Maturity and in such case the overdue principal of this Security shall bear
interest at the rate of     % per annum (to the extent that the payment of such
interest shall be permitted by applicable law), which shall accrue from the date
of such default in payment to the date payment of such principal has been made

the date of such demand for payment to the date payment of such interest has
been made or duly provided for, and such interest shall also be payable on

     Payment of the principal of (and premium, if any) and [IF APPLICABLE,
INSERT--any such] interest on this Security will be made at the office or agency

Company in Boise, Idaho, so long as the Company shall maintain an office in
Boise for such purpose, in such coin or currency of the United States of America

debts; PROVIDED, HOWEVER that at the option of the Company payment of interest
may be made by check mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register.

     The indebtedness evidenced by this Security is, to the extent provided in
the Indenture, subordinate and subject in right of payments to the prior payment
in full of all Senior Indebtedness (as defined in the Indenture), 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 actions as may be necessary or appropriate to 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, 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.

     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 set 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.

all Securities, or such one or more series of Securities, to waive compliance by
the Company with certain provisions 





                                      -19-

the Securities and performance of every covenant of the Indenture on the part of
the predecessor corporation to be performed, and shall be substituted for the
predecessor corporation under the Indenture; and in the event of any such
transfer, such predecessor corporation shall be discharged from all obligations

series, the Securities of such series shall be issuable in denominations of

SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its President or one of its Vice Presidents, under its corporate
seal reproduced thereon attested by its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on the Securities may be

     Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper 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 of such Securities.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. In
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 601) shall be fully protected in
relying upon, an Opinion of Counsel stating,

          (a) that the form of such Securities has been established in
     conformity with the provisions of this Indenture;




                                      -24-




          (b) that the terms of such Securities have been established in
     conformity with the provisions of this Indenture; and

          (c) that such Securities, when authenticated and delivered by the
     Trustee and issued by the Company in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Company, enforceable in accordance with
     their terms, subject to bankruptcy, insolvency, reorganization and other
     laws of general applicability relating to or affecting the enforcement of
     creditors' rights and to general equity principles.

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

     Notwithstanding the provisions of Section 301 and this Section 303, if all
Securities of a series are not to be originally issued at one time, it shall not
be necessary to deliver the Officers Certificate otherwise required pursuant to
Section 301 or the Company Order and Opinion of Counsel otherwise required
pursuant to such preceding paragraph at or prior to the time of authentication
of each Security of such series if such documents are delivered at or prior to
the time of authentication and delivery upon original issuance of the first
Security of such series to be issued and, if such other documents reasonably
apply to the authentication and delivery of such other Security.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder and is entitled to the
benefits of this Indenture. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 309 together with a written statement
stating that 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 of this Indenture.

SECTION 304.  TEMPORARY SECURITIES.



                                      -25-




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

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

SECTION 305.  REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

     The Company shall cause to be kept at its office in Boise, Idaho,
designated pursuant to Section 1002, a register (being herein sometimes referred
to as the "Security Register") in which, subject to such reasonable regulations
as it may prescribe, the Company shall provide for the registration of
Securities and of transfers of Securities.

     The Company initially shall act as "Security Registrar" at such office for
the purpose of registering Securities and transfers of Securities as herein
provided. If at any time the Company shall determine not to act as Security
Registrar or shall fail to maintain a Security Register, the Company hereby
appoints the Trustee as its agent to maintain a Security Register and to act as
Security Registrar. At all reasonable times, the Security Register shall be open
for inspection by the Trustee.

     Upon surrender for registration of transfer of any Security of any series
at the office or agency in a Place of Payment for that series, the Company shall
cancel the surrendered Security, record the transaction in the Security Register
and either issue or cause to be issued one or more new Securities of the same
series, of any authorized denominations and of a like aggregate principal amount
and tenor or, at the direction of the Trustee, an Authenticating Agent or any
other agent acceptable to the Trustee, credit the proper principal amount of
such Securities to the account of the Person entitled thereto maintained in the
Security Register. Upon request, the Company shall issue or cause to be 




                                      -26-




issued one or more new Securities of the same series, of authorized
denominations and of an aggregate principal amount requested, up to the amount
held in the account of such person.

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

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

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

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

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

     Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any Global Security shall be exchangeable pursuant
to this Section 305 for Securities registered in the names of Persons other than
the Depositary for such series or its nominee if, but only if, (i) such
Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for such Global Security or at any time ceases to be a clearing
agency registered as such under the Securities Exchange Act of 1934, as 




                                      -27-




amended, (ii) the Company executes and delivers to the Trustee a Company Order
that such Global Security shall be so exchangeable or (iii) there shall have
occurred and be continuing an Event or Default with respect to the Securities of
such series. And Global Security that is exchangeable pursuant to the preceding
sentence shall be exchangeable for Securities registered in such names as such
Depositary shall direct.

     Notwithstanding any other provision of this Indenture, a Global Security
may not be transferred except as a whole by the Depositary for such Global
Security to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary.

SECTION 306.  MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

     If any mutilated Security is surrendered to the Trustee or the Company, in
exchange therefor a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding shall be
executed, authenticated and delivered.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company may execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding. In case any such
mutilated, destroyed, lost or stolen Security has become or is about to become
due and payable and the Holder has complied with the provisions of the second
paragraph of this Section, the Company in its discretion may, instead of issuing
a new Security, pay or authorize the payment of such Security without surrender
thereof except in the case of a mutilated 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 another expenses (including
the fees and expenses of the Trustee) connected therewith.

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




                                      -28-




equally and proportionately with any and all other Securities of that series
duly issued hereunder.

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

SECTION 307.  PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

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

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

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




                                      -29-




     such Defaulted Interest and the Special Record Date therefor having been so
     mailed, such Defaulted Interest shall be paid to the Persons in whose names
     the Securities of such series (or their respective Predecessor Securities)
     are registered at the close of business on such Special Record Date and
     shall no longer be payable pursuant to the following Clause (2).

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

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

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 any Security is registered as the owner of such
Security for the purpose of receiving payment of principal of (and premium, if
any) and (subject to Section 307) interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

     No holder of any beneficial interest in any Global Security held on its
behalf by a Depositary shall have any rights under this Indenture with respect
to such Global Security, and such Depositary shall be treated by the Company,
the Trustee, and any agent of the Company or the Trustee as the owner of such
Global Security for all purposes whatsoever. 

SECTION 309. CANCELLATION.

     All Securities surrendered for registration of transfer or exchange shall,
if surrendered to any Person other than the Security Registrar, be delivered to
the Security Registrar and shall be promptly cancelled by it. The Company may at
any time deliver to the Security Registrar, or if the Company is acting in such
capacity to the Trustee or the Authenticating Agent, for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever and may deliver to the Trustee (or
any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly cancelled by the 




                                      -30-




Security Registrar, the Trustee or the Authenticating Agent. No Securities shall
be authenticated in lieu of or in exchange for any Securities cancelled as
provided in this Section, except as expressly permitted by this Indenture. All
cancelled Securities held by the Security Registrar, the Trustee or the
Authenticating Agent shall be disposed of as directed by a Company Order.

SECTION 310. COMPUTATION OF INTEREST.

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

                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

SECTION 401. SATISFACTION, DISCHARGE AND DEFEASANCE OF SECURITIES OF ANY SERIES.

exchange of the series of Securities, (ii) rights of Holders under Section 508
to receive payments of principal of and premium, if any, and interest on, the

of the Company to make mandatory sinking fund payments and (iv) the rights,
obligations and immunities of the Trustee hereunder) as it relates to such

       delivered (other than (i) Securities which have been destroyed, lost or
       stolen and which have been replaced or paid as provided in Section 306
       and (ii) Securities for whose payment money has theretofore been
       deposited in trust or segregated and held in trust by the Company and

       cancellation;

       payable under this Indenture in respect of the Securities of such series;
       and




                                      -31-




             (3) the Company has delivered to the Trustee an Officers'
       Certificate and an Opinion of Counsel, each stating that all conditions
       precedent herein provided for relating to the satisfaction of the entire
       indebtedness on all Securities of any such series and the discharge of
       the Indenture as it relates to such Securities have been complied with;
       or

          (b)(l) all Securities of such series not theretofore delivered to the
       Trustee for cancellation (i) have become due and payable, or (ii) will
       become due and payable at their Stated Maturity within one year, or (iii)
       are to be called for redemption within one year under arrangements
       satisfactory to the Trustee for the giving of notice of redemption by the

       been satisfied;

             (3) the conditions described in paragraphs (a)(2) and (a)(3) of
       this Section 401 have been satisfied; and

             (4) the Company has received an Opinion of Counsel to the effect
       that the satisfaction, discharge and defeasance contemplated by this
       Section 401 will not violate the then applicable rules of, or any related
       undertaking of the Company to, any nationally-recognized securities
       exchange on which Securities of that series are listed; or

          or before such 91st day, the Trustee shall promptly, upon satisfactory
          receipt of evidence of such failure, return such deposit to the
          Company; and

                   (3) the Company has delivered to the Trustee an Opinion of
          Counsel of a nationally-recognized independent tax counsel to the
          effect that Holders of the Securities of such series will not
          recognize income, gain or loss for Federal income tax purposes as a
          result of such deposit and the satisfaction, discharge and defeasance
          contemplated by this paragraph (c) of this Section 401 and will be

          subject to Federal income tax in the same amounts and in the same
          manner and at the same times as would have been the case if such
          deposit and defeasance had not occurred.

                                      -36-






     If an Event of Default described in Section 501(1), (2) or (7) with respect
to Securities of any series at the time Outstanding occurs and is continuing,
then in every such case the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Securities of that series may declare the
principal amount (or, if the Securities of that series are Original Issue
Discount Securities, such portion of the principal amount as may be specified in
the terms of that series) of all of the Securities of that 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 any such declarations such principal amount (or
specified amount) shall become immediately due and payable.

     If an Event of Default described in Section 501(3), (4), (5), (6) or (7)
occurs and is continuing, then in every such case the Trustee or the Holders of
not less than 25% in principal amount of the Outstanding Securities may declare
the principal amount (or, if any of the Outstanding Securities are Original

specified in the terms of those Original Issue Discount Securities) of all of
the Outstanding Securities to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become
immediately due and payable.

Trustee as hereinafter in this Article provided, the Holders of a majority in
principal amount of all Outstanding Securities or of the Outstanding Securities
of that series, as the case may be, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if (1) the
Company has paid or deposited with the Trustee a sum sufficient to pay

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

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

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

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



                                      -37-




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

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

SECTION 503. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

     The Company covenants that if

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

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

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

     If the Company fails 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 occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders 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.





                                      -38-




SECTION 504.  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 (and premium, if any) or
interest) shall be entitled and empowered, by intervention in such proceeding or
otherwise,

               (i) to file and prove a claim for the whole amount of principal
          (and premium, if any) and interest 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 the reasonable compensation, expenses,
          disbursements and advances of the Trustee, its agents and counsel) and
          of the Holders allowed in such judicial proceeding;

               (ii) to collect and receive any moneys or other property payable
          or deliverable on any such claims and to distribute the same; and

               (iii) unless prohibited by law or applicable regulations, to vote
          on behalf of the Holders in any election of a trustee in bankruptcy or
          other person performing similar functions;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607. 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, 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 except, as aforesaid, for the election of a trustee in bankruptcy or
other person performing similar functions.

SECTION 505.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

     All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities or 



                                      -49-






the production thereof in any proceeding relating thereto, and any such
proceeding instituted by the Trustee: shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Securities in respect of which such judgment has been
recovered.

SECTION 506.  APPLICATION OF MONEY COLLECTED.

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

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

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

          THIRD: The balance, if any, to the Person or Persons entitled thereto.

SECTION  507.  LIMITATION ON SUITS.

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

          (1) an Event of Default shall have occurred and be continuing and such
     Holder has previously given written notice to the Trustee of such
     continuing Event of Default with respect to the Securities of that series;

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




                                      -40-




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

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

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

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

SECTION 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND 
             INTEREST.

     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 Section 307)
interest 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 509.  RESTORATION OF RIGHTS AND REMEDIES.

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

SECTION 510.  RIGHTS AND REMEDIES CUMULATIVE.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
306, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders is intended to 




                                      -41-




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 511.  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 512. CONTROL BY HOLDERS.

     The Holders of a majority in principal amount of the Outstanding Securities
of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee, with respect to the Securities of
such series, PROVIDED that

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

          (2) subject to the provisions of Section 601, the Trustee shall have
     the right to decline to follow such direction if the Trustee shall
     determine that such direction would be unduly prejudicial to any Holders
     not joining in giving said direction or would involve the Trustee in any
     personal liability, and

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

SECTION 513. WAIVER OF PAST DEFAULTS. The Holders of not less than a majority in
principal amount of the Outstanding Securities of any series may on behalf of
the Holders of all the Securities of such series waive any past default
hereunder with respect to such series and its consequences, except a default

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




                                      -42-




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

     Upon any such waiver, such default shall cease to exist, and any Event 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 514.  UNDERTAKING FOR COSTS.

     All parties to this Indenture agree, and each Holder of any Security 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 principal
amount of the Outstanding Securities of any series, or to any suit instituted by
any Holder for the enforcement of the payment of the principal of (or premium,
if any) or interest on any 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 515. 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 has been enacted.




                                       -43



                                   ARTICLE SIX

                                   THE TRUSTEE

SECTION 601.  CERTAIN DUTIES AND RESPONSIBILITIES.

          (a) Except during the continuance of an Event of Default,

               (1) the Trustee undertakes to perform 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
          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 require meets
          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 has occurred and is continuing, the
     Trustee shall exercise such of the rights and powers vested in it by this
     Indenture, and use the same degree of care and skill in their exercise, as
     a prudent 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, suffered 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 series,
          determined as provided in Section 




                                      -44-



          512, 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 the Indenture with
          respect to the Securities of such series; and

               (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 602. NOTICE OF DEFAULTS.

     Within 90 days after the occurrence of any default hereunder with respect
to the Securities of any series, the Trustee shall transmit or cause to be
transmitted by mail to all Holders of Securities of such series, as their names
and addresses appear in the Security Register, notice of such default hereunder
known to the Trustee, unless such default shall have been cured or waived;
PROVIDED, HOWEVER, that, except in the case of a default in the payment of the
principal of (or premium, if any) or interest on any Security of such series,
the Trustee shall be protected in withholding such notice if and so long as the
board of directors, the executive committee or a trust committee of directors or
Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the interest of the Holders of Securities of such series;
and PROVIDED, FURTHER, that in the case of any default of the character
specified in Section 501(4) with respect to Securities of such series, no such
notice to Holders shall be given until at least 30 days after the occurrence
thereof. For the purpose of this Section, the term "default" means any event
which is, or after notice or lapse of time or both would become, an Event of
Default with respect to Securities of such series.

SECTION 603. CERTAIN RIGHTS OF TRUSTEE.

     Subject to the provisions of Section 601:

          (a) the Trustee may rely and shall be protected in acting or

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

          (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;

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

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

     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 be entitled to examine 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) the Trustee shall not be liable for any action taken, suffered or
     omitted by it in good faith and believed by it to be authorized or within
     the discretion or rights or powers conferred upon it by this Indenture.




                                      -46-




SECTION 604.  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

     The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee or any Authenticating Agent assumes no responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities. The Trustee or any
Authenticating Agent shall not be accountable for the use or application by the
Company of Securities or the proceeds thereof.

SECTION 605.  MAY HOLD SECURITIES.

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

SECTION 606.  MONEY HELD IN TRUST.

     Money held by the Trustee or any Paying Agent in trust hereunder need not
be segregated from other funds except to the extent required by law. The Trustee

SECTION 607.  COMPENSATION AND REIMBURSEMENT.

     The Company agrees

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

          (2) except as otherwise expressly provided herein, to reimburse the
     Trustee upon its request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustee in performance of its duties under
     or with respect to this Indenture (including the reasonable compensation
     and the expenses and disbursements of its agents and counsel), except any
     such expense, disbursement or advance as may be attributable to its
     misconduct, bad faith or negligence; and

          (3) to indemnify each of the Trustee, any predecessor trustee or their
     agents for, and to hold each of them harmless against, any loss, liability
     or expense incurred without negligence or bad faith on the part of the
     person seeking such 




                                      -47-



     indemnity, arising out of or in connection with the acceptance or
     administration of the trust or trusts or the performance of their duties
     hereunder, including the costs and expenses of defending themselves against
     any claim or liability in connection with the exercise or performance of
     any of their powers or duties hereunder.

     As security for the performance of the obligations of the Company under
this Section the Trustee shall have a claim prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (and premium, if any) or interest on
Securities.

SECTION 608.  DISQUALIFICATION; CONFLICTING INTERESTS.

          (a) If the Trustee has or shall acquire any conflicting interest, as
     defined in this Section, it shall, within 90 days after ascertaining that
     it has such conflicting interest, either eliminate such conflicting
     interest or resign in the manner and with the effect hereinafter specified
     in this Article.

          (b) In the event that the Trustee shall fail to comply with the
     provisions of Subsection (a) of this Section, the Trustee shall, within 10
     days after the expiration of such 90-day period, transmit or cause to be
     transmitted by mail to all Holders, as their names and addresses appear in
     the Security Register, notice of such failure.

          (c) For the purposes of this Section, the Trustee shall be deemed to
     have a conflicting interest, with respect to the Securities of any series,
     if

               (1) the Trustee is trustee under another indenture under which
          any other securities, or certificates of interest or participation in
          any other securities, of the Company are outstanding, unless such
          other indenture is a collateral trust indenture under which the only
          collateral consists of Securities issued under this Indenture,
          PROVIDED that there shall be excluded from the operation of this
          paragraph the indenture dated as of [________ __], [1999], between 
          the Company and Trustee pursuant to which the Company issued its 
          [___________________________________________] and this Indenture 
          with respect to the Securities of any series other than that series 
          or any indenture or indentures under which other securities, or 
          certificates of interest or participation in other securities, of 
          the Company are outstanding, if

                    (i) this Indenture and such other indenture or indentures
               are wholly unsecured and such other indenture or indentures are
               hereafter qualified under the Trust Indenture Act, unless the
               Commission shall have found and declared by order pursuant to




                                      -48-




               Section 305(b) or Section 307(c) of the Trust Indenture Act that
               differences exist between the provisions of this Indenture and
               the provisions of such other indenture or indentures which are so
               likely to involve a material conflict of interest as to make it
               necessary in the public interest or for the protection of
               investors to disqualify the Trustee from acting as such under
               this Indenture and such other indenture or indentures, or

                    (ii) the Company shall have sustained the burden of proving,
               on application to the Commission and after opportunity for
               hearing thereon, that trusteeship under this Indenture and such
               other indenture or indentures is not so likely to involve a
               material conflict of interest as to make it necessary in the
               public interest or for the protection of investors to disqualify
               the Trustee from acting as such under one of such indentures;

               (2) the Trustee or any of its directors or executive officers is
          an obligor upon the Securities or an underwriter for the Company;

               (3) the Trustee directly or indirectly controls or is directly or
          indirectly controlled by or is under direct or indirect common control
          with the Company or an underwriter for the Company;

               (4) the Trustee or any of its directors or executive officers is
          a director, officer, partner, employee, appointee or representative of
          the Company, or of an underwriter (other than the Trustee itself) for
          the Company who is currently engaged in the business of underwriting,
          except that (i) one individual may be a director or an executive
          officer, or both, of the Trustee and a director or an executive
          officer, or both, of the Company but may not be at the same time an
          executive officer of both the Trustee and the Company; (ii) if and so
          long as the number of directors of the Trustee in office is more than
          nine, one additional individual may be a director or an executive
          officer, or both, of the Trustee and a director of the Company; and
          (iii) the Trustee may be designated by the Company or by any
          underwriter for the Company to act in the capacity of transfer agent,
          registrar, custodian, paying agent, fiscal agent, escrow agent or
          depositary, or in any other similar capacity, or, subject to the
          provisions of paragraph (1) of this Subsection, to act as trustee,
          whether under an indenture or otherwise;

               (5) 10% or more of the voting securities of the Trustee is
          beneficially owned either by the Company or by any director, partner
          or 




                                      -49-





          executive officer thereof, or 20% or more of such voting securities is
          beneficially owned, collectively, by any two or more of such persons;
          or 10% or more of the voting securities of the Trustee is beneficially
          owned either by an underwriter for the Company or by any director,
          partner or executive officer thereof, or is beneficially owned,
          collectively, by any two or more such persons;

               (6) the Trustee is the beneficial owner of, or holds as
          collateral security for an obligation which is in default (as
          hereinafter in this Subsection defined), (i) 5% or more of the voting
          securities, or 10% or more of any other class of security, of the
          Company not including the Securities issued under this Indenture and
          securities issued under any other indenture under which the Trustee is
          also trustee, or (ii) 10% or more of any class of security of an
          underwriter for the Company;

               (7) the Trustee is the beneficial owner of, or holds as
          collateral security for an obligation which is in default (as
          hereinafter in this Subsection defined), 5% or more of the voting
          securities of any person who, to the knowledge of the Trustee, owns
          10% or more of the voting securities of, or controls directly if or
          indirectly or is under direct or indirect common control with, the
          Company;

               (8) the Trustee is the beneficial owner of, or holds as
          collateral security for an obligation which is in default (as
          hereinafter in this Subsection defined), 10% or more of any class of
          security of any person who, to the knowledge of the Trustee, owns 50%
          or more of the voting securities of the Company; or

               (9) the Trustee owns, on May 15 in any calendar year, in the
          capacity of executor, administrator, testamentary or inter vivos
          trustee, guardian, committee or conservator, or in any other similar
          capacity, an aggregate of 25% or more of the voting securities, or of
          any class of security, of any person, the beneficial ownership of a
          specified percentage of which would have constituted a conflicting
          interest under paragraph (6), (7) or (8) of this Subsection. As to any
          such securities of which the Trustee acquired ownership through
          becoming executor, administrator or testamentary trustee of an estate
          which included them, the provisions of the preceding sentence shall
          not apply, for a period of two years from the date of such
          acquisition, to the extent that such securities included in such
          estate do not exceed 25% of such voting securities or 25% of any such
          class of security. Promptly after May 15 in each calendar year, the
          Trustee shall make a check of its holdings of such securities in any
          of the




                                      -50-





          above-mentioned capacities as of such May 15. lf the Company fails to
          make payment in full of the principal of (or premium, if any) or
          interest on any of the Securities when and as the same becomes due and
          payable, and such failure continues for 30 days thereafter, the
          Trustee shall make a prompt check of its holdings of such securities
          in any of the above-mentioned capacities as of the date of the
          expiration of such 30-day period, and after such date, notwithstanding
          the foregoing provisions of this paragraph, all such securities so
          held by the Trustee, with sole or joint control over such securities
          vested in it, shall, but only so long as such failure shall continue,
          be considered as though beneficially owned by the Trustee for the
          purposes of paragraphs (6), (7) and (8) of this Subsection.

          The specification of percentages in paragraphs (5) to (9), inclusive,
     of this Subsection shall not be construed as indicating that the ownership
     of such percentages of the securities of a person is or is not necessary or
     sufficient to constitute direct or indirect control for the purposes of
     paragraph (3) or (7) of this Subsection.

     For the purposes of paragraphs (6), (7), (8) and (9) of this Subsection
only, (i) the terms "security" and "securities" shall include only such
securities as are generally known as corporate securities, but shall not include
any note or other evidence of indebtedness issued to evidence an obligation to
repay moneys lent to a person by one or more banks, trust companies or banking
firms, or any certificate of interest or participation in any such note or
evidence of indebtedness; (ii) an obligation shall be deemed to be "in default"
when a default in payment of principal shall have continued for 30 days or more
and shall not have been cured; and (iii) the Trustee shall not be deemed to be
the owner or holder of (A) any security which it holds as collateral security,
as trustee or otherwise, for an obligation which is not in default as defined in
clause (ii) above, or (B) any security which it holds as collateral security
under this Indenture, irrespective of any default hereunder, or (C) any security
which it holds as agent for collection, or as custodian, escrow agent or
depositary, or in any similar representative capacity.

          (d) For the purposes of this Section:

               (1) The term "underwriter," when used with reference to the
          Company, means every person who, within three years prior to the time
          as of which the determination is made, has purchased from the Company
          with a view to, or has offered or sold for the Company in connection
          with, the distribution of any security of the Company outstanding at
          such time, or has participated or has had a direct or indirect
          participation in any such undertaking, or has participated or has had
          a participation in the direct or indirect underwriting of any such
          undertaking, but such term shall not



                                      -51-





          include a person whose interest was limited to a commission from an
          underwriter or dealer not in excess of the usual and customary
          distributors' or sellers' commission.

               (2) The term "director" means any director of a corporation or

          partnership, an association, a joint-stock company, a trust, an
          unincorporated organization or a government or political subdivision
          thereof. As used in this paragraph, the term "trust" shall include
          only a trust where the interest or interests of the beneficiary or
          beneficiaries are evidenced by a security.

               (4) The term "voting security" means any security presently
          entitling the owner or holder thereof to vote in the direction or
          management of the affairs of a person, or any security issued under or
          pursuant to any trust, agreement or arrangement whereby a trustee or
          trustees or agent or agents for the owner or holder of such security
          are presently entitled to vote in the direction or management of the
          affairs of a person.

               (5) The term "Company" means an obligor upon the Securities.

               (6) The term "executive officer" means the president, every vice
          president, every trust officer, the cashier, the secretary and the
          treasurer of a corporation, and any individual customarily performing
          similar functions with respect to any organization whether
          incorporated or unincorporated, but shall not include the chairman of
          the board of directors.

          (e) The percentages of voting securities and other securities
     specified in this Section shall be calculated in accordance with the
     following provisions:

               (1) A specified percentage of the voting securities of the
          Trustee, the Company or any other person referred to in this Section
          (each of whom is referred to as a "person" in this paragraph) means
          such amount of the outstanding voting securities of such person as
          entitles the holder or holders thereof to cast such specified
          percentage of the aggregate votes which the holders of all the
          outstanding voting securities of such person are entitled to cast in
          the direction or management of the affairs of such person.




                                      -52-





               (2) A specified percentage of a class of securities of a person
          means such percentage of the aggregate amount of securities of the
          class outstanding.

               (3) The term "amount," when used in regard to securities, means
          the principal amount if relating to evidences of indebtedness, the
          number of shares if relating to capital shares and the number of units
          if relating to any other kind of security.

               (4) The term "outstanding" means issued and not held by or for
          the account of the issuer. The following securities shall not be
          deemed outstanding within the meaning of this definition:

                    (i) securities of an issuer held in a sinking fund relating
               to securities of the issuer of the same class;

                    (ii) securities of an issuer held in a sinking fund relating
               to another class of securities of the issuer, if the obligation
               evidenced by such other class of securities is not in default as
               to principal or interest or otherwise;

                    (iii) securities pledged by the issuer thereof as security
               for an obligation of the issuer not in default as to principal or
               interest or otherwise; and

                    (iv) securities held in escrow if placed in escrow by the
               issuer thereof;

               (5) A security shall be deemed to be of the same class as another
          security if both securities confer upon the holder or holders thereof
          substantially the same rights and privileges; PROVIDED, HOWEVER, that,
          in the case of secured evidences of indebtedness, all of which are
          issued under a single indenture, differences in the interest rates or
          maturity dates of various series thereof shall not be deemed
          sufficient to constitute such series different classes and PROVIDED,
          FURTHER, that, in the case of unsecured evidences of indebtedness,
          differences in the interest rates or maturity dates thereof shall not
          be deemed sufficient to constitute them securities of different
          classes, whether or not they are issued under a single indenture.

SECTION 609.  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.



                                      -53-




     There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least $100,000,000 subject to supervision or examination by federal, state
or District of Columbia authority. If such corporation 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 corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

SECTION 610. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

          (a) No resignation or removal of the Trustee and no appointment of a
     successor Trustee pursuant to this Article shall become effective until the
     acceptance of appointment by the successor Trustee under Section 611.

          (b) The Trustee may resign at any time by giving written notice
     thereof to the Company. If an instrument of acceptance by a successor
     Trustee shall not have been delivered to the Trustee within 30 days after
     the giving of such notice of resignation, the resigning Trustee may
     petition any court of competent jurisdiction for the appointment of a
     successor Trustee.

          (c) The Trustee may be removed at any time by Act of the Holders of a
     majority in principal amount of the Outstanding Securities, delivered to
     the Trustee and to the Company.

          (d) If at any time:

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

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

               (3) the Trustee shall become incapable of acting or shall be
          adjudged a bankrupt or insolvent or a receiver of the Trustee or of
          its property shall be appointed or any public officer shall take
          charge or 



                                      -54-




          control of the Trustee or of its property or affairs for the purpose
          of rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 514, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

          (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,
     the Company, by a Board Resolution, shall promptly appoint a successor
     Trustee. If, within one year after such resignation, removal or
     incapability, or the occurrence of such vacancy, a successor Trustee shall
     be appointed by Act of the Holders of a majority in principal amount of the
     Outstanding Securities delivered to the Company and the retiring Trustee,
     the successor Trustee so appointed shall, forthwith upon its acceptance of
     such appointment, become the successor Trustee and supersede the successor
     Trustee appointed by the Company. If no successor Trustee shall have been
     so appointed by the Company or the Holders and accepted appointment in the
     manner hereinafter provided, any Holder who has been a bona fide Holder of
     a Security for at least six months may, on behalf of himself and all others
     similarly situated, subject to Section 514, petition any court of competent
     jurisdiction for the appointment of a successor Trustee.

          (f) The Company shall give notice of each resignation and each removal
     of the Trustee and each appointment of a successor Trustee by mailing
     written notice of such event by first-class mail, postage prepaid, to all
     Holders as their names and addresses appear in the Security Register. Each
     notice shall include the name of the successor Trustee and the address of
     its Corporate Trust Office.

SECTION 611.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

     Every successor Trustee appointed hereunder shall execute, acknowledge and
deliver to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder, subject nevertheless to its prior claim, if any, provided for
in Section 



                                      -55-





607. Upon request of any such successor Trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all such rights, powers and trusts.

     No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article.

SECTION 612. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

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

SECTION 613.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

          (a) Subject to Subsection (b) of this Section, if the Trustee shall be
     or shall become a creditor, directly or indirectly, secured or unsecured,
     of the Company within four months prior to a default, as defined in
     Subsection (c) of this Section, or subsequent to such a default, then,
     unless and until such default shall be cured, the Trustee shall set apart
     and hold in a special account for the benefit of the Trustee individually,
     the Holders of the Securities and the holders of other indenture
     securities, as defined in Subsection (c) of this Section:

               (1) an amount equal to any and all reductions in the amount due
          and owing upon any claim as such creditor in respect of principal or
          interest, effected after the beginning of such four-month period and
          valid as against the Company and its other creditors, except any such
          reduction resulting from the receipt or disposition of any property
          described in paragraph (2) of this Subsection, or from the exercise of
          any right of set-off which the Trustee could have exercised if a
          petition in bankruptcy had been filed by or against the Company upon
          the date of such default; and

               (2) all property received by the Trustee in respect of any claims
          as such creditor, either as security therefor, or in satisfaction or
          composition 



                                      -56-






          thereof, or otherwise, after the beginning of such four-month period,
          or an amount equal to the proceeds of any such property, if disposed
          of, SUBJECT, HOWEVER, to the rights, if any, of the Company and its
          other creditors in such property or such proceeds.

               Nothing herein contained, however, shall affect the right of the
          Trustee:

                    (A) to retain for its own account (i) payments made on
               account of any such claim by any Person (other than the Company)
               who is liable thereon, and (ii) the proceeds of the bona fide
               sale of any such claim by the Trustee to a third Person, and
               (iii) distributions made in cash, securities or other property in
               respect of claims filed against the Company in bankruptcy or
               receivership or in proceedings for reorganization pursuant to the
               Federal Bankruptcy Act or applicable state law;

                    (B) to realize, for its own account, upon any property held
               by it as security for any such claim, if such property was so
               held prior to the beginning of such four-month period;

                    (C) to realize, for its own account, but only to the extent
               of the claim hereinafter mentioned, upon any property held by it
               as security for any such claim, if such claim was created after
               the beginning of such four-month period and such property was
               received as security therefor simultaneously with the creation
               thereof, and if the Trustee shall sustain the burden of proving
               that at the time such property was so received the Trustee had no
               reasonable cause to believe that a default, as defined in
               Subsection (c) of this Section, would occur within four months;
               or

                    (D) to receive payment on any claim referred to in paragraph
               (B) or (C), against the release of any property held as security
               for such claim as provided in paragraph (B) or (C), as the case
               may be, to the extent of the fair value of such property.

          For the purposes of paragraphs (B), (C) and (D), property substituted
     after the beginning of such four-month period for property held as security
     at the time of such substitution shall, to the extent of the fair value of
     the property released, have the same status as the property released, and,
     to the extent that any claim referred to in any of such paragraphs is
     created in renewal of or in substitution for or for the 



                                      -57-




     purpose of repaying or refunding any pre-existing claim of the Trustee as
     such creditor, such claim shall have the same status as such pre-existing
     claim.

          If the Trustee shall be required to account, the funds and property
     held in such special account and the proceeds thereof shall be apportioned
     among the Trustee, the Holders and the holders of other indenture
     securities in such manner that the Trustee, the Holders and the holders of
     other indenture securities realize, as a result of payments from such
     special account and payments of dividends on claims filed against the
     Company in bankruptcy or receivership or in proceedings for reorganization
     pursuant to the Federal Bankruptcy Act or applicable state law, the same
     percentage of their respective claims, figured before crediting to the
     claim of the Trustee anything on account of the receipt by it from the
     Company of the funds and property in such special account and before
     crediting to the respective claims of the Trustee and the Holders and the
     holders of other indenture securities dividends on claims filed against the
     Company in bankruptcy or receivership or in proceedings for reorganization
     pursuant to the Federal Bankruptcy Act or applicable state law, but after
     crediting thereon receipts on account of the indebtedness represented by
     their respective claims from all sources other than from such dividends and
     from the funds and property so held in such special account. As used in
     this paragraph, with respect to any claim, the term "dividends" shall
     include any distribution with respect to such claim, in bankruptcy or
     receivership or proceedings for reorganization pursuant to the Federal
     Bankruptcy Act or applicable state law, whether such distribution is made
     in cash, securities or other property, but shall not include any such
     distribution with respect to the secured portion, if any, of such claim.
     The court in which such bankruptcy, receivership or proceedings for
     reorganization is pending shall have jurisdiction (i) to apportion among
     the Trustee, the Holders and the holders of other indenture securities, in
     accordance with the provisions of this paragraph, the funds and property
     held in such special account and proceeds thereof, or (ii) in lieu of such
     apportionment, in whole or in part, to give to the provisions of this
     paragraph due consideration in determining the fairness of the
     distributions to be made to the Trustee and the Holders and the holders of
     other indenture securities with respect to their respective claims, in
     which event it shall not be necessary to liquidate or to appraise the value
     of any securities or other property held in such special account or as
     security for any such claim, or to make a specific allocation of such
     distributions as between the secured and unsecured portions of such claims,
     or otherwise to apply the provisions of this paragraph as a mathematical
     formula.

          Any Trustee which has resigned or been removed after the beginning of
     such four-month period shall be subject to the provisions of this
     Subsection as though such resignation or removal had not occurred. If any
     Trustee has resigned or been removed prior to the beginning of such
     four-month period, it shall be subject to the provisions of this Subsection
     if and only if the following conditions exist:


                                      -58-





               (i) the receipt of property or reduction of claim, which would
          have given rise to the obligation to account, if such Trustee had
          continued as Trustee, occurred after the beginning of such four-month
          period; and

               (ii) such receipt of property or reduction of claim occurred
          within four months after such resignation or removal.

          (b) There shall be excluded from the operation of Subsection (a) of
     this Section a creditor relationship arising from:

               (1) the ownership or acquisition of securities issued under any
          indenture, or any security or securities having a maturity of one year
          or more at the time of acquisition by the Trustee;

               (2) advances authorized by a receivership or bankruptcy court of
          competent jurisdiction or by this Indenture, for the purpose of
          preserving any property which shall at any time be subject to the lien
          of this Indenture or of discharging tax liens or other prior liens or
          encumbrances thereon, if notice of such advances and of the
          circumstances surrounding the making thereof is given to the Holders
          at the time and in the manner provided in this Indenture;

               (3) disbursements made in the ordinary course of business in the
          capacity of trustee under an indenture, transfer agent, registrar,
          custodian, paying agent, fiscal agent, escrow agent or depositary, or
          other similar capacity;

               (4) an indebtedness created as a result of services rendered or
          premises rented; or an indebtedness created as a result of goods or
          securities sold in a cash transaction, as defined in Subsection (c) of
          this Section;

               (5) the ownership of stock or of other securities of a
          corporation organized under the provisions of Section 25(a) of the
          Federal Reserve Act, as amended, which is directly or indirectly a
          creditor of the Company; and

               (6) the acquisition, ownership, acceptance or negotiation of any
          drafts, bills of exchange, acceptances or obligations which fall
          within the classification of self-liquidating paper, as defined in
          Subsection (c) of this Section.

          (c) For the purposes of this Section only:



                                      -59-



               (1) the term "default" means any failure to make payment in full
          of the principal of or interest on any of the Securities or upon the
          other indenture securities when and as such principal or interest
          becomes due and payable;

               (2) the term "other indenture securities" means securities upon
          which the Company is an obligor outstanding under any other indenture
          (i) under which the Trustee is also trustee, (ii) which contains
          provisions substantially similar to the provisions of this Section,
          and (iii) under which a default exists at the time of the
          apportionment of the funds and property held in such special account;

               (3) the term "cash transaction" means any transaction in which
          full payment for goods or securities sold is made within seven days
          after delivery of the goods or securities in currency or in checks or
          other orders drawn upon banks or bankers and payable upon demand;

               (4) the term "self-liquidating paper" means any draft, bill of

          or merchandise and which is secured by documents evidencing title to,
          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;

               (5) the term "Company" means any obligor upon the Securities; and

               (6) the term "Federal Bankruptcy Act" means the Bankruptcy Act or

SECTION  614.  APPOINTMENT OF AUTHENTICATING AGENT.

     At any time when any of the Securities remain Outstanding, the Trustee may
appoint an Authenticating Agent or Agents with respect to one or more series of
Securities which shall be authorized to act on behalf and subject to the
direction of the Trustee to authenticate Securities of such series issued upon
exchange, registration of transfer or partial redemption thereof and to cancel
Securities pursuant to Section 309, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and 



                                      -60-



obligatory for all purposes as if authenticated by the Trustee hereunder. The
Trustee hereby initially appoints the Idaho First National Bank as an
Authenticating Agent in Boise, Idaho. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any state thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by federal, state or District of Columbia
authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

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

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or case at any time such Authenticating
Agent shall cease to be eligible in accordance with the provisions of this
Section, the Trustee may appoint a successor Authenticating Agent which shall be
acceptable to the Company and shall mail or cause to be mailed written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register. 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.


                                      -61-



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

     While an appointment with respect to one or more series is in effect
pursuant to this Section, the Securities of such series may have endorsed
thereon an alternate certificate of authentication in the following form:

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

                                  ARTICLE SEVEN

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

SECTION 701. COMPANY TO FURNISH TRUSTEE NAMES AND ADDRESSES OF HOLDERS.

     The Company will furnish or cause to be furnished to the Trustee

          (a) not later than 15 days after each Regular Record Date, in the case
     of Securities that are interest bearing, and on each date determined
     pursuant to Section 301 in the case of Securities that are not interest
     bearing, a list, in such form as the Trustee may reasonably require, of the
     names and addresses of the Holders of the Securities as of such Regular
     Record Date or as of such other date, as the case may be, and


                                      -62-





          (b) at such other times as the Trustee may request in writing, within
     30 days after the receipt by the Company of any such request, a list of
     similar form and content as of a date not more than 15 days prior to the
     time such list is furnished;

EXCLUDING from any such list names and addresses received by the Trustee in its
capacity as Security Registrar, if so acting.

SECTION 702.  PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS.

          (a) The Trustee shall preserve, in as current a form as is reasonably
     practicable, the names and addresses of Holders of each series of
     Securities contained in the most recent list furnished to the Trustee as
     provided in Section 701 and the names and addresses of Holders received by
     the Trustee in its capacity as Security Registrar, if so acting. The
     Trustee may destroy any list furnished to it as provided in Section 701
     upon receipt of a new list so furnished.

          (b) If three or more Holders (herein referred to as "applicants")
     apply in writing to the Trustee, and furnish to the Trustee reasonable
     proof that each such applicant has owned a Security for a period of at
     least six months preceding the date of such application, and such
     application states that the applicants desire to communicate with other
     Holders with respect to their rights under this Indenture or under the
     Securities and is accompanied by a copy of the form of proxy or other
     communication which such applicants propose to transmit, then the Trustee
     shall, within five business days after the receipt of such application, at
     its election, either

               (i) afford such applicants access to the information preserved at
          the time by the Trustee in accordance with Section 702(a), or

               (ii) inform such applicants as to the approximate number of
          Holders whose names and addresses appear in the information preserved
          at the time by the Trustee in accordance with Section 702(a), and as
          to the approximate cost of mailing to such Holders the form of proxy
          or other communication, if any, specified in such application.

          If the Trustee shall elect not to afford such applicants access to
     such information, the Trustee shall, upon the written request of such
     applicants, mail, or cause to be mailed, to each Holder whose name and
     address appear in the information preserved at the time by the Trustee in
     accordance with Section 702(a) a copy of the form of proxy or other
     communication which is specified in such request, with reasonable
     promptness after a tender to the Trustee of the material to be mailed and
     of payment, or provision for the payment, of the reasonable expenses 



                                      -63-





     of mailing, unless within five days after such tender the Trustee shall
     mail, or cause to be mailed, to such applicants and file with the
     Commission, together with a copy of the material to be mailed, a written
     statement to the effect that, in the opinion of the Trustee, such mailing
     would be contrary to the best interest of the Holders or would be in
     violation of applicable law. Such written statement shall specify the basis
     of such opinion. If the Commission, after opportunity for a hearing upon
     the objections specified in the written statement so filed, shall enter an
     order refusing to sustain any of such objections or if, after the entry of
     an order sustaining one or more of such objections, the Commission shall
     find, after notice and opportunity for hearing, that all the objections so
     sustained have been met and shall enter an order so declaring, the Trustee
     shall mail, or cause to be mailed, copies of such material to all such
     Holders with reasonable promptness after the entry of such order and the
     renewal of such tender; otherwise the Trustee shall be relieved of any
     obligation or duty to such applicants respecting their application.

          (c) Every Holder by receiving and holding the same, agrees with the
     Company and the Trustee that neither the Company nor the Trustee nor any
     agent of either of them shall be held accountable by reason of the
     disclosure of any such information as to the names and addresses of the
     Holders in accordance with Section 702(b), regardless of the source from
     which such information was derived, and that the Trustee shall not be held
     accountable by reason of mailing any material pursuant to a request made
     under Section 702(b).

SECTION 703.  REPORTS BY TRUSTEE.

          (a) Within 60 days after May 15 of each year commencing with the year
     [____], the Trustee shall transmit by mail to all Holders, as their names 
     and addresses appear in the Security Register, a brief report dated as of 
     such date with respect to:

               (1) its eligibility under Section 609 and its qualifications
          under Section 608, or in lieu thereof, if to the best of its knowledge
          it has continued to be eligible and qualified under said Sections, a
          written statement to such effect;

               (2) the character and amount of any advances (and if the Trustee
          elects so to state, the circumstances surrounding the making thereof)
          made by the Trustee (as such) which remain unpaid on the date of such
          report, and for the reimbursement of which it asserts or may assert a
          claim or charge, prior to that of the Securities, on any property or
          funds held or collected by it as Trustee, except that the Trustee
          shall not be required (but may elect) to report such advances if such
          advances so remaining unpaid aggregate not more than 1/2 of 1% of the
          principal amount of the Securities Outstanding on the date of such
          report;


                                      -64-





               (3) the amount, interest rate and maturity date of all other
          indebtedness owing by the Company (or by any other obligor on the
          Securities) to the Trustee in its individual capacity, on the date of
          such report, with a brief description of any property held as
          collateral security therefor, except an indebtedness based upon a
          creditor relationship arising in any manner described in Section
          613(b)(2), (3), (4) or (6);

               (4) the property and funds, if any, physically in the possession
          of the Trustee as such on the date of such report;

               (5) any additional issue of Securities which the Trustee has not
          previously reported; and

               (6) any action taken by the Trustee in the performance of its
          duties hereunder which it has not previously reported and which in its
          opinion materially affects the Securities, except action in respect of
          a default, notice of which has been or is to be withheld by the
          Trustee in accordance with Section 602.

          (b) The Trustee shall transmit, or cause to be transmitted, by mail to
     all Holders, as their names and addresses appear in the Security Register,
     a brief report with respect to the character and amount of any advances
     (and if the Trustee elects so to state, the circumstances surrounding the
     making thereof) made by the Trustee (as such) since the date of the last
     report transmitted pursuant to Subsection (a) of this Section (or if no
     such report has yet been so transmitted, since the date of execution of
     this instrument) for the reimbursement of which it asserts or may assert a
     claim or charge, prior to that of the Securities, on property or funds held
     or collected by it as Trustee and which it has not previously reported
     pursuant to this Subsection, except that the Trustee shall not be required
     (but may elect) to report such advances if such advances remaining unpaid
     at any time aggregate 10% or less of the principal amount of the Securities
     Outstanding at such time, such report to be transmitted within 90 days
     after such time.

          (c) A copy of each such report shall, at the time of such transmission
     to Holders, be filed by the Trustee with each stock exchange upon which any
     Securities are listed, with the Commission and with the Company. The
     Company will notify the Trustee when any Securities are listed on any stock
     exchange.

SECTION 704.  REPORTS BY COMPANY.

     The Company shall:


                                      -65-





               (1 ) file with the Trustee, within 15 days after the Company is
          required to file the same with the Commission, copies of the annual
          reports and of the information, documents and other reports (or copies
          of such portions of any of the foregoing as the Commission may from
          time to time by rules and regulations prescribe) which the Company may

     and with or without interest coupons; or

          (5) to change or eliminate any of the provisions of this Indenture,
     PROVIDED that any such change or elimination shall become effective only

     of such provision; or

          (6) to establish the form or terms of Securities of any series as

principal amount of the Outstanding Securities of each series affected by such
supplemental indenture, 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 or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; PROVIDED, HOWEVER,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby,

     of redemption, on or after the Redemption Date), or reduce the amount of
     the principal of an Original Issue Discount Security that would be due and
     payable upon a declaration of acceleration of the Maturity thereof pursuant

     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 which modifies the
rights of the Holders of Securities of such series 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.

     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.

Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture and that such supplemental indenture,
when executed and delivered by the Company, will constitute a valid and binding
obligation of the Company in accordance with its terms. The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.


                                      -69-

any supplemental indenture pursuant to this Article may, and shall if required
by 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 so modified as to conform, in the opinion of the

                                    COVENANTS

SECTION 1001.  PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

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

SECTION 1002.  MAINTENANCE OF OFFICE OR AGENCY.

     The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location and any change in the location of any such office or agency. If at any
time the Company shall fail to maintain any such required office 


                                      -70-





or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

     Until changed by the Company in accordance with this Indenture, the Company
will maintain a Place of Payment at the Corporate Trust Office.

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

SECTION 1003.  MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

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

     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, prior to each due date of the principal of (and premium, if
any) or interest on any Securities of that series, deposit with a Paying Agent a
sum sufficient to pay the principal (and premium, if any) 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 will promptly notify the Trustee of its failure so
to act.

     The Company will cause each Paying Agent for any series of Securities other
than the Trustee to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee, subject to the provisions of
this Section, that such Paying Agent will:

          (1) hold all sums held by it for the payment of the principal of (and
     premium, if any) or interest on Securities of that series in trust for the
     benefit of 



                                      -71-





     the Persons entitled thereto until such sums shall be paid to such Persons
     or otherwise disposed of as herein provided;

          (2) give the Trustee notice of any default by the Company (or any
     other obligor upon the Securities of that series) in the making of any
     payment of principal (and premium, if any) or interest on the Securities of
     that series; and

          (3) 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.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

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

SECTION 1004.  STATEMENT AS TO COMPLIANCE.

     The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year, a written statement signed by the Chairman of the Board, the
President or a Vice President and by the Treasurer, an Assistant Treasurer, the
Controller or an Assistant Controller of the Company, stating, as to each signer
thereof, that:

     performance under this Indenture has been made under his supervision, and

          (2) to the best of his knowledge, based on such review, the Company is
     not in default in the fulfillment of any of its obligations under this
     Indenture, or specifying each such default known to him and the nature and
     status thereof.

things necessary to preserve and keep in full force and effect its corporate
existence.

     The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Sections 1002 to 1005, inclusive, with
respect to the Securities of any series, if before the time for such compliance
the Holders of at least a majority in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such term,
provision or condition, but no such waiver shall extend to or affect such term,
provision or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company and the duties of
the Trustee in respect of any such term, provision or condition shall remain in
full force and effect.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

SECTION 1101. APPLICABILITY OF ARTICLE.

accordance with this Article.

SECTION 1102.  ELECTION TO REDEEM; NOTICE TO TRUSTEE.

     In case of any redemption at the election of the Company of less than all
the Securities of any series, the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Securities of such series to be redeemed. In the case of
any redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in 



                                      -73-





this Indenture, the Company shall furnish the Trustee with an Officers'
Certificate evidencing compliance with such restrictions.

SECTION 1103. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

     If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected prior to the Redemption
Date by the Trustee or the Security Registrar with the approval of the Trustee,
from the Outstanding Securities of such series not previously called for
redemption, by such method as the Trustee or the Security Registrar shall deem
fair and appropriate and which may provide for the selection for redemption of
portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum authorized denomination
for Securities of that series.

     The party selecting the Securities to be redeemed shall promptly notify the
parties to this Indenture in writing of the Securities selected for redemption
and, in the case of any Securities selected for partial redemption, 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 1104.  NOTICE OF REDEMPTION.

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

     All notices of redemption shall state:

          (1) the Redemption Date,

          (2) the Redemption Price and accrued interest, if any, to the
     Redemption Date,

          (3) if less than all the Outstanding Securities of any series are to
     be redeemed, the identification (and, in the case of partial redemption,
     the principal amounts) of the particular Securities to be redeemed,


                                      -74-




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

          (5) the place or places where such Securities are to be surrendered
     for payment of the Redemption Price and accrued interest, and

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

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

     Any notice which is mailed in the manner herein provided shall be presumed
conclusively to have been duly given, whether or not the Holder receives such
notice; and failure duly to give such notice by mail, or any defect in such
notice, to the Holder of any Security designated for redemption as a whole or in
part shall not affect the validity of the proceedings for the redemption of any
other Security.

SECTION 1105. DEPOSIT OF REDEMPTION PRICE.

     Prior to the opening of business on any Redemption Date, the Company shall
deposit with the Trustee or with a Paying Agent (or, if the Company is acting as
its own Paying Agent, segregate and hold in trust as provided in Section 1003)
an amount of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date. In the event of any failure on
the part of the Company to deposit such money prior to any Redemption Date, the
Trustee shall not use any monies or U.S. Government Obligations deposited with
it pursuant to Sections 401 or 402 for the payment of any Redemption Price,
unless originally deposited for such purpose.

SECTION 1106.  SECURITIES PAYABLE ON REDEMPTION DATE.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified plus accrued interest, and from and after
such date (unless the Company shall default in the payment of the Redemption
Price and accrued interest) such Securities-shall cease to bear interest. Upon
surrender of any such Security for redemption in accordance with said notice,
such Security shall be paid by the Company at the Redemption Price, together
with accrued interest to the Redemption Date; PROVIDED, HOWEVER, that
installments of interest whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Securities, or one or more
Predecessor Securities, registered as such at the close of business on the
relevant Regular 



                                      -75-





Record Date or Special Record Date according to their terms and the provisions
of Section 307.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate prescribed therefor in the
Security.

SECTION 1107.  SECURITIES REDEEMED IN PART.

     Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company, the Trustee and the Security Registrar duly executed by, the Holder
thereof or his attorney duly authorized in writing), and the Company shall
execute, and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Security or Securities of the same
series, of any authorized denomination as requested by such Holder, in aggregate
principal amount equal to and in exchange for the unredeemed portion of the
principal of the Security so surrendered; PROVIDED, that if a Global Security is
so surrendered, such new Security so issued shall be a new Global Security in a
denomination equal to the unredeemed portion of the principal of the Global
Security so surrendered.

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

Section 1202.  SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.


                                      -76-




     The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption) and (2) may apply as a credit Securities
of a series which have been 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 any sinking fund payment with respect
to the Securities of such series required to be made pursuant to the terms of
such Securities as provided for by the terms of such series; PROVIDED that such
Securities have not been previously so credited. Such Securities 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 sinking fund payment shall be reduced accordingly.

SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND.

     Not less than 90 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202 and will also deliver to the Trustee any Securities to
be so delivered. Not less than 60 days before each such sinking fund payment
date the Trustee shall select or cause to be selected the Securities to be
redeemed upon such sinking fund payment date in the manner specified in Section
1103 and not less than 30 days before each sinking fund payment date cause
notice of the redemption thereof to be given in the name of and at the expense
of the Company in the manner provided in Section 1104. Such notice having been
duly given, the redemption of such Securities shall be made upon the terms and
in the manner stated in Sections 1106 and 1107.

hereby expressly made subordinate and subject in right of payment to the prior
payment in full of all Senior Indebtedness (whether outstanding on the date
hereof or hereafter created, incurred, assumed or guaranteed), and that the
subordination is for the benefit of the holders of Senior Indebtedness and that
no payment on account of principal of, premium, if any, or interest on the
Securities and no acquisition of, or payment on account of any sinking fund for,
the Securities may be made unless full payment of all amounts then due for
principal, premium, if any, and interest then due on all Senior Indebtedness by
reason of the maturity thereof (by lapse of time, 



                                      -77-

manner satisfactory to the holders of such Senior Indebtedness.


SECTION 1302.  PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.

     Upon any distribution of the Company's assets in connection with any
dissolution, winding up, liquidation or reorganization of the Company, whether
voluntary or involuntary, in bankruptcy, insolvency or receivership proceedings
(each such event, if any, herein sometimes referred to as a "Proceeding"), or
upon an assignment for the benefit of creditors or otherwise: (i) all Senior
Indebtedness (including without limitation all interest accruing on or after the
filing of any petition in bankruptcy relating to the Company at the relevant
contractual rate, whether or not such claim for post-petition interest is
allowed in such Proceeding) must be paid in full in cash before the Holders of
the Securities are entitled to any payments or distributions of any kind or
character (including any payment or distribution which may be payable or
deliverable by reason of the payment of any other Debt of the Company (including
the Securities) subordinated to the payment of the Securities), and (ii) any
payment or distribution of the Company's assets of any kind or character,
whether in cash, securities or other property, which would otherwise (but for
these subordination provisions) be payable or deliverable in respect of the
Securities shall be paid or delivered directly to the holders of such Senior
Indebtedness (or their representative or trustee) in accordance with the
priorities then existing among such holders until all Senior Indebtedness shall
have been paid in full in cash before any payment or distribution is made to the
Holders of the Securities.

     In the event that notwithstanding the subordination provisions set forth
herein, any payment or distribution of assets of any kind or character is made
on the Securities at a time when the respective payment is not permitted to be
made as a result of the subordination provisions described above and before all
Senior Indebtedness is paid in full in cash, the Trustee or the holders of the
Securities receiving such payment will be required to pay over such payment or
distribution to the holders of such Senior Indebtedness.

     For the purposes of this Article only, the words "any payment or
distribution of any kind or character" shall not be deemed to include shares of
stock of the Company as reorganized or readjusted, or securities of the Company
or any other corporation provided for by a plan of reorganization or
readjustment which securities are subordinated in right of payment to all then
outstanding Senior Indebtedness to substantially the same extent as the
Securities are so subordinated as provided in this Article. The consolidation of
the Company with, or the merger of the Company into, another Person or the
liquidation or dissolution of the Company following the sale of all or
substantially all of its properties and assets as an entirety to another Person
upon the terms and conditions set forth in 


                                      -78-




Article 8 shall not be deemed a Proceeding for the purposes of this Section if
the Person formed by such consolidation or into which the Company is merged or
the Person which acquires by sale such properties and assets as an entirety, as
the case may be, shall, as a part of such consolidation, merger, or sale comply
with the conditions set forth in Article Eight.

SECTION 1303.  PAYMENT BLOCKAGE UPON ACCELERATION OF SENIOR INDEBTEDNESS, ETC.

     During the continuance of any event of default with respect to any Senior
Indebtedness pursuant to which the maturity thereof may be accelerated, upon the
occurrence of (a) receipt by the Trustee of written notice from the holders of a
majority of the outstanding principal amount of the Senior Indebtedness or their
representative, or (b) if such event of default results from the acceleration of
the Securities, the date of such acceleration, no such payment may be made by
the Company upon or in respect of the Securities for a period ("Payment Blockage
Period") commencing on the earlier of the date of receipt of such notice or the
date of such acceleration and ending 179 days thereafter (unless such Payment
Blockage Period shall be terminated by written notice to the Trustee from the
holders of a majority of the outstanding principal amount of such Senior
Indebtedness or their representative who delivered such notice); provided,
however, that notwithstanding anything herein to the contrary, in no event will
a Payment Blockage Period extend beyond 179 days from the date on which such
Payment Blockage Period was commenced; provided further, that not more than one
Payment Blockage Period may be commenced with respect to the Securities during
any period of 360 consecutive days. For all purposes of this Section, no event
of default which existed or was continuing on the date of the commencement of
any Payment Blockage Period with respect to the Senior Indebtedness initiating
such Payment Blockage Period shall be, or be made, the basis for the
commencement of a second Payment Blockage Period by the holders of such Senior
Indebtedness or their representative whether or not within a period of 360
consecutive days unless such event of default shall have been cured or waived
for a period of not less than 90 consecutive days.

     In the event that, notwithstanding the foregoing, the Company shall make
any payment to the Trustee or any Holder of the Securities prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known, as set forth in Section 1310, to the
Trustee or, as the case may be, such Holder, then and in such event such payment
shall be paid over and delivered forthwith to the Company.

     The provisions of this Section shall not apply to any payment with respect
to which Section 1302 would be applicable.

SECTION 1304.  NO PAYMENT WHEN SENIOR INDEBTEDNESS IN DEFAULT.


                                      -79-




     In the event and during the continuation of any default in the payment of
principal of (or premium, if any) or interest on, or any other amounts owing
with respect to, any Senior Indebtedness when the same becomes due and payable
or in the event any judicial proceeding shall be pending with respect to any
such default, then, unless and until such default shall have been cured or
waived or shall have ceased to exist, no payment or distribution of any kind or
character, whether in cash, properties or Securities shall be made by the
Company on account of principal of (or premium, if any) or interest, if any, on
the Securities or on account of the purchase or other acquisition of Securities
by the Company or any Subsidiary.

     The Company shall give prompt written notice to the Trustee of any default
in payment of principal of or interest on any Senior Indebtedness; provided that
no failure to give such a notice shall have any effect whatsoever on the
subordination provisions described herein.

     In the event that, notwithstanding the foregoing, the Company shall make
any payment to the Trustee or the Holder of the Securities prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known as set forth in Section 1310, to the
Trustee or, as the case may be, such Holder, then and in such event such payment
shall be paid over and delivered forthwith to the Company.

     The provisions of this Section shall not apply to any payment with respect
to which Section 1302 would be applicable.

SECTION 1305.  PAYMENT PERMITTED IF NO DEFAULT.

     Nothing contained in this Article or elsewhere in this Indenture or in any
of the Securities shall prevent (a) the Company, at any time except during the
pendency of any Proceeding referred to in Section 1302 or under the conditions
described in Sections 1303 and 1304, from making payments at any time of
principal of (and premium, if any) or interest on the Securities, or (b) except
with respect to the payment over provisions of this Article, the application by
the Trustee of any money deposited with it hereunder to the payment of or on
account of the principal of (and premium, if any) or interest on the Securities
or the retention of such payment by the Holders, if, at the time of such
application by the Trustee, the Trustee did not have knowledge that such payment
would have been prohibited by the provisions of this Article.

SECTION 1306.  SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS.

     Subject to the payment in full of all Senior Indebtedness, or the provision
for such payment in cash or cash equivalents or otherwise in a manner
satisfactory to the holders of Senior Indebtedness, the Holders of the
Securities shall be subrogated to the extent of the 



                                      -80-





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

SECTION 1307.  PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

     The provisions of this Article are and are intended solely for the purpose
of defining the relative rights of the Holders of the Securities on the one hand
and the holders of Senior Indebtedness on the other hand. Nothing contained in
this Article or elsewhere in this Indenture or in the Securities is intended to
or shall (a) impair, as between the Company and the Holders of the Securities,
the obligations of the Company, which are absolute and unconditional, to pay to
the Holders of the Securities the principal of (and premium, if any) and
interest on the Securities as and when the same shall become due and payable in
accordance with their terms, or (b) affect the relative rights against the
Company of the Holders of the Securities and creditors of the Company other than
their rights in relation to the holders of Senior Indebtedness, or (c) prevent
the Trustee or the Holder of any Security from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture including, without
limitation, filing and voting claims in any Proceeding, subject to the rights,
if any, under this Article of the holders of Senior Indebtedness to receive
cash, property and securities otherwise payable or deliverable to the Trustee or
such Holder.

SECTION 1308.  TRUSTEE TO EFFECTUATE SUBORDINATION.

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

SECTION 1309.  NO WAIVER OF SUBORDINATION PROVISIONS.



                                      -81-





     No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof that any such holder may have or
be otherwise charged with.

SECTION 1310.  NOTICE TO TRUSTEE.

     The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities. Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a person representing itself as a holder of Senior Indebtedness or
from any trustee, agent or representative therefor.

SECTION 1311.  RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING AGENT.

     Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee, subject to the provisions of Article 6, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which a Proceeding is pending,
or a certificate of the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee for the benefit of creditors, agent or other Person making
such payment or distribution, delivered to the Trustee or to the Holders of
Securities, for the purpose of ascertaining the Persons entitled to participate
in such payment or distribution, the holders of 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.

SECTION 1312.  TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR INDEBTEDNESS.

     The Trustee, in its capacity as trustee under this Indenture, shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness and,
subject to the provisions of Section 6, shall not be liable to the holder of any
Senior Indebtedness if it shall pay over or deliver to Holders, the Company, or
any other Person, cash, property or securities to which any holder of Senior
Indebtedness shall be entitled to by virtue of this Article or otherwise.

SECTION 1313.  RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS; PRESERVATION
               OF TRUSTEE'S RIGHTS.




                                      -82-





     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article with respect to any Senior Indebtedness which may at
any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and, subject to the requirements of the Trust Indenture Act,
nothing in this Indenture shall deprive the Trustee of any of its rights as such
holder.

SECTION 1314.  ARTICLE APPLICABLE TO PAYING AGENTS.

     In case at any time any Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting hereunder, the term "Trustee" as
used in this Article shall in such case (unless the context otherwise requires)
be construed as extending to and including such Paying Agent within its meaning
as fully for all intent and purposes as if such Paying Agent were named in this
Article in addition to or in place of the Trustee.

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