Indenture shall be Bonds of           
Series, designated as “First Mortgage Bonds,     %
Series due           ”
of the Company. The Bonds of           
Series shall be executed, authenticated and delivered in accordance with the
provisions of, and shall in all respects be subject to, all of the terms,
conditions and covenants of the Original Indenture, except insofar as the terms
and provisions of the Original Indenture have been or are amended or modified

Supplemental Indentures or by this           
Supplemental Indenture. Bonds of

and shall be issued as registered Bonds without coupons in denominations of
$1,000 and in any multiple thereof, and shall bear interest, payable on

the payment of said principal when due and payable, at the rate of     %
per annum thereafter until the Company’s obligation with respect to payment of
said principal shall have been discharged as provided in the Indenture;
provided, however, that if Bonds of           
Series shall have been declared due and payable prior to their stated maturity
and such declaration shall have been annulled as provided in the Indenture, the

payable at the office or agency of the
Company in the Borough of Manhattan, The City of New York, and, at the option
of the Company, interest on each said Bond may also be payable at the office of
the Company in Boise, Idaho, in such coin or currency of the United States of
America as at the time of payment shall be legal tender for public and private
debts. The interest on the Bonds of           
Series, whether in temporary or definitive form, shall be payable without
presentation of such Bonds and (subject to the provisions of this Section 1)
only to or upon the written order of the registered holders thereof.

 

Except as provided in the next succeeding sentence of this Section 1,
each Bond of           
Series shall be dated the date of its authentication and interest shall be
payable on the principal represented thereby from the           
or           , as the
case may be, next preceding the date thereof to which interest has been paid,
unless the date thereof is a           
or        to which interest has been paid,
in which case such interest shall be payable from such date or unless such date
is prior to           ,
in which case interest shall be payable from           .
Each Bond of           
Series authenticated between the record date for any interest payment date and
such interest payment date shall be dated the date of its authentication, but
interest shall be payable from such interest payment date; provided, however,
that if the Company shall default in the payment of the interest due on such
interest payment date, any Bond of           
Series so authenticated shall bear interest from the           
or           , as the
case may be, next preceding the date of such Bond, to which interest has been
paid.

 

Interest on any Bond of           
Series shall be paid to the registered holder of such Bond of           
Series, or, notwithstanding the cancellation thereof, the Bond of           
Series in exchange or substitution for which such Bond shall have been issued,
at the close of business on the applicable record date; provided, however, that
if the Company shall default in the payment of the interest due on any interest
payment date on the principal represented by any Bond of           
Series, such defaulted interest shall be paid to the registered holder of such
Bond (or any Bond or Bonds of           
Series issued upon transfer or exchange thereof) on the date of payment of such
defaulted interest or, at the election of the Company, to the person in whose
name such Bond (or any Bond or Bonds of           
Series issued upon transfer or exchange thereof) is registered on a subsequent
record date established by notice given by mail by or on behalf of the Company
to the holders of Bonds of           
Series not less than ten (10) days preceding such subsequent record date. The
term “record date” as used in this Section 1 shall mean, with respect to any
semi-annual interest payment date, the close of business on           
or           , as the
case may be, next preceding such interest payment date or, in the case of
defaulted interest, the close of business on any subsequent record date
established as provided above.

 

The Bonds of           
Series, in definitive form, shall be, at the option of the Company, fully
engraved or shall be lithographed or printed on steel engraved borders or shall
be partially lithographed or printed and partially engraved on steel engraved
borders or shall be printed on safety paper or shall be typewritten.

8[SECTION 1. The           
Series of Bonds to be executed, authenticated and delivered under and secured
by the Indenture shall be Secured Medium-Term Notes, Series     ,
designated as “First Mortgage Bonds, Secured Medium-Term Notes, Series      
” of the Company. The Bonds of           
Series shall be executed, authenticated and delivered in accordance with the
provisions of, and shall in all respects be subject to, all of the terms,
conditions and covenants of the Original Indenture, except insofar as the terms
and provisions of the Original Indenture have been or are amended or modified by
said First through           
Supplemental Indentures or by this           
Supplemental Indenture. Bonds of           
Series shall be issued from time to time in an aggregate principal amount not
to exceed $          ,
and shall be issued as registered Bonds without coupons in the denominations of
$1,000 or in any multiple thereof; each Bond of           
Series shall mature on such date not less than           
nor more than           
from date of issue, shall bear interest at such rate or rates (which may be
either fixed or variable) and have such other terms and provisions not
inconsistent with the Indenture as the Board of Directors may determine in
accordance with a resolution filed with the Corporate Trustee and a written
order referring to this           
Supplemental Indenture; the principal of and interest on each said Bond to be
payable at the office or agency of the Company in the Borough of Manhattan, The
City of New York and, at the option of the Company, interest on each said Bond
may also be payable at the office of the Company in Boise, Idaho, in such coin
or currency of the United States of America as at the time of payment is legal
tender for public and private debts. Interest on Bonds of           
Series which bear interest at a fixed rate shall be payable semiannually on           
and            of each
year, unless otherwise determined by the Board of Directors and set forth in a
resolution filed with the Corporate Trustee referring to this Supplemental
Indenture and at maturity (each an interest payment date). Interest on Bonds of
           Series
which bear interest at a variable rate shall be payable on the dates (each an
interest payment date) set forth in a resolution filed with the Corporate
Trustee referring to this           
Supplemental Indenture.

 

Notwithstanding the foregoing, so long as there is no existing default
in the payment of interest on the Bonds of           
Series, all Bonds of           
Series authenticated by the Corporate Trustee after the Record Date hereinafter
specified for any interest payment date, and prior to such interest payment
date (unless the date of first authentication of Bonds of such designated
interest rate and maturity is after such Record Date), shall be dated the date
of authentication, but shall bear interest from such interest payment date, and
the person in whose name any Bond of           
Series is registered at the close of business on any Record Date with respect
to any interest payment date shall be entitled to receive the interest payable
on such interest payment date, notwithstanding the cancellation of such Bond of
           Series,
upon any transfer or exchange thereof subsequent to the Record Date and on or
prior to such interest payment date. If the date of first authentication of the
Bonds of           
Series of a designated interest rate and maturity is after such Record Date and
prior to the corresponding interest payment date, such Bonds shall bear
interest from the Original Interest Accrual Date but payment of interest shall
commence on the second interest payment date succeeding the Original Interest
Accrual Date. “Record Date” for Bonds of           

 

8               These provisions will be inserted
in lieu of Section 1 above in any supplemental indenture relating to the
issuance of First Mortgage Bonds which are designated “Secured Medium-Term
Notes, Series     ”.

Series which bear interest at a fixed rate that is payable on other dates,
shall mean the last day of the calendar month preceding such interest payment
date if such interest payment date is the fifteenth day of a calendar month and
shall mean the fifteenth day of the calendar month preceding such interest
payment date if such interest payment date is the first day of a calendar
month, unless, in each case, otherwise determined by the Board of Directors and
set forth in a resolution filed with the Corporate Trustee referring to this             
Supplemental Indenture, and for Bonds of           
Series which bear interest at a variable rate, shall mean the date 15 calendar
days prior to any interest payment date, unless otherwise determined by the
Board of Directors and set forth in a resolution filed with the Corporate
Trustee referring to this             
Supplemental Indenture; provided that, interest payable on the maturity date
will be payable to the person to whom the principal thereof shall be payable.
“Original Interest Accrual Date” with respect to Bonds of           
Series of a designated interest rate and maturity shall mean the date of first
authentication of Bonds of such designated interest rate and maturity unless a
written order filed with the Corporate Trustee on or before such date shall
specify another date from which interest shall accrue, in which case “Original
Interest Accrual Date” shall mean such other date specified in the written order
for Bonds of such designated interest rate and maturity.

Series, in definitive form, shall be, at the option of the Company, fully
engraved or shall be lithographed or printed on steel engraved borders or shall
be partially lithographed or printed and partially engraved on steel borders or
shall be printed on safety paper or shall be typewritten.]

Series consent that the Company may, but shall not be obligated to, fix a
record date for the purpose of determining the holders of Bonds of           
Series entitled to consent to any amendment, supplement or waiver. If a record
date is fixed, those persons who are holders at such record date (or their duly
designated proxies), and only those persons, shall be entitled to consent to
such amendment, supplement or waiver or to revoke any consent previously given,
whether or not such persons continue to be holders after such record date. No
such consent shall be valid or effective for more than 90 days after such
record date.

the option of the registered holder, any Bonds of

written instrument of transfer (if so required by the Company or by the
Trustees) in form approved by the Company duly executed by the registered
holder or by his duly authorized attorney, shall be exchangeable for a like
aggregate principal amount and maturity of Bonds of           
Series of other authorized denominations. Bonds of

Board of Directors or the Executive Committee of the Board of Directors of the

may appear on the reverse of such form.

 

SECTION 4.           Until

             SUPPLEMENTAL INDENTURE

 

Dated as of                         

 

TO

 

INDENTURE

 

Dated as of August 1, 2001

 

DEBT SECURITIES

 

 

 

 

 

          
SUPPLEMENTAL INDENTURE dated as of                       
made and entered into by and between IDAHO POWER COMPANY, a corporation of the
State of Idaho (hereinafter, subject to Article XI of the Indenture, called the
“Issuer” or the “Company”), having its principal office at 1221 West Idaho
Street, Boise, Idaho 83702-5627, and DEUTSCHE BANK TRUST COMPANY AMERICAS
(formerly known as Bankers Trust Company), a banking corporation organized and
existing under the laws of the State of New York, as Trustee (hereinafter, subject
to Article VII of the Indenture, called the “Trustee”), having its principal
office at 60 Wall Street, New York, New York 10005, as Trustee under the
Indenture for Debt Securities dated as of August 1, 2001 executed and delivered
by Idaho Power Company.

 

WHEREAS the
Indenture dated as of August 1, 2001 (herein with all indentures supplemental
thereto called the “Indenture”), provides for the issuance of notes, debentures
or other evidences of its indebtedness in one or more series (hereinafter
called the “Securities”), unlimited in aggregate principal amount;

 

WHEREAS the
Indenture provides in Article III thereof that, prior to the issuance of
Securities of any series, the form of such Securities and the terms applicable
to such series shall be established in, or pursuant to, the authority granted
in a resolution of the Board of Directors (delivered to the Trustee in the form
of a Board Resolution) or established in one or more indentures supplemental
thereto;

 

WHEREAS the
Issuer desires by this Supplemental Indenture, among other things, to establish
the form of the Securities of a series of the Issuer, and to establish the
terms applicable to such series, pursuant to Sections 3.1 and 10.1(e) of the
Indenture;

 

WHEREAS the
execution and delivery of this Supplemental Indenture by the parties hereto are
in all respects authorized by the provisions of the Indenture; and

 

WHEREAS all
things necessary have been done to make this Supplemental Indenture a valid
agreement of the Issuer, in accordance with its terms.

 

NOW,
THEREFORE, THIS               
SUPPLEMENTAL INDENTURE WITNESSETH:

 

For and in
consideration of the premises, it is mutually covenanted and agreed, as
follows:

 

2

 

ARTICLE I.

 

                           Notes, Series     

 

SECTION 1.           The
title of the series of the Securities established by this Supplemental
Indenture shall be “                
Notes, Series     , due                     ”
of the Issuer (hereinafter called the “Series     
Notes”).  The Series Notes shall bear
interest (computed on the basis of a 360-day year of twelve 30-day months)
until the principal amount thereof has been duly paid or provided for in full,
at a rate per annum equal to       % and
at the same rate per annum on any overdue principal or (to the extent legally
enforceable) on any overdue installment of interest (the “Overdue Rate”).

 

SECTION 2.           The
Series      Notes shall be limited in aggregate
principal amount to $                        ,
and shall be issued substantially in the form set forth in Exhibit A hereto
(which is hereby incorporated herein and made a part hereof), subject to
changes in the form thereof made by the Issuer and acceptable to the
Trustee.  The Series     
Notes shall mature on                     .

 

Interest shall
be payable [quarterly] in arrears on the           
day of                     ,
                    ,
                  
and             
(each, an “Interest Payment Date”) and at Maturity.  If any Interest Payment Date would otherwise
be a day that is not a Business Day, such Interest Payment Date shall be
postponed to the next day that is a Business Day.  If Maturity would otherwise be a day that is
not a Business Day, the payment of principal and interest due at Maturity shall
be made on the next day that is a Business Day and no interest shall accrue as
a result of such delayed payment.

 

Each payment
of interest with respect of an Interest Payment Date or at Maturity shall
include interest accrued to but excluding such Interest Payment Date or
Maturity, as the case may be (an “Interest Period”).

 

Interest on
any Series      Note that is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be
paid to the person in whose name such Series     
Note is registered at the close of business on the                 
day of the month next preceding such Interest Payment Date (the “Regular Record
Date”).  In the case of any Series     
Note issued between a Regular Record Date and the initial Interest Payment
Date, interest for the period beginning on the date of issue and ending on the
initial Interest Payment Date shall be paid to the person to whom such Series     
Note shall have been originally issued. 
Notwithstanding the foregoing, any interest that is payable but not
punctually paid or duly provided for on any Interest Payment Date shall
forthwith cease to be payable to the registered owner of such Series     
Note on such Regular Record Date, and may be paid to the person in whose name
such Series      Note is registered at the close of
business on the Special Record Date established by the Issuer pursuant to
Section 3.8 of the Indenture or as otherwise provided in Section 3.8 of the
Indenture.

 

Payments of
interest on any Series      Note (other than interest
payable at Maturity) will be made by mailing a check to the Holder at the
address of the Holder appearing on the Securities Register on the applicable
record date, unless otherwise agreed to by the Issuer.

 

3

 

The principal
amount thereof  and any premium and the
interest payable at Maturity will be paid at Maturity against presentation of a
Series      Note at the office or agency of the Issuer
maintained for that purpose in the Borough of Manhattan, The City of New York,
or as otherwise provided in the Indenture.

 

[The Series     
Notes are not redeemable prior to Maturity and the provisions of Article XIV of
the Indenture are inapplicable.]

 

[The Series     
Notes are not entitled to any sinking fund and the provisions of Article XV of
the Indenture are inapplicable thereto.]

 

The Series     
Notes are subject to the provisions of Article XII of the Indenture, which
provide for the satisfaction and discharge of the Indenture under the
circumstances and on the conditions set forth therein.

 

SECTION 3.           The
Series      Notes may be issued in whole or in part
as one or more Global Securities and The Depository Trust Company, or a nominee
thereof, shall be the Depository for such Global Security or Global Securities,
except in each case as otherwise provided in a Company Order with respect to
any Series      Notes.  The Depository for such Global Security or
Global Securities representing Series      Notes may
surrender one or more Global Securities representing Series     
Notes in exchange in whole or in part for individual Series     
Notes on such terms as are acceptable to the Issuer and such Depository and
otherwise subject to the terms of Section 2.4 of the Indenture.

 

SECTION 4.           The
Issuer hereby appoints, or confirms the appointment of, Deutsche Bank Trust
Company Americas as the initial Trustee, Securities Registrar and Paying Agent,
subject to the provisions of the Indenture with respect to resignation, removal
and succession, and subject, further, to the right of the Issuer to appoint
additional agents (including Paying Agents). 
An Authenticating Agent may be appointed for the Series     
Notes under the circumstances set forth in, and subject to the provisions of,
the Indenture.

 

ARTICLE II.

 

Miscellaneous Provisions

 

SECTION 1.           The
recitals contained herein shall be taken as the statements of the Issuer, and
the Trustee assumes no responsibility for the correctness of the same.  The Trustee makes no representation as to the
validity of this supplemental indenture. 
The Indenture, as supplemented by this supplemental indenture, is in all
respects hereby adopted, ratified and confirmed.

 

SECTION 2.           The
titles of the several Articles of this           
Supplemental Indenture shall not be deemed to be any part hereof.

 

SECTION 3.           This
            
Supplemental Indenture may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

WHEREOF, the parties hereto have caused this           
Supplemental Indenture to be duly executed.
