notice, consent, waiver or other action, only Securities which the Trustee
knows to be so owned shall be so disregarded. Securities so owned which have

for in Section 1004) shall include,

representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or opinion of counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the

Company, unless such counsel knows, or in the exercise of reasonable care

SECTION 104.  Acts of Holders; Record Dates.

      Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given, made or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

      The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by
a certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such
instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

      The ownership of Securities shall be proved by the Security Register.

      Without limiting the generality of the foregoing, a Holder, including a
Depositary that is a Holder of a Global Security, may make, give or take, by
proxy or proxies, duly appointed in writing, any request, demand,
authorization, direction, notice, consent,





                                      -10-
<PAGE>   21
waiver or other action provided or permitted in this Indenture to be made,
given or taken by Holders, and a Depositary that is a Holder of a Global
Security may provide its proxy or proxies to the beneficial owners of interests
in any such Global Security.

      Any request, demand, authorization, direction, notice, consent, waiver or
other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

      The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be cancelled and of no effect), and nothing in this paragraph shall be
construed to render ineffective any action taken by Holders of the requisite
principal amount of Outstanding Securities of the relevant series on the date
such action is taken. Promptly after any record date is set pursuant to this
paragraph, the Company, at its own expense, shall cause notice of such record
date, the proposed action by Holders and the applicable Expiration Date to be
given to the Trustee in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 106.

      The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
join in the giving or making of (i) any Notice of Default, (ii) any declaration
of acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this





                                      -11-
<PAGE>   22
paragraph shall be construed to prevent the Trustee from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically
and with no action by any Person be cancelled and of no effect), and nothing in
this paragraph shall be construed to render ineffective any action taken by
Holders of the requisite principal amount of Outstanding Securities of the
relevant series on the date such action is taken. Promptly after any record
date is set pursuant to this paragraph, the Trustee, at the Company's expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Company in writing and to each
Holder of Securities of the relevant series in the manner set forth in Section
106.

      With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

      Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard
to all or any part of the principal amount of such Security or by one or more
duly appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.


SECTION 105.  Notices, Etc., to Trustee and Company.

      Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

         (1)  the Trustee by any Holder or by the Company shall be sufficient
   for every purpose hereunder if made, given, furnished or filed in writing to
   or with the Trustee at its Corporate Trust Office, Attention: Corporate
   Trust Administration, which office is 101 Barclay Street, Floor 21W, New
   York, New York 10286 or

         (2)  the Company by the Trustee or by any Holder shall be sufficient
   for every purpose hereunder (unless otherwise herein expressly provided) if
   in writing and mailed, first-class postage prepaid, to the Company addressed
   to it at the address of its principal office specified in the first
   paragraph of this instrument or at any other address previously furnished in
   writing to the Trustee by the Company.

<PAGE>   23
SECTION 106.  Notice to Holders; Waiver.

      Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in
any notice so mailed, to any particular Holder shall affect the sufficiency of
such notice with respect to other Holders. Where this Indenture provides for
notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such
waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

      In case by reason of the suspension of regular mail service or by reason
of any other cause it shall be impracticable to give such notice by mail, then
such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.


SECTION 107.  Conflict with Trust Indenture Act.

      If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act which is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
which may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.


SECTION 108.  Effect of Headings and Table of Contents.

      The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.


SECTION 109.  Successors and Assigns.

      All covenants and agreements in this Indenture by the Company shall bind
its successors and assigns, whether so expressed or not.

SECTION 110.  Separability Clause.

      In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.


SECTION 111.  Benefits of Indenture.

      Nothing in this Indenture or in the Securities, express or implied, shall
give to any Person, other than the parties hereto and their successors
hereunder, the holders of Senior Indebtedness and the Holders, any benefit or
any legal or equitable right, remedy or claim under this Indenture.


SECTION 112.  Governing Law.

      This Indenture and the Securities shall be governed by and construed in
accordance with the law of the State of New York.


SECTION 113.  Legal Holidays.

      In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security or the last date on which a Holder has the right to
convert his Securities shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities (other than a provision of any Security which specifically states
that such provision shall apply in lieu of this Section)) payment of interest
or principal (and premium, if any) or conversion of the Securities need not be
made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity or on such last day for conversion.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

      Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

      Each Security shall be dated the date of its authentication.

      No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered





                                      -28-

hereunder. Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 309, for all purposes of this Indenture such Security shall
be deemed never to have been authenticated and delivered hereunder and shall
never be entitled to the benefits of this Indenture.


SECTION 304.  Temporary Securities.

      Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

      If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in a Place of Payment for that series, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series, the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor one or more definitive
Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series and tenor.


SECTION 305.  Registration, Registration of Transfer and Exchange.

      The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is
hereby appointed "Security Registrar" for the purpose of registering Securities
and transfers of Securities as herein provided.

      Upon surrender for registration of transfer of any Security of a series
at the office or agency of the Company in a Place of Payment for that series,
the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated





                                      -29-
<PAGE>   40
transferee or transferees, one or more new Securities of the same series, of
any authorized denominations and of like tenor and aggregate principal amount.

      At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange
is entitled to receive.

      All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

      Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

      No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

      If the Securities of any series (or of any series and specified tenor)
are to be redeemed in part, the Company shall not be required (A) to issue,
register the transfer of or exchange any Securities of that series (or of that
series and specified tenor, as the case may be) during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 1103
and ending at the close of business on the day of such mailing, or (B) to
register the transfer of or exchange any Security so selected for redemption in
whole or in part, except the unredeemed portion of any Security being redeemed
in part.

      The provisions of Clauses (1), (2), (3) and (4) below shall apply only to
Global Securities:

       (1) Each Global Security authenticated under this Indenture shall be
   registered in the name of the Depositary designated for such Global Security
   or a nominee thereof and delivered to such Depositary or a nominee thereof
   or custodian therefor, and each such Global Security shall constitute a
   single Security for all purposes of this Indenture.





                                      -30-
<PAGE>   41
       (2) Notwithstanding any other provision in this Indenture, no Global
   Security may be exchanged in whole or in part for Securities registered, and
   no transfer of a Global Security in whole or in part may be registered, in
   the name of any Person other than the Depositary for such Global Security or
   a nominee thereof unless (A) such Depositary (i) has notified the Company
   that it is unwilling or unable to continue as Depositary for such Global
   Security and no Successor Depositary has been appointed within 90 days or
   (ii) has ceased to be a clearing agency registered under the Exchange Act,
   (B) there shall have occurred and be continuing an Event of Default with
   respect to such Global Security, (C) the Company, in its sole discretion,
   has determined that Securities of any series issued in the form of one or
   more Global Securities shall no longer be represented by such Global
   Security or Global Securities or (D) there shall exist such circumstances,
   if any, in addition to or in lieu of the foregoing as have been specified
   for this purpose as contemplated by Section 301.

       (3) Subject to Clause (2) above, any exchange of a Global Security for
   other Securities may be made in whole or in part, and all Securities issued
   in exchange for a Global Security or any portion thereof shall be registered
   in such names as the Depositary for such Global Security shall direct.

       (4) Every Security authenticated and delivered upon registration of
   transfer of, or in exchange for or in lieu of, a Global Security or any
   portion thereof, whether pursuant to this Section, Section 304, 306, 906 or
   1107 or otherwise, shall be authenticated and delivered in the form of, and
   shall be, a Global Security, unless such Security is registered in the name
   of a Person other than the Depositary for such Global Security or a nominee
   thereof.


SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.

      If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

      If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security and
(ii) such security or indemnity as may be required by them to save each of them
and any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

      In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.





                                      -31-
<PAGE>   42
      Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses
(including the fees and expenses of the Trustee) connected therewith.

      Every new Security of any series issued pursuant to this Section in lieu
of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall
be entitled to all the benefits of this Indenture equally and proportionately
with any and all other Securities of that series duly issued hereunder.

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


SECTION 307.  Payment of Interest; Interest Rights Preserved.

      Except as otherwise provided as contemplated by Section 301 with respect
to any series of Securities, interest on any Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be
paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

      Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

         (1)  The Company may elect to make payment of any Defaulted Interest
      to the Persons in whose names the Securities of such series (or their
      respective Predecessor Securities) are registered at the close of
      business on a Special Record Date for the payment of such Defaulted
      Interest, which shall be fixed in the following manner. The Company shall
      notify the Trustee in writing of the amount of Defaulted Interest
      proposed to be paid on each Security of such series and the date of the
      proposed payment, and at the same time the Company shall deposit with the
      Trustee an amount of money equal to the aggregate amount proposed to be
      paid in respect of such Defaulted Interest or shall make arrangements
      satisfactory to the Trustee for such deposit prior to the date of the
      proposed payment, such money when deposited to be held in trust for the
      benefit of the Persons entitled to such Defaulted Interest as in this
      Clause provided. Thereupon the Trustee shall fix a Special Record Date
      for the payment of such Defaulted Interest which shall be not more than
      15 days and not less than 10 days prior to the date of the proposed
      payment and not less than 10 days after the receipt by the Trustee of the
      notice of





                                      -32-
<PAGE>   43
   the proposed payment. The Trustee shall promptly notify the Company of such
   Special Record Date and, in the name and at the expense of the Company,
   shall cause notice of the proposed payment of such Defaulted Interest and
   the Special Record Date therefor to be given to each Holder of Securities of
   such series in the manner set forth in Section 106, not less than 10 days
   prior to such Special Record Date. Notice of the proposed payment of such
   Defaulted Interest and the Special Record Date therefor having been so
   mailed, such Defaulted Interest shall be paid to the Persons in whose names
   the Securities of such series (or their respective Predecessor Securities)
   are registered at the close of business on such Special Record Date and
   shall no longer be payable pursuant to the following Clause (2).

         (2)  The Company may make payment of any Defaulted Interest on the
   Securities of any series in any other lawful manner not inconsistent with
   the requirements of any securities exchange on which such Securities may
   be listed, and upon such notice as may be required by such exchange, if,
   after notice given by the Company to the Trustee of the proposed payment
   pursuant to this Clause, such manner of payment shall be deemed
   practicable by the Trustee.

      Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

      In the case of any convertible Security which is converted after any
Regular Record Date and on or prior to the next succeeding Interest Payment
Date (other than any Security whose Maturity is prior to such Interest Payment
Date), interest whose Stated Maturity is on such Interest Payment Date shall be
payable on such Interest Payment Date notwithstanding such conversion, and such
interest (whether or not punctually paid or duly provided for) shall be paid to
the Person in whose name that Security (or one or more Predecessor Securities)
is registered at the close of business on such Regular Record Date.  Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any convertible Security which is converted, interest whose Stated Maturity
is after the date of conversion of such Security shall not be payable.


SECTION 308.  Persons Deemed Owners.

      Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Security is registered as the owner of such Security
for the purpose of receiving payment of principal of and any premium and
(subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.





                                      -33-
<PAGE>   44
SECTION 309.  Cancellation.

      All Securities surrendered for payment, redemption, registration of
transfer or exchange or conversion or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and shall be promptly cancelled by it. The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in
any manner whatsoever, and may deliver to the Trustee (or to any other Person
for delivery to the Trustee) for cancellation any Securities previously
authenticated hereunder which the Company has not issued and sold, and all
Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed of as
directed by a Company Order; provided, that the Trustee shall not be required
to destroy cancelled Securities.


SECTION 310.  Computation of Interest.

      Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

                          SATISFACTION AND DISCHARGE


SECTION 401.  Satisfaction and Discharge of Indenture.

      This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of conversion, registration of transfer or
exchange of Securities herein expressly provided for), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

      (1)  either

         (A)  all Securities theretofore authenticated and delivered (other
      than (i) Securities which have been destroyed, lost or stolen and which
      have been replaced or paid as provided in Section 306 and (ii) Securities
      for whose payment money has theretofore been deposited in trust or
      segregated and held in trust by the Company and thereafter repaid to the
      Company or discharged from such trust, as provided in Section 1003) have
      been delivered to the Trustee for cancellation; or

         (B)  all such Securities not theretofore delivered to the Trustee for
      cancellation





                                      -34-
<PAGE>   45
            (i)  have become due and payable, or

           (ii)  will become due and payable at their Stated Maturity within 
         one year, or

          (iii)  are to be called for redemption within one year under
         arrangements satisfactory to the Trustee for the giving of notice of
         redemption by the Trustee in the name, and at the expense, of the
         Company,

      and the Company, in the case of (i), (ii) or (iii) above, has deposited
      or caused to be deposited with the Trustee as trust funds in trust for
      this purpose money in an amount sufficient to pay and discharge the entire
      indebtedness on such Securities not theretofore delivered to the Trustee
      for cancellation, for principal and any premium and interest to the date
      of such deposit (in the case of Securities which have become due and
      payable) or to the Stated Maturity or Redemption Date, as the case may
      be;

      (2)  the Company has paid or caused to be paid all other sums payable
   hereunder by the Company; and

      (3)  the Company has delivered to the Trustee an Officers' Certificate
   and an Opinion of Counsel, each stating that all conditions precedent herein
   provided for relating to the satisfaction and discharge of this Indenture
   have been complied with.

      Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.


SECTION 402.  Application of Trust Money.

      Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium
and interest for whose payment such money has been deposited with the Trustee.
Money deposited and held in trust pursuant to this Section 402 shall not be
subject to claims of the holders of Senior Indebtedness or of Entitled Persons
under Article Fourteen. All moneys deposited with the Trustee pursuant to
Section 401 (and held by it or the Paying Agent) for the payment of Securities
subsequently converted shall be returned to the Company upon Company Request.

SECTION 501.  Events of Default.

      "Event of Default", wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of
any court or any order, rule or regulation of any administrative or
governmental body):

      (1)  the entry by a court or governmental authority having jurisdiction
   in the premises of (A) a decree or order for relief in respect of the
   Company in an involuntary case or proceeding under any applicable Federal or
   State bankruptcy, insolvency, reorganization or other similar law or (B) a
   decree or order adjudging the Company a bankrupt or insolvent, or approving
   as properly filed a petition seeking reorganization, arrangement, adjustment
   or composition of or in respect of the Company under any applicable Federal
   or State law, or appointing a custodian, receiver, liquidator, assignee,
   trustee, sequestrator or other similar official of the Company or of any
   substantial part of its property (other than a conservator or other similar
   official in respect of a Bank), or ordering the winding up or liquidation of
   its affairs, and the continuance of any such decree or order for relief or
   any such other decree or order unstayed and in effect for a period of 60
   consecutive days; or

      (2)  the commencement by the Company of a voluntary case or proceeding
   under any applicable Federal or State bankruptcy, insolvency, reorganization
   or other similar law or of any other case or proceeding to be adjudicated a
   bankrupt or insolvent, or the consent by it to the entry of a decree or
   order for relief in respect of the Company in an involuntary case or
   proceeding under any applicable Federal or State bankruptcy, insolvency,
   reorganization or other similar law or to the commencement of any bankruptcy
   or insolvency case or proceeding against it, or the filing by it of a
   petition or answer or consent seeking reorganization or relief under any
   applicable Federal or State law, or the consent by it to the filing of such
   petition or to the appointment of or taking possession by a custodian,
   receiver, liquidator, assignee, trustee, sequestrator or other similar
   official of the Company or of any substantial part of its property (other
   than a conservator or other similar official in respect of a Bank), or the
   making by it of an assignment for the benefit of creditors, or the admission
   by it in writing of its inability to pay its debts generally as they become
   due, or the taking of corporate action by the Company in furtherance of any
   such action; or

      (3)  any other Event of Default provided with respect to Securities of
   that series.





                                      -36-
<PAGE>   47
SECTION 502.  Acceleration of Maturity; Rescission and Annulment.

      If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount of all the
Securities of that series (or, if any Securities of that series are Original
Issue Discount Securities, such portion of the principal amount of such
Securities as may be specified by the terms thereof) to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable.

      At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in
this Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if

     (1)  the Company has paid or deposited with the Trustee a sum sufficient 
   to pay

         (A)  all overdue interest on all Securities of that series,

         (B)  the principal of (and premium, if any, on) any Securities of that
      series which have become due otherwise than by such declaration of
      acceleration and any interest thereon at the rate or rates prescribed
      therefor in such Securities,

         (C)  to the extent that payment of such interest is lawful, interest
      upon overdue interest at the rate or rates prescribed therefor in such
      Securities, and

         (D)  all sums paid or advanced by the Trustee hereunder and the
      reasonable compensation, expenses, disbursements and advances of the
      Trustee, its agents and counsel;

   and

     (2)  all Defaults with respect to Securities of that series, other than
   the non-payment of the principal of Securities of that series which have
   become due solely by such declaration of acceleration, have been cured or
   waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

SECTION 503.  Collection of Indebtedness and Suits for Enforcement by Trustee.

      The Company covenants that if

      (1)  default is made in the payment of any interest on any Security when
   such interest becomes due and payable and such default continues for a
   period of 30 days, or

      (2)  default is made in the payment of  the principal of (or premium, if
   any, on) any Security at the Maturity thereof, or

      (3)  default is made in the making or satisfaction of any sinking fund
   payment or analogous obligation when the same becomes due pursuant to the
   terms of such Security,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium, interest and sinking fund obligation
and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal, premium or sinking fund obligation and on
any overdue interest, at the rate or rates prescribed therefor in such
Securities, and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

      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, may institute
a judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Security or Securities and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Company or any other obligor upon such
Securities, wherever situated.

      "Default", wherever used herein with respect to Securities of any series,
means any one of the following events (whatever the reason for such Default and
whether it shall be occasioned by the provisions of Article Fourteen or be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or governmental body);

         (A)  an Event of Default with respect to any Securities of that
      series; or

         (B)  the events referred to in subsections 503(1) through (3) above
      with respect to any Securities of that series; or

         (C)  default in the performance, or breach, of any covenant or
      warranty of the Company in this Indenture (other than a covenant or
      warranty a default in whose





                                      -38-
<PAGE>   49
   performance or whose breach is elsewhere in this Section specifically dealt
   with or which has expressly been included in this Indenture solely for the
   benefit of series of Securities other than that series), and continuance of
   such default or breach for a period of 30 days after there has been given,
   by registered or certified mail, to the Company by the Trustee or to the
   Company and the Trustee by the Holders of at least 25% in principal amount
   of the Outstanding Securities of that series a written notice specifying
   such default or breach and requiring it to be remedied and stating that such
   notice is a "Notice of Default" hereunder; or

         (D)  any other Default provided with respect to Securities of that
   series.

      If a Default with respect to Securities of any series occurs and is
continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.


SECTION 504.  Trustee May File Proofs of Claim.

      In case of any judicial proceeding relative to the Company (or any other
obligor upon the Securities), its property or its creditors, the Trustee shall
be entitled and empowered, by intervention in such proceeding or otherwise, to
take any and all actions authorized under the Trust Indenture Act in order to
have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall be authorized to collect and receive any moneys
or other property payable or deliverable on any such claims and to distribute
the same; and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee and, in
the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under Section
607.

      No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

SECTION 505.  Trustee May Enforce Claims Without Possession of Securities.

      All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto,
and any such 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 the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.


SECTION 506.  Application of Money Collected.

      Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any
premium or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

    FIRST:  To the payment of all amounts due the Trustee under Section 607; and

    SECOND: Subject to Article Fourteen, to the payment of the amounts then
   due and unpaid for principal of and any premium and interest on the
   Securities in respect of which or for the benefit of which such money has
   been collected, ratably, without preference or priority of any kind,
   according to the amounts due and payable on such Securities for principal
   and any premium and interest, respectively.


SECTION 507.  Limitation on Suits.

      No Holder of any Security of any series shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for
the appointment of a receiver or trustee, or for any other remedy hereunder,
unless

      (1)  such Holder has previously given written notice to the Trustee of a
   continuing Default with respect to the Securities of that series;

      (2)  the Holders of not less than 25% in principal amount of the
   Outstanding Securities of that series shall have made written request to the
   Trustee to institute proceedings in respect of such Default in its own name
   as Trustee hereunder;

      (3)  such Holder or Holders have offered to the Trustee reasonable
   indemnity against the costs, expenses and liabilities to be incurred in
   compliance with such request;





                                      -40-
<PAGE>   51
      (4)  the Trustee for 60 days after its receipt of such notice, request
   and offer of indemnity has failed to institute any such proceeding; and

      (5)  no direction inconsistent with such written request has been given
   to the Trustee during such 60-day period by the Holders of a majority in
   principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.


SECTION 508.  Unconditional Right of Holders to Receive Principal,
   Premium and Interest or to Convert.

      Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and, if
applicable, to convert such Security in accordance with Article Fifteen and to
institute suit for the enforcement of any such payment and right to convert,
and such rights shall not be impaired without the consent of such Holder.


SECTION 509.  Restoration of Rights and Remedies.

      If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, subject to any determination in
such proceeding, the Company, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereafter
all rights and remedies of the Trustee and the Holders shall continue as though
no such proceeding had been instituted.


SECTION 510.  Rights and Remedies Cumulative.

      Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.





                                      -41-
<PAGE>   52
The assertion or employment of any right or remedy hereunder, or otherwise,
shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.


SECTION 511.  Delay or Omission Not Waiver.

      No delay or omission of the Trustee or of any Holder of any Securities to
exercise any right or remedy accruing upon any Default shall impair any such
right or remedy or constitute a waiver of any such Default or an acquiescence
therein. Every right and remedy given by this Article or by law to the Trustee
or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be.


SECTION 512.  Control by Holders.

      The Holders of a majority in principal amount of the Outstanding
Securities of any series 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, with respect to the
Securities of such series, provided that

      (1)  such direction shall not be in conflict with any rule of law or 
    with this Indenture, and

      (2)  the Trustee may take any other action deemed proper by the Trustee
    which is not inconsistent with such direction.


SECTION 513.  Waiver of Past Defaults.

      The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default

      (1)  in the payment of the principal of or any premium or interest on any
    Security of such series, or

      (2)  in respect of a covenant or provision hereof which under Article
    Nine cannot be modified or amended without the consent of the 
    Holder of each Outstanding Security of such series affected.

      Upon any such waiver, such default shall cease to exist, and any Default
arising therefrom shall be deemed to have been cured, for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other default
or impair any right consequent thereon.

SECTION 514.  Undertaking for Costs.

      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, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit
to file an undertaking to pay the costs of such suit, and may assess costs
against any such party litigant, in the manner and to the extent provided in
the Trust Indenture Act; provided that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the
Company, by such Trustee or by a Holder or group of Holders holding in the 
aggregate more than 10% in principal amount of the Outstanding Securities of 
any series, or to any suit instituted by any Holder for the enforcement of the 
payment of the principal of (or premium, if any) or interest on any Securities 
on or after the Stated Maturity or Maturities expressed in such Securities 
(or, in the case of redemption, on or after the Redemption Date).


SECTION 515.  Waiver of Usury, Stay or Extension Laws.

      The Company covenants (to the extent that it may lawfully do so) that it
will 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 performance 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.


                                  ARTICLE SIX

                                  THE TRUSTEE


SECTION 601.  Certain Duties and Responsibilities.

      The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.
Whether or not therein expressly so provided, every provision of this Indenture
relating to the conduct or affecting the liability of or affording protection
to the Trustee shall be subject to the provisions of this Section.





                                      -43-
<PAGE>   54
SECTION 602.  Notice of Defaults.

      If a default occurs hereunder with respect to Securities of any series,
the Trustee shall give the Holders of Securities of such series notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
503(c) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the
purpose of this Section, the term "default" means any event which is, or after
notice or lapse of time or both would become, a Default with respect to
Securities of such series.

      In the absence of actual knowledge of a Responsible Officer of the
Trustee, the Trustee will not be deemed to have knowledge of any Default or
Event of Default (except the failure of the Company to make any payment when
due) unless notified thereof in writing by the Company.

SECTION 603.  Certain Rights of Trustee.

      Subject to the provisions of Section 601:

      (1)  the Trustee may rely and shall be protected in acting or refraining
   from acting upon any resolution, certificate, statement, instrument,
   opinion, report, notice, request, direction, consent, order, bond,
   debenture, note, other evidence of indebtedness or other paper or document
   believed by it to be genuine and to have been signed or presented by the
   proper party or parties;

      (2)  any request or direction of the Company mentioned herein shall be
   sufficiently evidenced by a Company Request or Company Order, and any
   resolution of the Board of Directors shall be sufficiently evidenced by a
   Board Resolution;

      (3)  whenever in the administration of this Indenture the Trustee shall
   deem it desirable that a matter be proved or established prior to taking,
   suffering or omitting any action hereunder, the Trustee (unless other
   evidence be herein specifically prescribed) may, in the absence of bad faith
   on its part, rely upon an Officers' Certificate;

      (4)  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, suffered or omitted by it
   hereunder in good faith and in reliance thereon;

      (5)  the Trustee shall be under no obligation to exercise any of the
   rights or powers vested in it by this Indenture at the request or direction
   of any of the Holders pursuant to this Indenture, unless such Holders shall
   have offered to the Trustee reasonable security or indemnity against the
   costs, expenses and liabilities which might be incurred by it in compliance
   with such request or direction;

      (6)  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, direction, consent, order,
   bond, debenture, note, other evidence of indebtedness or other paper or
   document, but the Trustee, in its discretion, may make





                                      -44-
<PAGE>   55
   such further inquiry or investigation into such facts or matters as it may
   see fit, and, if the Trustee shall determine to make such further inquiry or
   investigation, it shall be entitled to examine the books, records and
   premises of the Company, personally or by agent or attorney; and

      (7)  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 604.  Not Responsible for Recitals or Issuance of Securities.

      The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the
Company, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. The Trustee makes no representations as
to the validity or sufficiency of this Indenture or of the Securities. Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Securities or the proceeds thereof.


SECTION 605.  May Hold Securities.

      The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to
Sections 608 and 613, may otherwise deal with the Company with the same rights
it would have if it were not Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent.


SECTION 606.  Money Held in Trust.

      Money held by the Trustee in trust hereunder 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 money received by it hereunder except as
otherwise agreed with the Company.


SECTION 607.  Compensation and Reimbursement.

      The Company agrees

      (1)  to pay to the Trustee from time to time reasonable compensation for
   all services rendered by it hereunder (which compensation shall not be
   limited by any provision of law in regard to the compensation of a trustee
   of an express trust);





                                      -45-
<PAGE>   56
      (2)  except as otherwise expressly provided herein, to reimburse the
   Trustee upon its request for all reasonable expenses, disbursements and
   advances incurred or made by the Trustee in accordance with any provision of
   this Indenture (including the reasonable compensation and the expenses and
   disbursements of its agents and counsel), except any such expense,
   disbursement or advance as may be attributable to its negligence or bad
   faith; and

      (3)  to indemnify the Trustee for, and to hold it harmless against, any
   loss, liability, expense, damage or claim, including taxes, incurred without 
   negligence or bad faith on its part, arising out of or in connection with 
   the acceptance or administration of the trust or trusts hereunder, including 
   the costs and expenses of defending itself against any claim or liability in 
   connection with the exercise or performance of any of its powers or duties 
   hereunder.

      When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 501(1) or Section 501(2), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.
      
      The provisions of this Section shall survive the termination of this
Indenture and the resignation and removal of the Trustee.


SECTION 608.  Conflicting Interests.

      If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series.


SECTION 609.  Corporate Trustee Required; Eligibility.

      There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series.  Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such, and has a combined
capital and surplus of at least $50,000,000 and has its Corporate Trust Office
or agency in the Borough of Manhattan, The City of New York. If any such 
Person publishes reports of condition at least annually, pursuant to law or to 
the requirements of its supervising or examining authority, then for the 
purposes of this Section and to the extent permitted by the Trust Indenture 
Act, the combined capital and surplus of such Person shall be deemed to be its 
combined capital and surplus as set forth in its most recent report of 
condition so published. If at any time the Trustee with respect to the 
Securities of any series shall cease to be eligible in accordance with the 
provisions of this Section, it shall resign immediately in the manner and with 
the effect hereinafter specified in this Article.


SECTION 610.  Resignation and Removal; Appointment of Successor.

      No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.





                                      -46-
<PAGE>   57
      The Trustee may resign at any time with respect to the Securities of one
or more series by giving written notice thereof to the Company.

      The Trustee may be removed at any time with respect to the Securities of
any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company.

      If the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 30 days after
the giving 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 the Securities of such series.

      If at any time:

      (1)  the Trustee shall fail to comply with Section 608 after written
   request therefor by the Company or by any Holder who has been a bona fide
   Holder of a Security for at least six months, or

      (2)  the Trustee shall cease to be eligible under Section 609 and shall
   fail to resign after written request therefor by the Company or by any such
   Holder, or

      (3)  the Trustee shall become incapable of acting or shall be adjudged a
   bankrupt or insolvent or a receiver of the Trustee or of its property shall
   be appointed 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, (A) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

      If the Trustee shall resign, be removed or become incapable of acting, or
if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all
of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series) and shall comply with the
applicable requirements of Section 611. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment in accordance with the applicable requirements





                                      -47-
<PAGE>   58
of Section 611, become the successor Trustee with respect to the Securities of
such series and to that extent supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders and accepted
appointment in the manner required by Section 611, any Holder who has been a
bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

      The Company shall give notice of each resignation and each removal of the
Trustee with respect to the Securities of any series and each appointment of a
successor Trustee with respect to the Securities of any series to all Holders
of Securities of such series in the manner provided in Section 106. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.


SECTION 611.  Acceptance of Appointment by Successor.

      In case of the appointment hereunder of a successor Trustee with respect
to all Securities, every such  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.

      In case of the appointment hereunder of a successor Trustee with respect
to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1)
shall contain such provisions as shall be necessary or desirable to transfer
and confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of
that or those series to which the appointment of such successor Trustee
relates, (2) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall





                                      -48-
<PAGE>   59
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each 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 with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

      Upon request of any such 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 the
first or second preceding paragraph, as the case may be.

      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.


SECTION 612.  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 all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities 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 Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.


SECTION 613.  Preferential Collection of Claims Against Company.

      If and when the Trustee shall be or become a creditor of the Company (or
any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims
against the Company (or any such other obligor).





                                      -49-
<PAGE>   60
SECTION 614.  Appointment of Authenticating Agent.

      The Trustee may appoint an Authenticating Agent or Agents with respect to
one or more series of Securities which shall be authorized to act on behalf of
the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer, partial conversion or
partial redemption thereof or pursuant to Section 306, and Securities 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. Wherever reference is made in this Indenture to the authentication
and delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the
United States of America, any State thereof or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $50,000,000 and subject to supervision or 
examination by Federal or State authority. If such Authenticating Agent 
publishes reports of condition at least annually, pursuant to law or to the 
requirements of said supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such Authenticating Agent 
shall be deemed to be its combined capital and surplus as set forth in its 
most recent report of condition so published. If at any time an Authenticating 
Agent shall cease to be eligible in accordance with the provisions of this 
Section, such Authenticating Agent shall resign immediately in the manner and 
with the effect specified in this Section.

      Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

      An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if





                                      -50-
<PAGE>   61
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

      The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 607.

      If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

      This is one of the Securities of the series designated therein referred
to in the within-mentioned Indenture.

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the

      In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby

<PAGE>   67
this Indenture, the Trustee shall be entitled to receive, and (subject to
Section 601) shall be fully protected in relying upon, an Opinion of Counsel

                                   COVENANTS


SECTION 1001.  Payment of Principal, Premium and Interest.

      The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any
premium and interest on the Securities of that series in accordance with the
terms of the Securities and this Indenture.


SECTION 1002.  Maintenance of Office or Agency.

      The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange, where convertible Securities may be
surrendered for conversion and where notices and demands to or upon the Company
in respect of the Securities of that series and this Indenture may be served.
The Company will give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the
Company shall fail to maintain any such required office or agency or shall fail
to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

      The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in each Place of Payment for Securities of any series for such
purposes. The Company will give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other office or agency.


SECTION 1003.  Money for Securities Payments to Be Held in Trust.

      If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal and any premium and interest so
becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its
action or failure so to act.





                                      -58-
<PAGE>   69
      Whenever the Company shall have one or more Paying Agents for any series
of Securities, it will, prior to each due date of the principal of or any
premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay such amount, such sum to be held as provided by
the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

      The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (1) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

      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
by Company Order 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 trusts 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.

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Company on Company Request, or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall
thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general
circulation in the Borough of Manhattan, The City of New York, notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Company.

SECTION 1004.  Statement by Officers as to Default.

      The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers
thereof the Company is in default in the performance and observance of any of
the terms, provisions and conditions of this Indenture (without regard to any
period of grace or requirement of notice provided hereunder) and, if the
Company shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge. The Company shall deliver to
the Trustee written notice of the occurrence of any Default within ten Business
Days of the Company becoming aware thereof.


SECTION 1005.  Existence.

      Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and the rights (charter and statutory) and franchises of the Company;
provided, however, that the Company shall not be required to preserve any such
right or franchise if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and that the loss thereof is not disadvantageous in any material
respect to the Holders.


SECTION 1006.  Maintenance of Properties.

      The Company will cause all properties used or useful in the conduct of
its business or the business of any Subsidiary to be maintained and kept in
good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent the Company from
discontinuing the operation or maintenance of any of such properties if such
discontinuance is, in the judgment of the Company, desirable in the conduct of
its business or the business of any Subsidiary and not disadvantageous in any
material respect to the Holders.


SECTION 1007.  Payment of Taxes and Other Claims.

      The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary, and (2)
all lawful claims for labor, materials and supplies which, if unpaid, might by
law become a lien upon the property of the Company





                                      -60-
<PAGE>   71
or any Subsidiary; provided, however, that the Company shall not be required to
pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings and for which adequate provision is made.


SECTION 1008.  Waiver of Certain Covenants.

      Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Company may, with respect to the Securities of
any series, omit in any particular instance to comply with any term, provision
or condition set forth in any covenant provided pursuant to Section 301(18),
901(2) or 901(7) for the benefit of the Holders of such series or in any of
Sections 1005 to 1007, inclusive, if before the time for such compliance the
Holders of not less than a majority in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such term,
provision or condition, but no such waiver shall extend to or affect such term,
provision or condition except to the extent so expressly waived, and, until
such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such term, provision or condition shall
remain in full force and effect.


                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES


SECTION 1101.  Applicability of Article.

      Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for such Securities) in
accordance with this Article.


SECTION 1102.  Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution or in another manner specified as contemplated by Section
301 for such Securities. In case of any redemption at the election of the
Company of less than all the Securities of any series (including any such
redemption affecting only a single Security), the Company shall, at least 60
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of
any redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company





                                      -61-
<PAGE>   72
shall furnish the Trustee with an Officers' Certificate evidencing compliance
with such restriction.


SECTION 1103.  Selection by Trustee of Securities to Be Redeemed.

      If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed
or unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of
a portion of the principal amount of any Security of such series, provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security. If less than all the Securities of such series
and of a specified tenor are to be redeemed (unless such redemption affects
only a single Security), the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such series and specified tenor not
previously called for redemption in accordance with the preceding sentence.  If
any convertible Security selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the
Security so selected, the converted portion of such Security shall be deemed
(so far as may be) to be the portion selected for redemption.  Convertible
Securities which have been converted during a selection of Securities to be
redeemed shall be treated by the Trustee as Outstanding for the purposes of
such selection.

      The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption as aforesaid and, in case of any Securities
selected for partial redemption as aforesaid, the principal amount thereof to
be redeemed.

      The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting a series of Securities comprised of only a
single Security, whether such Security is to be redeemed in whole or in part.
In the case of any such redemption in part, the unredeemed portion of the
principal amount of the Security shall be in an authorized denomination (which
shall not be less than the minimum authorized denomination) for such Security.

      For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

SECTION 1104.  Notice of Redemption.

      Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

      All notices of redemption shall state:

      (1)  the Redemption Date,

      (2)  the Redemption Price,

      (3)  if less than all the Outstanding Securities of any series consisting
   of more than a single Security are to be redeemed, the identification (and,
   in the case of partial redemption of any such Securities, the principal
   amounts) of the particular Securities to be redeemed and, if less than all
   the entire principal amount of any series consisting of a single Security
   are to be redeemed, the portion of the principal amount of the particular
   Security to be redeemed,

      (4)  that on the Redemption Date the Redemption Price will become due and
   payable upon each such Security to be redeemed and, if applicable, that
   interest thereon will cease to accrue on and after said date,

      (5)  if the Securities to be redeemed are Convertible Securities, the
   Conversion Price, the date on which the right to convert the Securities to
   be redeemed will terminate and the place or places where such Securities may
   be surrendered for conversion,

      (6)  the CUSIP numbers, if any, of the Securities to be redeemed,

      (7)  the place or places where each such Security is to be surrendered
   for payment of the Redemption Price, and

      (8)  that the redemption is for a sinking fund, if such is the case.

      Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.


SECTION 1105.  Deposit of Redemption Price.

      Prior to any Redemption Date, the Company shall deposit with the Trustee
or with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment





                                      -63-
<PAGE>   74
Date) accrued interest on, all the Securities which are to be redeemed on that
date other than any convertible Securities called for redemption on that date
which have been converted prior to the date of such deposit.

      If any convertible Security called for redemption is converted, any money
deposited with the Trustee or with any Paying Agent or so segregated and held
in trust for the redemption of such Security shall (subject to any right of the
Holder of such Security or any Predecessor Security to receive interest as
provided in the last paragraph of Section 307) be paid to the Company upon
Company Request or, if then held by the Company, shall be discharged from such
trust.


SECTION 1106.  Securities Payable on Redemption Date.

      Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. In addition, such
Securities shall, if convertible by their terms into Common Stock, cease from
and after the date fixed for redemption (unless an earlier date shall be
specified in a Board Resolution, Officers' Certificate or executed supplemental
indenture or pursuant to which the terms of the Securities of such series were
established) to be convertible into Common Stock (unless the Company shall
default in the payment of the Redemption Price). Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be
paid by the Company at the Redemption Price, together with accrued interest to
the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 301, instalments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

      If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security. In addition, such Security shall, if convertible by its terms into
Common Stock, remain convertible into Common Stock until the principal (and
premium, if any) of such Security shall have been paid or duly provided for.


SECTION 1107.  Securities Redeemed in Part.

      Any Security which is to be redeemed only in part shall be surrendered at
a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or his
attorney duly authorized in writing),





                                      -64-
<PAGE>   75
and the Company shall execute, and the Trustee shall authenticate and deliver
to the Holder of such Security without service charge, a new Security or
Securities of the same series and of like tenor, of any authorized denomination
as requested by such Holder, in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Security so
surrendered.


                                 ARTICLE TWELVE

                                 SINKING FUNDS


SECTION 1201.  Applicability of Article.

      The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

      The minimum amount of any sinking fund payment provided for by the terms
of any Securities is herein referred to as a "mandatory sinking fund payment",
and any payment in excess of such minimum amount provided for by the terms of
such Securities is herein referred to as an "optional sinking fund payment". If
provided for by the terms of any Securities, the cash amount of any sinking
fund payment may be subject to reduction as provided in Section 1202. Each
sinking fund payment shall be applied to the redemption of Securities as
provided for by the terms of such Securities.


SECTION 1202.  Satisfaction of Sinking Fund Payments with Securities.

      The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been converted pursuant to Article Fifteen or
which have been redeemed either at the election of the Company pursuant to the
terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities or which have
otherwise been acquired by the Company, in each case in satisfaction of all or
any part of any sinking fund payment with respect to any Securities of such
series required to be made pursuant to the terms of such Securities as and to
the extent provided for by the terms of such Securities; provided that the
Securities to be so credited have not been previously so credited. The
Securities to be so credited shall be received and credited for such purpose by
the Trustee at the Redemption Price, as specified in the Securities so to be
redeemed, for redemption through operation of the sinking fund and the amount
of such sinking fund payment shall be reduced accordingly.





                                      -65-
<PAGE>   76
SECTION 1203.  Redemption of Securities for Sinking Fund.

      Not less than 60 days prior to each sinking fund payment date for any
Securities, the Company  will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant
to Section 1202 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 30 days prior to each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.


                                ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE


SECTION 1301.  Company's Option to Effect Defeasance or Covenant Defeasance.

      The Company may elect, at its option at any time, to have Section 1302 or
Section 1303 applied to any Securities or any series of Securities, as the case
may be, designated pursuant to Section 301 as being defeasible pursuant to such
Section 1302 or 1303, in accordance with any applicable requirements provided
pursuant to Section 301 and upon compliance with the conditions set forth below
in this Article. Any such election shall be evidenced by a Board Resolution or
in another manner specified as contemplated by Section 301 for such Securities.


SECTION 1302.  Defeasance and Discharge.

      Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations, and the
provisions of Article Fourteen shall cease to be effective, with respect to
such Securities as provided in this Section on and after the date the
conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Company shall
be deemed to have paid and discharged the entire indebtedness represented by
such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), subject to the following which shall survive until
otherwise terminated or discharged hereunder: (1) the rights of Holders of such
Securities to receive, solely from





                                      -66-
<PAGE>   77
the trust fund described in Section 1304 and as more fully set forth in such
Section, payments in respect of the principal of and any premium and interest
on such Securities when payments are due, (2) the Company's obligations with
respect to such Securities under Sections 304, 305, 306, 1002 and 1003, (3) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and (4)
this Article. Subject to compliance with this Article, the Company may exercise
its option (if any) to have this Section applied to any Securities
notwithstanding the prior exercise of its option (if any) to have Section 1303
applied to such Securities.


SECTION 1303.  Covenant Defeasance.

      Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, (1)
the Company shall be released from its obligations under Sections 1006 through
1007, inclusive, and any covenants provided pursuant to Section 301(18), 901(2)
or 901(7) for the benefit of the Holders of such Securities, and (2) the
occurrence of any event specified in Section 501(3) shall be deemed not to be
an Event of Default, and (3) the occurrence of any event specified in Section
503(2)(C) (with respect to any of Sections 1006 through 1007 inclusive, and any
such covenants provided pursuant to Section 301(18), 901(2) and 901(7) shall be
deemed not to be or result in a Default and (4) the provisions of Article
Fourteen shall cease to be effective, in each case with respect to such
Securities as provided in this Section on and after the date the conditions set
forth in Section 1304 are satisfied (hereinafter called "Covenant Defeasance").
For this purpose, such Covenant Defeasance means that, with respect to such
Securities, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such specified
Section or Article Fourteen, whether directly or indirectly by reason of any
reference elsewhere herein to any such Section or Article or by reason of any
reference in any such Section or Article to any other provision herein or in
any other document, but the remainder of this Indenture and such Securities
shall be unaffected thereby.


SECTION 1304.  Conditions to Defeasance or Covenant Defeasance.

      The following shall be the conditions to the application of Section 1302
or Section 1303 to any Securities or any series of Securities, as the case may
be:

      (1)  The Company shall irrevocably have deposited or caused to be
   deposited with the Trustee (or another trustee which satisfies the
   requirements contemplated by Section 609 and agrees to comply with the
   provisions of this Indenture applicable to it as if it were the Trustee
   hereunder) as trust funds in trust for the purpose of making the following
   payments, specifically pledged as security for, and dedicated solely to, the
   benefits of the Holders of such Securities, (A) in the case of Securities
   denominated in a foreign currency, money in such foreign currency or Foreign
   Government Obligations of the foreign government or governments issuing such

<PAGE>   78
   foreign currency which through the scheduled payment of principal and
   interest in respect thereof in accordance with their terms will provide, not
   later than one day before the due date of any payment, such foreign currency
   in an amount or (B) in the case of Securities denominated in U.S. dollars,
   U.S. dollars or U.S. Government Obligations which through the scheduled
   payment of principal and interest in respect thereof in accordance with
   their terms will provide, not later than one day before the due date of any
   payment, U.S. dollars in an amount, or (C) a combination of money and U.S.
   Government Obligations or Foreign Government Obligations (as applicable), in
   each case sufficient, in the opinion of a nationally recognized firm of
   independent public accountants expressed in a written certification thereof
   delivered to the Trustee, to pay and discharge, and which shall be applied
   by the Trustee (or any such other qualifying trustee) to pay and discharge,
   the principal of and any premium and interest on such Securities on the
   respective Stated Maturities, in accordance with the terms of this Indenture
   and such Securities. As used herein, "U.S. Government Obligation" means (x)
   any security which is (i) a direct obligation of the United States of
   America for the payment of which the full faith and credit of the United
   States of America is pledged or (ii) an obligation of a Person controlled or
   supervised by and acting as an agency or instrumentality of the United
   States of America the payment of which is unconditionally guaranteed as a
   full faith and credit obligation by the United States of America, which, in
   either case (i) or (ii), is not callable or redeemable at the option of the
   issuer thereof, and (y) any depositary receipt issued by a bank (as defined
   in Section 3(a)(2) of the Securities Act) as custodian with respect to any
   U.S. Government Obligation which is specified in Clause (x) above and held
   by such bank for the account of the holder of such depositary receipt, or
   with respect to any specific payment of principal of or interest on any U.S.
   Government Obligation which is so specified and held, provided that (except
   as required by law) such custodian is not authorized to make any deduction
   from the amount payable to the holder of such depositary receipt from any
   amount received by the custodian in respect of the U.S. Government
   Obligation or the specific payment of principal or interest evidenced by
   such depositary receipt.  As used herein, "Foreign Government Obligation"
   means any security denominated in a Foreign Currency which is (i) a direct
   obligation of a foreign government or governments for the payment of which
   the full faith and credit of such foreign government or governments is
   pledged or (ii) an obligation of a Person controlled or supervised by and
   acting as an agency or instrumentality of such foreign government or
   governments the payment of which is unconditionally guaranteed as a full
   faith and credit obligation by such foreign government, which, in either
   case (i) or (ii) is not callable or redeemable at the option of the issuer
   thereof.

      (2)  In the event of an election to have Section 1302 apply to any
   Securities or any series of Securities, as the case may be, the Company
   shall have delivered to the Trustee an Opinion of Counsel stating that
   (A)(x) the Company has received from, or there has been published by, the
   Internal Revenue Service a ruling or (y) since the date of this instrument,
   there has been a change in the applicable Federal income tax law, in either
   case (x) or (y) to the effect that, and based thereon such opinion shall
   confirm that, the Holders of such Securities will not recognize gain or loss
   for Federal income tax purposes as a result of the deposit, Defeasance and
   discharge to be effected with





                                      -68-
<PAGE>   79
   respect to such Securities and will be subject to Federal income tax on the
   same amount, in the same manner and at the same times as would be the case
   if such deposit, Defeasance and discharge were not to occur and (B) if
   Securities of such series Securities are then listed on the New York Stock
   Exchange, to the effect that the Securities of such series will not be
   delisted as a result of such election.

      (3)  In the event of an election to have Section 1303 apply to any
   Securities or any series of Securities, as the case may be, the Company
   shall have delivered to the Trustee an Opinion of Counsel to the effect that
   the Holders of such Securities will not recognize gain or loss for Federal
   income tax purposes as a result of the deposit and Covenant Defeasance to be
   effected with respect to such Securities and will be subject to Federal
   income tax on the same amount, in the same manner and at the same times as
   would be the case if such deposit and Covenant Defeasance were not to occur.

      (4)  The Company shall have delivered to the Trustee an Officer's
   Certificate to the effect that neither such Securities nor any other
   Securities of the same series, if then listed on any securities exchange,
   will be delisted as a result of such deposit.


      (5)  No event which is, or after notice or lapse of time or both would
   become, a Default with respect to such Securities or any other Securities
   shall have occurred and be continuing at the time of such deposit or, with
   regard to any such event specified in Sections 501(1) and (2), at any time
   on or prior to the 90th day after the date of such deposit or, if longer,
   ending on the day following the expiration of the longest preference period
   applicable to the Company under Federal or State Law in respect of such
   deposit (it being understood that this condition shall not be deemed
   satisfied until after the expiration of such period).

      (6)  Such Defeasance or Covenant Defeasance shall not cause the Trustee
   to have a conflicting interest within the meaning of the Trust Indenture Act
   (assuming all Securities are in default within the meaning of such Act).

      (7)  At the time of such deposit, (A) no default in the payment of all or
   a portion of principal of (or premium, if any) or interest on any Senior
   Indebtedness shall have occurred and be continuing, and no event of default
   with respect to any Senior Indebtedness shall have occurred and be
   continuing and shall have resulted in such Senior Indebtedness becoming or
   being declared due and payable prior to the date on which it would otherwise
   have become due and payable and (B) such Defeasance or Covenant Defeasance
   shall not result in a breach or violation of, or constitute a default under,
   any other agreement or instrument to which the Company is a party or by
   which it is bound.

      (8)  Such Defeasance or Covenant Defeasance shall not result in the trust
   arising from such deposit constituting an investment company within the
   meaning of the Investment Company Act unless such trust shall be registered
   under such Act or exempt from registration thereunder.





                                      -69-
<PAGE>   80
      (9)   The Company shall have delivered to the Trustee an Officer's
   Certificate and an Opinion of Counsel, each stating that all conditions
   precedent with respect to such Defeasance or Covenant Defeasance have been
   complied with including any conditions imposed in connection therewith
   pursuant to Section 301.


SECTION 1305.  Deposited Money and U.S. Government Obligations to Be
   Held in Trust; Miscellaneous Provisions.

        Subject to the provisions of the last paragraph of Section 1003, all
money, U.S. Government Obligations and Foreign Government Obligations
(including the proceeds thereof) deposited with the Trustee or other qualifying
trustee (solely for purposes of this Section and Section 1306, the Trustee and
any such other trustee are referred to collectively as the "Trustee") pursuant
to Section 1304 in respect of any Securities shall be held in trust and applied
by the Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any such Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal and any premium and interest, but money so held
in trust need not be segregated from other funds except to the extent required
by law. Money, U.S. Government Obligations and Foreign Government Obligations
so held in trust shall not be subject to the provisions of Article Fourteen.

        The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations or
Foreign Government Obligations deposited pursuant to Section 1304 or the
principal and interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of Outstanding
Securities.

        Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations or Foreign Government Obligations held by
it as provided in Section 1304 with respect to any Securities which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect the Defeasance or Covenant Defeasance, as the case may be, with respect
to such Securities.


SECTION 1306.  Reinstatement.

      If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to





                                      -70-
<PAGE>   81
apply all money held in trust pursuant to Section 1305 with respect to such
Securities in accordance with this Article; provided, however, that if the
Company makes any payment of principal of or any premium or interest on any
such Security following such reinstatement of its obligations, the Company
shall be subrogated to the rights (if any) of the Holders of such Securities to
receive such payment from the money so held in trust.

                                ARTICLE FOURTEEN

                          SUBORDINATION OF SECURITIES


SECTION 1401.  Securities Subordinate to Senior Indebtedness.

      The Company covenants and agrees, and each Holder of a Security, by his
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article and except to the extent
otherwise provided pursuant to Section 301(22), the indebtedness represented by
the Securities and the payment of the principal of (and premium, if any) and
interest on each and all of the Securities are hereby expressly made
subordinate and subject in right of payment to the prior payment in full of all
Senior Indebtedness and, to the extent set forth in this Article, all Other
Financial Obligations.


SECTION 1402.  Payment Over of Proceeds Upon Dissolution, Etc.

      In the event of (a) any insolvency or bankruptcy case or proceeding, or
any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relative to the Company or to its
creditors, as such, or to its assets, or (b) any liquidation, dissolution or
other winding up of the Company, whether voluntary or involuntary and whether
or not involving insolvency or bankruptcy, or (c) any assignment for the
benefit of creditors or any other marshalling of assets and liabilities of the
Company, then and in any such event the holders of Senior Indebtedness shall be
entitled to receive payment in full of all amounts due or to become due on or
in respect of all Senior Indebtedness, or provision shall be made for such
payment in money or money's worth, before the Holders of the Securities are
entitled to receive any payment on account of principal of (or premium, if any)
or interest on the Securities, and to that end the holders of Senior
Indebtedness shall be entitled to receive, for application to the payment
thereof, any payment or distribution of any kind or character, whether in cash,
property or securities, including any such payment or distribution which may be
payable or deliverable by reason of the payment of any other indebtedness of
the Company being subordinated to the payment of the Securities, which may be
payable or deliverable in respect of the Securities in any such case,
proceeding, dissolution, liquidation or other winding up or event.

      In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, including any such payment or
distribution which may be payable or deliverable by reason of the payment of
any other indebtedness of the Company being subordinated to the payment of the
Securities, before all Senior Indebtedness is paid in full or payment thereof
provided for, and if such fact shall, at or prior to the time of such payment
or distribution, have been made known to the Trustee or, as the case may be,
such Holder, then and in such event such payment or distribution shall be paid
over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee, agent or other Person making payment or
distribution of assets of the Company for application to the payment of all
Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior
Indebtedness in full, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

      For purposes of this Article only, 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 which are
subordinated in right of payment to all Senior Indebtedness which may at the
time be outstanding to substantially the same extent as, or to a greater extent
than, the Securities are so subordinated as provided in this Article.  The
consolidation of the Company with, or the merger of the Company into, another
Person or the liquidation or dissolution of the Company following the
conveyance or transfer of its properties and assets substantially as an
entirety to another Person upon the terms and conditions set forth in Article
Eight shall not be deemed a dissolution, winding up, liquidation,
reorganization, assignment for the benefit of creditors or marshalling of
assets and liabilities of the Company for the purposes of this Section if the
Person formed by such consolidation or into which the Company is merged or the
Person which acquires by conveyance or transfer such properties and assets
substantially as an entirety, as the case may be, shall, as a part of such
consolidation, merger, conveyance or transfer, comply with the conditions set
forth in Article Eight.


SECTION 1403.  Prior Payment to Senior Indebtedness Upon Acceleration of
    Securities.

      In the event that any Securities are declared due and payable before
their Stated Maturity, then and in such event the holders of Senior
Indebtedness shall be entitled to receive payment in full of all amounts due or
to become due on or in respect of all Senior Indebtedness or provision shall be
made for such payment in money or money's worth, before the Holders of the
Securities are entitled to receive any payment (including any payment which may
be payable by reason of the payment of any other indebtedness of the Company
being subordinated to the payment of the Securities) by the Company on account
of the principal of (or premium, if any) or interest on the Securities or on
account of the purchase or other acquisition of Securities; provided, however,
that nothing in this Section shall prevent the satisfaction of any sinking fund
payment in accordance





                                      -72-
<PAGE>   83
with Article Twelve by delivering and crediting pursuant to Section 1202
Securities which have been acquired (upon redemption or otherwise) prior to
such declaration of acceleration.

      In the event that, notwithstanding the foregoing, the Company shall make
any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to
the time of such payment, have been made known to the Trustee or, as the case
may be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

      The provisions of this Section shall not apply to any payment with
respect to which Section 1402 would be applicable.


SECTION 1404.  No Payment When Senior Indebtedness in Default.

      (a) In the event and during the continuation of any default in the
payment of principal of (or premium, if any) or interest on any Senior
Indebtedness beyond any applicable grace period with respect thereto, or in the
event that any event of default with respect to any Senior Indebtedness shall
have occurred and be continuing permitting the holders of such Senior
Indebtedness (or a trustee on behalf of the holders thereof) to declare such
Senior Indebtedness due and payable prior to the date on which it would
otherwise have become due and payable, unless and until such event of default
shall have been cured or waived or shall have ceased to exist and such
acceleration shall have been rescinded or annulled, or (b) in the event any
judicial proceeding shall be pending with respect to any such default in
payment or event of default, then no payment (including any payment which may
be payable by reason of the payment of any other indebtedness of the Company
being subordinated to the payment of the Securities) shall be made by the
Company on account of principal of (or premium, if any) or interest on the
Securities or on account of the purchase or other acquisition of Securities;
provided, however, that nothing in this Section shall prevent the satisfaction
of any sinking fund payment in accordance with Article Twelve by delivering and
crediting pursuant to Section 1202 Securities which have been acquired (upon
redemption or otherwise) prior to such default in payment or event of default.

      In the event that, notwithstanding the foregoing, the Company shall make
any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to
the time of such payment, have been made known to the Trustee or, as the case
may be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

      The provisions of this Section shall not apply to any payment with
respect to which Section 1402 would be applicable.





                                      -73-
<PAGE>   84
SECTION 1405.  Payment Permitted in Certain Situations.

      Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent (a) the Company, at any time except during
the pendency of any case, proceeding, dissolution, liquidation or other winding
up, assignment for the benefit of creditors or other marshalling of assets and
liabilities of the Company referred to in Section 1402 or under the conditions
described in Section 1403 or 1404, from making payments at any time of
principal of (and premium, if any) or interest on the Securities or (b) the
application by the Trustee of any money deposited with it hereunder to the
payment of or on account of the principal of (and premium, if any) or interest
on the Securities of any series or the retention of such payment by the Holder,
if, at the time of such application by the Trustee, it did not have actual
knowledge that such payment would have been prohibited by the provisions of
this Article.


SECTION 1406.  Subrogation to Rights of Holders of Senior Indebtedness.

      Subject to the payment in full of all Senior Indebtedness, the Holders of
the Securities shall be subrogated to the extent of the payments or
distributions made to the holders of such Senior Indebtedness pursuant to the
provisions of this Article (equally and ratably with the holders of all
Existing Subordinated Indebtedness and all indebtedness of the Company which by
its express terms is subordinated to indebtedness of the Company to
substantially the same extent as the Securities or the Existing Subordinated
Indebtedness are subordinated and is entitled to like rights of subrogation) to
the rights of the holders of such Senior Indebtedness to receive payments and
distributions of cash, property and securities applicable to the Senior
Indebtedness until the principal of (and premium, if any) and interest on the
Securities shall be paid in full.  For purposes of such subrogation, no
payments or distributions to the holders of the Senior Indebtedness of any
cash, property or securities to which the Holders of the Securities or the
Trustee would be entitled except for the provisions of this Article, and no
payments over pursuant to the provisions of this Article to the holders of
Senior Indebtedness by Holders of the Securities or the Trustee, shall, as
among the Company, its creditors other than holders of Senior Indebtedness and
the Holders of the Securities, be deemed to be a payment or distribution by the
Company to or on account of the Senior Indebtedness.


SECTION 1407.  Provisions Solely to Define Relative Rights.

      The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Indebtedness (and, in the case of Section
1415, Entitled Persons in respect of Other Financial Obligations) on the other
hand.  Nothing contained in this Article or elsewhere in this Indenture or in
the Securities is intended to or shall (a) impair, as among the Company, its
creditors other than holders of Senior Indebtedness and other than Entitled
Persons in respect of Other Financial Obligations and the Holders of the
Securities, the obligation of the Company, which is absolute and unconditional
(and





                                      -74-
<PAGE>   85
which, subject to the rights under this Article of the holders of Senior
Indebtedness and Entitled Persons in respect of Other Financial Obligations, is
intended to rank equally with all other general obligations of the Company), to
pay to the Holders of the Securities the principal of (and premium, if any) and
interest on the Securities as and when the same shall become due and payable in
accordance with their terms; or (b) affect the relative rights against the
Company of the Holders of the Securities and creditors of the Company other
than the holders of Senior Indebtedness and Entitled Persons in respect of
Other Financial Obligations; or (c) prevent the Trustee or the Holder of any
Security from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if any, under this
Article of the holders of Senior Indebtedness and under Section 1415 of
Entitled Persons in respect of Other Financial Obligations, to receive cash,
property and securities otherwise payable or deliverable to the Trustee or such
Holder.


SECTION 1408.  Trustee to Effectuate Subordination.

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


SECTION 1409.  No Waiver of Subordination Provisions.

      No right of any present or future holder of any Senior Indebtedness 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
non-compliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

      Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness (and Entitled Persons in respect of Other
Financial Obligations) may, at any time and from time to time, without the
consent of or notice to the Trustee or the Holders of the Securities, without
incurring responsibility to the Holders of the Securities and without impairing
or releasing the subordination provided in this Article or the obligations
hereunder of the Holders of the Securities to the holders of Senior
Indebtedness and Entitled Persons, in respect of Other Financial Obligations,
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, Senior
Indebtedness or Other Financial Obligations, or otherwise amend or supplement
in any manner Senior Indebtedness or Other Financial Obligations or any
instrument evidencing the same or any agreement under which Senior Indebtedness
is or Other Financial Obligations are outstanding; (ii) sell, exchange, release
or otherwise deal with any property pledged, mortgaged or otherwise securing
Senior Indebtedness or Other Financial Obligations; (iii) release any





                                      -75-
<PAGE>   86
Person liable in any manner for the collection of Senior Indebtedness or Other
Financial Obligations; and (iv) exercise or refrain from exercising any rights
against the Company and any other Person.


SECTION 1410.  Notice to Trustee.

      The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by
the Trustee in respect of the Securities.  Notwithstanding the provisions of
this Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Indebtedness or from any trustee therefor or from
any Entitled Persons in respect of Other Financial Obligations; and, prior to
the receipt of any such written notice, the Trustee, subject to the provisions
of Section 601, shall be entitled in all respects to assume that no such facts
exist.

      Subject to the provisions of Section 601, the Trustee shall be entitled
to rely on the delivery to it of a written notice by a Person representing
himself to be a holder of Senior Indebtedness (or a trustee therefor) or an
Entitled Person in respect of Other Financial Obligations to establish that
such notice has been given by a holder of Senior Indebtedness (or a trustee
therefor) or an Entitled Person in respect of Other Financial Obligations.  In
the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness or an Entitled Person in respect of Other Financial Obligations to
participate in any payment or distribution pursuant to this Article, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Indebtedness or Other
Financial Obligations held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article, and if such evidence
is not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.


SECTION 1411.  Reliance on Judicial Order or Certificate of Liquidating Agent.

      Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee, subject to the provisions of Section 601, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Senior





                                      -76-
<PAGE>   87
Indebtedness and other indebtedness of the Company and the Entitled Persons in
respect of Other Financial Obligations, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article.


SECTION 1412.  Trustee Not Fiduciary for Holders of Senior Indebtedness or
   Entitled Persons.

      The Trustee shall not be deemed to owe any fiduciary duty to the holders
of Senior Indebtedness or Entitled Persons in respect of Other Financial
Obligations and shall not be liable to any such holders or creditors if it
shall in good faith mistakenly pay over or distribute to Holders of Securities
or to the Company or to any other Person cash, property or securities to which
any holders of Senior Indebtedness or Entitled Persons in respect of Other
Financial Obligations shall be entitled by virtue of this Article or otherwise.


SECTION 1413.  Rights of Trustee as Holder of Senior Indebtedness or Entitled
   Person; Preservation of Trustee's Rights.

      The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Indebtedness which
may at any time be held by it and with respect to any Other Financial
Obligations owed to the Trustee as an Entitled Person, to the same extent as
any other holder of Senior Indebtedness or Entitled Person in respect of Other
Financial Obligations, as the case may be, and nothing in this Indenture shall
deprive the Trustee of any of its rights as such holder or Entitled Person.

      Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 607.


SECTION 1414.  Article Applicable to Paying Agents.

      In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article in addition to or in place of the Trustee; provided,
however, that Section 1413 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.


SECTION 1415.  Securities to Rank Pari Passu with Existing Subordinated
   Indebtedness.

      (a) Subject to the provisions of this Section and to any provisions
established or determined with respect to Securities of any series pursuant to
Section 301, the Securities





                                      -77-
<PAGE>   88
shall rank pari passu in right of payment with all other Securities and the
Existing Subordinated Indebtedness.

      (b) Upon the occurrence of any of the events specified in clauses (a),
(b) and (c) of the first paragraph of Section 1402, the provisions of that
Section and the corresponding provisions of each indenture or other instrument
or document establishing or governing the terms of any Existing Subordinated
Indebtedness shall be given effect on a pro rata basis to determine the amount
of cash, property or securities which may be payable or deliverable as between
the holders of Senior Indebtedness, on the one hand, and the Holders of
Securities and holders of Existing Subordinated Indebtedness, on the other
hand.

      (c) If, after giving effect to the provisions of Section 1402, Section
1406 and the respective corresponding provisions of each indenture or other
instrument or document establishing or governing the terms of any Senior
Indebtedness on such pro rata basis, any amount of cash, property or securities
shall be available for payment or distribution in respect of the Securities
("Excess Proceeds"), and any Entitled Persons in respect of Other Financial
Obligations shall not have received payment in full of all amounts due or to
become due on or in respect of such Other Financial Obligations (and provision
shall not have been made for such payment in money or money's worth), then such
Excess Proceeds shall first be applied (ratably with any amount of cash,
property or securities available for payment or distribution in respect of any
other indebtedness of the Company that by its express terms provides for the
payment over of amounts corresponding to Excess Proceeds to Entitled Persons in
respect of Other Financial Obligations) to pay or provide for the payment of
the Other Financial Obligations remaining unpaid, to the extent necessary to
pay all Other Financial Obligations in full, after giving effect to any
concurrent payment or distribution to or for Entitled Persons in respect of
Other Financial Obligations.  Any Excess Proceeds remaining after the payment
(or provision for payment) in full of all Other Financial Obligations shall be
available for payment or distribution in respect of the Securities.

      (d) In the event that, notwithstanding the foregoing provisions of
subsection (c) of this Section, after the occurrence of any of the events
specified in clauses (a), (b) and (c) of the first paragraph of Section 1402,
the Trustee or Holder of any Security shall have received any payment or
distribution of assets of the Company of any kind or character, whether in
cash, property or securities, before Senior Indebtedness and all Other
Financial Obligations are paid in full or payment thereof duly provided for,
and if such fact shall, at or prior to the time of such payment or
distribution, have been made known to the Trustee or, as the case may be, such
Holder, then and in such event, subject to any obligation that the Trustee or
such Holder may have pursuant to Section 1402, such payment or distribution
shall be paid over or delivered forthwith to the trustee in bankruptcy,
receiver, liquidating trustee, custodian, assignee, agent or other Person
making payment or distribution of assets of the Company for payment in
accordance with subsection (c).





                                      -78-
<PAGE>   89
      (e) Subject to the payment in full of all Other Financial Obligations,
the Holders of the Securities shall be subrogated (equally and ratably with the
holders of all indebtedness of the Company that by its express terms provides
for the payment over of amounts corresponding to Excess Proceeds to Entitled
Persons in respect of Other Financial Obligations and is entitled to like
rights of subrogation) to the extent of the payments or distributions made to
Entitled Persons in respect of Other Financial Obligations pursuant to
subsection (c) or (d) of this Section to the rights of the Entitled Persons in
respect of Other Financial Obligations to receive payments and distributions of
cash, property and securities applicable to the Other Financial Obligations
until the principal of (and premium, if any) and interest on the Securities
shall be paid in full.  For purposes of such subrogation, no payments or
distributions to Entitled Persons in respect of Other Financial Obligations of
any cash, property or securities to which Holders of the Securities or the
Trustee would be entitled except for the provisions of this Section, and no
payments over pursuant to the provisions of this Section to Entitled Persons in
respect of Other Financial Obligations by Holders of Securities or the Trustee,
shall, as among the Company, its creditors other than Entitled Persons in
respect of Other Financial Obligations and the Holders of Securities be deemed
to be a payment or distribution by the Company to or on account of the Other
Financial Obligations.

      (f) The provisions of subsections (c), (d) and (e) of this Section are
and are intended solely for the purpose of defining the relative rights of the
Holders of the Securities, on the one hand, and the Entitled Persons in respect
of Other Financial Obligations, on the other hand, after giving effect to the
rights of the holders of Senior Indebtedness, as provided in this Article.
Nothing contained in subsections (c), (d) and (e) of this Section is intended
to or shall affect the relative rights against the Company of the Holders of
the Securities and creditors of the Company other than Entitled Persons in
respect of Other Financial Obligations.

SECTION  1416.  Certain Conversions Deemed Payment.

   For purposes of this Article only, (1) the issuance and delivery of junior
securities upon conversion of Securities in accordance with Article Fifteen
shall not be deemed to constitute a payment or distribution on account of the
purchase or other acquisition of Securities, and (2) the payment, issuance or
delivery of cash, property or securities (other than junior securities) upon
conversion of a security shall be deemed to constitute payment on account of
the principal of such Securities.  For purposes of this Section, the term
"junior securities" means (a) shares of any stock of any class of the Company
and (b) securities of the Company which are subordinated in right of payment to
all Senior Indebtedness which may be outstanding at the time of issuance or
delivery of such securities to substantially the same extent as, or to a
greater extent than, the Securities are so subordinated as provided in this
Article.  Nothing contained in this Article or elsewhere in this Indenture or
in the Securities is intended to or shall impair, as among the Company, its
creditors other than holders of Senior Indebtedness and the Holders of the
Securities, the right, which is absolute and unconditional, of the Holder of
any convertible Security to convert such Security in accordance with Article
Fifteen.

                                ARTICLE FIFTEEN

                            CONVERSION OF SECURITIES

SECTION 1501. Applicability of Article.

      The Company may elect, at its option at any time, to have Section 1502
applied to any Securities or any series of Securities, as the case may be,
designated pursuant to Section 301 as being convertible into Common Stock of
the Company pursuant to such Section 1502, in accordance with any applicable
requirements provided pursuant to Section 301 and upon compliance with the
conditions set forth below in this Article.  Any such election shall be
evidenced by a Board Resolution or in another manner specified as contemplated
by Section 301 for such Securities.

SECTION 1502. Conversion Privilege and Conversion Price.

      Subject to and upon compliance with the provisions of this Article, at
the option of the Holder thereof, any Security or any portion of the principal
amount thereof which is an integral multiple of the authorized denomination
thereof may be converted at the principal amount thereof, or of such portion
thereof, into fully paid and nonassessable shares (calculated as to each
conversion to the nearest 1/100 of a share) of Common Stock of the Company, at
the conversion price for Securities of such series, determined as hereinafter
provided, in effect at the time of conversion.  Such conversion right shall
commence at the opening of business on the Initial Conversion Date and expire
at the close of business on the Final Conversion Date.  In case a Security or
portion thereof is called for redemption, such conversion right in respect of
the Security or portion so called shall expire at the close of business on the
Redemption Date, unless the Company defaults in making the payment due upon
redemption.

      The price at which shares of Common Stock shall be delivered upon
conversion of Securities of a series (herein called the "conversion price" for
Securities of such series) shall be initially the Initial Conversion Price for
Securities of such series per share of Common Stock.  The conversion price
shall be adjusted in certain instances as provided in paragraphs (1), (2), (3),
(4) and (7) of Section 1504.

SECTION 1503. Exercise of Conversion Privilege.

      In order to exercise the conversion privilege, the Holder of any Security
to be converted shall surrender such Security, duly endorsed or assigned to the
Company or in blank, at any office or agency of the Company maintained for that
purpose pursuant to Section 1002, accompanied by written notice to the Company
at such office or agency that the Holder elects to convert such Security or, if
less than the entire principal amount thereof is to be converted, the portion
thereof to be converted.  Securities surrendered for conversion during the
period from the close of business on any Regular Record Date next preceding any
Interest Payment Date to the opening of business on such Interest Payment Date
shall (except in the case of Securities or portions thereof which have been





                                      -80-
<PAGE>   91
called for redemption on a Redemption Date within such period) be accompanied
by payment in funds acceptable to the Company of an amount equal to the
interest payable on such Interest Payment Date on the principal amount of
Securities being surrendered for conversion.  Except as provided in the
preceding sentence and subject to the last paragraph of Section 307, no payment
or adjustment shall be made upon any conversion on account of any interest
accrued on the Securities surrendered for conversion or on account of any
dividends on the Common Stock issued upon conversion.

      Securities shall be deemed to have been converted immediately prior to
the close of business on the day of surrender of such Securities for conversion
in accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to receive the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such
time.  As promptly as practicable on or after the conversion date, the Company
shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in Section 1504.

      In the case of any Security of a series which is converted in part only,
upon such conversion the Company shall execute and the Trustee shall
authenticate and deliver to the Holder thereof, at the expense of the Company,
a new Security or Securities of such series of authorized denominations in
aggregate principal amount equal to the unconverted portion of the principal
amount of such Security.

SECTION 1504. Fractions of Shares.

      No fractional shares of Common Stock shall be issued upon conversion of
Securities.  If more than one Security of a series shall be surrendered for
conversion at one time by the same Holder, the number of full shares which
shall be issuable upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Securities of such series (or specified
portions thereof) so surrendered.  Instead of any fractional share of Common
Stock which would otherwise be issuable upon conversion of any Security or
Securities (or specified portion thereof), the Company shall pay a cash
adjustment in respect of such fraction in an amount equal (computed to the
nearest cent) to the same fraction of the market price per share of Common
Stock (as determined by the Board of Directors or in any manner prescribed by
the Board of Directors) at the close of business on the day of conversion.

SECTION 1505. Adjustment of Conversion Price.

      (1)  In case at any time after the date of establishment of the Initial
Conversion Price with respect to Securities of a series the Company shall pay
or make a dividend or other distribution in shares of Common Stock on any class
of capital stock of the Company, the conversion price in effect at the opening
of business on the day following the date fixed for the determination of
stockholders entitled to receive such dividend or





                                      -81-
<PAGE>   92
other distribution shall be reduced by multiplying such conversion price by a
fraction of which the numerator shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such determination
and the denominator shall be the sum of such number of shares and the total
number of shares constituting such dividend or other distribution, such
reduction to become effective immediately after the opening of business on the
day following the date fixed for such determination.  For the purposes of this
paragraph, the number of shares of Common Stock at any time outstanding shall
not include shares held in the treasury of the Company.  The Company will not
pay any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company.

      (2)  In case at any time after the date of establishment of the Initial
Conversion Price with respect to Securities of a series the Company shall issue
rights or warrants to all holders of its Common Stock entitling them to
subscribe for or purchase shares of Common Stock at a price per share less than
the current market price per share (determined as provided in paragraph (6) of
this Section) of the Common Stock on the date fixed for the determination of
stockholders entitled to receive such rights or warrants, the conversion price
in effect at the opening of business on the day following the date fixed for
such determination shall be reduced by multiplying such conversion price by a
fraction of which the numerator shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such determination
plus the number of shares of Common Stock which the aggregate of the offering
price of the total number of shares of Common Stock so offered for subscription
or purchase would purchase at such current market price and the denominator
shall be the number of shares of Common Stock outstanding at the close of
business on the dated fixed for such determination plus the number of shares of
Common Stock so offered for subscription or purchase, such reduction to become
effective immediately after the opening of business on the day following the
date fixed for such determination.  For the purposes of this paragraph (2), the
number of shares of Common Stock at any time outstanding shall not include
shares held in the treasury of the Company.  The Company will not issue any
rights or warrants in respect of shares of Common Stock held in the treasury of
the Company.

      (3)  In case at any time after the date of establishment of the Initial
Conversion Price with respect to Securities of a series outstanding shares of
Common Stock shall be subdivided into a greater number of shares of Common
Stock, the conversion price in effect at the opening of business on the day
following the day upon which such subdivision becomes effective shall be
proportionately reduced, and, conversely, in case outstanding shares of Common
Stock shall each be combined into a smaller number of shares of Common Stock,
the conversion price in effect at the opening of business on the day following
the day upon which such combination becomes effective shall be proportionately
increased, such reduction or increase, as the case may be, to become effective
immediately after the opening of business on the day following the day upon
which such subdivision or combination becomes effective.

<PAGE>   93
      (4)  In case at any time after the date of establishment of the Initial
Conversion Price with respect to Securities of a series the Company shall, by
dividend or otherwise, distribute to all holders of its Common Stock evidences
of its indebtedness or assets (including securities, but excluding any rights
or warrants referred to in paragraph (2) of this Section, any dividend or
distribution paid in cash out of the retained earnings of the Company and any
dividend or distribution referred to in paragraph (1) of this Section), the
conversion price shall be adjusted so that the same shall equal the price
determined by multiplying the conversion price in effect immediately prior to
the close of business on the date fixed for the determination of stockholders
entitled to receive such distribution by a fraction of which the numerator
shall be the current market price per share (determined as provided in
paragraph (6) of this Section) of the Common Stock on the date fixed for such
determination less the then fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution filed with the Trustee) of the portion of assets or evidences of
indebtedness so distributed applicable to one share of Common Stock and the
denominator shall be such current market price per share of the Common Stock,
such adjustment to become effective immediately prior to the opening of
business on the day following the date fixed for the determination of
stockholders entitled to receive such distribution.

      (5)  The reclassification of Common Stock into securities other than
Common Stock (other than any reclassification upon a consolidation or merger to
which Section 1502 applies) shall be deemed to involve (a) a distribution of
such securities other than Common Stock to all holders of Common Stock (and the
effective date of such reclassification shall be deemed to be "the date fixed
for the determination of stockholders entitled to receive such distribution"
and "the date fixed for such determination" within the meaning of paragraph (4)
of this Section), and (b) a subdivision or combination, as the case may be, of
the number of shares of Common Stock outstanding immediately prior to such
reclassification into the number of shares of Common Stock outstanding
immediately thereafter (and the effective date of such reclassification shall
be deemed to be "the day upon which such subdivision becomes effective" or "the
day upon which such combination becomes effective", as the case may be, and
"the day upon which such subdivision or combination becomes effective" within
the meaning of paragraph (3) of this Section).

      (6)  For the purpose of any computation under paragraphs (2) and (4) of
this Section, the current market price per share of Common Stock on any date
shall be deemed to be the average of the daily closing prices for the 30
consecutive Business Days selected by the Company commencing not less than 30
nor more than 45 Business Days before the day in question.  The closing price
for each day shall be the last reported sales price regular way or, in case no
such reported sale takes place on such day, the average of the reported closing
bid and asked prices regular way, in either case on the New York Stock Exchange
or, if the Common Stock is not listed or admitted to trading on such Exchange,
on the principal national securities exchange on which the Common Stock is
listed or admitted to trading or, if not listed or admitted to trading on any
national securities exchange, on the National Association of Securities Dealers
Automated Quotations National Market System or, if the Common Stock is not
listed or admitted to





                                      -83-
<PAGE>   94
trading on any national securities exchange or quoted on such National Market
System, the average of the closing bid and asked prices in the over-the-counter
market as furnished by any New York Stock Exchange member firm selected from
time to time by the Company for that purpose.

      (7)  No adjustment in the conversion price shall be required unless such
adjustment would require an increase or decrease of at least 1% in such price;
provided, however, that any adjustment which by reason of this paragraph (7) is
not required to be made shall be carried forward and taken into account in any
subsequent adjustment; and provided, further that all such adjustments shall be
made no later than the third anniversary of the earliest date on which an
adjustment would have been made but for this paragraph (7) and all calculations
under this paragraph (7) shall be made to the nearest cent.

      (8)  The Company may make such reductions in the conversion price, in
addition to those required by paragraphs (1), (2), (3) and (4) of this Section,
as it considers to be advisable in order that any event treated for Federal
income tax purposes as a dividend of stock or stock rights shall not be taxable
to the recipients.

SECTION 1506.  Notice of Adjustments of Conversion Price.

      Whenever the conversion price is adjusted as herein provided:

         (a)  the Company shall compute the adjusted conversion price in
      accordance with Section 1506 and shall prepare a certificate signed by
      the Treasurer of the Company setting forth the adjusted conversion price
      and showing in reasonable detail the facts upon which such adjustment is
      based, and such certificate shall forthwith be filed at each office or
      agency maintained for the purpose of conversion of Securities pursuant to
      Section 1002; and

         (b)  a notice stating that the conversion price has been adjusted and
      setting forth the adjusted conversion price shall forthwith be required,
      and as soon as practicable after it is required, such notice shall be
      mailed by the Company to all Holders at their respective last addresses
      as they shall appear in the Security Register.

SECTION 1507.  Notice of Certain Corporate Action.

      In case at any time after 20 Business Days preceding the Initial
Conversion Date:

         (a)  the Company shall declare a dividend (or any other distribution)
      on its Common Stock payable otherwise than in cash out of its retained
      earnings; or

         (b)  the Company shall authorize the granting to the holders of its
      Common Stock of rights or warrants to subscribe for or purchase any
      shares of capital stock of any class or of any other rights; or





                                      -84-
<PAGE>   95
         (c)  of any reclassification of the Common Stock of the Company (other
      than a subdivision or combination of its outstanding shares of Common
      Stock), or of any consolidation or merger to which the Company is a party
      and for which approval of any stockholders of the Company is required, or
      of the sale or transfer of all or substantially all of the assets of the
      Company; or

         (d)  of the voluntary or involuntary dissolution, liquidation or
      winding up of the Company;

then the Company shall cause to be filed at each office or agency maintained
for the purpose of conversion of Securities pursuant to Section 1002, and shall
cause to be mailed to all Holders at their respective last addresses as they
shall appear in the Security Register, at least 20 days (or 10 days in any case
specified in Clause (a) or (b) above) prior to the applicable record or
effective date hereinafter specified, a notice stating (x) the date on which a
record is to be taken for the purpose of such dividend, distribution, rights or
warrants, or, if a record is not to be taken, the date as of which the holders
of Common Stock of record to be entitled to such dividend, distribution, rights
or warrants are to be determined, or (y) the date on which such
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up is expected to become effective, and the date as of
which it is expected that holders of Common Stock of record shall be entitled
to exchange their shares of Common Stock for securities, cash or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding up.

SECTION 1508.  Company to Reserve Common Stock.

      The Company shall at all times reserve and keep available, free from
pre-emptive rights, out of its authorized but unissued Common Stock, for the
purpose of effecting the conversion of Securities, the full number of shares of
Common Stock then issuable upon the conversion of all outstanding Securities.

SECTION 1509.  Taxes on Conversions.

      The Company will pay any and all taxes that may be payable in respect of
the issue or delivery of shares of Common Stock on conversion of Securities
pursuant hereto.  The Company shall not, however, be required to pay any tax
which may be payable in respect of any transfer involved in the issue and
delivery of shares of Common Stock in a name other than that of the Holder of
the Security or Securities to be converted, and no such issue or delivery shall
be made unless and until the Person requesting such issue has paid to the
Company the amount of any such tax, or has established to the satisfaction of
the Company that such tax has been paid.

SECTION 1510.  Covenant as to Common Stock.

      The Company covenants that all shares of Common Stock which may be issued
upon conversion of Securities will upon issue be fully paid and nonassessable
and, except





                                      -85-
<PAGE>   96
as provided in Section 1509, the Company will pay all taxes, liens and charges
with respect to the issue thereof.

      The Company covenants that if any shares of Common Stock to be provided
for the purpose of conversion of Securities hereunder require registration with
or approval of any governmental authority under any Federal or State law before
such shares may be validly delivered upon conversion, the Company will in good
faith and as expeditiously as possible endeavor to secure such registration or
approval, as the case may be.

SECTION 1511.  Cancellation of Converted Securities.

      All Securities delivered for conversion shall be delivered to the Trustee
to be cancelled by or at the direction of the Trustee, which shall dispose of
the same as provided in Section 309.

SECTION 1512.  Provisions in Case of Consolidation, Merger or Sale of Assets.

      In case of any consolidation of the Company with, or merger of the
Company into, any other Person, any merger of another Person into the Company
(other than a merger which does not result in any reclassification, conversion,
exchange or cancellation of outstanding shares of Common Stock of the Company)
or any sale or transfer of all or substantially all of the assets of the
Company, the Person formed by such consolidation or resulting from such merger
or which acquires such assets, as the case may be, shall execute and deliver to
the Trustee a supplemental indenture providing that the Holder of each Security
then outstanding shall have the right thereafter, during the period such
Security shall be convertible as specified in Section 1502, to convert such
Security only into the kind and amount of securities, cash and other property
receivable upon such consolidation, merger, sale or transfer by a holder of the
number of shares of Common Stock of the Company into which such Security might
have been converted immediately prior to such consolidation, merger, sale or
transfer, assuming such holder of Common Stock of the Company (i) is not a
Person with which the Company consolidated or into which the Company merged or
which merged into the Company or to which such sale or transfer was made, as
the case may be ("constituent Person"), or an Affiliate of a constituent Person
and (ii) failed to exercise his rights of election, if any, as to the kind or
amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer (provided that if the kind or amount of
securities, cash and other property receivable upon such consolidation, merger,
sale or transfer is not the same for each share of Common Stock of the Company
held immediately prior to such consolidation, merger, sale or transfer by
others than a constituent Person or an Affiliate thereof and in respect of
which such rights of election shall not have been exercised ("non-electing
share"), then for the purpose of this Section the kind and amount of
securities, cash and other property receivable upon such consolidation, merger,
sale or transfer by each non-electing share shall be deemed to be the kind and
amount so receivable per share by a plurality of the non-electing shares), and
assuming, if such consolidation, merger, sale or transfer is prior to the
Initial Conversion Date, that the Securities were convertible at the time of
such consolidation, merger, sale or transfer at the initial





                                      -86-
<PAGE>   97
conversion price specified in Section 1502 as adjusted from the date of
establishment of the Initial Conversion Price with respect to Securities of a
series to such time pursuant to paragraphs (1), (2), (3), (4) and (7) of
Section 1505.  Such supplemental indenture shall provide for adjustments which,
for events subsequent to the effective date of such supplemental indenture,
shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Article.  The above provisions of this Section shall similarly
apply to successive consolidations, mergers, sales or transfers.

SECTION 1513.  Responsibility of Trustee.

      The Trustee shall not at any time be under any duty or responsibility to
any Holder of a Security to make or cause to be made any adjustment of the
conversion price, or to determine whether any facts exist which may require any
such adjustment, or with respect to the nature or extent of any such adjustment
when made, or with respect to any method employed, or herein or in any
supplemental indenture provided to be employed, in making the same.  The
Trustee shall not be accountable with respect to the validity or value (or the
kind or amount) of any shares of Common Stock or of any securities or property
which may at any time be issued or delivered upon conversion of any Security;
and the Trustee makes no representation with respect thereto.  The Trustee
shall not be responsible for any failure of the Company to issue, transfer or
deliver any shares of Common Stock or stock certificates or other securities or
property upon surrender of any Security for the purpose of conversion or to
comply with any of the covenants of the Company contained in this Article
Fifteen.

                               _________________
      This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts

         First Tennessee Reports Record Earnings For Third Quarter 1995

          MEMPHIS, TENN.-- First Tennessee National Corporation (First
Tennessee) reported record earnings of $43.8 million for third quarter of 1995,
an increase of 17 percent from the $37.6 million for the third quarter of 
1994.  Earnings per share for the third quarter increased to $1.30 compared with
$1.11 for the third quarter of 1994.  Return on average assets for the quarter
ended September 30, 1995, improved to 1.50 percent and return on average equity
improved to 21.32 percent.  These financial ratios compare with return on
average assets of 1.42 percent and return on average equity of 19.41 percent
for the quarter ended September 30, 1994.

          For the first nine months, net income totaled $119.2 million, a 4
percent increase from $114.2 million for the first nine months of 1994.
Earnings per share for the nine month period were $3.51 in 1995 compared to
$3.34 in 1994.  For the nine month period, return on average assets was 1.43
percent and return on average equity was 19.84 percent, compared with 1.45
percent and 20.21 percent, respectively, for the same period in 1994.

          Ralph Horn, president and chief executive officer, said, "We are
pleased to report another quarter of record earnings.  In addition, we achieved
an unprecedented return on assets of 1.50 percent and a return on equity in
excess of 21 percent.  These results were
<PAGE>   2

attained with double digit loan growth in all loan categories and improving
results in the majority of our business lines."


Noninterest income

          Total noninterest income (excluding securities gains in both
periods), which accounted for 56 percent of total revenues in the quarter, was
$126.4 million, a 20 percent increase from the previous year.  All categories
of noninterest income, excluding securities gains, increased from the 1994
third quarter levels.  Mortgage banking noninterest income, as a result of
increased originations and the benefit of new accounting rules related to
originated servicing rights, increased 29 percent.  Noninterest income in the
bond division rose 16 percent, reflecting increased volumes over 1994.
Noninterest income from trust services increased 25 percent, demonstrating
continued growth in managed assets and the benefits of an accounting change
earlier in 1995; bank card income, which includes credit card and merchant
processing fees, increased 17 percent solely due to a $1.5 million increase in
merchant processing fees from an expansion in our customer base; and income
from deposit transactions and cash management increased 8 percent.  During the
third quarter of 1995, First Tennessee's mortgage banking entities originated
$2.5 billion compared with $1.4 billion in 1994.  Year-to-date mortgage loan
originations in 1995 were $5.0 billion compared to $5.8 billion in 1994.  At
September 30, 1995, the combined servicing portfolio was $15.4 billion compared
with $14.5 billion at September 30, 1994.

          Year to-date, total noninterest income, excluding securities gains in
both periods, increased 5 percent from 1994 levels to $354.8 million.  For the
nine month period,


                                     -more-
<PAGE>   3

noninterest income in mortgage banking was relatively flat while noninterest
income in the bond division decreased 4 percent, primarily due to unusually
favorable environments experienced by both business units in the first quarter
of 1994.  Additionally, bank card income increased 21 percent, trust service
income increased 31 percent, and income from deposit transactions and cash
management increased 12 percent over the same nine month period in 1994.


Net Interest Earnings

          For the third quarter of 1995, net interest income, on a fully
taxable equivalent basis, was $99.8 million, which was relatively flat compared
with the previous year.  Average earning assets, net of unearned income,
increased 11 percent from the previous year and included an 18 percent increase
in average loans, net of unearned income, with a 2 percent decrease in
investment securities.  The growth in earning assets was supported by a 32
percent increase in purchased funds and a 5 percent increase in
interest-bearing core deposits.  The net interest margin decreased 44 basis
points to 3.85 percent from the third quarter of 1994, but has remained
relatively stable during 1995.  The 6 basis point decrease in the margin from
the second quarter to the third quarter reflects the impact on the margin of
increased activities in the bond division and in the mortgage warehouse, which
were partially mitigated by improvement in the "core" (bank) margin.

          For the first nine months of 1995, net interest income, on a fully
taxable equivalent basis, decreased $12.6 million, or 4 percent, from the same
period last year.

Noninterest operating expense

         Total noninterest operating expenses increased 4 percent from the
third quarter of 1994.  Employee compensation, incentives and benefits, the
largest component of noninterest operating expense, increased 9 percent.  The
effect of the lower FDIC premiums (from $.23 to $.04 per $100 of deposits) and
the refund from the FDIC reduced deposit insurance expense $4.4 million in the
third quarter.  In addition, current legislative discussion associated with the
undercapitalized Savings Association Insurance Fund (SAIF) could potentially
result in a one-time assessment on First Tennessee's SAIF-insured deposits.
The timing of this assessment may be as early as the fourth quarter of 1995 and
the maximum pre-tax cost to First Tennessee is estimated to be approximately
$6.5 million, which would potentially offset the benefit of the FDIC premium
reduction realized in the last half of 1995.

         For the first nine months of 1995, total noninterest operating
expenses have declined 7 percent, with an 8 percent decrease in employee
compensation, incentives and benefits.  The other expense category declined 17
percent, reflecting the cost of establishing the charitable foundation in 1994.


Income Taxes

         The effective tax rate increased from 32.0 percent in the third
quarter of 1994 to 35.6 percent in the third quarter of 1995, primarily due to
a $1.9 million tax reduction in the third quarter of 1994 for the elimination
of a deferred tax valuation allowance related to the acquisition of SNMC
Management Corporation, parent company of Sunbelt National Mortgage Company.
