<PAGE>   15
               In any case where several matters are required to be certified
by, or covered by an opinion of, any specified Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

               Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion
of, or 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 such officer's
certificate or opinion are 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 information with respect to such factual matters is in
the possession of the Company, unless such counsel knows, or in the exercise of

               Whenever, subsequent to the receipt by the Trustee of any Board
Resolution, Officer's Certificate, Opinion of Counsel or other document or
instrument, a clerical, typographical or other inadvertent or unintentional
error or omission shall be discovered therein, a new document or instrument may
be substituted therefor in corrected form with the same force and effect as if
originally filed in the corrected form and, irrespective of the date or dates
of the actual execution and/or delivery thereof, such substitute document or
instrument shall be deemed to have been executed and/or delivered as of the
date or dates required with respect to the document or instrument for which it
is substituted. Anything in this Indenture to the contrary notwithstanding, if
any such corrective document or instrument indicates that action has been taken
by or at the request of the Company which could not have been taken had the
original document or instrument not contained such error or omission, the
action so taken shall not be invalidated or otherwise rendered ineffective but
shall be and remain in full force and effect, except to the extent that such
action was a result of willful misconduct or bad faith. Without limiting the
generality of the foregoing, any Securities issued under the authority of such
defective document or instrument shall nevertheless be the valid obligations of
the Company entitled to the benefits of this Indenture equally and ratably with
all other Outstanding Securities, except as aforesaid.

consent, election, waiver or other action provided by this Indenture to be

<PAGE>   16
such Holders in person or by an agent duly appointed in writing or,
alternatively, may be embodied in and evidenced by the record of Holders voting
in favor thereof, either in person or by proxies duly appointed in writing, at
any meeting of Holders duly called and held in accordance with the provisions
of Article Thirteen, or a combination of such instruments and any such record.
Except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments or record or both are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments and any such record (and the action embodied therein
and evidenced thereby) are herein sometimes referred to as the "Act" of the
Holders signing such instrument or instruments and so voting at any such
meeting. Proof of execution of any such instrument or of a writing appointing
any such agent, or of the holding by any Person of a Security, shall be
sufficient for any purpose of this Indenture and (subject to Section 901)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section. The record of any meeting of Holders shall be proved
in the manner provided in Section 1306.

               (b)  The Act 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, or may be
proved in any other manner which the Trustee and the Company deem sufficient.
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.

               (c)   The principal amount (except as otherwise contemplated in
clause (y) of the proviso to the definition of Outstanding) and serial numbers
of Securities held by any Person, and the date of holding the same, shall be
proved by the Security Register.

               (d)  Any request, demand, authorization, direction, notice,
consent, election, waiver or other Act of a Holder 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.

               (e)  Until such time as written instruments shall have been
delivered to the Trustee with respect to the requisite percentage of principal
amount of Securities for the action contemplated by such instruments, any such
instrument executed and delivered by or on behalf of a Holder may be revoked
with respect to any or all of such Securities by written notice by such Holder
or any subsequent Holder, proven in the manner in which such instrument was
proven.

               (f)  Securities of any series, or any Tranche thereof,
authenticated and delivered after any Act of Holders may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any
action taken by such Act of Holders. If the Company shall so determine, new
Securities of any series, or any Tranche thereof, so modified as to conform, in

Company and authenticated and delivered by the Trustee in exchange for
Outstanding Securities of such series or Tranche.

               (g)  If the Company shall solicit from Holders any request,
demand, authorization, direction, notice, consent, waiver or other Act, the
Company may, at its option, by Board Resolution, fix in advance a record date
for the determination of Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Company
shall have no obligation to do so. If such a record date is fixed, such
request, demand, authorization, direction, notice, consent, waiver or other Act
may be given before or after such record date, but only the Holders of record
at the close of business on the record date shall be deemed to be Holders for
the purposes of determining whether Holders of the requisite proportion of the
Outstanding Securities have authorized or agreed or consented to such request,
demand, authorization, direction, notice, consent, waiver or other Act, and for
that purpose the Outstanding Securities shall be computed as of the record
date.

SECTION 105. NOTICES, ETC. TO TRUSTEE AND COMPANY.

Trustee by any Holder or by the Company, or the Company by the Trustee or by

SECTION 106. NOTICE TO HOLDERS OF SECURITIES; WAIVER.

               Except as otherwise expressly provided herein, where this
Indenture provides for notice to Holders of any event, such notice shall be
sufficiently given, and shall be deemed given, to Holders if in writing and
mailed, first-class postage prepaid, to each Holder affected by such event, at
the address of such Holder as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, prescribed for
the giving of such notice.

               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 to
Holders by mail, then such notification as shall be made with the approval of
the Trustee shall constitute a sufficient notification for every purpose
hereunder. 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.

               Any notice required by this Indenture may be waived in writing
by the Person entitled to receive such notice, either before or after the event
otherwise to be specified therein, 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.


SECTION 107. CONFLICT WITH TRUST INDENTURE ACT.

               If any provision of this Indenture limits, qualifies or
conflicts with another provision hereof which is required or deemed to be
included in this Indenture by, or is otherwise governed by, any of the
provisions of the Trust Indenture Act, such other provision shall control; and
if any provision hereof otherwise conflicts with the Trust Indenture Act, the
Trust Indenture Act shall control.


SECTION 108. EFFECT OF HEADINGS AND TABLE OF CONTENTS.

               The Article and Section headings in this Indenture 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

SECTION 110. SEPARABILITY CLAUSE.

               In case any provision in this Indenture or 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 the Securities, express or implied,
shall give to any Person, other than the parties hereto, their successors
hereunder, the Holders, and so long as there is Senior Indebtedness
outstanding, the holders thereof, 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

SECTION 113. LEGAL HOLIDAYS.

               In any case where any Interest Payment Date, Redemption Date or
Stated Maturity of any Security 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 in Securities of any series, or any Tranche
thereof, or in the Board Resolution or Officer's Certificate which establishes
the terms of the Securities of such series or Tranche, which specifically
states that such provision shall apply in lieu of this Section) payment of
interest or principal and premium, if any, 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, except that if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day in each case with the same force and effect as if made
on the Interest Payment Date or Redemption Date, or at the Stated Maturity,
and, if such payment is made or duly provided for on such Business Day, no
interest shall accrue on the amount so payable for the period from and after
such Interest Payment Date, Redemption Date or Stated Maturity, as the case may
be, to such Business Day.

shall be executed on behalf of the Company by an Authorized Officer and may
have the corporate seal of the Company affixed thereto or reproduced thereon

officers on the Securities may be manual or facsimile.

               Securities bearing the manual or facsimile signatures of
individuals who were at the time of execution Authorized Officers of the
Company shall bind the Company, notwithstanding that such individuals or any of
them have ceased to hold such offices prior to the authentication and delivery

     a Board Resolution, or in an Officer's Certificate pursuant to a
     supplemental indenture or Board Resolution, all as contemplated by
     Sections 201 and 301, either (i) establishing such terms or (ii) in the
     case of Securities of a series subject to a Periodic Offering, specifying
     procedures, acceptable to the Trustee, by which such terms are to be
     established (which procedures may provide, to the extent acceptable to the
     Trustee, for authentication and delivery pursuant to oral or electronic
     instructions from the Company or any agent or agents thereof, which oral
     instructions are to be promptly confirmed electronically or in writing),
     in either case in accordance with the instrument or instruments delivered
     pursuant to clause (a) above;

               (c)  the Securities of such series, executed on behalf of the
     Company by an Authorized Officer;

               conformity with the provisions of this Indenture;

                      (ii)     the terms of such Securities have been duly
               authorized by the Company and have been established in
               conformity with the provisions of this Indenture; and

                      (iii)    such Securities, when authenticated and
               delivered by the Trustee and issued and delivered by the Company
               in the manner and subject to any conditions specified in such
               Opinion of Counsel, will have been duly issued under this
               Indenture and will constitute valid and legally binding
               obligations of the Company, entitled to the benefits provided by
               this Indenture, and enforceable in accordance with their terms,
               subject, as to enforcement, to laws relating to or affecting
               generally the enforcement of creditors' rights, including,
               without limitation, bankruptcy and insolvency laws and to
               general principles of equity (regardless of whether such
               enforceability is considered in a proceeding in equity or at
               law);

     provided, however, that, with respect to Securities of a series subject to
a Periodic Offering, the Trustee shall be entitled to receive such Opinion of
Counsel only once at or prior to the time of the first authentication of such
Securities (provided that such Opinion of Counsel addresses the authentication
and delivery of all Securities of such series) and that in lieu of the opinions
described in clauses (ii) and (iii) above Counsel may opine that:

               (x)  when the terms of such Securities shall have been
     established pursuant to a Company Order or Orders or pursuant to such
     procedures (acceptable to the Trustee) as may be specified from time to
     time by a Company Order or Orders, all as contemplated by and in
     accordance with the instrument or instruments delivered pursuant to clause
     (a) above, such





                                       19

     terms will have been duly authorized by the Company and will have been
     established in conformity with the provisions of this Indenture; and

               (y)  such Securities, when authenticated and delivered by the
     Trustee in accordance with this Indenture and the Company Order or Orders
     or specified procedures referred to in paragraph (x) above and issued and
     delivered by the Company in the manner and subject to any conditions
     specified in such Opinion of Counsel, will have been duly issued under
     this Indenture and will constitute valid and legally binding obligations
     of the Company, entitled to the benefits provided by the Indenture, and
     enforceable in accordance with their terms, subject, as to enforcement, to
     laws relating to or affecting generally the enforcement of creditors'
     rights, including, without limitation, bankruptcy and insolvency laws and
     to general principles of equity (regardless of whether such enforceability
     is considered in a proceeding in equity or at law).

               With respect to Securities of a series subject to a Periodic
Offering, the Trustee may conclusively rely, as to the authorization by the
Company of any of such Securities, the form and terms thereof and the legality,
validity, binding effect and enforceability thereof, upon the Opinion of
Counsel and other documents delivered pursuant to Sections 201 and 301 and this
Section, as applicable, at or prior to the time of the first authentication of
Securities of such series unless and until such opinion or other documents have
been superseded or revoked or expire by their terms. In connection with the
authentication and delivery of Securities of a series subject to a Periodic
Offering, the Trustee shall be entitled to assume that the Company's
instructions to authenticate and deliver such Securities do not violate any
rules, regulations or orders of any Governmental Authority having jurisdiction
over the Company.

               If the form or terms of the Securities of any series have been
established by or pursuant to a Board Resolution or an Officer's Certificate as
permitted by Sections 201 or 301, the Trustee shall not be required to
authenticate such Securities if the issuance of such Securities pursuant to
this Indenture will affect the Trustee's own rights, duties or immunities under
the Securities and this Indenture in a manner which is not reasonably
acceptable to the Trustee.

               Unless otherwise specified as contemplated by Section 301 with
respect to any series of Securities, or any Tranche thereof, each Security
shall be dated the date of its authentication.

               Unless otherwise specified as contemplated by Section 301 with
respect to any series of Securities, or any Tranche thereof, 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 or its agent 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 hereunder and is entitled to
the benefits of this Indenture. Notwithstanding the foregoing, if any Security
shall have been authenticated and delivered hereunder to the Company, or any
Person acting on its behalf, but shall never have been issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 309 together with a written statement
(which need not comply with Section 102 and need not be accompanied by an
Opinion of Counsel) stating that





                                       20
<PAGE>   27
such Security has never been issued and sold by the Company, 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 hereof.

SECTION 304. TEMPORARY SECURITIES.

               Pending the preparation of definitive Securities of any series,
or any Tranche thereof, 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, 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;
provided, however, that temporary Securities need not recite specific
redemption, sinking fund, conversion or exchange provisions.

               Unless otherwise specified as contemplated by Section 301 with
respect to the Securities of any series, or any Tranche thereof, after the
preparation of definitive Securities of such series or Tranche, the temporary
Securities of such series or Tranche shall be exchangeable, without charge to
the Holder thereof, for definitive Securities of such series or Tranche upon
surrender of such temporary Securities at the office or agency of the Company
maintained pursuant to Section 602 in a Place of Payment for such Securities.
Upon such surrender of temporary Securities, the Company shall, except as
aforesaid, execute and the Trustee shall authenticate and deliver in exchange
therefor definitive Securities of the same series and Tranche, of authorized
denominations and of like tenor and aggregate principal amount.

               Until exchanged in full as hereinabove provided, temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and Tranche and of like
tenor authenticated and delivered hereunder.

SECTION 305.  REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

               The Company shall cause to be kept in each office designated
pursuant to Section 602, with respect to the Securities of each series or any
Tranche thereof, a register (all registers kept in accordance with this Section
being 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 of such series or Tranche and the registration
of transfer thereof. The Company shall designate one Person to maintain the
Security Register for the Securities of each series on a consolidated basis,
and such Person is referred to herein, with respect to such series, as the
"Security Registrar".  Anything herein to the contrary notwithstanding, the
Company may designate one or more of its offices as an office in which a
register with respect to the Securities of one or more series, or any Tranche
or Tranches thereof, shall be maintained, and the Company may designate itself
the Security Registrar with respect to one or more of such series. The Security
Register shall be open for inspection by the Trustee and the Company at all
reasonable times.





                                       21
<PAGE>   28
               Except as otherwise specified as contemplated by Section 301
with respect to the Securities of any series, or any Tranche thereof, upon
surrender for registration of transfer of any Security of such series or
Tranche at the office or agency of the Company maintained pursuant to Section
602 in a Place of Payment for such series or Tranche, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
series and Tranche, of authorized denominations and of like tenor and aggregate
principal amount.

               Except as otherwise specified as contemplated by Section 301
with respect to the Securities of any series, or any Tranche thereof, any
Security of such series or Tranche may be exchanged at the option of the Holder
for one or more new Securities of the same series and Tranche, of authorized
denominations and of like tenor and aggregate principal amount, upon surrender
of the Securities to be exchanged at any 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 delivered upon any registration of transfer or
exchange of Securities shall be 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, the Trustee or
the Security Registrar) be duly endorsed or shall be accompanied by a written
instrument of transfer in form satisfactory to the Company, the Trustee or the
Security Registrar, as the case may be, duly executed by the Holder thereof or
his attorney duly authorized in writing.

               Unless otherwise specified as contemplated by Section 301 with
respect to Securities of any series, or any Tranche thereof, 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, 406 or 1206 not involving any transfer.

               The Company shall not be required to execute or to provide for
the registration of transfer of or the exchange of (a) Securities of any
series, or any Tranche thereof, during a period of 15 days immediately
preceding the date notice is to be given identifying the serial numbers of the
Securities of such series or Tranche called for redemption or (b) any Security
so selected for redemption in whole or in part, except the unredeemed portion
of any Security being redeemed in part.





                                       22
<PAGE>   29
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 (a)
evidence to their satisfaction of the ownership of and the destruction, loss or
theft of any Security and (b) such security or indemnity as may be reasonably
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
is held by a Person purporting to be the owner of such Security, 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
Tranche, and of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

               Notwithstanding the foregoing, 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.

               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
reasonable 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 other than
the Holder of such new Security, and any such new Security shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all
other Securities of such 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.

               Unless otherwise specified as contemplated by Section 301 with
respect to the Securities of any series, or any Tranche thereof, 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.





                                       23
<PAGE>   30
               Subject to Section 312, 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 related 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 (a) or (b) below:

               (a)  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
date (herein called 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 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 promptly cause notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor to be mailed, first-class postage
prepaid, to each Holder of Securities of such series at the address of such
Holder as it appears in the Security Register, 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.

               (b)  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 and Section
305, 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.

SECTION 308. PERSONS DEEMED OWNERS.

               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
absolute owner of such Security for the purpose of receiving payment of
principal of and premium, if any, and (subject to Sections





                                       24
<PAGE>   31
305 and 307) interest, if any, 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.

SECTION 309. CANCELLATION BY SECURITY REGISTRAR.

               All Securities surrendered for payment, redemption, registration
of transfer or exchange shall, if surrendered to any Person other than the
Security Registrar, be delivered to the Security Registrar and, if not
theretofore canceled, shall be promptly canceled by the Security Registrar. The
Company may at any time deliver to the Security Registrar for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever or which the Company shall not have
issued and sold, and all Securities so delivered shall be promptly canceled by
the Security Registrar. No Securities shall be authenticated in lieu of or in
exchange for any Securities canceled as provided in this Section, except as
expressly permitted by this Indenture. All canceled Securities held by the
Security Registrar shall be disposed of in accordance with a Company Order
delivered to the Security Registrar and the Trustee, and the Security Registrar
shall promptly deliver a certificate of disposition to the Trustee and the
Company unless, by a Company Order, similarly delivered, the Company shall
direct that canceled Securities be returned to it. The Security Registrar shall
promptly deliver evidence of any cancellation of a Security in accordance with
this Section 309 to the Trustee and the Company.

SECTION 310. COMPUTATION OF INTEREST.

               Except as otherwise specified as contemplated by Section 301 for
Securities of any series, or any Tranche thereof, interest on the Securities of
each series shall be computed on the basis of a 360-day year consisting of
twelve 30-day months and on the basis of the actual number of days elapsed
within any month in relation to the deemed 30 days of such month.

SECTION 311. PAYMENT TO BE IN PROPER CURRENCY.

               In the case of the Securities of any series, or any Tranche
thereof, denominated in any currency other than Dollars or in a composite
currency (the "Required Currency"), except as otherwise specified with respect
to such Securities as contemplated by Section 301, the obligation of the
Company to make any payment of the principal thereof, or the premium or
interest thereon, shall not be discharged or satisfied by any tender by the
Company, or recovery by the Trustee, in any currency other than the Required
Currency, except to the extent that such tender or recovery shall result in the
Trustee timely holding the full amount of the Required Currency then due and
payable. If any such tender or recovery is in a currency other than the
Required Currency, the Trustee may take such actions as it considers
appropriate to exchange such currency for the Required Currency. The costs and
risks of any such exchange, including without limitation the risks of delay and
exchange rate fluctuation, shall be borne by the Company, the Company shall
remain fully liable for any shortfall or delinquency in the full amount of
Required Currency then due and payable, and in no circumstances shall the
Trustee be liable therefor except in the case of its negligence or willful
misconduct.





                                       25
<PAGE>   32
SECTION 312. EXTENSION OF INTEREST PAYMENT.

               The Company shall have the right at any time, so long as the
Company is not in default in the payment of interest on the Securities of any
series hereunder, to extend interest payment periods on all Securities of one
or more series, or Tranches thereof, if so specified as contemplated by Section
301 with respect to such Securities and upon such terms as may be specified as
contemplated by Section 301 with respect to such Securities.

                                  ARTICLE FOUR

                            REDEMPTION OF SECURITIES

SECTION 401. APPLICABILITY OF ARTICLE.

               Securities of any series, or any Tranche thereof, 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 Securities of such series or Tranche) in accordance with this Article.

SECTION 402. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

               The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution or an Officer's Certificate. The Company shall,
at least 45 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee in
writing of such Redemption Date and of the principal amount of such Securities
to be redeemed. In the case of any redemption of Securities (a) prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture or (b) pursuant to an election of the
Company which is subject to a condition specified in the terms of such
Securities, the Company shall furnish the Trustee with an Officer's Certificate
evidencing compliance with such restriction or condition.

SECTION 403. SELECTION OF SECURITIES TO BE REDEEMED.

               If less than all the Securities of any series, or any Tranche
thereof, are to be redeemed, the particular Securities to be redeemed shall be
selected by the Security Registrar from the Outstanding Securities of such
series or Tranche not previously called for redemption, by such method as shall
be provided for any particular series, or, in the absence of any such
provision, by such method of random selection as the Security Registrar shall
deem fair and appropriate and which may, in any case, provide for the selection
for redemption of portions (equal to the minimum authorized denomination for
Securities of such series or Tranche or any integral multiple thereof) of the
principal amount of Securities of such series or Tranche of a denomination
larger than the minimum authorized denomination for Securities of such series
or Tranche; provided, however, that if, as indicated in an Officer's
Certificate, the Company shall have offered to purchase all or any principal
amount of the Securities then Outstanding of any series, or any Tranche
thereof, and less than all of such Securities as to which such offer was





                                       26
<PAGE>   33
made shall have been tendered to the Company for such purchase, the Security
Registrar, if so directed by Company Order, shall select for redemption all or
any principal amount of such Securities which have not been so tendered.

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

               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 404. NOTICE OF REDEMPTION.

               Notice of redemption shall be given in the manner provided in
Section 106 to the Holders of the Securities to be redeemed not less than 30
nor more than 60 days prior to the Redemption Date.

               All notices of redemption shall state:

               (a)  the Redemption Date,

               (b)  the Redemption Price,

               (c)  if less than all the Securities of any series or Tranche
are to be redeemed, the identification of the particular Securities to be
redeemed and the portion of the principal amount of any Security to be redeemed
in part,

               (d)  that on the Redemption Date the Redemption Price, together
with accrued interest, if any, to the Redemption Date, 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,

               (e)  the place or places where such Securities are to be
surrendered for payment of the Redemption Price and accrued interest, if any,
unless it shall have been specified as contemplated by Section 301 with respect
to such Securities that such surrender shall not be required,

               (f)  that the redemption is for a sinking or other fund, if such
is the case, and

               (g)  such other matters as the Company shall deem desirable or
appropriate.

               Unless otherwise specified with respect to any Securities in
accordance with Section 301, with respect to any notice of redemption of
Securities at the election of the Company, unless, upon the giving of such
notice, such Securities shall be deemed to have been





                                       27
<PAGE>   34
paid in accordance with Section 701, such notice may state that such redemption
shall be conditional upon the receipt by the Paying Agent or Agents for such
Securities, on or prior to the date fixed for such redemption, of money
sufficient to pay the principal of and premium, if any, and interest, if any,
on such Securities and that if such money shall not have been so received such
notice shall be of no force or effect and the Company shall not be required to
redeem such Securities. In the event that such notice of redemption contains
such a condition and such money is not so received, the redemption shall not be
made and within a reasonable time thereafter notice shall be given, in the
manner in which the notice of redemption was given, that such money was not so
received and such redemption was not required to be made, and the Paying Agent
or Agents for the Securities otherwise to have been redeemed shall promptly
return to the Holders thereof any of such Securities which had been surrendered
for payment upon such redemption.

               Notice of redemption of Securities to be redeemed at the
election of the Company, and any notice of non-satisfaction of a condition for
redemption as aforesaid, shall be given by the Company or, at the Company's
request, by the Security Registrar in the name and at the expense of the
Company. Notice of mandatory redemption of Securities shall be given by the
Security Registrar in the name and at the expense of the Company.

SECTION 405. SECURITIES PAYABLE ON REDEMPTION DATE.

               Notice of redemption having been given as aforesaid, and the
conditions, if any, set forth in such notice having been satisfied, the
Securities or portions thereof 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, in the case of an unconditional notice of redemption,
the Company shall default in the payment of the Redemption Price and accrued
interest, if any) such Securities or portions thereof, if interest-bearing,
shall cease to bear interest. Upon surrender of any such Security for
redemption in accordance with such notice, such Security or portion thereof
shall be paid by the Company at the Redemption Price, together with accrued
interest, if any, to the Redemption Date; provided, however, that no such
surrender shall be a condition to such payment if so specified as contemplated
by Section 301 with respect to such Security; and provided, further, that
except as otherwise specified as contemplated by Section 301 with respect to
such Security, any installment of interest on any Security the Stated Maturity
of which installment is on or prior to the Redemption Date shall be payable to
the Holder of such Security, or one or more Predecessor Securities, registered
as such at the close of business on the related Regular Record Date according
to the terms of such Security and subject to the provisions of Section 307.

SECTION 406. SECURITIES REDEEMED IN PART.

               Upon the surrender of any Security which is to be redeemed only
in part 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), the Company shall execute,
and the Trustee shall authenticate and deliver to the Holder of such Security,
without service





                                       28
<PAGE>   35
charge, a new Security or Securities of the same series and Tranche, of any
authorized denomination requested by such Holder and of like tenor and in
aggregate principal amount equal to and in exchange for the unredeemed portion
of the principal of the Security so surrendered.

                                  ARTICLE FIVE

                                 SINKING FUNDS

SECTION 501. APPLICABILITY OF ARTICLE.

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

               The minimum amount of any sinking fund payment provided for by
the terms of Securities of any series, or any Tranche thereof, 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 Securities of any series, or
any Tranche thereof, is herein referred to as an "optional sinking fund
payment". If provided for by the terms of Securities of any series, or any
Tranche thereof, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 502. Each sinking fund payment shall be
applied to the redemption of Securities of the series or Tranche in respect of
which it was made as provided for by the terms of such Securities.

SECTION 502.  SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

               The Company (a) may deliver to the Trustee Outstanding
Securities (other than any previously called for redemption) of a series or
Tranche in respect of which a mandatory sinking fund payment is to be made and
(b) may apply as a credit Securities of such series or Tranche 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, in each case in satisfaction
of all or any part of such mandatory sinking fund payment; provided, however,
that no Securities shall be applied in satisfaction of a mandatory sinking fund
payment if such Securities shall have been previously so applied. Securities so
applied shall be received and credited for such purpose by the Trustee at the
Redemption Price specified in such Securities for redemption through operation
of the sinking fund and the amount of such mandatory sinking fund payment shall
be reduced accordingly.

 SECTION 503. REDEMPTION OF SECURITIES FOR SINKING FUND.

               Not less than 45 days prior to each sinking fund payment date
for the Securities of any series, or any Tranche thereof, the Company shall
deliver to the Trustee an Officer's Certificate specifying:

<PAGE>   36
               (a)  the amount of the next succeeding mandatory sinking fund
     payment for such series or Tranche;

               (b)  the amount, if any, of the optional sinking fund payment to
     be made together with such mandatory sinking fund payment;

               (c)  the aggregate sinking fund payment;

               (d)  the portion, if any, of such aggregate sinking fund payment
     which is to be satisfied by the payment of cash;

               (e)  the portion, if any, of such aggregate sinking fund payment
     which is to be satisfied by delivering and crediting Securities of such
     series or Tranche pursuant to Section 502 and stating the basis for such
     credit and that such Securities have not previously been so credited, and
     the Company shall also deliver to the Trustee any Securities to be so
     delivered. If the Company shall not deliver such Officer's Certificate,
     the next succeeding sinking fund payment for such series or Tranche shall
     be made entirely in cash in the amount of the mandatory sinking fund
     payment. Not less than 30 days before 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 403 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 404. Such notice having been
     duly given, the redemption of such Securities shall be made upon the terms
     and in the manner stated in Sections 405 and 406.


                                  ARTICLE SIX

SECTION 601. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

               The Company shall pay the principal of and premium, if any, and
interest, if any, on the Securities of each series in accordance with the terms
of such Securities and this Indenture.

SECTION 602. MAINTENANCE OF OFFICE OR AGENCY.

               The Company shall maintain in each Place of Payment for the
Securities of each series, or any Tranche thereof, an office or agency where
payment of such Securities shall be made, where the registration of transfer or
exchange of such Securities may be effected and where notices and demands to or
upon the Company in respect of such Securities and this Indenture may be
served.  The Company shall give prompt written notice to the Trustee of the
location, and any change in the location, of each such office or agency and
prompt notice to the Holders of any such change in the manner specified in
Section 106. If at any time the Company





                                       30
<PAGE>   37
shall fail to maintain any such required office or agency in respect of
Securities of any series, or any Tranche thereof, or shall fail to furnish the
Trustee with the address thereof, payment of such Securities shall be made,
registration of transfer or exchange thereof may be effected and notices and
demands in respect thereof may be served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent for all such
purposes in any such event.

               The Company may also from time to time designate one or more
other offices or agencies with respect to the Securities of one or more series,
or any Tranche thereof, for any or all of the foregoing purposes and may from
time to time rescind such designations; provided, however, that, unless
otherwise specified as contemplated by Section 301 with respect to the
Securities of such series or Tranche, no such designation or rescission shall
in any manner relieve the Company of its obligation to maintain an office or
agency for such purposes in each Place of Payment for such Securities in
accordance with the requirements set forth above.  The Company shall give
prompt written notice to the Trustee, and prompt notice to the Holders in the
manner specified in Section 106, of any such designation or rescission and of
any change in the location of any such other office or agency.

               Anything herein to the contrary notwithstanding, any office or
agency required by this Section may be maintained at an office of the Company,
in which event the Company shall perform all functions to be performed at such
office or agency.

SECTION 603. 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 the Securities of any series, or any Tranche thereof, it shall,
on or before each due date of the principal of and premium, if any, and
interest, if any, on any of such Securities, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum sufficient to pay the
principal and premium or interest so becoming due until such sums shall be paid
to such Persons or otherwise disposed of as herein provided. The Company shall
promptly notify the Trustee of any failure by the Company (or any other obligor
on such Securities) to make any payment of principal of or premium, if any, or
interest, if any, on such Securities.

               Whenever the Company shall have one or more Paying Agents for
the Securities of any series, or any Tranche thereof, it shall, on or before
each due date of the principal of and premium, if any, and interest, if any, on
such Securities, deposit with such Paying Agents sums sufficient (without
duplication) to pay the principal and premium or interest so becoming due, such
sum to be held in trust for the benefit of the Persons entitled to such
principal, premium or interest, and (unless such Paying Agent is the Trustee)
the Company shall promptly notify the Trustee of any failure by it so to act.

               The Company shall cause each Paying Agent for the Securities of
any series, or any Tranche thereof, other than the Company or 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 shall:





                                       31
<PAGE>   38
               (a)  hold all sums held by it for the payment of the principal
     of and premium, if any, or interest, if any, on such Securities in trust
     for the benefit of the Persons entitled thereto until such sums shall be
     paid to such Persons or otherwise disposed of as herein provided;

               (b)  give the Trustee notice of any failure by the Company (or
     any other obligor upon such Securities) to make any payment of principal
     of or premium, if any, or interest, if any, on such Securities; and

               (c)  at any time during the continuance of any such default,
     upon the written request of the Trustee, forthwith pay to the Trustee all
     sums so held in trust by such Paying Agent and furnish to the Trustee such
     information as it possesses regarding the names and addresses of the
     Persons entitled to such sums.

               The Company may at any time 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,
if so stated in a Company Order delivered to the Trustee, in accordance with
the provisions of Article Seven; 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 and
premium, if any, or interest, if any, on any Security and remaining unclaimed
for two years after such principal and premium, if any, 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, upon such
payment or discharge, the Holder of such Security shall, as an unsecured
general creditor and not as a Holder of an Outstanding Security, look only to
the Company for payment of the amount so due and payable and remaining unpaid,
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 payment to the Company, may at the
expense of the Company cause to be mailed, on one occasion only, notice to such
Holder 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 mailing,
any unclaimed balance of such money then remaining will be paid to the Company.

SECTION 604. CORPORATE EXISTENCE.

               Subject to the rights of the Company under Article Eleven, the
Company shall do or cause to be done all things necessary to preserve and keep
in full force and effect its corporate existence.

               Not later than September 30 in each year, commencing September
30, 1997, the Company shall deliver to the Trustee an Officer's Certificate
which need not comply with Section 102, executed by the principal executive
officer, the principal financial officer or the principal accounting officer of
the Company, as to such officer's knowledge of the Company's compliance with
all conditions and covenants under this Indenture, such compliance to be
determined without regard to any period of grace or requirement of notice under
this Indenture.

SECTION 606. WAIVER OF CERTAIN COVENANTS.

               The Company may omit in any particular instance to comply with
any term, provision or condition set forth in (a) Section 602 or any additional
covenant or restriction specified with respect to the Securities of any series,
or any Tranche thereof, as contemplated by Section 301 if before the time for
such compliance the Holders of at least a majority in aggregate principal
amount of the Outstanding Securities of all series and Tranches with respect to
which compliance with Section 602 or such additional covenant or restriction is
to be omitted, considered as one class, shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
term, provision or condition and (b) Section 604 or 605 or Article Eleven if
before the time for such compliance the Holders of at least a majority in
principal amount of Securities Outstanding under this Indenture shall, by Act
of such Holders, either waive such compliance in such instance or generally
waive compliance with such term, provision or condition; but, in the case of
(a) or (b), 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.

                           SATISFACTION AND DISCHARGE

SECTION 701. SATISFACTION AND DISCHARGE OF SECURITIES.

               Any Security or Securities, or any portion of the principal
amount thereof, shall be deemed to have been paid for all purposes of this
Indenture, and the entire indebtedness of the Company in respect thereof shall
be deemed to have been satisfied and discharged, if there shall have been
irrevocably deposited with the Trustee or any Paying Agent (other than the
Company), in trust:

               (a)  money in an amount which shall be sufficient, or

               (b)  in the case of a deposit made prior to the Maturity of such
     Securities or portions thereof, Eligible Obligations, which shall not
     contain provisions permitting the redemption or other prepayment thereof
     at the option of the issuer thereof, the principal of and the interest on
     which when due, without any regard to reinvestment thereof, will





                                       33
<PAGE>   40
     provide moneys which, together with the money, if any, deposited with or
     held by the Trustee or such Paying Agent, shall be sufficient, or

               (c)  a combination of (a) or (b) which shall be sufficient,

to pay when due the principal of and premium, if any, and interest, if any, due
and to become due on such Securities or portions thereof on or prior to
Maturity; provided, however, that in the case of the provision for payment or
redemption of less than all the Securities of any series or Tranche, such
Securities or portions thereof shall have been selected by the Security
Registrar as provided herein and, in the case of a redemption, the notice
requisite to the validity of such redemption shall have been given or
irrevocable authority shall have been given by the Company to the Trustee to
give such notice, under arrangements satisfactory to the Trustee; and provided,
further, that the Company shall have delivered to the Trustee and such Paying
Agent:

               (w)  if such deposit shall have been made prior to the Maturity
     of such Securities, a Company Order stating that the money and Eligible
     Obligations deposited in accordance with this Section shall be held in
     trust, as provided in Section 703;

               (x)  if Eligible Obligations shall have been deposited, an
     Opinion of Counsel that the obligations so deposited constitute Eligible
     Obligations and do not contain provisions permitting the redemption or
     other prepayment at the option of the issuer thereof, and an opinion of an
     independent public accountant of nationally recognized standing, selected
     by the Company, to the effect that the requirements set forth in clause
     (b) above have been satisfied;

               (y)  if such deposit shall have been made prior to the Maturity
     of such Securities, an Officer's Certificate stating the Company's
     intention that, upon delivery of such Officer's Certificate, its
     indebtedness in respect of such Securities or portions thereof will have
     been satisfied and discharged as contemplated in this Section; and

               (z)  if the Officer's Certificate required under clause (y)
     above is provided, an Opinion of Counsel to the effect that the Holders of
     such Securities and coupons, if any, of such series will not recognize
     income, gain or loss for Federal income tax purposes as a result of the
     Company's deposit and will be subject to Federal income tax in the same
     amount, in the same manner and at the same times as would have been the
     case if such deposit has not been made.

               Upon the deposit of money or Eligible Obligations, or both, in
accordance with this Section, together with the documents required by clauses
(w), (x), (y) and (z) above, the Trustee shall, upon receipt of a Company
Request, acknowledge in writing that the Security or Securities or portions
thereof with respect to which such deposit was made are deemed to have been
paid for all purposes of this Indenture and that the entire indebtedness of the
Company in respect thereof has been satisfied and discharged as contemplated in
this Section. In the event that all of the conditions set forth in the
preceding paragraph shall have been satisfied in respect of any Securities or
portions thereof except that, for any reason, the Officer's Certificate
specified





                                       34
<PAGE>   41
in clause (y) shall not have been delivered, such Securities or portions
thereof shall nevertheless be deemed to have been paid for all purposes of this
Indenture, and the Holders of such Securities or portions thereof shall
nevertheless be no longer entitled to the benefits of this Indenture or of any
of the covenants of the Company under Article Six (except the covenants
contained in Sections 602 and 603) or any other covenants made in  respect of
such Securities or portions thereof as contemplated by Section 301, but the
indebtedness of the Company in respect of such Securities or portions thereof
shall not be deemed to have been satisfied and discharged prior to Maturity for
any other purpose, and the Holders of such Securities or portions thereof shall
continue to be entitled to look to the Company for payment of the indebtedness
represented thereby; and, upon Company Request, the Trustee shall acknowledge
in writing that such Securities or portions thereof are deemed to have been
paid for all purposes of this Indenture.

               If payment at Stated Maturity of less than all of the Securities
of any series, or any Tranche thereof, is to be provided for in the manner and
with the effect provided in this Section, the Security Registrar shall select
such Securities, or portions of principal amount thereof, in the manner
specified by Section 403 for selection for redemption of less than all the
Securities of a series or Tranche.

               In the event that Securities which shall be deemed to have been
paid for purposes of this Indenture, and, if such is the case, in respect of
which the Company's indebtedness shall have been satisfied and discharged, all
as provided in this Section, do not mature and are not to be redeemed within
the 60 day period commencing with the date of the deposit of moneys or Eligible
Obligations, as aforesaid, the Company shall, as promptly as practicable, give
a notice, in the same manner as a notice of redemption with respect to such
Securities, to the Holders of such Securities to the effect that such deposit
has been made and the effect thereof.

               Notwithstanding that any Securities shall be deemed to have been
paid for purposes of this Indenture, as aforesaid, the obligations of the
Company and the Trustee in respect of such Securities under Sections 304, 305,
306, 404, 503 (as to notice of redemption), 602, 603, 907 and 914 and this
Article Seven shall survive.

               The Company shall pay, and shall indemnify the Trustee or any
Paying Agent with which Eligible Obligations shall have been deposited as
provided in this Section against, any tax, fee or other charge imposed on or
assessed against such Eligible Obligations or the principal or interest
received in respect of such Eligible Obligations, including, but not limited
to, any such tax payable by any entity deemed, for tax purposes, to have been
created as a result of such deposit.

               Anything herein to the contrary notwithstanding, (a) if, at any
time after a Security would be deemed to have been paid for purposes of this
Indenture, and, if such is the case, the Company's indebtedness in respect
thereof would be deemed to have been satisfied or discharged, pursuant to this
Section (without regard to the provisions of this paragraph), the Trustee or
any Paying Agent, as the case may be, shall be required to return the money or
Eligible Obligations, or combination thereof, deposited with it as aforesaid to
the Company or its representative under any applicable Federal or State
bankruptcy, insolvency or other similar law,





                                       35
<PAGE>   42
such Security shall thereupon be deemed retroactively not to have been paid and
any satisfaction and discharge of the Company's indebtedness in respect thereof
shall retroactively be deemed not to have been effected, and such Security
shall be deemed to remain Outstanding and (b) any satisfaction and discharge of
the Company's indebtedness in respect of any Security shall be subject to the
provisions of the last paragraph of Section 603.

SECTION 702. SATISFACTION AND DISCHARGE OF INDENTURE.

               This Indenture shall upon Company Request cease to be of further
effect (except as hereinafter expressly provided), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

               (a)  no Securities remain Outstanding hereunder; and

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

provided, however, that if, in accordance with the last paragraph of Section
701, any Security, previously deemed to have been paid for purposes of this
Indenture, shall be deemed retroactively not to have been so paid, this
Indenture shall thereupon be deemed retroactively not to have been satisfied
and discharged, as aforesaid, and to remain in full force and effect, and the
Company shall execute and deliver such instruments as the Trustee shall
reasonably request to evidence and acknowledge the same.

               Notwithstanding the satisfaction and discharge of this Indenture
as aforesaid, the obligations of the Company and the Trustee under Sections
304, 305, 306, 404, 503 (as to notice of redemption), 602, 603, 907 and 914 and
this Article Seven shall survive.

               Upon satisfaction and discharge of this Indenture as provided in
this Section, the Trustee shall assign, transfer and turn over to the Company,
subject to the lien provided by Section 907, any and all money, securities and
other property then held by the Trustee for the benefit of the Holders of the
Securities other than money and Eligible Obligations held by the Trustee
pursuant to Section 703.

SECTION 703. APPLICATION OF TRUST MONEY.

               Neither the Eligible Obligations nor the money deposited
pursuant to Section 701, nor the principal or interest payments on any such
Eligible Obligations, shall be withdrawn or used for any purpose other than,
and shall be held in trust for, the payment of the principal of and premium, if
any, and interest, if any, on the Securities or portions of principal amount
thereof in respect of which such deposit was made, all subject, however, to the
provisions of Section 603; provided, however, that, so long as there shall not
have occurred and be continuing an Event of Default any cash received from such
principal or interest payments on such Eligible Obligations, if not then needed
for such purpose, shall, to the extent practicable, be invested in Eligible
Obligations of the type described in clause (b) in the first paragraph of
Section 701 maturing at





                                       36
<PAGE>   43
such times and in such amounts as shall be sufficient to pay when due the
principal of and premium, if any, and interest, if any, due and to become due
on such Securities or portions thereof on and prior to the Maturity thereof,
and interest earned from such reinvestment shall be paid over to the Company as
received, free and clear of any trust, lien or pledge under this Indenture
except the lien provided by Section 907; and provided, further, that, so long
as there shall not have occurred and be continuing an Event of Default, any
moneys held in accordance with this Section on the Maturity of all such
Securities in excess of the amount required to pay the principal of and
premium, if any, and interest, if any, then due on such Securities shall be
paid over to the Company free and clear of any trust, lien or pledge under this
Indenture except the lien provided by Section 907; and provided, further, that
if an Event of Default shall have occurred and be continuing, moneys to be paid
over to the Company pursuant to this Section shall be held until such Event of
Default shall have been waived or cured.

     provided, however, that a valid extension of the interest payment period
     by the Company as contemplated in Section 312 of this Indenture shall not
     constitute a failure to pay interest for this purpose; or

               (b)  failure to pay the principal of or premium, if any, on any
     Security of such series within three Business Days after its Maturity
     (whether or not payment is prohibited by the provisions of Article Fifteen

     amount of the Outstanding Securities of such 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, unless the
     Trustee, or the Trustee and the Holders of a principal amount of
     Securities of such series not less than the principal amount of Securities
     the Holders of which gave such notice, as the case may be, shall agree in

                                       37
<PAGE>   44
     however, that the Trustee, or the Trustee and the Holders of such
     principal amount of Securities of such series, as the case may be, shall
     be deemed to have agreed to an extension of such period if corrective
     action is initiated by the Company within such period and is being
     diligently pursued; or

               (d)  the entry by a court having jurisdiction in the premises of
     (I) a decree or order for relief in respect of the Company in an

     such other decree or order shall have remained unstayed and in effect for
     a period of 90 consecutive days; or

               (e)  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 a case or

     bankruptcy or insolvency case or proceeding against it, or the filing by
     it of a petition or answer or consent seeking reorganization or relief

               If an Event of Default shall have occurred and be continuing
with respect to Securities of any series at the time Outstanding, then in every
such case the Trustee or the Holders of not less than 33% in principal amount
of the Outstanding Securities of such series may declare the principal amount
(or, if any of the Securities of such series are Discount Securities, such
portion of the principal amount of such Securities as may be specified in the
terms thereof as contemplated by Section 301) of all of the Securities of such
series to be due and payable immediately, by a notice in writing to the Company
(and to the Trustee if given by Holders), and upon receipt by the Company of
notice of such declaration such principal amount (or specified amount) shall
become immediately due and payable (provided that the payment of





                                       38
<PAGE>   45
principal of such securities shall remain subordinated to the extent provided
in Article Fifteen hereof); provided, however, that if an Event of Default
shall have occurred and be continuing with respect to more than one series of
Securities, the Trustee or the Holders of not less than 33% in aggregate
principal amount of the Outstanding Securities of all such series, considered
as one class, may make such declaration of acceleration, and not the Holders of
the Securities of any one of such series.

               At any time after such a declaration of acceleration with
respect to Securities of any series shall have been made and before a judgment
or decree for payment of the money due shall have been obtained by the Trustee
as hereinafter in this Article provided, the Event or Events of Default giving
rise to such declaration of acceleration shall, without further act, be deemed
to have been waived, and such declaration and its consequences shall, without
further act, be deemed to have been rescinded and annulled, if

               (a)  the Company shall have paid or deposited with the Trustee a
sum sufficient to pay

                      (1)  all overdue interest on all Securities of such
     series;

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

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

                      (4)  all amounts due to the Trustee under Section 907;
     and

               (b)  any other Event or Events of Default with respect to
Securities of such series, other than the non-payment of the principal of
Securities of such series which shall have become due solely by such
declaration of acceleration, shall have been cured or waived as provided in
Section 813.

               No such rescission shall affect any subsequent Event of Default
or impair any right consequent thereon.

SECTION 803.  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

               If an Event of Default described in clause (a) or (b) of Section
801 shall have occurred and be continuing, the Company shall, upon demand of
the Trustee, pay to it, for the benefit of the Holders of the Securities of the
series with respect to which such Event of Default shall have occurred, the
whole amount then due and payable on such Securities for principal and premium,
if any, and interest, if any, and, to the extent permitted by law, interest on
premium, if any, and on any overdue principal and interest, at the rate or
rates prescribed therefor in such





                                       39
<PAGE>   46
Securities, and, in addition thereto, such further amount as shall be
sufficient to cover any amounts due to the Trustee under Section 907.

               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 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.

               If an Event of Default with respect to Securities of any series
shall have occurred and be 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 804. TRUSTEE MAY FILE PROOFS OF CLAIM.

               In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition
or other judicial proceeding relative to the Company or any other obligor upon
the Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise,

               (a)  to file and prove a claim for the whole amount of
principal, premium, if any, and interest, if any, owing and unpaid in respect
of the Securities and to file such other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee (including
any claim for amounts due to the Trustee under Section 907) and of the Holders
allowed in such judicial proceeding, and

               (b)  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 amounts due it under Section 907.

               Nothing herein contained 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,





                                       40
<PAGE>   47
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.

SECTION 805.   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 in respect of which such judgment has
been recovered.

SECTION 806. APPLICATION OF MONEY COLLECTED.

               Subject to the provisions of Article Fifteen, 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 premium, if any, or
interest, if any, upon presentation of the Securities in respect of which or
for the benefit of which such money shall have been collected 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 907;

               SECOND: To the payment of the amounts then due and unpaid upon
the Securities for principal of and premium, if any, and interest, if any, 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, premium, if any, and
interest, if any, respectively; and

               THIRD: To the Company.

SECTION 807. LIMITATION ON SUITS.

               No Holder 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:

               (a)  such Holder shall have previously given written notice to
     the Trustee of a continuing Event of Default with respect to the
     Securities of such series;

               (b)  the Holders of not less than 33 1/3% in aggregate principal
     amount of the Outstanding Securities of all series in respect of which an
     Event of Default shall have





                                       41
<PAGE>   48
     occurred and be continuing, considered as one class, shall have made
     written request to the Trustee to institute proceedings in respect of such
     Event of Default in its own name as Trustee hereunder;

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

               (d)  the Trustee for 60 days after its receipt of such notice,
     request and offer of indemnity shall have failed to institute any such
     proceeding; and

               (e)  no direction inconsistent with such written request shall
     have been given to the Trustee during such 60-day period by the Holders of
     a majority in aggregate principal amount of the Outstanding Securities of
     all series in respect of which an Event of Default shall have occurred and
     be continuing, considered as one class;

               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 808.   UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
INTEREST.

               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 premium, if any, and
(subject to Sections 307 and 312) interest, if any, on such Security on the
Stated Maturity or Maturities expressed in such Security (or, in the case of
redemption, on the Redemption Date) and to institute suit for the enforcement
of any such payment, and such rights shall not be impaired without the consent
of such Holder.

SECTION 809. 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 shall have
been discontinued or abandoned for any reason, or shall have 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
such Holder shall be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
such Holder shall continue as though no such proceeding had been instituted.

SECTION 810. RIGHTS AND REMEDIES CUMULATIVE.





                                       42
<PAGE>   49
               Except as otherwise provided 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. 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 811. DELAY OR OMISSION NOT WAIVER.

               No delay or omission of the Trustee or of any Holder to exercise
any right or remedy accruing upon any Event of Default shall impair any such
right or remedy or constitute a waiver of any such Event of 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 812. CONTROL BY HOLDERS OF SECURITIES.

               If an Event of Default shall have occurred and be continuing in
respect of a series of Securities, the Holders of a majority in principal
amount of the Outstanding Securities of such 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, however, that
if an Event of Default shall have occurred and be continuing with respect to
more than one series of Securities, the Holders of a majority in aggregate
principal amount of the Outstanding Securities of all such series, considered
as one class, shall have the right to make such direction, and not the Holders
of the Securities of any one of such series; and provided, further, that

               (a)  such direction shall not be in conflict with any rule of
law or with this Indenture, and could not involve the Trustee in personal
liability in circumstances where indemnity would not, in the Trustee's sole
discretion, be adequate, and

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

SECTION 813. 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

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





                                       43
<PAGE>   50
               (b)  in respect of a covenant or provision hereof which under
Section 1202 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
and all Events of 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 814. UNDERTAKING FOR COSTS.

               The Company and the Trustee agree, and each Holder by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may
in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in
aggregate principal amount of the Outstanding Securities of all series in
respect of which such suit may be brought, considered as one class, or to any
suit instituted by any Holder for the enforcement of the payment of the
principal of or premium, if any, or interest, if any, on any Security on or
after the Stated Maturity or Maturities expressed in such Security (or, in the
case of redemption, on or after the Redemption Date).

SECTION 815. WAIVER OF 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 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.

                                  THE TRUSTEE

SECTION 901. CERTAIN DUTIES AND RESPONSIBILITIES.

               (a)  Except during the continuance of an Event of Default with
respect to Securities of any series,

               (1)  the Trustee undertakes to perform, with respect to
     Securities of such series, such duties and only such duties as are
     specifically set forth in this Indenture, and no implied covenants or
     obligations shall be read into this Indenture against the Trustee; and

               (2)  in the absence of bad faith on its part, the Trustee may,
     with respect to Securities of such series, conclusively rely, as to the
     truth of the statements and the correctness of the opinions expressed
     therein, upon certificates or opinions furnished to the Trustee and
     conforming to the requirements of this Indenture; but in the case of any
     such certificates or opinions which by any provision hereof are
     specifically required to be furnished to the Trustee, the Trustee shall be
     under a duty to examine the same to determine whether or not they conform
     to the requirements of this Indenture.

               (b)  In case an Event of Default with respect to Securities of
any series shall have occurred and be continuing, the Trustee shall exercise,
with respect to Securities of such series, such of the rights and powers vested
in it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

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

               (1)  this subsection shall not be construed to limit the effect
     of subsection (a) of this Section;

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

               (3)  the Trustee shall not be liable with respect to any action
     taken or omitted to be taken by it in good faith in accordance with the
     direction of the Holders of a majority in principal amount of the
     Outstanding Securities of any one or more series, as provided herein,
     relating to the time, method and place of conducting any proceeding for
     any remedy available to the Trustee, or exercising any trust or power
     conferred upon the Trustee, under this Indenture with respect to the
     Securities of such series; and





                                       45
<PAGE>   52
               (4)  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.

               (d)  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.

SECTION 902. NOTICE OF DEFAULTS.

               The Trustee shall give the Holders notice of any default
hereunder with respect to the Securities of any series to the Holders of
Securities of such series in the manner and to the extent required to do so by
the Trust Indenture Act, unless such default shall have been cured or waived;
provided, however, that in the case of any default of the character specified
in Section 801(c), no such notice to Holders shall be given until at least 75
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, an Event of Default.

SECTION 903. CERTAIN RIGHTS OF TRUSTEE.

               Subject to the provisions of Section 901 and to the applicable
provisions of the Trust Indenture Act:

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

               (b)  any request or direction of the Company mentioned herein
     shall be sufficiently evidenced by a Company Request or Company Order, or
     as otherwise expressly provided herein, and any resolution of the Board of
     Directors may be sufficiently evidenced by a Board Resolution;

               (c)  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 Officer's Certificate;

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

     the rights or powers vested in it by this Indenture at the request or
     direction of any Holder pursuant to this Indenture, unless such Holder

     the costs, expenses and liabilities which might be incurred by it in
     compliance with such request or direction;

               (f)  the Trustee shall not be bound to make any investigation

     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 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 (subject to applicable legal requirements) be
     entitled to examine, during normal business hours, the books, records and
     premises of the Company, personally or by agent or attorney;

               (g)  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; and

               (h)  except as otherwise provided in Section 801, the Trustee
     shall not be charged with knowledge of any Event of Default with respect
     to the Securities of any series for which it is acting as Trustee unless
     either (1) a Responsible Officer of the Trustee shall have actual
     knowledge of the Event of Default or (2) written notice of such Event of
     Default shall have been given to the Trustee by the Company, any other
     obligor on such Securities or by any Holder of such Securities.

SECTION 904.   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
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 905. MAY HOLD SECURITIES.

               Each of 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 908 and 913, may otherwise deal with the Company with the same
rights it would have if it were not the Trustee, Authenticating Agent, Paying
Agent, Security Registrar or such other agent.

SECTION 906. 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

it hereunder except as expressly provided herein or otherwise agreed with, and
for the sole benefit of, the Company.

SECTION 907. COMPENSATION AND REIMBURSEMENT.

               The Company shall

               (a)  pay to the Trustee from time to time reasonable

trustee of an express trust);

               (b)  except as otherwise expressly provided herein, reimburse
the Trustee upon its request for all reasonable expenses, disbursements and
advances reasonably incurred or made by the Trustee in accordance with any

that any such expense, disbursement or advance may be attributable to its
negligence, wilful misconduct or bad faith; and

               (c)  indemnify the Trustee and hold it harmless from and against
any loss, liability or expense reasonably incurred by it arising out of or in
connection with the acceptance or administration of the trust or trusts

expenses of defending itself against any claim or liability in connection with
the exercise or performance of any of its powers or duties hereunder, except to
the extent any such loss, liability or expense may be attributable to its
negligence, wilful misconduct or bad faith.

Company under this Section, the Trustee shall have a lien prior to the

other than property and funds held in trust under Section 703 (except as
otherwise provided in Section 703). "Trustee" for purposes of this Section

effect, and subject to the conditions, provided in the Trust Indenture Act and
this Indenture. For purposes of Section 310(b)(1) of the Trust Indenture Act
and to the extent permitted thereby, the Trustee, in its capacity as trustee in
respect of the Securities of any





                                       48

series, shall not be deemed to have a conflicting interest arising from its

SECTION 909. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

               There shall at all times be a Trustee hereunder which shall be

Columbia, authorized under such laws to exercise corporate trust powers, having

with the provisions of this Section, it shall resign immediately in the manner
and with the effect hereinafter specified in this Article.

Securities of one or more series by giving written notice thereof to the

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.

               (c)  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

<PAGE>   56
               (d)  If at any time:

               (1)  the Trustee shall fail to comply with Section 908 after
     written request therefor by the Company or by any Holder who has been a
     bona fide Holder for at least six months, or

               (2)  the Trustee shall cease to be eligible under Section 909

               (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, (x) the Company by a Board Resolution may remove the
Trustee with respect to all Securities or (y) subject to Section 814, any
Holder who has been a bona fide Holder 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.

               (e)  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
(other than as contemplated in clause (y) in subsection (d) of this Section),
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 911. 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
of Section 911, 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 911, any Holder who has been a
bona fide Holder of a Security of such series for at least six months may, on
behalf of itself 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.

               (f)  So long as no event which is, or after notice or lapse of
time, or both, would become, an Event of Default shall have occurred and be
continuing, and except with respect to a Trustee appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities
pursuant to subsection (e) of this Section, if the Company shall have delivered
to the





                                       50
<PAGE>   57
Trustee (i) a Board Resolution appointing a successor Trustee, effective as of
a date specified therein, and (ii) an instrument of acceptance of such
appointment, effective as of such date, by such successor Trustee in accordance
with Section 911, the Trustee shall be deemed to have resigned as contemplated
in subsection (b) of this Section, the successor Trustee shall be deemed to
have been appointed by the Company pursuant to subsection (e) of this Section
and such appointment shall be deemed to have been accepted as contemplated in
Section 911, all as of such date, and all other provisions of this Section and
Section 911 shall be applicable to such resignation, appointment and acceptance
except to the extent inconsistent with this subsection (f).

               (g)  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
by mailing written notice of such event by first-class mail, postage prepaid,

Trustee with respect to the Securities of such series and the address of its
corporate trust office.

Trustee shall, upon payment of all sums owed to it, 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

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
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





                                       51

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 those series to which the appointment of such successor Trustee relates;
but, on request of the Company or any successor Trustee, such retiring Trustee,
upon payment of all sums owed to it, shall duly assign, transfer and deliver to

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.

     possession of, or a lien upon, the goods, wares or merchandise or the
     receivables or proceeds arising from the sale of the goods, wares or
     merchandise previously constituting the security, provided the security is
     received by the Trustee simultaneously with the creation of the creditor
     relationship with the Company arising from the making, drawing,
     negotiating or incurring of the draft, bill of exchange, acceptance or
     obligation.

SECTION 914. CO-TRUSTEES AND SEPARATE TRUSTEES.

Holders of 33% in principal amount of the Securities then Outstanding, the
Company shall for such purpose join with the Trustee in the execution and
delivery of all instruments and agreements necessary or proper to appoint, one

powers as may be provided in the instrument of appointment, and to vest in such
Person or Persons, in the capacity aforesaid, any property, title, right or
power deemed necessary or desirable, subject to the other provisions of this

the receipt by it of a request so to do, or if an Event of Default shall have
occurred and be continuing, the Trustee alone shall have power to make such
appointment.

               Should any written instrument or instruments from the Company be
required by any co-trustee or separate trustee so appointed to more fully
confirm to such co-trustee or separate trustee such property, title, right or
power, any and all such instruments shall, on request, be executed,
acknowledged and delivered by the Company.

               Every co-trustee or separate trustee shall, to the extent
permitted by law, but to such extent only, be appointed subject to the
following conditions:

               (a)  the Securities shall be authenticated and delivered, and
     all rights, powers, duties and obligations hereunder in respect of the
     custody of securities, cash and other personal property held by, or

     or imposed upon the Trustee in respect of any property covered by such
     appointment shall be conferred or imposed upon and exercised or performed
     either by the Trustee or by the Trustee and such co-trustee or separate
     trustee jointly, as shall be provided in the instrument appointing such
     co-trustee or separate trustee, except to the extent that under any law of
     any jurisdiction in which any particular act is to be performed, the

     event such rights, powers,





                                       53
<PAGE>   60
     duties and obligations shall be exercised and performed by such co-trustee
     or separate trustee;

               (c)  the Trustee at any time, by an instrument in writing
     executed by it, with the concurrence of the Company, may accept the
     resignation of or remove any co-trustee or separate trustee appointed
     under this Section, and, if an Event of Default shall have occurred and be
     continuing, the Trustee shall have power to accept the resignation of, or
     remove, any such co-trustee or separate trustee without the concurrence of
     the Company. Upon the written request of the Trustee, the Company shall
     join with the Trustee in the execution and delivery of all instruments and
     agreements necessary or proper to effectuate such resignation or removal.
     A successor to any co-trustee or separate trustee so resigned or removed
     may be appointed in the manner provided in this Section;

               (d)  no co-trustee or separate trustee hereunder shall be
     personally liable by reason of any act or omission of the Trustee, or any
     other such trustee hereunder; and

               (e)  any Act of Holders delivered to the Trustee shall be deemed
     to have been delivered to each such co-trustee and separate trustee.


SECTION 915. APPOINTMENT OF AUTHENTICATING AGENT.

               The Trustee may appoint an Authenticating Agent or Agents with
respect to the Securities of one or more series, or any Tranche thereof, which
shall be authorized to act on behalf of the Trustee to authenticate Securities
of such series or Tranche issued upon original issuance, exchange, registration
of transfer 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, any State or territory thereof or the
District of Columbia or the Commonwealth of Puerto Rico, 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.





                                       54
<PAGE>   61
               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. 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 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, in accordance
with and subject to the provisions of Section 907.

               The provisions of Sections 308, 904 and 905 shall be applicable
to each Authenticating Agent.

               If an appointment with respect to the Securities of one or more
series, or any Tranche thereof, shall be made pursuant to this Section, the
Securities of such series or Tranche may have endorsed thereon, in addition to
the Trustee's certificate of authentication, an alternate certificate of
authentication substantially in the following form:

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

               If all of the Securities of a series may not be originally
issued at one time, and if the Trustee does not have an office capable of
authenticating Securities upon original issuance located in a Place of Payment
where the Company wishes to have Securities of such series authenticated upon
original issuance, the Trustee, if so requested by the Company in writing
(which writing need not comply with Section 102 and need not be accompanied by
an Opinion of Counsel), shall appoint, in accordance with this Section and in
accordance with such procedures as shall be acceptable to the Trustee, an
Authenticating Agent having an office in a Place of Payment designated by the
Company with respect to such series of Securities.

     change, elimination or addition shall become effective with respect to
     such series or Tranche only pursuant to the provisions of Section 1202

<PAGE>   65
     add to or change any of the provisions of this Indenture as shall be

               Without limiting the generality of the foregoing, if the Trust
Indenture Act as in effect at the date of the execution and delivery of this
Indenture or at any time thereafter shall be amended and

               (x)  if any such amendment shall require one or more changes to
any provisions hereof or the inclusion herein of any additional provisions, or
shall by operation of law be deemed to effect such changes or incorporate such
provisions by reference or otherwise, this Indenture shall be deemed to have
been amended so as to conform to such amendment to the Trust Indenture Act, and
the Company and the Trustee may, without the consent of any Holders, enter into
an indenture supplemental hereto to effect or evidence such changes or
additional provisions; or

               (y)  if any such amendment shall permit one or more changes to,

Trust Indenture Act to be contained herein, this Indenture shall be deemed to
have been amended to effect such changes or elimination, and the Company





                                       59
<PAGE>   66
and the Trustee may, without the consent of any Holders, enter into an
indenture supplemental hereto to evidence such amendment hereof.

SECTION 1202. SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

               With the consent of the Holders of not less than a majority in
aggregate principal amount of the Securities of all series then Outstanding
under this Indenture, considered as one class, by Act of said Holders delivered
to the Company and the Trustee, the Company, when authorized by a Board
Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to, or changing in
any manner or eliminating any of the provisions of, this Indenture; provided,
however, that if there shall be Securities of more than one series Outstanding
hereunder and if a proposed supplemental indenture shall directly affect the
rights of the Holders of Securities of one or more, but less than all, of such
series, then the consent only of the Holders of a majority in aggregate
principal amount of the Outstanding Securities of all series so directly
affected, considered as one class, shall be required; and provided, further,
that if the Securities of any series shall have been issued in more than one
Tranche and if the proposed supplemental indenture shall directly affect the
rights of the Holders of Securities of one or more, but less than all, of such
Tranches, then the consent only of the Holders of a majority in aggregate
principal amount of the Outstanding Securities of all Tranches so directly
affected, considered as one class, shall be required; and provided, further,
that no such supplemental indenture shall:

               (a)  change the Stated Maturity of the principal of, or any
installment of principal of or interest on (except as provided in Section 312
hereof), any Security, or reduce the principal amount thereof or the rate of
interest thereon (or the amount of any installment of interest thereon) or
change the method of calculating such rate or reduce any premium payable upon
the redemption thereof, or reduce the amount of the principal of a Discount
Security that would be due and payable upon a declaration of acceleration of
the Maturity thereof pursuant to Section 802, or change the coin or currency
(or other property), in which any Security or any premium or the interest
thereon is payable, or impair the right to institute suit for the enforcement
of any such payment on or after the Stated Maturity of any Security (or, in the
case of redemption, on or after the Redemption Date), without, in any such
case, the consent of the Holder of such Security, or

               (b)  reduce the percentage in principal amount of the
Outstanding Securities of any series or any Tranche thereof, the consent of the
Holders of which is required for any such supplemental indenture, or the
consent of the Holders of which is required for any waiver of compliance with
any provision of this Indenture or of any default hereunder and its
consequences, or reduce the requirements of Section 1304 for quorum or voting,
without, in any such case, the consent of the Holders of each Outstanding
Security of such series or Tranche, or

               (c)  modify any of the provisions of this Section, Section 606
or Section 813 with respect to the Securities of any series, or any Tranche
thereof, or except to increase the percentages in principal amount referred to
in this Section or such other Sections or to provide that other provisions of
this Indenture cannot be modified or waived without the consent of the Holder
of each Outstanding Security affected thereby; provided, however, that this
clause shall





                                       60
<PAGE>   67
not be deemed to require the consent of any Holder with respect to changes in
the references to "the Trustee" and concomitant changes in this Section, or the
deletion of this proviso, in accordance with the requirements of Sections
911(b) and 1201(h).

               A supplemental indenture which changes or eliminates any
covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or of
one or more Tranches thereof, or which modifies the rights of the Holders of
Securities of such series or Tranches with respect to such covenant or other
provision, shall be deemed not to affect the rights under this Indenture of the
Holders of Securities of any other series or Tranche.

               It shall not be necessary for any Act of Holders under this
Section to approve the particular form of any proposed supplemental indenture,
but it shall be sufficient if such Act shall approve the substance thereof. A
waiver by a Holder of such Holder's right to consent under this Section shall
be deemed to be a consent of such Holder.

SECTION 1203. EXECUTION OF SUPPLEMENTAL INDENTURES.

               In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby
of the trusts created by this Indenture, the Trustee shall be entitled to
receive, and (subject to Section 901) shall be fully protected in relying upon,
an Opinion of Counsel stating that the execution of such supplemental indenture
is authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties, immunities or liabilities under this Indenture or
otherwise.

SECTION 1204. EFFECT OF SUPPLEMENTAL INDENTURES.

               Upon the execution of any supplemental indenture under this
Article this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes;
and every Holder of Securities theretofore or thereafter authenticated and
delivered hereunder shall be bound thereby. Any supplemental indenture
permitted by this Article may restate this Indenture in its entirety, and, upon
the execution and delivery thereof, any such restatement shall supersede this
Indenture as theretofore in effect for all purposes.

SECTION 1205. CONFORMITY WITH TRUST INDENTURE ACT.

               Every supplemental indenture executed pursuant to this Article
shall conform to the requirements of the Trust Indenture Act as then in effect.

 SECTION 1206. REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

               Securities of any series, or any Tranche thereof, authenticated
and delivered after the execution of any supplemental indenture pursuant to
this Article may, and shall if required by





                                       61
<PAGE>   68
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities of any series, or any Tranche thereof, so modified as to
conform, in the opinion of the Trustee and the Company, to any such
supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding
Securities of such series or Tranche.

SECTION 1207. MODIFICATION WITHOUT SUPPLEMENTAL INDENTURE.

               If the terms of any particular series of Securities shall have
been established in a Board Resolution or an Officer's Certificate pursuant to
a Board Resolution as contemplated by Section 301, and not in an indenture
supplemental hereto, additions to, changes in or the elimination of any of such
terms may be effected by means of a supplemental Board Resolution or Officer's
Certificate, as the case may be, delivered to, and accepted by, the Trustee;
provided, however, that such supplemental Board Resolution or Officer's
Certificate shall not be accepted by the Trustee or otherwise be effective
unless all conditions set forth in this Indenture which would be required to be
satisfied if such additions, changes or elimination were contained in a
supplemental indenture shall have been appropriately satisfied. Upon the
acceptance thereof by the Trustee, any such supplemental Board Resolution or
Officer's Certificate shall be deemed to be a "supplemental indenture" for
purposes of Section 1204 and 1206.

such series and Tranches; provided, however, that if any action is to be taken
at such meeting which this Indenture expressly provides may be taken by the
Holders of a specified percentage, which is less than a majority, in principal
amount of the Outstanding Securities of such series and Tranches, considered as
one class, the Persons entitle to vote such specified percentage in principal

<PAGE>   70
prior to the adjournment of such meeting.  In the absence of a quorum at any

               (a)  Attendance at meetings of Holders of Securities may be in
person or by proxy; and, to the extent permitted by law, any such proxy shall

Holder or future Holder of such Securities before being voted.

               (b)  Notwithstanding any other provisions of this Indenture, the

Securities and of the appointment of proxies and in regard to the appointment
and duties of inspectors of votes, the submission and examination of proxies,
certificates and other evidence of the right to vote, and such other matters
concerning the conduct of the meeting as it shall deem appropriate. Except as
otherwise permitted or required by any such regulations, the holding of
Securities shall be proved in the manner specified in Section 104 and the
appointment of any proxy shall be proved in the manner specified in Section
104. Such regulations may provide that written instruments appointing proxies,
regular on their face, may be presumed valid and genuine without the proof
specified in Section 104 or other proof.

               (c)  The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders as provided in Section 1302(b), in which case the
Company or the Holders of Securities of the series and Tranches calling the

of the meeting to be not Outstanding. The chairman of the meeting shall have no
right to vote, except as a Holder of a Security or proxy.

and the meeting may be held as so adjourned without further notice.

SECTION 1306. COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

               The vote upon any resolution submitted to any meeting of Holders
shall be by written ballots on which shall be subscribed the signatures of the

them. The permanent chairman of the meeting shall appoint two inspectors of

verified by the affidavits of the permanent chairman and secretary of the
meeting and one such copy shall be delivered to the Company, and another to the
Trustee to be preserved by the Trustee, the latter to have attached thereto the
ballots voted at the meeting. Any record so signed and verified shall be
conclusive evidence of the matters therein stated.

 SECTION 1307. ACTION WITHOUT MEETING.

               In lieu of a vote of Holders at a meeting as hereinbefore
contemplated in this Article, any request, demand, authorization, direction,

by written instruments as provided in Section 104.

indebtedness represented thereby, or upon any obligation, covenant or agreement
under this Indenture, against any incorporator, member, stockholder, officer,
employee or director, as such, past, present or future of the Company or of any
predecessor or successor corporation (either directly or through the Company or
a predecessor or successor corporation), whether by virtue of any
constitutional provision, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise; it being expressly agreed and understood
that this Indenture and all the Securities are solely corporate obligations,
and that no personal liability whatsoever shall attach to, or be incurred by,
any incorporator, member, stockholder, officer, employee or director, past,
present or future, of the Company or of any predecessor or successor
corporation, either directly or indirectly through the Company or any
predecessor or successor corporation, because of the indebtedness hereby

accelerate the maturity thereof (or of the indebtedness secured thereby), and
such event of default shall not have been cured or waived and shall not have
ceased to exist.  Upon (i) any acceleration of the principal amount due on any
Security or (ii) any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities, to creditors upon
any dissolution or winding-up or total or partial liquidation or reorganization
of the Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all principal of and premium, if any, and
interest due or to become due upon all Senior Indebtedness shall first be paid
in full, or payment thereof provided for in money or money's worth, before any
payment is made on account of the principal of or interest on the indebtedness
evidenced by such Security, and upon any such dissolution or winding-up or
liquidation or reorganization any payment or distribution of assets of the
Company of any kind or character, whether in cash, property or securities
(other than securities of the Company or any other corporation provided for by
a plan of reorganization or readjustment, the payment of which is subordinated,
at least to the extent provided in this Article Fifteen, to the payment in full
of all Senior Indebtedness, provided the rights of the holders of Senior
Indebtedness are not altered by such reorganization or readjustment) to which
the holder thereof would be entitled, except for the provisions hereof, shall
be paid by the Company or by any receiver, trustee in bankruptcy, liquidating
trustee, agent or other person making such payment or distribution, or by the
holder of any Security if received by it, directly to the holders of Senior
Indebtedness (pro rata to each such holder on the basis of the respective
amounts of Senior Indebtedness held by such holder) or their representatives,
to the extent necessary to pay all Senior Indebtedness in full in money or
money's worth after giving effect to any concurrent payment or distribution to
or for the holders of Senior Indebtedness.  In the event that any payment or
distribution of assets of the Company of any kind or character, whether in
cash, property or securities, not permitted by the foregoing shall be received
by the holder of any Security before all Senior Indebtedness is paid in full,
or provision made for such payment, in accordance with its terms, such payment
or distribution shall be held for the benefit of, and shall be paid over or
delivered to, the holders of such Senior Indebtedness or their representative
or representatives or to the trustee or trustees under any indenture pursuant
to which any instruments evidencing any of such Senior Indebtedness may have
been issued or under which such instruments are issued, as their respective
interests may appear, for application to the payment of all Senior Indebtedness
remaining unpaid to the extent necessary to pay all such Senior Indebtedness in
full in accordance with its terms, after giving effect to any concurrent
payment or distribution to or for the holders of such Senior Indebtedness.  The
provisions of this Article Fifteen are solely for the purpose of defining the
relative rights of the holders of Senior Indebtedness on the one hand and the
holders of Securities on the other hand, and nothing herein shall impair, as
between the Company and such  holders, the obligation of the Company, which is
unconditional and absolute, to pay to the holders the principal thereof and the
interest thereon in accordance with the terms thereof, nor shall anything
herein prevent the holder thereof from exercising all remedies otherwise
permitted by applicable law or hereunder upon default hereunder, all subject to
the rights, if any, under this Article Fifteen of holders of Senior
Indebtedness to receive cash, property or securities otherwise payable or
deliverable to the holders of Securities.  Each such holder by its acceptance
thereof acknowledges and agrees that the foregoing subordination provisions
are, and are intended to be, an inducement and a consideration to each holder
of any Senior Indebtedness, whether such Senior Indebtedness was





                                       67
<PAGE>   74
created or acquired before or after the issuance of such Securities, to acquire
and/or continue to hold such Senior Indebtedness, and such holder of Senior
Indebtedness shall be deemed conclusively to have relied on such subordination
provisions in acquiring and/or continuing to hold such Senior Indebtedness.
Subject to the payment in full of all Senior Indebtedness, the holders of
Securities shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of assets of the Company
applicable to the Senior Indebtedness until such Securities shall be paid in
full, and no such payments or distributions to the holders of Senior
Indebtedness shall, as between the Company, its creditors other than the
holders of Senior Indebtedness and the holders of Securities, be deemed to be a
payment by the Company to or on account of any Security.  Upon any payment or
distribution of assets of the Company referred to in this Article Fifteen, the
holder of any Security and the Trustee shall be entitled to rely upon a
certificate of the liquidating trustee or agent or other person making any
distribution to the holder of such Security or the Trustee for the purpose of
ascertaining the persons entitled to participate in such distribution, the
holders of the Senior Indebtedness and other indebtedness of the Company, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article Fifteen.  The
holder of any Security, by its acceptance hereof, authorizes and directs the
Company in its behalf to take such action as may be necessary or appropriate to
effectuate the subordination as provided in this Article Fifteen and appoints
the Company its attorney in fact for any and all such purposes.

               NATIONAL RURAL UTILITIES COOPERATIVE FINANCE CORPORATION, a
cooperative association duly organized and existing under the laws of the
District of Columbia (herein referred to as the "Company", which term includes
any successor Person under the Indenture), for value received, hereby promises
to pay to CEDE & CO., or registered assigns, the principal sum of $75,000,000
on September 15, 2046, to pay interest on said principal sum from September 15,
1997 or from the most recent Interest Payment Date through which interest has
been paid or duly provided for, quarterly in arrears on March 15, June 15,
September 15 and December 15 of each year, commencing December 15, 1997 at the
rate of 7.65% per annum to, but not including, the date on which the principal
hereof is paid or made available for payment. The amount of interest payable on
any Interest Payment Date shall be computed on the basis of a 360-day year of
twelve 30-day months. In the event that any date on which interest is payable
on the Securities is not a Business Day, then payment of the interest payable
on such date will be made on the next succeeding day which is a Business Day
(and without any interest or other payment in respect of any such delay),
except that, if such Business Day is in the next succeeding calendar year, such
payment will be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date.  A "Business Day" is
any day other than a day on which banking institutions in New York City are





                                       1

authorized or obligated by law to close.  The interest so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in such Indenture, be paid to the Person in whose name this Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest, which shall be the Business Day
next preceding such Interest Payment Date. Any such interest not so punctually
paid or duly provided for will forthwith cease to be payable to the Holder on
such Regular Record Date and may either be paid to the Person in whose name
this Security (or one or more Predecessor Securities) is registered at the
close of business on a Special Record Date for the payment of such Defaulted
Interest to be fixed by the Trustee, notice whereof shall be given to Holders
of Securities of this series not less than 10 days prior to such Special Record
Date, or be paid at any time in any other lawful manner not inconsistent with
the requirements of any securities exchange on which the Securities of this
series may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in the Indenture referred to on the reverse hereof.

               Payment of the principal of and interest on this Security will
be made at the office or agency of the Company maintained for that purpose in
the Borough of Manhattan, the City and State of New York, in such coin or
currency of the United States of America at the time of payment is legal tender
for payment of public and private debts.

               Reference is hereby made to the further provisions of this
Security set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if forth at this place.

               Unless the certificate of authentication hereon has been
executed by the Trustee referred to on the reverse hereof by manual signature,
this Security shall not be entitled to any benefit under the Indenture or be
valid or obligatory for any purpose.

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

                                REVERSE OF QUICS

               This Security is one of a duly authorized issue of securities of
the Company (herein called the "Securities"), issued and to be issued
in one or more series under an Indenture, dated as of October 15, 1996, 
(herein as from time to time amended called the "Indenture", which term shall
have the meaning assigned to it in such instrument), between the Company and
Mellon Bank, N.A., as Trustee (herein called the "Trustee", which term includes
any successor trustee under the Indenture), and reference is hereby made to the
Indenture for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Trustee and the Holders of
the Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. This Security is one of the series designated on
the face hereof, limited in aggregate principal amount to $75,000,000.

               The Securities of this series are subject to redemption upon not
less than 30 nor more than 60 days' notice by mail, at any time on or after
September 15, 2002 as a whole or in part, at the election of the Company, at a
Redemption Price equal to 100% of the principal amount, together in the case of
any such redemption with accrued interest to, but not including, the Redemption
Date, but interest installments whose Stated Maturity is on or prior to such
Redemption Date will be payable to the Holder of such Security, or one or more
Predecessor Securities, of record at the close of business on the related
Regular Record Date referred to on the face hereof, all as provided in the
Indenture.  If a partial redemption would result in a delisting of the
Securities from any national securities exchange on which the Securities are
then listed, the Company may redeem such Securities only in whole.

               In the event of redemption of this Security in part only, a new
Security or Securities of this series and of like tenor for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon the
cancellation hereof.

               The indebtedness evidenced by this Security is, to the extent
provided in the Indenture, subordinated and subject in right of payment to the
prior payment in full of all Senior Indebtedness, and this Security is issued
subject to the provisions of the Indenture with respect thereto. Each Holder of
this Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his behalf to take such
action as may be necessary or appropriate to acknowledge or effectuate the
subordination so provided and (c) appoints the Trustee his attorney-in-fact for
any and all such purposes. Each Holder hereof, by his acceptance hereof, hereby
waives all notice of the acceptance of the subordination provisions contained
herein and in the Indenture by each holder of Senior Indebtedness, whether now
outstanding or hereafter incurred, and waives reliance by each such Holder upon
said provisions.

               The Indenture contains provisions for defeasance at any time of
the entire indebtedness of this Security upon compliance with certain
conditions set forth in the Indenture.

               If an Event of Default with respect to Securities of this series
shall occur and be continuing, the principal of the Securities of this series
may be declared due and payable in the manner and with the effect provided in
the Indenture.





                                       4
<PAGE>   5
               In addition to the events of default set forth in the Indenture,
the following will constitute an Event of Default under the Indenture with
respect to the Securities:  the Company shall pay any dividend or interest on,
or principal of, or redeem, purchase, acquire or make a liquidation payment
with respect to, any Members' Subordinated Certificates, Members' Equity or
patronage capital, if such payment is made during an Extension Period, and
either (i) such Extension Period has not expired or been terminated or (ii) the
Company had not made all payments due on the Securities as a result of such
expiration or termination.

               The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities of
each series to be affected under the Indenture at any time by the Company and
the Trustee with the consent of the Holders of a majority in principal amount
of the Securities at the time Outstanding of each series to be affected. The
Indenture also contains provisions permitting the Holders of specified
percentages in principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, to
waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.

               As provided in and subject to the provisions of the Indenture,
the Holder of this Security shall not have the right to institute any
proceeding with respect to the Indenture or for the appointment of a receiver
or trustee or for any other remedy thereunder, unless such Holder shall have
previously given the Trustee written notice of a continuing Event of Default
with respect to the Securities of this series, the Holders of not less than
33-1/3% in aggregate principal amount of the Securities of this series at the
time Outstanding shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default as Trustee and offered the
Trustee reasonable indemnity, and the Trustee shall not have received from the
Holders of a majority in aggregate principal amount of Securities of this
series at the time Outstanding a direction inconsistent with such request, and
shall have failed to institute any such proceeding, for 60 days after receipt
of such notice, request and offer of indemnity. The foregoing shall not apply
to any suit instituted by the Holder of this Security for the enforcement of
any payment of principal hereof or interest hereon on or after the respective
due dates expressed herein.

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





                                      5
<PAGE>   6

               The Company shall have the right at any time and from time to
time during the term of the Securities of this series to extend the interest
payment period to a period not exceeding 20 consecutive quarters (an "Extended
Interest Payment Period"), and at the end of such Extended Interest Payment
Period or upon the date of the termination of the Extended Interest Payment
Period if prior to the end, the Company shall pay all interest then accrued and
unpaid (together with interest thereon at the same rate as specified for the
Securities of this series to the extent permitted by applicable law) through
the last day of such Extended Interest Payment Period provided that if any
principal amount of this Security is paid on such day, then not including
interest for such day with respect to such principal amount; provided, that
during such Extended Interest Payment Period the Company may not declare or pay
any dividend on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any of its Members' Subordinated Certificates, Members' Equity
or patronage capital.  Prior to the termination of any such Extended Interest
Payment Period, the Company may further extend the interest payment period,
provided that such Extended Interest Payment Period, together with all such
previous and further extensions thereof, may not exceed 20 consecutive quarters
or extend beyond the Stated Maturity of the Securities of this series. Upon the
termination of any such Extended Interest Payment Period and the payment of all
amounts then due, the Company may select a new Extended Interest Payment
Period, subject to the above requirements. No interest during an Extended
Interest Payment Period, except at the end thereof, shall be due and payable.
The Company shall give the Holder of this Security notice of its selection of
such Extended Interest Payment Period as provided in the Indenture.

               The Securities of this series are issuable only in registered
form without coupons in denominations of $25 and any integral multiple thereof.
As provided in the Indenture and subject to certain limitations therein set
forth, Securities of this series are exchangeable for a like aggregate
principal amount of Securities of this series and of like tenor and of
authorized denominations, as requested by the Holder surrendering the same.

               No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge payable in connection therewith.

               The Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Security is registered as the
absolute owner hereof for all purposes, whether or not this Security be
overdue, and neither the Company, the Trustee nor any such agent shall be
affected by notice to the contrary.

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

Dear Sirs:

               We have acted as special counsel to National Rural Utilities
Cooperative Finance Corporation, a District of Columbia cooperative association
("CFC"), in connection with the proposed public offering of Quarterly Income
Capital Securities, as decribed in CFC's Registration Statement on Form S-3
