Ladies and Gentlemen:

               Idaho Power Company, an Idaho corporation (the "Company"),
confirms its agreement with each of you with respect to the issue and sale by
the Company of up to $250,000,000 aggregate principal amount of its First
Mortgage Bonds, Secured Medium-Term Notes, Series E, Due from Nine Months to
Thirty Years from Date of Issue (the "Notes"). The Notes will be issued under
the Indenture of Mortgage and Deed of Trust, dated as of October 1, 1937,
between the Company and Deutsche Bank Trust Company Americas (formerly known as
Bankers Trust Company), (the "Trustee") and R.G. Page (Stanley Burg, successor
individual trustee), as trustees, as supplemented and amended by all indentures
supplemental thereto



including the Thirty-seventh Supplemental Indenture relating to the Notes dated
as of April 1, 2003 (the "Supplemental Indenture"). The Indenture of Mortgage
and Deed of Trust as it has been and may be supplemented as of any specified
date is hereinafter referred to as the "Indenture". Unless otherwise
specifically provided for and set forth in a Pricing Supplement (as defined
below), the Notes will be issued in minimum denominations of $1,000 and in
denominations exceeding such amount by integral multiples of $1,000, will be
issued only in fully registered form and will have the interest rates,
maturities and, if applicable, other terms set forth in such Pricing Supplement.
The Notes will be issued, and the terms thereof established, in accordance with
the Indenture and the Medium-Term Notes Administrative Procedures attached
hereto as Exhibit A, as they may be amended from time to time (the "Procedures")
(unless a Terms Agreement (as defined in Section 2(b)) modifies or otherwise
supersedes such Procedures with respect to Notes issued pursuant to such Terms
Agreement). The Procedures may be amended only by written agreement of the
Company and you after notice to the Trustee. For the purposes of this Agreement,
the term "Agent" shall refer to any of you acting solely in the capacity as
agent for the Company pursuant to Section 2(a) and not as principal
(collectively, the "Agents"), the term "Purchaser" shall refer to one of you
acting solely as principal pursuant to Section 2(b) and not as agent, and the
term "you" shall refer to you collectively whether at any time any of you is
acting in both such capacities or in either such capacity. In acting under this
Agreement, in whatever capacity, each of you is acting individually and not
jointly.

               1. Representations and Warranties. The Company represents and
warrants to, and agrees with, you as set forth below in this Section 1. Certain
terms used in this Section 1 are defined in paragraph (e) hereof.

               (a) The Company meets the requirements for use of Form S-3 under
the Securities Act of 1933, as amended (the "Act") and has filed with the
Securities and Exchange Commission (the "Commission") a registration statement
on such Form (File Number 333-103812), including a basic prospectus, which has
become effective, for the registration under the Act of $300,000,000 aggregate
amount of its first mortgage bonds, serial preferred stock, without par value,
and debt securities (the "Securities"), including the Notes. Such registration
statement, as amended at the date of this Agreement, meets the requirements set
forth in Rule 415(a)(1)(ix) or (x) under the Act and complies in all other
material respects with said Rule. The Company has filed or will file with the
Commission pursuant to the applicable paragraph of Rule 424(b) under the Act a
supplement to the form of prospectus included in such registration statement
relating to the Notes and the plan of distribution thereof (the "Prospectus
Supplement"). In connection with the sale of Notes the Company proposes to file
with the Commission pursuant to the applicable paragraph of Rule 424(b) under
the Act further supplements to the Prospectus Supplement (each a "Pricing
Supplement") specifying the interest rates, maturity dates and, if appropriate,
other similar terms of the Notes sold pursuant hereto or the offering thereof.

               (b) (i) As of the Execution Time and on the Effective Date, the
Registration Statement complied and (ii) on each date any supplement to the
Prospectus (as defined herein) relating to the Notes is filed with the
Commission, as of the date of a Terms Agreement and at the date of delivery by
the Company of any Notes sold hereunder (a "Closing Date"), the Prospectus, as
supplemented as of any such time, and the Indenture will comply in all material
respects with the applicable requirements of the Act, the Trust Indenture Act of
1939, as amended (the "Trust Indenture Act") and the Securities Exchange Act of
1934, as amended (the

                                       2


"Exchange Act") and the respective rules thereunder; (iii) as of the Execution
Time and on the Effective Date, the Registration Statement, as amended as of
either such time, did not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements therein not misleading; (iv) on each date any
supplement to the Prospectus relating to the Notes is filed with the Commission,
as of the date of a Terms Agreement and on any Closing Date, the Prospectus, as
supplemented as of any such time, will not contain any untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading; and (v) on any Closing Date no stop order suspending the
effectiveness of the Registration Statement shall be in effect nor shall there
have been instituted or threatened any proceeding for such purpose; provided,
however, that the Company makes no representations or warranties as to (i) that
part of the Registration Statement which shall constitute the Statements of
Eligibility of the Trustees (Forms T-1 and T-2), or amendments thereto, under
the Trust Indenture Act or (ii) the information contained in or omitted from the
Registration Statement or the Prospectus (or any supplement thereto) in reliance
upon and in conformity with information, if any, furnished in writing to the
Company by any of you specifically for inclusion in the Registration Statement
or the Prospectus (or any supplement thereto).

               (c) As of the time any Notes are issued and sold hereunder, the
Indenture will constitute a legal, valid and binding instrument enforceable
against the Company in accordance with its terms and such Notes will have been
duly authorized, executed, authenticated and, when paid for by the purchasers
thereof, will constitute legal, valid and binding obligations of the Company
entitled to the benefits of the Indenture.

               (d) As of the time any Notes are issued and sold, the issue and
sale of the Notes and the compliance by the Company with all of the provisions
of the Notes, the Indenture, and this Agreement, and the consummation of the
transactions herein and therein contemplated will not conflict with or result in
a breach or violation of any of the terms or provisions of, or constitute a
default under, any indenture, mortgage, deed of trust, loan agreement or other
agreement or instrument to which the Company is a party or by which the Company
is bound or to which any of the property or assets of the Company is subject,
nor will such action result in any violation of the provisions of the Restated
Articles of Incorporation or By-laws of the Company or any statute or any order,
rule or regulation of any court or governmental agency or body having
jurisdiction over the Company or any of its properties; and no consent,
approval, authorization, order, registration or qualification of or with any
such court or governmental agency or body is required for the issue and sale of
the Notes or the consummation by the Company of the transactions contemplated by
this Agreement or the Indenture, except such orders as have been issued by the
Idaho Public Utilities Commission (which grants authority to sell the Notes
through March 17, 2005), the Public Utility Commission of Oregon and the Public
Service Commission of Wyoming and are in full force and effect, and such as have
been, or will have been prior to any Closing Date, obtained under the Act and
the Trust Indenture Act and such consents, approvals, authorizations,
registrations or qualifications as may be required under state securities or
Blue Sky laws in connection with the sale and distribution of the Notes by the
Agents.

                                       3


               (e) As of the time any Notes are issued and sold hereunder,
immediately after giving effect to the issuance and sale of any Notes and the
retirement of any First Mortgage Bonds of the Company (including without
limitation the Notes as well as any other First Mortgage Bonds previously issued
by the Company under the Indenture) which are concurrently being retired, the
aggregate principal amount of the First Mortgage Bonds of the Company (including
without limitation the Notes as well as any other First Mortgage Bonds
previously issued by the Company under the Indenture) does not exceed
$900,000,000, or such other maximum amount as the Company may establish pursuant
to Sections 22 and 121 of the Indenture, as supplemented and amended by all
indentures supplemental thereto as of the date thereof.

               (f) The terms which follow, when used in this Agreement, shall
have the meanings indicated. The term "the Effective Date" shall mean each date
that the Registration Statement and any post-effective amendment or amendments
thereto became or become effective and each date after the date hereof on which
the Company's most recent Annual Report on Form 10-K is filed. "Execution Time"
shall mean the date and time that this Agreement is executed and delivered by
the parties hereto. "Basic Prospectus" shall mean the form of basic prospectus
relating to the Securities contained in the Registration Statement at the
Effective Date. "Prospectus" shall mean the Basic Prospectus as supplemented by
the Prospectus Supplement and any applicable Pricing Supplement. "Registration
Statement" shall mean the registration statement referred to in paragraph (a)
above, including incorporated documents, exhibits and financial statements, as
amended at the Execution Time. "Rule 415" and "Rule 424" refer to such rules
under the Act. Any reference herein to the Registration Statement, the Basic
Prospectus, the Prospectus Supplement or the Prospectus shall be deemed to refer
to and include the documents incorporated by reference therein pursuant to Item
12 of Form S-3, which were filed under the Exchange Act on or before the
Effective Date of the Registration Statement or the issue date of the Basic
Prospectus, the Prospectus Supplement or the Prospectus, as the case may be; and
any reference herein to the terms "amend", "amendment" or "supplement" with
respect to the Registration Statement, the Basic Prospectus, the Prospectus
Supplement or the Prospectus shall be deemed to refer to and include the filing
of any document under the Exchange Act after the Effective Date of the
Registration Statement or the issue date of the Basic Prospectus, the Prospectus
Supplement or the Prospectus, as the case may be, deemed to be incorporated
therein by reference.

               2. Appointment of Agents; Solicitation by the Agents of Offers to
Purchase; Sales of Notes to a Purchaser. (a) Subject to the terms and conditions
set forth herein and to the reservation by the Company of the right to sell
Securities directly on its own behalf, the Company hereby authorizes each of the
Agents to act as its agent to solicit offers for the purchase of all or part of
the Notes from the Company.

               On the basis of the representations and warranties, and subject
to the terms and conditions set forth herein, each of the Agents agrees, as
agent of the Company, when requested by the Company to use its reasonable best
efforts to solicit offers to purchase the Notes from the Company upon the terms
and conditions set forth in the Prospectus (and any supplement thereto) and in
the Procedures. Each Agent shall make reasonable efforts to assist the Company
in obtaining performance by each purchaser whose offer to purchase Notes has
been solicited by such Agent and accepted by the Company, but such Agent shall
not, except as otherwise

                                       4


provided in this Agreement, be obligated to disclose the identity of any
purchaser or have any liability to the Company in the event any such purchase is
not consummated for any reason. Except as provided in Section 2(b), under no
circumstances will any Agent be obligated to purchase any Notes for its own
account. It is understood and agreed, however, that if approved by the Company
any Agent may purchase Notes as principal pursuant to Section 2(b).

               Each Agent agrees that in carrying out the transactions
contemplated by the Agreement, it will observe and comply with all securities or
blue sky laws, regulations, rules and ordinances in any jurisdiction in which
the Notes may be offered, sold or delivered applicable to it as Agent hereunder.
Each Agent agrees not to cause any advertisement of the Notes to be published in
any newspaper or periodical or posted in any public place and not to publicly
issue any circular relating to the Notes other than the Prospectus, except in
any case with the prior express consent of the Company.

               The Company reserves the right, in its sole discretion, to
instruct the Agents to suspend at any time, for any period of time or
permanently, the solicitation of offers to purchase Notes. Upon receipt of
instructions from the Company, the Agents will forthwith suspend solicitation of
offers to purchase Notes from the Company until such time as the Company has
advised them that such solicitation may be resumed.

               The Company agrees to pay each Agent a commission, for such
Agent's services in acting as an agent and not for a purchase by such Agent as
principal, on the Closing Date with respect to each sale of Notes by the Company
as a result of a solicitation made by such Agent, in an amount equal to that
percentage specified in Schedule I hereto of the aggregate principal amount of
the Notes sold by the Company. Such commission shall be payable as specified in
the Procedures.

               The Company may from time to time offer Securities or Notes for
sale otherwise than through an Agent and from time to time may appoint
additional agents to sell the Notes; provided, however, that so long as this
Agreement shall be in effect, the Company shall not solicit or accept offers to
purchase Notes through any agent other than an Agent, except that the Company
may accept offers to purchase Notes through an agent other than an Agent if the
Company gives the Agents reasonable prior notice of such acceptance and any such
agent enters into an agreement with the Company on terms which are substantially
similar to those contained in or incorporated in this Agreement.

               If the Company shall default in its obligations to deliver Notes
to a purchaser whose offer it has accepted, the Company shall indemnify and hold
each of you harmless against any loss, claim or damage arising from or as a
result of such default by the Company.

               (b) Subject to the terms and conditions stated herein, whenever
the Company and any of you determine that the Company shall sell Notes directly
to any of you as principal, each such sale of Notes shall be made in accordance
with the terms of this Agreement and a supplemental agreement relating to such
sale. Each such supplemental agreement is herein referred to as a "Terms
Agreement". Each Terms Agreement shall describe the Notes to be purchased by the
Purchaser pursuant thereto and shall specify the aggregate principal amount of
such Notes, the price to be paid to the Company for such Notes, the maturity
date of such Notes,

                                       5


the rate at which interest will be paid on such Notes, the dates on which
interest will be paid on such Notes and the record date with respect to each
such payment of interest, the Closing Date for the purchase of such Notes, the
place of delivery of the Notes and payment therefor, the method of payment and
any requirements for the delivery of opinions of counsel, certificates from the
Company or its officers or a letter from the Company's independent public
accountants as described in Section 6(b). Any such Terms Agreement may also
specify the period of time referred to in Section 4(1) and certain terms of the
reoffering of the Notes. Any Terms Agreement shall be substantially in the form
attached hereto as Exhibit B and may take the form of an exchange of any
standard form of written telecommunication between the Purchaser and the
Company. The Purchaser's commitment to purchase Notes shall be deemed to have
been made on the basis of the representations and warranties of the Company
herein contained and shall be subject to the terms and conditions herein set
forth.

               Delivery of the certificates for Notes sold to the Purchaser
pursuant to a Terms Agreement shall be made not later than the Closing Date
agreed to in such Terms Agreement, against payment of funds to the Company in
the net amount due to the Company for such Notes by the method and in the form
set forth in the Procedures unless otherwise agreed to between the Company and
the Purchaser in such Terms Agreement.

               Unless otherwise agreed to between the Company and the Purchaser
in a Terms Agreement, any Note sold to a Purchaser (i) shall be purchased by
such Purchaser at a price equal to 100% of the principal amount thereof less a
percentage equal to the commission applicable to an agency sale of a Note of
identical maturity and (ii) may be resold by such Purchaser at varying prices
related to prevailing market prices determined at the time of resale or, if set
forth in the applicable Terms Agreement and Pricing Supplement, at a fixed
public offering price. In connection with any resale of Notes purchased, a
Purchaser may use a selling or dealer group and may reallow to any broker or
dealer any portion of the discount or commission payable pursuant hereto. Any
resale at a discount may not exceed the amount set forth in the Pricing
Supplement relating to such Notes.

               3. Offering and Sale of Notes. Each Agent and the Company agree
to perform the respective duties and obligations specifically provided to be
performed by them in the Procedures.

               4. Agreements. The Company agrees with you that:

               (a) Prior to the termination of the offering of the Notes
(including by way of resale by a Purchaser of Notes), the Company will not file
any amendment to the Registration Statement or supplement to the Prospectus
(except for (i) periodic or current reports filed under the Exchange Act, (ii) a
supplement relating to any offering of Notes providing solely for the
specification of or a change in the maturity dates, interest rates, issuance
prices or other similar terms of any Notes or (iii) an amendment or a supplement
relating to an offering of Securities other than the Notes) unless the Company
has furnished each of you through your counsel a copy for your review prior to
filing and given each of you a reasonable opportunity to comment on any such
proposed amendment or supplement. Subject to the foregoing sentence, the Company
will cause each supplement to the Prospectus to be filed with the Commission
pursuant to the applicable paragraph of Rule 424(b) within the time period
prescribed and will provide evidence

                                       6


satisfactory to you of such filing. The Company will promptly advise each of you
(i) when the Prospectus, and any supplement thereto, shall have been filed with
the Commission pursuant to Rule 424(b), (ii) when, prior to termination of any
offering of Notes, any amendment of the Registration Statement (except periodic
or current reports filed under the Exchange Act) shall have been filed or become
effective, (iii) of any request by the Commission for any amendment of the
Registration Statement or supplement to the Prospectus or for any additional
information, (iv) of the issuance by the Commission of any stop order suspending
the effectiveness of the Registration Statement or the institution or
threatening of any proceeding for that purpose and (v) of the receipt by the
Company of any notification with respect to the suspension of the qualification
of the Notes for sale in any jurisdiction or the initiation or threatening of
any proceeding for such purpose. The Company will use its best efforts to
prevent the issuance of any such stop order and, if issued, to obtain as soon as
possible the withdrawal thereof.

               (b) If, at any time when a prospectus relating to the Notes is
required to be delivered under the Act, any event occurs as a result of which
the Prospectus as then supplemented would include any untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or if it shall be necessary to amend the Registration
Statement or to supplement the Prospectus to comply with the Act or the Exchange
Act or the respective rules thereunder, the Company promptly will (i) notify
each of you to suspend solicitation of offers to purchase Notes (and, if so
notified by the Company, each of you shall forthwith suspend such solicitation
and cease using the Prospectus as then supplemented), (ii) prepare and file with
the Commission, subject to the first sentence of paragraph (a) of this Section
4, an amendment or supplement which will correct such statement or omission or
effect such compliance and (iii) supply any supplemented Prospectus to each of
you in such quantities as you may reasonably request. If such amendment or
supplement is satisfactory in all respects to you, you will, upon the filing of
such amendment or supplement with the Commission and upon the effectiveness of
an amendment to the Registration Statement, if such an amendment is required,
resume your obligation to solicit offers to purchase Notes hereunder.

               (c) The Company, during the period when a prospectus relating to
the Notes is required to be delivered under the Act, will file promptly all
documents required to be filed with the Commission pursuant to Section 13(a),
13(c), 14 or 15(d) of the Exchange Act and will furnish to each of you copies of
such documents.

               (d) As soon as practicable, the Company will make generally
available to its security holders and to each of you an earnings statement or
statements of the Company and its subsidiaries which will satisfy the provisions
of Section 11(a) of the Act and Rule 158 under the Act.

               (e) The Company will furnish to each of you and your counsel,
without charge, copies of the Registration Statement (including exhibits
thereto), each amendment or supplement to the Indenture entered into subsequent
to the date hereof, and, so long as delivery of a prospectus may be required by
the Act, as many copies of the Prospectus and any supplement thereto as you may
reasonably request.

                                       7


               (f) The Company will use its best efforts to arrange for the
qualification of the Notes for sale under the laws of such jurisdictions as any
of you may reasonably designate, will maintain such qualifications in effect so
long as required for the distribution of the Notes, except that the Company
shall not be required to qualify as a foreign corporation or dealer in
securities or to execute a general consent to service of process in any
jurisdiction.

               (g) The Company shall, whether or not any sale of the Notes is
consummated, (i) pay all expenses incident to the performance of its obligations
under this Agreement and any Terms Agreement, including the fees and
disbursements of its accountants and counsel, the cost of printing or other
production and delivery of the Registration Statement, the Prospectus, all
amendments thereof and supplements thereto, the Supplemental Indenture, this
Agreement, any Terms Agreement and all other documents relating to the offering,
the cost of preparing, printing, packaging and delivering the Notes, the fees
and disbursements of your counsel incurred in compliance with Section 4(f) (such
fees not to exceed $10,000), the fees and disbursements of the Trustee and the
fees of any agency that rates the Notes, (ii) reimburse each of you as requested
for all out-of-pocket expenses (including pre-approved advertising expenses), if
any, incurred by you in connection with the implementation of this program and
(iii) pay the reasonable fees and expenses of your counsel incurred in
connection with the implementation of this program.

               (h) Each acceptance by the Company of an offer to purchase Notes
will be deemed to be an affirmation that its representations and warranties
contained in this Agreement are true and correct at the time of such acceptance,
as though made at and as of such time, and a covenant that such representations
and warranties will be true and correct at the Closing Date relating to such
acceptance, as though made at and as of such time (it being understood that for
purposes of the foregoing affirmation and covenant such representations and
warranties shall relate to the Registration Statement and Prospectus as amended
or supplemented at each such time). Each such acceptance by the Company of an
offer for the purchase of Notes shall be deemed to constitute an additional
representation, warranty and agreement by the Company that, as of the Closing
Date for the sale of such Notes, after giving effect to the issuance of such
Notes, of any other Notes to be issued on or prior to such Closing Date and of
any other Securities to be issued and sold by the Company on or prior to such
Closing Date, the aggregate amount of Securities (including any Notes) which
have been issued and sold by the Company will not exceed the amount of
Securities registered pursuant to the Registration Statement. The Company will
inform you promptly upon your request of the aggregate amount of Securities
registered under the Registration Statement which remain unsold.

               (i) Each time the Company files with the Commission an Annual
Report on Form 10-K or a Quarterly Report on Form 10-Q or a material amendment
or supplement thereto, each time that the Company requests you to solicit offers
to purchase Notes and each time that a Terms Agreement is executed and
delivered, the Company will deliver or cause to be delivered promptly to each of
you a certificate of the Company, in form reasonably satisfactory to you, signed
by the Chief Executive Officer or the President or the principal financial or
accounting officer of the Company, dated the date of delivery of such
certificate, of the same tenor as the certificate referred to in Section 5(d)
but modified to relate to the Registration Statement and the Prospectus as
amended or supplemented at the time of delivery of such certificate; provided
that no such certificate shall be required to be delivered if, since the date of
the certificate most

                                       8


recently theretofore delivered to you pursuant to Section 5(d), 6(b) or this
Section 4(i), either (a) there has been no amendment or supplement to the
Registration Statement or the Prospectus or (b) any amendments or supplements to
the Registration Statement or Prospectus are (i) filed solely to insert a
description of any Securities other than Notes, (ii) filed solely to specify or
change the maturity dates, interest rates, issuance prices or other terms of any
Notes theretofore sold or to change the principal amount of Securities remaining
to be sold or (iii) in the form of a Current Report on Form 8-K filed with the
Commission solely for the purpose of adding exhibits pursuant to Item 601 of
Regulation S-K.

               (j) Each time the Company files with the Commission an Annual
Report on Form 10-K or a Quarterly Report on Form 10-Q or a material amendment
or supplement thereto, each time that the Company requests you to solicit offers
to purchase Notes and each time that a Terms Agreement is executed and
delivered, the Company will furnish or cause to be furnished promptly to each of
you a written opinion of counsel for the Company, in form reasonably
satisfactory to you, dated the date of delivery of such opinion, of the same
tenor as the opinion referred to in Section 5(b) but modified to relate to the
Registration Statement and the Prospectus as amended or supplemented at the time
of delivery of such opinion; provided that no such opinion shall be required to
be delivered if, since the date of the opinion most recently theretofore
delivered to you pursuant to Section 5(b), 6(b) or this Section 4(j), either (a)
there has been no amendment or supplement to the Registration Statement or the
Prospectus or (b) any amendments or supplements to the Registration Statement or
the Prospectus are (i) filed solely to insert a description of any Securities
other than Notes, (ii) filed solely to specify or change the maturity dates,
interest rates, issuance prices or other terms of any Notes theretofore sold or
to change the principal amount of Securities remaining to be sold or (iii) in
the form of a Current Report on Form 8-K filed with the Commission solely for
the purpose of adding exhibits pursuant to Item 601 of Regulation S-K.

               (k) Each time the Company files with the Commission an Annual
Report on Form 10-K or a Quarterly Report on Form 10-Q or a material amendment
or supplement thereto, each time that the Company requests you to solicit offers
to purchase Notes and each time that a Terms Agreement is executed and
delivered, the Company will cause its independent public accountants to furnish
promptly to each of you a letter, in form reasonably satisfactory to you, dated
the date of delivery of such letter, of the same tenor as the letter referred to
in Section 5(e) but modified to relate to the Registration Statement and the
Prospectus as amended or supplemented at the time of delivery of such letter,
with such changes as may be necessary to reflect changes in the financial
statements and other information derived from the accounting records of the
Company; provided that if the Prospectus or Registration Statement is amended or
supplemented solely to include or incorporate by reference financial information
as of and for a fiscal quarter, the Company's independent public accountants may
limit the scope of such letter, which shall be satisfactory in form to each of
you, to the unaudited financial statements, the related "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and any other
information of an accounting, financial or statistical nature included in such
amendment or supplement, unless, in the reasonable judgment of any of you, such
letter should cover other information or changes in specified financial
statement line items.

               (l) During the period, if any, specified in any Terms Agreement,
the Company shall not, without the prior consent of the Purchaser thereunder,
offer, sell or contract

                                       9


to sell, or otherwise dispose of, directly or indirectly, or announce the
offering of, any first mortgage bonds issued by the Company (other than the
Notes being sold pursuant to such Terms Agreement).

               (m) Notwithstanding the foregoing, it is agreed that if, at any
time and from time to time during the term of this Agreement, the Company should
deliver to the Agents notification of its decision to suspend any sale of Notes
hereunder, then during the period of any such suspension or suspensions the
Company shall be relieved of its obligation to provide to the Agents the
certificate, opinions and letter required pursuant to Sections 4(i), 4(j) and
4(k) hereof. However, whenever such a suspension is lifted, the Company shall be
required to deliver to the Agents, prior to the resumption of any sale of Notes
hereunder, the most recent certificate, opinions and letter which would have
been required except for the suspension.

               (n) During the term of this Agreement, the Company shall furnish
to each Agent (i) copies of all annual, quarterly and other reports furnished to
the shareholders of the Company, (ii) copies of all annual, quarterly and
current reports (without exhibits but including documents incorporated therein
by reference) of the Company filed with the Commission under the Exchange Act,
(iii) copies of all announcements made to the general financial community and
(iv) notice of (x) any decrease in the rating or (y) credit watch with negative
implications, in either case of the Notes or any other debt securities of the
Company, by any "nationally recognized statistical rating organization" (as
defined for purposes of Rule 436(g) under the Act).

               (o) The Company agrees that any person who has agreed to purchase
and pay for any Note pursuant to a solicitation by any of the Agents shall have
the right to refuse to purchase such Note if, subsequent to the agreement to
purchase such Note, any change, condition or development specified in any of
Sections 8(b)(iii), (iv) or (v) shall have occurred (with the judgment of the
Agent which presented the offer to purchase such Note being substituted for any
judgment of a Purchaser required therein) the effect of which is, in the
judgment of the Agent which presented the offer to purchase such Note, so
material and adverse as to make it impractical or inadvisable to proceed with
the sale and delivery of such Note (it being understood that under no
circumstance shall any such Agent have any duty or obligation to the Company or
to any such person to exercise the judgment permitted to be exercised under this
Section 4(o)).

               5. Conditions to the Obligations of the Agents. The obligations
of each Agent to solicit offers to purchase the Notes shall be subject to the
accuracy of the representations and warranties on the part of the Company
contained herein as of the Execution Time, on the Effective Date, when any
supplement to the Prospectus relating to the Notes is filed with the Commission
and as of each Closing Date, to the accuracy of the statements of the Company
made in any certificates pursuant to the provisions hereof, to the performance
by the Company of its obligations hereunder and to the following additional
conditions:

               (a) If filing of the Prospectus, or any supplement thereto, is
required pursuant to Rule 424(b), the Prospectus, and any such supplement, shall
have been filed in the manner and within the time period required by Rule
424(b); and no stop order suspending the effectiveness of the Registration
Statement shall have been issued and no proceedings for that purpose shall have
been instituted or threatened.

                                       10


               (b) The Company shall have furnished to each Agent the opinions
of LeBoeuf, Lamb, Greene & MacRae, L.L.P., counsel to the Company and Robert W.
Stahman, Esq., General Counsel for the Company, dated the Execution Time
substantially in the forms of Exhibits D and E hereto.

               (c) Each Agent shall have received from Sullivan & Cromwell LLP,
counsel for the Agents, such opinion or opinions, dated the Execution Time, with
respect to the incorporation of the Company, the validity of the Indenture and
the Notes, the Registration Statement, the Prospectus (together with any
supplement thereto) and other related matters as the Agents may reasonably
require, and the Company shall have furnished to such counsel such documents as
they may reasonably request for the purpose of enabling them to pass upon such
matters. In rendering their opinions, Sullivan & Cromwell LLP may rely upon the
opinion described above of Robert W. Stahman, Esq., General Counsel for the
Company, as to all matters of Idaho, Montana, Nevada, Oregon and Wyoming law.

               (d) The Company shall have furnished to each Agent a certificate
of the Company, signed by the Chief Executive Officer or the President or the
principal financial or accounting officer of the Company, dated the Execution
Time, to the effect that:

                    (i) the representations and warranties of the Company in
               this Agreement are true and correct in all material respects on
               and as of the date hereof with the same effect as if made on the
               date hereof and the Company has complied with all the agreements
               and satisfied all the conditions on its part to be performed or
               satisfied as a condition to the obligation of the Agents to
               solicit offers to purchase the Notes;

                    (ii) no stop order suspending the effectiveness of the
               Registration Statement has been issued and no proceedings for
               that purpose have been instituted or, to the Company's knowledge,
               threatened; and

                    (iii) since the date of the most recent audited financial
               statements included in or incorporated by reference in the
               Prospectus, there has been no material adverse change or any
               development that could reasonably be expected to result in a
               material adverse change in the condition (financial or other),
               earnings, business or properties of the Company and its
               subsidiaries considered as a whole, whether or not arising from
               transactions in the ordinary course of business, except as set
               forth in or contemplated by the Prospectus.

               (e) At the Execution Time, Deloitte & Touche shall have furnished
to each Agent a letter or letters (which may refer to letters previously
delivered to the Agents), dated as of the Execution Time to the effect set forth
in Exhibit C hereto.

               (f) Prior to the Execution Time, the Company shall have furnished
to each Agent such further information, documents and certificates as the Agents
may reasonably request.

               If any of the conditions specified in this Section 5 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and

                                       11


certificates mentioned above or elsewhere in this Agreement shall not be in all
material respects reasonably satisfactory in form and substance to such Agents
and counsel for the Agents, this Agreement and all obligations of any Agent
hereunder may be cancelled at any time by the Agents. Notice of such
cancellation shall be given to the Company in writing or by telephone or
telegraph confirmed in writing.

               The documents required to be delivered by this Section 5 shall be
delivered at the office of LeBoeuf, Lamb, Greene & MacRae, L.L.P., counsel for
the Company, on the date hereof.

               6. Conditions to the Obligations of a Purchaser. The obligations
of a Purchaser to purchase any Notes will be subject to the accuracy of the
representations and warranties on the part of the Company herein as of the date
of the related Terms Agreement and as of the Closing Date for such Notes, to the
performance and observance by the Company of all covenants and agreements herein
contained on its part to be performed and observed and to the following
additional conditions precedent:

               (a) No stop order suspending the effectiveness of the

               (b) To the extent agreed to between the Company and the Purchaser

set forth in Section 5(d) (except that references to the Prospectus shall be to
the Prospectus as supplemented as of the date of such Terms Agreement), (ii) the
opinions of LeBoeuf, Lamb, Greene & MacRae, L.L.P., and Robert W. Stahman, Esq.,
counsel for the Company, dated as of the Closing Date, to the effect referred to

               (c) Prior to the Closing Date, the Company shall have furnished
to the Purchaser such further information, certificates and documents as the
Purchaser may reasonably request.

               If any of the conditions specified in this Section 6 shall not
have been fulfilled in all material respects when and as provided in this
Agreement and the applicable Terms Agreement, or if any of the opinions and
certificates mentioned above or elsewhere in this Agreement or such Terms
Agreement and required to be delivered to the Purchaser pursuant to the terms
hereof and thereof shall not be in all material respects reasonably satisfactory
in form and substance to the Purchaser and its counsel, such Terms Agreement and
all obligations of the Purchaser thereunder and with respect to the Notes
subject thereto may be cancelled at, or at any time prior to, the respective
Closing Date by the Purchaser. Notice of such cancellation shall be given to the
Company in writing or by telephone or telegraph confirmed in writing.

                                       12


               7. Indemnification. (a) The Company will indemnify and hold
harmless each of you against any losses, claims, damages or liabilities, joint
or several, to which you may become subject, under the Act or otherwise, insofar
as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement
of any material fact contained in any preliminary prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus, or any
amendment or supplement thereto, and any other prospectus relating to the Notes,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading; and will reimburse each of you for any legal
or other expenses reasonably incurred by you in connection with investigating or
defending against such loss, claim, damage, liability or action as such expenses
are incurred; provided, however, that the Company shall not be liable in any
such case to the extent that any such loss, claim, damage or liability arises
out of or is based upon an untrue statement or alleged untrue statement or
omission or alleged omission made in any preliminary prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus, or such
amendment or supplement and any other prospectus relating to the Notes, in
reliance upon and in conformity with information furnished in writing to the
Company by you or on your behalf for inclusion therein or arising out of, or
based upon, statements in or omissions from Exhibits 25.1 and 25.3 to the
Registration Statement which shall constitute the Statements of Eligibility of
the Trustees on Forms T-1 and T-2, or amendments thereto, under the Indenture
and provided further that the Company shall not be liable to any of you under
the indemnity agreement in this subsection on account of any such loss, claim,
damage or liability of yours arising from the sale of the Notes to any person,
if at or prior to the written confirmation of such sale a copy of the Prospectus
(exclusive of the documents incorporated by reference therein), or of the
Prospectus as then amended or supplemented (exclusive of the documents
incorporated by reference therein) shall not have been given or sent to such
person by you or on your behalf. This indemnity agreement shall be in addition
to any liability which the Company may otherwise have.

               The foregoing indemnity agreement shall, upon the same terms and
conditions, extend to and inure to the benefit of each person, if any, who
controls any of you within the meaning of the Act.

               (b) Each of you severally and not jointly will indemnify and hold
harmless the Company against any losses, claims, damages or liabilities to which
the Company may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any preliminary prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus, or any
amendment or supplement thereto, and any other prospectus relating to the Notes,
or arise out of or are based upon the omission or the alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in a preliminary prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus, or such
amendment or supplement, and any other Prospectus relating to the Notes, in
reliance upon and in conformity with information furnished in writing to the
Company by you or on your behalf for inclusion therein; and will reimburse the
Company for any legal or other expenses reasonably incurred by the Company in
connection

                                       13


with investigating or defending against any such loss, claim, damage, liability
or action as such expenses are incurred. This indemnity agreement shall be in
addition to any liability which you may otherwise have.

               The foregoing indemnity agreement shall, upon the same terms and
conditions, extend to and inure to the benefit of each director of the Company,
each of its officers who has signed the Registration Statement and each person,
if any, who controls the Company within the meaning of the Act.

               (c) Promptly after receipt by an indemnified party under
subsection (a) or (b) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. In case any such
action shall be brought against any indemnified party, and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate in, and, to the extent that it shall wish, jointly with
any other indemnifying party similarly notified, to assume the defense thereof,
with counsel satisfactory to such indemnified party (who shall not, except with
the consent of the indemnified party, be counsel to the indemnifying party), and
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation.

               (d) If the indemnification provided for in this Section 7 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and each of you on the
other from the offering of the Notes to which such loss, claim, damage or
liability (or actions in respect thereof) relates and also the relative fault of
the Company on the one hand and each of you on the other in connection with the
statements or omissions which resulted in such losses, claims, damages or
liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative benefits received by the Company on the
one hand and each of you on the other shall be deemed to be in the same
proportion as the total net proceeds from such offering (before deducting
expenses) received by the Company bear to the total discounts and commissions
received by you. The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company on the one hand or any of you on the other
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
each of you agree that it would not be just and equitable if contribution
pursuant to this subsection (d) were determined by pro rata allocation or by any
other method of allocation which does not take account of the equitable
considerations referred to above in this subsection (d). The amount paid or
payable by an indemnified party as

                                       14


a result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to above in this subsection (d) shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this subsection (d), you shall not be required
to contribute any amount in excess of the amount by which the total price at
which the Notes sold by or through you to the public exceeds the amount of any
damages which you have otherwise been required to pay by reason of such untrue
or alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The obligations of each of you in this subsection
(d) to contribute are several in proportion to the respective purchases made by
or through you to which such loss, claim, damage or liability (or action in
respect thereof) relates and are not joint.

               8. Termination. (a) This Agreement will continue in effect until
terminated as provided in this Section 8. This Agreement may be terminated
either by the Company as to any Agent or by any of you insofar as this Agreement
relates to any Agent, by giving written notice of such termination to such Agent
or the Company, as the case may be. This Agreement shall so terminate at the
close of business on the first business day following the receipt of such notice
by the party to whom such notice is given. In the event of such termination, no
party shall have any liability to the other party hereto, except as provided in
the fifth paragraph of Section 2(a), Section 4(g), Section 7 and Section 9.

               (b) Each Terms Agreement shall be subject to termination in the
absolute discretion of the Purchaser, by written notice given to the Company
prior to delivery of any payment for any Note to be purchased thereunder, if
subsequent to the agreement to purchase such Note and prior to such payment time
(i) there shall have occurred any change in or affecting the business or
properties of the Company and its subsidiaries taken as a whole the effect of
which is, in the judgment of the Purchaser, so material and adverse as to make
it impracticable or inadvisable to enforce contracts for the sale of such Note,
(ii) there shall have been any decrease in the rating of any of the Company's
first mortgage bonds by Moody's Investors Service Inc. or Standard & Poor's
Corporation the effect of which is, in the judgment of the Purchaser, so
material and adverse as to make it impracticable or inadvisable to enforce
contracts for the sale of such Notes, (iii) trading in securities generally on
the New York Stock Exchange shall have been suspended or limited or minimum
prices shall have been established on such Exchange, (iv) a general moratorium
on commercial banking activities shall have been declared by either Federal or
New York State authorities or a material disruption in commercial banking or
securities settlement or clearance services in the United States shall have
occurred, (v) there shall have occurred any outbreak or escalation of
hostilities, declaration by the United States of a national emergency or war or
other calamity or crisis the effect of which is such as to make it, in the
judgment of the Purchaser, impracticable or inadvisable to proceed with the
public offering or the delivery of the Notes on the terms and in the manner
contemplated in the Prospectus or (vi) there shall have occurred any adverse
change in national or international financial, political or economic conditions
the effect of which is such as to make it, in the judgment of the Purchaser,
impracticable or inadvisable to proceed with the public offering or the delivery
of the Notes on the terms and in the manner contemplated in the Prospectus.

                                       15


               9. Survival of Certain Provisions. The respective
representations, warranties, indemnities and other statements of the Company or
its officers and of you set forth in or made pursuant to this Agreement will
remain in full force and effect, regardless of any investigation made by or on
behalf of you or the Company or any of the persons referred to in Section 7
hereof, and will survive delivery of and payment for the Notes. The provisions
of Sections 4(g) and 7 hereof shall survive the termination or cancellation of
this Agreement. The provisions of this Agreement applicable to any purchase of a
Note for which an agreement to purchase exists prior to the termination hereof
shall survive any termination of this Agreement. If at the time of termination
of this Agreement any Purchaser shall own any Notes with the intention of
selling them, the provisions of Section 4 shall remain in effect until such
Notes are sold by the Purchaser.

               10. Notices. All communications hereunder will be in writing and
effective only on receipt, and, if sent to any of you, will be mailed, delivered
or telegraphed and confirmed to such of you, at the address specified in
Schedule I hereto; or, if sent to the Company, will be mailed, delivered or
telegraphed and confirmed to it at 1221 W. Idaho Street, Boise, Idaho
83702-5627, attention of the Secretary.

               11. Successors. This Agreement will inure to the benefit of and
be binding upon the parties hereto, their respective successors, the controlling
persons referred to in Section 7 hereof and no other person will have any right
or obligation hereunder.

               12. Applicable Law. This Agreement will be governed by and
construed in accordance with the laws of the State of New York.

               13. Counterparts. This Agreement may be executed by any one or
more of the parties hereto and thereto in any number of counterparts, each of
which shall be deemed to be an original, but all such respective counterparts
shall together constitute one and the same instrument.

                                       16


               If the foregoing is in accordance with your understanding of our

                                 Book-Entry Form

               The First Mortgage Bonds, Secured Medium-Term Notes, Series E,
Due from Nine Months to Thirty Years from Date of Issue (the "Notes") of Idaho
Power Company (the "Company") are to be offered on a continuing basis. Banc of
America Securities LLC, Banc One Capital Markets, Inc., McDonald Investments
Inc., U.S. Bancorp Piper Jaffray Inc., Wachovia Securities, Inc. and Wells Fargo
Brokerage Services, LLC, as agents (each an "Agent"), have agreed to use their
reasonable best efforts to solicit purchases of Notes issued in fully registered
form. The Agents will not be obligated to purchase Notes for their own account.
The Notes are being sold pursuant to a Selling Agency Agreement between the
Company and the agents named therein (including the Agents) dated the date
hereof (the "Agency Agreement"). The Notes have been registered with the
Securities and Exchange Commission (the "Commission"). The Notes will be issued
under the Company's Indenture of Mortgage and Deed of Trust, dated as of October
1, 1937, between the Company and Deutsche Bank Trust Company Americas, formerly
known as Bankers Trust Company (the "Trustee") and R.G. Page (Stanley Burg,
successor individual trustee), as trustees, as supplemented, pursuant to the
Thirty-seventh Supplemental Indenture dated as of April 1, 2003 (the
"Indenture").

               The Agency Agreement provides that Notes may also be purchased by
an Agent acting solely as principal and not as agent. In the event of any such
purchase, the functions of both the Agent and the beneficial owner under the
administrative procedures set forth below shall be performed by such Agent
acting solely as principal, unless otherwise agreed to between the Company and
such Agent acting as principal.

               Each Note will be represented by a Global Security (as defined
hereinafter) delivered to Deutsche Bank Trust Company Americas ("Deutsche Bank")
as agent for The Depository Trust Company ("DTC"), and recorded in the
book-entry system maintained by DTC (a "Book-Entry Note"). An owner of a
Book-Entry Note will not be entitled to receive a certificate representing such
Note.

               The procedures to be followed during, and the specific terms of,
the solicitation of orders by the Agents and the sale as a result thereof by the
Company are explained below. Administrative and record-keeping responsibilities
will be handled for the Company by its Finance Department. The Company will
advise the Agents and the Trustee in writing of those persons handling
administrative responsibilities with whom the Agents and the Trustee are to
communicate regarding orders to purchase Notes and the details of their
delivery.

               Administrative procedures and specific terms of the offering are
explained below. Book-Entry Notes will be issued in accordance with the
administrative procedures set forth below, as adjusted in accordance with
changes in DTC's operating requirements. Unless otherwise defined herein, terms
defined in the Indenture and the Notes shall be used herein as

<Page>

therein defined. Only fixed rate Notes may be issued. To the extent the
procedures set forth below conflict with the provisions of the Notes, the
Indenture, DTC's operating requirements or the Agency Agreement, the relevant
provisions of the Notes, the Indenture, DTC's operating requirements and the
Agency Agreement shall control.

                          Administrative Procedures for
                                Book-Entry Notes

               In connection with the qualification of the Book-Entry Notes for

Representations from the Company and Deutsche Bank to DTC dated as of November
21, 2000, a Bring-Down Letter of Representations from the Company and Deutsche
Bank to DTC dated as of April 9, 2003 and a Medium-Term Note Certificate
Agreement between Deutsche Bank and DTC, dated as of October 21, 1988, and its
obligations as a participant in DTC, including DTC's Same-Day Funds Settlement
system ("SDFS").

Issuance:                      On any date of settlement (as defined under
- --------                       "Settlement" below) for one or more Book-Entry
                               Notes, the Company will issue a single global
                               security in fully registered form without coupons

                               $250,000,000 principal amount of all such
                               Book-Entry Notes that have the same Issue Date,
                               original issue discount provisions, if any,

                               authentication by the Trustee. Each Global
                               Security will bear an original issue date, which
                               will be (i) with respect to an original Global
                               Security (or any portion thereof), the original
                               issue date specified in such Global Security and
                               (ii) following a consolidation of Global
                               Securities, with respect to the Global Security
                               resulting from such consolidation, the most

                               has been paid or duly provided for on the
                               predecessor Global Securities, regardless of the
                               date of authentication of such resulting Global
                               Security. No Global Security will represent any
                               securities in certificated form.

Identification Numbers:        The Company has arranged with the CUSIP Service
- ----------------------         Bureau of Standard & Poor's Corporation (the
                               "CUSIP Service Bureau") for the reservation of a
                               series of CUSIP numbers, which series consists of
                               approximately 900 CUSIP numbers and relates to
                               Global Securities representing Book-Entry Notes
                               and book-entry medium-term notes issued by the
                               Company with other series designations. Deutsche
                               Bank, the Company and DTC have obtained from the
                               CUSIP Service Bureau a written list of such
                               reserved CUSIP numbers. Deutsche Bank will assign

                               below under Settlement Procedure "B". DTC will
                               notify the CUSIP Service Bureau periodically of
                               the CUSIP numbers that Deutsche Bank has assigned

                               when fewer than 100 of the reserved CUSIP numbers
                               remain unassigned to Global Securities, and, if
                               it deems necessary, the Company will reserve
                               additional CUSIP numbers for assignment to Global
                               Securities. Upon obtaining such additional CUSIP

                               deliver a list of such additional CUSIP numbers
                               to DTC.

                               Book-Entry Note will be recorded through the
                               records of such Participants or through the

                               behalf of beneficial transferors and transferees
                               of such Note.

                               (ii) a date, occurring at least thirty days after
                               such written notice is delivered and at least

                               number to be assigned to such replacement Global
                               Security. Upon receipt of such a notice, DTC will
                               send to its participants (including Deutsche
                               Bank) a written reorganization notice to the

                               date. Prior to the specified exchange date,
                               Deutsche Bank will deliver to the CUSIP Service
                               Bureau a written reorganization notice setting

                               be valid. On the specified exchange date,
                               Deutsche Bank will exchange such Global
                               Securities for a single Global Security bearing
                               the new CUSIP number and the CUSIP numbers of the

Suspension of Solicitation;    The Company reserves the right, in its sole
Amendment or Supplement:       discretion, to instruct the Agents to suspend at

                               Notes. Upon receipt of such instructions, the
                               Agents will forthwith suspend solicitation until

                               such solicitation may be resumed.

                               In the event that at the time the Company
                               suspends solicitation of purchases there shall be
                               any orders outstanding for settlement, the
                               Company will promptly advise the Agents and
                               Deutsche Bank whether such orders may be settled
                               and whether copies of the Prospectus as in effect
                               at the time of the suspension, together with the
                               appropriate Pricing Supplement, may be delivered
                               in connection with the settlement of such orders.
                               The Company will have the sole responsibility for
                               such decision and for any arrangements that may
                               be made in the event that the Company determines
                               that such orders may not be settled or that
                               copies of such Prospectus may not be so
                               delivered.

                               If the Company decides to amend or supplement the
                               Registration Statement (as defined in the Agency
                               Agreement) or the Prospectus, it will promptly
                               advise the Agents and furnish the Agents with the
                               proposed amendment or supplement and with such
                               certificates and opinions as are required, all to
                               the extent required by and in accordance with the
                               terms of the Agency Agreement. Subject to the
                               provisions of the Agency Agreement, the Company
                               may file with the Commission any such supplement
                               to the Prospectus relating to the Notes. The
                               Company will provide the Agents and Deutsche Bank
                               with copies of any such supplement, and confirm
                               to the Agents that such supplement has been filed
                               with the Commission pursuant to the applicable
                               paragraph of Rule 424(b).

                               At such time as the Company has advised the
                               Agents of the new interest rates, the Agents may
                               resume solicitation of orders. Until such time
                               only "indications of interest" may be recorded.

Delivery of Prospectus:        A copy of the Prospectus (including the

                               written confirmation thereof is sent by the

                               by the Company to a purchaser (other than an

- -----------------              order with respect to a Book-Entry Note pursuant
                               to Settlement Procedure "G", Deutsche Bank may
                               deliver to DTC, through DTC's Participant
                               Terminal System, as soon as practicable, a
                               withdrawal message instructing DTC to debit such
                               Book-Entry Note to Deutsche Bank's participant
                               account. DTC will process the withdrawal message,
                               provided that Deutsche Bank's participant account
                               contains a principal amount of the Global
                               Security representing such Book-Entry Note that

                               debited. If a withdrawal message is processed
                               with respect to all the Book-Entry Notes
                               represented by a Global Security, the Trustee
                               will cancel such Global Security in accordance
                               with the Indenture and so advise the Company and
                               will make appropriate entries in its records. The
                               CUSIP number assigned to such Global Security
                               shall, in accordance with CUSIP Service Bureau
                               procedures, be canceled and not immediately
                               reassigned. If a withdrawal message is processed
                               with respect to one or more, but not all, of the
                               Book-Entry Notes represented by a Global
                               Security, Deutsche Bank will exchange such
                               Book-Entry Note for two Global Securities, one of
                               which shall represent such Book-Entry Notes and
                               shall be cancelled immediately after issuance and
                               the other of which shall represent the other
                               Book-Entry Notes previously represented by the
                               surrendered Global Security and shall bear the
                               CUSIP number of the surrendered Global Security.

                               If the purchase price for any Book-Entry Note is
                               not timely paid to the Participants with respect
                               to such Note by the beneficial purchaser thereof
                               (or a Person, including an indirect participant
                               in DTC, acting on behalf of such purchaser), such
                               Participants and, in turn, the Presenting Agent
                               may enter SDFS deliver orders through DTC's
                               Participant Terminal System reversing the orders
                               entered pursuant to Settlement Procedures "H" and
                               "G", respectively. The Presenting Agent will
                               notify the Company by telephone of such failure.
                               Thereafter, Deutsche Bank will deliver the
                               withdrawal message and take the related actions
                               described in the preceding paragraph.

                               Notwithstanding the foregoing, upon any failure
                               to settle with respect to a Book-Entry Note, DTC
                               may take any actions in accordance with its SDFS
                               operating procedures then in effect. In the event
                               of a failure to settle with respect to one or
                               more, but not all, of the Book-Entry Notes to
                               have been represented by a Global Security,
                               Deutsche Bank will provide, in accordance with
                               Settlement Procedure "E", for the authentication
                               and issuance of a Global Security representing
                               the other Book-Entry Notes to have been
                               represented by such Global Security and will make
                               appropriate entries in its records.

included or incorporated by reference in the Company's Annual Reports on Form
10-K for such fiscal years;

          (iv) On the basis of limited procedures, not constituting an audit in
accordance with generally accepted auditing standards, consisting of a reading
of the unaudited financial statements and other information referred to below, a
reading of the latest available interim financial statements of the Company and
its subsidiaries, inspection of the minute books of the Company and its
subsidiaries since the date of the latest audited financial statements included
or incorporated by reference in the Prospectus, inquiries of officials of the
Company and its subsidiaries responsible for financial and accounting matters
and such other inquiries and procedures as may be specified in such letter,
nothing has come to their attention that caused them to believe that:

                    (A) the unaudited consolidated statements of income,
          consolidated statements of comprehensive income, consolidated balance
          sheets, consolidated statements of cash flows and consolidated
          statements of capitalization included or incorporated by reference in
          the Company's Quarterly Reports on Form 10-Q incorporated by reference
          in the Prospectus do not comply as to form in all material respects
          with the applicable accounting requirements of the Exchange Act as it
          applies to Form 10-Q and the related rules and regulations adopted by
          the SEC;



                    (B) any material modifications should be made to the
          unaudited consolidated financial statements described in (A), included
          or incorporated by reference in the Prospectus, for them to be in
          conformity with generally accepted accounting principles;

                    (C) as of a specified date not more than five days prior to
          the date of such letter, there have been any changes in the
          consolidated capital stock (except for shares of 4% preferred stock)
          or any increase in the consolidated long-term debt of the Company and
          its subsidiaries, or any decreases in consolidated net assets or other
          items specified by the Agents, in each case as compared with amounts
          shown in the latest balance sheet included or incorporated by
          reference in the Prospectus, except in each case for changes,
          increases or decreases which the Prospectus discloses have occurred or
          may occur, for declarations of dividends, or which are described in
          such letter; and

                    (D) for the period from the date of the latest financial
          statements included or incorporated by reference in the Prospectus to
          the specified date referred to in Clause (C) there were any decreases
          in consolidated revenues, net income or earnings on common stock or
          other items specified by the Agents, or any increases in any items
          specified by the Agents, in each case as compared with the comparable
          period of the preceding year and with any other period of
          corresponding length specified by the Agents, except in each case for
          increases or decreases which the Prospectus discloses have occurred or
          may occur, for declarations of dividends, or which are described in
          such letter; and

          (v) In addition to the audit referred to in their report(s) included
or incorporated by reference in the Prospectus and the limited procedures,
inspection of minute books, inquiries and other procedures referred to in
paragraphs (ii) and (iv) above, they have carried out certain specified
procedures, not constituting an audit in accordance with generally accepted
auditing standards, with respect to certain amounts, percentages and financial
information specified by the Agents which are derived from the general
accounting records of the Company and its subsidiaries, which appear in the
Prospectus (excluding documents incorporated by reference), or in Part II of, or
in exhibits and schedules to, the Registration Statement specified by the Agents
or in documents incorporated by reference in the Prospectus specified by the
Agents, and have compared certain of such amounts, percentages and financial
information with the accounting records of the Company and its subsidiaries and
have found them to be in agreement, except as described in such letter.

               All references in this Exhibit C to the Prospectus shall be
deemed to refer to the Prospectus (including the documents incorporated by
reference therein) as amended or supplemented (including the documents
incorporated by reference therein) in relation to the Notes for purposes of the
letter delivered at the Closing Date for such Notes.

To the Agents referred to in the Selling Agency Agreement Relating to:

               $250,000,000 Principal Amount of
               First Mortgage Bonds, Secured Medium-
               Term Notes, Series E, of Idaho Power Company

Ladies and Gentlemen:

               With reference to the issuance and sale by Idaho Power Company,
an Idaho corporation (the "Company"), pursuant to the Selling Agency Agreement,
dated April 15, 2003 (the "Agency Agreement"), between the Company and you of up
to $250,000,000 aggregate principal amount of First Mortgage Bonds, Secured
Medium-Term Notes, Series E (the "Notes"), to be issued under an Indenture of
Mortgage and Deed of Trust, dated as of October 1, 1937, between the Company and
Deutsche Bank Trust Company Americas (formerly known as Bankers Trust Company)
and R.G. Page, as Trustees (Stanley Burg, successor individual trustee) (the
"Trustees"), as supplemented by all indentures supplemental thereto, the latest
such supplemental indenture being the Thirty-seventh Supplemental Indenture,
dated as of April 1, 2003 (said Indenture of Mortgage and Deed of Trust, as so
supplemented, being hereinafter called the "Mortgage"), we advise you that we
are counsel to the Company and in that capacity have reviewed or participated in
the preparation of (1) the Mortgage; (2) the registration statement (File No.
333-103812) relating to the Notes filed with the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as amended (the
"Act") (said registration statement, as amended to the date of effectiveness,
including the documents incorporated by reference therein as of such date
pursuant to Item 12 of Form S-3 (the "Incorporated Documents") being hereinafter
called the "Registration Statement"); (3) the prospectus, dated March 24, 2003
(the "Base Prospectus"), as supplemented by a prospectus supplement relating to
the Notes, dated April 15, 2003 (the "Prospectus Supplement") (such prospectus,
as so supplemented, including the incorporated documents, being hereinafter
referred to as the "Prospectus"); (4) the Agency Agreement and (5) the Bond
Application, dated April 15, 2003 for authentication and delivery of the Notes
in an aggregate principal amount not to exceed $250,000,000 (the "Bond
Application"). Terms not otherwise defined herein shall have the meanings given
to them in the Agency Agreement.

               We have reviewed such corporate records, certificates and other
documents as we have considered necessary or appropriate for purposes of this
opinion.

               Upon the basis of such review, we are of the opinion that:

               (1) The Mortgage has been duly authorized, executed and delivered
by the Company, is a legal, valid and binding instrument enforceable in
accordance with its terms, subject to bankruptcy, insolvency, reorganization or
other laws of general applicability relating to or affecting mortgagees' and
other creditors' rights, and to general principles of equity




(whether considered in a proceeding at law or in equity) and has been qualified
under the Trust Indenture Act of 1939, as amended.

               (2) The Notes, when issued and paid for as contemplated in the
Agency Agreement and in an aggregate principal amount, which, together with all
other first mortgage bonds issued and then outstanding under the Mortgage, after
giving effect to the issuance and sale of any Notes and the retirement of any
first mortgage bonds of the Company (including without limitation the Notes as
well as any other first mortgage bonds previously issued by the Company under
the Mortgage) that are concurrently being retired, does not exceed $900,000,000
or such other maximum amount as the Company may establish pursuant to Section 22
and 121 of the Mortgage, as supplemented and amended by all indentures
supplemental thereto as of the date of the issuance of the Notes, will be legal,
valid and binding obligations of the Company enforceable in accordance with
their terms and entitled to the benefit of the security provided by the
Mortgage, subject to bankruptcy, insolvency, reorganization or other laws of
general applicability relating to or affecting mortgagees' and other creditors'
rights and to general principles of equity (whether considered in a proceeding
at law or in equity).

               (3) The Agency Agreement has been duly authorized, executed and
delivered by the Company.

               (4) The Registration Statement, as of its effective date, and the
Base Prospectus, as supplemented by the Prospectus Supplement, as of the date of
the Prospectus Supplement, complied as to form in all material respects with the
applicable requirements of the Act and the Securities Exchange Act of 1934, as
amended, and the applicable instructions, rules and regulations of the
Commission thereunder; the Registration Statement is effective under the Act;
and, to the best of our knowledge, no proceedings for a stop order with respect
thereto are pending or threatened under Section 8(d) of the Act.

               (5) All regulatory consents and approvals required to be obtained
by the Company from any governmental body or bodies in connection with the
Company's issuance and sale of the Notes in the manner set forth in the Agency
Agreement have been obtained and are in effect, except that the order of the
Idaho Public Utilities Commission grants authority to sell the Notes through
March 17, 2005; it being understood that we express no opinion as to any
consents or approvals required to be obtained, or other actions required to be
taken, under the securities or blue sky laws of any jurisdiction.

               In passing upon the form of the Registration Statement and the
form of the Base Prospectus, as supplemented by the Prospectus Supplement, we
necessarily assume the correctness and completeness of the representations made
to us and the statements made to us or included in the Registration Statement
and the Base Prospectus, as supplemented by the Prospectus Supplement, by the
Company and take no responsibility therefor. In the course of the preparation by
the Company of the Registration Statement and the Base Prospectus, we had
conferences with certain of its officers and representatives, with other counsel
for the Company and with Deloitte & Touche LLP, the independent certified public
accountants who examined certain of the financial statements included or
incorporated by reference in the Registration Statement. Our examination of the
Registration Statement and the Base Prospectus, as supplemented by the
Prospectus Supplement, and our discussions in the above-mentioned

                                       D-2


conferences did not cause us to believe that, at the effective date, the
Registration Statement contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or that the Base Prospectus, as
supplemented by the Prospectus Supplement, as of the date of the Prospectus
Supplement, contained any untrue statement of a material fact or omitted to
state a material fact necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading. Also,
nothing has come to our attention in the course of our examination of the
Registration Statement or the Prospectus or in our discussions in the
above-mentioned conferences that has caused us to believe that the Prospectus,
as of the date and time of the delivery of this letter, contained any untrue
statement of a material fact or omitted to state a material fact necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading. We do not express any views as to the
financial statements or other financial data contained or incorporated by
reference in the Registration Statement or the Prospectus.

               We express no opinion as to the law of any jurisdiction other
than the law of the State of New York and the federal laws of the United States.
As to all matters of Idaho law and as to the matters set forth in paragraph 5
above, we have relied upon an opinion of even date herewith addressed to you by
Robert W. Stahman, Esq., General Counsel for the Company. We are not passing
upon matters relating to the incorporation of the Company, title to property,
liens, licenses, franchises, water rights or conformity to the laws of the
States of Idaho, Montana, Nevada, Oregon or Wyoming, or upon questions of the
recording of, or the validity or priority of the lien of, the Mortgage.

                                        Very truly yours,



                                        LeBoeuf, Lamb, Greene & MacRae, L.L.P.

To the Agents referred to in the Selling Agency Agreement Relating to:

              $250,000,000 Principal Amount of
              First Mortgage Bonds, Secured Medium-
              Term Notes, Series E, of Idaho Power Company

Ladies and Gentlemen:

               In connection with the issuance and sale pursuant to the Selling
Agency Agreement, dated April 15, 2003 (the "Agency Agreement"), between Idaho
Power Company, an Idaho corporation (the "Company"), and you of up to
$250,000,000 aggregate principal amount of the Company's First Mortgage Bonds,
Secured Medium-Term Notes, Series E (the "Notes"), to be issued under an
Indenture of Mortgage and Deed of Trust, dated as of October 1, 1937, between
the Company and Deutsche Bank Trust Company Americas (formerly known as Bankers
Trust Company) and R.G. Page, as Trustees (Stanley Burg, successor individual
trustee) (the "Trustees"), as supplemented by all indentures supplemental
thereto, the latest such supplemental indenture being the Thirty-seventh
Supplemental Indenture, dated as of April 1, 2003 between the Company and the
Trustees (collectively, the "Mortgage"), I am the Company's General Counsel, and
I am familiar with its legal status and that of its property. I am also familiar
with the registration statement (File No. 333-103812) filed under the Securities
Act of 1933, as amended (the "Act"), with the Securities and Exchange Commission
(such registration statement as amended to the date of effectiveness, including
the documents incorporated by reference therein as of such date pursuant to Item
12 of Form S-3 (the "Incorporated Documents") being hereinafter referred to as
the "Registration Statement"), the prospectus, dated March 24, 2003 (the "Base
Prospectus"), as supplemented by a prospectus supplement relating to the Notes,
dated April 15, 2003 (the "Prospectus Supplement") (such prospectus, as so
supplemented, including the incorporated documents, being hereinafter referred
to as the "Prospectus"), the Agency Agreement and the Bond Application, dated
April 15, 2003 for authentication and delivery of Notes in an aggregate
principal amount not to exceed $250,000,000 (the "Bond Application"). Terms not
otherwise defined herein shall have the meanings given to them in the Agency
Agreement.

               I have made such examination of corporate and other records and
documents and of matters of law as in my opinion are necessary or desirable for
the purpose of this opinion, and based thereon, I am of the opinion that:

               (1) The Company has been duly incorporated and is validly
existing and in good standing under the laws of the State of Idaho, and has full
power and authority to own its properties and conduct its business in all
material respects as described in the Prospectus as amended or supplemented;



               (2) To the best of my knowledge and other than as set forth in
the Prospectus as amended or supplemented, there are no legal or governmental
proceedings pending to which the Company or any of its subsidiaries is a party
or of which any property of the Company or any of its subsidiaries is the
subject which would individually or in the aggregate have a material adverse
effect on the consolidated financial position or results of operations of the
Company and its subsidiaries considered as a whole; and, to the best of my
knowledge, no such proceedings are threatened or contemplated by governmental
authorities or threatened by others;

               (3) The Agency Agreement has been duly authorized, executed and
delivered by the Company;

               (4) The Notes, when issued and paid for as contemplated in the
Agency Agreement and in an aggregate principal amount, which, together with all
other first mortgage bonds issued and then outstanding under the Mortgage, after
giving effect to the issuance and sale of any Notes and the retirement of any
first mortgage bonds of the Company (including without limitation the Notes as
well as any other first mortgage bonds previously issued by the Company under
the Mortgage) that are concurrently being retired, does not exceed $900,000,000
or such other maximum amount as the Company may establish pursuant to Section 22
and 121 of the Mortgage, as supplemented and amended by all indentures
supplemental thereto as of the date of the issuance of the Notes, will be legal,
valid and binding obligations of the Company, enforceable in accordance with
their terms and entitled to the benefit of the security provided by the
Mortgage, subject to bankruptcy, insolvency, reorganization or other laws of
general applicability relating to or affecting mortgagees' and other creditors'
rights and to general principles of equity (whether considered in a proceeding
at law or in equity); and the Notes and the Mortgage conform to the descriptions
thereof in the Prospectus as amended or supplemented;

               (5) The Mortgage has been duly authorized, executed and delivered
by the Company and constitutes a valid lien to the extent that it purports to be
one upon the property described therein as being subject to the lien thereof
(except any which has been duly released from the lien thereof) and is a legal,
valid and binding instrument, enforceable in accordance with its terms, subject
to bankruptcy, insolvency, reorganization or other laws of general applicability
relating to or affecting mortgagees' and other creditors' rights and to general
principles of equity (whether considered in a proceeding at law or in equity);
said Mortgage has been duly recorded and filed in such manner and in such places
as are required by law in order to establish, preserve and protect the lien of
said Mortgage;

               (6) The issue and sale of the Notes in an aggregate principal
amount not to exceed the amount set forth in the Bond Application and in an
aggregate principal amount, which, together with all other first mortgage bonds
issued and then outstanding under the Mortgage, after giving effect to the
issuance and sale of any Notes and the retirement of any first mortgage bonds of
the Company (including without limitation the Notes as well as any other first
mortgage bonds previously issued by the Company under the Mortgage) that are
concurrently being retired, does not exceed $900,000,000 or such other maximum
amount as the Company may establish pursuant to Section 22 and 121 of the
Mortgage, as supplemented and amended by all indentures supplemental thereto as
of the date of the issuance of the Notes, and the compliance by the Company with
all of the provisions of the Notes, the Mortgage and the Agency Agreement with
respect to the Notes and the consummation of the transactions therein

                                      E-2


contemplated will not conflict with or result in a breach or violation of any of
the terms or provisions of, or constitute a default under, any indenture,
mortgage, deed of trust, loan agreement or other agreement or instrument to
which the Company is a party or by which the Company is bound or to which any of
the property or assets of the Company is subject, nor will such actions result
in any violation of the provisions of the Restated Articles of Incorporation, as
amended or By-laws, as amended, of the Company or any statute or any order, rule
or regulation of any court or governmental agency or body having jurisdiction
over the Company or any of its properties;

               (7) The description of the Company's property in the Mortgage is
adequate to constitute the Mortgage a lien thereon. The Company has good and
marketable fee title to all real property upon which the Mortgage purports to
create a lien, except water rights, leases, licenses, franchises, easements and
other interests in real property of a similar nature, as to which it has good
and valid title, in each case free and clear of all liens, charges and
encumbrances other than excepted encumbrances as defined in the Mortgage and the
lien of the Mortgage, subject to minor defects and clouds common to property of
the size and character of that of the Company. Such minor defects and clouds are
in my opinion not important and do not materially interfere with the operations
of the Company or materially detract from the value of its property;

               (8) The Company has such valid franchises, permits, licenses,
easements and consents, free from burdensome restrictions, as are required by
law for the operation of the Company's system and as are required for the
adequate conduct of its business in the territory which it serves;

               (9) The Registration Statement, as of its effective date, and the
Base Prospectus, as supplemented by the Prospectus Supplement, as of the date of
the Prospectus Supplement, complied as to form in all material respects with the
requirements of the Act and the Securities Exchange Act of 1934, as amended, and
the applicable instructions, rules and regulations of the Securities and
Exchange Commission thereunder; the Registration Statement is effective under
the Act; and, to the best of my knowledge, no proceedings for a stop order with
respect thereto are pending or threatened under Section 8(d) of the Act; and

               (10) All regulatory consents and approvals required to be
obtained by the Company from any governmental body or bodies in connection with
the Company's issuance and sale of the Notes in the manner set forth in the
Agency Agreement have been obtained and are in effect, except that the order of
the Idaho Public Utilities Commission grants authority to sell the Notes through
March 17, 2005; it being understood that I express no opinion as to any consents
or approvals required to be obtained, or other actions required to be taken,
under state securities or Blue Sky laws of any jurisdiction.

               I have no reason to believe that the Registration Statement, at
the effective date, contained any untrue statement of a material fact or omitted
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading or that the Base Prospectus, as
supplemented by the Prospectus Supplement, as of the date of the Prospectus
Supplement, contained any untrue statement of a material fact or omitted to
state a material fact necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading; it being
understood that I express no views as to the financial

                                      E-3


statements or other financial data contained or incorporated by reference in the
Registration Statement or the Prospectus. Also, nothing has come to my attention
in the course of my examination of the Registration Statement or the Prospectus
that has caused me to believe that the Prospectus, as of the date and time of
the delivery of this letter, contained any untrue statement of a material fact
or omitted to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

                                                              Very truly yours,



                                                              Robert W. Stahman
