions thereof shall not exceed 20
consecutive quarters.  At the termination of any such Extended Interest Payment
Period and upon the payment of all accrued and unpaid interest and any
additional amounts then due, the Company may commence a new Extended Interest
Payment Period.

     As provided in the Indenture, and subject to certain limitations therein
set forth, this Debenture is transferable by the registered holder hereof on
the Debenture Register (as defined in the Indenture) of the Company, upon
surrender of this Debenture for registration of transfer at the office or
agency of the Trustee accompanied by a written instrument or instruments of
transfer in form satisfactory to the Company or the Trustee duly executed by
the registered holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Debentures of authorized denominations and for the
same aggregate principal amount shall be issued to the designated transferee or
transferees.  No service charge shall be made for any such transfer, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in relation thereto.

     Prior to due presentment for registration of transfer of this Debenture,
the Company, the Trustee, any Paying Agent (as defined in the Indenture) and
the Debenture Registrar may deem and treat the registered holder hereof as the
absolute owner hereof (whether or not this Debenture shall be overdue and
notwithstanding any notice of ownership or writing hereon made by anyone other
than the Debenture Registrar) for the purpose of receiving payment of or on
account of the principal hereof and interest due hereon and for all other
purposes, and neither the Company nor the Trustee nor any Paying Agent nor any
Debentures Registrar shall be affected by any notice to the contrary.

     No recourse shall be had for the payment of the principal of or the
interest on this Debenture, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of
any assessment or penalty or otherwise, all such liability being, by the
acceptance hereof and as part of the consideration for the issuance hereof,
expressly waived and released.

     The Debentures are issuable only in registered form without coupons in
denominations of $10 and any integral multiple thereof (or such lesser
denomination and any integral multiple thereof as may be deemed necessary by
the Company for the purpose of maintaining the eligibility of the Debentures
for quotation on the Nasdaq Stock Market's National Market or any successor
thereto).

     All terms used in this Debenture that are defined in the Indenture shall
have the meanings assigned to them in the Indenture.
