Item 5.  Interests of Named Experts and Counsel.
-------  ---------------------------------------

        Thomas R. Saldin, Esq., our Senior Vice President and General Counsel,
and LeBoeuf, Lamb, Greene & MacRae LLP, New York, New York have given their
opinions on the legality of the common stock and the preferred share purchase
rights offered pursuant to this registration statement. LeBoeuf, Lamb, Greene &
MacRae LLP relied upon the opinion of Mr. Saldin as to matters of Idaho law.

        As of May 1, 2007, Mr. Saldin owned 17,542 shares of IDACORP common
stock, including shares that may be acquired within 60 days pursuant to the
exercise of stock options. Mr. Saldin is acquiring additional shares of IDACORP
common stock at regular intervals through employee stock plans.

Item 6.  Indemnification of Directors and Officers.
-------  ------------------------------------------

        Sections 30-1-851 et seq. of the Idaho Business Corporation Act provide
for indemnification of IDACORP's directors and officers in a variety of
circumstances.

        Article VIII of IDACORP's articles of incorporation, as amended,
provides that IDACORP shall indemnify its directors and officers against
liability and expenses and shall advance expenses to its directors and officers
in connection with any proceeding to the fullest extent permitted by the Idaho
Business Corporation Act as now in effect or as it may be amended or substituted
from time to time. Article VI of IDACORP's bylaws provides that IDACORP shall
have the power to purchase and maintain insurance on behalf of any director,
officer, employee or agent against liability and expenses in connection with any
proceeding, to the extent permitted under applicable law. Article VI further
provides that IDACORP may enter into indemnification agreements with any
director, officer, employee or agent to the extent permitted under any
applicable law.

        IDACORP has liability insurance protecting its directors and officers
against liability by reason of their being or having been directors or officers.
In addition, IDACORP has entered into indemnification agreements with its
directors and officers to provide for indemnification to the maximum extent
permitted by law.

Item 9.  Undertakings.
-------  -------------

        (a) The undersigned registrant hereby undertakes:

              (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:


                                      II-3


               (i) To include any prospectus required by section 10(a)(3) of the
        Securities Act of 1933;

               (ii) To reflect in the prospectus any facts or events arising
        after the effective date of the registration statement (or the most
        recent post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20 percent change
        in the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement;

               (iii) To include any material information with respect to the
        plan of distribution not previously disclosed in the registration
        statement or any material change to such information in the registration
        statement;

Provided, however, That:

               (A) Paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not
        apply if the registration statement is on Form S-8, and the information
        required to be included in a post-effective amendment by those
        paragraphs is contained in reports filed with or furnished to the
        Commission by the registrant pursuant to section 13 or section 15(d) of
        the Securities Exchange Act of 1934 that are incorporated by reference
        in the registration statement; and

               (B) Paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this
        section do not apply if the registration statement is on Form S-3 or
        Form F-3 and the information required to be included in a post-effective
        amendment by those paragraphs is contained in reports filed with or
        furnished to the Commission by the registrant pursuant to section 13 or
        section 15(d) of the Securities Exchange Act of 1934 that are
        incorporated by reference in the registration statement, or is contained
        in a form of prospectus filed pursuant to Rule 424(b) that is part of
        the registration statement;

               (C) Provided further, however, that paragraphs (a)(1)(i) and
        (a)(1)(ii) do not apply if the registration statement is for an offering
        of asset-backed securities on Form S-1 or Form S-3, and the information
        required to be included in a post-effective amendment is provided
        pursuant to Item 1100(c) of Regulation AB.

             (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

             (3) To remove from registration by means of a post-effective
amendment any of the securities being registered that remain unsold at the
termination of the offering.

        (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to


                                      II-4


section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and,
where applicable, each filing of an employee benefit plan's annual report
pursuant to section 15(d) of the Securities Exchange Act of 1934) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

        (h) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the provisions described under Item 6
above, or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
