The foregoing provisions of this Section 2.6(a) shall be in lieu of Section
316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of the
Trust Indenture Act is hereby expressly excluded from this Declaration and the

default shall cease to exist, and any Event of Default with respect to the
Preferred Securities arising therefrom shall be deemed to have been cured, for
every purpose of this Declaration, but no such waiver shall extend to any
subsequent or other default or an Event of Default with respect to the Preferred
Securities or impair any right consequent thereon.  Any waiver by the Holders of

    Default under the Declaration as provided below in this Section 2.6(b), the
    Event of Default under the Declaration shall also not be waivable; or

                                          9
<PAGE>

         (ii)      requires the consent or vote of a Super Majority to be
    waived, except where the Holders of the Common Securities are deemed to
    have waived such Event of Default under the Declaration as provided below
    in this Section 2.6(b), the Event of Default under the Declaration may only
    be waived by the vote of the Holders of at least the proportion in
    liquidation amount of the Common Securities that the relevant Super
    Majority represents of the aggregate principal amount of the Debentures
    outstanding;

PROVIDED FURTHER, each Holder of Common Securities will be deemed to have waived
any such Event of Default and all Events of Default with respect to the Common
Securities and its consequences until all Events of Default with respect to the
Preferred Securities have been cured, waived or otherwise eliminated, and until
such Events of Default have been so cured, waived or otherwise eliminated, the
Institutional Trustee will be deemed to be acting solely on behalf of the
Holders of the Preferred Securities and only the Holders of the Preferred
Securities will have the right to direct the Institutional Trustee in accordance
with the terms of the Securities.  The foregoing provisions of this Section
2.6(b) shall be in lieu of Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust
Indenture Act and such Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust
Indenture Act are hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act.  Subject to the foregoing
provisions of this Section 2.6(b), upon such waiver, any such default shall
cease to exist and any Event of Default with respect to the Common Securities
arising therefrom shall be deemed to have been cured for every purpose of this
Declaration, but no such waiver shall extend to any subsequent or other default
or Event of Default with respect to the Common Securities or impair any right
consequent thereon.

         (c)       A waiver of an Event of Default under the Indenture by the
Institutional Trustee at the direction of the Holders of the Preferred
Securities, constitutes a waiver of the corresponding Event of Default under
this Declaration.  The foregoing provisions of this Section 2.6(c) shall be in
lieu of Section 316(a)(1)(B) of the Trust Indenture Act and such Section
316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from this
Declaration and the Securities, as permitted by the Trust Indenture Act.

occurrence of an Event of Default, transmit by mail, first class postage
prepaid, to the Holders of the Securities, notices of all defaults with respect
to the Securities actually known to a Responsible Officer of the Institutional
Trustee, unless such defaults have been cured before the giving of such notice
(the term "defaults" for the purposes of this Section 2.7(a) being hereby
defined to be an Event of Default as defined in the Indenture, not including any
periods of grace provided for therein and irrespective of the giving of any
notice provided therein); PROVIDED THAT, except for a default in the payment of

payment of any sinking fund installment established for the Debentures, the
Institutional Trustee shall be protected in withholding such notice if and so
long as a Responsible Officer of the Institutional Trustee in good faith
determines that the withholding of such notice is in the interests of the
Holders of the Securities.

or authorized by this Declaration.  In particular, the Trust shall not and the
Trustees (including the Institutional Trustee) shall cause the Trust not to:

         (i)       invest any proceeds received by the Trust from holding the

    the Debentures where such consent shall be required unless the Trust shall
    have received an opinion of counsel to the effect that such modification
    will not cause more than an insubstantial risk that for United States
    federal income tax purposes the Trust will not be classified as a grantor
    trust.

SECTION 3.8        POWERS AND DUTIES OF THE INSTITUTIONAL TRUSTEE.

         (a)       The legal title to the Debentures shall be owned by and held
of record in the name of the Institutional Trustee in trust for the benefit of
the Holders of the Securities.  The right, title and interest of the
Institutional Trustee to the Debentures shall vest automatically in each Person
who may hereafter be appointed as Institutional Trustee in accordance with

                                          15
<PAGE>

Section 5.7.  Such vesting and cessation of title shall be effective whether or
not conveyancing documents with regard to the Debentures have been executed and
delivered.

         (b)       The Institutional Trustee shall not transfer its right,
title and interest in the Debentures to the Regular Trustees or to the Delaware
Trustee (if the Institutional Trustee does not also act as Delaware Trustee).

         (c)       The Institutional Trustee shall:

         (i)       establish and maintain a segregated non-interest bearing
    trust account (the "Institutional Trustee Account") in the name of and
    under the exclusive control of the Institutional Trustee on behalf of the
    Holders of the Securities and, upon the receipt of payments of funds made
    in respect of the Debentures held by the Institutional Trustee, deposit
    such funds into the Institutional Trustee Account and make payments to the
    Holders of the Preferred Securities and Holders of the Common Securities
    from the Institutional Trustee Account in accordance with Section 6.1.
    Funds in the Institutional Trustee Account shall be held uninvested until
    disbursed in accordance with this Declaration.  The Institutional Trustee
    Account shall be an account that is maintained with the Institutional
    Trustee or with a banking institution the rating on whose long-term
    unsecured indebtedness is at least equal to the rating assigned to the
    Preferred Securities by a "nationally recognized statistical rating
    organization", as that term is defined for purposes of Rule 436(g)(2) under
    the Securities Act;

         (ii)      engage in such ministerial activities as shall be necessary
    or appropriate to effect the redemption of the Preferred Securities and the

         (iii)          upon written notice of distribution issued by the
    Regular Trustees in accordance with the terms of the Securities, engage in
    such ministerial activities as shall be necessary or appropriate to effect
    the distribution of the Debentures to Holders of Securities upon the
    occurrence of certain special events (as may be defined in the terms of the
    Securities) arising from a change in law or a change in legal
    interpretation or other specified circumstances pursuant to the terms of
    the Securities.

         (d)       The Institutional Trustee shall take all actions and perform
such duties as may be specifically required of the Institutional Trustee
pursuant to the terms of the Securities.

         (e)       Subject to Sections 3.9 and 3.10, the Institutional Trustee
shall take any Legal Action which arises out of or in connection with an Event
of Default of which a Responsible Officer of the Institutional Trustee has
actual knowledge or the Institutional Trustee's duties and obligations under
this Declaration or the Trust Indenture Act; provided however, that if a
Declaration Event of Default has occurred and is continuing and such event is
attributable to the failure of the Debenture Issuer to pay interest or principal
on the

                                          16
<PAGE>

Debentures on the date such interest or principal is otherwise payable (or in
the case of redemption, on the redemption date), then a Holder of Preferred
Securities may directly institute a proceeding for enforcement of payment to
such Holder of the principal of or interest on the Debentures having a principal
amount equal to the aggregate liquidation amount of the Preferred Securities of
such Holder (a "Direct Action") on or after the respective due date specified in
the Debentures.  In connection with such Direct Action, the rights of the
Holders of the Common Securities Holder will be subrogated to the rights of such
Holder of Preferred Securities to the extent of any payment made by the Issuer
to such Holder of Preferred Securities in such Direct Action.  Except as
provided in the preceding sentences, the Holders of Preferred Securities will
not be able to exercise directly any other remedy available to the holders of
the Debentures.

         (f)       The Institutional Trustee shall not resign as a Trustee
unless either:

         (i)       the Trust has been completely liquidated and the proceeds of
    the liquidation distributed to the Holders of Securities pursuant to the
    terms of the Securities; or

         (ii)      a Successor Institutional Trustee has been appointed and has
    accepted that appointment in accordance with Section 5.7.

         (g)       The Institutional Trustee shall have the legal power to
exercise all of the rights, powers and privileges of a holder of Debentures
under the Indenture and, subject to Sections 3.9 and 3.10, if an Event of
Default actually known to a Responsible Officer of the Institutional Trustee
occurs and is continuing, the Institutional Trustee shall, for the benefit of
Holders of the Securities, enforce its rights as holder of the Debentures
subject to the rights of the Holders pursuant to the terms of such Securities.

         (h)       The Institutional Trustee may authorize one or more Persons
(each, a "Paying Agent") to pay Distributions, redemption payments or
liquidation payments on behalf of the Trust with respect to all securities and
any such Paying Agent shall comply with Section 317(b) of the Trust Indenture
Act.  Any Paying Agent may be removed by the Institutional Trustee at any time
and a successor Paying Agent or additional Paying Agents may be appointed at any
time by the Institutional Trustee.

         (i)       Subject to this Section 3.8, the Institutional Trustee shall
have none of the duties, liabilities, powers or the authority of the Regular
Trustees set forth in Section 3.6.

         The Institutional Trustee must exercise the powers set forth in this
Section 3.8 in a manner that is consistent with the purposes and functions of
the Trust set out in Section 3.3, and the Institutional Trustee shall not take
any action that is inconsistent with the purposes and functions of the Trust set
out in Section 3.3.

Event of Default and after the curing of all Events of Default that may have
occurred, shall undertake to perform only such duties as are specifically set
forth in this Declaration and no implied covenants shall be read into this
Declaration against the Institutional Trustee.  In case an Event of Default has
occurred (that has not been cured or waived pursuant to Section 2.6) of which a
Responsible Officer of the Institutional Trustee has actual knowledge, the
Institutional Trustee shall exercise such of the rights and powers vested in it
by this Declaration, and use the same degree of care and skill in their
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of his or her own affairs.

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

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

              (A)       the duties and obligations of the Institutional Trustee
         shall be determined solely by the express provisions of this

         set forth in this Declaration, and no implied covenants or obligations
         shall be read into this Declaration against the Institutional Trustee;
         and

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

         (ii)      the Institutional Trustee shall not be liable for any error
    of judgment made in good faith by a Responsible Officer of the
    Institutional Trustee, unless it shall be proved that the Institutional

         (iii)     the Institutional Trustee shall not be liable with respect
    to any action taken or omitted to be taken by it in good faith in
    accordance with the direction of the Holders of not less than a Majority in
    liquidation amount of the Securities relating to the time, method and place
    of conducting any proceeding for any remedy available to the

                                          18
<PAGE>

    Institutional Trustee, or exercising any trust or power conferred upon the
    Institutional Trustee under this Declaration;

         (iv)      no provision of this Declaration shall require the
    Institutional Trustee to expend or risk its own funds or otherwise incur
    personal financial liability in the performance of any of its duties or in
    the exercise of any of its rights or powers, if it shall have reasonable
    grounds for believing that the repayment of such funds or liability is not
    reasonably assured to it under the terms of this Declaration or indemnity
    reasonably satisfactory to the Institutional Trustee against such risk or
    liability is not reasonably assured to it;

         (v)       the Institutional Trustee's sole duty with respect to the
    custody, safe keeping and physical preservation of the Debentures and the
    Institutional Trustee Account shall be to deal with such property in a
    similar manner as the Institutional Trustee deals with similar property for
    its own account, subject to the protections and limitations on liability
    afforded to the Institutional Trustee under this Declaration and the Trust
    Indenture Act;

         (vi)      the Institutional Trustee shall have no duty or liability
    for or with respect to the value, genuineness, existence or sufficiency of
    the Debentures or the payment of any taxes or assessments levied thereon or
    in connection therewith;

         (vii)     the Institutional Trustee shall not be liable for any
    interest on any money received by it except as it may otherwise agree with
    the Sponsor.  Money held by the Institutional Trustee need not be
    segregated from other funds held by it except in relation to the
    Institutional Trustee Account maintained by the Institutional Trustee
    pursuant to Section 3.8(c)(i) and except to the extent otherwise required
    by law; and

         (viii)    the Institutional Trustee shall not be responsible for
    monitoring the compliance by the Regular Trustees or the Sponsor with their
    respective duties under this Declaration, nor shall the Institutional
    Trustee be liable for any default or misconduct of the Regular Trustees or
    the Sponsor.

    Event of Default, of its obligation to exercise the rights and powers
    vested in it by this Declaration;

         (vii)     the Institutional Trustee shall not be bound to make any

         substantially the same terms as the Preferred Securities (the

<PAGE>

         the Successor Securities rank the same as the Preferred Securities

         redemption and otherwise;

         (ii)      the Debenture Issuer expressly acknowledges a trustee of the

    issuance, on any national securities exchange or with another organization
    on which the Preferred Securities are then listed or quoted;

         (iv)      such merger, consolidation, amalgamation or replacement does
    not cause the Preferred Securities (including any Successor Securities) to
    be downgraded by any nationally recognized statistical rating organization;

         (v)       such merger, consolidation, amalgamation or replacement does
    not adversely affect the rights, preferences and privileges of the Holders
    of the  Securities (including any Successor Securities) in any material
    respect (other than with respect to any dilution of such Holders' interests
    in the Preferred Securities as a result of such merger, consolidation,
    amalgamation or replacement);

         (vi)      such Successor Entity has a purpose identical to that of the
    Trust;

         (vii)     prior to such merger, consolidation, amalgamation or
    replacement, the Sponsor has received an opinion of a nationally recognized
    independent counsel to the Trust experienced in such matters to the effect
    that:

                   (A)  such merger, consolidation, amalgamation or replacement
         does not adversely affect the rights, preferences and privileges of
         the Holders of the Securities (including any Successor Securities) in
         any material respect (other than with respect to any dilution of the
         Holders' interest in the new entity);

                   (B)  following such merger, consolidation, amalgamation or
         replacement, neither the Trust nor the Successor Entity will be
         required to register as an Investment Company; and

                   (C)  following such merger, consolidation, amalgamation or
         replacement, the Trust (or the Successor Entity) will continue to be
         classified as a grantor trust for United States federal income tax
         purposes; and

         (viii)    the Sponsor guarantees the obligations of such Successor
    Entity under the Successor Securities at least to the extent provided by
    the Preferred Securities Guarantee.

with the consent of Holders of 100% in liquidation amount of the Securities,
consolidate, amalgamate, merge with or into, or be replaced by any other entity
or permit any other entity to consolidate, amalgamate, merge with or into, or
replace it if such consolidation, amalgamation, merger or replacement would
cause the Trust or Successor Entity to be classified as other than a grantor
trust for United States federal income tax purposes.

on the ground that the meeting has not been lawfully called or convened.  Unless
provided otherwise in this Declaration, any action of the Regular Trustees may
be taken at a meeting by vote of a majority of the Regular Trustees present
(whether in person or by telephone) and eligible to vote with respect to such
matter, provided that a Quorum is present, or without a meeting by the unanimous

expedient, to the extent such delegation is not prohibited by applicable law or

substantially all the corporate trust business of the Institutional Trustee or
the Delaware Trustee, as the case may be, shall be the successor of the

                                ISSUANCE OF SECURITIES

SECTION 7.1        GENERAL PROVISIONS REGARDING SECURITIES.

         (a)       The Regular Trustees shall on behalf of the Trust issue one
class of preferred securities representing undivided beneficial interests in the
assets of the Trust having such terms as are set forth in Annex I (the
"Preferred Securities") and one class of convertible common securities,
representing undivided beneficial interests in the assets of the Trust having
such terms as are set forth in Annex I (the "Common Securities").  The Trust
shall issue no securities or other interests in the assets of the Trust other
than the Preferred Securities and the Common Securities.

         (b)       The Certificates shall be signed on behalf of the Trust by a
Regular Trustee.  Such signature shall be the manual signature of any present or
any future Regular Trustee.  In case any Regular Trustee of the Trust who shall
have signed any of the Securities shall cease to be such Regular Trustee before
the Certificates so signed shall be delivered by the Trust, such Certificates
nevertheless may be delivered as though the person who signed such Certificates
had not ceased to be such Regular Trustee; and any Certificate may be signed on
behalf of the Trust by such persons who, at the actual date of execution of such
Security, shall be the Regular Trustees of the Trust, although at the date of
the execution and delivery of the Declaration any such person was not such a
Regular Trustee.  Certificates shall be printed, lithographed or engraved or may
be produced in any other manner as is reasonably acceptable to the Regular
Trustees, as evidenced by their execution thereof, and may have such letters,
numbers or other marks of identification or designation and such legends or
endorsements as the Regular Trustees may deem appropriate, or as may be required
to comply with any law or with any rule or regulation of any stock exchange on
which Securities may be listed, or to conform to usage.

         (c)       The consideration received by the Trust for the issuance of
the Securities shall constitute a contribution to the capital of the Trust and
shall not constitute a loan to the Trust. 

         (d)       Upon issuance of the Securities as provided in this
Declaration, the Securities so issued shall be deemed to be validly issued,
fully paid and non-assessable.

         (e)       Every Person, by virtue of having become a Holder or a
Preferred Security Beneficial Owner in accordance with the terms of this
Declaration, shall be deemed to have expressly assented and agreed to the terms
of, and shall be bound by, this Declaration.

form, the Trust shall maintain in the Borough of Manhattan, City of New York,
State of New York, an office or agency where the Preferred Securities may be
presented for payment ("Paying Agent).  The term "Paying Agent" includes any
additional paying agent.  The Trust may change any Paying Agent without prior
notice to any Holder.  The Trust shall notify the Institutional Trustee of the
name and address of any Agent not a party to this Declaration.  If the Trust
fails to appoint or maintain another entity as Paying Agent, the Institutional
Trustee shall act as such.  The Trust or any of its Affiliates may act as Paying
Agent.  The Trust shall act as Paying Agent for the Common Securities.

SECTION 8.1        TERMINATION OF TRUST.

         (a)       The Trust shall terminate:

         (i)       upon the bankruptcy of the Sponsor;

         (ii)      upon the filing of a certificate of dissolution or its
    equivalent with respect to the Sponsor; the filing of a certificate of
    cancellation with respect to the Trust after having obtained the consent of
    a majority in liquidation amount of the Securities, voting together as a
    single class, to file such certificate of cancellation or the revocation of
    the Sponsor's charter and the expiration of 90 days after the date of
    revocation without a reinstatement thereof;

         (iii)     upon the entry of a decree of judicial dissolution of the
    Holder of the Common Securities, the Sponsor or the Trust; 

         (iv)      when all of the Securities shall have been called for
    redemption and the amounts necessary for redemption thereof shall have been
    paid to the Holders in accordance with the terms of the Securities;
 
         (v)       upon the occurrence and continuation of a Tax Event pursuant
    to which the Trust shall have been dissolved in accordance with the terms
    of the Securities and all of the Debentures endorsed thereon shall have
    been distributed to the Holders of Securities in exchange for all of the
    Securities; or
 
         (vi)      before the issuance of any Securities, with the consent of
    all of the Regular Trustees and the Sponsor.

                                          32

<PAGE>

         (b)       As soon as is practicable after the occurrence of an event
referred to in Section 8.1(a), the Trustees shall file a certificate of
cancellation with the Secretary of State of the State of Delaware.

         (c)       The provisions of Section 10.4 shall survive the termination
of the Trust.


                                      ARTICLE IX
                                TRANSFER OF INTERESTS

SECTION 9.1        TRANSFER OF SECURITIES.

         (a)       Securities may be transferred, in whole or in part, only in
accordance with the terms and conditions set forth in this Declaration and in
the terms of the Securities.  Any transfer or purported transfer of any Security
not made in accordance with this Declaration shall be null and void.

         (b)       Subject to this Article IX, Preferred Securities shall be
freely transferable.  

         (c)       Subject to this Article IX, the Sponsor and any Related
Party may only transfer Common Securities to the Sponsor or a Related Party of
the Sponsor; PROVIDED THAT, any such transfer is subject to the condition
precedent that the transferor obtain the written opinion of nationally
recognized independent counsel experienced in such matters that such transfer
would not cause more than an insubstantial risk that:

         (i)       the Trust would not be classified for United States federal
    income tax purposes as a grantor trust; and

         (ii)      the Trust would be an Investment Company or the transferee
    would become an Investment Company.

SECTION 9.2        TRANSFER OF CERTIFICATES.

         The Regular Trustees shall provide for the registration of
Certificates and of transfers of Certificates, which will be effected without
charge but only upon payment (with such indemnity as the Regular Trustees may
require) in respect of any tax or other government charges that may be imposed
in relation to it.  Upon surrender for registration of transfer of any
Certificate, the Regular Trustees shall cause one or more new Certificates to be
issued in the name of the designated transferee or transferees.  Every
Certificate surrendered for registration of transfer shall be accompanied by a
written instrument of transfer in form satisfactory to the Regular Trustees duly
executed by the Holder or such Holder's attorney duly authorized in writing. 
Each Certificate surrendered for registration of transfer shall be canceled by
the Regular Trustees.  A transferee of a Certificate shall be entitled to the
rights and subject to the 

                                          33

<PAGE>


obligations of a Holder hereunder upon the receipt by such transferee of a
Certificate.  By acceptance of a Certificate, each transferee shall be deemed to
have agreed to be bound by this Declaration.

SECTION 9.3        DEEMED SECURITY HOLDERS.

         The Trustees may treat the Person in whose name any Certificate shall
be registered on the books and records of the Trust as the sole holder of such
Certificate and of the Securities represented by such Certificate for purposes
of receiving Distributions and for all other purposes whatsoever and,
accordingly, shall not be bound to recognize any equitable or other claim to or
interest in such Certificate or in the Securities represented by such
Certificate on the part of any Person, whether or not the Trust shall have
actual or other notice thereof.

SECTION 9.4        BOOK ENTRY INTERESTS.

         Unless otherwise specified in the terms of the Preferred Securities,
the Preferred Securities Certificates, on original issuance, will be issued in
the form of one or more, fully registered, global Preferred Security
Certificates (each a "Global Certificate"), to be delivered to DTC, the initial
Clearing Agency, by, or on behalf of, the Trust.  Such Global Certificates shall
initially be registered on the books and records of the Trust in the name of
Cede & Co., the nominee of DTC, and no Preferred Security Beneficial Owner will
receive a definitive Preferred Security Certificate representing such Preferred
Security Beneficial Owner's interests in such Global Certificates, except as
provided in Section 9.7.  Unless and until definitive, fully registered
Preferred Security Certificates (the "Definitive Preferred Security
Certificates") have been issued to the Preferred Security Beneficial Owners
pursuant to Section 9.7:

         (a)       the provisions of this Section 9.4 shall be in full force
    and effect;

         (b)       the Trust and the Trustees shall be entitled to deal with
    the Clearing Agency for all purposes of this Declaration (including the
    payment of Distributions on the Global Certificates and receiving
    approvals, votes or consents hereunder) as the Holder of the Preferred
    Securities and the sole holder of the Global Certificates and shall have no
    obligation to the Preferred Security Beneficial Owners;

         (c)       to the extent that the provisions of this Section 9.4
    conflict with any other provisions of this Declaration, the provisions of
    this Section 9.4 shall control; and

         (d)       the rights of the Preferred Security Beneficial Owners shall
    be exercised only through the Clearing Agency and shall be limited to those
    established by law and agreements between such Preferred Security
    Beneficial Owners and the Clearing Agency and/or the Clearing Agency
    Participants and receive and transmit payments of Distributions on the
    Global Certificates to such Clearing Agency Participants.  DTC will make
    book entry transfers among the Clearing Agency Participants.

SECTION 9.5        NOTICES TO CLEARING AGENCY.

         Whenever a notice or other communication to the Preferred Security
Holders is required under this Declaration, unless and until Definitive
Preferred Security Certificates shall have been issued to the Preferred Security
Beneficial Owners pursuant to Section 9.7, the Regular Trustees shall give all
such notices and communications specified herein to be given to the Preferred
Security Holders to the Clearing Agency, and shall have no notice obligations to
the Preferred Security Beneficial Owners.

SECTION 9.6        APPOINTMENT OF SUCCESSOR CLEARING AGENCY.

         If any Clearing Agency elects to discontinue its services as
securities depositary with respect to the Preferred Securities, the Regular
Trustees may, in their sole discretion, appoint a successor Clearing Agency with
respect to such Preferred Securities.

SECTION 9.7        DEFINITIVE PREFERRED SECURITY CERTIFICATES. 

         If:

         (a)       a Clearing Agency elects to discontinue its services as
    securities depositary with respect to the Preferred Securities and a
    successor Clearing Agency is not appointed within 90 days after such
    discontinuance pursuant to Section 9.6; or 

         (b)       the Regular Trustees elect after consultation with the
    Sponsor to terminate the book entry system through the Clearing Agency with
    respect to the Preferred Securities, 

         then:

              (x)       Definitive Preferred Security Certificates shall be
         prepared by the Regular Trustees on behalf of the Trust with respect
         to such Preferred Securities; and

              (y)       upon surrender of the Global Certificates by the
         Clearing Agency, accompanied by registration instructions, the Regular
         Trustees shall cause Definitive Certificates to be delivered to
         Preferred Security Beneficial Owners in accordance with the
         instructions of the Clearing Agency.  Neither the Trustees nor the
         Trust shall be liable for any delay in delivery of such instructions
         and each of them may conclusively rely on and shall be protected in
         relying on, said instructions of the Clearing Agency.  The Definitive
         Preferred Security Certificates shall be printed, lithographed or
         engraved or may be produced in any other manner as is reasonably
         acceptable to the Regular Trustees, as evidenced by their execution
         thereof, and may have such letters, numbers or other marks of
         identification or designation and such legends or endorsements as the
         Regular

                                          35

<PAGE>


         Trustees may deem appropriate, or as may be required to comply with
         any law or with any rule or regulation made pursuant thereto or with
         any rule or regulation of any stock exchange on which Preferred
         Securities may be listed, or to conform to usage.

SECTION 9.8        MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

         If: 

         (a)       any mutilated Certificates should be surrendered to the
    Regular Trustees, or if the Regular Trustees shall receive evidence to
    their satisfaction of the destruction, loss or theft of any Certificate;
    and 

         (b)       there shall be delivered to the Regular Trustees such
    security or indemnity as may be required by them to keep each of them
    harmless.

then, in the absence of notice that such Certificate shall have been acquired by
a bona fide purchaser, any Regular Trustee on behalf of the Trust shall execute
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Certificate, a new Certificate of like denomination.  In connection
with the issuance of any new Certificate under this Section 9.8, the Regular
Trustees may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection therewith.  Any duplicate
Certificate issued pursuant to this Section shall constitute conclusive evidence
of an ownership interest in the relevant Securities, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time.

                              LIMITATION OF LIABILITY OF
                      HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

SECTION 10.1       LIABILITY.

         (a)       Except as expressly set forth in this Declaration, the
Securities Guarantees and the terms of the Securities, the Sponsor shall not be:

         (i)       personally liable for the return of any portion of the
    capital contributions (or any return thereon) of the Holders of the
    Securities which shall be made solely from assets of the Trust; and

         (ii)      be required to pay to the Trust or to any Holder of
    Securities any deficit upon dissolution of the Trust or otherwise.

                                          36

<PAGE>

         (b)       The Holder of the Common Securities shall be liable for all
of the debts and obligations of the Trust (other than with respect to the
Securities) to the extent not satisfied out of the Trust's assets.

         (c)       Pursuant to Section 3803(a) of the Business Trust Act, the
Holders of the Preferred Securities shall be entitled to the same limitation of
personal liability extended to stockholders of private corporations for profit
organized under the General Corporation Law of the State of Delaware.

SECTION 10.2       EXCULPATION.

         (a)       No Indemnified Person shall be liable, responsible or
accountable in damages or otherwise to the Trust or any Covered Person for any
loss, damage or claim incurred by reason of any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of the
authority conferred on such Indemnified Person by this Declaration or by law,
except that an Indemnified Person shall be liable for any such loss, damage or
claim incurred by reason of such Indemnified Person's gross negligence or
willful misconduct with respect to such acts or omissions.

         (b)       An Indemnified Person shall be fully protected in relying in
good faith upon the records of the Trust and upon such information, opinions,
reports or statements presented to the Trust by any Person as to matters the
Indemnified Person reasonably believes are within such other Person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Trust, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses, or any other facts pertinent to the existence and amount of assets from
which Distributions to Holders of Securities might properly be paid.

SECTION 10.3       FIDUCIARY DUTY.

         (a)       To the extent that, at law or in equity, an Indemnified
Person has duties (including fiduciary duties) and liabilities relating thereto
to the Trust or to any other Covered Person, an Indemnified Person acting under
this Declaration shall not be liable to the Trust or to any other Covered Person
for its good faith reliance on the provisions of this Declaration.  The
provisions of this Declaration, to the extent that they restrict the duties and
liabilities of an Indemnified Person otherwise existing at law or in equity
(other than the duties imposed on the Institutional Trustee under the Trust
Indenture Act), are agreed by the parties hereto to replace such other duties
and liabilities of such Indemnified Person.

         (b)       Unless otherwise expressly provided herein: 

         (i)       whenever a conflict of interest exists or arises between any
    Covered Persons; or

                                          37

<PAGE>

         (ii)      whenever this Declaration or any other agreement
    contemplated herein or therein provides that an Indemnified Person shall
    act in a manner that is, or provides terms that are, fair and reasonable to
    the Trust or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices, and any applicable generally accepted accounting
practices or principles.  In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Declaration or any other agreement
contemplated herein or of any duty or obligation of the Indemnified Person at
law or in equity or otherwise.

         (c)       Whenever in this Declaration an Indemnified Person is
permitted or required to make a decision: 

         (i)       in its "discretion" or under a grant of similar authority,
    the Indemnified Person shall be entitled to consider such interests and
    factors as it desires, including its own interests, and shall have no duty
    or obligation to give any consideration to any interest of or factors
    affecting the Trust or any other Person; or

         (ii)      in its "good faith" or under another express standard, the
    Indemnified Person shall act under such express standard and shall not be
    subject to any other or different standard imposed by this Declaration or
    by applicable law.

SECTION 10.4       INDEMNIFICATION.

                   (a)(i)    The Debenture Issuer shall indemnify, to the full
    extent permitted by law, any Company Indemnified Person who was or is a
    party or is threatened to be made a party to any threatened, pending or
    completed action, suit or proceeding, whether civil, criminal,
    administrative or investigative (other than an action by or in the right of
    the Trust) by reason of the fact that he is or was a Company Indemnified
    Person against expenses (including attorneys' fees), judgments, fines and
    amounts paid in settlement actually and reasonably incurred by him in
    connection with such action, suit or proceeding if he acted in good faith
    and in a manner he reasonably believed to be in or not opposed to the best
    interests of the Trust, and, with respect to any criminal action or
    proceeding, had no reasonable cause to believe his conduct was unlawful. 
    The termination of any action, suit or proceeding by judgment, order,
    settlement, conviction, or upon a plea of NOLO CONTENDERE or its
    equivalent, shall not, of itself, create a presumption that the Company
    Indemnified Person did not act in good faith and in a manner which he
    reasonably believed to be in or not opposed to the best interests of the
    Trust, and, with respect to any criminal action or proceeding, had
    reasonable cause to believe that his conduct was unlawful.

                                          38

<PAGE>

         (ii)      The Debenture Issuer shall indemnify, to the full extent
    permitted by law, any Company Indemnified Person who was or is a party or
    is threatened to be made a party to any threatened, pending or completed
    action or suit by or in the right of the Trust to procure a judgment in its
    favor by reason of the fact that he is or was a Company Indemnified Person
    against expenses (including attorneys' fees) actually and reasonably
    incurred by him in connection with the defense or settlement of such action
    or suit if he acted in good faith and in a manner he reasonably believed to
    be in or not opposed to the best interests of the Trust and except that no
    such indemnification shall be made in respect of any claim, issue or matter
    as to which such Company Indemnified Person shall have been adjudged to be
    liable to the Trust unless and only to the extent that the Court of
    Chancery of Delaware or the court in which such action or suit was brought
    shall determine upon application that, despite the adjudication of
    liability but in view of all the circumstances of the case, such person is
    fairly and reasonably entitled to indemnity for such expenses which such
    Court of Chancery or such other court shall deem proper.

         (iii)     To the extent that a Company Indemnified Person shall be
    successful on the merits or otherwise (including dismissal of an action
    without prejudice or the settlement of an action without admission of
    liability) in defense of any action, suit or proceeding referred to in
    paragraphs (i) and (ii) of this Section 10.4(a), or in defense of any
    claim, issue or matter therein, he shall be indemnified, to the full extent
    permitted by law, against expenses (including attorneys' fees) actually and
    reasonably incurred by him in connection therewith.

         (iv)      Any indemnification under paragraphs (i) and (ii) of this
    Section 10.4(a) (unless ordered by a court) shall be made by the Debenture
    Issuer only as authorized in the specific case upon a determination that
    indemnification of the Company Indemnified Person is proper in the
    circumstances because he has met the applicable standard of conduct set
    forth in paragraphs (i) and (ii).  Such determination shall be made (1) by
    the Regular Trustees by a majority vote of a quorum consisting of such
    Regular Trustees who were not parties to such action, suit or proceeding,
    (2) if such a quorum is not obtainable, or, even if obtainable, if a quorum
    of disinterested Regular Trustees so directs, by independent legal counsel
    in a written opinion, or (3) by the Common Security Holder of the Trust.

         (v)       Expenses (including attorneys' fees) incurred by a Company
    Indemnified Person in defending a civil, criminal, administrative or
    investigative action, suit or proceeding referred to in paragraphs (i) and
    (ii) of this Section 10.4(a) shall be paid by the Debenture Issuer in
    advance of the final disposition of such action, suit or proceeding upon
    receipt of an undertaking by or on behalf of such Company Indemnified
    Person to repay such amount if it shall ultimately be determined that he is
    not entitled to be indemnified by the Debenture Issuer as authorized in
    this Section 10.4(a).  Notwithstanding the foregoing, no advance shall be
    made by the Debenture Issuer if a determination is reasonably and promptly
    made (i) by the Regular Trustees by a majority vote of a 

                                          39

<PAGE>


    quorum of disinterested Regular Trustees, (ii) if such a quorum is not
    obtainable, or, even if obtainable, if a quorum of disinterested Regular
    Trustees so directs, by independent legal counsel in a written opinion or
    (iii) the Common Security Holder of the Trust, that, based upon the facts
    known to the Regular Trustees, counsel or the Common Security Holder at the
    time such determination is made, such Company Indemnified Person acted in
    bad faith or in a manner that such person did not believe to be in or not
    opposed to the best interests of the Trust, or, with respect to any
    criminal proceeding, that such Company Indemnified Person believed or had
    reasonable cause to believe his conduct was unlawful.  In no event shall
    any advance be made in instances where the Regular Trustees, independent
    legal counsel or Common Security Holder reasonably determine that such
    person deliberately breached his duty to the Trust or its Common or
    Preferred Security Holders.

         (vi)      The indemnification and advancement of expenses provided by,
    or granted pursuant to, the other paragraphs of this Section 10.4(a) shall
    not be deemed exclusive of any other rights to which those seeking
    indemnification and advancement of expenses may be entitled under any
    agreement, vote of stockholders or disinterested directors of the Debenture
    Issuer or Preferred Security Holders of the Trust or otherwise, both as to
    action in his official capacity and as to action in another capacity while
    holding such office.  All rights to indemnification under this Section
    10.4(a) shall be deemed to be provided by a contract between the Debenture
    Issuer and each Company Indemnified Person who serves in such capacity at
    any time while this Section 10.4(a) is in effect.  Any repeal or
    modification of this Section 10.4(a) shall not affect any rights or
    obligations then existing.

         (vii)     The Debenture Issuer or the Trust may purchase and maintain
    insurance on behalf of any person who is or was a Company Indemnified
    Person against any liability asserted against him and incurred by him in
    any such capacity, or arising out of his status as such, whether or not the
    Debenture Issuer would have the power to indemnify him against such
    liability under the provisions of this Section 10.4(a).

         (viii)    For purposes of this Section 10.4(a), references to "the
    Trust" shall include, in addition to the resulting or surviving entity, any
    constituent entity (including any constituent of a constituent) absorbed in
    a consolidation or merger, so that any person who is or was a director,
    trustee, officer or employee of such constituent entity, or is or was
    serving at the request of such constituent entity as a director, trustee,
    officer, employee or agent of another entity, shall stand in the same
    position under the provisions of this Section 10.4(a) with respect to the
    resulting or surviving entity as he would have with respect to such
    constituent entity if its separate existence had continued.

         (ix)      The indemnification and advancement of expenses provided by,
    or granted pursuant to, this Section 10.4(a) shall, unless otherwise
    provided when authorized or ratified, continue as to a person who has
    ceased to be a Company Indemnified Person and shall inure to the benefit of
    the heirs, executors and administrators of such a person.

                                          40

<PAGE>

         (b)       The Sponsor agrees to indemnify the (i) Institutional
Trustee, (ii) the Delaware Trustee, (iii) any Affiliate of the Institutional
Trustee and the Delaware Trustee, and (iv) any officers, directors,
shareholders, members, partners, employees, representatives, custodians,
nominees or agents of the Institutional Trustee and the Delaware Trustee (each
of the Persons in (i) through (iv) being referred to as a "Fiduciary Indemnified
Person") for, and to hold each Fiduciary Indemnified Person harmless against,
any loss, liability, taxes  or expense incurred without gross negligence or bad
faith on its part, arising out of or in connection with the acceptance or
administration or the trust or trusts hereunder, including the costs and
expenses (including reasonable legal fees and expenses) of defending itself
against or investigating any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder.  The obligation to
indemnify as set forth in this Section 10.4(b) shall survive the satisfaction
and discharge of this Declaration.

SECTION 10.5       OUTSIDE BUSINESSES.

         Any Covered Person, the Sponsor, the Delaware Trustee and the
Institutional Trustee may engage in or possess an interest in other business
ventures of any nature or description, independently or with others, similar or
dissimilar to the business of the Trust, and the Trust and the Holders of
Securities shall have no rights by virtue of this Declaration in and to such
independent ventures or the income or profits derived therefrom, and the pursuit
of any such venture, even if competitive with the business of the Trust, shall
not be deemed wrongful or improper.  No Covered Person, the Sponsor, the
Delaware Trustee, or the Institutional Trustee shall be obligated to present any
particular investment or other opportunity to the Trust even if such opportunity
is of a character that, if presented to the Trust, could be taken by the Trust,
and any Covered Person, the Sponsor, the Delaware Trustee and the Institutional
Trustee shall have the right to take for its own account (individually or as a

         (a)       At all times during the existence of the Trust, the Regular
Trustees shall keep, or cause to be kept, full books of account, records and
supporting documents, which shall reflect in reasonable detail, each transaction
of the Trust.  The books of account shall be maintained on the accrual method of
accounting, in accordance with generally accepted accounting principles,

of the Trust shall be examined by and reported upon as of the end of each Fiscal
Year of the Trust by a firm of independent certified public accountants selected

         (b)       The Regular Trustees shall cause to be prepared and
delivered to each of the Holders of Securities, within 90 days after the end of
each Fiscal Year of the Trust, annual financial statements of the Trust,
including a balance sheet of the Trust as of the end of such Fiscal Year, and
the related statements of income or loss.

         (c)       The Regular Trustees shall cause to be duly prepared and
delivered to each of the Holders of Securities, any annual United States federal
income tax information statement, required by the Code, containing such
information with regard to the Securities held by each Holder as is required by
the Code and the Treasury Regulations.  Notwithstanding any right under the Code
to deliver any such statement at a later date, the Regular Trustees shall
endeavor to deliver all such statements within 30 days after the end of each
Fiscal Year of the Trust.

         (d)       The Regular Trustees shall cause to be duly prepared and

directly to the Institutional Trustee Account and no other funds of the Trust

SECTION 11.4       WITHHOLDING.

         The Trust and the Regular Trustees shall comply with all withholding
requirements under United States federal, state and local law.  The Trust shall
request, and the Holders shall provide to the Trust, such forms or certificates
as are necessary to establish an exemption from withholding with respect to each
Holder, and any representations and forms as shall reasonably be requested by
the Trust to assist it in determining the extent of, and in fulfilling, its
withholding obligations.  The Regular Trustees shall file required forms with
applicable jurisdictions and, unless an exemption from withholding is properly
established by a Holder, shall remit amounts withheld with respect to the Holder
to applicable jurisdictions.  To the extent that the Trust is required to
withhold and pay over any amounts to any authority with respect to distributions
or allocations to any Holder, the amount withheld shall be deemed to be a
distribution in the amount of the withholding to the Holder.  In the event of
any claimed over withholding, Holders shall be limited to an action against the
applicable jurisdiction.  If the amount required to be withheld was not withheld
from actual Distributions made, the Trust may reduce subsequent Distributions by
the amount of such withholding.

SECTION 12.2       MEETINGS OF THE HOLDERS OF SECURITIES; ACTION BY WRITTEN

         (a)       Meetings of the Holders of any class of Securities may be 
called at any time by the Regular Trustees (or as provided in the terms of 
the Securities) to consider and act on any matter on which Holders of such 
class of Securities are entitled to act under the terms of this Declaration, 
the terms of the Securities or the rules of any stock exchange on which the 
Preferred Securities are listed or admitted for trading.  The Regular 
Trustees shall call a meeting of the Holders of such class if directed to do 
so by the Holders of at least 10% in liquidation amount of such class of 
Securities.  Such direction shall be given by delivering to the Regular 
Trustees one or more calls in a writing stating that the signing Holders of 
Securities wish to call a meeting and indicating the general or specific 
purpose for which the meeting is to be called.  Any Holders of Securities 
calling a meeting shall specify in writing the Security Certificates held by 
the Holders of Securities exercising the right to call a meeting and only 
those Securities specified shall be counted for purposes of determining 
whether the required percentage set forth in the second sentence of this 
paragraph has been met.

         (b)       Except to the extent otherwise provided in the terms of 
the Securities, the following provisions shall apply to meetings of Holders 
of Securities:

         (i)       notice of any such meeting shall be given to all the 
     Holders of Securities having a right to vote thereat at least 7 days and 
     not more than 60 days before the date of such meeting.  Whenever a vote, 
     consent or approval of the Holders of Securities is permitted or 
     required under this Declaration or the rules of any stock exchange on 
     which the Preferred Securities are listed or admitted for trading, such 
     vote, consent or approval may be given at a meeting of the Holders of 
     Securities.  Any action that may be taken at a meeting of the Holders of 
     Securities may be taken without a meeting if a consent in writing 
     setting forth the action so taken is signed by the Holders of Securities 
     owning not less than the minimum amount of Securities in liquidation 
     amount that would be necessary to authorize or take such action at a 
     meeting at which all Holders of Securities having a right to vote 
     thereon were present and voting.  Prompt notice of the taking of action 
     without a meeting shall be given to the Holders of Securities entitled 
     to vote who 


                                          45

<PAGE>

    have not consented in writing.  The Regular Trustees may specify that any
    written ballot submitted to the Security Holder for the purpose of taking
    any action without a meeting shall be returned to the Trust within the time
    specified by the Regular Trustees;

         (ii)      each Holder of a Security may authorize any Person to act
    for it by proxy on all matters in which a Holder of Securities is entitled
    to participate, including waiving notice of any meeting, or voting or
    participating at a meeting.  No proxy shall be valid after the expiration
    of 11 months from the date thereof unless otherwise provided in the proxy. 
    Every proxy shall be revocable at the pleasure of the Holder of Securities
    executing it.  Except as otherwise provided herein, all matters relating to
    the giving, voting or validity of proxies shall be governed by the General
    Corporation Law of the State of Delaware relating to proxies, and judicial
    interpretations thereunder, as if the Trust were a Delaware corporation and
    the Holders of the Securities were stockholders of a Delaware corporation;

         (iii)     each meeting of the Holders of the Securities shall be
    conducted by the Regular Trustees or by such other Person that the Regular
    Trustees may designate; and

         (iv)      unless the Business Trust Act, this Declaration, the terms
    of the Securities, the Trust Indenture Act or the listing rules of any
    stock exchange on which the Preferred Securities are then listed or
    trading, otherwise provides, the Regular Trustees, in their sole
    discretion, shall establish all other provisions relating to meetings of
    Holders of Securities, including notice of the time, place or purpose of
    any meeting at which any matter is to be voted on by any Holders of
    Securities, waiver of any such notice, action by consent without a meeting,
    the establishment of a record date, quorum requirements, voting in person
    or by proxy or any other matter with respect to the exercise of any such
    right to vote.

                           8.60% PREFERRED SECURITIES
                             8.60% COMMON SECURITIES



          Pursuant to Section 7.1 of the Amended and Restated Declaration of
Trust, dated as of July 24, 1996 (as amended from time to time, the
"Declaration"), the designation, rights, privileges, restrictions, preferences
and other terms and provisions of the Preferred Securities and the Common
Securities are set out below (each capitalized term used but not defined herein
has the meaning set forth in the Declaration or, if not defined in such
Declaration, as defined in the Prospectus referred to below):

          1.   DESIGNATION AND NUMBER.

          (a)  PREFERRED SECURITIES.  One Million Nine Hundered Forty Thousand
(1,940,000) Preferred Securities of the Trust with an aggregate liquidation
amount with respect to the assets of the Trust of Fourty Eight Million Five
Hundred Thousand dollars ($48,500,000) and a liquidation amount with respect to
the assets of the Trust of $25 per preferred security, are hereby designated for
the purposes of identification only as "8.60% Trust Originated Preferred
Securities" (the "Preferred Securities").  The Preferred Security Certificates
evidencing the Preferred Securities shall be substantially in the form of
Exhibit A-1 to the Declaration, with such changes and additions thereto or
deletions therefrom as may be required by ordinary usage, custom or practice or
to conform to the rules of any stock exchange on which the Preferred Securities
are listed.

          (b)  COMMON SECURITIES.  60,000 Common Securities of the Trust with an
aggregate liquidation amount with respect to the assets of the Trust of One
Million Five Hundred Thousand dollars ($1,500,000) and a liquidation amount with
respect to the assets of the Trust of $25 per common security, are hereby
designated for the purposes of identification only as "8.60% Trust Originated
Common Securities" (the "Common Securities").  The Common Security Certificates
evidencing the Common Securities shall be substantially in the form of Exhibit
A-2 to the Declaration, with such changes and additions thereto or deletions
therefrom as may be required by ordinary usage, custom or practice.

          2.   DISTRIBUTIONS.

          (a)  Distributions payable on each Security will be fixed at a rate
per annum of 8.60% (the "Coupon Rate") of the stated liquidation amount of $25
per Security, such rate being the rate of interest payable on the Debentures to
be held by the Institutional Trustee.  Distributions in arrears for more than
one quarter will bear interest thereon compounded quarterly at the Coupon Rate
(to the extent permitted by applicable law).  The term "Distributions" as used
herein includes such cash distributions and any such interest payable unless
otherwise stated.  A Distribution is payable only to the extent that payments
are made in respect of the Debentures held by the Institutional Trustee and to
the extent the Institutional Trustee has funds available therefor.  The amount
of Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year of twelve 30-day months, and
for any period shorter than a full quarterly Distribution period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed per 90-day quarter.

          (b)  Distributions on the Securities will be cumulative, will accrue
from July 29, 1996, and will be payable quarterly in arrears, on March 31, June
30, September 30 and December 31 of each year, commencing on September 30, 1996,
except as otherwise described below.  The Debenture Issuer has the right under
the Indenture to defer payments of interest by extending the interest payment
period from time to time on the Debentures for a period not exceeding 20
consecutive quarters or extend beyond the maturity date of the Debentures (each
an "Extension Period"), during which Extension Period no interest shall be due
and payable on the Debentures, PROVIDED THAT no Extension Period shall last
beyond the date of maturity of the Debentures.  As a consequence of such
deferral, Distributions will also be deferred.  Despite such deferral, quarterly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded quarterly during any
such Extension Period.  Prior to the termination of any such Extension Period,
the Debenture Issuer may further extend such Extension Period; PROVIDED THAT
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarters or extend beyond the maturity of
the Debentures.  Payments of accrued Distributions will be payable to Holders as
they appear on the books and records of the Trust on the first record date after
the end of the Extension Period.  Upon the termination of any Extension Period
and the payment of all amounts then due, the Debenture Issuer may commence a new
Extension Period, subject to the above requirements.

          (c)  Distributions on the Securities will be payable to the Holders
thereof as they appear on the books and records of the Trust on the relevant
record dates.  While the Preferred Securities remain in book-entry only form,
the relevant record dates shall be one Business Day prior to the relevant
payment dates which payment dates correspond to the interest payment dates on
the Debentures.  Subject to any applicable laws and regulations and the
provisions of the Declaration, each such payment in respect of the Preferred
Securities will be made as described under the heading "Description of the
Preferred Securities -- Book-Entry Only Issuance -- The Depository Trust
Company" in the Prospectus dated July 24, 1996 (the


                                       I-2
<PAGE>


"Prospectus") of the Trust included in the Registration Statement on Form S-3 of
the Sponsor and the Trust.  The relevant record dates for the Common Securities
shall be the same record date as for the Preferred Securities.  If the Preferred
Securities shall not continue to remain in book-entry only form, the relevant
record dates for the Preferred Securities, shall conform to the rules of any
securities exchange on which the securities are listed and, if none, shall be
selected by the Regular Trustees, which dates shall be at least one Business Day
but less than 60 Business Days before the relevant payment dates, which payment
dates correspond to the interest payment dates on the Debentures.  Distributions
payable on any Securities that are not punctually paid on any Distribution
payment date, as a result of the Debenture Issuer having failed to make a
payment under the Debentures, will cease to be payable to the Person in whose
name such Securities are registered on the relevant record date, and such
defaulted Distribution will instead be payable to the Person in whose name such
Securities are registered on the special record date or other specified date
determined in accordance with the Indenture.  If any date on which Distributions
are payable on the Securities is not a Business Day, then payment of the
Distribution payable on such date will be made on the next succeeding day that
is a Business Day (and without any interest or other payment in respect of any
such delay) except that, if such Business Day is in the next succeeding calendar
year, such payment shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on such date.

          (d)  In the event that there is any money or other property held by or
for the Trust that is not accounted for hereunder, such property shall be
distributed Pro Rata (as defined herein) among the Holders of the Securities.

          3.   LIQUIDATION DISTRIBUTION UPON DISSOLUTION.

          In the event of any voluntary or involuntary dissolution, winding-up
or termination of the Trust, the Holders of the Securities on the date of the
dissolution, winding-up or termination, as the case may be, will be entitled to
receive out of the assets of the Trust available for distribution to Holders of
Securities after satisfaction of liabilities of creditors an amount equal to the
aggregate of the stated liquidation amount of $25 per Security plus accrued and
unpaid Distributions thereon to the date of payment (such amount being the
"Liquidation Distribution"), unless, in connection with such dissolution,
winding-up or termination, Debentures in an aggregate stated principal amount
equal to the aggregate stated liquidation amount of such Securities, with an
interest rate equal to the Coupon Rate of, and bearing accrued and unpaid
interest in an amount equal to the accrued and unpaid Distributions on, such
Securities, shall be distributed on a Pro Rata basis to the Holders of the
Securities in exchange for such Securities.

          If, upon any such dissolution, the Liquidation Distribution can be
paid only in part because the Trust has insufficient assets available to pay in
full the aggregate Liquidation Distribution, then the amounts payable directly
by the Trust on the Securities shall be paid on a Pro Rata basis.

          4.   REDEMPTION AND DISTRIBUTION.

          (a)  Upon the repayment of the Debentures in whole or in part, whether
at maturity or upon redemption (either at the option of the Debenture Issuer or
pursuant to a Tax Event as described below), the proceeds from such repayment or
payment shall be simultaneously applied to redeem Securities having an aggregate
liquidation amount equal to the aggregate principal amount of the Debentures so
repaid or redeemed at a redemption price of $25 per Security plus an amount
equal to accrued and unpaid Distributions thereon at the date of the redemption,
payable in cash  as set forth below (the "Redemption Price").  Holders will be
given not less than 30 nor more than 60 days' notice of such redemption.

          (b)  If fewer than all the outstanding Securities are to be so
redeemed, the Common Securities and the Preferred Securities will be redeemed
Pro Rata and the Preferred Securities to be redeemed will be as described in
Section 4(f)(ii) below.

          (c)  If, at any time, a Tax Event shall occur and be continuing the
Regular Trustees shall, except in certain limited circumstances in relation to a
Tax Event described in this Section 4(c), dissolve the Trust and, after
satisfaction of creditors, cause Debentures held by the Institutional Trustee,
having an aggregate principal amount equal to the aggregate stated liquidation
amount of, with an interest rate identical to the Coupon Rate of, and accrued
and unpaid interest equal to accrued and unpaid Distributions on, and having the
same record date for payment as the Securities, to be distributed to the Holders
of the Securities in liquidation of such Holders' interests in the Trust on a
Pro Rata basis, within 90 days following the occurrence of such Tax Event (the
"90 Day Period"); PROVIDED, HOWEVER, that, as a condition of such dissolution
and distribution, the Regular Trustees shall have received an opinion of a
nationally recognized independent tax counsel experienced in such matters (a "No
Recognition Opinion"), which opinion may rely on published revenue rulings of
the Internal Revenue Service, to the effect that the Holders of the Securities
will not recognize any gain or loss for United States federal income tax
purposes as a result of the dissolution of the Trust and the distribution of
Debentures, and PROVIDED, FURTHER, that, if at the time there is available to
the Debenture Issuer the opportunity to eliminate, within the 90 Day Period, the
Tax Event by taking some ministerial action, such as filing a form or making an
election, or pursuing some other similar reasonable measure that has no adverse
effect on the Trust, the Debenture Issuer, the Sponsor or the Holders of the
Securities ("Ministerial Action"), the Debenture Issuer will pursue such
Ministerial Action in lieu of dissolution.

          If in the event of a Tax Event (i) after receipt of a Tax Event
Opinion (as defined hereinafter) by the Regular Trustees, the Debenture Issuer
has received an opinion (a "Redemption Tax Opinion") of a nationally recognized
independent tax counsel experienced in such matters that, as a result of a Tax
Event, there is more than an insubstantial risk that the Debenture Issuer would
be precluded from deducting the interest on the Debentures for United States
federal income tax purposes even after the Debentures were distributed to the
Holders of Securities in liquidation of such Holders' interests in the Trust as
described in this Section 4(c), or (ii) the Regular Trustees shall have been
informed by such tax counsel that a No Recognition Opin-



                                       I-4
<PAGE>

ion cannot be delivered to the Trust, the Debenture Issuer shall have the right
at any time, upon not less than 30 nor more than 60 days' notice, to redeem the
Debentures in whole or in part for cash within 90 days following the occurrence
of such Tax Event, and, following such redemption, Securities with an aggregate
liquidation amount equal to the aggregate principal amount of the Debentures so
redeemed shall be redeemed by the Trust at the Redemption Price on a Pro Rata
basis; PROVIDED, HOWEVER, that, if at the time there is available to the
Debenture Issuer or the Trust the opportunity to eliminate, within such 90 day
period, the Tax Event by taking some Ministerial Action, the Trust or the
Debenture Issuer will pursue such Ministerial Action in lieu of redemption.

          "Tax Event" means that the Regular Trustees shall have received an
opinion of a nationally recognized independent tax counsel experienced in such
matters (a "Dissolution Tax Opinion") to the effect that on or after the date of
the Prospectus, as a result of (a) any amendment to, clarification of, or change
(including any announced prospective change) in the laws (or any regulations
thereunder) of the United States or any political subdivision or taxing
authority thereof or therein affecting taxation, (b) any judicial decision,
official administrative pronouncement, ruling, regulatory procedure, notice or
announcement, including any notice or announcement of intent to adopt such
procedures or regulations (an "Administrative Action") or (c) any amendment to,
clarification of, or change in the official position or the interpretation of
such Administrative Action or judicial decision that differs from the
theretofore generally accepted position, in each case, by any legislative body,
court, governmental authority or regulatory body, irrespective of the manner in
which such amendment, clarification or change is made known, which amendment,
clarification, or change is effective or such pronouncement or decision is
announced, in each case, on or after, the first date of issuance of the
Securities, there is more than an insubstantial risk that (i) the Trust is or
will be within 90 days of the date thereof, subject to United States federal
income tax with respect to interest accrued or received on the Debentures, (ii)
the Trust is, or will be within 90 days of the date thereof, subject to more
than a de minimis amount of taxes, duties or other governmental charges, or
(iii) interest payable in cash by the Debenture Issuer to the Trust on the
Debentures is not, or within 90 days of the date thereof will not be,
deductible, in whole or in part, by the Debenture Issuer for United States
federal income tax purposes.

          On and from the date fixed by the Regular Trustees for any
distribution of Debentures upon dissolution of the Trust:  (i) the Securities
will no longer be deemed to be outstanding, (ii) The Depository Trust Company
(the "Depository") or its nominee (or any successor Clearing Agency or its
nominee), as the record Holder of the Preferred Securities, will receive a
registered global certificate or certificates representing the Debentures to be
delivered upon such distribution, and (iii) any certificates representing
Securities, except for certificates representing Preferred Securities held by
the Depository or its nominee (or any successor Clearing Agency or its nominee),
will be deemed to represent Debentures having an aggregate principal amount
equal to the aggregate stated liquidation amount of, with an interest rate
identical to the Coupon Rate of, and accrued and unpaid interest equal to
accrued and unpaid Distributions on such Preferred Securities until such
certificates are presented to the Debenture Issuer or its agent for transfer or
reissue.



                                       I-5

          (d)  The Trust may not redeem fewer than all the outstanding
Securities unless all accrued and unpaid Distributions have been paid on all
Securities for all quarterly Distribution periods terminating on or before the
date of redemption.

          (e)  If the Debentures are distributed to holders of the Securities,
pursuant to the terms of the Indenture, the Debenture Issuer will use its best
efforts to have the Debentures listed on the New York Stock Exchange or on such
other exchange as the Preferred Securities were listed immediately prior to the
distribution of the Debentures.

          (f)  "Redemption or Distribution Procedures for Redemption by the
Trust."

          (i)  Notice of any redemption of, or notice of distribution of
     Debentures in exchange for the Securities (a "Redemption/Distribution
     Notice") will be given by the Trust by mail to each Holder of Securities to
     be redeemed or exchanged not fewer than 30 nor more than 60 days before the
     date fixed for redemption or exchange thereof which, in the case of a
     redemption, will be the date fixed for redemption of the Debentures.  For
     purposes of the calculation of the date of redemption or exchange and the
     dates on which notices are given pursuant to this Section 4(f)(i), a
     Redemption/ Distribution Notice shall be deemed to be given on the day such
     notice is first mailed by first-class mail, postage prepaid, to Holders of
     Securities.  Each Redemption/Distribution Notice shall be addressed to the
     Holders of Securities at the address of each such Holder appearing in the
     books and records of the Trust.  No defect in the Redemption/Distribution
     Notice or in the mailing of either thereof with respect to any Holder shall
     affect the validity of the redemption or exchange proceedings with respect
     to any other Holder.

          (ii) In the event that fewer than all the outstanding Securities are
     to be redeemed, the Securities to be redeemed shall be redeemed Pro Rata
     from each Holder of Preferred Securities, it being understood that, in
     respect of Preferred Securities registered in the name of and held of
     record by the Depository or its nominee (or any successor Clearing Agency
     or its nominee) or any nominee, the distribution of the proceeds of such
     redemption will be made to each Clearing Agency Participant (or Person on
     whose behalf such nominee holds such securities) in accordance with the
     procedures applied by such agency or nominee.

          (iii)     If Securities are to be redeemed and the Trust gives a
     Redemption/Distribution Notice, which notice may only be issued if the
     Debentures are redeemed as set out in this Section 4 (which notice will be
     irrevocable), then (A) while the Preferred Securities are in book-entry
     only form, with respect to the Preferred Securities, by 12:00 noon, New
     York City time, on the redemption date, provided that the Debenture Issuer
     has paid the Institutional Trustee by 10:00 A.M., New York City time a
     sufficient amount of cash in connection with the related redemption or
     maturity of the Debentures, the Institutional Trustee will deposit
     irrevocably with the Depository or its nominee (or successor Clearing
     Agency or its nominee) funds sufficient to pay the applicable Redemption
     Price with respect to the Preferred Securities and will give the Depos-


                                       I-6
<PAGE>

     itory irrevocable instructions and authority to pay the Redemption Price to
     the Holders of the Preferred Securities, and (B) with respect to Preferred
     Securities issued in definitive form and Common Securities, provided that
     the Debenture Issuer has paid the Institutional Trustee a sufficient amount
     of cash in connection with the related redemption or maturity of the
     Debentures, the Institutional Trustee will pay the relevant Redemption
     Price to the Holders of such Securities by check mailed to the address of
     the relevant Holder appearing on the books and records of the Trust on the
     redemption date.  If a Redemption/Distribution Notice shall have been given
     and funds deposited as required, if applicable, then immediately prior to
     the close of business on the date of such deposit, or on the redemption
     date, as applicable, distributions will cease to accrue on the Securities
     so called for redemption and all rights of Holders of such Securities so
     called for redemption will cease, except the right of the Holders of such
     Securities to receive the Redemption Price, but without interest on such
     Redemption Price.  Neither the Regular Trustees nor the Trust shall be
     required to register or cause to be registered the transfer of any
     Securities that have been so called for redemption.  If any date fixed for
     redemption of Securities is not a Business Day, then payment of the
     Redemption Price payable on such date will be made on the next succeeding
     day that is a Business Day (and without any interest or other payment in
     respect of any such delay) except that, if such Business Day falls in the
     next calendar year, such payment will be made on the immediately preceding
     Business Day, in each case with the same force and effect as if made on
     such date fixed for redemption.  If payment of the Redemption Price in
     respect of any Securities is improperly withheld or refused and not paid
     either by the Institutional Trustee or by the Sponsor as guarantor pursuant
     to the relevant Securities Guarantee, Distributions on such Securities will
     continue to accrue from the original redemption date to the actual date of
     payment, in which case the actual payment date will be considered the date
     fixed for redemption for purposes of calculating the Redemption Price.

          (iv) Redemption/Distribution Notices shall be sent by the Regular
     Trustees on behalf of the Trust to (A) in respect of the Preferred
     Securities, the Depository or its nominee (or any successor Clearing Agency
     or its nominee) if the Global Certificates have been issued or, if
     Definitive Preferred Security Certificates have been issued, to the Holder
     thereof, and (B) in respect of the Common Securities to the Holder thereof.


          (v)  Subject to the foregoing and applicable law (including, without
     limitation, United States federal securities laws), provided the acquiror
     is not the Holder of the Common Securities or the obligor under the
     Indenture, the Sponsor or any of its subsidiaries may at any time and from
     time to time purchase outstanding Preferred Securities by tender, in the
     open market or by private agreement.

               5.   VOTING RIGHTS - PREFERRED SECURITIES.

          (a)  Except as provided under Sections 5(b) and 7 and as otherwise
required by law and the Declaration, the Holders of the Preferred Securities
will have no voting rights.


                                       I-7
<PAGE>


          (b)  Subject to the requirements set forth in this paragraph, the
Holders of a majority in aggregate liquidation amount of the Preferred
Securities, voting separately as a class, may direct the time, method, and place
of conducting any proceeding for any remedy available to the Institutional
Trustee, or exercising any trust or power conferred upon the Institutional
Trustee under the Declaration, including the right to direct the Institutional
Trustee, as holder of the Debentures, to (i) exercise the remedies available
under the Indenture with respect to the Debentures, (ii) waive any past default
and its consequences that is waivable under Section 6.6 of the Indenture, or
(iii) exercise any right to rescind or annul a declaration that the principal of
all the Debentures shall be due and payable, PROVIDED, HOWEVER, that, where a
consent under the Indenture would require the consent or act of the Holders of
greater than a majority of the Holders in principal amount of Debentures
affected thereby, (a "Super Majority"), the Institutional Trustee may only give
such consent or take such action at the written direction of the Holders of at
least the proportion in liquidation amount of the Preferred Securities which the
relevant Super Majority represents of the aggregate principal amount of the
Debentures outstanding.  The Institutional Trustee shall not revoke any action
previously authorized or approved by a vote of the Holders of the Preferred
Securities.  Other than with respect to directing the time, method and place of
conducting any remedy available to the Institutional Trustee or the Debenture
Trustee as set forth above, the Institutional Trustee shall not take any action
in accordance with the directions of the Holders of the Preferred Securities
under this paragraph unless the Institutional Trustee has obtained an opinion of
tax counsel to the effect that for the purposes of United States federal income
tax the Trust will not be classified as other than a grantor trust on account of
such action.  If a Declaration Event of Default has occurred and is continuing
and such event is attributable to the failure of the Debenture Issuer to pay
interest or principal on the Debentures on the date such interest or principal
is otherwise payable (or in the case of redemption, on the redemption date),
then a holder of Preferred Securities may directly institute a proceeding for
enforcement of payment to such Holder of the principal of or interest on the
Debentures having a principal amount equal to the aggregate liquidation amount
of the Preferred Securities of such holder (a "Direct Action") on or after the
respective due date specified in the Debentures.  In connection with such Direct
Action, the rights of the holders of the Common Securities Holder will be
subrogated to the rights of such holder of Preferred Securities to the extent of
any payment made by the Issuer to such holder of Preferred Securities in such
Direct Action.  Except as provided in the preceding sentences, the Holders of
Preferred Securities will not be able to exercise directly any other remedy
available to the holders of the Debentures.

          Any approval or direction of Holders of Preferred Securities may be
given at a separate meeting of Holders of Preferred Securities convened for such
purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent.  The Regular Trustees will cause a notice of any
meeting at which Holders of Preferred Securities are entitled to vote, or of any
matter upon which action by written consent of such Holders is to be taken, to
be mailed to each Holder of record of Preferred Securities.  Each such notice
will include a statement setting forth (i) the date of such meeting or the date
by which such action is to be taken, (ii) a description of any resolution
proposed for adoption at such meeting on which such

                                       I-8

<PAGE>

Holders are entitled to vote or of such matter upon which written consent is
sought and (iii) instructions for the delivery of proxies or consents.

          No vote or consent of the Holders of the Preferred Securities will be
required for the Trust to redeem and cancel Preferred Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

          Notwithstanding that Holders of Preferred Securities are entitled to
vote or consent under any of the circumstances described above, any of the
Preferred Securities that are owned by the Sponsor or any Affiliate of the
Sponsor shall not be entitled to vote or consent and shall, for purposes of such
vote or consent, be treated as if they were not outstanding.

          6.   VOTING RIGHTS - COMMON SECURITIES.

          (a)  Except as provided under Sections 7(b), (c) and 8 and as
otherwise required by law and the Declaration, the Holders of the Common
Securities will have no voting rights.

          (b)  The Holders of the Common Securities are entitled, in accordance
with Article V of the Declaration, to vote to appoint, remove or replace any
Trustee or to increase or decrease the number of Trustees.

          (c)  Subject to Section 2.6 of the Declaration and only after the
Event of Default with respect to the Preferred Securities has been cured,
waived, or otherwise eliminated and subject to the requirements of the second to
last sentence of this paragraph, the Holders of a Majority in liquidation amount
of the Common Securities, voting separately as a class, may direct the time,
method, and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or exercising any trust or power conferred upon the
Institutional Trustee under the Declaration, including (i) directing the time,
method, place of conducting any proceeding for any remedy available to the
Debenture Trustee, or exercising any trust or power conferred on the Debenture
Trustee with respect to the Debentures, (ii) waive any past default and its
consequences that is waivable under Section 6.6 of the Indenture, or (iii)
exercise any right to rescind or annul a declaration that the principal of all
the Debentures shall be due and payable, PROVIDED THAT, where a consent or
action under the Indenture would require the consent or act of the Holders of
greater than a majority in principal amount of Debentures affected thereby (a
"Super Majority"), the Institutional Trustee may only give such consent or take
such action at the written direction of the Holders of at least the proportion
in liquidation amount of the Common Securities which the relevant Super Majority
represents of the aggregate principal amount of the Debentures outstanding.
Pursuant to this Section 6(c), the Institutional Trustee shall not revoke any
action previously authorized or approved by a vote of the Holders of the
Preferred Securities.  Other than with respect to directing the time, method and
place of conducting any remedy available to the Institutional Trustee or the
Debenture Trustee as set forth above, the Institutional Trustee shall not take
any action in accordance with the directions of the Holders of the Common
Securities under this paragraph unless the Institutional Trustee has


                                       I-9
<PAGE>


received an opinion of tax counsel to the effect that for the purposes of United
States federal income tax the Trust will not be classified as other than a
grantor trust on account of such action.  If the Institutional Trustee fails to
enforce its rights under the Declaration, any Holder of Common Securities may
institute a legal proceeding directly against any Person to enforce the
Institutional Trustee's rights under the Declaration, without first instituting
a legal proceeding against the Institutional Trustee or any other Person.

          Any approval or direction of Holders of Common Securities may be given
at a separate meeting of Holders of Common Securities convened for such purpose,
at a meeting of all of the Holders of Securities in the Trust or pursuant to
written consent.  The Regular Trustees will cause a notice of any meeting at
which Holders of Common Securities are entitled to vote, or of any matter upon
which action by written consent of such Holders is to be taken, to be mailed to
each Holder of record of Common Securities.  Each such notice will include a
statement setting forth (i) the date of such meeting or the date by which such
action is to be taken, (ii) a description of any resolution proposed for
adoption at such meeting on which such Holders are entitled to vote or of such
matter upon which written consent is sought and (iii) instructions for the
delivery of proxies or consents.

          No vote or consent of the Holders of the Common Securities will be
required for the Trust to redeem and cancel Common Securities or to distribute
the Debentures in accordance with the Declaration and the terms of the
Securities.

          7.   AMENDMENTS TO DECLARATION AND INDENTURE.

          (a)  In addition to any requirements under Section 12.1 of the
Declaration, if any proposed amendment to the Declaration provides for, or the
Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than as described in
Section 8.1 of the Declaration, then the Holders of outstanding Securities
voting together as a single class, will be entitled to vote on such amendment or
proposal (but not on any other amendment or proposal) and such amendment or
proposal shall not be effective except with the approval of the Holders of at
least a Majority in liquidation amount of the Securities affected thereby;
provided, however, if any amendment or proposal referred to in clause (i) above
would adversely affect only the Preferred Securities or only the Common
Securities, then only the affected class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of a Majority in liquidation amount of such class of
Securities.

          (b)  In the event the consent of the Institutional Trustee as the
holder of the Debentures is required under the Indenture with respect to any
amendment, modification or termination on the Indenture or the Debentures, the
Institutional Trustee shall request the written direction of the Holders of the
Securities with respect to such amendment, modification or termination and shall
vote with respect to such amendment, modification or termination as direct-


                                      I-10
<PAGE>

ed by a Majority in liquidation amount of the Securities voting together as a
single class; PROVIDED, HOWEVER, that where a consent under the Indenture would
require the consent of the holders of greater than a majority in aggregate
principal amount of the Debentures (a "Super Majority"), the Institutional
Trustee may only give such consent at the direction of the Holders of at least
the proportion in liquidation amount of the Securities which the relevant Super
Majority represents of the aggregate principal amount of the Debentures
outstanding; PROVIDED, FURTHER, that the Institutional Trustee shall not take
any action in accordance with the directions of the Holders of the Securities
under this Section 7(b) unless the Institutional Trustee has received an opinion
of tax counsel to the effect that for the purposes of United States federal
income tax the Trust will not be classified as other than a grantor trust on
account of such action.

          8.   PRO RATA.

          A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder
of Securities according to the aggregate liquidation amount of the Securities
held by the relevant Holder in relation to the aggregate liquidation amount of
all Securities outstanding unless, in relation to a payment, an Event of Default
under the Declaration has occurred and is continuing, in which case any funds
available to make such payment shall be paid first to each Holder of the
Preferred Securities pro rata according to the aggregate liquidation amount of
Preferred Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Preferred Securities outstanding, and only after
satisfaction of all amounts owed to the Holders of the Preferred Securities, to
each Holder of Common Securities pro rata according to the aggregate liquidation
amount of Common Securities held by the relevant Holder relative to the
aggregate liquidation amount of all Common Securities outstanding.

          9.   RANKING.

          The Preferred Securities rank PARI PASSU and payment thereon shall be
made Pro Rata with the Common Securities except that, where a Declaration Event
of Default occurs and is continuing, the rights of Holders of the Common
Securities to payment in respect of Distributions and payments upon liquidation,
redemption and otherwise are subordinated to the rights to payment of the
Holders of the Preferred Securities.

          10.  LISTING.

          The Regular Trustees shall use their best efforts to cause the
Preferred Securities to be listed for quotation on the New York Stock Exchange,
Inc.

          11.  ACCEPTANCE OF SECURITIES GUARANTEE AND INDENTURE.

          Each Holder of Preferred Securities and Common Securities, by the
acceptance thereof, agrees to the provisions of the Preferred Securities
Guarantee and the Common


                                      I-11

Securities Guarantee, respectively, including the subordination provisions
therein and to the provisions of the Indenture.

          12.  NO PREEMPTIVE RIGHTS.

          The Holders of the Securities shall have no preemptive rights to
subscribe for any additional securities.

          13.  MISCELLANEOUS.

          These terms constitute a part of the Declaration.

          The Sponsor will provide a copy of the Declaration, the Preferred
Securities Guarantee or the Common Securities Guarantee (as may be appropriate),
and the Indenture to a Holder without charge on written request to the Sponsor
at its principal place of business.

<PAGE>

                          [FORM OF REVERSE OF SECURITY]

          Distributions payable on each Preferred Security will be fixed at a
rate per annum of 8.60% (the "Coupon Rate") of the stated liquidation amount of
$25 per Preferred Security, such rate being the rate of interest payable on the
Debentures to be held by the Institutional Trustee.  Distributions in arrears
for more than one quarter will bear interest thereon compounded quarterly at the
Coupon Rate (to the extent permitted by applicable law).  The term
"Distributions" as used herein includes such cash distributions and any such
interest payable unless otherwise stated.  A Distribution is payable only to the
extent that payments are made in respect of the Debentures held by the
Institutional Trustee and to the extent the Institutional Trustee has funds
available therefor.  The amount of Distributions payable for any period will be
computed for any full quarterly Distribution period on the basis of a 360-day
year of twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 30-day month.

          Except as otherwise described below, distributions on the Preferred
Securities will be cumulative, will accrue from the date of original issuance
and will be payable quarterly in arrears, on March 31, June 30, September 30 and
December 31 of each year, commencing on September 30, 1996, to [Holders of
record fifteen (15) days prior to such payment dates, which payment dates shall
correspond to the interest payment dates on the Debentures.]  The Debenture
Issuer has the right under the Indenture to defer payments of interest by
extending the interest payment period from time to time on the Debentures for a
period not exceeding 20 consecutive quarters (each an "Extension Period")
provided that no Extension Period shall last beyond the date of the maturity of
the Debentures and, as a consequence of such deferral, Distributions will also
be deferred.  Despite such deferral, quarterly Distributions will continue to
accrue with interest thereon (to the extent permitted by applicable law) at the
Coupon Rate compounded quarterly during any such Extension Period. Prior to the
termination of any such Extension Period, the Debenture Issuer may further
extend such Extension Period; PROVIDED THAT such Extension Period together with
all such previous and further extensions thereof may not exceed 20 consecutive
quarters or extend beyond the maturity of the Debentures.  Payments of accrued
Distributions will be payable to Holders as they appear on the books and records
of the Trust on the first record date after the end of the Extension Period.
Upon the termination of any Extension Period and the payment of all amounts then
due, the Debenture Issuer may commence a new Extension Period, subject to the
above requirements.

          The Preferred Securities shall be redeemable as provided in the
Declaration.

          The Preferred Securities shall be convertible into shares of Debenture
Issuer Common Stock, through (i) the exchange of Preferred Securities for a
portion of the Debentures and (ii) the immediate conversion of such Debentures
into Debenture Issuer Common Stock, in the manner and according to the terms set
forth in the Declaration.

that any Security of a particular series or portion thereof is called for
redemption and the redemption date is subsequent to a regular record date with
respect to any Interest Payment Date and prior to such Interest Payment Date,
interest on such Security will be paid upon presentation and surrender of such
Security as provided in Section 3.3.

          Any interest on any Security that is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date for Security of the same
series (herein called "Defaulted Interest") shall forthwith cease to be payable
to the registered holder on the relevant


                                      9



<PAGE>



regular record date by virtue of having been such holder; and such Defaulted
Interest shall be paid by the Company, at its election, as provided in clause
(1) or clause (2) below:

          (1) The Company may make payment of any Defaulted Interest on
     Securities to the Persons in whose names such Securities (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 such Security 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 not be more than 15 nor 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 Securityholder at his or her address as it
     appears in the Security Register (as hereinafter defined), not less than 10
     days prior to such special record date.  Notice of the proposed payment of
     such Defaulted Interest and the special record date therefor having been
     mailed as aforesaid, such Defaulted Interest shall be paid to the Persons
     in whose names such Securities (or their respective Predecessor Securities)
     are registered on such special record date and shall be no longer payable
     pursuant to the following clause (2).

          (2) The Company may make payment of any Defaulted Interest on any
     Securities 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 Trustees of the proposed payment
     pursuant to this clause, such manner of payment shall be deemed practicable
     by the Trustee.

          Unless otherwise set forth in a Board Resolution of the Company or one
or more indentures supplemental hereto establishing the terms of any series of
Securities pursuant to Section 2.1 hereof, the term "regular record date" as
used in this Section with respect to a series of Securities with respect to any
Interest Payment Date for such series shall mean either the fifteenth day of the
month immediately preceding the month in which an Interest Payment Date
established for such series pursuant to Section 2.1 hereof shall occur, if such
Interest Payment Date is the first day of a month, or the last day of the month
immediately preceding the month in which an Interest Payment Date established 
for such series pursuant to Section 2.1 hereof


                                      10



<PAGE>



shall occur, if such Interest Payment Date is the fifteenth day of a month,
whether or not such date is a Business Day.

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

          SECTION 2.4.   EXECUTION AND AUTHENTICATIONS.

          The Debt Securities shall be signed on behalf of the Company by its
President or one of its Vice Presidents, under its corporate seal attested by
its Secretary or one of its Assistant Secretaries.  Signatures may be in the
form of a manual or facsimile signature.  The Company may use the facsimile
signature of any Person who shall have been a President or Vice President
thereof, or of any Person who shall have been a Secretary or Assistant Secretary
thereof, notwithstanding the fact that at the time the Securities shall be
authenticated and delivered or disposed of such Person shall have ceased to be
the President or a Vice President, or the Secretary or an Assistant Secretary,
of the Company.  The seal of the Company may be in the form of a facsimile of
such seal and may be impressed, affixed, imprinted or otherwise reproduced on
the Securities.  The Securities may contain such notations, legends or
endorsements required by law, stock exchange rule or usage.  Each Security shall
be dated the date of its authentication by the Trustee.

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

          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 written order of the
Company for the authentication and delivery of such Securities, signed by its
President or any Vice President and its Treasurer or any Assistant Treasurer,
and the Trustee in accordance with such written order shall authenticate and
deliver such 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 7.1) shall be
fully protected in relying upon, an Opinion of Counsel stating that the form and
terms thereof have been established in conformity with the provisions of this
Indenture.

          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 that is not reasonably acceptable to the
Trustee.

          SECTION 2.5.   REGISTRATION OF TRANSFER AND EXCHANGE.

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

          (b) The Company shall keep, or cause to be kept, at its office or
agency designated for such purpose in the Borough of Manhattan, the City and
State of New York, or such other location designated by the Company a register
or registers (herein referred to as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Company shall register
the Securities and the transfers of Securities as in this Article provided and
which at all reasonable times shall be open for inspection by the Trustee.  The
registrar for the purpose of registering Securities and transfer of Securities
as herein provided shall be appointed as authorized by Board Resolution (the
"Security Registrar").

          Upon surrender for transfer of any Security at the office or agency of
the Company designated for such purpose, the Company shall execute, the Trustee
shall authenticate and such office or agency shall deliver in the name of the
transferee or transferees a new Security or Securities of the same series as the
Security presented for a like aggregate principal amount.

          All Securities presented or surrendered for exchange or registration
of transfer, as provided in this Section, shall be accompanied (if so required
by the Company or the Security Registrar) by a written instrument or instruments
of transfer, in form satisfactory to the Company or the Security Registrar, duly
executed by the registered holder or by such holder's duly authorized attorney
in writing.

          (c) No service charge shall be made for any exchange or registration
of transfer of Securities, or issue of new Securities in case of partial
redemption of any series, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge in relation thereto,
other than exchanges pursuant to Section 2.6, the second paragraph of Section
3.3 and Section 9.4 not involving any transfer.

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


                                      12

The provisions of this Section 2.5 are, with respect to any Global Security,
subject to Section 2.11 hereof.

          SECTION 2.6.   TEMPORARY SECURITIES.

          Pending the preparation of definitive Securities of any series, the
Company may execute, and the Trustee shall authenticate and deliver, temporary
Securities (printed, lithographed or typewritten) of any authorized
denomination.  Such temporary Securities shall be substantially in the form of
the definitive Securities in lieu of which they are issued, but with such
omissions, insertions and variations as may be appropriate for temporary
Securities, all as may be determined by the Company.  Every temporary Security
of any series shall be executed by the Company and be authenticated by the
Trustee upon the same conditions and in substantially the same manner, and with
like effect, as the definitive Securities of such series.  Without unnecessary
delay the Company will execute and will furnish definitive Securities of such
series and thereupon any or all temporary Securities of such series may be
surrendered in exchange therefor (without charge to the holders), at the office
or agency of the Company designated for the purpose in the Borough of Manhattan,
the City and State of New York, and the Trustee shall authenticate and such
office or agency shall deliver in exchange for such temporary Securities an
equal aggregate principal amount of definitive Securities of such series, unless
the Company advises the Trustee to the effect that definitive Securities need
not be executed and furnished until further notice from the Company.  Until so
exchanged, the temporary Securities of such series shall be entitled to the same
benefits under this Indenture as definitive Securities of such series
authenticated and delivered hereunder.

          SECTION 2.7.   MUTILATED, DESTROYED, LOST OR STOLEN SECURITIES.

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


                                      13



<PAGE>



Company and the Trustee such security or indemnity as they may require to save
them harmless, and, in case of destruction, loss or theft, evidence to the
satisfaction of the Company and the Trustee of the destruction, loss or theft of
such Security and of the ownership thereof.

          Every replacement Security issued pursuant to the provisions of this
Section shall constitute an additional contractual obligation of the Company
whether or not the mutilated, destroyed, lost or stolen Security shall be found
at any time, or be enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other
Securities of the same series duly issued hereunder.  All Securities shall be
held and owned upon the express condition that the foregoing provisions are
exclusive with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities, and shall preclude (to the extent lawful) any and all
other rights \or remedies, notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement or payment of
negotiable instruments or other securities without their surrender.


                                      14



<PAGE>



          SECTION 2.8.   CANCELLATION.

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

          SECTION 2.9.   BENEFIT OF INDENTURE.

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

          SECTION 2.10.  AUTHENTICATING AGENT.

          So long as any of the Securities of any series remain Outstanding
there may be an Authenticating Agent for any or all such series of Securities
which the Trustee shall have the right to appoint.  Said Authenticating Agent
shall be authorized to act on behalf of the Trustee to authenticate Securities
of such series issued upon exchange, transfer or partial redemption thereof, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder.  All references in this Indenture to the authentication of
Securities by the Trustee shall be deemed to include authentication by an
Authenticating Agent for such series.  Each Authenticating Agent shall be
acceptable to the Company and shall be a corporation that has a combined capital
and surplus, as most recently reported or determined by it, sufficient under the
laws of any jurisdiction under which it is organized or in which it is doing
business to conduct a trust business, and that is otherwise authorized under
such laws to conduct such business and is subject to supervision or examination
by Federal or State authorities.  If at any time any Authenticating Agent shall
cease to be eligible in accordance with these provisions, it shall resign
immediately.

          Any Authenticating Agent may at any time resign by giving written
notice of resignation to the Trustee and to the Company.  The Trustee may at any
time (and upon request by the Company shall) terminate the agency of any
Authenticating Agent by giving written notice


                                      15



<PAGE>



of termination to such Authenticating Agent and to the Company.  Upon 
resignation, termination or cessation of eligibility of any Authenticating 
Agent, the Trustee may appoint an eligible successor Authenticating Agent 
acceptable to the Company.  Any successor Authenticating Agent, upon acceptance
of its appointment hereunder, shall become vested with all the rights, powers 
and duties of its predecessor hereunder as if originally named as an 
Authenticating Agent pursuant hereto.

          SECTION 2.11.  GLOBAL SECURITIES.

          (a) If the Company shall establish pursuant to Section 2.1 that the
Securities of a particular series are to be issued as a Global Security, then
the Company shall execute and the Trustee shall, in accordance with Section 2.4,
authenticate and deliver, a Global Security that (i) shall represent, and shall
be denominated in an amount equal to the aggregate principal amount of, all of
the Outstanding Securities of such series, (ii) shall be registered in the name
of the Depositary or its nominee, (iii) shall be delivered by the Trustee to the
Depositary or pursuant to the Depositary's instruction and (iv) shall bear a
legend substantially to the following effect: "Except as otherwise provided in
Section 2.11 of the Indenture, this Security may be transferred, in whole but
not in part, only to another nominee of the Depositary or to a successor
Depositary or to a nominee of such successor Depositary."

          (b) Notwithstanding the provisions of Section 2.5, the Global Security
of a series may be transferred, in whole but not in part and in the manner
provided in Section 2.5, only to another nominee of the Depositary for such
series, or to a successor Depositary for such series selected or approved by the
Company or to a nominee of such successor Depositary.

          (c) If at any time the Depositary for a series of the Securities
notifies the Company that it is unwilling or unable to continue as Depositary
for such series or if at any time the Depositary for such series shall no longer
be registered or in good standing under the Exchange Act, or other applicable
statute or regulation, and a successor Depositary for such series is not
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such condition, as the case may be, this Section 2.11 shall
no longer be applicable to the Securities of such series and the Company will
execute, and subject to Section 2.5, the Trustee will authenticate and deliver
the Securities of such series in definitive registered form without coupons, in
authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Security of such series in exchange for such
Global Security.  In addition, the Company may at any time determine that the
Securities of any series shall no longer be represented by a Global Security and
that the provisions of this Section 2.11 shall no longer apply to the Securities
of such series.  In such event the Company will execute and subject to Section
2.5, the Trustee, upon receipt of an Officers, Certificate evidencing such
determination by the Company, will authenticate and deliver the Securities of
such series in definitive registered form without coupons, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Security of such series in exchange for such Global
Security.  Upon the exchange of the Global Security for such Securities in
definitive registered form without coupons, in authorized denominations, the
Global Security 


                                      16



<PAGE>



shall be cancelled by the Trustee.  Such Securities in definitive registered 
form issued in exchange for the Global Security pursuant to this Section 2.11(c)
shall be registered in such names and in such authorized denominations as the 
Depositary, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee.  The Trustee shall deliver such 
Securities to the Depositary for delivery to the Persons in whose names such 
Securities are so registered.

                                  ARTICLE III.

            REDEMPTION OF DEBT SECURITIES AND SINKING FUND PROVISIONS

          SECTION 3.1.   REDEMPTION.

          The Company may redeem the Debt Securities of any series issued
hereunder on and after the dates and in accordance with the terms established
for such series pursuant to Section 2.1 hereof.

          SECTION 3.2.   NOTICE OF REDEMPTION.

          (a) In case the Company shall desire to exercise such right to redeem
all or, as the case may be, a portion of the Debt Securities of any series in
accordance with the right reserved so to do, the Company shall, or shall cause
the Trustee to, give notice of such redemption to holders of the Debt Securities
of such series to be redeemed by mailing, first class postage prepaid, a notice
of such redemption not less than 30 days and not more than 90 days before the
date fixed for redemption of that series to such holders at their last addresses
as they shall appear upon the Security Register unless a shorter period is
specified in the Debt Securities to be redeemed.  Any notice that is mailed in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the registered holder receives the notice.  In any case,
failure duly to give such notice to the holder of any Security of any series
designated for redemption in whole or in part, or any defect in the notice,
shall not affect the validity of the proceedings for the redemption of any other
Debt Securities of such series or any other series.  In the case of any
redemption of Debt Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Debt Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with any such restriction.

          Each such notice of redemption shall specify the date fixed for
redemption and the redemption price at which Debt Securities of that series are
to be redeemed, and shall state that payment of the redemption price of such
Debt Securities to be redeemed will be made at the office or agency of the
Company in the Borough of Manhattan, the City and State of New York, upon
presentation and surrender of such Debt Securities, that interest accrued to the
date fixed for redemption will be paid as specified in said notice, that from
and after said date interest will cease to accrue and that the redemption is for
a sinking fund, if such is the case.  If less than all the Debt Securities of a
series are to be redeemed, the notice to the holders of Debt 


                                      17



<PAGE>



Securities of that series to be redeemed in whole or in part shall specify the
particular Debt Securities to be so redeemed.  In case any Security is to be 
redeemed in part only, the notice that relates to such Security shall state the
portion of the principal amount thereof to be redeemed, and shall state that on
and after the redemption date, upon surrender of such Security, a new Security 
or Debt Securities of such series in principal amount equal to the unredeemed 
portion thereof. 

          (b) If less than all the Debt Securities of a series are to be
redeemed, the Company shall give the Trustee at least 45 days' notice in advance
of the date fixed for redemption as to the aggregate principal amount of Debt
Securities of the series to be redeemed, and thereupon the Trustee shall select,
by lot or in such other manner as it shall deem appropriate and fair in its
discretion and that may provide for the selection of a portion or portions
(equal to twenty-five U.S. dollars ($25) or any integral multiple thereof) of
the principal amount of such Debt Securities of a denomination larger than $25,
the Debt Securities to be redeemed and shall thereafter promptly notify the
Company in writing of the numbers of the Debt Securities to be redeemed, in
whole or in part.

          The Company may, if and whenever it shall so elect, by delivery of
instructions signed on its behalf by its President or any Vice President,
instruct the Trustee or any paying agent to call all or any part of the Debt
Securities of a particular series for redemption and to give notice of
redemption in the manner set forth in this Section, such notice to be in the
name of the Company or its own name as the Trustee or such paying agent may deem
advisable.  In any case in which notice of redemption is to be given by the
Trustee or any such paying agent, the Company shall deliver or cause to be
delivered to, or permit to remain with, the Trustee or such paying agent, as the
case may be, such Security Register, transfer books or other records, or
suitable copies or extracts therefrom, sufficient to enable the Trustee or such
paying agent to give any notice by mail that may be required under the
provisions of this Section.

          SECTION 3.3.   PAYMENT UPON REDEMPTION.

          (a) If the giving of notice of redemption shall have been completed as
above provided, the Debt Securities or portions of Debt Securities of the series
to be redeemed specified in such notice shall become due and payable on the date
and at the place stated in such notice at the applicable redemption price,
together with interest accrued to the date fixed for redemption and interest on
such Debt Securities or portions of Debt Securities shall cease to accrue on and
after the date fixed for redemption, unless the Company shall default in the
payment of such redemption price and accrued interest with respect to any such
Security or portion thereof.  On presentation and surrender of such Debt
Securities on or after the date fixed for redemption at the place of payment
specified in the notice, said Debt Securities shall be paid and redeemed at the
applicable redemption price for such series, together with interest accrued
thereon to the date fixed for redemption (but if the date fixed for redemption
is an interest payment date, the interest installment payable on such date shall
be payable to the registered holder at the close of business on the applicable
record date pursuant to Section 2.3).


                                      18



<PAGE>



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

          SECTION 3.4.   SINKING FUND.

          The provisions of Sections 3.4, 3.5 and 3.6 shall be applicable to any
sinking fund for the retirement of Debt Securities of a series, except as
otherwise specified as contemplated by Section 2.1 for Debt Securities of such 
series.

          The minimum amount of any sinking fund payment provided for by the
terms of Debt 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 Debt Securities of any series is herein referred to as an
"optional sinking fund payment".  If provided for by the terms of Debt
Securities of any series, the cash amount of any sinking fund payment may be
subject to reduction as provided in Section 3.5. Each sinking fund payment shall
be applied to the redemption of Debt Securities of any series as provided for by
the terms of Debt Securities of such series.

          SECTION 3.5.   SATISFACTION OF SINKING FUND PAYMENTS WITH DEBT
                         SECURITIES.

          The Company (i) may deliver outstanding Debt Securities of a series
(other than any Debt Securities previously called for redemption) and (ii) may
apply as a credit Debt Securities of a series that have been redeemed either at
the election of the Company pursuant to the terms of such Debt Securities or
through the application of permitted optional sinking fund payments pursuant to
the terms of such Debt Securities, in each case in satisfaction of all or any
part of any sinking fund payment with respect to the Debt Securities of such
series required to be made pursuant to the terms of such Debt Securities as
provided for by the terms of such series, PROVIDED that such Debt Securities
have not been previously so credited.  Such Debt Securities shall be received
and credited for such purpose by the Trustee at the redemption price specified
in such Debt Securities for redemption through operation of the sinking fund and
the amount of such sinking fund payment shall be reduced accordingly.

          SECTION 3.6.   REDEMPTION OF DEBT SECURITIES FOR SINKING FUND.

          Not less than 45 days prior to each sinking fund payment date for any
series of Debt 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 the series, the portion thereof, if any,
that is to be satisfied by delivering and crediting Debt Securities of that
series pursuant to Section 3.5 and the basis for such credit and will, together
with such Officers' Certificate, deliver to the Trustee any Debt Securities to
be so delivered.  Not less

the Debt Securities to be redeemed upon such sinking fund payment date in the 
manner specified in Section 3.2 and cause notice of the redemption thereof to be
given in the name of and at the expense of the Company in the manner provided in
Section 3.2.  Such notice having been duly given, the redemption of such Debt
Securities shall be made upon the terms and in the manner stated in Section 3.3.


                                   ARTICLE IV.

          SECTION 4.1.   PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

          The Company will duly and punctually pay or cause to be paid the
principal of (and premium, if any) and interest on the Debt Securities of that
series at the time and place and in the manner provided herein and established
with respect to such Debt Securities.

          SECTION 4.2.   MAINTENANCE OR AGENCY.

          So long as any series of the Securities remain Outstanding, the
Company agrees to maintain an office or agency in the Borough of Manhattan, the
City and State of New York, with respect to each such series and at such other
location or locations as may be designated as provided in this Section 4.2,
where (i) Securities of that series may be presented for payment, (ii)
Securities of that series may be presented as hereinabove authorized for
registration of transfer and exchange, and (iii) notices and demands to or upon
the Company in respect of the Securities of that series and this Indenture may
be given or served, such designation to continue with respect to such office or
agency until the Company shall, by written notice signed by its President or a
Vice President and delivered to the trustee, designate some other office or
agency for such purposes or any of them.  If at any time the Company shall fail
to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, notices and demands may be
made or served at the Corporate Trust Office of the Trustee, and the Company
hereby appoints the Trustee as its agent to receive all such presentations,
notices and demands.

          SECTION 4.3.   PAYING AGENTS.

          (a) If the Company shall appoint one or more paying agents for all or
any series of the Securities, other than the Trustee, the Company will cause
each such paying agent to execute and deliver to the Trustee an instrument in
which such agent shall agree with the Trustee, subject to the provisions of this
Section:

          (1) that it will hold all sums held by it as such agent for the
     payment of the principal of (and premium, if any) or interest on the
     Securities of that series (whether such sums have been paid to it by the
     Company or by any other obligor of such Securities) in trust for the
     benefit of the Persons entitled thereto;


                                      20



<PAGE>



          (2) that it will give the Trustee notice of any failure by the Company
     (or by any other obligor of such Securities) to make any payment of the
     principal of (and premium, if any) or interest on the Securities of that
     series when the same shall be due and payable;

          (3) that it will, at any time during the continuance of any failure
     referred to in the preceding paragraph (a)(2) above, upon the written
     request of the Trustee, forthwith pay to the Trustee all sums so held in
     trust by such paying agent; and

          (4) that it will perform all other duties of paying agent as set forth
     in this Indenture.

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

          (c) Notwithstanding anything in this Section to the contrary, (i) the
agreement to hold sums in trust as provided in this Section is subject to the
provisions of Section 11.5, and (ii) the Company may at any time, for the
purpose of obtaining the satisfaction and discharge of this Indenture or for any
other purpose, pay, or direct any paying agent to pay, to the Trustee all sums
held in trust by the Company or such paying agent, such sums to be held by the
Trustee upon the same terms and conditions as those upon which such sums were
held by the Company or such paying agent; and, upon such payment by any paying
agent to the Trustee, such paying agent shall be released from all further
liability with respect to such money.

          SECTION 4.4.   APPOINTMENT TO FILL VACANCY IN OFFICE OF TRUSTEE.

          The Company, whenever necessary to avoid or fill a vacancy in the
office of Trustee, will appoint, in the manner provided in Section 7.10, a
Trustee, so that there shall at all times be a Trustee hereunder.

          SECTION 4.5.   COMPLIANCE WITH CONSOLIDATION PROVISIONS.

          The Company will not, while any of the Securities remain Outstanding,
consolidate with, or merge into, or merge into itself, or sell or convey all or
substantially all of its property to any other company unless the provisions of
Article Ten hereof are complied with.

          SECTION 4.6.   LIMITATION ON DIVIDENDS; TRANSACTIONS WITH AFFILIATES.

            If Securities are issued to a Sierra Pacific Trust or a trustee of
such trust in connection with the issuance of Trust Securities by such Sierra
Pacific Trust and (i) there shall have occurred any event that would constitute
an Event of Default, (ii) Sierra Pacific shall be in default with respect to its
payment of any obligations under the Preferred Securities Guarantee or Common
Securities Guarantee relating to such Sierra Pacific Trust or (iii) the Company
shall have given notice of its election to defer payments of interest on such
Securities by extending the interest payment period as provided in the Indenture
and such period, or any extension thereof, shall be continuing, then (a) the
Company shall not declare or pay any dividends on, make any distributions with
respect to, or redeem, purchase or make a liquidation payment with respect to,
any of its capital stock (other than stock dividends paid by the Company which
consist of the same class as that on which the dividend is being paid), (b) the
Company shall not make any payment of interest, principal or premium, if any, on
or repay, repurchase or redeem any debt securities issued by the Company which
rank pari passu with or Junior to such Securities, and (c) shall not make any
guarantee payment with respect to the foregoing (other than pursuant to the
Guarantee).

          SECTION 4.7.   COVENANTS AS TO SIERRA PACIFIC TRUSTS. 

          In the event Securities are issued to a Sierra Pacific Trust or a
trustee of such trust in connection with the issuance of Trust Securities by
such Sierra Pacific Trust, for so long as such Trust Securities remain
outstanding, the Company will (i) maintain 100% direct or indirect ownership of
the Common Securities of such Sierra Pacific Trust; PROVIDED, however, that any
permitted successor of the Company under the Indenture may succeed to the
Company's ownership of the Common Securities, and (ii) use its reasonable
efforts to cause such Sierra Pacific Trust (a) to remain a statutory business
trust, except in connection with a distribution of Securities, the redemption of
all of the Trust Securities of such Sierra Pacific Trust or certain mergers,
consolidations or amalgamations, each as permitted by the Declaration of such
Sierra Pacific Trust, and (b) to otherwise continue not to be treated as an
association taxable as a corporation or partnership for United States federal
income tax purposes.

          (1) the Company defaults in the payment of any installment of interest
     upon any of the Securities of that series, as and when the same shall
     become due and payable, and continuance of such default for a period of 30
     days; PROVIDED, however, that a valid extension of an interest payment
     period by the Company in accordance with the terms of any indenture
     supplemental hereto, shall not constitute a default in the payment of
     interest for this purpose;

          (2) the Company defaults in the payment of the principal of (or
     premium, if any, on) any of the Securities of that series as and when the
     same shall become due and payable whether at maturity, upon redemption, by
     declaration or otherwise, or in any payment required by any sinking or
     analogous fund established with respect to that series; PROVIDED, HOWEVER,
     that a valid extension of the maturity of such Securities in accordance
     with the terms of any indenture supplemental hereto shall not constitute a
     default in the payment of principal or premium, if any;

          (3) if applicable to the Securities of that series, failure by the
     Company to issue Sierra Pacific Common Stock upon an election by the Holder
     or Holders of such Debt Securities to convert such Debt Securities into
     shares of Sierra Pacific Common Stock pursuant to the supplemental
     indenture, Board Resolution or other instrument authorizing such series of
     Securities;

          (4) the Company fails to observe or perform any other of its covenants
     or agreements with respect to that series contained in this Indenture or
     otherwise established with respect to that series of Securities pursuant to
     Section 2.1 hereof (other than a covenant or agreement that has been
     expressly included in this Indenture solely for the benefit of one or more
     series of Securities other than such series) for a period of 90 days after
     the date on which written notice of such failure, requiring the same to be
     remedied and stating that such notice is a "Notice of Default" hereunder,
     shall have been given to the Company by the Trustee, by registered or
     certified mail, or to the Company and the Trustee by the holders of at
     least 25% in principal amount of the Securities of that series at the time
     Outstanding;

          (5) the Company pursuant to or within the meaning of any Bankruptcy
     Law (i) commences a voluntary case, (ii) consents to the entry of an order
     for relief against it in an involuntary case, (iii) consents to the
     appointment of a Custodian of it or for all or substantially all of its
     property or (iv) makes a general assignment for the benefit of its
     creditors;

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

                                      25



<PAGE>



          (7) in the event Securities are issued to a Sierra Pacific Trust or a
     trustee of such trust in connection with the issuance of Trust Securities
     by such Sierra Pacific Trust, such Sierra Pacific Trust shall have
     voluntarily or involuntarily dissolved, wound-up its business or otherwise
     terminated its existence except in connection with (i) the distribution of
     Securities to holders of Trust Securities in liquidation of their interests
     in such Sierra Pacific Trust, (ii) the redemption of all of the outstanding
     Trust Securities of such Sierra Pacific Trust or (iii) certain mergers,
     consolidations or amalgamation, each as permitted by the Declaration of
     such Sierra Pacific Trust.

          (b) In each and every such case, unless the principal of all the
Securities of that series shall have already become due and payable, either the
Trustee or the holders of not less than 25% in aggregate principal amount of the
Securities of that series then Outstanding hereunder, by notice in writing to
the Company (and to the Trustee if given by such Securityholders), may declare
the principal of all the Securities of that series to be due and payable
immediately, and upon any such declaration the same shall become and shall be
immediately due and payable, notwithstanding anything contained in this
Indenture or in the Securities of that series or established with respect to
that series pursuant to Section 2.1 to the contrary.

          (c) At any time after the principal of the Securities of that series
shall have been so declared due and payable, and before any judgment or decree
for the payment of the moneys due shall have been obtained or entered as
hereinafter provided, the holders of a majority in aggregate principal amount of
the Securities of that series then Outstanding hereunder, by written notice to
the Company and the Trustee, may rescind and annul such declaration and its
consequences if: (i) the Company has paid or deposited with the Trustee a sum
sufficient to pay all matured installments of interest upon all the Securities
of that series and the principal of (and premium, if any, on) any and all
Securities of that series that shall have become due otherwise than by
acceleration (with interest upon such principal and premium, if any, and, to the
extent that such payment is enforceable under applicable law, upon overdue
installments of interest, at the rate per annum expressed in the Securities of
that series to the date of such payment or deposit) and the amount payable to
the Trustee under Section 7.6, and (ii) any and all Events of Default under the
Indenture with respect to such series, other than the nonpayment of principal on
Securities of that series that shall not have become due by their terms, shall
have been remedied or waived as provided in Section 6.6.

          No such rescission and annulment shall extend to or shall affect any
subsequent default or impair any right consequent thereon.

          (d) In case the Trustee shall have proceeded to enforce any right with
respect to Securities of that series under this Indenture and such proceedings
shall have been discontinued or abandoned because of such rescission or
annulment or for any other reason or shall have been determined adversely to the
Trustee, then and in every such case the Company and the Trustee shall be
restored respectively to their former positions and rights hereunder, and all
rights,


                                      26



<PAGE>



remedies and powers of the Company and the Trustee shall continue as though no
such proceedings had been taken.

          SECTION 6.2.   COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
                         TRUSTEE.

          (a) The Company covenants that (1) in case it shall default in the
payment of any installment of interest on any of the Securities of a series, or
any payment required by any sinking or analogous fund established with respect
to that series as and when the same shall have become due and payable, and such
default shall have continued for a period of 90 Business Days, or (2) in case it
shall default in the payment of the principal of (or premium, if any, on) any of
the Securities of a series when the same shall have become due and payable,
whether upon maturity of the Securities of a series or upon redemption or upon
declaration or otherwise, then, upon demand of the Trustee or the Guarantor will
pay to the Trustee, for the benefit of the holders of the Securities of that
series, the whole amount that then shall have been become due and payable on all
such Securities for principal (and premium, if any) or interest, or both, as the
case may be, with interest upon the overdue principal (and premium, if any) and
(to the extent that payment of such interest is enforceable under applicable law
and, if the Securities are held by a Sierra Pacific Trust or a trustee of such
trust, without duplication of any other amounts paid by such Sierra Pacific
Trust or trustee in respect thereof) upon overdue installments of interest at
the rate per annum expressed in the Securities of that series; and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, and the amount payable to the Trustee under Section 7.6.

          (b) If the Company shall fail to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any action or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or other obligor upon the
Securities of that series and collect the moneys adjudged or decreed to be
payable in the manner provided by law out of the property of the Company or
other obligor upon the Securities of that series, wherever situated.

          (c) In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, readjustment, arrangement, composition or judicial proceedings
affected the Company or the creditors or property of either, the Trustee shall
have power to intervene in such proceedings and take any action therein that may
be permitted by the court and shall (except as may be otherwise provided by law)
be entitled to file such proofs of claim and other papers and documents as may
be necessary or advisable in order to have the claims of the Trustee and of the
holders of Securities of such series allowed for the entire amount due and
payable by the Company under the Indenture at the date of institution of such
proceedings and for any additional amount that may become due and payable by the
Company after such date, and to collect and receive any moneys or other property
payable or deliverable on any such claim, and to distribute the same after the
deduction of the amount payable to the Trustee under Section 7.6; and any


                                      27



<PAGE>

receiver, assignee or trustee in bankruptcy or reorganization is hereby
authorized by each of the holders of Securities of such series to make such
payments to the Trustee, and, in the event that the Trustee shall consent to the
making of such payments directly to such Securityholders, to pay to the Trustee
any amount due it under Section 7.6.

          (d) All rights of action and of asserting claims under this Indenture,
or under any of the terms established with respect to Securities of that series,
may be enforced by the Trustee without the possession of any of such Securities,
or the production thereof at any trial or other proceeding relative thereto, and
any such suit or proceeding instituted by the Trustee shall be brought in its
own name as trustee of an express trust, and any recovery of judgment shall,
after provision for payment to the Trustee of any amounts due under Section 7.6,
be for the ratable benefit of the holders of the Securities of such series.

          In case of an Event of Default hereunder, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in the Indenture or in aid of the exercise
of any power granted in this Indenture, or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

          Nothing contained herein shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Securityholder any
plan of reorganization, arrangement, adjustment or composition affecting the
Securities of that series or the rights of any holder thereof or to authorize
the Trustee to vote in respect of the claim of any Securityholder in any such
proceeding.

          SECTION 6.3.   APPLICATION OF MONEYS COLLECTED.

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

          FIRST: To the payment of costs and expenses of collection and of all
     amounts payable to the Trustee under Section 7.6;

          SECOND: To the payment of all Senior Indebtedness of the Company if
     and to the extent required by Article Fourteen; and

          THIRD: To the payment of the amounts then due and unpaid upon
     Securities of such series for principal (and premium, if any) and interest,
     in respect of which or for the benefit of which such money has been
     collected, ratably, without preference or 


                                      28



<PAGE>



     priority of any kind, according to the amounts due and payable on such 
     Securities for principal (and premium, if any) and interest, respectively.

          SECTION 6.4.   LIMITATION ON SUITS.

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

          Notwithstanding anything contained herein to the contrary or  any
other provisions of this Indenture, the right of any holder of any Security to
receive payment of the principal of (and premium, if any) and interest on such
Security, as therein provided, on or after the respective due dates expressed in
such Security (or in the case of redemption, on the redemption date), or to
institute suit for the enforcement of any such payment on or after such
respective dates or redemption date, shall not be impaired or affected without
the consent of such holder and by accepting a Security hereunder it is expressly
understood, intended and covenanted by the taker and holder of every Security of
such series with every other such taker and holder and the Trustee, that no one
or more holders of Securities of such series shall have any right in any manner
whatsoever by virtue or by availing of any provision of this Indenture to
affect, disturb or prejudice the rights of the holders of any other of such
Securities, or to obtain or seek to obtain priority over or preference to any
other such holder, or to enforce any right under this Indenture, except in the
manner herein provided and for the equal, ratable and common benefit of all
holders of Securities of series.  For the protection and enforcement of the
provisions of this Section, each and every Securityholder and the Trustee shall
be entitled to such relief as can be given either at law or in equity.

          SECTION 6.5.   RIGHTS AND REMEDIES CUMULATIVE; DELAY OR OMISSION NOT
                         WAIVER.

          (a) Except as otherwise provided in Section 2.7, all powers and
remedies given by this Article to the Trustee or to the Securityholders shall,
to the extent permitted by law, be deemed cumulative and not exclusive of any
other powers and remedies available to the Trustee or the holders of the
Securities, by judicial proceedings or otherwise, to enforce the performance 


                                      29



<PAGE>



or observance of the covenants and agreements contained in this Indenture or
otherwise established with respect to such Securities.

          (b) No delay or omission of the Trustee or of any holder of any of the
Securities to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or on acquiescence
therein; and, subject to the provisions of Section 6.4, every power and remedy
given by this Article or by law to the Trustee or the Securityholders may be
exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Securityholders.

          SECTION 6.6.   CONTROL BY SECURITYHOLDERS.

          The holders of a majority in aggregate principal amount of the
Securities of any series at the time Outstanding, determined in accordance with
Section 8.4, shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee with respect to such series;
PROVIDED, HOWEVER, that such direction shall not be in conflict with any rule of
law or with this Indenture or be unduly prejudicial to the rights of holders of
Securities of any other series at the time Outstanding determined in accordance
with Section 8.4.  Subject to the provisions of Section 7.1, the Trustee shall
have the right to decline to follow any such direction if the Trustee in good
faith shall, by a Responsible Officer or Officers of the Trustee, determine that
the proceeding so directed would involve the Trustee in personal liability.  The
holders of a majority in aggregate principal amount of the Securities of any
series at the time Outstanding affected thereby, determined in accordance with
Section 8.4, may on behalf of the holders of all of the Securities of such
series waive any past default in the performance of any of the covenants
contained herein or established pursuant to Section 2.1 with respect to such
series and its consequences, except (i) a default in the payment of the
principal of, or premium, if any, or interest on, any of the Securities of that
series as and when the same shall become due by the terms of such Securities
otherwise than by acceleration (unless such default has been cured and a sum
sufficient to pay all matured installments of interest and principal and any
premium has been deposited with the Trustee (in accordance with Section 6.1(c)),
(ii) a default in the covenants contained in Section 4.6 or (iii) 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; PROVIDED, HOWEVER, that if the Debt Securities of such series
are held by a Sierra Pacific Trust or a trustee of such trust, such waiver or
modification to such waiver shall not be effective until the holders of a
majority in liquidation preference of Trust Securities of the applicable Sierra
Pacific Trust shall have consented to such waiver or modification to such
waiver; PROVIDED FURTHER, that if the consent of the Holder of each Outstanding
Debt Security is required, such waiver shall not be effective until each holder
of the Trust Securities of the applicable Sierra Pacific Trust shall have
consented to such waiver.  Upon any such waiver, the default covered thereby
shall be deemed to be cured for all purposes of this Indenture and the Company,
the Trustee and the holders of the Securities of such series shall 


                                      30



<PAGE>




be restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other default or impair any right 
consequent thereon.

          SECTION 6.7.   UNDERTAKING TO PAY COSTS.

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


                                  ARTICLE VII.

                             CONCERNING THE TRUSTEE

          SECTION 7.1.   CERTAIN DUTIES AND RESPONSIBILITIES OF TRUSTEE.

          (a) The Trustee prior to the occurrence of an Event of Default with
respect to the Securities of a series and after the curing of all Events of
Default with respect to the Securities of that series that may have occurred,
shall undertake to perform with respect to the Securities of such series such
duties and only such duties as are specifically set forth in this Indenture,and
no implied covenants shall be read into this Indenture against the Trustee.  In
case an Event of Default with respect to the Securities of a series has occurred
(that has not been cured or waived), the Trustee shall exercise with respect to
Securities of that series such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.


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

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


                                      31



<PAGE>



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

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

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

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

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

          SECTION 7.2.   CERTAIN RIGHTS OF TRUSTEE.

          Except as otherwise provided in Section 7.1:

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


                                      32



<PAGE>



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

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

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

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

          (f) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, security, or
other papers or documents, unless requested in writing so to do by the holders
of not less than a majority in principal amount of the Outstanding Securities of
the particular series affected thereby (determined as provided in Section 8.4);
PROVIDED, HOWEVER, that if the payment within a reasonable time to the Trustee
of the costs, expenses or liabilities likely to be incurred by it in the making
of such investigation is, in the opinion of the Trustee, not reasonably assured
to the Trustee by the security afforded to it by the terms of this Indenture,
the Trustee may require reasonable indemnity against such costs, expenses or
liabilities as a condition to so proceeding.  The reasonable expense of every
such examination shall be paid by the Company or, if paid by the Trustee, shall
be repaid by the Company upon demand; and

          (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.

          SECTION 7.3.   TRUSTEE NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OR
                         SECURITIES.

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

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

          (c) The Trustee shall not be accountable for the use or application by
the Company of any of the Securities or of the proceeds of such Securities, or
for the use or application of any moneys paid over by the Trustee in accordance
with any provision of this Indenture or established pursuant to Section 2.1, or
for the use or application of any moneys received by any paying agent other than
the Trustee.

          SECTION 7.4.   MAY HOLD SECURITIES.

          The Trustee or any paying agent or Security Registrar, in its
individual or any other capacity, may become the owner or pledgee of Securities
with the same rights it would have if it were not Trustee, paying agent or
Security Registrar.

          SECTION 7.5.   MONEYS HELD IN TRUST.

          Subject to the provisions of Section 11.5, all moneys received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from other
funds except to the extent required by law.  The Trustee shall be under no
liability for interest on any moneys received by it hereunder except such as it
may agree with the Company to pay thereon.

          SECTION 7.6.   COMPENSATION AND REIMBURSEMENT.

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


                                      34



<PAGE>



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

          (b) The obligations of the Company under this Section to compensate
and indemnify the Trustee and to pay or reimburse the Trustee for expenses,
disbursements and advances shall constitute additional indebtedness hereunder. 
Such additional indebtedness shall be secured by a lien prior to that of the
Securities upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the benefit of the holders of particular
Securities.  If the Trustee incurs expenses or renders services after an Event
of Default occurs, the expenses and the compensation for the services are
intended to constitute expenses of administration under any bankruptcy or
insolvency law applicable to the Company.  

          SECTION 7.7.   RELIANCE ON OFFICERS' CERTIFICATE.

          Except as otherwise provided in Section 7.1, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or
suffering or omitting to take any action hereunder, such matter (unless other
evidence in respect thereof be herein specifically prescribed) may, in the
absence of negligence or bad faith on the part of the Trustee, be deemed to be
conclusively proved and established by an Officers' Certificate delivered to the
Trustee and such certificate, in the absence of negligence or bad faith on the
part of the Trustee, shall be full warrant to the Trustee for any action taken,
suffered or omitted to be taken by it under the provisions of this Indenture
upon the faith thereof.

          SECTION 7.8.   DISQUALIFICATION: CONFLICTING INTERESTS.

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

          SECTION 7.9.   CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

          There shall at all times be a Trustee with respect to the Securities
issued hereunder which shall at all times be a corporation organized and doing
business under the laws of the United States of America or any State or
Territory thereof or of the District of Columbia, or a corporation or other
Person permitted to act as trustee by the Commission, authorized under such laws
to exercise corporate trust powers, having a combined capital and surplus of at
least 50 million U.S. dollars ($50,000,000), and subject to supervision or
examination by Federal, State, Territorial, or District of Columbia authority. 
If such corporation publishes reports of condition at least annually, pursuant
to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.  The
Company may not, nor may any Person 


                                      35



<PAGE>



directly or indirectly controlling, controlled by, or under common control with
the Company, serve as Trustee.  In case at any time the Trustee shall cease to 
be eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 7.10.

          SECTION 7.10.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

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

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

          (1) the Trustee shall fail to comply with the provisions of Section
     7.8 after written request therefor by the Company or the Guarantor or by
     any Securityholder who has been a bona fide holder of a Security or
     Securities for at least six months; or

          (2) the Trustee shall cease to be eligible in accordance with the
     provisions of Section 7.9 and shall fail to resign after written request
     therefor by the Company or by any such Securityholder; or

          (3) the Trustee shall become incapable of acting, or shall be adjudged
     a bankrupt or insolvent, or commence a voluntary bankruptcy proceeding, or
     a receiver of the Trustee or of its property shall be appointed or
     consented to, or any public officer shall take charge or control of the
     Trustee or of its property or affairs for the purpose of rehabilitation,
     conservation or liquidation, 

then, in any such case, the Company may remove the Trustee with respect to all
Securities and appoint a successor trustee by written instrument, in duplicate,
executed by order of the Board of Directors, one copy of which instrument shall
be delivered to the Trustee so removed and one copy to the successor trustee,
or, subject to the provisions of Section 6.8, unless the Trustee's


                                      36



<PAGE>



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

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

          (d) Any resignation or removal of the Trustee and appointment of a
successor trustee with respect to the Securities of a series pursuant to any of
the provisions of this Section shall become effective upon acceptance of
appointment by the successor trustee as provided in Section 7.11.

          (e) Any successor trustee appointed pursuant to this Section may be
appointed with respect to the Securities of one or more series or all of such
series, and at any time there shall be only one Trustee with respect to the
Securities of any particular series.

          SECTION 7.11.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

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

          (b) In case of the appointment hereunder of a successor trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor trustee relates, (2)
shall contain such provisions as shall be deemed necessary or desirable to
confirm that all the rights, powers, trusts and duties of the retiring Trustee
with respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the


                                      37



<PAGE>



provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall 
constitute such Trustees co-trustees of the same trust, that each such Trustee
shall be trustee of a trust or trusts hereunder separate and apart from any 
trust or trusts hereunder administered by any other such Trustee and that no 
Trustee shall be responsible for any act or failure to act on the part of any 
other Trustee hereunder; and upon the execution and delivery of such 
supplemental indenture the resignation or removal of the retiring Trustee shall
become effective to the extent provided therein, such retiring Trustee shall 
with respect to the Securities of that or those series to which the appointment
of such successor trustee relates have no further responsibility for the 
exercise of rights and powers or for the performance of the duties and 
obligations vested in the Trustee under this Indenture, and each such successor
trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Securities of that or those series to which the appointment of such 
successor trustee relates; but, on request of the Company or any successor 
trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor trustee, to the extent contemplated by such supplemental indenture,
the property and money held by such retiring Trustee hereunder with respect to
the Securities of that or those series to which the appointment of such 
successor trustee relates.

          (c) upon request of any such successor trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section, as the case may be.

          (d) 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.

          (e) Upon acceptance of appointment by a successor trustee as provided
in this Section, the Company shall transmit notice of the succession of such
trustee hereunder by mail, first class postage prepaid, to the Securityholders,
as their names and addresses appear upon the Security Register.  If the Company
fails to transmit such notice within ten days after acceptance of appointment by
the successor trustee, the successor trustee shall cause such notice to be
transmitted at the expense of the Company and the Guarantor.

     SECTION 7.12.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder, PROVIDED that such corporation shall be
qualified under the provisions of Section 7.8 and eligible under the provisions
of Section 7.9, without the execution or filing of any paper or any further act
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding.  In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any 


                                      38



<PAGE>



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 7.13.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE COMPANY.

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


                                  ARTICLE VIII.

                         CONCERNING THE SECURITYHOLDERS

          SECTION 8.1.   EVIDENCE OF ACTION BY SECURITYHOLDERS.

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

          If the Company shall solicit from the Securityholders of any series
any request, demand, authorization, direction, notice, consent, waiver or other
action, the Company may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for such series for the determination
of Securityholders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other action, but the Company shall have
no obligation to do so.  If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other action may be given
before or after the record date, but only the Securityholders of record at the
close of business on the record date shall be deemed to be Securityholders for
the purposes of determining whether Securityholders of the requisite proportion
of Outstanding Securities of that series have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other action, and for that purpose the Outstanding Securities of that series
shall be computed as of the record date; PROVIDED, HOWEVER, that no such
authorization, agreement or consent by such Securityholders on the record date
shall be deemed effective unless it shall become effective pursuant to the
provisions of this Indenture not later than six months after the record date.

          SECTION 8.2.   PROOF OF EXECUTION BY SECURITYHOLDERS.

          Subject to the provisions of Section 7.1, proof of the execution of
any instrument by a Securityholder (such proof will not require notarization) or
his agent or proxy and proof of the holding by any Person of any of the
Securities shall be sufficient if made in the following manner:

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

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

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

          SECTION 8.3.   WHO MAY BE DEEMED OWNERS.

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

          SECTION 8.4.   CERTAIN SECURITIES OWNED BY COMPANY DISREGARDED.

          In determining whether the holders of the requisite aggregate
principal amount of Securities of a particular series have concurred in any
direction, consent of waiver under this Indenture, the Securities of that series
that are owned by the Company or any other obligor on the Securities of that
series or by any Person directly or indirectly controlling or controlled by or
under common control with the Company or any other obligor on the Securities of
that series shall be disregarded and deemed not to be Outstanding for the
purpose of any such determination, except that for the purpose of determining
whether the Trustee shall be protected in relying on any such direction, consent
or waiver, only Securities of such series that the Trustee actually knows are so
owned shall be so disregarded.  The Securities so owned that have been pledged
in good faith may be regarded as Outstanding for the purposes of this Section,
if the pledgee shall establish to the satisfaction of the Trustee the pledgee's
right so to act with respect to such Securities and that the pledgee is not a
Person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Company or any such other 


                                      40



<PAGE>



obligor.  In case of a dispute as to such right, any decision by the Trustee 
taken upon the advice of counsel shall be full protection to the Trustee.

          SECTION 8.5.   ACTIONS BINDING ON FUTURE
                         SECURITYHOLDERS.

          At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.1, of the taking of any action by the holders of the
majority or percentage in aggregate principal amount of the Securities of a
particular series specified in this Indenture in connection with such action,
any holder of a Security of that series that is shown by the evidence to be
included in the Securities the holders of which have consented to such action
may, by filing written notice with the Trustee, and upon proof of holding as
provided in Section 8.2, revoke such action so far as concerns such Security. 
Except as aforesaid any such action taken by the holder of any Security shall be
conclusive and binding upon such holder and upon all future holders and owners
of such Security, and of any Security issued in exchange therefor, on
registration of transfer thereof or in place thereof, irrespective of whether or
not any notation in regard thereto is made upon such Security.  Any action taken
by the holders of the majority or percentage in aggregate principal amount of
the Securities of a particular series specified in this Indenture in connection
with such action shall be conclusively binding upon the Company, the Trustee and
the holders of all the Securities of that series.


                                   ARTICLE IX.

                             SUPPLEMENTAL INDENTURES

          SECTION 9.1.   SUPPLEMENTAL INDENTURES WITHOUT THE
                         CONSENT OF SECURITYHOLDERS.

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

          (a) to cure any ambiguity, defect, or inconsistency herein, in the
Securities of any series;

          (b) to comply with Article Ten;

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


                                      41



<PAGE>



          (d) to add to the covenants of the Company for the benefit of the
holders of all or any Series of Securities (and if such covenants are to be for
the benefit of less than all series of Securities, stating that such covenants
are expressly being included solely for the benefit of such series) or to
surrender any right or power herein conferred upon the Company; 

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

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

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

          The Trustee is hereby authorized to join with the Company in the
execution of any such supplemental indenture, and to make any further
appropriate agreements and stipulations that may be therein contained, but the
Trustee shall not be obligated to enter into any such supplemental indenture
that affects the Trustee's own rights, duties or immunities under this Indenture
or otherwise.

          Any supplemental indenture authorized by the provisions of this
Section may be executed by the Company and the Trustee without the consent of
the holders of any of the Securities at the time Outstanding, notwithstanding
any of the provisions of Section 9.2.

          SECTION 9.2.   SUPPLEMENTAL INDENTURES WITH CONSENT OF
                         SECURITYHOLDERS.

          With the consent (evidenced as provided in Section 8.1) of the holders
of not less than a majority in aggregate principal amount of the Securities of
each series affected by such supplemental indenture or indentures at the time
Outstanding, the Company, when authorized by Board Resolutions, and the Trustee
may from time to time and at any time enter into an indenture or indentures
supplemental hereto (which shall conform to the provisions of the Trust
Indenture Act as then in effect) for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or
of any supplemental indenture or of modifying in any manner not covered by
Section 9.1 the rights of the holders of the Securities of such series under
this Indenture; PROVIDED, HOWEVER, that no such supplemental indenture shall
without the consent of the holders of each Debenture then Outstanding and
affected thereby, (i) extend the fixed maturity of any Securities of any series,
or reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any premium payable upon the redemption
thereof, without the consent of the holder of each Security so affected or (ii)
reduce the aforesaid percentage of Securities, the holders of which are required
to consent to any such supplemental indenture PROVIDED, FURTHER, that if the


                                      42



<PAGE>



Debt Securities of such series are held by a Sierra Pacific Trust or a trustee
of such trust, such supplemental indenture shall not be effective until the
holders of a majority in liquidation preference of Trust Securities of the
applicable Trust shall have consented to such supplemental indenture; PROVIDED
FURTHER, that if the consent of the Holder of each Outstanding Debt Security is
required, such supplemental indenture shall not be effective until each holder
of the Trust Securities of the applicable Sierra Pacific Trust shall have
consented to such supplemental indenture.

          It shall not be necessary for the consent of the Securityholders of
any series affected thereby under this Section to approve the particular form of
any proposed supplemental indenture, but it shall be sufficient if such consent
shall approve the substance thereof.

          SECTION 9.3.   EFFECT OF SUPPLEMENTAL INDENTURES.

          Upon the execution of any supplemental indenture pursuant to the
provisions of this Article or of Section 10.1, this Indenture shall, with
respect to such series, be and be deemed to be modified and amended in
accordance therewith and the respective rights, limitations of rights,
obligations, duties and immunities under this Indenture of the Trustee, the
Company and the holders of Securities of the series affected thereby shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

          SECTION 9.4.   SECURITIES AFFECTED BY SUPPLEMENTAL INDENTURES.

          Securities of any series, affected by a supplemental indenture,
authenticated and delivered after the execution of such supplemental indenture
pursuant to the provisions of this Article or of Section 10.1, may bear a
notation in form approved by the Company, provided such form meets the
requirements of any exchange upon which such series may be listed, as to any
matter provided for in such series may be listed, as to any matter provided for
in such supplemental indenture.  If the Company shall so determine, new
Securities of that series so modified as to conform, in the opinion of the Board
of Directors of the Company, to any modification of this Indenture contained in
any such supplemental indenture may be prepared by the Company, authenticated by
the Trustee and delivered in exchange for the Securities of that series then
Outstanding.

          SECTION 9.5.   EXECUTION OF SUPPLEMENTAL INDENTURES.

          Upon the request of the Company, accompanied by their Board
Resolutions authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of Securityholders
required to consent thereto as aforesaid, the Trustee shall join with the
Company in the execution of such supplemental indenture unless such supplemental
indenture affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion but
shall not be obligated 


                                      43



<PAGE>



to enter into such supplemental indenture.  The Trustee, subject to the 
provisions of Section 7.1, may receive an Opinion of Counsel as conclusive 
evidence that any supplemental indenture executed pursuant to this Article is 
authorized or permitted by, and conforms to, the terms of this Article and that
it is proper for the Trustee under the provisions of this Article to join in 
the execution thereof.

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

the case may be, or its successor or successors shall be a party or parties, or
shall prevent any sale, conveyance, transfer or other disposition of the
property of the Company, as the case may be, or its successor or successors as
an entirety, or substantially as an entirety, to any other corporation (whether

successors) authorized to acquire and operate the same; PROVIDED, HOWEVER, the
Company hereby covenants and agree that, upon any such consolidation, merger,
sale, conveyance, transfer or other disposition, the due and punctual payment,
in the case of the Company, of the principal of (premium, if any) and interest
on all of the Debt Securities of all series in accordance with the terms of each
series, according to their tenor and the due and punctual performance and
observance of all the covenants and conditions of this Indenture with respect to

to be kept or performed by the Company as the case may be, shall be expressly
assumed, by supplemental indenture (which shall conform to the provisions of the
Trust Indenture Act, as then in effect) satisfactory in form to the Trustee
executed and delivered to the Trustee by the entity formed by such
consolidation, or into which the Company, as the case may be, shall have been
merged, or by the entity which shall have acquired such property.

substance) may be made in the Securities thereafter to be issued as may be
appropriate.

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

          SECTION 10.3.  EVIDENCE OF CONSOLIDATION, ETC. TO TRUSTEE.

Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale, conveyance, transfer or other disposition, and any such assumption, comply
with the provisions of this Article.

heretofore delivered to the Trustee for cancellation or that have not become due

years after the date upon which the principal of (and premium, if any) or
interest on such Securities shall have respectively become due and payable,

Resolution, and as set forth in an Officers' Certificate, or established in one

(and premium, if any) may be made on the next succeeding Business Day with the
same force and effect as if made on the nominal date of maturity or redemption,

          SECTION 13.9.  CONFLICT WITH TRUST INDENTURE ACT.

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

          SECTION 13.10.  COUNTERPARTS.

          This Indenture may be executed in any number of counterparts, each of

          SECTION 13.11.  SEPARABILITY.

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

          SECTION 13.12.  ASSIGNMENT.

          The Company will have the right at all times to assign any of its

not otherwise be assigned by the parties thereto.

directly against the Company to enforce such Institutional Trustee's rights
under this Indenture without first instituting any legal proceedings against
such Institutional Trustee or any other person or entity.

                                  ARTICLE XIV.

                           SUBORDINATION OF SECURITIES

          SECTION 14.1.  AGREEMENT TO SUBORDINATE.

          The Company covenants and agrees, and each Holder of Debt Securities
issued hereunder by such Holder's acceptance thereof likewise covenants and
agrees, that all Debt Securities shall be issued subject to the provisions of
this Article XIV; and each Holder of a Debt Security, whether upon original
issue or upon transfer or assignment thereof, accepts and agrees to be bound by
such provisions.

          The payment by the Company of the principal of, premium, if any, and
interest on all Debt Securities issued hereunder shall, to the extent and in the
manner hereinafter set forth, be subordinated and junior in right of payment to
the prior payment in full of all Senior Indebtedness of the Company, whether
outstanding at the date of this Indenture or thereafter incurred.

          No provision of this Article XIV shall prevent the occurrence of any
default or Event of Default hereunder.

          SECTION 14.2.  DEFAULT ON SENIOR INDEBTEDNESS.

          In the event and during the continuation of any default by the Company
in the payment of principal, premium, interest or any other payment due on any
Senior Indebtedness of the Company, as the case may be, or in the event that the
maturity of any Senior Indebtedness of the Company, as the case may be, has been
accelerated because of a default, then, in either case, no payment shall be made
by the Company with respect to the principal (including redemption and sinking
fund payments) of, or premium, if any, or interest on the Debt Securities.

          In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee when such payment is prohibited by the preceding
paragraph of this Section 14.3, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing within 90 days of
such payment of the amounts then due and owing on the Senior Indebtedness and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of Senior Indebtedness.

          SECTION 14.3.  LIQUIDATION; DISSOLUTION; BANKRUPTCY.

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

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

          For purposes of this Article XIV, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article XIV with respect
to the Debt Securities to the payment of all Senior Indebtedness of the Company,
as the case may be, that may at the time be outstanding, provided that (i) such
Senior


                                      52



<PAGE>



Indebtedness is assumed by the new corporation, if any, resulting from any such
reorganization or readjustment, and (ii) the rights of the holders of such 
Senior Indebtedness are not, without the consent of such holders, altered
by such reorganization or readjustment.  The consolidation of the Company with,
or the merger of the Company into, another corporation or the liquidation or
dissolution of the Company following the conveyance or transfer of its property
as an entirety, or substantially as an entirety, to another corporation upon the
terms and conditions provided for in Article X of the Indenture shall not be
deemed a dissolution, winding-up, liquidation or reorganization for the purposes
of this Section 14.3 if such other corporation shall, as a part of such
consolidation, merger, conveyance or transfer, comply with the conditions stated
in Article X of the Indenture.  Nothing in Section 14.2 or in this Section 14.3
shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 7.6 of the Indenture.

          SECTION 14.4.  SUBROGATION.

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

          Nothing contained in this Article XIV or elsewhere in the Indenture,
this First Supplemental Indenture or in the Debt Securities is intended to or
shall impair, as between the Company, its creditors other than the holders of
Senior Indebtedness of the Company, and the Holders of the Debt Securities, the
obligation of the Company, which is absolute and unconditional, to pay to the
Holders of the Debt Securities the principal of (and premium, if any) and
interest on the Debt Securities as and when the same shall become due and
payable in accordance with their terms, or is intended to or shall affect the
relative rights of the Holders of the Debt Securities and creditors of the
Company, as the case may be, other than the holders of Senior Indebtedness of
the Company, as the case may be, nor shall anything herein or therein prevent
the Trustee or the Holder of any Debt Security from exercising all remedies
otherwise permitted by applicable law upon default under the Indenture, subject
to the rights, if any, under this Article XIV of the holders of such Senior
Indebtedness in respect of cash, property or securities of the Company, as the
case may be, received upon the exercise of any such remedy.


                                      53



<PAGE>



          Upon any payment or distribution of assets of the Company referred to
in this Article XIV, the Trustee, subject to the provisions of Section 7.1 of
the Indenture, and the Holders of the Debt Securities shall be entitled to
conclusively rely upon any order or decree made by any court of competent
jurisdiction in which such dissolution, winding-up, liquidation or
reorganization proceedings are pending, or a certificate of the receiver,
trustee in bankruptcy, liquidation trustee, agent or other Person making such
payment or distribution, delivered to the Trustee or to the Holders of the Debt
Securities, for the purposes of ascertaining the Persons entitled to participate
in such distribution, the holders of Senior Indebtedness and other indebtedness
of the Company, as the case may be, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article XIV.

          SECTION 14.5.  TRUSTEE TO EFFECTUATE SUBORDINATION.

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

          SECTION 14.6.  NOTICE BY THE COMPANY.

          The Company shall give prompt written notice to a Responsible Officer
of the Trustee of any fact known to the Company that would prohibit the making
of any payment of monies to or by the Trustee in respect of the Debt Securities
pursuant to the provisions of this Article XIV.  Notwithstanding the provisions
of this Article XIV or any other provision of the Indenture and this First
Supplemental Indenture, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment of monies
to or by the Trustee in respect of the Debt Securities pursuant to the
provisions of this Article XIV, unless and until a Responsible Officer of the
Trustee shall have received written notice thereof from the Company or a holder
or holders of Senior Indebtedness or from any trustee therefor; and before the
receipt of any such written notice, the Trustee, subject to the provisions of
Section 7.1 of the Indenture, shall be entitled in all respects to assume that
no such facts exist; PROVIDED, HOWEVER, that if the Trustee shall not have
received the notice provided for in this Section 6.6 at least two Business Days
prior to the date upon which by the terms hereof any money may become payable
for any purpose (including, without limitation, the payment of the principal of
(or premium, if any) or interest on any Debenture), then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such money and to apply the same to the purposes for which
they were received, and shall not be affected by any notice to the contrary that
may be received by it within two Business Days prior to such date.

          The Trustee, subject to the provisions of Section 7.2 of the
Indenture, shall be entitled to conclusively rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness of the Company, as the case may be (or a trustee on behalf of such
holder), to establish that such notice has been given by a holder of such Senior
Indebtedness or a trustee on behalf of any such holder or holders.  In the event
that the Trustee 


                                      54



<PAGE>



determines in good faith that further evidence is required with respect to the 
right of any Person as a holder of such Senior Indebtedness to participate in
any payment or distribution pursuant to this Article XIV, the Trustee may 
request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of such Senior Indebtedness held by such Person, the
extent to which such Person is entitled to participate in such payment or
distribution and any other facts pertinent to the rights of such Person under
this Article XIV, and, if such evidence is not furnished, the Trustee may defer
any payment to such Person pending judicial determination as to the right of
such Person to receive such payment.

          SECTION 14.7.  RIGHTS OF THE TRUSTEE; HOLDERS OF SENIOR INDEBTEDNESS.

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

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

          SECTION 14.8.  SUBORDINATION MAY NOT BE IMPAIRED.

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

          Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness of the Company may, at any time and from time
to time, without the consent of or notice to the Trustee or the Holders of the
Debt Securities, without incurring responsibility to the Holders of the Debt
Securities and without impairing or releasing the subordination provided in this
Article XIV or the obligations hereunder of the Holders of the Debt Securities
to the holders of such Senior Indebtedness, do any one or more of the following:
(i) change the manner, place or terms of payment or extend the time of payment
of, or renew or alter, such Senior Indebtedness, or otherwise amend or
supplement in any manner such Senior Indebtedness or any instrument evidencing
the same or any agreement under which such Senior


                                      55



<PAGE>



Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with
any property pledged, mortgaged or otherwise securing such Senior Indebtedness;
(iii) release any Person liable in any manner for the collection of such Senior
Indebtedness; and (iv) exercise or refrain from exercising any rights against 
the Company, as the case may be, and any other Person.

                                   ARTICLE II

SECTION 2.1.   DESIGNATION AND PRINCIPAL AMOUNT.

<PAGE>


million, which amount shall be as set forth in any written order of the Company
for the authentication and delivery of Debentures pursuant to Section 3.3 of the
Indenture.

SECTION 2.2.   MATURITY.

          The Maturity Date is July 30, 2036.

SECTION 2.3.   FORM AND PAYMENT.

          Except as provided in Section 2.4, the Debentures shall be issued in
fully registered certificated form without interest coupons.  Principal and
interest on the Debentures issued in certificated form will be payable, the
transfer of such Debentures will be registrable and such Debentures will be
exchangeable for Debentures bearing identical terms and provisions at the office
or agency of the Trustee; PROVIDED, HOWEVER, that payment of interest may be
made at the option of the Company by check mailed to the Holder at such address
as shall appear in the Security Register.  Notwithstanding the foregoing, so
long as the Holder of any Debentures is the Institutional Trustee, the payment
of the principal of and interest (including Compounded Interest and Additional
Interest, if any) on such Debentures held by the Institutional Trustee will be
made at such place and to such account as may be designated by the Institutional
Trustee.

SECTION 2.4.   GLOBAL DEBENTURE.

          (a) In connection with a Dissolution Event,

               (i)  the Debentures in certificated form may be presented to the
     Trustee by the Institutional Trustee in exchange for a global Debenture in
     an aggregate principal amount equal to the aggregate principal amount of
     all outstanding Debentures (a "Global Debenture"), to be registered in the
     name of the Depositary, or its nominee, and delivered by the Trustee to the
     Depositary for crediting to the accounts of its participants pursuant to
     the instructions of the Regular Trustees.  The Company upon any such
     presentation shall execute a Global Debenture in such aggregate principal
     amount and deliver the same to the Trustee for authentication and delivery
     in accordance with the Indenture and this First Supplemental Indenture.
     Payments on the Debentures issued as a Global Debenture will be made to the
     Depositary; and

               (ii) if any Preferred Securities are held in non book-entry
     certificated form, the Debentures in certificated form may be presented to
     the Trustee by the Institutional Trustee and any Preferred Security
     Certificate which represents Preferred Securities other than Preferred
     Securities held by the Clearing Agency or its nominee ("Non Book-Entry
     Preferred Securities") will be deemed to represent beneficial interests in
     Debentures presented to the Trustee by the Institutional Trustee having an
     aggregate principal amount equal to the aggregate liquidation amount of the
     Non Book-Entry Preferred Securities until such Preferred Security
     Certificates are presented to the Security Registrar for transfer or
     reissuance at which time such Preferred Security


                                        4
<PAGE>


     Certificates will be cancelled and a Debenture, registered in the name of
     the holder of the Preferred Security Certificate or the transferee of the
     holder of such Preferred Security Certificate, as the case may be, with an
     aggregate principal amount equal to the aggregate liquidation amount of the
     Preferred Security Certificate cancelled, will be executed by the Company
     and delivered to the Trustee for authentication and delivery in accordance
     with the Indenture and this First Supplemental Indenture.  On issue of such
     Debentures, Debentures with an equivalent aggregate principal amount that
     were presented by the Institutional Trustee to the Trustee will be deemed
     to have been cancelled.

          (b)  A Global Debenture may be transferred, in whole but not in part,
only to another nominee of the Depositary, or to a successor Depositary selected
or approved by the Company or to a nominee of such successor Depositary.

          (c)  If at any time the Depositary notifies the Company that it is
unwilling or unable to continue as Depositary or if at any time the Depositary
for such series shall no longer be registered or in good standing under the
Securities Exchange Act of 1934, as amended, or other applicable statute or
regulation, and a successor Depositary for such series is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such condition, as the case may be, the Company will execute, and, subject to
Article III of the Indenture, the Trustee, upon written notice from the Company,
will authenticate and deliver the Debentures in definitive registered form
without coupons, in authorized denominations, and in an aggregate principal
amount equal to the principal amount of the Global Debenture in exchange for
such Global Debenture.  In addition, the Company may at any time determine that
the Debentures shall no longer be represented by a Global Debenture.  In such
event the Company will execute, and subject to Section 3.5 of the Indenture, the
Trustee, upon receipt of an Officers' Certificate evidencing such determination
by the Company, will authenticate and deliver the Debentures in definitive
registered form without coupons, in authorized denominations, and in an
aggregate principal amount equal to the principal amount of the Global Debenture
in exchange for such Global Debenture.  Upon the exchange of the Global
Debenture for such Debentures in definitive registered form without coupons, in
authorized denominations, the Global Debenture shall be cancelled by the
Trustee.  Such Debentures in definitive registered form issued in exchange for
the Global Debenture shall be registered in such names and in such authorized
denominations as the Depositary, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee.  The Trustee
shall deliver such Securities to the Depositary for delivery to the Persons in
whose names such Securities are so registered.

SECTION 2.5.   INTEREST.

          (a)  Each Debenture will bear interest at the rate of 8.60% per annum
(the "Coupon Rate") from the original date of issuance until the principal
thereof becomes due and payable, and on any overdue principal and (to the extent
that payment of such interest is enforceable under applicable law) on any
overdue installment of interest at the Coupon Rate, compounded quarterly,
payable (subject to the provisions of Article Four) quarterly in arrears


                                        5
<PAGE>


on March 31, June 30, September 30 and December 31 of each year (each, an
"Interest Payment Date," commencing on June 30, 1996), to the Person in whose
name such Debenture or any predecessor Debenture is registered, at the close of
business on the regular record date for such interest installment, which, in
respect of any Debentures of which the Institutional Trustee is the Holder of or
a Global Debenture, shall be the close of business on the Business Day next
preceding that Interest Payment Date.  Notwithstanding the foregoing sentence,
if the Preferred Securities are no longer in book-entry only form or, except if
the Debentures are held by the Institutional Trustee, the Debentures are not
represented by a Global Debenture, the Company may select a regular record date
for such interest installment which shall be any date at least one Business Day
before an Interest Payment Date.

          (b)  The amount of interest payable for any period will be computed on
the basis of a 360-day year of twelve 30-day months.  Except as provided in the
following sentence, the amount of interest payable for any period shorter than a
full quarterly period for which interest is computed, will be computed on the
basis of the actual number of days elapsed in such a 30-day period. In the event
that any date on which interest is payable on the Debentures is not a Business
Day, then payment of interest payable on such date will be made on the next
succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date.

          (c)  If, at any time while the Institutional Trustee is the Holder of
any Debentures, the Trust or the Institutional Trustee is required to pay any
taxes, duties, assessments or governmental charges of whatever nature (other
than withholding taxes) imposed by the United States, or any other taxing
authority, then, in any case, the Company will pay as additional interest
("Additional Interest") on the Debentures held by the Institutional Trustee,
such additional amounts as shall be required so that the net amounts received
and retained by the Trust and the Institutional Trustee after paying such taxes,
duties, assessments or other governmental charges will be equal to the amounts
the Trust and the Institutional Trustee would have received had no such taxes,
duties, assessments or other government charges been imposed.

                                   ARTICLE III
                          REDEMPTION OF THE DEBENTURES

SECTION 3.1.   SPECIAL EVENT REDEMPTION.

          If a Tax Event has occurred and is continuing and:

          (a)  the Company has received a Redemption Tax Opinion; or

          (b)  after receiving a Dissolution Tax Opinion, the Regular Trustees
     shall have been informed by tax counsel rendering the Dissolution Tax
     Opinion that a No Recognition Opinion cannot be delivered to the Trust,

then, notwithstanding Section 3.2(a) but subject to Section 3.2(b), the Company
shall have the right upon not less than 30 days nor more than 60 days notice to
the Holders of the Debentures to redeem the Debentures, in whole or in part, for
cash within 90 days following the occurrence of such Tax Event (the "90 Day
Period") at a redemption price equal to 100% of the principal amount to be
redeemed plus any accrued and unpaid interest thereon to the date of such
redemption (the "Redemption Price"), PROVIDED that if at the time there is
available to the Company the opportunity to eliminate, within the 90 Day Period,
the Tax Event by taking some ministerial action ("Ministerial Action"), such as
filing a form or making an election, or pursuing some other similar reasonable
measure which has no adverse effect on the Company, the Trust or the Holders of
the Trust Securities issued by the Trust, the Company shall pursue such
Ministerial Action in lieu of redemption, and, PROVIDED, FURTHER, that the
Company shall have no right to redeem the Debentures while the Trust is pursuing
any Ministerial Action pursuant to its obligations under the Declaration.  The
Redemption Price shall be paid prior to 12:00 noon, New York time, on the date
of such redemption or such earlier time as the Company determines, PROVIDED that
the Company shall deposit with the Trustee an amount sufficient to pay the
Redemption Price by 10:00 a.m., New York time, on the date such Redemption Price
is to be paid.

SECTION 3.2.   OPTIONAL REDEMPTION BY COMPANY.

          (a)  Subject to the provisions of Section 3.2(b) and to the provisions
of Article XI of the Indenture, except as otherwise may be specified in this
First Supplemental Indenture, the Company shall have the right to redeem the
Debentures, in whole or in part, from time to time, on or after July 30, 2001,
at a redemption price equal to 100% of the principal amount to be redeemed plus
any accrued and unpaid interest thereon to the date of such redemption (the
"Optional Redemption Price").  Any redemption pursuant to this paragraph will be
made upon not less than 30 days nor more than 60 days' notice to the Holder of
the Debentures, at the Optional Redemption Price.  If the Debentures are only
partially redeemed pursuant to this Section 3.2, the Debentures will be redeemed
PRO RATA or by lot or by any other method utilized by the Trustee; PROVIDED,
that if at the time of redemption the Debentures are registered as a Global
Debenture, the Depositary shall determine, in accordance with its procedures,
the principal


                                        7
<PAGE>


amount of such Debentures held by each Holder of Debenture to be redeemed.  The
Optional Redemption Price shall be paid prior to 12:00 noon, New York time, on
the date of such redemption or at such earlier time as the Company determines
provided that the Company shall deposit with the Trustee an amount sufficient to
pay the Optional Redemption Price by 10:00 a.m., New York time, on the date such
Optional Redemption Price is to be paid.

          (b)  If a partial redemption of the Debentures would result in the
delisting of the Preferred Securities issued by the Trust from any national
securities exchange or other organization on which the Preferred Securities are
then listed, the Company shall not be permitted to effect such partial
redemption and may only redeem the Debentures in whole.

SECTION 3.3.   NO SINKING FUND.

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


                                   ARTICLE IV
                      EXTENSION OF INTEREST PAYMENT PERIOD

SECTION 4.1.   EXTENSION OF INTEREST PAYMENT PERIOD.

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

SECTION 4.2.   NOTICE OF EXTENSION.


                                        8
<PAGE>


          (a)  If the Institutional Trustee is the only registered Holder of the
Debentures at the time the Company selects an Extended Interest Payment Period,
the Company shall give written notice to the Regular Trustees, the Institutional
Trustee and the Trustee of its selection of such Extended Interest Payment
Period one Business Day before the earlier of (i) the next succeeding date on
which Distributions on the Trust Securities issued by the Trust are payable, or
(ii) the date the Trust is required to give notice of the record date, or the
date such Distributions are payable, to the New York Stock Exchange or other
applicable self-regulatory organization or to holders of the Preferred
Securities issued by the Trust, but in any event at least one Business Day
before such record date.

          (b)  If the Institutional Trustee is not the only Holder of the
Debentures at the time the Company selects an Extended Interest Payment Period,
the Company shall give the Holders of the Debentures and the Trustee written
notice of its selection of such Extended Interest Payment Period 10 Business
Days before the earlier of (i) the next succeeding Interest Payment Date, or
(ii) the date the Company is required to give notice of the record or payment
date of such interest payment to the New York Stock Exchange or other applicable
self-regulatory organization or to Holders of the Debentures.

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

SECTION 4.3.    LIMITATION OF TRANSACTIONS.

          If (i) the Company shall exercise its right to defer payment of
interest as provided in Section 4.1, or (ii) there shall have occurred any Event
of Default, as defined in the Indenture, then (a) the Company shall not declare
or pay any dividend on, make any distributions with respect to, or redeem,
purchase, acquire or make a liquidation payment with respect to, any of its
capital stock or make any guarantee payment with respect thereto (other than
(i) purchases or acquisitions of shares of its common stock in connection with
the satisfaction by the Company of its obligations under any employee benefit
plans or the satisfaction by the Company of its obligations pursuant to any
contract or security requiring the Company to purchase shares of its common
stock, (ii) as a result of a reclassification of its capital stock for another
class or series of its capital stock or (iii) the purchase of fractional
interests in shares of its capital stock pursuant to the conversion or exchange
provisions of such capital stock or security being converted or exchanged) and
(b) the Company shall not make any payment of interest, principal or premium, if
any, on or repay, repurchase or redeem any debt securities issued by the Company
which rank pari passu with or junior to the Debentures.

SECTION 5.1    PAYMENT OF EXPENSES.

          In connection with the offering, sale and issuance of the Debentures

                                  SUBORDINATION

SECTION 6.1.   AGREEMENT TO SUBORDINATE.

          The Company covenants and agrees, and each Holder of Debentures issued
hereunder by such Holder's acceptance thereof likewise covenants and agrees,
that all Debentures shall be issued subject to the provisions of this Article
Six; and each Holder of a Debenture, whether upon original issue or upon
transfer or assignment thereof, accepts and agrees to be bound by such
provisions.

          The payment by the Company of the principal of, premium, if any, and
interest on all Debentures issued hereunder shall, to the extent and in the
manner hereinafter set forth, be subordinated and junior in right of payment to
the prior payment in full of all Senior Indebtedness of the Company, whether
outstanding at the date of this Indenture or thereafter incurred.

          No provision of this Article Six shall prevent the occurrence of any
default or Event of Default hereunder.

SECTION 6.2.   DEFAULT ON SENIOR INDEBTEDNESS.

          In the event and during the continuation of any default by the Company
in the payment of principal, premium, interest or any other payment due on any
Senior Indebtedness of the Company, as the case may be, or in the event that the
maturity of any Senior Indebtedness of the Company, as the case may be, has been
accelerated because of a default, then, in either case, no payment shall be made
by the Company with respect to the principal (including redemption and sinking
fund payments) of, or premium, if any, or interest on the Debentures.

          In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee when such payment is prohibited by the preceding
paragraph of this Section 6.2, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing within 90 days of
such payment of the amounts then due and owing on the Senior Indebtedness and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of Senior Indebtedness.

SECTION 6.3.   LIQUIDATION; DISSOLUTION; BANKRUPTCY.

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

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

          For purposes of this Article Six, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article Six with respect
to the Debentures to the payment of all Senior Indebtedness of the Company, as
the


                                       12
<PAGE>


case may be, that may at the time be outstanding, provided that (i) such Senior
Indebtedness is assumed by the new corporation, if any, resulting from any such
reorganization or readjustment, and (ii) the rights of the holders of such
Senior Indebtedness are not, without the consent of such holders, altered by
such reorganization or readjustment.  The consolidation of the Company with, or
the merger of the Company into, another corporation or the liquidation or
dissolution of the Company following the conveyance or transfer of its property
as an entirety, or substantially as an entirety, to another corporation upon the
terms and conditions provided for in Article VIII of the Indenture shall not be
deemed a dissolution, winding-up, liquidation or reorganization for the purposes
of this Section 6.3 if such other corporation shall, as a part of such
consolidation, merger, conveyance or transfer, comply with the conditions stated
in Article VIII of the Indenture.  Nothing in Section 6.2 or in this Section 6.3
shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 6.7 of the Indenture.

SECTION 6.4.   SUBROGATION.

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

          Nothing contained in this Article Six or elsewhere in the Indenture,
this First Supplemental Indenture or in the Debentures is intended to or shall
impair, as between the Company, its creditors other than the holders of Senior
Indebtedness of the Company, and the Holders of the Debentures, the obligation
of the Company, which is absolute and unconditional, to pay to the Holders of
the Debentures the principal of (and premium, if any) and interest on the
Debentures as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
Holders of the Debentures and creditors of the Company, as the case may be,
other than the holders of Senior Indebtedness of the Company, as the case may
be, nor shall anything herein or therein prevent the Trustee or the Holder of
any Debenture from exercising all remedies otherwise permitted by applicable law
upon default under the Indenture, subject to the rights, if any, under this
Article Six of the holders of such Senior Indebtedness in respect of cash,
property or securities of the Company, as the case may be, received upon the
exercise of any such remedy.


                                       13
<PAGE>


          Upon any payment or distribution of assets of the Company referred to
in this Article Six, the Trustee, subject to the provisions of Section 6.1 of
the Indenture, and the Holders of the Debentures shall be entitled to
conclusively rely upon any order or decree made by any court of competent
jurisdiction in which such dissolution, winding-up, liquidation or
reorganization proceedings are pending, or a certificate of the receiver,
trustee in bankruptcy, liquidation trustee, agent or other Person making such
payment or distribution, delivered to the Trustee or to the Holders of the
Debentures, for the purposes of ascertaining the Persons entitled to participate
in such distribution, the holders of Senior Indebtedness and other indebtedness
of the Company, as the case may be, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article Six.

SECTION 6.5.   TRUSTEE TO EFFECTUATE SUBORDINATION.

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

SECTION 6.6.   NOTICE BY THE COMPANY.

          The Company shall give prompt written notice to a Responsible Officer
of the Trustee of any fact known to the Company that would prohibit the making
of any payment of monies to or by the Trustee in respect of the Debentures
pursuant to the provisions of this Article Six.  Notwithstanding the provisions
of this Article Six or any other provision of the Indenture and this First
Supplemental Indenture, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment of monies
to or by the Trustee in respect of the Debentures pursuant to the provisions of
this Article Six, unless and until a Responsible Officer of the Trustee shall
have received written notice thereof from the Company or a holder or holders of
Senior Indebtedness or from any trustee therefor; and before the receipt of any
such written notice, the Trustee, subject to the provisions of Section 6.1 of
the Indenture, shall be entitled in all respects to assume that no such facts
exist; PROVIDED, HOWEVER, that if the Trustee shall not have received the notice
provided for in this Section 6.6 at least two Business Days prior to the date
upon which by the terms hereof any money may become payable for any purpose
(including, without limitation, the payment of the principal of (or premium, if
any) or interest on any Debenture), then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority to
receive such money and to apply the same to the purposes for which they were
received, and shall not be affected by any notice to the contrary that may be
received by it within two Business Days prior to such date.

          The Trustee, subject to the provisions of Section 6.1 of the
Indenture, shall be entitled to conclusively rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness of the Company, as the case may be (or a trustee on behalf of such
holder), to establish that such notice has been given by a holder of such Senior



                                       14
<PAGE>


Indebtedness or a trustee on behalf of any such holder or holders.  In the event
that the Trustee determines in good faith that further evidence is required with
respect to the right of any Person as a holder of such Senior Indebtedness to
participate in any payment or distribution pursuant to this Article Six, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of such Senior Indebtedness held by
such Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article Six, and, if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

SECTION 6.7.   RIGHTS OF THE TRUSTEE; HOLDERS OF SENIOR INDEBTEDNESS.

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

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

SECTION 6.8.   SUBORDINATION MAY NOT BE IMPAIRED.

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

          Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness of the Company may, at any time and from time
to time, without the consent of or notice to the Trustee or the Holders of the
Debentures, without incurring responsibility to the Holders of the Debentures
and without impairing or releasing the subordination provided in this Article
Six or the obligations hereunder of the Holders of the Debentures to the holders
of such Senior Indebtedness, do any one or more of the following:  (i) change
the


                                       15
<PAGE>


manner, place or terms of payment or extend the time of payment of, or renew or
alter, such Senior Indebtedness, or otherwise amend or supplement in any manner
such Senior Indebtedness or any instrument evidencing the same or any agreement
under which such Senior Indebtedness is outstanding; (ii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing such Senior Indebtedness; (iii) release any Person liable in any manner
for the collection of such Senior Indebtedness; and (iv) exercise or refrain
from exercising any rights against the Company, as the case may be, and any
other Person.

                          COVENANT TO LIST ON EXCHANGE

SECTION 7.1.   LISTING ON AN EXCHANGE.

          If the Debentures are to be issued as a Global Debenture in connection
with the distribution of the Debentures to the holders of the Preferred
Securities issued by the Trust upon a Dissolution Event, the Company will use
its best efforts to list such Debentures on the New York Stock Exchange, Inc. or
on such other exchange as the Preferred Securities are then listed.

                                DUE July 30, 2006

          Sierra Pacific Power Company, a Nevada corporation (the "Company",
which term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to, ______________ or
registered assigns, the principal sum of _____________ Dollars ($___________) on
_________, ____, and to pay interest on said principal sum from July 29, 1996,
or from the most recent interest payment date (each such date, an "Interest
Payment Date") to which interest has been paid or duly provided for, quarterly
(subject to deferral as set forth herein) in arrears on March 31, June 30,
September 30 and December 31 of each year commencing June 30, 1996, at the rate
of 8.60% per annum until the principal hereof shall have become due and payable,
and on any overdue principal and premium, if any, and (without duplication and
to the extent that payment of such interest is enforceable under applicable law)
on any overdue installment of interest at the same rate per annum compounded
quarterly.  The amount of interest payable on any Interest Payment Date shall be
computed on the basis of a 360-day year of twelve 30-day months.  In the event
that any date on which interest is payable on this Debenture is not a Business
Day, then payment of interest payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay), except that, if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date.  The interest installment so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the person in whose name this Debenture (or one or more Predecessor
Securities, as defined in said Indenture) is registered at the close of business
on the regular record date for such interest installment, which shall be the
close of business on the business day next preceding such Interest Payment Date.
 [IF PURSUANT TO THE PROVISIONS OF THE INDENTURE THE DEBENTURES ARE NO LONGER
REPRESENTED BY A GLOBAL DEBENTURE -- which shall be the close of business on the
____ business day next preceding such Interest Payment Date.]  Any such interest
installment not punctually paid or duly provided for shall forthwith cease to be
payable to the registered Holders on such regular record date and may be paid to
the Person in whose name this Debenture (or one or more Predecessor Securities)
is registered at the close of business on a special record date to be fixed by
the Trustee for the payment of such defaulted interest, notice whereof shall be
given to the registered Holders of this series of Debentures not


                                       17

less than 10 days prior to such special record date, or may be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Debentures may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in the
Indenture.  The principal of (and premium, if any) and the interest on this
Debenture shall be payable at the office or agency of the Trustee maintained for
that purpose in any coin or currency of the United States of America that at the
time of payment is legal tender for payment of public and private debts;
PROVIDED, HOWEVER, that payment of interest may be made at the option of the
Company by check mailed to the registered Holder at such address as shall appear
in the Security Register.  Notwithstanding the foregoing, so long as the Holder
of this Debenture is the Institutional Trustee, the payment of the principal of
(and premium, if any) and interest on this Debenture will be made at such place
and to such account as may be designated by the Institutional Trustee.

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

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

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

of such redemption or at such earlier time as the Company determines.  The
Company shall have the right to redeem this Debenture at the option of the
Company, without premium or penalty, in whole or in part at any time on or after
July 30, 2001 (an "Optional Redemption"), or at any time in certain
circumstances upon the occurrence of a Tax Event, at a redemption price equal to
100% of the principal amount plus any accrued but unpaid interest, to the date
of such redemption (the "Optional Redemption Price").  Any redemption pursuant
to this paragraph will be made upon not less than 30 days' nor more than 60
days' notice, at the Optional Redemption Price.  If the Debentures are only
partially redeemed by the Company pursuant to an Optional Redemption, the
Debentures will be redeemed PRO RATA or by lot or by any other method utilized
by the Trustee; provided that if, at the time of redemption, the Debentures are
registered as a Global Debenture, the Depositary shall determine the principal
amount of such Debentures held by each Debentureholder to be redeemed in
accordance with its procedures.

          In the event of redemption of this Debenture in part only, a new
Debenture or Debentures of this series for the unredeemed portion hereof will be
issued in the name of the Holder hereof upon the cancellation hereof.

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

          The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Debentures of each series affected at the time
outstanding, as defined in the Indenture, to execute supplemental indentures for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Indenture or of any supplemental indenture or of
modifying in any manner the rights of the Holders of the Debentures; provided,
however, that no such supplemental indenture shall (i) extend the fixed maturity
of any Debentures of any series, or reduce the principal amount thereof, or
reduce the rate or extend the time of payment of interest thereon, or reduce any
premium payable upon the redemption thereof, without the consent of the Holder
of each Debenture so affected, or (ii) reduce the aforesaid percentage of
Debentures, the Holders of which are required to consent to any such
supplemental indenture, without the consent of the Holders of each Debenture
then outstanding and affected thereby.  The Indenture also contains provisions
permitting the Holders of a majority in aggregate principal amount of the
Debentures of any series at the time outstanding affected thereby, on behalf of
all of the Holders of the Debentures of such series, to waive any past default
in the performance of any of the covenants contained in the Indenture, or
established pursuant to the Indenture with respect to such series, and its
consequences, except a default in the payment of the principal of or premium, if
any, or interest on any of the Debentures of such series.  Any


                                       20
<PAGE>


such consent or waiver by the registered Holder of this Debenture (unless
revoked as provided in the Indenture) shall be conclusive and binding upon such
Holder and upon all future Holders and owners of this Debenture and of any
Debenture issued in exchange herefor or in place hereof (whether by registration
of transfer or otherwise), irrespective of whether or not any notation of such
consent or waiver is made upon this Debenture.

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

          The Company shall have the right at any time during the term of the
Debentures and from time to time to extend the interest payment period of such
Debentures for up to 20 consecutive quarters (an "Extended Interest Payment
Period"), at the end of which period the Company shall pay all interest then
accrued and unpaid (together with interest thereon at the rate specified for the
Debentures to the extent that payment of such interest is enforceable under
applicable law).  Before the termination of any such Extended Interest Payment
Period, the Company may further extend such Extended Interest Payment Period,
provided that such Extended Interest Payment Period together with all such
further extensions thereof shall not exceed 20 consecutive quarters.  At the
termination of any such Extended Interest Payment Period and upon the payment of
all accrued and unpaid interest and any additional amounts then due, the Company
may commence a new Extended Interest Payment Period.

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

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


                                       21
<PAGE>


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

          [The Debentures of this series are issuable only in registered form
without coupons in denominations of $25 and any integral multiple thereof.]
[This Global Debenture is exchangeable for Debentures in definitive form only
under certain limited circumstances set forth in the Indenture.  Debentures of

Indenture and subject to certain limitations [herein and] therein set forth,

principal amount of Debentures of this series of a different authorized
denomination, as requested by the Holder surrendering the same.

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

read into this Preferred Securities Guarantee against the Preferred Guarantee
Trustee.  In case an Event of Default has occurred (that has not been cured or
waived pursuant to Section 2.6) and is actually known to a Responsible Officer
of the Preferred Guarantee Trustee, the Preferred Guarantee Trustee shall
exercise such of the rights and powers vested in it by this Preferred Securities
Guarantee, and use the same degree of care and skill in its exercise thereof, as

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

         Preferred Securities Guarantee, and the Preferred Guarantee Trustee
         shall not be liable except for the performance of such duties and
         obligations as are specifically set forth in this Preferred Securities

         opinions expressed therein, upon any certificates or opinions
         furnished to the Preferred Guarantee Trustee and conforming to the
         requirements of this Preferred Securities Guarantee; but in the case
         of any such certificates or opinions that by any provision hereof are
         specifically required to be furnished to the Preferred Guarantee
         Trustee, the Preferred Guarantee Trustee shall be under a duty to
         examine the same to determine whether or not they conform to the
         requirements of this Preferred Securities Guarantee;

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

         (iii)the Preferred Guarantee Trustee shall not be liable with respect
    to any action taken or omitted to be taken by it in good faith in

    and place of conducting any proceeding for any remedy available to the
    Preferred Guarantee Trustee, or exercising any trust or power conferred
    upon the Preferred Guarantee Trustee under this Preferred Securities
    Guarantee; and

         (iv) no provision of this Preferred Securities Guarantee shall require
    the Preferred Guarantee Trustee to expend or risk its own funds or
    otherwise incur personal financial liability in the performance of any of
    its duties or in the exercise of any of its rights or powers, if the
    Preferred Guarantee Trustee shall have reasonable grounds for believing
    that the repayment of such funds or liability is not reasonably assured to
    it under the terms of this Preferred Securities Guarantee or indemnity,
    reasonably satisfactory to the Preferred Guarantee Trustee, against such
    risk or liability is not reasonably assured to it.

         This GUARANTEE AGREEMENT (the "Common Securities Guarantee"), dated as
of July 29, 1996, is executed and delivered by Sierra Pacific Power Company, a
Nevada corporation (the "Guarantor"), for the benefit of the Holders (as defined
herein) of the Common Securities (as defined herein) of Sierra Pacific Power
Capital I, a Delaware business trust (the "Issuer").

         WHEREAS, pursuant to an Amended and Restated Declaration of Trust (the
"Declaration"), dated as of July 24, 1996, among the Trustees of the Issuer
named therein, the Guarantor, as sponsor, and the holders of undivided
beneficial interests in the assets of the Issuer, the Issuer is issuing on the
date hereof 60,000 common securities, having an aggregate stated liquidation
amount of $1,500,000, designated the 8.60% Trust Originated Common Securities
(the "Common Securities");

         WHEREAS, as incentive for the Holders to purchase the Common
Securities, the Guarantor desires to irrevocably and unconditionally agree, to
the extent set forth in this Common Securities Guarantee, to pay to the Holders
of the Common Securities the Guarantee Payments (as defined herein) and to make
certain other payments on the terms and conditions set forth herein; and

         WHEREAS, the Guarantor is also executing and delivering a guarantee
agreement (the "Preferred Securities Guarantee") in substantially identical
terms to this Common Securities Guarantee for the benefit of the holders of the
Preferred Securities (as defined herein), except that (as set forth herein) if
an Event of Default (as defined in the Indenture), has occurred and is
continuing, the rights of Holders of the Common Securities to receive Guarantee
Payments under this Common Securities Guarantee are subordinated to the rights
of holders of Preferred Securities to receive Guarantee Payments under the
Preferred Securities Guarantee.

         NOW, THEREFORE, in consideration of the purchase by each Holder of
Common Securities, which purchase the Guarantor hereby agrees shall benefit the
Guarantor, the Guarantor executes and delivers this Common Securities Guarantee
for the benefit of the Holders.

There shall be no obligation of the Holders to give notice to, or obtain consent
of, the Guarantor with respect to the happening of any of the foregoing.

amount shall be paid to the Guarantor in violation of the preceding sentence,

over such amount to the Holders.  If an Event of Default (as defined in the

hereunder to make Guarantee Payments pursuant to the terms of this Common
Securities Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 2.3 hereof.
