or duly made available for payment, monthly, quarterly,
semiannually or annually, as specified above as the Interest
Payment Period, and on the Interest Payment Dates specified
above, in each year commencing on the first Interest Payment Date
next succeeding the Original Issue Date specified above, unless
the Original Issue Date occurs between a Regular Record Date, as
defined below, and the next succeeding Interest Payment Date, in
which case commencing on the second Interest Payment Date
succeeding the Original Issue Date, to the registered holder of
this bond on the Regular Record Date with respect to such
Interest Payment Date, and on the Maturity Date shown above (or
any Redemption Date as described on the reverse hereof or any
Optional Repayment Date specified above).  Interest on this bond
will accrue from the most recent Interest Payment Date to which
interest has been paid or duly provided for or, if no interest
has been paid, from the Original Issue Date specified above,
until the principal hereof has been paid or duly made available
for payment.  If the Maturity Date (or any Redemption Date or any
Optional Repayment Date) or an Interest Payment Date falls on a
day which is not a Business Day as defined below, principal or
interest payable with respect to such Maturity Date (or
Redemption Date or Optional Repayment Date) or Interest Payment
Date will be paid on the next succeeding Business Day with the
same force and effect as if made on such Maturity Date (or
Redemption Date or Optional Repayment Date) or Interest Payment
Date, as the case may be, and no interest shall accrue for the
period from and after such Maturity Date (or Redemption Date or
Optional Repayment Date) or Interest Payment Date.  The interest
so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, subject to certain exceptions, be
paid to the person in whose name this bond (or one or more
predecessor bonds) is registered at the close of business on the
fifteenth day (whether or not a Business Day) next preceding such
Interest Payment Date (the "Regular Record Date"); provided,
however, that interest payable on the Maturity Date (or any
Redemption Date or any Optional Repayment Date) will be payable
to the person to whom the principal hereof shall be payable. 
Should the Company default in the payment of interest ("Defaulted
Interest"), the Defaulted Interest shall be paid to the person in
whose name this bond (or one or more predecessor bonds) is
registered on a subsequent record date fixed by the Company,
which subsequent record date shall be fifteen (15) days prior to
the payment of such Defaulted Interest.  As used herein,
"Business Day" means any day, other than a Saturday or Sunday, on
which banks in The City of New York are not required or
authorized by law to close.

   Payment of the principal of and interest on this bond will be
made in immediately available funds at the office or agency of
the Company maintained for that purpose in the Borough of
Manhattan, The City of New

York, in such coin or currency of the United States of America as
at the time of payment is legal tender for payment of public and
private debts; provided, however, that payment of interest on any
Interest Payment Date other than the Maturity Date (or any
Redemption Date or any Optional Repayment Date) may be made at
the option of the Company by check mailed to the address of the
person entitled thereto as such address shall appear in the bond
register of the Company.  A person holding $10,000,000 or more in
aggregate principal amount of bonds having the same Interest
Payment Date (whether having identical or different terms and
provisions) will be entitled to receive payments of interest by
wire transfer of immediately available funds if appropriate
written wire transfer instructions have been received by the
Trustee not less than sixteen days prior to the applicable
Interest Payment Date.

   Reference is hereby made to the further provisions of this
bond set forth on the reverse hereof, and such further provisions
shall for all purposes have the same effect as though fully set
forth at this place.

   This bond shall not become or be valid or obligatory for any
purpose until the authentication certificate hereon shall have
been signed by the Trustee.

specific series) by an Indenture of Mortgage and Deed of Trust
dated July 1, 1945, duly executed and delivered by the Company to
The Marine Midland Trust Company of New York (now Marine Midland

hereof shall be at least $100,000) at the option of the holder
hereof at a repayment price equal to 100% of the principal amount
to be repaid, together with interest thereon payable to the date
of repayment.  For this bond to be repaid in whole or in part at

called a "Redemption Date".

   The "Regular Redemption Price" shall initially be the Initial
Regular Redemption Percentage, shown on the face hereof, of the
principal amount of this bond to be redeemed and shall decline at
each anniversary of the Initial Regular Redemption Date, shown on
the face hereof, by the Annual Regular Redemption Percentage
Reduction, if any, shown on the face hereof, of the principal
amount to be redeemed until the Regular Redemption Price is 100%
of such principal amount.

   The Bonds may be redeemed prior to maturity as a whole at any
time or in part from time to time (in increments as specified in
the second preceding paragraph) in the instances provided in the
Indenture by the application of proceeds of the sale or
disposition substantially as an entirety of the Company's
electric properties at Portland, Oregon, upon payment of the
principal amount thereof, together with interest accrued to the
date of such redemption, on notice given as provided in such
second preceding paragraph.

   Interest payments on this bond will include interest accrued
to but excluding the Interest Payment Date or the Maturity Date,
as the case may be.  Interest payments for this bond will be
computed and paid on the basis of a 360-day year of twelve 30-day
months.

   If this bond or any portion thereof ($1,000 or an integral
multiple thereof) is duly called for redemption and payment duly
provided for as specified in the Indenture, this bond or such
portion thereof shall cease to be entitled to the lien of the
Indenture from and after the date payment is so provided for and
shall cease to bear interest from and after the redemption date
fixed for such redemption.

   In the event of the selection for redemption of a portion only
of the principal of this bond, payment of the redemption price
will be made only upon surrender of this bond in exchange for a
bond or bonds (but only of authorized denominations) for the
unredeemed balance of the principal amount of this bond.

                                10

   The Indenture contains provisions permitting the Company and
the Trustee, with the consent of the holders of not less than
seventy-five per cent in principal amount of the bonds (exclusive
of bonds disqualified by reason of the Company's interest
therein) at the time outstanding, including, if more than one
series of bonds shall be at the time outstanding, not less than
sixty per cent in principal amount of each series affected, to
effect, by an indenture supplemental to the Indenture,
modifications or alterations of the Indenture and of the rights
and obligations of the Company and of the holders of the bonds
and coupons; provided, however, that no such modification or
alteration shall be made without the written approval or consent
of the holder hereof which will (a) extend the maturity of this
bond or reduce the rate or extend the time of payment of interest
hereon or reduce the amount of the principal hereof or reduce any
premium payable on the redemption hereof, (b) permit the creation
of any lien, not otherwise permitted, prior to or on a parity
with the lien of the Indenture, or (c) reduce the percentage of
the principal amount of the bonds upon the approval or consent of
the holders of which modifications or alterations may be made as
aforesaid.

   This bond is transferable by the registered owner hereof in
person or by his attorney duly authorized in writing, at the
corporate trust office of the Trustee in the Borough of
Manhattan, City and State of New York, upon surrender of this
bond for cancellation and upon payment of any taxes or other
governmental charges payable upon such transfer, and thereupon a
new registered bond or bonds of the same series and of a like
aggregate principal amount will be issued to the transferee or
transferees in exchange therefor.

   The Company, the Trustee and any paying agent may deem and
treat the person in whose name this bond is registered as the
absolute owner hereof for the purpose of receiving payments of or
an account of the principal hereof and interest due hereon, and
for all other purposes, whether or not this bond shall be
overdue, and neither the Company, the Trustee nor any paying
agent shall be affected by any notice to the contrary.

   Bonds of this series are issuable only in fully registered
form without coupons in denominations of $100,000 or integral
multiples of $1,000 in excess thereof.  The registered owner of
this bond at his option may surrender the same for cancellation
at said office of the Trustee and receive in exchange therefor
the same aggregate principal amount of registered bonds of the
same series and with the same terms and provisions, including the
same issue date, maturity date, and redemption provisions, if
any, and which bear interest at the same rate, but of other
authorized denominations, upon payment of any taxes or other
governmental charges payable upon

                               41

                                11

such exchange and subject to the terms and conditions set forth
in the Indenture.

   If an event of default as defined in the Indenture shall
occur, the principal of this bond may become or be declared due
and payable before maturity in the manner and with the effect
provided in the Indenture.  The holders, however, of certain
specified percentages of the bonds at the time outstanding,
including in certain cases specified percentages of bonds of
particular series, may in the cases, to the extent and as
provided in the Indenture, waive certain defaults thereunder and
the consequences of such defaults.

   No recourse shall be had for the payment of the principal of
or the interest on this bond, or for any claim based hereon, or
otherwise in respect hereof or of the Indenture, against any
incorporator, shareholder, director or officer, past, present or
future, as such, of the Company or of any predecessor or
successor corporation, either directly or through the Company or
such predecessor or successor corporation, under any constitution
or statute or rule of law, or by the enforcement of any
assessment or penalty, or otherwise, all such liability of
incorporators, shareholders, directors and officers, as such,
being waived and released by the holder and owner hereof by the
acceptance of this bond and as provided in the Indenture.

   The Indenture provides that this bond shall be deemed to be a
contract made under the laws of the State of New York, and for
all purposes shall be construed in accordance with and governed
by the laws of said State.

                           ARTICLE ONE.

           BONDS OF THE MEDIUM TERM NOTE SERIES III AND
               CERTAIN PROVISIONS RELATING THERETO.

   SECTION  1.01.  Certain Terms of Bonds of the Medium Term Note
Series III.  The aggregate principal amount of the Bonds of the
Medium Term Note Series III shall be limited to $75,000,000,
excluding, however, any Bonds of the Medium Term Note Series III
which may be executed, authenticated and delivered in exchange
for or in lieu of or in substitution for other Bonds of such
Series pursuant to the provisions of the Original Indenture or of
this Supplemental Indenture.

   The definitive Bonds of the Medium Term Note Series III shall
be issuable only in fully registered form without coupons in the
denomination of $100,000, or any amount in excess thereof that is
a multiple of  $1,000.  Notwithstanding the provisions of Section
2.05 of the Original Indenture, each Bond of the Medium Term Note
Series III shall be dated as of the date of its authentication,
and shall mature on such date not less than nine months nor more
than thirty years from such date, shall bear interest from such
date, shall bear interest at such rate or rates, which may be
fixed or variable, and have such other terms and conditions not
inconsistent with the Original Indenture as the Board of
Directors of the Company, or any officer of the Company acting
pursuant to authority granted by the Board of Directors may
determine (the execution of any bond of the Medium Term Note
Series III by any authorized officer of the Company being, with
regard to any holder of such bond, conclusive evidence of such
approval).  Interest on Bonds of the Medium Term Note Series III
shall be payable on the dates edstablished on the date of first
authentication of such Bond ("Original Issue Date").  The person
in whose name any Bond of the Medium Term Note Series III is
registered at the close of business on the applicable record date
with respect to any interest payment date shall be entitled to
receive the interest payable thereon on such interest payment
date notwithstanding the cancellation of such Bond upon any
transfer or exchange thereof subsequent to such record date and
prior to such interest payment date, unless the Company shall
default in the payment of the interest due on such interest
payment date, in which case such defaulted interest shall be paid
to the person in whose name such Bond is registered on a
subsequent record date fixed by the Company, which subsequent
record date shall be fifteen (15) days prior to the payment of
such defaulted interest.  Such interest payments shall be made in
such manner and in such places as provided on the Form of Bonds
of the Medium Term Note Series III set forth in this Supplemental
Indenture.  The principal of the Bonds of the Medium Term Note
Series III shall be payable in any coin or currency

                               46


                                16

of the United States of America which at the time of payment is
legal tender for the payment of public and private debts at the
office or agency of the Company in the Borough of Manhattan, City
and State of New York, and interest and premium, if any, on such
Bonds shall be payable in like coin or currency at said office or
agency.

   The definitive Bonds of the Medium Term Note Series III may be
issued in the form of Bonds, engraved, printed or lithographed on
steel engraved borders.

   Upon compliance with the provisions of Section 2.06 of the
Original Indenture and as provided in this Supplemental
Indenture, and upon payment of any taxes or other governmental
charges payable upon such exchange, Bonds of the Medium Term Note
Series III may be exchanged for a new Bond or Bonds of different
authorized denominations of like aggregate principal amount.

   The Trustee hereunder shall, by virtue of its office as such
Trustee, be the registrar and transfer agent of the Company for
the purpose of registering and transferring Bonds of the Medium
Term Note Series III.

   Notwithstanding the provisions of Section 2.11 of the Original
Indenture, no service charge shall be made for any exchange or
transfer of Bonds of the Medium Term Note Series III, but the
Company at its option may require payment of a sum sufficient to
cover any tax or other governmental charge incident thereto.

   SECTION 1.02.  Redemption Provisions for Bonds of the Medium
Term Note Series III.  The Bonds of the Medium Term Note Series
III shall be subject to redemption prior to maturity as a whole
at any time or in part from time to time as the Board of
Directors of the Company, or any officer of the Company acting
pursuant to authority granted by the Board of Directors may
determine, and as set forth on the Form of Bonds of the Medium
Term Note Series III set forth in this Supplemental Indenture.

   The Bonds of the Medium Term Note Series III which are
redeemable on the payment of a Regular Redemption Price as
provided for in this Section 1.02 may be redeemed at such Regular
Redemption Price through the application of cash deposited with
the Trustee pursuant to Section 6.04 of the Original Indenture
upon the taking, purchase or sale of any property subject to the
lien hereof or thereof in the manner set forth in said Section.

   The Bonds of the Medium Term Note Series III are also subject
to redemption through the application of proceeds of the sale or
disposition

                               47


                                 17

substantially as an entirety of the Company's electric properties
at Portland, Oregon, which proceeds are required by the provisions
of Section 7.01 of the Original Indenture to be applied to the
retirement of Bonds, upon payment of the principal amount thereof
together with interest thereon payable to the date of redemption.

   SECTION 1.03.  Notwithstanding the provisions of Section 4.07
of the Original Indenture, the provisions of Sections 4.04, 4.05,
and 4.06 of the Original Indenture shall remain in full force and
effect and shall be performed by the Company so long as any Bonds
of the Medium Term Note Series III remain outstanding.  The Bonds
of the Medium Term Note Series III which are redeemable on the
payment of a Regular Redemption Price as provided for in Section
1.02 of this Supplemental Indenture may be redeemed at such
Regular Redemption Price with moneys remaining in the replacement
fund provided for in said Section 4.04 of the Original Indenture.

   SECTION 1.04.  The requirements which are stated in the next
to the last paragraph of Section 1.13 and in Clause (9) of
Paragraph A of Section 3.01 of the Original Indenture to be
applicable so long as any of the Bonds of the 1975 Series are
outstanding shall remain applicable so long as any of the Bonds
of the Medium Term Note Series III are outstanding.

   SECTION 1.05.  Notwithstanding the provisions of Section 2.06
or Section 2.10 of the Original Indenture, the Company shall not
be required (i) to issue, register, discharge from registration,
exchange or transfer any Bond of the Medium Term Note Series III
for a period of fifteen (15) days next preceding any selection by
the Trustee of Bonds of the Medium Term Note Series III to be
redeemed or (ii) to register, discharge from registration,
exchange or transfer any Bond of the Medium Term Note Series III
so selected for redemption in its entirety or (iii) to exchange
or transfer any portion of a Bond of the Medium Term Note Series
III which portion has been so selected for redemption.

   SECTION 1.06.  So long as any Bonds of the Medium Term Note
Series III remain outstanding, all references to the minimum
provision for depreciation in the form of certificate of
available additions set forth in Section 3.03 of the Original
Indenture shall be included in any certificate of available
additions filed with the Trustee, but whenever Bonds of the
Medium Term Note Series III shall no longer be outstanding, all
references to such minimum provisions for depreciation may be
omitted from any such certificate.

   SECTION 1.07.  I.  Each holder of any Bond of the Medium Term

                               48


                                18

Note Series III by acceptance of such Bond shall thereby consent
that, at any time after the requisite consents, if any, of the
holders of Bonds of other series shall have been given as
hereinafter provided, Subsections A and G of Section 1.10 of the
Original Indenture be amended so as to read as follows:

   "A.  The term `bondable public utility property' shall mean
and comprise any tangible property now owned or hereafter
acquired by the Company and subjected to the lien of this
Indenture, which is located in the States of Oregon, Washington,
California, Arizona, New Mexico, Idaho, Montana, Wyoming, Utah
and Nevada and is used or is useful to it in the business of
furnishing or distributing electricity for heat, light or power
or other use, or supplying hot water or steam for heat or power
or steam for other purposes, including, without limiting the
generality of the foregoing, all properties necessary or
appropriate for purchasing, generating, manufacturing, producing,
transmitting, supplying, distributing and/or disposing of
electricity, hot water or steam; provided, however, that the term
`bondable public utility property' shall not be deemed to include
any nonbondable property, as defined in Subsection B of this
Section 1.10, or any excepted property."

   "G.  The term `minimum provision for depreciation' for the
period from March 31, 1945 through December 31, 1966, as applied
to bondable public utility property, whether or not subject to a
prior lien, shall mean $35,023,487.50.

   "The term `minimum provision for depreciation' for any calen-
dar year subsequent to December 31, 1966, as applied to bondable
public utility property, shall mean the greater of (i) an amount
equal to 2% of depreciable bondable public utility property, as
shown by the books of the Company as of January 1 of such year,
with respect to which the Company was as of that date required,
in accordance with sound accounting practice, to make
appropriations to a reserve or reserves for depreciation or
obsolescence, or (ii) the amount actually appropriated by the
Company on its books of account to a reserve or reserves for
depreciation or obsolescence in respect of depreciable bondable
public utility property for such calendar year, in either case
less an amount equal to the aggregate of (a) the amount of any
property additions which during such calendar year were included
in an officers' certificate filed with the Trustee as the basis
for a sinking fund credit pursuant to the provisions of a sinking
fund for Bonds of any series, and (b) 166-2/3% of the principal
amount of Bonds of any series which shall have been delivered to
the Trustee as a credit, or which the Company shall have elected
to apply as a credit, against any sinking fund payment due during
such calendar year for Bonds of any

                               49


                                19

series, or which shall have been redeemed in anticipation of, or
out of moneys paid to the Trustee on account of, any sinking fund
payment due during such calendar year for Bonds of any series. 
Bonds delivered to the Trustee as, or applied as, a credit
against any sinking fund payment and Bonds redeemed in
anticipation of any sinking fund payment, regardless of the time
when they were actually delivered, applied or redeemed, for
purposes of the preceding sentence shall be deemed to have been
delivered, applied or redeemed, as the case may be, on the
sinking fund payment date when such sinking fund payment was due. 
Bonds redeemed out of moneys paid to the Trustee on account of
any sinking fund payment shall, regardless of the date when they
were redeemed, for purposes of the second preceding sentence, be
deemed to have been redeemed on the later of (i) the date on
which such moneys were paid to the Trustee or (ii) the sinking
fund payment date when such sinking fund payment was due.

   "The minimum provision for depreciation for any calendar year
subsequent to December 31, 1966, as applied to bondable public
utility property not subject to a prior lien, shall be determined
as set forth in the paragraph immediately preceding, except that
all references therein to `depreciable bondable public utility
property' shall be deemed to be `depreciable bondable public
utility property not subject to a prior lien'.

   "The minimum provision for depreciation as applied to bondable
public utility property and the minimum provision for deprecia-
tion as applied to bondable public utility property not subject
to a prior lien for any period commencing subsequent to December
31, 1966 which is of twelve whole calendar months' duration but
is other than a calendar year or which is of less than twelve
whole calendar months' duration shall be determined by
multiplying the number of whole calendar months in such period by
one-twelfth of the corresponding minimum provision for
depreciation for the most recent calendar year completed prior to
the end of such period, and fractions of a calendar month shall
be disregarded.

   "The aggregate amount of the minimum provision for deprecia-
tion as applied to bondable public utility property and the
aggregate amount of the minimum provision for depreciation as
applied to bondable public utility property not subject to a
prior lien from March 31, 1945 to any date shall be the sum of
the corresponding minimum provision for depreciation for each
completed calendar year between December 31, 1966 and such date,
plus the corresponding minimum provision for depreciation for the
period, if any, from the end of the most recent such completed
calendar year to such date, in each case determined as set forth
above, plus $35,023,487.50.

   "All Bonds credited against any sinking fund payment due sub-
sequent

                               50


                                20

to December 31, 1966 for Bonds of any series and (except as
provided in Section 9.04 with respect to Bonds on which a
notation of partial payment shall be made) all Bonds redeemed in
anticipation of or out of moneys paid to the Trustee as a part of
any sinking fund payment due subsequent to December 31, 1966 for
Bonds of any series, shall be canceled and no such Bonds, nor any
property additions which, subsequent to December 31, 1966, shall
have been included in an officers' certificate filed with the
Trustee as the basis for a sinking fund credit pursuant to the
provisions of a sinking fund for Bonds of any series, shall be
made the basis of the authentication and delivery of Bonds or of
any other further action or credit hereunder."

  II.  Each holder of any Bond of the Medium Term Note Series
III, by acceptance of such Bond shall thereby consent that, at
any time after the requisite consents, if any, of the holders of
Bonds of other series shall have been given as hereinafter

    1.07 provided, be further amended by replacing the word
    "and" between the words "Utah" and "Nevada" with a comma and
    by adding after the word "Nevada" the words "and Alaska";

    (2) Subsection G of Section 1.10 of the Original Indenture,
    as the same may be amended as hereinabove in this Section

    paragraph thereof to read as follows:

       "The term `minimum provision for depreciation' for any
    calendar year subsequent to December 31, 1966, as applied to
    bondable public utility property, shall mean the greater of
    (i) an amount equal to 2% of depreciable bondable public
    utility property, as shown by the books of the Company as of
    January 1 of such year, with respect to which the Company
    was as of that date required, in accordance with sound
    accounting practice, to make appropriations to a reserve or
    reserves for depreciation or obsolescence, or (ii) the
    amount actually appropriated by the Company on its books of
    account to a reserve or reserves for depreciation or
    obsolescence in respect of depreciable bondable public
    utility property for such calendar year, in either case less
    an amount equal to the aggregate of (a) the amount of any
    property additions which during such calendar year were
    included in an officers' certificate filed with the Trustee
    as the basis for a sinking fund credit pursuant to the
    provisions of a sinking fund for Bonds of any series and
    which as a result of having been so included have

    any Bonds of such series are outstanding, to have been
    `included in an officers' certificate filed with the Trustee
    as the basis for a sinking fund credit' and to have been
    `made the basis for action or credit hereunder' as such term
    is defined in Subsection H of Section 1.10 of the Original
    Indenture, and (b) 166-2/3% of the principal amount of Bonds
    of any series which shall have been delivered to the Trustee
    as a credit, or which the Company shall have elected to
    apply as a credit, against any sinking fund payment due
    during such calendar year for Bonds of any series, or which
    shall have been redeemed in anticipation of, or out of
    moneys paid to the Trustee on account of, any sinking fund
    payment due during such calendar year for Bonds of any
    series and which as a result of having been so made the
    basis of a credit upon a sinking fund payment and/or so
    redeemed by operation of a sinking fund shall have been
    disqualified, either without time limit or only so long as
    any Bonds of such series are outstanding, from being made
    the basis of the authentication and delivery of Bonds or of
    any other further action or credit under the Original
    Indenture or any supplemental indenture.  Bonds delivered to
    the Trustee as, or applied as, a credit against any sinking
    fund payment and Bonds redeemed in anticipation of any
    sinking fund payment, regardless of the time when they were
    actually delivered, applied or redeemed, for purposes of the
    preceding sentence shall be deemed to have been delivered,
    applied or redeemed, as the case may be, on the sinking fund
    payment date when such sinking fund payment was due.  Bonds
    redeemed out of moneys paid to the Trustee on account of any
    sinking fund payment shall, regardless of the date when they
    were redeemed, for purposes of the second preceding
    sentence, be deemed to have been redeemed on the later of
    (i) the date on which such moneys were paid to the Trustee
    or (ii) the sinking fund payment date when such sinking fund
    payment was due."

    and the aggregate amount of the minimum provision for
    depreciation as applied to bondable public utility property
    not subject to a prior lien from March 31, 1945 to any date

    sponding minimum provision for depreciation for the period,
    if any, from the end of the most recent such completed
    calendar year to such date, in each case determined as set
    forth above, plus (2) $35,023,487.50, plus (3) an amount
    equal to the aggregate of (a) the amount of any property
    additions which, between December 31, 1966 and such date,
    became property additions of the character described in
    clause (a) of the second paragraph of this Subsection G and
    which, thereafter, also between December 31, 1966 and such
    date, became `available additions' as a result of the fact
    that all Bonds of such series ceased to be outstanding, and
    (b) 166-2/3% of the principal amount of Bonds of any series
    which, between December 31, 1966 and such date, become Bonds
    of the character described in clause (b) of the second

consent of the holders of Bonds of the Medium Term Note Series
III shall be required to permit such amendments to become
effective and in determining whether the holders of not less than

so long as any Bonds of the Medium Term Note Series III are
outstanding.

                         TRUSTEE.

   SECTION 2.01.  The Trustee hereby accepts the trust hereby
created.  The Trustee undertakes, prior to the occurrence of an
event of default and after the curing of all events of default
which may have occurred, to perform such duties and only such
duties as are specifically set forth in the Original Indenture as
heretofore and hereby supplemented and modified, on and subject
to the terms and conditions set forth in the Original Indenture
as so supplemented and modified, and in case of the occurrence of
an event of default (which has not been cured) to exercise such
of the rights and powers vested in it by the Original Indenture
as so supplemented and modified, and to use the same degree of
care and skill in their exercise, as a prudent man would exercise
or use under the circumstances in the conduct of his own affairs.

   The Trustee shall not be responsible in any manner whatsoever
for or in respect of the validity or sufficiency of this
Supplemental Indenture or the Bonds issued hereunder or the due
execution thereof by the Company.  The Trustee shall be under no
obligation or duty with respect to the filing, registration, or
recording of this Supplemental Indenture or the re-filing,
re-registration, or re-recording thereof.  The recitals of fact
contained herein or in the Bonds (other than the Trustee's
authentication certificate) shall be taken as the statements
solely of the Company, and the Trustee assumes no responsibility
for the correctness thereof.

                    MISCELLANEOUS PROVISIONS.

   SECTION 3.01.  Although this Supplemental Indenture, for
convenience and for the purpose of reference, is dated August 1,
1994, the actual date of execution by the Company and by the
Trustee is as indicated by their respective acknowledgments
hereto annexed.

   SECTION 3.02.  This Supplemental Indenture is executed and
shall be construed as an indenture supplemental to the Original
Indenture as heretofore supplemented and modified, and as
supplemented and modified hereby, the Original Indenture as
heretofore supplemented and modified is in all respects ratified
and confirmed, and the Original Indenture as heretofore and
hereby supplemented and modified shall be read, taken and
construed as one and the same instrument.  All terms used in this
Supplemental Indenture shall be taken to have the same meaning as
in the Original Indenture except in cases where the context
clearly indicates otherwise.

   SECTION 3.03.  In case any one or more of the provisions
contained in this Supplemental Indenture or in the Bonds or
coupons shall for any reason be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions of this
Supplemental Indenture, but this Supplemental Indenture shall be
construed as if such invalid or illegal or unenforceable
provision had never been contained herein.

   SECTION 3.04.  This Supplemental Indenture may be executed in
any number of counterparts, and each of such counterparts shall
for all purposes be deemed to be an original, and all such
counterparts, or as many of them as the Company and the Trustee
shall preserve undestroyed, shall together constitute but one and
the same instrument.
