shall be payable quarterly in arrears on the last day of March, June, 
September and December of each year, commencing on March 31, 1997.  If any 
date on which a Distribution is otherwise payable on the Trust Securities is 
not a Business Day, then the payment of such Distribution shall be made on 
the next succeeding day that is a Business Day (and without any interest or 
other payment in respect of any such delay) except that, if such Business Day 
is in the next succeeding calendar year, payment of such Distribution shall 
be made on the immediately preceding Business Day, in each case with the same 
force and effect as if made on such date (each date on which distributions 
are payable in accordance with this Section 401(a) a "Distribution Date").

    (b)  The Trust Securities represent undivided beneficial interests in the
Trust Property, and, the Distributions on the Trust Securities shall be payable
at a rate of ____% per annum of the Liquidation Amount of the Trust Securities.
The amount of Distributions payable for any full period shall be computed on the
basis of a 360-day year of twelve 30-day months.  The amount of Distributions
for any partial period shall be computed on the basis of the number of days
elapsed in a 360-day year of twelve 30-day months.  The amount of Distributions
payable for any period shall include the Additional Amounts, if any.

                                         -15-



    (c)  Distributions on the Trust Securities shall be made by the Property
Trustee from the Payment Account and shall be payable on each Distribution Date
only to the extent that the Trust has funds then on hand and available in the
Payment Account for the payment of such Distributions.

    (d)  Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register for the Trust Securities on the relevant record date, which shall be
one Business Day prior to such Distribution Date; PROVIDED, HOWEVER, that in the
event that the Preferred Securities do not remain in book-entry-only form, the
relevant record date shall be the date 15 days prior to the relevant
Distribution Date.

    SECTION 402.   REDEMPTION.

    (a)  On each Debenture Redemption Date and on the  stated maturity of the
Debentures, the Trust will be required to redeem a Like Amount of Trust
Securities at the Redemption Price.

    (b)  Notice of redemption shall be given by the Property Trustee by
first-class mail, postage prepaid, mailed not less than 30 nor more than  60
days prior to the Redemption Date to each Holder of Trust Securities to be
redeemed, at such Holder's address appearing in the Security Register.  All
notices of redemption shall state:

          (i)  the Redemption Date;

         (ii)  the Redemption Price;

         (iii) the CUSIP number;

         (iv) if less than all the Outstanding Trust Securities are to be
redeemed, the identification and the total Liquidation Amount of the particular
Trust Securities to be redeemed; and

         (v)  that on the Redemption Date the Redemption Price will become due
and payable upon each such Trust Security to be redeemed and that distributions
thereon will cease to accrue on and after said date.

    (c)  The Trust Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption of Debentures.  Redemptions of the Trust Securities shall be made and
the Redemption Price shall be payable on each Redemption Date only to the extent
that the Trust has funds then on hand and available in the Payment Account for
the payment of such Redemption Price.

    (d)  If the Property Trustee gives a notice of redemption in respect of any
Preferred Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, subject to Section 402(c), the Property Trustee will, so long as the
Preferred Securities are in book-entry-only form, irrevocably deposit with the
Clearing Agency for the Preferred  Securities funds sufficient to pay the
applicable Redemption Price and will give such Clearing Agency irrevocable
instructions and authority to pay the Redemption Price to the holders thereof.
If the Preferred Securities are no longer

                                         -16-



in book-entry-only form, the Property Trustee, subject to Section 402(c), will
irrevocably deposit with the Paying Agent funds sufficient to pay the applicable
Redemption Price and will give the Paying Agent irrevocable instructions and
authority to pay the Redemption Price to the Holders thereof upon surrender of
their Preferred Securities Certificates.  Notwithstanding the foregoing,
Distributions payable on or prior to the Redemption Date for any Trust
Securities called for redemption shall be payable to the Holders of such Trust
Securities as they appear on the Register for the Trust Securities on the
relevant record dates for the related Distribution Dates.  If notice of
redemption shall have been given and funds deposited as  required, then upon the
date of such deposit, all rights of Securityholders holding Trust Securities so
called for redemption will cease, except the  right of such Securityholders to
receive the Redemption Price and any Distribution payable on or prior to the
Redemption Date, but without interest, and such Securities will cease to be
outstanding. In the event that any date on which any Redemption Price is payable
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. In the event that payment of the Redemption Price in
respect of any Trust Securities called for redemption  is improperly withheld or
refused and not paid either by the Trust or by the Depositor pursuant to
the Guarantee, Distributions on such Trust Securities will continue to accrue,
at the then applicable rate, from the Redemption Date originally established by
the Trust for such Trust Securities to the date such Redemption Price is
actually paid, in which  case the actual payment date will be the date fixed for
redemption for purposes of calculating the Redemption Price.

    (e)  Payment of the Redemption Price on the Trust Securities shall be made
to the recordholders thereof as they appear on the Securities Register for the
Trust Securities on the relevant record date, which shall be one Business Day
prior to the relevant Redemption Date; PROVIDED, HOWEVER, that in the event that
the Preferred Securities do not remain in book-entry-only form, the relevant
record date shall be the date fifteen days prior to the relevant Redemption
Date.

    (f)  Subject to Section 403(a), if less than all the Outstanding Trust
Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated on a
pro rata basis (based on Liquidation Amounts) among the Common Securities and
the Preferred Securities.  The particular Preferred Securities to be redeemed
shall be selected on a pro rata basis (based upon Liquidation Amounts) not more
than 60 days prior to the Redemption Date by the Property Trustee from the
Outstanding Preferred Securities not previously called for redemption, by such
method (including, without limitation, by lot) as the Property Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
of portions (equal to $25 or an integral multiple of $25 in excess thereof) of
the Liquidation Amount of Preferred Securities of a denomination larger than
$25.  The Property Trustee shall promptly notify the Security Registrar in
writing of the Preferred Securities selected for redemption and, in the case of
any Preferred Securities selected for partial redemption, the Liquidation Amount
thereof to be redeemed.  For all purposes of this Trust Agreement, unless the
context otherwise requires, all provisions relating to the redemption of
Preferred Securities shall relate, in the case of any Preferred Securities
redeemed or to be redeemed only in part, to the  portion of the Liquidation
Amount of Preferred Securities that has been or is to be redeemed.

                                         -17-



    SECTION 403.   SUBORDINATION OF COMMON SECURITIES.

    (a)  Payment of Distributions (including Additional Amounts, if applicable)
on, and the Redemption Price of, the Trust Securities, as applicable, shall be
made, subject to Section 402(f), pro rata among the Common Securities and the
Preferred Securities based on the Liquidation Amount of the Trust Securities;
provided, however, that if on any Distribution Date or Redemption Date any Event
of Default resulting from a Debenture Event of Default shall have occurred and
be continuing, no payment of any Distribution (including Additional Amounts, if
applicable) on, or Redemption Price of, any Common Security, and no other
payment on account of the redemption, liquidation or other acquisition of Common
Securities, shall be made unless payment in full in cash of all accumulated and
unpaid Distributions (including Additional Amounts, if applicable) on all
Outstanding Preferred Securities for all Distribution periods terminating on or
prior thereto, or in the case of payment of the Redemption Price the full amount
of such Redemption Price on all Outstanding Preferred Securities, shall have
been made or provided for, and all funds immediately available to the Property
Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or the
Redemption Price of, Preferred Securities then due and payable.

    (b)  In the case of the occurrence of any Event of Default resulting from a
Debenture Event of Default, the Holder of Common Securities will be deemed to
have waived any right to act with respect to any such Event of Default under
this Trust Agreement until the effect of all such Events of Default with respect
to the Preferred Securities have been cured, waived or otherwise eliminated.
Until any such Event of Default under this Trust Agreement with respect to the
Preferred Securities has been so cured, waived or otherwise eliminated, the
Property Trustee shall act solely on behalf of the Holders of the Preferred
Securities and not the Holder of the Common Securities, and only the Holders of
the Preferred Securities will have the right to direct the Property Trustee to
act on their behalf.

    SECTION 404.   PAYMENT PROCEDURES.  Payments of Distributions (including
Additional Amounts, if applicable) in respect of the Preferred Securities shall
be made by check mailed to the address of the Person entitled thereto as such
address shall appear on the Securities Register or, if the Preferred
Securities are held by a Clearing Agency, such Distributions shall be made to
the Clearing Agency in immediately available funds, which shall credit the
relevant Persons' accounts at such Clearing Agency on the applicable
distribution dates.  Payments in respect of the Common Securities shall be
made in such manner as shall be mutually agreed between the Property Trustee and
the Common Securityholder.

    SECTION 405.   TAX RETURNS AND REPORTS.  The Administrative Trustees shall
prepare (or cause to be prepared), at the Depositor's expense, and file all
United States federal, state and local tax and information returns and reports
required to be filed by or in respect of the Trust.  In this regard, the
Administrative Trustees shall (a) prepare and file (or cause to be prepared
and filed) the appropriate Internal Revenue Service Form required to be filed in
respect of the Trust in each taxable year of the Trust and (b) prepare and
furnish (or cause to be prepared and furnished) to each Securityholder the
appropriate Internal Revenue Service form required to be furnished to such
Securityholder or the information required to be provided on such form.  The
Administrative Trustees shall provide the Depositor and the Property Trustee
with a copy of all such returns and reports

                                         -18-



promptly after such filing or furnishing.  The Trustees shall comply with United
States federal withholding and backup withholding tax laws and information
reporting requirements with respect to any payments to Securityholders under the
Trust Securities.

    Section 406.   PAYMENT OF TAXES, DUTIES, ETC. OF THE TRUST.  Upon receipt
under the Debentures of Additional Sums, the Property Trustee shall promptly pay
any taxes, duties or governmental charges of whatsoever nature (other than
withholding taxes) imposed on the Trust by the United States or any other taxing
authority.

    Section 407.   PAYMENTS UNDER INDENTURE.  Any amount payable hereunder to
any Holder of Preferred Securities (and any Owner with respect thereto) shall be
reduced by the amount of any corresponding payment such Holder (and Owner) has
directly received pursuant to Section 508 of the Indenture.

                                      ARTICLE V

                            TRUST SECURITIES CERTIFICATES

    Section 501.   INITIAL OWNERSHIP.  Upon the formation of the Trust and the
contribution by the Depositor pursuant to Section 203 and until the issuance
of the Trust Securities, and at any time during which no Trust Securities are
outstanding, the Depositor shall be the sole beneficial owner of the Trust.

    Section 502.   THE TRUST SECURITIES CERTIFICATES.  The Preferred Securities
Certificates shall be issued in minimum denominations of $25 Liquidation Amount
and integral multiples of $25 in excess thereof, and the Common Securities
Certificates shall be issued in denominations of $25 Liquidation Amount and
integral multiples thereof.  The Trust Securities Certificates shall be executed
on behalf of the Trust by manual signature of at least one Administrative
Trustee.  Trust Securities Certificates bearing the manual signatures of
individuals who were, at the time when such signatures shall have been affixed,
authorized to sign on behalf of the Trust, shall be validly issued and
entitled to the benefits of this Trust Agreement, notwithstanding that such
individuals or any of them shall have ceased to be so authorized prior to the
delivery of such Trust Securities Certificates or did not hold such offices at
the date of delivery of such Trust Securities Certificates.  A transferee of a
Trust Securities Certificate shall become a Securityholder, and shall be
entitled to the rights and subject to the obligations of a Securityholder
hereunder, upon due registration of such Trust Securities Certificate in such
transferee's name pursuant to Sections 504, 511 and 513.

    Section 503.   EXECUTION AND DELIVERY OF TRUST SECURITIES CERTIFICATES.  At
each Time of Delivery, the Administrative Trustees shall cause Trust Securities
Certificates, in an aggregate Liquidation Amount as provided in Sections 204 and
205, to be executed on behalf of the Trust and delivered to or upon the written
order of the Depositor, signed by its chairman of the board, its president, any
executive vice president, senior vice president or any vice president, treasurer
or assistant treasurer or controller without further corporate action by the
Depositor, in authorized denominations.

                                         -19-



    Section 504.   REGISTRATION OF TRANSFER AND EXCHANGE OF PREFERRED
SECURITIES CERTIFICATES.  The Depositor shall keep or cause to be kept, at the
office or Agency maintained pursuant to Section 508, a register or registers for
the purpose of registering Trust Securities Certificates and transfers and
exchanges of Preferred Securities Certificates (the "Securities Register") in
which, the registrar designated by the Depositor (the "Securities Registrar"),
subject to such reasonable regulations as it may prescribe, shall provide for
the registration of Preferred Securities Certificates and Common Securities
Certificates (subject to Section 510 in the case of the Common Securities
Certificates) and registration of transfers and exchanges of Preferred
Securities Certificates as herein provided.  The Bank shall be the initial
Securities Registrar.

    Upon surrender for registration of transfer of any Preferred Securities
Certificate at the office or Agency maintained pursuant to Section 508, the
Administrative Trustees or any one of them shall execute and deliver, in the
name of the designated transferee or transferees, one or more new Preferred
Securities Certificates in authorized denominations of a like aggregate
Liquidation Amount dated the date of execution by such Administrative Trustee
or Trustees.  The Securities Registrar shall not be required to register the
transfer of any Preferred Securities that have been called for redemption.  At
the option of a Holder, Preferred Securities Certificates may be exchanged for
other Preferred Securities Certificates in authorized denominations of the same
class and of a like aggregate Liquidation Amount upon surrender of the Preferred
Securities Certificates to be exchanged at the office or Agency maintained
pursuant to Section 508.

    Every Preferred Securities Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Property Trustee and the
Securities Registrar duly executed by the Holder or his attorney duly authorized
in writing.  Each Preferred Securities Certificate surrendered for
registration of transfer or exchange shall be cancelled and subsequently
disposed of by the Property Trustee in accordance with its customary practice.

    No service charge shall be made for any registration of transfer or
exchange of Preferred Securities Certificates, but the Securities Registrar may
require payment of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer or exchange of Preferred
Securities Certificates.

    Section 505.   MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES
CERTIFICATES.  If (a) any mutilated Trust Securities Certificate shall be
surrendered to the Securities Registrar, or if the Securities Registrar shall
receive evidence to its satisfaction of the destruction, loss or theft of any
Trust Securities Certificate and (b) there shall be delivered to the Securities
Registrar and the Administrative Trustees such security or indemnity as may be
required by them to save each of them harmless, then in the absence of notice
that such Trust Securities Certificate shall have been acquired by a bona fide
purchaser, the Administrative Trustees, or any one of them, on behalf of the
Trust shall execute and make available for delivery, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Trust Securities Certificate, a
new Trust Securities Certificate of like class, tenor and denomination.  In
connection with the issuance of any new Trust Securities Certificate under this
Section, the Administrative Trustees or the Securities Registrar may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection

                                         -20-



therewith.  Any duplicate Trust Securities Certificate issued pursuant to this
Section shall constitute conclusive evidence of an undivided beneficial interest
in the assets of the Trust, as if originally issued, whether or not the lost,
stolen or destroyed Trust Securities Certificate shall be found at any time.

    SECTION 506.   PERSONS DEEMED SECURITYHOLDERS.  The Administrative Trustees
or the Securities Registrar shall treat the Person in whose name any Trust
Securities Certificate shall be registered in the Securities Register as the
owner of such Trust Securities Certificate for the purpose of receiving
distributions and for all other purposes whatsoever, and neither the Trustees
nor the Securities Registrar shall be bound by any notice to the contrary.

    SECTION 507.   ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND ADDRESSES.  The
Administrative Trustees or the Depositor shall furnish or cause to be furnished
(a) to the Property Trustee, semi-annually on or before January 15 and July 15
in each year, a list, in such form as the Property Trustee may reasonably
require, of the names and addresses of the   Securityholders as of the most
recent Record Date and (b) to the Property Trustee, promptly after receipt by
any Administrative Trustee or the Depositor of a request therefor from the
Property Trustee in order to enable the Property Trustee to discharge its
obligations under this Trust Agreement, in each case to the extent such
information is in the possession or control of the Administrative Trustees or
the Depositor and is not identical to a previously supplied list or has not
otherwise been received by the Property Trustee in its capacity as Securities
Registrar.  The rights of Securityholders to communicate with other
Securityholders with respect to their rights under this Trust Agreement or under
the Trust Securities, and the corresponding rights of the Trustee shall be as
provided in the Trust Indenture Act.  Each Holder, by receiving and holding a
Trust Securities Certificate, and each Owner shall be deemed to have agreed not
to hold the Depositor, the Property Trustee or the Administrative Trustees
accountable by reason of the disclosure of its name and address, regardless of
the source from which such information was derived.

    SECTION 508.   MAINTENANCE OF OFFICE OR AGENCY.  The Administrative
Trustees shall maintain an office or offices or Agency or agencies where
Preferred Securities Certificates may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Trustees in
respect of the Trust Securities Certificates may be served.  The Administrative
Trustees initially designate Nevada Power Company, 6226 West Sahara Avenue, Las
Vegas, Nevada 89102, Attention:  Treasurer, as the office for such purposes. The
Administrative Trustees shall give prompt written notice to the Depositor and to
the Securityholders of any change in the location of the Securities Register or
any such office or Agency.

    SECTION 509.   APPOINTMENT OF PAYING AGENT.  The Paying Agent shall make
distributions to Securityholders from the Payment Account and shall report the
amounts of such distributions to the Property Trustee and the Administrative
Trustees.  Any Paying Agent shall have the revocable power to withdraw funds
from the Payment Account for the purpose of making the distributions referred to
above.  The Administrative Trustees may revoke such power and remove the Paying
Agent if such Trustees determine in their sole discretion that the Paying Agent
shall have failed to perform its obligations under this Trust Agreement in any
material respect.  The Paying Agent shall initially be the Bank, and any
co-paying agent chosen by the Bank and acceptable to the Administrative Trustees
and the Depositor.  Any Person acting as Paying Agent shall be permitted

                                         -21-



to resign as Paying Agent upon 30 days' written notice to the Administrative
Trustees, the Property Trustee and the Depositor.  In the event that the Bank
shall no longer be the Paying Agent or a successor Paying Agent shall resign or
its authority to act be revoked, the Administrative Trustees shall appoint a
successor that is acceptable to the Property Trustee and the Depositor to act as
Paying Agent (which shall be a bank or trust company).  The Administrative
Trustees shall cause such successor Paying Agent or any additional Paying Agent
appointed by the Administrative Trustees to execute and deliver to the Trustees
an instrument in which such successor Paying Agent or additional Paying Agent
shall agree with the Trustees that as Paying Agent, such successor Paying Agent
or additional Paying Agent will hold all sums, if any, held by it for payment to
the Securityholders in trust for the benefit of the Securityholders entitled
thereto until such sums shall be paid to such Securityholders. The Paying Agent
shall return all unclaimed funds to the Property Trustee and upon removal of a
Paying Agent such Paying Agent shall also return all funds in its possession to
the Property Trustee.  The provisions of Sections 801, 803 and 806 shall apply
to the Bank also in its role as Paying Agent, for so long as the Bank shall act
as Paying Agent and, to the extent applicable, to any other paying agent
appointed hereunder.  Any reference in this Agreement to the Paying Agent shall
include any co-paying agent unless the context requires otherwise.

    SECTION 510.   OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.  At each Time
of Delivery, the Depositor shall acquire and retain beneficial and record
ownership of the Common Securities.  To the fullest extent permitted by law,
other than a transfer in connection with a consolidation or merger of the
Depositor into another corporation, or any conveyance, transfer or lease by the
Depositor of its properties and assets substantially as an entirety to any
Person, pursuant to Section 801 of the Indenture, any attempted transfer of the
Common Securities shall be void.  The Administrative Trustees shall cause each
Common Securities Certificate issued to the Depositor to contain a legend
stating "THIS CERTIFICATE IS NOT TRANSFERABLE".

    SECTION 511.   BOOK-ENTRY PREFERRED SECURITIES CERTIFICATES; COMMON
SECURITIES  CERTIFICATE.  (a)  The Preferred Securities Certificates, upon
original issuance, will be issued in the form of a typewritten Preferred
Securities Certificate or Certificates representing Book-Entry Preferred
Securities Certificates, to be delivered to The Depository Trust Company, the
initial Clearing Agency, by, or on behalf of, the Trust.  Such Preferred
Securities Certificate or Certificates shall initially be registered on the
Securities Register in the name of Cede & Co., the nominee of the initial
Clearing Agency, and no beneficial owner will receive a Definitive Preferred
Securities Certificate representing such beneficial owner's interest in such
Preferred Securities, except as provided in Section 513.  Unless and until
Definitive Preferred Securities Certificates have been issued to beneficial
owners pursuant to Section 513:

         (i)  the provisions of this Section 511(a) shall be in full force and
    effect;

         (ii) the Securities Registrar and the Trustees shall be entitled to
    deal with the Clearing Agency for all purposes of this Trust Agreement
    relating to the Book-Entry Preferred Securities Certificates (including the
    payment of the Liquidation Amount of and Distributions on the Book-Entry
    Preferred Securities and the giving of instructions or directions to Owners
    of Book-Entry Preferred Securities) as the sole Holder of Book-Entry
    Preferred Securities and shall have no obligations to the Owners thereof;

                                         -22-



         (iii)     to the extent that the provisions of this Section 511
    conflict with any other provisions of this Trust Agreement, the provisions
    of this Section 511 shall control; and

         (iv) the rights of the Owners of the Book-Entry Preferred Securities
    Certificates shall be exercised only through the Clearing Agency and shall
    be limited to those established by law and agreements between such Owners
    and the Clearing Agency and/or the Clearing Agency Participants.  Pursuant
    to the Certificate Depository Agreement, unless and until Definitive
    Preferred Securities Certificates are issued pursuant to Section 513, the
    initial Clearing Agency will make book-entry transfers among the Clearing
    Agency Participants and receive and transmit payments on the Preferred
    Securities to such Clearing Agency Participants.

    (b)  A single Common Securities Certificate representing the Common
Securities shall be issued to the Depositor in the form of a definitive Common
Securities Certificate.

    SECTION 512.   NOTICES TO CLEARING AGENCY.  To the extent that a notice or
other communication to the Owners is required under this Trust Agreement, unless
and until Definitive Preferred Securities Certificates shall have been issued to
Owners pursuant to Section 513, the Trustees shall give all such notices and
communications specified herein to be given to Owners to the Clearing Agency,
and shall have no   obligations to the Owners.

    SECTION 513.   DEFINITIVE PREFERRED SECURITIES CERTIFICATES.  If (a) the
Depositor advises the Trustees in writing that the Clearing Agency is no longer
willing or able to properly discharge its responsibilities with respect to the
Preferred Securities Certificates, and the Depositor is unable to locate a
qualified successor, (b) the Depositor at its option advises the Trustees in
writing that it elects to terminate the book-entry system through the Clearing
Agency, or (c) after the occurrence of a Debenture Event of Default, Owners of
Preferred Securities Certificates representing beneficial interests aggregating
at least a majority of the Liquidation Amount advise the Property Trustee in
writing that the continuation of a book-entry system through the Clearing Agency
is no longer in the best interest of the Owners of Preferred Securities
Certificates, then the Property Trustee shall notify the Clearing Agency and the
Clearing Agency shall notify all Owners of Preferred Securities Certificates and
the other Trustees of the occurrence of any such event and of the availability
of the Definitive Preferred Securities Certificates to Owners of such class or
classes, as applicable, requesting the same.  Upon surrender to the Property
Trustee of the typewritten Preferred Securities Certificate or Certificates
representing the Book-Entry Preferred Securities Certificates by the Clearing
Agency, accompanied by registration instructions, the Administrative Trustees,
or any one of them, shall execute the Definitive Preferred Securities
Certificates in accordance with the instructions of the Clearing Agency.
Neither the Securities Registrar nor the Trustees shall be liable for any delay
in delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. Upon the issuance of Definitive
Preferred Securities Certificates, the Trustees shall recognize the Holders of
the Definitive Preferred Securities Certificates as Securityholders.  The
Definitive Preferred Securities Certificates shall be printed, lithographed or
engraved or may be produced in any other manner as is reasonably acceptable to
the Administrative Trustees, as evidenced by the execution thereof by the
Administrative Trustees or any one of them.

                                         -23-



    SECTION 514.   RIGHTS OF SECURITYHOLDERS.

    (a)  The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 209, and
the Securityholders shall not have any right or title therein other than the
undivided beneficial interest in the assets of the Trust conferred by their
Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights
specifically set forth therein and in this Trust Agreement.  The Trust
Securities shall have no preemptive or similar rights and when issued and
delivered to Securityholders against payment of the purchase price therefor will
be fully paid and nonassessable by the Trust.  The Holders of the Trust
Securities, in their capacities as such, 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.

    (b)  For so long as any Preferred Securities remain Outstanding, if, upon a
Debenture Event of Default, the Debenture Trustee fails or the holders of not
less than 25% in principal amount of the outstanding Debentures fail to declare
the principal of all of the Debentures to be immediately due and payable, the
Holders of at least 25% in Liquidation Amount of the Preferred Securities then
Outstanding shall have such right by a notice in writing to the Depositor and
the Debenture Trustee;  and upon any such declaration such principal amount of
and the accrued interest on all of the Debentures shall become immediately due
and payable, provided that the payment of principal and interest on such
Debentures shall remain subordinated to the extent provided in the Indenture.

    (c)  For so long as any Preferred Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Trust
Agreement, if, upon a Debenture Event of Default specified in Section 501(1) or
501(2) of the Indenture, any Holder of Preferred Securities shall have the right
to directly institute a proceeding for enforcement of payment to such Holder of
the principal amount of or interest on the Debentures having a principal amount
equal to the Liquidation Amount of the Preferred Securities of such Holder (a
"Direct Action").  In connection with such Direct Action,  the rights of the
Holders of the Common Securities will be subrogated to the rights of any Holder
of the Preferred Securities to the extent of any payment made by the Depositor
to such Holder of Preferred Securities in such Direct Action.  Except as set
forth in this Section 514(c), the Holders of Preferred Securities will not be
able to exercise directly any other remedy available to the holders of the
Debentures or assert directly any other rights in respect of the Debentures.


                                      ARTICLE VI

                      ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

    SECTION 601.   LIMITATIONS ON VOTING RIGHTS.

    (a)  Except as provided in this Section, in Sections 810 and 1002 and in
the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any

                                         -24-



manner otherwise control the administration, operation and management of the
Trust or the obligations of the parties hereto, nor shall anything herein set
forth, or contained in the terms of the Trust Securities Certificates, be
construed so as to constitute the Securityholders from time to time as partners
or members of an association.

    (b)  So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on the Debenture Trustee with respect to such
Debentures, (ii) waive any past default which is waiveable under Section 513 of
the Indenture, (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable or (iv) consent to
any amendment, modification or termination of the Indenture or the
Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of at least a majority in
Liquidation Amount of all Outstanding Preferred Securities; provided, however,
that where a consent under the Indenture would require the consent of each
Holder of Debentures affected thereby, no such consent shall be given by the
Property Trustee without the prior written consent of each Holder of Preferred
Securities.  The Trustees shall not revoke any action previously authorized or
approved by a vote of the Holders of Preferred Securities, except by a
subsequent vote of the Holders of Preferred Securities.  The Property Trustee
shall notify all Holders of the Preferred Securities of any notice of default
received from the Debenture Trustee with respect to the Debentures.  In addition
to obtaining the foregoing approvals of the Holders of the  Preferred
Securities, prior to taking any of the foregoing actions, the Trustees shall, at
the expense of the Depositor, obtain an Opinion of Counsel experienced in such
matters to the effect that the Trust will not be classified as an association
taxable as a corporation for United States federal income tax purposes on
account of such action.

    (c)  If any proposed amendment to the Trust Agreement provides for, or the
Trustees otherwise propose to effect, (i) any action that would adversely affect
in any material respect the powers, preferences or special rights of the
Preferred Securities, whether by way of amendment to the Trust Agreement or
otherwise, or (ii) the dissolution, winding-up or termination of the Trust,
other than pursuant to the terms of this Trust Agreement, then the Holders of
Outstanding Preferred Securities as a 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 the Holders of at least a majority in Liquidation
Amount of the Outstanding Preferred Securities.  No amendment to this Trust
Agreement may be made if, as a result of such amendment, the Trust would be
classified as an association taxable as a corporation for United States federal
income tax purposes.

    SECTION 602.   NOTICE OF MEETINGS.  Notice of all meetings of the Preferred
Securityholders, stating the time, place and purpose of the meeting, shall be
given by the Property Trustee pursuant to Section 1008 to each Preferred
Securityholder of record, at his registered address, at least 15 days and not
more than 90 days before the meeting.  At any such meeting, any business
properly before the meeting may be so considered whether or not stated in the
notice of the meeting.  Any adjourned meeting may be held as adjourned without
further notice.

    SECTION 603.   MEETINGS OF PREFERRED SECURITYHOLDERS.  No annual meeting of
Securityholders is required to be held.  The Administrative Trustees, however,
shall call a meeting

                                         -25-



of Securityholders to vote on any matter upon the written request of the
Preferred Securityholders of record of 25% of the Preferred Securities (based
upon their Liquidation Amount) and the Administrative Trustees or the Property
Trustee may, at any time in their discretion, call a meeting of Preferred
Securityholders to vote on any matters as to which Preferred Securityholders are
entitled to vote.

    Preferred Securityholders of record of 50% of the Outstanding Preferred
Securities (based upon their Liquidation Amount), present in person or by proxy,
shall constitute a quorum at any meeting of Securityholders.

    If a quorum is present at a meeting, an affirmative vote by the Preferred
Securityholders of record present, in person or by proxy, holding more than a
majority of the Preferred Securities (based upon their Liquidation Amount) held
by the Preferred Securityholders of record present, either in person or by
proxy, at such meeting shall constitute the action of the Securityholders,
unless this Trust Agreement requires a greater number of affirmative votes.

    SECTION 604.   VOTING RIGHTS.  Securityholders shall be entitled to one
vote for each $25 of Liquidation Amount represented by their Trust Securities in
respect of any matter as to which such Securityholders are entitled to vote.

    SECTION 605.   PROXIES, ETC.  At any meeting of Securityholders, any
Securityholder entitled to vote thereat may vote by proxy, provided that no
proxy shall be voted at any meeting unless it shall have been placed on file
with the Administrative Trustees, or with such other officer or agent of the
Trust as the Administrative Trustees may direct, for verification prior to the
time at   which such vote shall be taken.  Pursuant to a resolution of the
Property Trustee, proxies may be solicited in the name of the Property Trustee
or one or more officers of the Property Trustee.  Only Securityholders of record
shall be entitled to vote.  When Trust Securities are held jointly by several
persons, any one of them may vote at any meeting in person or by proxy in
respect of such Trust Securities, but if more than one of them shall be present
at such meeting in person or by proxy, and such joint owners or their   proxies
so present disagree as to any vote to be cast, such vote shall not be   received
in respect of such Trust Securities.  A proxy purporting to be executed by or on
behalf of a Securityholder shall be deemed valid unless challenged at or prior
to its exercise, and the burden of proving invalidity shall rest on the
challenger.  No proxy shall be valid more than three years after its date of
execution.

    SECTION 606.   SECURITYHOLDER ACTION BY WRITTEN CONSENT.  Any action which
may be taken by Securityholders at a meeting may be taken without a meeting if
Securityholders holding more than a majority of all Outstanding Trust Securities
(based upon their Liquidation Amount) entitled to vote in respect of such action
(or such larger proportion thereof as shall be required by any express provision
of this Trust Agreement) shall consent to the action in writing.

    SECTION 607.   RECORD DATE FOR VOTING AND OTHER PURPOSES.  For the purposes
of determining the Securityholders who are entitled to notice of and to vote at
any meeting or by written consent, or to participate in any distribution on the
Trust Securities in respect of which a record date is not otherwise provided for
in this Trust Agreement, or for the purpose of any other action, the

                                         -26-



Administrative Trustees may from time to time fix a date, not more than 90 days
prior to the date of any meeting of Securityholders or the payment of a
distribution or other action, as the case may be, as a record date for the
determination of the identity of the Securityholders of record for such
purposes.

    SECTION 608.   ACTS OF SECURITYHOLDERS.  Any request, demand,
authorization, direction, notice, consent, waiver or other action provided or
permitted by this Trust Agreement to be given, made or taken by Securityholders
or Owners may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Securityholders or Owners in person
or by an agent duly appointed in writing; and, except as otherwise expressly
provided herein, such action shall   become effective when such instrument or
instruments are delivered to an Administrative Trustee.  Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Securityholders or Owners signing such
instrument or instruments.  Proof of execution of any such instrument or of a
writing appointing any such agent shall be sufficient for any purpose of this
Trust Agreement and (subject to Section 801) conclusive in favor of the
Trustees, if made in the manner provided in this Section.

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

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

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

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

    If any dispute shall arise between the Securityholders and the
Administrative Trustees or among such Securityholders or Trustees with respect
to the authenticity, validity or binding nature of any request, demand,
authorization, direction, consent, waiver or other Act of such Securityholder or
Trustee under this Article VI, then the determination of such matter by the
Property Trustee shall be conclusive with respect to such matter.

                                         -27-



    A Securityholder may institute a legal proceeding directly against the
Depositor under the Guarantee to enforce its rights under the Guarantee without
first instituting a legal proceeding against the Guarantee Trustee (as defined
in the Guarantee), the Trust or any person or entity.

    SECTION 609.   INSPECTION OF RECORDS.  Upon reasonable notice to the
Administrative Trustees and the Property Trustee, the records of the Trust shall
be open to inspection by Securityholders during normal business hours for any
purpose reasonably related to such Securityholder's interest as a
Securityholder.

                                     ARTICLE VIII

                                     THE TRUSTEES

    SECTION 801.   CERTAIN DUTIES AND RESPONSIBILITIES.  (a)  The duties and
responsibilities of the Trustees shall be as provided by this Trust Agreement
and, in the case of the Property Trustee, by the Trust Indenture Act.
Notwithstanding the foregoing, no provision of this Trust Agreement shall
require the Trustees to expend or risk their own funds or otherwise incur any
financial liability in the performance of any of their duties hereunder, or in
the exercise of any of their rights or powers,

                                         -29-



if they shall have reasonable grounds for believing that repayment of such 
funds or adequate indemnity against such risk or liability is not reasonably 
assured to it. Whether or not therein expressly so provided, every provision 
of this Trust Agreement relating to the conduct or affecting the liability of 
or affording protection to the Trustees shall be subject to the provisions of 
this Section. Nothing in this Trust    Agreement shall be construed to 
release the Property Trustee from liability for its own negligent action, its 
own negligent failure to act, or its own willful misconduct. To the extent 
that, at law or in equity, an Administrative Trustee has duties (including 
fiduciary duties) and liabilities relating thereto to the Trust or to the 
Securityholders, such Administrative Trustee shall not be liable to the Trust 
or to any Securityholder for such Trustee's good faith reliance on the 
provisions of this Trust Agreement.  The provisions of this Trust Agreement, 
to the extent that they restrict the duties and liabilities of the 
Administrative Trustees otherwise existing at law or in equity, are agreed by 
the Depositor and the Securityholders to replace such other duties and 
liabilities of the Administrative Trustees.

    (b)  All payments made by the Property Trustee or a Paying Agent in respect
of the Trust Securities shall be made only from the revenue and proceeds from
the Trust Property and only to the extent that there shall be sufficient revenue
or proceeds from the Trust Property to enable the Property Trustee or a Paying
Agent to make payments in accordance with the terms hereof.  Each
Securityholder, by its acceptance of a Trust Security, agrees that it will look
solely to the revenue and proceeds from the Trust Property to the extent legally
available for distribution to it as herein provided and that the Trustees are
not personally liable to it for any amount  distributable in respect of any
Trust Security or for any other liability in respect of any Trust Security.
This Section 801(b) does not limit the liability of the Trustees expressly set
forth elsewhere in this Trust Agreement or, in the case of the Property Trustee,
in the Trust Indenture Act.

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

         (i)   the Property Trustee shall not be liable for any error of
    judgment made in good faith by an authorized officer of the Property 
    Trustee, unless it shall be proved that the Property Trustee was 
    negligent in ascertaining the pertinent facts;

         (ii)  the Property 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 Trust Securities relating to the time, method 
    and place of conducting any proceeding for any remedy available to the 
    Property Trustee, or exercising any trust or power conferred upon the 
    Property Trustee under this Trust Agreement;

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

                                         -30-



         (iv)  the Property Trustee shall not be liable for any interest on any
    money received by it except as it may otherwise agree with the Depositor, 
    and money held by the Property Trustee need not be segregated from other 
    funds held by it except in relation to the Payment Account maintained by 
    the Property Trustee pursuant to Section 301 and except to the extent 
    otherwise required by law; and

         (v)   the Property Trustee shall not be responsible for monitoring the
    compliance by the Administrative Trustees or the Depositor with their 
    respective duties under this Trust Agreement, nor shall the Property 
    Trustee be liable for the default or misconduct of the Administrative 
    Trustees or the Depositor.

    SECTION 802.   CERTAIN NOTICES.  Within five Business Days after the 
occurrence of any Event of Default actually known to the Property Trustee, 
the Property Trustee shall transmit, in the manner and to the extent provided 
in Section 1008, notice of such Event of Default to the Securityholders, the 
Administrative Trustees and the Depositor, unless such Event of Default shall 
have been cured or waived.

    Within five Business Days after the receipt of notice of the Depositor's
exercise of its right to defer the payment of interest on the   Debentures
pursuant to the Indenture, the Administrative Trustee shall transmit, in the
manner and to the extent provided in Section 1008, notice of such exercise to
the Securityholders and the Property Trustee, unless such exercise shall have
been revoked.

    SECTION 803.   CERTAIN RIGHTS OF PROPERTY TRUSTEE.  Subject to the
provisions of Section 801:

         (a)  the Property Trustee may rely and shall be protected in acting or
    refraining from acting in good faith upon any resolution, Opinion of
    Counsel, certificate, written representation of a Holder or transferee,
    certificate of auditors or any other certificate, statement, instrument,
    opinion, report, notice, request, consent, order, appraisal, bond,
    debenture, note, other evidence of indebtedness or other paper or document
    believed by it to be genuine and to have been signed or presented by the
    proper party or parties;

         (b)  if (i) in performing its duties under this Trust Agreement the
    Property Trustee is required to decide between alternative courses of
    action or (ii) in construing any of the provisions of this Trust Agreement
    the Property Trustee finds the same ambiguous or inconsistent with any
    other provisions contained herein or (iii) the Property Trustee is unsure
    of the application of any provision of this Trust Agreement, then, except
    as to any matter as to which the Preferred Securityholders are entitled to
    vote under the terms of this Trust Agreement, the Property Trustee shall
    deliver a notice to the Depositor requesting written instructions of the
    Depositor as to the course of action to be  taken and the Property Trustee
    shall take such action, or refrain from taking such action, as the Property
    Trustee shall be instructed in writing to take, or to refrain from taking,
    by the Depositor; provided, however, that if the Property Trustee does not
    receive such instructions of the Depositor within ten Business Days after
    it has delivered such notice, or such reasonably shorter period of time set

                                         -31-



    forth in such notice (which to the extent practicable shall not be less
    than two Business Days), it may, but shall be under no duty to, take or
    refrain from taking such action not inconsistent with this Trust Agreement
    as it shall deem advisable and in the best interests of the
    Securityholders, in which event the Property Trustee shall have no
    liability except for its own bad faith, negligence or willful misconduct;

         (c)  any direction or act of the Depositor or the Administrative
    Trustees contemplated by this Trust Agreement shall be sufficiently
    evidenced by an Officers' Certificate;

         (d)  whenever in the administration of this Trust Agreement, the
    Property Trustee shall deem it desirable that a matter be established
    before undertaking, suffering or omitting any action hereunder, the
    Property Trustee (unless other evidence is herein specifically prescribed)
    may, in the absence of bad faith on its part, request and rely upon an
    Officers' Certificate which, upon receipt of such request, shall be
    promptly delivered by the Depositor or the Administrative Trustees;

         (e)  the Property Trustee shall have no duty to see to any  recording,
    filing or registration of any instrument (including any financing or
    continuation statement or any filing under tax or securities laws) or any
    rerecording, refiling or reregistration thereof;

         (f)  the Property Trustee may consult with counsel (which counsel may
    be counsel to the Depositor or any of its Affiliates, and may include any
    of its employees) and the advice of such counsel shall be full and complete
    authorization and protection in respect of any action taken, suffered or
    omitted by it hereunder in good faith and in reliance thereon and in
    accordance with such advice; the Property Trustee shall have the right at
    any time to seek instructions concerning the administration of this Trust
    Agreement from any court of competent jurisdiction;

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

         (h)  the Property 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, debenture, note or other evidence of  indebtedness or other paper or
    document, unless requested in writing to do so by one or more
    Securityholders, but the Property Trustee may make such further inquiry or
    investigation into such facts or matters as it may see fit;

         (i)  the Property Trustee may execute any of the trusts or powers
    hereunder or perform any duties hereunder either directly or by or through
    its agents or attorneys, provided

                                         -32-



    that the Property Trustee shall be responsible for its own negligence or
    recklessness with respect to selection of any agent or attorney appointed
    by it hereunder;

         (j)  whenever in the administration of this Trust Agreement the
    Property Trustee shall deem it desirable to receive instructions with
    respect to enforcing any remedy or right or taking any other action
    hereunder the Property Trustee (i) may request instructions from the
    Holders of the Trust Securities which instructions may only be given by the
    Holders of the same proportion in Liquidation Amount of the Trust
    Securities as would be entitled to direct the Property Trustee under the
    terms of the Trust Securities in respect of such remedy, right or action,
    (ii) may refrain from enforcing such remedy or right or taking such other
    action until such instructions are received, and (iii) shall be protected
    in acting in accordance with such instructions; and

         (k)  except as otherwise expressly provided by this Trust Agreement,
    the Property Trustee shall not be under any obligation to take any action
    that is discretionary under the provisions of this Trust Agreement.

    No provision of this Trust Agreement shall be deemed to impose any duty or
obligation on the Property Trustee to perform any act or acts or exercise any
right, power, duty or obligation conferred or imposed on it, in any jurisdiction
in which it shall be illegal, or in which the Property Trustee shall be
unqualified or incompetent in accordance with applicable law, to perform any
such act or acts, or to exercise any such right, power, duty or obligation.  No
permissive power or authority available to the Property Trustee shall be
construed to be a duty.

    SECTION 804.   NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.  The
recitals contained herein and in the Trust Securities Certificates shall be
taken as the statements of the Trust, and the Trustees do not assume any
responsibility for their correctness.  The Trustees shall not be accountable for
the use or application by the Depositor of the proceeds of the Debentures.

    SECTION 805.   MAY HOLD SECURITIES.  Except as provided in the definition
of the term "Outstanding" in Article I, any Trustee or any other agent of any
Trustee or the Trust, in its individual or any other capacity, may become the
owner or pledgee of Trust Securities and, subject to Sections 808 and 813, may
otherwise deal with the Trust with the same rights it would have if it were not
a Trustee or such   other agent.

    SECTION 806.   COMPENSATION; INDEMNITY; FEES.  The Depositor agrees:

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

         (b)  except as otherwise expressly provided herein, to reimburse the
    Trustees upon request for all reasonable expenses, disbursements and
    advances incurred or made by the Trustees in accordance with any provision
    of this Trust Agreement (including the reasonable

                                         -33-



    compensation and the expenses and disbursements of its agents and counsel),
    except any such expense, disbursement or advance as may be attributable to
    its negligence or bad faith; and

         (c)  to indemnify each of the Trustees or any predecessor Trustee for,
    and to hold the Trustees harmless against, any loss, damage, claims,
    liability, penalty or expense incurred without negligence or bad faith on
    its part, arising out of or in connection with the acceptance or
    administration of this Trust Agreement, including the costs and expenses of
    defending itself against any claim or liability in connection with the
    exercise or performance of any of its powers or duties hereunder.

    No Trustee may claim any lien or charge on any Trust Property as a result
of any amount due pursuant to this Section 806.

    SECTION 807.   CORPORATE PROPERTY TRUSTEE REQUIRED; ELIGIBILITY OF
                   TRUSTEES.

    (a)  There shall at all times be a Property Trustee hereunder with respect
to the Trust Securities.  The Property Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $50,000,000.  If any such Person publishes
reports of condition at least annually, pursuant to law or to the requirements
of its supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such Person shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published.  If at any time the Property Trustee with respect to the
Trust Securities shall cease to be eligible in accordance with the provisions of
this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

    (b)  There shall at all times be one or more Administrative Trustees
hereunder with respect to the Trust Securities.  Each Administrative Trustee
shall be either a natural person who is at least 21 years of age or a legal
entity that shall act through one or more persons authorized to bind that
entity.

    (c)  There shall at all times be a Delaware Trustee with respect to the
Trust Securities.  The Delaware Trustee shall either be (i) a natural person who
is at least 21 years of age and a resident of the State of Delaware or (ii) a
legal entity with its principal place of business in the State of Delaware and
that otherwise meets the requirements of applicable Delaware law that shall act
through one or more persons authorized to bind such entity.

    SECTION 808.   CONFLICTING INTERESTS.  If the Property Trustee has or shall
acquire a conflicting interest within the meaning of the Trust Indenture Act,
the Property Trustee shall either eliminate such interest or resign, to the
extent and in the manner provided by, and subject to the provisions of, the
Trust Indenture Act and this Trust Agreement.

    SECTION 809.   CO-TRUSTEES AND SEPARATE TRUSTEE.  Unless an Event of
Default shall have occurred and be continuing, at any time or times, for the
purpose of meeting the legal requirements of the Trust Indenture Act or of any
jurisdiction in which any part of the Trust Property may at the time be located,
the Depositor and the Administrative Trustees, by agreed action of the

                                         -34-



majority of such Trustees, shall have power to appoint, and upon the written
request of the Administrative Trustees, the Depositor shall for such purpose
join with the Administrative Trustees in the execution, delivery and performance
of all instruments and agreements necessary or proper to appoint, one or more
Persons approved by the Property Trustee either to act as co-trustee, jointly
with the Property Trustee, of all   or any part of such Trust Property, or to
the extent required by law to act as separate trustee of any such property, in
either case with such powers as may be provided in the instrument of
appointment, and to vest in such Person or Persons in the capacity aforesaid,
any property, title, right or power deemed necessary or desirable, subject to
the other provisions of this Section.  If   the Depositor does not join in such
appointment within 15 days after the receipt by it of a request so to do, or in
case a Debenture Event of Default has occurred and is continuing, the Property
Trustee alone shall have power to make such appointment.  Any co-trustee or
separate trustee appointed pursuant to this Section shall either be (i) a
natural person who is at least 21 years of age and a resident of the United
States or (ii) a legal entity with its principal place of business in the United
States that shall act through one or more persons authorized to bind such
entity.

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

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

         (a)  The Trust Securities shall be executed and delivered and all
    rights, powers, duties and obligations hereunder in respect of the custody
    of securities, cash and other personal property held by, or required to be
    deposited or pledged with, the Trustees specified hereunder, shall be
    exercised, solely by such Trustees and not by such co-trustee or separate
    trustee.

         (b)  The rights, powers, duties and obligations hereby conferred or
    imposed upon the Property Trustee in respect of any property covered by
    such appointment shall be conferred or imposed upon and exercised or
    performed by the Property Trustee or by the Property Trustee and such
    co-trustee or separate trustee jointly, as shall be provided in the
    instrument appointing such co-trustee or separate trustee, except to the
    extent that under any law of any jurisdiction in which any particular act
    is to be performed, the Property Trustee shall be incompetent or
    unqualified to perform such act, in which event such rights, powers, duties
    and obligations shall be exercised and performed by such co-trustee or
    separate trustee.

         (c)  The Property Trustee at any time, by an instrument in writing
    executed by it, with the written concurrence of the Depositor, may accept
    the resignation of or remove any co-trustee or separate trustee appointed
    under this Section, and, in case a Debenture Event of Default has occurred
    and is continuing, the Property Trustee shall have power to accept the
    resignation of, or remove, any such co-trustee or separate trustee without
    the concurrence of the Depositor.  Upon the written request of the Property
    Trustee, the Depositor shall join with the Property Trustee in the
    execution, delivery and performance of all instruments and

                                         -35-



    agreements necessary or proper to effectuate such resignation or removal.
    A successor to any co-trustee or separate trustee so resigned or removed
    may be appointed in the manner provided in this Section.

         (d)  No co-trustee or separate trustee hereunder shall be personally
    liable by reason of any act or omission of the Property Trustee or any
    other trustee hereunder.

         (e)  The Property Trustee shall not be liable by reason of any act of
    a co-trustee or separate trustee.

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

    SECTION 810.   RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.  No
resignation or removal of any Trustee (the "Relevant Trustee") and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 811.

    Subject to the immediately preceding paragraph, the Relevant Trustee may
resign at any time with respect to the Trust Securities by giving written
notice thereof to the Securityholders.  If the instrument of acceptance by the
successor Trustee required by Section 811 shall not have been delivered to the
Relevant Trustee within 30 days after the giving of such notice of
resignation, the Relevant Trustee may petition, at the expense of the Company,
any court of competent jurisdiction for the appointment of a successor Relevant
Trustee with respect to the Trust Securities.

    Unless a Debenture Event of Default shall have occurred and be continuing,
any Trustee may be removed at any time by Act of the Common   Securityholder.
If a Debenture Event of Default shall have occurred and be continuing, the
Property Trustee or the Delaware Trustee, or both of them, may   be removed at
such time by Act of the Holders of a majority in Liquidation   Amount of the
Preferred Securities, delivered to the Relevant Trustee (in its individual
capacity and on behalf of the Trust).  An Administrative Trustee may be removed
by the Common Securityholder at any time.

    If any Trustee shall resign, be removed or become incapable of acting as
Trustee, or if a vacancy shall occur in the office of any Trustee for any cause,
at a time when no Debenture Event of Default shall have occurred and be
continuing, the Common Securityholder, by Act of the Common Securityholder
delivered to the retiring Trustee, shall promptly appoint a successor Trustee or
Trustees with respect to the Trust Securities and the Trust, and the successor
Trustee shall comply with the applicable requirements of Section 811.  If the
Property Trustee or the Delaware Trustee shall resign, be removed or become
incapable of continuing to act as the Property Trustee or the Delaware Trustee,
as the case may be, at a time when a Debenture Event of Default shall have
occurred and be continuing, the Preferred Securityholders, by Act of the
Securityholders of a majority in Liquidation Amount of the Preferred Securities
then Outstanding delivered to the retiring Relevant Trustee, shall promptly
appoint a successor Relevant Trustee or Trustees with respect to the Trust
Securities and the Trust, and such successor Trustee shall comply with the
applicable requirements

                                         -36-



of Section 811.  If an Administrative Trustee shall resign, be removed or become
incapable of acting as Administrative Trustee, at a time when a Debenture Event
of Default shall   have occurred and be continuing, the Common Securityholder,
by Act of the Common Securityholder delivered to the Administrative Trustee,
shall promptly appoint a successor Administrative Trustee or Administrative
Trustees with respect to the Trust Securities and the Trust, and such successor
Administrative Trustee or Administrative Trustees shall comply with the
applicable requirements of Section 811.  If no successor Relevant Trustee with
respect to the Trust Securities shall have been so appointed by the Common
Securityholder or the Preferred Securityholders and accepted appointment in the
manner required by Section 811, any Securityholder who has been a Securityholder
of Trust Securities for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
appointment of  a successor Relevant Trustee with respect to the Trust
Securities.

    The Property Trustee shall give notice of each resignation and each removal
of a Trustee and each appointment of a successor Trustee to all Securityholders
in the manner provided in Section 1008 and shall give notice to the Depositor.
Each notice shall include the name of the successor Relevant Trustee and the
address of its Corporate Trust Office if it is the Property Trustee.

    Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Delaware Trustee who is
a natural person dies or becomes, in the opinion of the Depositor, incompetent
or incapacitated, the vacancy created by such death, incompetence or incapacity
may be filled by (a) the unanimous act of remaining Administrative Trustees if
there are at least two of them or (b) otherwise by the Depositor (with the
successor in each case being a Person who satisfies the eligibility requirement
for Administrative Trustees set forth in Section 807).

    SECTION 811.   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.  In case of the
appointment hereunder of a successor Trustee such successor Trustee so appointed
shall execute, acknowledge and deliver to the Trust 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 Depositor 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 if the Property Trustee is the resigning Trustee shall duly assign, transfer
and deliver to the successor Trustee all property and money held by such
retiring Property Trustee hereunder.

    In case of the appointment hereunder of a successor Relevant Trustee with
respect to the Trust Securities and the Trust, the retiring Relevant Trustee and
each successor Relevant Trustee with respect to the Trust Securities shall
execute and deliver an amendment hereto wherein each   successor Relevant
Trustee shall accept such appointment and which (a) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Relevant Trustee all the rights, powers, trusts and
duties of the retiring Relevant Trustee with respect to the   Trust Securities
and the Trust and (b) shall add to or change any of the provisions of this Trust
Agreement as shall be necessary to provide for or facilitate the administration
of the trusts hereunder

                                         -37-



by more than one Relevant Trustee, it being understood that nothing herein or in
such amendment shall constitute such Relevant Trustees co-trustees of the same
trust and that each such Relevant Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Relevant Trustee and upon the execution and delivery of such
amendment the resignation or removal of the retiring Relevant Trustee shall
become effective to the extent provided therein and each such successor Relevant
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Relevant Trustee with
respect to the Trust Securities and the Trust; but, on request of   the Trust or
any successor Relevant Trustee such retiring Relevant Trustee shall duly assign,
transfer and deliver to such successor Relevant Trustee all Trust Property, all
proceeds thereof and money held by such retiring Relevant Trustee hereunder with
respect to the Trust Securities and the Trust.

    Upon request of any such successor Relevant Trustee, the Trust shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Relevant Trustee all such rights, powers and trusts
referred to in the first or second preceding paragraph, as the case may be.

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

    SECTION 812.   MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.
Any corporation into which the Property Trustee or the Delaware 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 such Relevant
Trustee shall be a party, or any corporation succeeding to all or substantially
all the corporate trust business of such Relevant Trustee, shall be the
successor of such Relevant Trustee hereunder, provided such corporation shall be
otherwise qualified and eligible under this Article, without the execution or
filing of any paper or any further act on the part of any of the parties hereto.

    SECTION 813.   PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR OR
TRUST.  If and when the Property Trustee or the Delaware Trustee shall be or
become a creditor of the Depositor or the Trust (or any other obligor upon the
Debentures or the Trust Securities), the Property Trustee or the Delaware
Trustee, as the case may be, shall be subject to and shall take all actions
necessary in order to comply with the provisions of the Trust Indenture Act
regarding the collection of claims against the Depositor or Trust (or any such
other obligor).

    SECTION 814.   REPORTS BY PROPERTY TRUSTEE.  (a)  Not later than July 15 of
each year commencing with July 15, 1997, the Property Trustee shall transmit to
all Securityholders in accordance  with Section 1008, and to the Depositor, a
brief report dated as of such December 31 with respect to:

         (i)  its eligibility under Section 807 or, in lieu thereof, if to the
    best of its knowledge it has continued to be eligible under said Section, a
    written statement to such effect;

                                         -38-



         (ii) a statement that the Property Trustee has complied with all of
    its obligations under this Trust Agreement during the twelve-month period
    (or, in the case of the initial report, the period since the Closing Date)
    ending with such December 31 or, if the Property Trustee has not complied
    in any material respect with such obligations, a description of such
    noncompliance; and

         (iii)  any change in the property and funds in its possession as
    Property Trustee since the date of its last report and any action taken by
    the Property Trustee in the performance of its duties hereunder which it
    has not previously reported and which in its opinion materially affects the
    Trust Securities.

    (b)  In addition, the Property Trustee shall transmit to Securityholders
such reports concerning the Property Trustee and its actions under this Trust
Agreement as may be required pursuant to the Trust Indenture Act at the times
and in the manner provided pursuant thereto.

    (c)  A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Property Trustee with each national securities
exchange, the Nasdaq National Market or such other interdealer quotation system
or self-regulatory organization upon which the Trust Securities are listed or
traded, with the Commission and with the Depositor.

    SECTION 815.   REPORTS TO THE PROPERTY TRUSTEE.  The Depositor and the
Administrative Trustees on behalf of the Trust shall provide to the Property
Trustee such documents, reports and information as required by Section 314 of
the Trust Indenture Act (if any) and the compliance certificate required by
Section 314(a) of the Trust Indenture Act   in the form, in the manner and at
the times required by Section 314 of the Trust Indenture Act.

    SECTION 816.   EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT.  Each of
the Depositor and the Administrative Trustees on behalf of the Trust shall
provide to the Property Trustee such evidence of compliance with any conditions
precedent, if any, provided for in this Trust Agreement   that relate to any of
the matters set forth in Section 314(c) of the Trust   Indenture Act.  Any
certificate or opinion required to be given by an officer   pursuant to Section
314(c)(1) of the Trust Indenture Act shall be given in the   form of an
Officers' Certificate.

    SECTION 817.   NUMBER OF TRUSTEES.  (a)  The number of Trustees shall be
four, provided that the Holder of all of the Common Securities by written
instrument may increase or decrease the number of Administrative Trustees.  The
Property Trustee and the Delaware Trustee may be the same person.

    (b)  If a Trustee ceases to hold office for any reason and the number of
Administrative Trustees is not reduced pursuant to Section 817(a), or if the
number of Trustees is increased pursuant to Section 817(a), a vacancy shall
occur.  The vacancy shall be filled with a Trustee appointed in   accordance
with Section 810.

    (c)  The death, resignation, retirement, removal, bankruptcy, incompetence
or incapacity to perform the duties of a Trustee shall not operate to annul the
Trust.  Whenever a vacancy in the

                                         -39-




number of Administrative Trustees shall occur, until such vacancy is filled by
the appointment of an Administrative Trustee in accordance with Section 810, the
Administrative Trustees in office, regardless of their number (and
notwithstanding any other provision of this Agreement), shall have all the
powers granted to the Administrative Trustees and shall discharge all the
duties imposed upon the Administrative Trustees by this Trust Agreement.

    SECTION 818.   DELEGATION OF POWER.  (a)  Any Administrative Trustee may,
by power of attorney consistent with applicable law, delegate to any other
natural person over the age of 21 his or her power for the purpose of executing
any documents contemplated in Section 207(a), including any registration
statement or amendment thereto filed with the Commission, or making any other
governmental filing.

    (b)  The Administrative Trustees shall have power to delegate from time to
time to such of their number or to the Depositor the doing of such things and
the execution of such instruments either in the name of the Trust or the names
of the Administrative Trustees or otherwise as the Administrative Trustees may
deem expedient, to the extent such delegation is not prohibited  by applicable
law or contrary to the provisions of the Trust, as set forth herein.


                                      ARTICLE IX

                         TERMINATION, LIQUIDATION AND MERGER

    SECTION 901.   TERMINATION UPON EXPIRATION DATE.  Unless earlier 
terminated, the Trust shall automatically terminate on ________, ____ (the 
"Expiration Date"), following the distribution of the Trust Property in 
accordance with Section 904.

    SECTION 902.   EARLY TERMINATION.  The first to occur of any of the
following events is an "Early Termination Event":

         (a)  the occurrence of a Bankruptcy Event in respect of, or the
    dissolution or liquidation of, the Depositor;

         (b)  the written direction to the Property Trustee from the Depositor
    at any time (which direction is optional and wholly within the discretion
    of the Depositor) to terminate the Trust and distribute the Debentures in
    exchange for the Preferred Securities;

         (c)  the redemption of all of the Preferred Securities in connection
    with the redemption of all of the Debentures; and

         (d)  the entry of an order for dissolution of the Trust by a court of
    competent jurisdiction.

    SECTION 903.   TERMINATION.  The respective obligations and
responsibilities of the Trustees and the Trust created and continued hereby
shall terminate upon the latest to occur of the

                                         -40-



following:  (a) the distribution by the Property Trustee to Securityholders upon
the liquidation of the Trust pursuant to Section 904, or upon the redemption of
all of the Trust Securities pursuant to Section 402, of   all amounts required
to be distributed hereunder upon the final payment of the Trust Securities; (b)
the payment of any expenses owed by the Trust; and (c) the discharge of all
administrative duties of the Administrative Trustees, including the performance
of any tax reporting obligations with respect to the Trust or the
Securityholders.

    SECTION 904.   LIQUIDATION.  (a)  If an Early Termination Event specified
in clause (a), (b) or (d) of Section 902 occurs or upon the Expiration Date, the
Trust shall be liquidated by the Trustees as expeditiously as the Trustees
determine to be possible by distributing, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, to each Securityholder a
Like Amount of Debentures, subject to Section 904(d).  Notice of liquidation
shall be given by the Property Trustee by first-class mail, postage prepaid,
mailed not later than 30 nor more than 60 days prior to the Liquidation Date to
each Holder of Trust Securities at such Holder's address appearing in the
Securities Register. All notices of liquidation shall:

         (i)   state the Liquidation Date;

         (ii)  state that from and after the Liquidation Date, the Trust
    Securities will no longer be deemed to be Outstanding and any Trust
    Securities Certificates not surrendered for exchange will be deemed to
    represent a Like Amount of Debentures; and

         (iii) provide such information with respect to the mechanics by which
    Holders may exchange Trust Securities Certificates for Debentures, or if
    Section 904(d) applies receive a Liquidation Distribution, as the
    Administrative Trustees or the Property Trustee shall deem appropriate.

    (b)  Except where Section 902(c) or 904(d) applies, in order to effect the
liquidation of the Trust and distribution of the Debentures to Securityholders,
the Property Trustee shall establish a record date for such distribution (which
shall be not more than 45 days prior to the Liquidation Date) and, either itself
acting as exchange agent or through the appointment of a separate exchange
agent, shall establish such procedures as it shall deem appropriate to effect
the distribution of  Debentures in exchange for the Outstanding Trust Securities
Certificates.

    (c)  Except where Section 902(c) or 904(d) applies, after the Liquidation
Date, (i) the Trust Securities will no longer be deemed to be Outstanding, (ii)
certificates representing a Like Amount of Debentures will be issued to holders
of Trust Securities Certificates, upon surrender of such certificates to the
Administrative Trustees or their agent for exchange, (iii) the Depositor shall
use its reasonable efforts to have the Debentures listed on the New York Stock
Exchange or on such other stock exchange, interdealer quotation system or
self-regulatory organization as the Preferred Securities are then listed or
traded, (iv) any Trust Securities Certificates not so surrendered for exchange
will be deemed to represent a Like Amount of Debentures, accruing interest at
the rate provided for in the Debentures from the last Distribution Date on which
a Distribution was made on such Trust Securities Certificates until such
certificates are so surrendered (and until such certificates are so surrendered,
no payments of interest or principal will be made to holders of Trust Securities

                                         -41-



Certificates with respect to such Debentures), and (v) all rights of
Securityholders holding Trust Securities will cease, except the right of such
Securityholders to receive Debentures upon surrender of Trust Securities
Certificates.

    (d)  In the event that, notwithstanding the other provisions of this
Section 904, whether because of an order for dissolution entered by a court of
competent jurisdiction or otherwise, distribution of the Debentures in the
manner provided herein is determined by the Property Trustee not to be
practical, the Trust Property shall be liquidated, and the Trust shall be
dissolved, wound-up or terminated, by the Property Trustee in such manner as the
Property Trustee determines.  In such event, on the date of the dissolution,
winding-up or other termination of the Trust, Securityholders will be entitled
to receive out of the assets of the Trust available for distribution to
Securityholders, after satisfaction of liabilities to creditors of the Trust as
provided by applicable law, an amount equal to the Liquidation Amount per Trust
Security plus accumulated and unpaid Distributions thereon to the date of
payment (such amount being the "Liquidation Distribution").  If, upon any such
dissolution, winding-up or termination, 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, subject to the next succeeding
sentence, the amounts payable by the Trust on the Trust Securities shall be paid
on a pro rata basis (based upon Liquidation Amounts).  The holder of the Common
Securities will be entitled to receive Liquidation Distributions upon any such
dissolution, winding-up or termination pro rata (determined as aforesaid) with
Holders of Preferred Securities, except that, if a Debenture Event of Default
has occurred and is continuing, the Preferred Securities shall have a priority
over the Common Securities.

    SECTION 905.   MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF
THE TRUST.  The Trust may not merge with or into, consolidate, amalgamate, or be
 replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other body, except pursuant
to this Section 905.  At the request of the Depositor, with the consent of the
Administrative Trustees and without the consent of the holders of the
Preferred Securities, the Trust may merge with or into, consolidate, amalgamate,
or be replaced by or convey, transfer or lease its properties and assets
substantially as an entirety to a trust organized as such under the   laws of
any state; provided, that (i) such successor entity either (a) expressly assumes
all of the obligations of the Trust with respect to the Preferred Securities or
(b) substitutes for the Preferred Securities other securities having
substantially the same terms as the Preferred Securities (the "Successor
Securities") so long as the Successor Securities rank the same as the Preferred

liquidation, redemption and otherwise, (ii) the Depositor expressly appoints a
trustee of such successor entity possessing the same powers and duties as the
Property Trustee as the holder of the Debentures, (iii) the Successor Securities

notification of issuance, on any national securities exchange or other

                                         -42-



consolidation, amalgamation, replacement, conveyance, transfer or lease, the
Depositor has received an Opinion of Counsel to the effect that (a) such merger,
consolidation, amalgamation,   replacement, conveyance, transfer or lease does
not adversely affect the rights, preferences and privileges of the holders of
the Preferred Securities (including any Successor Securities) in any material
respect, and (b) following such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease, neither the Trust nor such successor
entity will be required to register as an investment company under the 1940 Act
and (viii) the Depositor owns all of the Common Securities of such successor
entity and guarantees the obligations of such successor entity under the
Successor Securities at least to the extent provided by the Guarantee.
Notwithstanding the foregoing, the Trust shall not, except with the consent of
holders of 100%   in Liquidation Amount of the Preferred Securities,
consolidate, amalgamate, merge with or into, be replaced by or convey, transfer
or lease its properties and assets substantially as an entirety to any other
entity or permit any other entity to consolidate, amalgamate, merge with or
into, or replace it if such consolidation, amalgamation, merger, replacement,
conveyance, transfer or lease would cause the Trust or the successor entity to
be classified as other than a grantor trust for United States federal income tax
purposes.

    SECTION 1001.  LIMITATION OF RIGHTS OF SECURITYHOLDERS.  The death or
incapacity of any person having an interest, beneficial or otherwise, in Trust
Securities shall not operate to terminate this Trust Agreement, nor entitle the
legal representatives or heirs of such person or   any Securityholder for such
person, to claim an accounting, take any action or bring any proceeding in any
court for a partition or winding-up of the   arrangements contemplated hereby,
nor otherwise affect the rights, obligations and liabilities of the parties
hereto or any of them.

Securityholders,  (i) to cure any ambiguity, correct or supplement any provision
herein which may be inconsistent with any other provision herein, or to make any
other provisions with respect to matters or questions arising under this Trust
Agreement, which shall not be inconsistent with the other provisions of this
Trust Agreement, or (ii) to modify, eliminate or add to any provisions of this
Trust Agreement to such extent as shall be necessary to ensure that  the Trust
will be classified for United States federal income tax purposes as a grantor
trust at all times that any Trust Securities are outstanding or to ensure that
the Trust will not be required to register as an investment company under the
1940 Act; provided, however, that in the case of clause (i), such action shall
not adversely affect in any material respect the interests of any
Securityholder, and any amendments of this Trust Agreement shall become
effective when notice thereof is given to the Securityholders.

    (b)  Except as provided in Section 1002(c) hereof, any provision of this
Trust Agreement may be amended by the Trustees and the Depositor with (i) the
consent of Securityholders representing not less than a majority (based upon
Liquidation Amounts) of the Trust Securities then Outstanding and (ii) receipt
by the Trustees of an Opinion of Counsel to the effect that such

                                         -43-



amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's status as a grantor trust for
United States federal income tax purposes or the Trust's exemption from status
of an investment company under the 1940 Act.

    (c)  In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Securityholder (such consent

specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date; notwithstanding
any other provision herein, without the unanimous consent of the Securityholders
(such consent being obtained in accordance with Section 603 or 606 hereof), this
paragraph (c) of this Section 1002 may not be amended.

    (d)  Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement

status of an investment company under the 1940 Act or fail or cease to be
classified as a grantor trust for United States federal  income tax purposes.

    (e)  Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Depositor, this Trust Agreement may not be amended in
a manner which imposes any additional obligation on the Depositor.

Administrative Trustees shall promptly provide to the Depositor a copy of such
amendment.

succeeding day that is a Business Day (except as otherwise

                                         -44-

the Trust under any bankruptcy, insolvency, reorganization or other similar law
(including, without limitation, the United States Bankruptcy Code)
(collectively, "Bankruptcy Laws") or otherwise join in the commencement of any
proceeding against the Trust under any Bankruptcy Law.   In the event the

                                         -45-

control.  If any provision of this Trust Agreement modifies or excludes any
provision of the Trust Indenture Act which may be so modified or excluded, the
latter provision shall be deemed to apply to this Trust Agreement as so modified
or excluded, as the case may be.

    (d)  The application of the Trust Indenture Act to this Trust Agreement
shall not affect the nature of the Securities as equity securities representing
undivided beneficial interests in the assets of the Trust.

    SECTION 1011.  ACCEPTANCE OF TERMS OF TRUST AGREEMENT, GUARANTEE AND
INDENTURE.  THE RECEIPT AND ACCEPTANCE OF A TRUST SECURITY OR ANY INTEREST
THEREIN BY OR ON BEHALF OF A SECURITYHOLDER OR ANY BENEFICIAL OWNER, WITHOUT ANY
SIGNATURE OR FURTHER MANIFESTATION OF ASSENT, SHALL CONSTITUTE THE UNCONDITIONAL
ACCEPTANCE BY THE SECURITYHOLDER AND ALL OTHERS HAVING A BENEFICIAL INTEREST IN
SUCH TRUST SECURITY OF ALL THE TERMS AND PROVISIONS OF THIS TRUST AGREEMENT AND
AGREEMENT TO THE SUBORDINATION PROVISIONS AND OTHER TERMS OF THE GUARANTEE AND
THE INDENTURE, AND SHALL CONSTITUTE THE AGREEMENT OF THE TRUST, SUCH
SECURITYHOLDER AND SUCH OTHERS THAT THE TERMS AND PROVISIONS OF THIS TRUST
AGREEMENT SHALL BE BINDING, OPERATIVE AND EFFECTIVE AS BETWEEN THE TRUST AND
SUCH SECURITYHOLDER AND SUCH OTHERS.

Re:      NVP CAPITAL I   % CUMULATIVE QUARTERLY INCOME
         PREFERRED SECURITIES, SERIES A


Ladies and Gentlemen:

         The purpose of this letter is to set forth certain matters relating to
the issuance and deposit with The Depository Trust Company ("DTC") of the NVP
Capital I ____% Cumulative Quarterly Income Preferred Securities, Series A (the
"Preferred Securities"), of NVP Capital I, a Delaware business trust (the
"Issuer"), formed pursuant to a Trust Agreement between Nevada Power Company
("NVP") and ________________________, as Trustee.  The payment of distributions
on the Preferred Securities and payments due upon liquidation of Issuer or
redemption of the Preferred Securities, to the extent the Issuer has funds
available for the payment thereof, are guaranteed by NVP to the extent set forth
in a Guarantee Agreement dated ______, 1997 by NVP with respect to the Preferred
Securities.  NVP and the Issuer propose to sell the Preferred Securities to
certain Underwriters (the "Underwriters") pursuant to an Underwriting Agreement
dated ______, 1997 by and among the Underwriters, the Issuer and NVP, and the
Underwriters wish to take delivery of the Preferred Securities through DTC.
________________________ is acting as transfer agent and registrar with respect
to the Preferred Securities (the "Transfer Agent and Registrar").

         To induce DTC to accept the Preferred Securities as eligible for
deposit at DTC, and to act in accordance with DTC's rules with respect to the
Preferred Securities, the Issuer, the Transfer Agent and Registrar and DTC agree
among each other as follows:

         1.   Prior to the closing of the sale of the Preferred Securities to
the Underwriters, which is expected to occur on or about ______, 1997, there
shall be deposited with DTC one or more global certificates (individually and
collectively, the "Global Certificate")
registered in the name of DTC's Preferred Securities nominee, Cede & Co.,
representing an aggregate of 5,000,000 Preferred Securities and bearing the
following legend:

         Unless this certificate is presented by an authorized
         representative of The  Depository Trust Company, a New York
         corporation ("DTC"), to Issuer or its agent for registration
         of transfer, exchange, or payment, and any certificate
         issued is registered in the name of Cede & Co. or in such
         other name as is requested by an authorized representative
         of DTC (and any  payment is made to Cede & Co. or to such
         other entity as is requested by an authorized 


                                         B-1


         representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF 
         FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the
         registered owner hereof, Cede & Co., has an interest herein.

         2.   The Amended and Restated Trust Agreement of the Issuer provides
for the voting by holders of the Preferred Securities under certain limited
circumstances.  The Issuer shall establish a record date for such purposes and
shall, to the extent possible, give DTC notice of such record date not less than
15 calendar days in advance of such record date.

         3.   In the event of a stock split, conversion, recapitalization,
reorganization or any other similar transaction resulting in the cancellation of
all or any part of the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice of such event at least 5
business days prior to the effective date of such event.

         4.   In the event of distribution on, or an offering or issuance of
rights with respect to, the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice specifying:  (a) the amount
of and conditions, if any, applicable to the payment of any such distribution or
any such offering or issuance of rights; (b) any applicable expiration or
deadline date, or any date by which any action on the part of the holders of
Preferred Securities is required; and (c) the date any required notice is to be
mailed by or on behalf of the Issuer to holders of Preferred Securities or
published by or on behalf of the Issuer (whether by mail or publication, the
"Publication Date"). Such notice shall be sent to DTC by a secure means  (e.g.,
legible telecopy, registered or certified mail, overnight delivery) in a timely
manner designed to assure that such notice is in DTC's possession no later than
the close of business on the business day before the Publication Date. The
Issuer or the Transfer Agent and Registrar will forward such notice either in a
separate secure transmission for each CUSIP number or in a secure transmission
of multiple CUSIP numbers (if applicable) that includes a manifest or list of
each CUSIP number submitted in that transmission. (The party sending such notice
shall have a method to verify subsequently the use of such means and the
timeliness Of such notice.) The Publication Date shall be not less than 30
calendar days nor more than 60 calendar days prior to the payment of any such
distribution or any such offering or issuance of rights with respect to the
Preferred Securities. After establishing the amount of payment to be made on the
Preferred Securities, the Issuer or the Transfer Agent and Registrar will notify
DTC's Dividend Department of such payment 5 business days prior to payment date.
Notices to DTC's Dividend Department by telecopy shall be sent to (212) 709-

receipt of such telecopy by telephoning the Dividend Department at (212)

         5.   In the event of a redemption by the Issuer of the Preferred
Securities, notice specifying the terms of the redemption and the Publication
Date of such notice shall be sent by the Issuer or the Transfer Agent and
Registrar to DTC not less than 30 calendar days prior to such event by a secure
means in the manner set forth in paragraph 4.  Such redemption notice shall be
sent to DTC's Call Notification Department at (516) 227-4164 or (516) 227-4190,

         7.   All notices and payment advices sent to DTC shall contain the
CUSIP number or numbers of the Preferred Securities and the accompanying
designation of the Preferred Securities, which, as of the date of this letter,
is "NVP Capital I ____% Cumulative Quarterly Income Preferred Securities, Series
A".

         8.   Distribution payments or other cash payments with respect to the
Preferred Securities evidenced by the Global Certificate shall be received by
Cede & Co., as nominee of DTC, or its registered assigns in next day funds on

         9.   DTC may by prior written notice direct the Issuer and the
Transfer Agent and Registrar to use any other telecopy number or address of DTC
as the number or address to which notices or payments may be sent.

         10.  In the event of a conversion, redemption, or any other similar

Transfer Agent and Registrar's invitation) necessitating a reduction in the
aggregate number of Preferred Securities outstanding evidenced by the Global
Certificate, DTC, in its discretion:   (a) may request the Issuer or the

or (b) may make an appropriate notation on the Global Certificate indicating the
date and amount of such reduction.

         11.  DTC may discontinue its services as a securities depositary with
respect to the Preferred Securities at any time by giving at least 90 days'
prior written notice to the Issuer and the Transfer Agent and Registrar (at
which time DTC will confirm with the Issuer or the Transfer Agent and Registrar
the aggregate number of Preferred Securities deposited with it) and discharging
its responsibilities with respect thereto under applicable law.  Under such
circumstances, the Issuer may determine to make alternative arrangements for
book-entry settlement for the Preferred Securities, make available one or more
separate global certificates evidencing Preferred Securities to any Participant
having Preferred Securities credited to its DTC account, or issue definitive
Preferred Securities to the beneficial holders thereof, and in any such case,
DTC agrees to cooperate fully with the Issuer and the Transfer Agent and
Registrar and to return the Global Certificate, duly endorsed for transfer as
directed by the Issuer or the Transfer Agent and Registrar, together with any
other documents of transfer reasonably requested by the Issuer or the Transfer
Agent and Registrar.

         12.  In the event that the Issuer determines that beneficial owners of
Preferred Securities shall be able to obtain definitive Preferred Securities,
the Issuer or the Transfer Agent and Registrar shall notify DTC of the
availability of certificates.  In such event, the Issuer or the Transfer Agent
and Registrar shall issue, transfer and exchange certificates in appropriate
amounts, as required by DTC and others, and DTC agrees to cooperate fully with
the Issuer and the Transfer Agent and Registrar and to return the Global
Certificate, duly endorsed for transfer as directed by the Issuer or the
Transfer Agent and Registrar, together with any other documents of transfer
reasonably requested by the Issuer or the Transfer Agent and Registrar.

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

waives any right or remedy to require that any action be brought against the
Trust or any other person or entity before proceeding against NVP.

         Section 1.6.   SUBROGATION.

         NVP shall be subrogated to all (if any) rights of the Trust in respect
of any amounts paid to the Beneficiaries by NVP under this Agreement; provided,
