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 $350,000,000 aggregate principal amount of its First Mortgage Bonds, Secured Medium-Term Notes, Series H, 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 Forty-fourth Supplemental Indenture relating to the Notes dated as of April 1, 2008 (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 any 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 are 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, each of you as set forth below in this Section 1.  Certain terms used in this Section 1 are defined in paragraph (j) 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 Form S-3 (File No. 333-147807), including a prospectus, for the registration under the Act of $350,000,000 aggregate principal amount of its first mortgage bonds and debt securities (the “ Securities ”), including the Notes, which registration statement was declared effective by the Commission on December 18, 2007; and no stop order suspending the effectiveness of the registration statement has been issued and no proceeding for that purpose has been instituted or, to the Company’s knowledge, threatened by the Commission.  The parts of the registration statement, including all exhibits thereto and the documents filed under the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”), that are incorporated by reference in the prospectus contained in the registration statement at the time such part of the registration statement became effective, each as amended at the time each such part of the registration statement most recently became effective, are hereinafter

collectively called the “ Registration Statement ,” and such times are hereinafter collectively called the “ applicable effective date ” of the Registration Statement.  The Registration Statement meets the requirements set forth in Rule 415(a)(1)(ix) or (x) under the Act.  The prospectus dated December 18, 2007 contained in the registration statement is hereinafter referred to as the “ Base Prospectus .”  In connection with the sale of the Notes, the Company has filed or proposes to file with the Commission pursuant to Rule 424(b) under the Act a prospectus supplement relating to the Notes (the “ Prospectus Supplement ”) and further supplements (each a “ Pricing Supplement ”) specifying the interest rates, maturity dates and other terms of the Notes to be sold pursuant hereto or the offering thereof (the Base Prospectus as supplemented by the Prospectus Supplement and any applicable Pricing Supplement being referred to herein as the “ Prospectus ”).  Any reference herein to the Registration Statement, the Base Prospectus or the Prospectus shall be deemed to refer to and include the documents filed under the Exchange Act and incorporated by reference therein on or before the applicable effective date of the Registration Statement or the issue date of the Base Prospectus 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 Base Prospectus or the Prospectus shall be deemed to refer to and include any documents filed under the Exchange Act and incorporated by reference therein after the applicable effective date of the Registration Statement or the issue date of the Base Prospectus or the Prospectus, as the case may be.

(b)   (i) On the applicable effective date the Registration Statement complied, and as of the Execution Time the Registration Statement as amended or supplemented complies, in all material respects with the applicable requirements of the Act and the Trust Indenture Act of 1939, as amended (the “ Trust Indenture Act ”), and with the rules and regulations of the Commission thereunder; (ii) on each date any supplement to the Prospectus relating to the Notes is filed with the Commission and at the date of delivery by the Company of any Notes sold hereunder (a “ Closing Date ”), the Prospectus, as amended or supplemented, will comply in all material respects with the applicable requirements of the Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder; (iii) as of the applicable effective date the Registration Statement did not, as of the Execution Time the Prospectus does not, and as of the Applicable Time the Pricing Disclosure Package will 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, and in the case of the Prospectus and the Pricing Disclosure Package, in the light of the circumstances under which they were made, not misleading and (iv) on any Closing Date, the Prospectus, as amended or supplemented, will 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, in the light of the circumstances under which they were made, not misleading; provided , however , that the Company makes no representations or warranties as to (A) 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 (B) the information contained in or omitted from the Registration Statement, the Prospectus or any amendments or supplements thereto or the Pricing Disclosure Package in reliance upon and in conformity with information, if any, furnished in writing to the Company by any of you specifically for inclusion therein.

(c)   Other than the Base Prospectus, the Prospectus, any documents listed in Annex I to any Terms Agreement, or any document not constituting a prospectus under

3

Section 2(a)(10)(a) of the Act or Rule 134 under the Act, the Company (including its agents and representatives, other than you) has not made, used, prepared, authorized, approved or referred to and will not make, use, prepare, authorize, approve or refer to, any “written communication” (as defined in Rule 405 under the Act) that constitutes an offer to sell or solicitation of an offer to buy the Notes, unless such written communication is approved in writing in advance by such of you as may be applicable.  To the extent any such written communication constitutes an “issuer free writing prospectus” (as defined in Rule 433 under the Act and referred to herein as an “ Issuer Free Writing Prospectus ”), such Issuer Free Writing Prospectus will comply in all material respects with the requirements of Rule 433(c) under the Act and, if the filing thereof is required pursuant to Rule 433, such filing will be made in the manner and within the time period required by Rule 433(d) under the Act.  The Company will retain copies of each such Issuer Free Writing Prospectus in accordance with Rule 433 under the Act if retention is required pursuant to Rule 433.

(d)   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.

(e)   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 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 are subject, nor will such action result in any violation of the provisions of the Restated Articles of Incorporation, as amended or Bylaws 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, qualification of or registration 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 January 11, 2010), 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.

(f)    The Company maintains a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act). The Company’s internal control over financial reporting was effective as of December 31, 2007 and the Company is not aware of any material weaknesses in its internal control over financial reporting.

4

(g)   Since the date of the latest audited financial statements included or incorporated by reference in the Prospectus, there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

(h)   The Company maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) of the Exchange Act) that were effective as of December 31, 2007.

(i)    At the earliest time after the filing of the registration statement that the Company makes a bona fide offer (within the meaning of Rule 164(h)(2) under the Act) of the Notes, the Company will not be an “ineligible issuer,” as defined in Rule 405 under the Act.

(j)    The terms that follow, when used in this Agreement, shall have the meanings indicated.  The term “ Execution Time ” shall mean the date and time that this Agreement is executed and delivered by the parties hereto.  With respect to any issue of Notes, (A) the “ Applicable Time ” will be (i) with respect to Notes sold to a Purchaser, such time as is specified in the applicable Terms Agreement as the Applicable Time, or, if the Terms Agreement does not specify the Applicable Time, the Applicable Time shall mean the time of the first sale (including, without limitation, a contract of sale) by the Company to a Purchaser of such Notes, or (ii) with respect to Notes sold by an Agent, the Applicable Time shall mean each time of sale (including, without limitation, a contract of sale) of such Notes, and (B) the “ Pricing Disclosure Package ” shall mean the Prospectus as amended or supplemented immediately prior to the Applicable Time taken together with any final term sheet in the form set forth in Annex II to the applicable Terms Agreement (the “ Final Term Sheet ”), any Issuer Free Writing Prospectus and any other free writing prospectus that the Company and such Agent shall expressly agree in writing to include as part of the Pricing Disclosure Package with respect to such issue of Notes.

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 appoints 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 as amended or supplemented from time to time 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 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).

5

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.

Each Agent represents and agrees that, unless it obtains the prior consent of the Company, it has not made and will not make any offer relating to the Notes (other than by means of a Final Term Sheet) that would constitute a “free writing prospectus,” as defined in Rule 405 under the Act, required to be filed with the Commission.

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, at 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 that 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, the rate at which interest will be paid on such Notes, the dates on which interest will be paid on

6

such Notes and the record date with respect to each such payment of interest, the Applicable Time with respect to such Notes, the Closing Date, 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 registered public accounting firm 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 or supplement to the Registration Statement or 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 shall cause each supplement to the Prospectus to be filed with the Commission pursuant to the

7

applicable paragraph of Rule 424(b) under the Act within the time period prescribed and shall provide evidence satisfactory to you of such filing.

To the extent required under the Act, the Company also agrees to prepare, prior to the termination of the offering of the Notes, with respect to any Notes to be sold pursuant to this Agreement, an Issuer Free Writing Prospectus that is a Final Term Sheet, and to file such Final Term Sheet pursuant to Rule 433(d) under the Act within the time required by such rule.

The Company will promptly advise each of you (i) when the Prospectus, any supplement thereto and any Issuer Free Writing Prospectus has been filed with the Commission pursuant to Rule 424(b) or Rule 433(d) under the Act, (ii) when, prior to termination of any offering of Notes, any amendment to the Registration Statement (except periodic or current reports filed under the Exchange Act) has been filed or become effective, (iii) of any request by the Commission for any amendment or supplement to the Registration Statement or 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 following the relevant Applicable Time, when a prospectus relating to the Notes is required to be delivered under the Act, any event occurs as a result of which (i) the Prospectus, the Final Term Sheet or any Issuer Free Writing Prospectus as then amended or 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; (ii) it is necessary to amend or supplement the Registration Statement, the Prospectus, the Final Term Sheet or any Issuer Free Writing Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder or (iii) the information contained in an Issuer Free Writing Prospectus conflicts with information contained in the Registration Statement or the Prospectus that has not been superseded or modified, the Company will promptly (x) 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), (y) prepare and file with the Commission, subject to the first sentence of paragraph (a) of this Section 4, an amendment or supplement to the Registration Statement, the Prospectus, the Issuer Free Writing Prospectus or the Final Term Sheet, which will correct such statement or omission or effect such compliance and (z) supply any supplemented Prospectus, Final Term Sheet or Issuer Free Writing 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

8

the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act and, to the extent such documents are not available pursuant to the EDGAR filing system, 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, as many copies of the Registration Statement (including exhibits thereto), and, so long as delivery of a prospectus may be required by the Act, the Prospectus and each additional prospectus supplement, the Final Term Sheet, any Issuer Free Writing Prospectus, and each amendment or supplement to the Indenture entered into subsequent to the date hereof, as you may reasonably request.

(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, and 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, the Final Term Sheet, any Issuer Free Writing Prospectus, 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, the Prospectus as amended or supplemented at each such time and any Issuer Free Writing Prospectus relating to the Notes).  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

9

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, the Company shall deliver or cause to be delivered promptly to 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.

(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, the Company shall furnish or cause to be furnished promptly to 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 or, in lieu of such opinion, counsel last furnishing such an opinion to you may furnish you with a letter to the effect that you may rely on such last opinion to the same extent as though it were dated the date of such letter authorizing reliance (except that statements in such last opinion will be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented to the time of the effectiveness of such amendment or the filing of such supplement).

(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, the Company shall cause its independent registered public accounting firm promptly to furnish you a letter, dated five business days after the date of the effectiveness of such amendment or the date of filing of such supplement, in form reasonably satisfactory to you, of the same tenor as the letter referred to in Section 5(e) with such changes as may be necessary to reflect the amended and supplemental financial information included or incorporated by reference in the Registration Statement and the Prospectus, as amended or supplemented to the date of such letter; provided , however , that, if the Registration Statement or the Prospectus is amended or supplemented solely to include or incorporate by reference financial information as of and for a fiscal quarter, the Company’s independent registered public accounting firm may limit the scope of such letter, which shall be satisfactory in form to 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 your reasonable judgment, such letter should cover other information or changes in specified financial statement line items.

10

(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 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) to the extent such documents are not available pursuant to the EDGAR filing system, copies of all annual, quarterly and current reports (without exhibits) of the Company filed with the Commission under the Exchange Act, (ii) copies of all announcements made to the general financial community and (iii) 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 that 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 that 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, 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) under the Act, the Prospectus, and any supplement, shall have been filed in the manner and within the time period required by Rule 424(b) under the Act; 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.

11

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

13

prospectus supplement, the Registration Statement, the Prospectus, any amendment or supplement thereto or any Issuer Free Writing Prospectus, 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, any amendment or supplement thereto or any Issuer Free Writing Prospectus 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.  This indemnity agreement shall be in addition to any liability that 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, that controls any of you within the meaning of the Act.

(b)          Each of you severally and not jointly shall 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, any amendment or supplement thereto or any Issuer Free Writing Prospectus, 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 any preliminary prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus, any amendment or supplement thereto or any Issuer Free Writing Prospectus 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 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 that 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, that 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

14

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 required to be stated therein or necessary in order to make the statements therein not misleading 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 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

15

are several in proportion to the respective sales made by or through you to the public 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 sixth paragraph of Section 2(a), Section 4(g), Section 7 and Section 9 hereof.

(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 proceed with the offer, sale or delivery of Notes in the manner contemplated in the Pricing Disclosure Package, the Prospectus and this Agreement, (ii) there shal
