Debentures,  the Trust or the  Property  Trustee is  required  to pay any taxes,
duties,  assessments  or  governmental  charges of whatever  nature  (other than
withholding  taxes) imposed by the United States, or any other taxing authority,

affixed, imprinted or otherwise reproduced on the Debentures. The Debentures may
contain such notations,  legends or endorsements required by law, stock exchange
rule or usage.  Each Debenture shall be dated the date of its  authentication by
the Trustee.

         (b) A Debenture shall not be valid until  authenticated  manually by an
authorized  signatory  of  the  Trustee,  or by an  Authenticating  Agent.  Such
signature shall be conclusive  evidence that the Debenture so authenticated  has
been duly authenticated and delivered  hereunder and that the holder is entitled
to the benefits of this Indenture.

         (c) At any time and from time to time after the  execution and delivery
of this Indenture, the Company may deliver Debentures executed by the Company to
the Trustee for authentication, together with a written order of the Company for
the  authentication  and  delivery of such  Debentures

                                     - 12 -

signed by its Chairman, President or any Vice President and its Treasurer or any
Assistant Treasurer, and the Trustee in accordance with such written order shall
authenticate and deliver such Debentures.

         (d) In  authenticating  such  Debentures  and accepting the  additional
responsibilities  under this  Indenture  in  relation  to such  Debentures,  the
Trustee  shall be  entitled to receive,  and  (subject to Section  9.1) shall be
fully protected in relying upon, an Opinion of Counsel stating that the form and
terms thereof have been  established  in conformity  with the provisions of this
Indenture.

         (e) The Trustee shall not be required to  authenticate  such Debentures
if the issue of such  Debentures  pursuant to this  Indenture  shall  affect the
Trustee's  own  rights,  duties  or  immunities  under the  Debentures  and this
Indenture  or  otherwise in a manner that is not  reasonably  acceptable  to the
Trustee.

SECTION 2.7       REGISTRATION OF TRANSFER AND EXCHANGE.

         (a) Debentures may be exchanged upon presentation thereof at the office
or  agency  of the  Company  designated  for  such  purpose  in the  Borough  of
Manhattan,  The City of New York, or at the office of the  Debenture  Registrar,
for other Debentures and for a like aggregate  principal amount in denominations
of integral  multiples of $25, upon payment of a sum sufficient to cover any tax
or other  governmental  charge in  relation  thereto,  all as  provided  in this
Section 2.7. In respect of any  Debentures  so  surrendered  for  exchange,  the
Company shall execute,  the Trustee shall authenticate and such office or agency
shall  deliver  in  exchange  therefor  the  Debenture  or  Debentures  that the
Debentureholder  making the  exchange  shall be  entitled  to  receive,  bearing
numbers not contemporaneously outstanding.

         (b) The  Company  shall  keep,  or cause to be kept,  at its  office or
agency designated for such purpose in the Borough of Manhattan,  The City of New
York,  or at the  office  of the  Debenture  Registrar  or such  other  location
designated  by the Company a register or  registers  (herein  referred to as the
"Debenture Register") in which, subject to such reasonable regulations as it may
prescribe,  the Company  shall  register  the  Debentures  and the  transfers of
Debentures  as in this  Article II provided  and which at all  reasonable  times
shall be open for  inspection  by the Trustee.  The registrar for the purpose of
registering  Debentures  and transfer of  Debentures  as herein  provided  shall
initially  be the Trustee and  thereafter  as may be appointed by the Company as
authorized by Board Resolution (the "Debenture  Registrar").  Upon surrender for
transfer of any Debenture at the office or agency of the Company  designated for
such purpose, the Company shall execute, the Trustee shall authenticate and such
office or agency shall deliver in the name of the  transferee  or  transferees a
new  Debenture  or  Debentures  for  a  like  aggregate  principal  amount.  All
Debentures presented or surrendered for exchange or registration of transfer, as
provided  in this  Section  2.7,  shall be  accompanied  (if so  required by the
Company or the Debenture  Registrar) by a written  instrument or  instruments of
transfer,  in form satisfactory to the Company or the Debenture Registrar,  duly
executed by the registered  holder or by such holder's duly authorized  attorney
in writing.

         (c) No service charge shall be made for any exchange or registration of
transfer  of  Debentures,  or  issue  of  new  Debentures  in  case  of  partial
redemption, but the Company may require payment of a sum sufficient to cover any
tax or other  governmental  charge in  relation  thereto,  other

                                     - 13 -

than exchanges  pursuant to Section 2.8, the second paragraph of Section 3.5 and
Section 11.4 not involving any transfer.

         (d) The  Company  shall  not be  required  (i) to  issue,  exchange  or
register the transfer of any Debentures during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of  redemption  of
less than all the Outstanding  Debentures and ending at the close of business on
the day of such  mailing;  nor (ii) to register  the transfer of or exchange any
Debentures or portions thereof called for redemption.

         (e)  Debentures  may only be  transferred,  in  whole  or in  part,  in
accordance  with the  terms and  conditions  set  forth in this  Indenture.  Any
transfer or purported transfer of any Debenture not made in accordance with this
Indenture shall be null and void.

SECTION 2.8 TEMPORARY DEBENTURES.

         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, 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
in the  Borough  of  Manhattan,  The City of New  York,  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,  stolen  or  mutilated.  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 

                                     - 14 -

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  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 

                                     - 15 -

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  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,  policies or
regulations 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.

                                     - 16 -

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,
policies or regulations of the Federal Reserve,  if a Special Event has occurred
and is continuing,  then,  notwithstanding Section 3.3(a) but subject to Section
3.3(b),  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. The Redemption Price shall
be paid prior to 12:00 noon,  New York time,  on 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 September
30, 2003,  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
National Market_ or any national  securities  exchange or other  organization on
which  the  Preferred  Securities  are then  listed,  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 will 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 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 office or agency
of the  Company  in the  Borough  of  Manhattan,  The City of New York or 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,  pro rata or by lot or in such other
manner as it shall deem  appropriate and fair in its discretion,  the portion or
portions (equal to $25 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  Chairman,  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 

                                     - 18 -

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  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.

         The  Company  shall have the  right,  at any time and from time to time
during the term of the  Debentures  so long as no Event of Default has  occurred
and is  continuing,  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 or end on a
date other than an Interest  Payment Date. To the extent permitted by applicable
law,  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  ("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 Interest and Compounded Interest (together,
"Deferred  

                                     - 19 -

Interest") 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
so long as no Event of Default has occurred  and is  continuing,  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 or
end on a date other than an Interest  Payment Date.  Upon the termination of any
Extended  Interest Payment Period and upon the payment of all Deferred  Interest
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  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 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  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  and be
continuing  any Event of Default,  then (a) the Company shall not declare or pay
any dividend on, make any  distributions  with respect to, or redeem,  purchase,
acquire or make a liquidation  payment with respect to, any of its capital stock
(other than as a result of a  reclassification  of its capital stock for another
class of its  capital  stock);  (b) the  Company  shall not make any  payment of
interest,  principal or premium, if any, or repay, repurchase or redeem any debt
securities  issued by the  Company  which  rank pari passu with or

                                     - 20 -

junior to the  Debentures  or make any  guarantee  payment  with  respect to any
guarantee by the Company of the debt securities of any subsidiary of the Company

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.

principal  of and  interest on the  Debentures  at the time and place and in the
manner provided herein.

SECTION 5.2 MAINTENANCE OF AGENCY.

         So long as any of the Debentures remain Outstanding,  the Company shall
maintain, or shall cause to be maintained, an office or agency in the Borough of
Manhattan,  The City of New York, and at such other 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

designation  or  rescission  shall in any  manner  relieve  the  Company  of its
obligation  to maintain  any such office or agency in the Borough of  Manhattan,
The City of New York, for the purposes above  mentioned.  The Company shall give
the Trustee prompt written notice of any such designation or rescission thereof.

         (a) The Company shall be the initial 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.

         (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.

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.

Indenture and such period, or any extension thereof,  shall be continuing,  then
(a) the Company shall not declare or pay any dividend on, make any distributions
with respect to, or redeem, purchase, acquire or make a liquidation payment with
respect  to,  any  of  its  capital   stock   (other  than  as  a  result  of  a
reclassification  of its capital stock);  and (b) the Company shall not make any
payment of  interest,  principal  or premium,  if any, or repay,  repurchase  or
redeem any debt  securities  issued by the Company which rank pari passu with or
junior to the  Debentures  or make any  guarantee  payments  with respect to any
guarantee by the Company of the debt securities of any subsidiary of the Company
if such guarantee ranks 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 such Trust  Securities of the Trust remain  outstanding,
the Company shall (i) maintain  100% direct or indirect  ownership of the Common

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,  policies or  regulations of the Federal

business   trust  (and  to  avoid   involuntary   termination,   winding  up  or
liquidation),  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

                                     - 23 -

beneficial  interest in the Debentures.  In connection with the  distribution of
the  Debentures to the holders of the Preferred  Securities  issued by the Trust

Debentures  on The Nasdaq  National  Market_ or on such  other  exchange  as the

         The Company  shall not at any time  insist  upon,  or plead,  or in any
manner  whatsoever claim or take the benefit or advantage of, any usury, stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performances of this Indenture,  and the Company (to
the extent that it may  lawfully do so) hereby  expressly  waives all benefit or
advantage  of any such law,  and  covenants  that it will not  hinder,  delay or
impede the execution of any power herein granted to the Trustee, but will suffer
and  permit  the  execution  of every  such power as though no such law had been
enacted.

         due and  payable,  and  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  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

                  (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
         substantially all of its property;  or (iv) makes a 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

         dissolved,  wound-up its business or otherwise terminated its existence
         except in connection with (i) the distribution of Debentures to holders
         of Trust  Securities in  liquidation  of their  interests in the Trust;
         (ii) the redemption of all of the outstanding  Trust  Securities of the
         Trust; or (iii) certain mergers, consolidations or amalgamations,  each

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.

         (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,  to  the  extent  that  such  payment  is
enforceable under applicable law, 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 9.6; 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

                                     - 27 -

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 (to the extent that payment
of such interest is enforceable  under applicable law 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  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 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 of either,  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,  

                                     - 28 -

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

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.

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

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;  (iv) the

                                     - 29 -

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 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 on  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

                                     - 30 -

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
Officers of 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 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.

SECTION 7.8 DIRECT ACTION; RIGHT OF SET-OFF

         In the event that an Event of Default has  occurred  and is  continuing
and such event is  attributable to the failure of the Company to pay interest on
or principal of the  Debentures on the payment date on which such payment is due
and  payable,  then a holder  of  Preferred  Securities  may  institute  a legal
proceeding  directly  against  the Company  for  enforcement  of payment to such
holder of the  principal  of or interest on such  Debentures  having a principal
amount equal to the aggregate

                                     - 31 -

Liquidation  Amount of the  Preferred  Securities  of such  holders  (a  "Direct
Action").  In connection with such Direct Action,  the Company will have a right
of set-off under this Indenture to the extent of any payment made by the Company
to such holder of the Preferred Securities with respect to such Direct Action.

         Debentures in the aggregate  principal  amount of $28,350,516 may, upon

Agreement, dated September 24, 1998, by and among the Company, the Trust, EVEREN

                                   ARTICLE IX

                             CONCERNING THE TRUSTEE

SECTION 9.1 CERTAIN DUTIES AND RESPONSIBILITIES OF THE TRUSTEE.

         (a) The  Trustee,  prior to the  occurrence  of an Event of Default and
after  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 the rights and powers vested in it by this  Indenture,  and use
the same degree of care and skill in their  exercise,  as a prudent Person would
exercise or use under the circumstances in the conduct of its own affairs.

                                     - 32 -

         (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:

                  (i) 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:

                           (1) 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

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

                  (ii) 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;

                  (iii) 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

                  (iv) 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.

                                     - 33 -

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
Securities, 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  default in the payment of the  principal  or interest
(including  any  Additional  Interest) 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)(3),  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, 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 its 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,  

                                     - 34 -

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

         (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 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.

                                     - 35 -

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  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 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. (1)

         (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.

                                     - 36 -

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

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 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 9.9, 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

                                     - 37 -

                  (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 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.

                                     - 38 -

         (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
paragraph (a) of this Section 9.12.

         (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   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

to Section 311(a) of the Trust Indenture Act to the extent included therein.


                                    ARTICLE X

                         CONCERNING THE DEBENTUREHOLDERS

                                     - 39 -

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 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.

                                     - 40 -

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 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.

                             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

         (b) to comply with Article X;

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

         (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; (1)

         (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, only 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

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.

                                     - 42 -

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 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.

                                     - 43 -

SECTION 11.5 EXECUTION OF SUPPLEMENTAL INDENTURES.

         (a)  Upon the  request  of the  Company,  accompanied  by  their  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.

         (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.

case may be), or successive  consolidations or mergers in which the Company,  as
the case may be, or its successor or successors shall be a party or parties,  or

successors)  authorized to acquire and operate the same; provided,  however, the
Company  hereby  covenants  and agrees  that,  (i) upon any such  consolidation,

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

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

successor  Person is organized  under the laws of the United States or any state

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 Company, as the case may be,
such successor  corporation shall succeed to and be substituted for the Company,

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

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,

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

                                     - 49 -

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 15.1 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.

         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 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,  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.

                           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 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 

                                     - 51 -

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,  and 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 in accordance  with its terms,  after
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.

                                     - 52 -

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  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.

                                     - 53 -

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 THE 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 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

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

SECTION 16.7 RIGHTS OF THE 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 the 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,  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 the  foregoing
paragraph,  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.

         Wintrust Financial Corporation, an Illinois corporation (the "Company,"
which term includes any successor  corporation  under the Indenture  hereinafter
referred to), for value received,  hereby promises to pay to, _______________ or
registered   assigns,    the   principal   sum   of    _________________________
($___________)  on  September  30,  2028  (the  "Stated  Maturity"),  and to pay
interest on said  principal sum from September 29, 1998, 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, June, September and December of each year
commencing December 31, 1998, at the rate of 9.00% per annum until the principal
hereof  shall have  become due and  payable,  and on any overdue  principal  and
(without  duplication  and to the  extent  that  payment  of  such  interest  is
enforceable under applicable law) 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 (and without any
interest or other  payment in respect of any such delay)  except  that,  if such
business day is in the next succeeding  calendar year,  payment of such interest
will be made on the immediately  preceding  business day, in each case, 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 said Indenture)
is  registered  at the close of  business  on the  regular  record date for such
interest  installment,  which shall be the close of business on the business day
next  preceding  such  Interest  Payment Date unless  otherwise  provided in the
Indenture.  Any such interest  installment  not punctually paid or duly provided
for shall  forthwith  cease to be  payable  to the  registered  holders  on such
regular  record date and may be paid to the Person in whose name this  Debenture
(or one or more  Predecessor  Debentures) is registered at the close of business
on a special  record  date to be fixed by the  Trustee  for the  payment of such
defaulted  interest,  notice

                                      A-1

whereof shall be given to the registered holders of the Debentures not less than
10 days prior to such  special  record  date,  or may be paid at any time in any
other lawful manner not  inconsistent  with the  requirements  of any securities
exchange on which the Debentures  may be listed,  and upon such notice as may be
required by such  exchange,  all as more fully  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
Property 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 September 30, 2003, subject to the Company having received
prior approval of the Federal Reserve if then required under applicable  capital
guidelines,  policies or regulations 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  September  30,  2047,  subject to certain
limitations described in the Indenture.

         The indebtedness evidenced by this Debenture is, to the extent provided
in the  Indenture,  subordinate  and  junior  in right of  payment  to the prior
payment in full of all Senior Indebtedness, and this Debenture is issued subject
to the  provisions of the Indenture  with respect  thereto.  Each holder of this
Debenture,  by  accepting  the  same,  (a)  agrees to and shall be bound by such
provisions;  (b) authorizes and directs the Trustee on his or her behalf to take
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 of
Senior Indebtedness,  whether now outstanding or hereafter incurred,  and waives
reliance by each such holder upon said provisions.

         This Debenture shall not be entitled to any benefit under the Indenture
hereinafter referred to, be valid or become obligatory for any purpose until the
Certificate of  Authentication  hereon shall have been signed by or on behalf of
the Trustee.

         The  provisions  of this  Debenture  are  continued on the reverse side
hereof and such continued provisions shall for all purposes have the same effect
as though fully set forth at this place.


                                      A-2

         IN WITNESS  WHEREOF,  the  Company  has caused  this  instrument  to be
executed.

                          9.00% SUBORDINATED DEBENTURE
                                   (CONTINUED)


         This  Debenture is one of the  subordinated  debentures  of the Company
(herein sometimes referred to as the "Debentures"),  specified in the Indenture,
all  issued  or to be issued  under and  pursuant  to an  Indenture  dated as of
September 29, 1998 (the  "Indenture")  duly  executed and delivered  between the
Company and  Wilmington  Trust  Company,  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.

         Because of the  occurrence  and  continuation  of a Special  Event,  in
certain  circumstances,  this  Debenture  may  become  due  and  payable  at the
principal  amount together with any interest  accrued  thereon (the  "Redemption
Price").  The  Redemption  Price  shall be paid  prior to  12:00  noon,  Eastern
Standard Time,  time, on the date of such  redemption or at such earlier time as
the  Company  determines.  The  Company  shall  have the  right 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  September 30, 2003 (an "Optional  Redemption"),
or at any time in certain  circumstances upon the occurrence of a Special Event,
at a Redemption Price equal to 100% of the principal amount plus any accrued but
unpaid interest, 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.  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.

         In the  event of  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.

         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

                                      A-5

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.

         Provided  certain  conditions are met, the Company 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, so long as no Event of Default shall
have occurred and be  continuing,  the Company may further  extend such Extended
Interest  Payment Period,  provided that such Extended  Interest  Payment Period
together  with  all  such  further   extensions  thereof  shall  not  exceed  20
consecutive  quarters,  extend beyond the Stated Maturity or end on a date other
than an Interest Payment Date. 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 and subject to the foregoing conditions, 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  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  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

                                      A-6

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  Debenture  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 $25 and any integral multiple thereof.

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