AVISTA CORPORATION Avista Corp., formerly known as The Washington Water Power Company, was incorporated in the State of Washington in 1889, and is a diversified energy services company. Avista Corp.'s subsidiaries include Avista Energy, Avista Advantage, Avista Labs and Pentzer Corporation. At December 31, 1998, Avista Corp.'s employees included 1,536 people in its utility operations and approximately 2,153 people in its majority-owned non-regulated businesses (energy and non-energy). Avista Corp.'s corporate headquarters are located at 1411 East Mission Avenue, Spokane, Washington 99220, which serves as the Inland Northwest's center for manufacturing, transportation, health care, education, communication, agricultural and service businesses. The Company's operations are organized into four lines of business, two of which comprise its utility operations. The Energy Delivery business provides electricity and natural gas in a 26,000 square-mile area in eastern Washington and northern Idaho, with a combined population of approximately 825,000, as of December 31, 1998, as well as natural gas services in a 4,000 square-mile area in northeast and southwest Oregon and South Lake Tahoe region of California, with a combined population of approximately 459,000, as of such date. The Generation and Resources business includes the generation and production of electric energy, and short- and long-term electric and natural gas wholesale sales and wholesale marketing primarily to, and commodity trading with, other utilities and power brokers in the Western System Coordinating Council. The National Energy Trading and Marketing business, which is conducted through subsidiaries, focuses on commodity trading, energy marketing and energy related products and services on a national basis. The non-energy business primarily consists of Pentzer, a private investment firm. Regulatory, economic and technological changes have brought about the accelerating transformation of the electric utility industry from a vertically integrated monopoly to separate market driven businesses. Changes underway in the utility and energy industries are creating new opportunities to expand Avista Corp.'s businesses and serve new markets. In pursuing such opportunities, Avista Corp. is shifting its strategic direction to growth in order to achieve its goal of becoming a diversified North American energy company. USE OF PROCEEDS Avista Corp. intends to use the net proceeds from the issuance and sale of the debt securities offered by this prospectus (the "Debt Securities") for any or all of the following purposes: (a) to fund a portion of Avista Corp.'s construction, facility improvement and maintenance programs, (b) to retire or exchange one or more outstanding series of its preferred stock, bonds or long-term notes, (c) to reduce or eliminate short-term debt issued for any of these purposes, (d) to reimburse Avista Corp.'s treasury for funds previously expended for these purposes and (e) for other corporate purposes. Avista Corp. also has an existing shelf registration statement on file with the SEC for the issuance and sale of Medium-Term Notes, Series C. As of June 30, 1999, Avista Corp. had $166,000,000 of Medium-Term Notes, Series C available for issuance and sale, the net proceeds from which may be used for purposes similar to those enumerated above. The prospectus supplement relating to each series or tranche of the Debt Securities will indicate the expected use of the proceeds of that series or tranche. 4

DESCRIPTION OF THE DEBT SECURITIES GENERAL Avista Corp. may issue the Debt Securities in one or more series, or in one or more tranches within a series, under an Indenture, dated as of April 1, 1998 (the "Original Indenture"), between Avista Corp. and The Chase Manhattan Bank, as trustee (the "Trustee"), the Original Indenture, as amended and supplemented from time to time, being hereinafter referred to as the Indenture. The terms of the Debt Securities will include those stated in the Indenture and those made part of the Indenture by the Trust Indenture Act. The following summary is not complete and is subject in all respects to the provisions of, and is qualified in its entirety by reference to, the Indenture and the Trust Indenture Act. Avista Corp. has filed the Indenture, as well as a form of officer's certificate to establish a series of debt securities, as an exhibit to the registration statement of which this prospectus is a part. Capitalized terms used under this heading which are not otherwise defined in this prospectus have the meanings set forth in the Indenture. Wherever particular provisions of the Indenture or terms defined in the Indenture are referred to, those provisions or defined terms are incorporated by reference as part of the statements made in this prospectus and the statements are qualified in their entirety by that reference. References to article and section numbers, unless otherwise indicated, are references to article and section numbers in the Indenture. In addition to the Debt Securities, other debt securities may be issued under the Indenture, without any limit on the aggregate principal amount. The Debt Securities and all other debt securities issued under the Indenture are collectively referred to as the "Indenture Securities." Each series of Indenture Securities will be unsecured and will rank pari passu with all other series of Indenture Securities, except as otherwise provided in the Indenture, and with all other unsecured and unsubordinated indebtedness of Avista Corp. Except as otherwise described in the applicable prospectus supplement, the Indenture does not limit the incurrence or issuance by Avista Corp. of other secured or unsecured debt, whether under the Indenture, any other indenture that Avista Corp. may enter into in the future, or otherwise. See the prospectus supplement relating to any offering of Debt Securities. The applicable prospectus supplements will describe the following terms of the Debt Securities of each series or tranche: (a) the title of the Debt Securities; (b) any limit upon the aggregate principal amount of the Debt Securities; (c) the date or dates on which the principal of the Debt Securities is payable or the method of determination thereof and the right, if any, to extend such date or dates; (d) the rate or rates at which the Debt Securities will bear interest, if any, or the method by which such rate or rates, if any, will be determined, the date or dates from which any such interest will accrue, the interest payment dates on which any such interest will be payable, the right, if any, of Avista Corp. to defer or extend an interest payment date, and the regular record date for any interest payable on any interest payment date and the person or persons to whom interest on such Debt Securities will be payable on any interest payment date, if other than the person or persons in whose names such Debt Securities are registered at the close of business on the regular record date for such interest; 5

(e) the place or places where, subject to the terms of the Indenture as described below under "Payment and Paying Agents", the principal of and premium, if any, and interest, if any, on the Debt Securities will be payable and where, subject to the terms of the Indenture as described below under "Registration and Transfer", the Debt Securities may be presented for registration of transfer or exchange and the place or places where notices and demands to or upon Avista Corp. in respect of the Debt Securities and the Indenture may be served; the Security Registrar and Paying Agents for the Debt Securities; and, if such is the case, that the principal of the Debt Securities will be payable without presentation or surrender; (f) any period or periods within which, or date or dates on which, the price or prices at which and the terms and conditions upon which the Debt Securities may be redeemed, in whole or in part, at the option of Avista Corp.; (g) the obligation or obligations, if any, of Avista Corp. to redeem or purchase any of the Debt Securities pursuant to any sinking fund or other mandatory redemption provisions or at the option of the Holder, any period or periods within which, or date or dates on which, the price or prices at which and the terms and conditions upon which the Debt Securities will be redeemed or purchased, in whole or in part, pursuant to such obligation, and applicable exceptions to the requirements of a notice of redemption in the case of mandatory redemption or redemption at the option of the Holder; (h) the denominations in which any of the Debt Securities will be issuable if other than denominations of $1,000 and any integral multiple of $1,000; (i) if the Debt Securities are to be issued in global form, the identity of the depositary; and (j) any other terms of the Debt Securities. PAYMENT AND PAYING AGENTS Except as may be provided in the applicable prospectus supplement, Avista Corp. will pay interest, if any, on each Debt Security on each interest payment date to the person in whose name such Debt Security is registered (the registered holder of any Indenture Security being called a "Holder") as of the close of business on the regular record date relating to such interest payment date; provided, however, that Avista Corp. will pay interest at maturity (whether at stated maturity, upon redemption or otherwise, "Maturity") to the person to whom principal is paid. However, if there has been a default in the payment of interest on any Debt Security, such defaulted interest may be payable to the Holder of such Debt Security as of the close of business on a date selected by the Trustee which is not more than 30 days and not less than 10 days before the date proposed by Avista Corp. for payment of such defaulted interest or in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Debt Security may be listed, if the Trustee deems such manner of payment practicable. (See Section 307.) Unless otherwise specified in the applicable prospectus supplement, Avista Corp. will pay the principal of and premium, if any, and interest, if any, on the Debt Securities at Maturity upon presentation of the Debt Securities at the corporate trust office of The Chase Manhattan Bank in New York, New York, as Paying Agent for Avista Corp. Avista Corp. may change the place of payment of the Debt Securities, may appoint one or more additional Paying Agents (including Avista Corp.) and may remove any paying agent, all at its discretion. (See Section 502.) 6

REGISTRATION AND TRANSFER Unless otherwise specified in the applicable prospectus supplement, Holders may register the transfer of Debt Securities, and may exchange Debt Securities of the same series and tranche, of authorized denominations and having the same terms and aggregate principal amount, at the corporate trust office of The Chase Manhattan Bank in New York, New York, as security registrar for the Debt Securities. Avista Corp. may change the place for registration of transfer and exchange of the Debt Securities, may appoint one or more additional security registrars (including Avista Corp.) and may remove any security registrar, all at its discretion. Except as otherwise provided in the applicable prospectus supplement, no service charge will be made for any transfer or exchange of the Debt Securities, but Avista Corp. may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of the Debt Securities. Avista Corp. will not be required to execute or to provide for the registration of transfer of or the exchange of (a) any Debt Security during a period of 15 days before giving any notice of redemption or (b) any Debt Security selected for redemption in whole or in part, except the unredeemed portion of any Debt Security being redeemed in part. (See Section 305.) REDEMPTION The applicable prospectus supplement will set forth any terms for the optional or mandatory redemption of Debt Securities. Except as otherwise provided in the applicable prospectus supplement with respect to Debt Securities redeemable at the option of the Holder, Debt Securities will be redeemable only upon notice by mail not less than 30 nor more than 60 days before the date fixed for redemption. If less than all the Debt Securities of a series, or any tranche thereof, are to be redeemed, the particular Debt Securities to be redeemed will be selected by such method as shall be provided for such series or tranche, or in the absence of any such provision, by such method of random selection as the Security Registrar deems fair and appropriate. (See Sections 403 and 404.) Any notice of redemption at the option of Avista Corp. may state that such redemption will be conditional upon receipt by the Paying Agent or Agents, on or before the date fixed for such redemption, of money sufficient to pay the principal of and premium, if any, and interest, if any, on such Debt Securities and that if such money has not been received, such notice will be of no force or effect and Avista Corp. will not be required to redeem such Debt Securities. (See Section 404.) SATISFACTION AND DISCHARGE Any Indenture Securities, or any portion of the principal amount thereof, will be deemed to have been paid for purposes of the Indenture and, at Avista Corp.'s election, the entire indebtedness of Avista Corp. in respect thereof will be deemed to have been satisfied and discharged, if there shall have been irrevocably deposited with the Trustee or any Paying Agent (other than Avista Corp.), in trust: (a) money in an amount which will be sufficient, or (b) in the case of a deposit made before the maturity of such Indenture Securities, Eligible Obligations, which do not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, the principal of and the interest on which when due, without any regard to reinvestment thereof, will provide moneys which, together with the money, if any, deposited with or held by the Trustee or such Paying Agent, will be sufficient, or 7

(c) a combination of (a) and (b) which will be sufficient, to pay when due the principal of and premium, if any, and interest, if any, due and to become due on such Indenture Securities. For this purpose, Eligible Obligations include direct obligations of, or obligations unconditionally guaranteed by, the United States entitled to the benefit of the full faith and credit thereof and certificates, depositary receipts or other instruments which evidence a direct ownership interest in such obligations or in any specific interest or principal payments due in respect thereof and such other obligations or instruments as shall be specified in an accompanying prospectus supplement. (See Section 601.) The Indenture will be deemed to have been satisfied and discharged when no Indenture Securities remain outstanding thereunder and Avista Corp. has paid or caused to be paid all other sums payable by Avista Corp. under the Indenture. (See Section 602.) EVENTS OF DEFAULT Any one or more of the following events with respect to a series of Indenture Securities that has occurred and is continuing will constitute an "Event of Default" with respect to such series of Indenture Securities: (a) failure to pay interest on any Indenture Security of such series within 60 days after the same becomes due and payable; provided, however, that no such failure will constitute an Event of Default if Avista Corp. has made a valid extension of the interest payment period with respect to the Indenture Securities of such series if so provided with respect to such series; or (b) failure to pay the principal of or premium, if any, on any Indenture Security of such series within 3 business days after its Maturity; provided, however, that no such failure will constitute an Event of Default if Avista Corp. has made a valid extension of the Maturity of the Indenture Securities of such series, if so provided with respect to such series; or (c) failure to perform, or breach of, any covenant or warranty of Avista Corp. contained in the Indenture for 90 days after written notice to Avista Corp. from the Trustee or to Avista Corp. and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Indenture Securities of such series as provided in the Indenture unless the Trustee, or the Trustee and the Holders of a principal amount of Securities of such series not less than the principal amount of Indenture Securities the Holders of which gave such notice, as the case may be, agree in writing to an extension of such period before its expiration; provided, however, that the Trustee, or the Trustee and the Holders of such principal amount of Indenture Securities of such series, as the case may be, will be deemed to have agreed to an extension of such period if corrective action is initiated by Avista Corp. within such period and is being diligently pursued; or (d) default under any bond, debenture, note or other evidence of indebtedness of Avista Corp. for borrowed money (including Indenture Securities of other series) or under any mortgage, indenture, or other instrument to evidence any indebtedness of Avista Corp. for borrowed money, which default (1) constitutes a failure to make any payment in excess of $5,000,000 of the principal of, or interest on, such indebtedness or (2) has resulted in such indebtedness in an amount in excess of $10,000,000 becoming or being declared due and payable prior to the date it would otherwise have become due and payable, without such payment having been made, such indebtedness having been discharged, or such 8

acceleration having been rescinded or annulled, within a period of 90 days after written notice to Avista Corp. by the Trustee or to Avista Corp. and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of such series as provided in the Indenture; or (e) certain events in bankruptcy, insolvency or reorganization of Avista Corp. (See Section 701.) (See Section 701.) REMEDIES Acceleration of Maturity If an Event of Default applicable to the Indenture Securities of any series occurs and is continuing, then either the Trustee or the Holders of not less than 33% in aggregate principal amount of the Outstanding Indenture Securities of such series may declare the principal amount (or, if any of the Indenture Securities of such series are Discount Securities, such portion of the principal amount thereof as may be specified in the terms thereof) of all of the Outstanding Indenture Securities of such series to be due and payable immediately by written notice to Avista Corp. (and to the Trustee if given by Holders); provided, however, that if an Event of Default occurs and is continuing with respect to more than one series of Indenture Securities, the Trustee or the Holders of not less than 33% in aggregate principal amount of the Outstanding Indenture Securities of all such series, considered as one class, may make such declaration of acceleration and not the Holders of the Indenture Securities of any one such series. At any time after such a declaration of acceleration with respect to the Indenture Securities of any series has been made, but before a judgment or decree for payment of the money due has been obtained, such declaration and its consequences will, without further act, be deemed to have been rescinded and annulled, if (a) Avista Corp. has paid or deposited with the Trustee a sum sufficient to pay (1) all overdue interest, if any, on all Indenture Securities of such series; (2) the principal of and premium, if any, on any Indenture Securities of such series which have become due otherwise than by such declaration of acceleration and interest, if any, thereon at the rate or rates prescribed therefor in such Indenture Securities; (3) interest, if any, upon overdue interest, if any, at the rate or rates prescribed therefor in such Indenture Securities, to the extent that payment of such interest is lawful; and (4) all amounts due to the Trustee under the Indenture in respect of compensation and reimbursement of expenses; and (b) all Events of Default with respect to Indenture Securities of such series, other than the non-payment of the principal of the Indenture Securities of such series which has become due solely by such declaration of acceleration, have been cured or waived as provided in the Indenture. (See Section 702.) 9

Right to Direct Proceedings If an Event of Default with respect to the Indenture Securities of any series occurs and is continuing, the Holders of a majority in principal amount of the Outstanding Indenture Securities of such series will have the right to direct the time, method and place of conducting any proceedings for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee; provided, however, that if an Event of Default occurs and is continuing with respect to more than one series of Indenture Securities, the Holders of a majority in aggregate principal amount of the Outstanding Indenture Securities of all such series, considered as one class, will have the right to make such direction, and not the Holders of the Indenture Securities of any one of such series; and provided, further, that (a) such direction does not conflict with any rule of law or with the Indenture, and could not involve the Trustee in personal liability in circumstances where indemnity would not, in the Trustee's sole discretion, be adequate and (b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. (See Section 712.) Limitation on Right to Institute Proceedings No Holder of any Indenture Security will have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or for any other remedy thereunder unless: (a) such Holder has previously given to the Trustee written notice of a continuing Event of Default with respect to the Indenture Securities of any one or more series; (b) the Holders of a majority in aggregate principal amount of the outstanding Indenture Securities of all series in respect of which such Event of Default has occurred, considered as one class, have made written request to the Trustee to institute proceedings in respect of such Event of Default and have offered the Trustee reasonable indemnity against costs and liabilities to be incurred in complying with such request; and (c) for 60 days after receipt of such notice, the Trustee has failed to institute any such proceeding and no direction inconsistent with such request has been given to the Trustee during such 60 day period by the Holders of a majority in aggregate principal amount of Indenture Securities then outstanding. Furthermore, no Holder of Indenture Securities of any series will be entitled to institute any such action if and to the extent that such action would disturb or prejudice the rights of other Holders of Indenture Securities of such series. (See Section 707.) No Impairment of Right to Receive Payment Notwithstanding that the right of a Holder to institute a proceeding with respect to the Indenture is subject to certain conditions precedent, each Holder of an Indenture Security will have the right, which is absolute and unconditional, to receive payment of the principal of and premium, if any, and interest, if any, on such Indenture Security when due and to institute suit for the enforcement of any such payment, and such rights may not be impaired or affected without the consent of such Holder. (See Section 708.) 10

Notice of Default The Trustee is required to give the Holders notice of any default under the Indenture to the extent required by the Trust Indenture Act, unless such default shall have been cured or waived, except that no such notice to Holders of a default of the character described in clause (c) under "- Events of Default" may be given until at least 75 days after the occurrence thereof. For purposes of the preceding sentence, the term "default" means any event which is, or after notice or lapse of time, or both, would become, an Event of Default. The Trust Indenture Act currently permits the Trustee to withhold notices of default (except for certain payment defaults) if the Trustee in good faith determines the withholding of such notice to be in the interests of the Holders. (See Section 802.) CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS Avista Corp. may not consolidate with or merge into any other Person, or convey or otherwise transfer, or lease, all of its properties, as or substantially as an entirety, to any Person, unless: (a) the Person formed by such consolidation or into which Avista Corp. is merged or the Person which acquires by conveyance or other transfer, or which leases (for a term extending beyond the last Stated Maturity of the Indenture Securities then Outstanding), all of the properties of Avista Corp., as or substantially as an entirety, shall be a Person organized and existing under the laws of the United States, any State or Territory thereof or the District of Columbia or under the laws of Canada or any Province thereof; and (b) such Person shall expressly assume the due and punctual payment of the principal of and premium, if any, and interest, if any, on all the Indenture Securities then Outstanding and the performance and observance of every covenant and condition of the Indenture to be performed or observed by Avista Corp. In the case of the conveyance or other transfer of all of the properties of Avista Corp., as or substantially as an entirety, to any person as contemplated above, Avista Corp. would be released and discharged from all obligations under the Indenture and on all Indenture Securities then outstanding unless Avista Corp. elects to waive such release and discharge. Upon any such consolidation or merger or any such conveyance or other transfer of properties of Avista Corp., the successor, transferee or lessee would succeed to, and be substituted for, and would be entitled to exercise every power and right of, Avista Corp. under the Indenture. (See Sections 1001, 1002 and 1003.) For purposes of the Indenture, the conveyance, transfer or lease by Avista Corp. of all of its facilities: (a) for the generation of electric energy, (b) for the transmission of electric energy, (c) for the distribution of electric energy and/or natural gas, in each case considered alone, (d) all of its facilities described in clauses (a) and (b), considered together, or (e) all of its facilities described in clauses (b) and (c), considered together, 11

will in no event be deemed to constitute a conveyance or other transfer of all the properties of Avista Corp., as or substantially as an entirety, unless, immediately following such conveyance, transfer or lease, Avista Corp. owns no unleased properties in the other such categories of property not so conveyed or otherwise transferred or leased. The Indenture will not prevent or restrict: (a) any consolidation or merger after the consummation of which Avista Corp. would be the surviving or resulting entity, or (b) any conveyance or other transfer, or lease, of any part of the properties of Avista Corp. which does not constitute the entirety, or substantially the entirety, thereof. (See Section 1004.) If Avista Corp. conveys or otherwise transfers any part of its properties which does not constitute the entirety, or substantially the entirety, thereof to another Person meeting the requirements set forth in the first paragraph under this heading, and if: (a) such transferee expressly assumes the due and punctual payment of the principal of and premium, if any, and interest, if any, on all Indenture Securities then outstanding and the performance and observance of every covenant and condition of the Indenture to be performed or observed by Avista Corp.; and (b) there is delivered to the Trustee an independent expert's certificate (i) describing the property so conveyed or transferred and identifying the same as facilities for the generation, transmission or distribution of electric energy or for the storage, transportation or distribution of natural gas and (ii) stating that the aggregate principal amount of the Indenture Securities then outstanding does not exceed 70% of the fair value of such property, then Avista Corp. would be released and discharged from all obligations and covenants under the Indenture and on all Indenture Securities then outstanding unless Avista Corp. elects to waive such release and discharge. In such event, the transferee would succeed to, and be substituted for, and would be entitled to exercise every right and power of, Avista Corp. under the Indenture. (See Section 1005.) MODIFICATION OF INDENTURE Modifications Without Consent Avista Corp. and the Trustee may enter into one or more supplemental indentures, without the consent of any Holders of Indenture Securities, for any of the following purposes: (a) to evidence the succession of another Person to Avista Corp. and the assumption by any such successor of the covenants of Avista Corp. in the Indenture and in the Indenture Securities; or (b) to add one or more covenants of Avista Corp. or other provisions for the benefit of all Holders of Indenture Securities or for the benefit of the Holders of, or to remain in effect only so long as there shall be Outstanding, Indenture Securities of one or more specified series, or one or 12

more Tranches thereof, or to surrender any right or power conferred upon Avista Corp. by the Indenture; or (c) to change or eliminate any provision of the Indenture or to add any new provision to the Indenture, provided that if such change, elimination or addition adversely affects the interests of the Holders of the Indenture Securities of any series or Tranche in any material respect, such change, elimination or addition will become effective with respect to such series or Tranche only when no Indenture Security of such series or Tranche remains Outstanding; or (d) to provide collateral security for the Indenture Securities or any series thereof; or (e) to establish the form or terms of the Indenture Securities of any series or Tranche as permitted by the Indenture; or (f) to provide for the authentication and delivery of bearer securities and coupons appertaining thereto representing interest, if any, thereon and for the procedures for the registration, exchange and replacement thereof and for the giving of notice to, and the solicitation of the vote or consent of, the Holders thereof, and for any and all other matters incidental thereto; or (g) to evidence and provide for the acceptance of appointment by a successor trustee with respect to the Indenture Securities of one or more series; or (h) to provide for the procedures required to permit the utilization of a non-certificated system of registration for all, or any series or Tranche of, the Indenture Securities; or (i) to change any place or places where (1) the principal of and premium, if any, and interest, if any, on all or any series of Indenture Securities, or any Tranche thereof, will be payable, (2) all or any series of Indenture Securities, or any Tranche thereof, may be surrendered for registration of transfer, (3) all or any series of Indenture Securities, or any Tranche thereof, may be surrendered for exchange and (4) notices and demands to or upon Avista Corp. in respect of all or any series of Indenture Securities, or any Tranche thereof, and the Indenture may be served; or (j) to cure any ambiguity, to correct or supplement any provision therein which may be defective or inconsistent with any other provision therein, or to make any other changes to the provisions thereof or to add other provisions with respect to matters and questions arising under the Indenture, so long as such other changes or additions do not adversely affect the interests of the Holders of Indenture Securities of any series or Tranche in any material respect. Without limiting the generality of the foregoing, if the Trust Indenture Act is amended after the date of the Original Indenture in such a way as to require changes to the Indenture or the incorporation therein of additional provisions or so as to permit changes to, or the elimination of, provisions which, at the date of the Original Indenture or at any time thereafter, were required by the Trust Indenture Act to be contained in the Indenture, the Indenture will be deemed to have been amended so as to conform to such amendment or to effect such changes or elimination, and Avista Corp. and the Trustee may, without the consent of any Holders of Indenture Securities, enter into one or more supplemental indentures to evidence or effect such amendment. (See Section 1101.) 13

Modifications Requiring Consent Except as provided above, the consent of the Holders of a majority in aggregate principal amount of the Indenture Securities of all series then Outstanding, considered as one class is required for the purpose of adding any provisions to, or changing in any manner, or eliminating any of the provisions of, the Indenture pursuant to one or more supplemental indentures; provided, however, that if less than all of the series of Indenture Securities Outstanding are directly affected by a proposed supplemental indenture, then the consent only of the Holders of a majority in aggregate principal amount of Outstanding Indenture Securities of all series so directly affected, considered as one class, will be required; provided, further, that if the Indenture Securities of any series have been issued in more than one Tranche and if the proposed supplemental indenture directly affects the rights of the Holders of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Indenture Securities of all Tranches so directly affected, considered as one class, will be required; and provided, further, that no such supplemental indenture may: (a) change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Indenture Security other than pursuant to the terms thereof, or reduce the principal amount thereof or the rate of interest thereon (or the amount of any installment of interest thereon) or change the method of calculating such rate or reduce any premium payable upon the redemption thereof, or reduce the amount of the principal of any Discount Security that would be due and payable upon a declaration of acceleration of Maturity or change the coin or currency (or other property) in which any Indenture Security or any premium or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity of any Indenture Security (or, in the case of redemption, on or after the redemption date) without, in any such case, the consent of the Holder of such Indenture Security; (b) reduce the percentage in principal amount of the Outstanding Indenture Securities of any series, or any Tranche thereof, the consent of the Holders of which is required for any such supplemental indenture, or the consent of the Holders of which is required for any waiver of compliance with any provision of the Indenture or of any default thereunder and its consequences, or reduce the requirements for quorum or voting, without, in any such case, the consent of the Holder of each Outstanding Indenture Security of such series or Tranche; or (c) modify certain provisions of the Indenture relating to supplemental indentures, waivers of certain covenants and waivers of past defaults with respect to the Indenture Securities of any series, or any Tranche thereof, without the consent of the Holder of each Outstanding Indenture Security of such series or Tranche. A supplemental indenture which changes or eliminates any covenant or other provision of the Indenture which has expressly been included solely for the benefit of the Holders of, or which is to remain in effect only so long as there shall be Outstanding, Indenture Securities of one or more specified series, or one or more Tranches thereof, or modifies the rights of the Holders of Indenture Securities of such series or Tranches with respect to such covenant or other provision, will be deemed not to affect the rights under the Indenture of the Holders of the Indenture Securities of any other series or Tranche. If the supplemental indenture or other document establishing any series or Tranche of Indenture Securities so provides, and as specified in the applicable prospectus supplement and/or pricing supplement, the Holders of such Indenture Securities will be deemed to have consented, by virtue of their purchase of 14

such Indenture Securities, to a supplemental indenture containing the additions, changes or eliminations to or from the Indenture which are specified in such supplemental indenture or other document, no Act of such Holders will be required to evidence such consent and such consent may be counted in the determination of whether the Holders of the requisite principal amount of Indenture Securities have consented to such supplemental indenture. (See Section 1102.) DUTIES OF THE TRUSTEE; RESIGNATION; REMOVAL The Trustee will have, and will be subject to, all the duties and responsibilities specified with respect to an indenture trustee under the Trust Indenture Act. Subject to such provisions, the Trustee will be under no obligation to exercise any of the powers vested in it by the Indenture at the request of any Holder of Indenture Securities, unless such Holder offers it reasonable indemnity against the costs, expenses and liabilities which might be incurred thereby. The Trustee will not be required to expend or risk its own funds or otherwise incur personal financial liability in the performance of its duties if the Trustee reasonably believes that repayment or adequate indemnity is not reasonably assured to it. (See Sections 801 and 803.) The Trustee may resign at any time with respect to the Indenture Securities of one or more series by giving written notice thereof to Avista Corp. or may be removed at any time with respect to the Indenture Securities of one or more series by Act of the Holders of a majority in principal amount of the Outstanding Indenture Securities of such series delivered to the Trustee and Avista Corp. No resignation or removal of the Trustee and no appointment of a successor trustee will become effective until the acceptance of appointment by a successor trustee in accordance with the requirements of the Indenture. So long as no Event of Default or event which, after notice or lapse of time, or both, would become an Event of Default has occurred and is continuing, if Avista Corp. has delivered to the Trustee with respect to one or more series a resolution of its Board of Directors appointing a successor trustee with respect to that or those series and such successor has accepted such appointment in accordance with the terms of the Indenture, the Trustee with respect to that or those series will be deemed to have resigned and the successor will be deemed to have been appointed as trustee in accordance with the Indenture. (See Section 810.) EVIDENCE OF COMPLIANCE Compliance with the Indenture provisions is evidenced by written statements of Avista Corp. officers or persons selected or paid by Avista Corp. In certain cases, Avista Corp. must furnish opinions of counsel and certifications of an engineer, appraiser or other expert (who in some cases must be independent). In addition, the Indenture requires that Avista Corp. give the Trustee, not less than annually, a brief statement as to Avista Corp.'s compliance with the conditions and covenants under the Indenture. GOVERNING LAW The Indenture and the Indenture Securities will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture of 1939, as amended, shall be applicable. 15

PLAN OF DISTRIBUTION Avista Corp. may sell the Debt Securities in any of four ways: (a) directly to a limited number of institutional purchasers or to a single purchaser, (b) through agents, (c) through underwriters or (d) through dealers. The applicable prospectus supplement relating to each series of Debt Securities will set forth the terms of the offering of such Debt Securities, including the name or names of any such agents, underwriters or dealers, the purchase price of such Debt Securities and the net proceeds to Avista Corp. from such sale, any underwriting discounts and other items constituting underwriters' compensation, the initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time. If Avista Corp. uses underwriters to sell Debt Securities, the underwriters will acquire such Debt Securities for their own account and may resell them in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Unless otherwise set forth in the prospectus supplement relating to a series of Debt Securities, the obligations of any underwriter or underwriters to purchase such Debt Securities will be subject to certain conditions precedent, and such underwriter or underwriters will be obligated to purchase all of such Debt Securities if any are purchased, except that, in certain cases involving a default by one or more underwriters, less than all of such Debt Securities may be purchased. If an agent of Avista Corp. is used in any sale of a series of Debt Securities, any commissions payable by Avista Corp. to such agent will be set forth in the applicable prospectus supplement relating to such Debt Securities. Unless otherwise indicated in the applicable prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment. Any underwriters, dealers or agents participating in the distribution of the Debt Securities may be deemed to be underwriters, and any discounts or commissions received by them on the sale or resale of Debt Securities may be deemed to be underwriting discounts and commissions, under the Securities Act. Agents, underwriters and dealers may be entitled under agreements entered into with Avista Corp. to indemnification by Avista Corp. against certain liabilities, including liabilities under the Securities Act. Unless otherwise provided in the applicable prospectus supplement relating to a series of Debt Securities, Avista Corp. does not intend to apply for the listing of the Notes on a national securities exchange, but has been advised by the agents that they intend to make a market in the Notes, as permitted by applicable laws and regulations. The agents are not obligated to do so, however, and the agents may discontinue making a market at any time without notice. No assurance can be given as to the liquidity of any trading market for the Notes. The agents and/or certain of their affiliates may engage in transactions with and perform services for Avista Corp. and certain of its affiliates in the ordinary course of business. LEGAL MATTERS The validity of the Debt Securities and certain other matters of New York law and matters of federal securities law will be passed upon for Avista Corp. by Thelen Reid & Priest LLP, New York, New York, counsel to Avista Corp. The authorization of the Debt Securities by the Company and certain other matters 16

of Washington law, as well as the authorization of the Debt Securities by the public utility regulatory commissions under Washington, Idaho, Montana, Oregon and California law, will be passed upon for Avista Corp. by Paine, Hamblen, Coffin, Brooke & Miller LLP, Spokane, Washington, counsel for Avista Corp. The validity of the Debt Securities will be passed upon for any underwriters or agents by Sullivan & Cromwell, New York, New York. In giving their opinions Thelen Reid & Priest LLP and Sullivan & Cromwell may assume the conclusions of Washington, California, Idaho, Montana and Oregon law set forth in the opinion of Paine, Hamblen, Coffin, Brooke & Miller LLP. EXPERTS The financial statements and the related financial statement schedules incorporated in this Prospectus by reference from Avista Corp.'s most recent Annual Report on Form 10-K have been audited by Deloitte & Touche LLP, independent auditors, as stated in their report, which is incorporated herein by reference, and have been so incorporated in reliance upon the report of such firm given upon their authority as experts in accounting and auditing. 17

INDEMNIFICATION OF DIRECTORS AND OFFICERS. Article Seventh of the Registrant's Restated Articles of Incorporation ("Articles") provides, in part, as follows: "The Corporation shall, to the full extent permitted by applicable law, as from time to time in effect, indemnify any person made a party to, or otherwise involved in, any proceeding by reason of the fact that he or she is or was a director of the Corporation against judgments, penalties, fines, settlements and reasonable expenses actually incurred by him or her in connection with any such proceeding. The Corporation shall pay any reasonable expenses incurred by a director in connection with any such proceeding in advance of the final determination thereof upon receipt from such director of such undertakings for repayment as may be required by applicable law and a written affirmation by such director that he or she has met the standard of conduct necessary for indemnification, but without any prior determination, which would otherwise be required by Washington law, that such standard of conduct has been met. The Corporation may enter into agreements with each director obligating the Corporation to make such indemnification and advances of expenses as are contemplated herein. Notwithstanding the foregoing, the Corporation shall not make any indemnification or advance which is prohibited by applicable law. The rights to indemnity and advancement of expenses granted herein shall continue as to any person who has ceased to be a director and shall inure to the benefit of the heirs, executors and administrators of such a person." The Registrant has entered into indemnification agreements with each director as contemplated in Article Seventh of the Articles. Reference is made to Revised Code of Washington 23B.08.510, which sets forth the extent to which indemnification is permitted under the laws of the State of Washington. Article IX of the Registrant's Bylaws contains an indemnification provision similar to that contained in the Articles and, in addition, provides in part as follows: II-1

"SECTION 2. LIABILITY INSURANCE. The Corporation shall have the power to purchase and maintain insurance on behalf of any person who is, or was a director, officer, employee, or agent of the Corporation or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, other enterprise, or employee benefit plan against any liability asserted against him and incurred by him in any such capacity or arising out of his status as such, whether or not the Corporation would have the power to indemnify him against such liability under the laws of the State of Washington." Insurance is maintained on a regular basis (and not specifically in connection with this offering) against liabilities arising on the part of directors and officers out of their performance in such capacities or arising on the part of the Registrant out of its foregoing indemnification provisions, subject to certain exclusions and to the policy limits. ITEM 16. EXHIBITS. Reference is made to the Exhibit Index on p. II-5 hereof. ITEM 17. UNDERTAKINGS. 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: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the "Securities Act"); (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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and (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 this registration statement; provided, however, that paragraphs (1)(i) and (1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic 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, as amended (the "Exchange Act") that are incorporated by reference in this registration statement. II-2

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered herein, 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 which remain unsold at the termination of the offering. (4) That, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; (5) That, for purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective. (6) That, for the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities 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 against the Registrant by such director, officer or controlling person in connection with the securities being registered, such 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 Securities Act and will be governed by the final adjudication of such issue. II-3

POWER OF ATTORNEY The Registrant hereby appoints each Agent for Service named in this Registration Statement as its attorney-in-fact to sign in their name and behalf, and to file with the Securities and Exchange Commission any and all amendments, including post-effective amendments, to this Registration Statement, and each director and/or officer of the Registrant whose signature appears below hereby appoints each such Agent for Service as his attorney-in-fact with like authority to sign in his name and behalf, in any and all capacities stated below, and to file with the Securities and Exchange Commission, any and all such amendments.

          forth in this Agreement.

                    Subject to the terms and conditions stated herein and
          to the reservation by the Company of the right to sell Securities
          directly on its own behalf, the Company hereby (i) appoints each
          Agent as an agent of the Company for the purpose of soliciting
          and receiving offers to purchase Securities from the Company
          pursuant to Section 2(a) hereof and (ii) agrees that, except as
          otherwise contemplated herein, whenever it determines to sell
          Securities directly to any Agent as principal, it will enter into
          a separate agreement, substantially in the form of Annex I hereto
          (each a "Terms Agreement"), relating to such sale in accordance
          with Section 2(b) hereof.

                    The Securities will be issued as a series under the

          supplemented by an Officer's Certificate dated         , 1999
          (said Indenture, as so supplemented and as it may be amended and

               supplemented (including by any supplement to the Prospectus
               that sets forth only the terms of a particular tranche of

               with Section 4(a) hereof) in relation to the Securities sold
               pursuant to this Agreement, in the form filed with the
               Commission pursuant to Rule 424(b) under the Act and in
               accordance with Section 4(a) hereof, including any documents
               incorporated by reference therein as of the date of such
               filing) and (iv) no prospectus supplement to the Basic
               Prospectus which relates to securities of the Company other

               of the Company is subject, nor will such action result in
               any violation of the provisions of any statute or the
               Restated Articles of Incorporation, as amended, or the
               Bylaws, as amended, of the Company or, to the best of the
               Company's knowledge, information or belief, any order, rule

               the Securities or the consummation by the Company of the
               other transactions contemplated by this Agreement, any Terms
               Agreement or the Indenture, except such as have been, or
               will have been prior to the Commencement Date (as defined in
               Section 3 hereof), obtained under the Act or 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
               solicitation by such Agent of offers to purchase Securities
               from the Company and with purchases of Securities by such
               Agent as principal, as the case may be, and such consents,
               approvals, authorizations, filings or registrations as may
               be required by the Washington Utilities and Transportation
               Commission, the California Public Utilities Commission, the
               Idaho Public Utilities Commission and the Public Utility
               Commission of Oregon, in each case in the manner
               contemplated hereby;

                         (g)  Except as set forth in or contemplated by 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 to which any property
               of the Company or any of its subsidiaries is subject, which,
               if determined adversely to the Company or any of its
               subsidiaries, would individually or in the aggregate have a
               material adverse effect on the consolidated financial
               position, stockholders' equity or results of operations of
               the Company and its subsidiaries, and, to the best of the
               Company's knowledge, no such proceedings are threatened or
               contemplated by governmental authorities or threatened by
               others; and

                         (h)  Immediately after any sale of Securities by
               the Company hereunder or under any Terms Agreement, the
               aggregate amount of Securities which shall have been issued
               and sold by the Company hereunder or under any Terms
               Agreement that shall have been issued and sold pursuant to
               the Registration Statement will not exceed the amount of
               Securities registered under the Registration Statement.

                    2.   (a)  On the basis of the representations and
          warranties, and subject to the terms and conditions herein set
          forth, each of the Agents hereby severally and not jointly
          agrees, as agent of the Company, to use its reasonable best
          efforts to solicit and receive offers to purchase the Securities
          from the Company upon the terms and conditions set forth in the
          Prospectus as amended or supplemented from time to time.

                    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
          Securities; provided that the suspension period shall not
          commence until such time as no Agent shall then hold any
          Securities purchased from the Company as principal.  Upon receipt
          of at least one business day's prior notice from the Company, the
          Agents will forthwith suspend solicitations of offers to purchase
          Securities from the Company until such time as the Company has
          advised the Agents that such solicitation may be resumed.  While
          such solicitation is suspended, the Company shall not be required
          to deliver any opinions, letters or certificates in accordance
          with Sections 4(i), 4(j), 4(k), 4(l) and 4(m); provided, however,
          that if the Registration Statement or the Prospectus is amended
          or supplemented during the period of suspension (other than by an
          amendment or supplement providing solely for a change in the
          interest rates, redemption provisions, amortization schedules or
          maturities offered on the Securities or for a change the Agents
          deem to be immaterial), no Agent shall be required to resume
          soliciting offers to purchase Securities, or shall purchase
          Securities from the Company as principal, until the Company has
          delivered such opinions, letters and certificates as, but for
          such suspension, would have been required by Sections 4(i), 4(j),
          4(k), 4(l) and 4(m); and provided, further, that the Company
          shall not be so required to deliver more than one opinion, letter
          or certificate pursuant to any of Sections 4(i), 4(j), 4(k), 4(l)
          and 4(m) and that no such opinion, letter or certificate shall be
          required to speak as of any date, or to cover any period ending
          on a date, prior to the later of (i) the end of the period
          covered by the Company's latest Annual Report on Form 10-K which
          has been filed with the Commission, or (ii) the end of the latest
          quarterly period with respect to which opinions, letters or
          certificates have previously been delivered to the Agents in
          accordance with such Sections.

                    So long as this Agreement shall remain in effect with
          respect to any Agent, the Company shall not, without the consent
          of such Agent, which consent shall not unreasonably be withheld,
          solicit or accept offers to purchase, or sell, any debt
          securities with a maturity at the time of original issuance of
          nine months to 40 years except pursuant to (i) this Agreement or
          any Terms Agreement, (ii) the Distribution Agreement, dated April
          24, 1998, among The Washington Water Power Company and the agents
          named therein, (iii) a transaction not constituting a public
          offering under the Act and (iv) a firm commitment underwriting
          pursuant to an underwriting agreement that does not provide for a
          continuous offering of debt securities.  However, the Company
          reserves the right to sell, and may solicit and accept offers to
          purchase, Securities directly on its own behalf, and, in the case
          of any such sale not resulting from a solicitation made by any
          Agent, no commission will be payable with respect to such sale.
          These provisions shall not limit Section 4(f) hereof or any
          similar provisions included in any Terms Agreement.

                    Procedural details relating to the issue and delivery
          of Securities, the solicitation of offers to purchase Securities
          and the payment in each case therefor shall be as set forth in
          the Administrative Procedure attached hereto as Annex II as it
          may be amended from time to time by written agreement between the
          Agents and the Company (the "Administrative Procedure").  The
          provisions of the Administrative Procedure shall apply to all
          transactions contemplated hereunder other than those made
          pursuant to a Terms Agreement.  Each Agent and the Company agree
          to perform the respective duties and obligations specifically
          provided to be performed by each of them in the Administrative
          Procedure.  The Company will furnish to the Trustee a copy of the
          Administrative Procedure as from time to time in effect.

                    The Company reserves the right, in its sole discretion,
          to instruct the Agents to suspend at any time after the
          Commencement Date (as defined in Section 3), for any period of
          time or permanently, the solicitation of offers to purchase the
          Securities.  As soon as practicable, but in any event not later
          than one business day in New York City, after receipt of notice
          from the Company, the Agents will suspend solicitation of offers
          to purchase Securities from the Company until such time as the
          Company has advised the Agents that such solicitation may be
          resumed.

                    The Company agrees to pay each Agent a commission, at
          the time of settlement of any sale of a Security by the Company
          as a result of a solicitation made by such Agent, in an amount
          equal to the following applicable percentage of the principal
          amount of such Security sold:
                                                           Commission
                                                         (percentage of
                                                            aggregate
                                                        principal amount
                      Range of Maturities              of Securities sold)
                      -------------------              ------------------


           From 9 months to less than 1 year                 0.125%

           From 1 year to less than 18 months                0.150%

           From 18 months to less than 2 years               0.200%

           From 2 years to less than 3 years                 0.250%

           From 3 years to less than 4 years                 0.350%

           From 4 years to less than 5 years                 0.450%

           From 5 years to less than 6 years                 0.500%

           From 6 years to less than 7 years                 0.550%

           From 7 years to less than 10 years                0.600%

           From 10 years to less than 15 years               0.625%

           From 15 years to less than 20 years               0.700%

           From 20 years to less than 30 years               0.750%

           From 30 years to 40 years                         0.875%

                    (b)  Each sale of Securities to any Agent as principal
          shall be made in accordance with the terms of this Agreement and
          (unless the Company and such Agent shall otherwise agree in
          writing or orally) a Terms Agreement which will provide for the
          sale of such Securities to, and the purchase thereof by, such
          Agent; it being understood that (unless the Company and such
          Agent shall otherwise agree in writing) any such oral agreement
          relating to the sale of Securities to such Agent as principal (i)
          shall be deemed to incorporate all the terms and conditions set
          forth in the form of Terms Agreement attached hereto as Annex I
          and (ii) shall be promptly confirmed in writing.  A Terms
          Agreement may also specify certain provisions relating to the
          reoffering of such Securities by such Agent.  The commitment of
          any Agent to purchase Securities as principal, whether pursuant
          to any Terms Agreement or otherwise, 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.  Each Terms Agreement shall specify
          the principal amount of Securities to be purchased by any Agent
          pursuant thereto, the price to be paid to the Company for such
          Securities, any provisions relating to rights of, and default by,
          underwriters acting together with such Agent in the reoffering of
          the Securities and the time and date and place of delivery of and
          payment for such Securities.  Such Terms Agreement shall also
          specify any requirements for opinions of counsel, accountants'
          letters and officers' certificates pursuant to Section 4 hereof.

                    For each sale of Securities to an Agent as principal
          that is not made pursuant to a Terms Agreement, the procedural
          details relating to the issue and delivery of such Securities and
          payment therefor shall be as set forth in the Administrative
          Procedure and the Company agrees to pay such Agent a commission
          (or grant an equivalent discount) as provided in Section 2(a)
          hereof and in accordance with the schedule set forth therein.

                    Each time and date of delivery of and payment for
          Securities to be purchased by an Agent as principal, whether set
          forth in a Terms Agreement or in accordance with the
          Administrative Procedure, is referred to herein as a "Time of
          Delivery."

                    3.   The documents required to be delivered pursuant to
          Section 6 hereof on the Commencement Date (as defined below)
          shall be delivered to the Agents at the offices of Thelen Reid &
          Priest LLP, 40 West 57th Street, New York, New York, at 11:00
          a.m., New York City time, on the date of this Agreement, which
          date and time of such delivery may be postponed by agreement
          between the Agents and the Company but in no event shall be later
          than the day prior to the date on which solicitation of offers to
          purchase Securities is commenced or on which any Terms Agreement
          is executed by the parties thereto (such time and date being
          referred to herein as the "Commencement Date").

                    4.   The Company covenants and agrees with each Agent:

                    (a)  (i)  To make no amendment or supplement to the
               Registration Statement or the Prospectus (A) prior to the
               Commencement Date to which any Agent shall reasonably
               disapprove by notice to the Company promptly after
               reasonable notice thereof or (B) after the date of any Terms
               Agreement or other agreement by an Agent to purchase
               Securities as principal and prior to the related Time of
               Delivery which shall be reasonably disapproved by notice to
               the Company by any Agent party to such Terms Agreement or so
               purchasing as principal promptly after reasonable notice
               thereof; (ii) to prepare, with respect to any Securities to
               be sold through or to such Agent pursuant to this Agreement,
               a Pricing Supplement with respect to such Securities in a
               form previously approved by such Agent and to file such
               Pricing Supplement pursuant to Rule 424(b)(3) under the Act
               not later than the close of business of the Commission on
               the third business day following the date on which such
               Pricing Supplement is first used; (iii) to make no amendment
               or supplement to the Registration Statement or Prospectus,
               other than any Pricing Supplement, at any time prior to
               having afforded each Agent a reasonable opportunity to
               review and comment thereon; (iv) to file in a timely manner
               all reports and any definitive proxy or information
               statements required to be filed by the Company with the
               Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of
               the Exchange Act for so long as the delivery of a prospectus
               is required in connection with the offering or sale of the
               Securities, and during such period to advise such Agent,
               promptly after the Company received notices thereof, of the
               time when any amendment to the Registration Statement has
               been filed or has become effective or any supplement to the
               Prospectus or any amended Prospectus (other than any Pricing
               Supplement that relates to Securities not purchased through
               or by such Agent) has been filed with the Commission, of the
               issuance by the Commission of any stop order or of any order
               preventing or suspending the use of any prospectus relating
               to the Securities, of the suspension of the qualification of
               the Securities for offering or sale in any jurisdiction, of
               the initiation or threatening of any proceeding for any such
               purpose, or of any request by the Commission for the
               amendment or supplement of the Registration Statement or
               Prospectus or for additional information; (v) in the event
               of the issuance of any such stop order or of any such order
               preventing or suspending the use of any such prospectus or
               suspending any such qualification, to use promptly every
               reasonable effort to obtain its withdrawal; and (vi) to
               notify the Agents promptly of any change in the rating
               assigned by any nationally recognized statistical rating
               organization to any debt securities of the Company
               (including the Securities) of the Company, or the public
               announcement by any nationally recognized statistical rating
               organization that it has under surveillance or review, with
               possible negative implications, its rating of the Securities
               or any such debt securities, or the withdrawal by any
               nationally recognized statistical rating organization of its
               rating of the Securities or any such debt securities.

                         (b)  Promptly from time to time to take such
               action as such Agent may reasonably request to qualify the
               Securities for offering and sale under the securities laws
               of such jurisdictions as may be approved by the Company and
               to comply with such laws so as to permit the continuance of
               sales and dealings therein for as long as may be necessary
               to complete the distribution or sale of the Securities;
               provided, however, that in connection therewith the Company
               shall not be required to qualify as a foreign corporation or
               to file a general consent to service of process in any
               jurisdiction, or to comply with any other requirement
               reasonably deemed by the Company to be unduly burdensome;

                         (c)  To furnish such Agent with copies of the
               Registration Statement and each amendment thereto, and with
               copies of the Prospectus as each time amended or
               supplemented, other than any Pricing Supplement (except as
               provided in the Administrative Procedure), in the form in
               which it is filed with the Commission pursuant to Rule 424
               under the Act, in such quantities as such Agent may
               reasonably request from time to time, and with copies of the
               documents incorporated by reference therein; and, if the
               delivery of a prospectus is required at any time in
               connection with the offering or sale of the Securities
               (including Securities purchased from the Company by such
               Agent as principal) and if at such time any event shall have
               occurred as a result of which the Prospectus as then amended
               or supplemented would include an untrue statement of a
               material fact or omit to state any material fact necessary
               in order to make the statements therein, in the light of the
               circumstances under which they were made when such
               Prospectus is delivered, not misleading, or, if for any
               other reason it shall be necessary at such time to amend or
               supplement the Prospectus or to file under the Exchange Act
               any document incorporated by reference in the Prospectus in
               order to comply with the Act, the Exchange Act or the Trust
               Indenture Act, to notify such agent and request such Agent,
               in its capacity as agent of the Company, to suspend
               solicitation of offers to purchase Securities from the
               Company (and, if so notified, such Agent shall cease such
               solicitations as soon as practicable, but in any event not
               later than one business day later); and if the Company shall
               decide to amend or supplement the Registration Statement or
               the Prospectus as then amended or supplemented, to so advise
               such Agent promptly by telephone (with confirmation in
               writing) and to prepare and cause to be filed promptly with
               the Commission an amendment or supplement to the
               Registration Statement or the Prospectus as then amended or
               supplemented or to file any document under the Exchange Act
               that will correct such statement or omission or effect such
               compliance; provided, however, that, should such event
               relate solely to activities of any Agent, then such Agent
               shall assume the expense of preparing and furnishing any
               such amendment or supplement; and provided, further, that if
               at such time such Agent continues to own Securities
               purchased from the Company by such Agent as principal or
               such Agent is otherwise required to deliver a prospectus in
               respect of transactions in the Securities, the Company shall
               promptly prepare and file with the Commission such an
               amendment or supplement.  For the purposes of this
               subsection (c), the Company shall be entitled to assume that
               a Prospectus shall no longer be required to be delivered
               under the Act from and after the date six months from the
               date of the purchase thereof by an Agent as principal,
               unless it shall have received notice from such Agent to the
               contrary;

                         (d)  To make generally available to its security
               holders as soon as practicable, but in any event not later
               than eighteen months after (i) the effective date of the
               Registration Statement, (ii) the effective date of each
               post-effective amendment to the Registration Statement, and
               (iii) the date of each filing by the Company with the
               Commission of an Annual Report on Form 10-K that is
               incorporated by reference in the Registration Statement, an
               earning statement of the Company and its subsidiaries (which
               need not be audited) complying with Section 11(a) of the Act
               and the rules and regulations of the Commission thereunder
               (including, at the option of the Company, Rule 158);

                         (e)  For the period ending five years from the
               date any Securities are sold by the Company pursuant to an
               offer solicited by such Agent, to furnish to such Agent
               copies of all reports or other communications (financial or
               other) furnished to stockholders, and deliver to such Agent
               (i) as soon as they are available, copies of any reports and
               financial statements furnished to or filed with the
               Commission or any national securities exchange on which any
               class of securities of the Company is listed and (ii) such
               additional information concerning the business and financial
               condition of the Company as such Agent may from time to time
               reasonably request (such financial statements to be on a
               consolidated basis to the extent the accounts of the Company
               and its subsidiaries are consolidated in reports furnished
               to its stockholders generally or to the Commission);

                         (f)  That, from the date of any Terms Agreement
               with such Agent or other agreement by such Agent to purchase
               Securities as principal and continuing to and including the
               earlier of (i) the termination of the trading restrictions
               for the Securities purchased thereunder, as notified to the
               Company by such Agent and (ii) the related Time of Delivery,
               it will not offer, sell, contract to sell or otherwise
               dispose of any debt securities of the Company in a public
               offering which both mature more than nine months after such
               Time of Delivery and are substantially similar to the
               Securities, without the prior written consent of such Agent;

                         (g)  That each acceptance by the Company of an
               offer to purchase Securities hereunder (including any
               purchase by such Agent as principal not pursuant to a Terms
               Agreement), and each execution and delivery by the Company
               of a Terms Agreement with such Agent, shall be deemed to be
               an affirmation to such Agent that the representations and
               warranties of the Company contained in or made pursuant to
               this Agreement are true and correct as of the date of such
               acceptance or of such Terms Agreement, as the case may be,
               as though made at and as of such date, and an undertaking
               that such representations and warranties will be true and
               correct as of the settlement date for the Securities
               relating to such acceptance or as of the Time of Delivery
               relating to such sale, as the case may be, as though made at
               and as of such date (except that such representations and
               warranties shall be deemed to relate to the Registration
               Statement and the Prospectus as amended and supplemented
               relating to such Securities);

                         (h)  That reasonably in advance of each time the
               Registration Statement or the Prospectus shall be amended or
               supplemented (other than by a Pricing Supplement) and each
               time a document filed under the Act or the Exchange Act is
               incorporated by reference into the Prospectus, and each time
               the Company sells Securities to such Agent as principal
               pursuant to a Terms Agreement and such Terms Agreement
               specifies the delivery of an opinion or opinions by Sullivan
               & Cromwell, of New York, New York, counsel to the Agents, as
               a condition to the purchase of Securities pursuant to such
               Terms Agreement, the Company shall furnish to such counsel
               such papers and information as they may reasonably request
               to enable them to furnish to such Agent such opinion or
               opinions referred to in Section 6(c) hereof;

               or inadvisability of such purchase of Securities shall be
               substituted, for purposes of this Section 4(n), for the
               respective judgments referred to therein of an Agent with
               respect to certain matters referred to in such Sections
               6(a), 6(h) and 6(i), and that such Agent shall have no duty

          Company, at any time ("Solicitation Time") to solicit offers to
          purchase the Securities and the obligation of any Agent to
          purchase Securities as principal, pursuant to any Terms Agreement
          or otherwise, shall in each case be subject, in such Agent's

               and each applicable date referred to in Section 4(i) hereof
               that is on or prior to such Solicitation Time or Time of
               Delivery, as the case may be, in form and substance
               satisfactory to such Agent, to the effect set forth in Annex
               III.

                         (e)  Paine, Hamblen, Coffin, Brooke & Miller LLP,
               counsel to the Company, or other counsel to the Company
               satisfactory to such Agent, shall have furnished to such
               Agent their written opinions, dated the Commencement Date
               and each applicable date referred to in Section 4(j) hereof
               that is on or prior to such Solicitation Time or Time of
               Delivery, as the case may be, in form and substance
               satisfactory to such Agent, to the effect set forth in Annex
               IV.

                         In rendering such opinion or opinions, Paine,
               Hamblen, Coffin, Brooke & Miller LLP may rely as to all
               matters governed by New York law and Federal laws relating
               to the issuance and sale of securities upon the opinion of
               Thelen Reid & Priest LLP referred to below.

                         (f)  Thelen Reid & Priest LLP, counsel to the
               Company, or other counsel to the Company satisfactory to
               such Agent, shall have furnished to such Agent their written
               opinions, dated the Commencement Date and each applicable
               date referred to in Section 4(k) hereof that is on or prior
               to such Solicitation Time or Time of Delivery, as the case
               may be, in form and substance satisfactory to such Agent, to
               the effect set forth in Annex V.

                         In rendering such opinion or opinions Thelen Reid
               & Priest LLP may rely, as to the incorporation of the
               Company and as to all other matters governed by Washington,
               California, Idaho, Montana or Oregon law, upon the opinion
               of Paine, Hamblen, Coffin, Brooke & Miller LLP referred to
               above;

                         (g)  Not later than 11:00 a.m., New York City
               time, on the Commencement Date and on each applicable date
               referred to in Section 4(l) hereof that is on or prior to
               such Solicitation Time or Time of Delivery, as the case may
               be, the independent certified public accountants who have
               certified the financial statements of the Company and its
               subsidiaries included or incorporated by reference in the
               Registration Statement shall have furnished to such Agent a
               letter, dated the Commencement Date or such applicable date,
               as the case may be, in form and substance satisfactory to
               such Agent, to the effect set forth in Annex VI hereto;

                         (h)  Except as set forth in or contemplated by the
               Prospectus, as amended or supplemented, (A) since the
               respective dates as of which information is given in the
               Prospectus, as amended or supplemented, there has not been
               any material adverse change in the condition of the Company
               and its subsidiaries as a whole, financial or otherwise, (B)
               since such dates there has not been any transaction entered
               into by the Company or any subsidiary thereof which is
               material to the Company and its subsidiaries as a whole
               other than transactions in the ordinary course of business,
               and (C) neither the Company nor any of its subsidiaries has
               any contingent obligation which is material to the Company
               and its subsidiaries as a whole, and the effect of which, in
               any such case, is in the reasonable judgment of such Agent,
               so material and adverse as to make it impracticable or
               inadvisable to proceed with the solicitation by such Agent
               of offers to purchase Securities from the Company or the
               purchase by such Agent of Securities from the Company as
               principal, as the case may be, on the terms and in the
               manner contemplated in the Prospectus as amended or
               supplemented;

                         (i)  There shall not have occurred any of the
               following:  (i) a suspension or material limitation in
               trading in securities generally on the New York Stock
               Exchange; (ii) trading of any securities of the Company
               shall have been suspended or limited on any securities
               exchange or in any over-the-counter market; (iii) a general
               moratorium on commercial banking activities in New York
               declared by either Federal or New York State authorities;
               (iv) the outbreak of major hostilities or the material
               escalation of existing hostilities so as to result in major
               hostilities, or the declaration by the United States of a
               national emergency or war, or other national or
               international calamity or crisis; or (v) any downgrading in
               the rating accorded the Company's debt securities by any
               "nationally recognized statistical rating organization" (as
               that term is defined by the Commission for purposes of Rule
               436(g)(2) under the Act) or the placing by any such
               organization of the Company's outstanding debt securities or
               preferred stock on what is commonly termed a "watch list"
               for possible downgrading; provided, however, that in the
               case of any event described in clause (iv) or clause (v)
               above, the effect of such event, in the reasonable judgment
               of such Agent, shall make it impracticable or inadvisable to
               proceed with the solicitation of offers to purchase
               Securities, the purchase of Securities from the Company as
               principal, pursuant to the applicable Terms Agreement or
               otherwise, or the enforcement of contracts for the sale of
               Securities, as the case may be, on the terms and in the
               manner contemplated in the Prospectus as amended or
               supplemented; and

                         (j)  The Company shall have furnished or caused to
               be furnished to such Agent certificates of officers of the
               Company dated the Commencement Date and each applicable date
               referred to in Section 4(m) hereof that is on or prior to
               such Solicitation Time or Time of Delivery, as the case may
               be, in such form and executed by such officers of the
               Company as shall be satisfactory to such Agent, as to the
               accuracy of the representations and warranties of the
               Company herein at and as of the Commencement Date or such
               applicable date, as the case may be, as to the performance
               by the Company in all material respects of all of its
               obligations hereunder to be performed at or prior to the
               Commencement Date or such applicable date, as the case may
               be, as to the matters set forth in subsections (a) and (h)
               of this Section 6, and as to such other matters as such
               Agent may reasonably request.

                    7.   The obligation of the Company to sell and deliver
          Securities, pursuant to any Terms Agreement or otherwise, shall
          in each case be subject to the following conditions:

                         (a)  On the Settlement Date for the Securities or
               Time of Delivery, as the case may be, no stop order
               suspending the effectiveness of the Registration Statement
               shall have been issued and no proceedings for that purpose
               shall be pending before, or to the knowledge of the Company
               or the Agent contemplated by, the Commission.

                         (b)  At or before the Settlement Date or Time of
               Delivery, as the case may be, there shall have been issued,
               and there shall be in full force and effect, appropriate
               orders of the Washington Utilities and Transportation
               Commission, the California Public Utilities Commission, the
               Idaho Public Utilities Commission and the Public Utility
               Commission of Oregon permitting the issuance and sale of the
               Securities on the terms herein set forth or contemplated,
               and containing no provision reasonably unacceptable to the
               Company (it being understood that no such order in effect on
               the date of this Agreement contains any such unacceptable
               provision).

                    If any of the conditions specified above in this
          Section shall not have been fulfilled, the Terms Agreement may be
          terminated by the Company without liability on the part of any
          party to any other party, except for the obligation of the
          Company to pay certain expenses to the extent provided for in
          Sections 6(i) and 6(j) hereof and except for any liability under
          Section 8 hereof.

                    8.  (a)  The Company will indemnify and hold harmless
          each Agent against any losses, claims, damages or liabilities,
          joint or several, to which such Agent 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 an untrue statement or alleged untrue statement of a
          material fact contained in any Preliminary Prospectus, the
          Registration Statement, the Prospectus, the Prospectus as amended
          or supplemented or any other prospectus relating to the
          Securities, or any amendment or supplement thereto, 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 such Agent for any legal or other expenses reasonably
          incurred by it in connection with investigating or defending any
          such loss, claim, damage, liability or action; 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, the Registration Statement, the Prospectus, the
          Prospectus as amended or supplemented or any other prospectus
          relating to the Securities, or any such amendment or supplement,
          in reliance upon and in conformity with written information
          furnished to the Company by such Agent specifically for use in
          the preparation thereof; and provided, further, that, the
          indemnity agreement contained in this subsection (a) shall not
          inure to the benefit of any Agent on account of any such losses,
          claims, damages or liabilities (or actions in respect thereof)
          arising from the sale of the Securities by or through such Agent
          to any person if a copy of the Prospectus as it then may be
          amended or supplemented (exclusive of the Incorporated Documents)
          shall not have been given or sent to such person by such Agent
          with or prior to the written confirmation of the sale involved to
          the extent that (i) the Prospectus as so amended or supplemented
          would have cured the defect in such document giving rise to such
          losses, claims, damages or liabilities, (ii) sufficient
          quantities of the Prospectus as so amended or supplemented were
          timely made available to such Agent and (iii) such Agent shall
          not have reasonably objected to such amendment or supplement
          pursuant to Section 4(a) hereof.

                    (b)  Each Agent 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 an
          untrue statement or alleged untrue statement of a material fact
          contained in any Preliminary Prospectus, the Registration
          Statement, the Prospectus, the Prospectus as amended or
          supplemented or any other prospectus relating to the Securities,
          or any amendment or supplement thereto, 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, 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, the Registration Statement, the
          Prospectus, the Prospectus as amended or supplemented or any
          other prospectus relating to the Securities, or any such
          amendment or supplement, in reliance upon and in conformity with
          written information furnished to the Company by such Agent
          specifically for use in the preparation thereof; and will
          reimburse the Company for any legal or other expenses reasonably
          incurred by the Company in connection with investigating or
          defending any such loss, claim, damage, liability or action.

                    (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 therein 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
          expenses of other counsel or any other expenses, in each case
          subsequently incurred by such indemnified party, in connection
          with the defense thereof other than reasonable costs of
          investigation.  In any such proceeding, any indemnified party
          shall have the right to retain its own counsel, but the fees and
          expenses of such counsel shall be at the expense of such
          indemnified party unless (i) the indemnifying party and the
          indemnified party shall have mutually agreed to the retention of
          such counsel or (ii) the named parties to any such proceeding
          (including any impleaded parties) include both the indemnifying
          party and the indemnified party and representation of both
          parties by the same counsel would be inappropriate due to actual
          or potential differing interests between them.

                    (d)  If the indemnification provided for in this
          Section 8 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 Agent on the other from the
          offering of the Securities to which such loss, claim, damage or
          liability (or action in respect thereof) relates and the relative
          fault of the Company on the one hand and the Agent on the other
          in connection with the statements or omissions which resulted in
          such losses, claims, damages or liabilities, as well as any other
          relevant equitable considerations.  The relative benefits
          received by the Company on the one hand and each Agent on the
          other shall be deemed to be in the same proportion as the total
          net proceeds from the sale of Securities (before deducting
          expenses) received by the Company bear to the total commissions
          or discounts received by such Agent in respect thereof.  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 by any
          Agent 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 Agent agree that it
          would not be just and equitable if contribution pursuant to this
          subsection (d) were determined by per capita allocation (even if
          all Agents were treated as one entity for such purpose) 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, except as limited by subsection (c) above, 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), an Agent shall not be required to contribute any
          amount in excess of the amount by which the total public offering
          price at which the Securities purchased by or through it were
          sold exceeds the amount of any damages which such Agent has
          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 the Agents under
          this subsection (d) to contribute are several in proportion to
          the respective purchases made by it or through it to which such
          loss, claim, damage or liability (or action in respect thereof)
          relates and are not joint.

                    (e)  The obligations of the Company under this Section
          8 shall be in addition to any liability which the Company may
          otherwise have and shall extend, upon the same terms and
          conditions, to each person, if any, who controls any Agent within
          the meaning of the Act; and the obligations of each Agent under
          this Section 8 shall be in addition to any liability which such
          Agent may otherwise have and shall extend, upon the same terms
          and conditions, to each director of the Company, to each officer
          of the Company who has signed the Registration Statement and to
          each person, if any, who controls the Company within the meaning
          of the Act.

                    9.  (a)  Each Agent, in soliciting offers to purchase
          Securities from the Company and in performing the other
          obligations of such Agent hereunder (other than in respect of any
          purchase by an Agent as principal pursuant to a Terms Agreement
          or otherwise), is acting solely as agent for the Company and not
          as principal.  Each Agent will make reasonable efforts to assist
          the Company in obtaining performance by each purchaser whose
          offer to purchase Securities from the Company was solicited by
          such Agent and has been accepted by the Company, but such Agent
          shall not have any liability to the Company in the event such
          purchase is not consummated for any reason.

                    (b)  If the Company shall default on its obligation to
          deliver Securities to a purchaser whose offer it has accepted,
          the Company shall (i) hold each Agent harmless against any loss,
          claim or damage arising from or as a result of such default by
          the Company and (ii) notwithstanding such default, pay to the
          Agent that solicited such offer any commission to which it would
          be entitled in connection with such sale.

                    10.  The respective indemnities, agreements, repre-
          sentations, warranties and other statements by any Agent and the
          Company set forth in or made pursuant to this Agreement shall

ANNEX II Avista Corporation Administrative Procedure ------------------------ This Administrative Procedure relates to the Securities defined in the Distribution Agreement, dated , 1999 (the -------- "Distribution Agreement"), between Avista Corporation (the "Company") and [Insert Name Agent], [Insert Name Agent] and [Insert Name Agent] (the "Agents"), to which this Administrative Procedure is attached as Annex II. Defined terms used herein and not defined herein shall have the meanings given such terms in the Distribution Agreement, the Prospectus (as defined therein), as amended or supplemented, or the Indenture referred to below. The procedures to be followed with respect to the settlement of sales of Securities directly by the Company to purchasers solicited by an Agent, as agent, are set forth below. The terms and settlement details related to a purchase of Securities by an Agent, as principal, from the Company will be set forth in a Terms Agreement pursuant to the Distribution Agreement, unless the Company and such Agent otherwise agree as provided in Section 2(b) of the Distribution Agreement, in which case the procedures to be followed in respect of the settlement of such sale will be as set forth below. An Agent, in relation to a purchase of a Security by a purchaser solicited by such Agent, is referred to herein as the "Selling Agent" and, in relation to a purchase of a Security by such Agent as principal other than pursuant to a Terms Agreement, as the "Purchasing Agent." The Securities will be issued under the Company's Indenture, dated as of April 1, 1998, to The Chase Manhattan Bank, as trustee (the "Trustee") as it will be supplemented by an Officer's Certificate dated , 1999 (such Indenture, as so -------- supplemented and as it may be amended and further supplemented, being hereinafter referred to as the "Indenture"). The Chase Manhattan Bank ("Chase") will act as paying agent for the payment of principal and of premium, if any, and interest on the Securities, and will perform in various capacities unless otherwise specified by the Company or agreed by the parties, the other duties specified herein. The Company will advise each Agent in writing of those persons with whom such Agent is to communicate regarding offers to purchase Securities and the related settlement details. Each tranche of the Securities will be represented entirely by either a Global Security (as defined below) delivered to Chase, as agent for The Depository Trust Company ("DTC"), and recorded in the book-entry system maintained by DTC (a "Book- Entry Security") or by a certificate(s) issued as a registered Security or Securities delivered to the holder(s) thereof or a person(s) designated by such holder(s) (a "Certificated Security"). An owner of a Book-Entry Security will not be entitled to receive a certificate representing such a Security except under the limited circumstances described in the Prospectus. An owner of a Certificated Security will not be entitled to become in lieu thereof the owner of a Book-Entry Security. Administrative procedures and specific terms of the offering are explained below. Certificated Securities will be issued in accordance with the administrative procedures set forth in Part I hereof and Book-Entry Securities will be issued in accordance with the administrative procedures set forth in Part II hereof. Administrative responsibilities and record-keeping functions not performed by Chase or DTC will be performed by the Company's Treasurer or its Assistant Treasurer. PART I: ADMINISTRATIVE PROCEDURE FOR CERTIFICATED SECURITIES Posting Rates by Company: ------------------------ The Company and the Agents will discuss from time to time the rates of interest per annum to be borne by and the maturity of Certificated Securities that may be sold as a result of the solicitation of offers by an Agent. The Company may establish interest rates and maturities for an offering period ("posting") which shall, at all times, be within the limitations set forth by the Company's Board of Directors and in the orders of the Washington Utilities and Transportation Commission ("WUTC"), the California Public Utilities Commission ("CPUC"), the Idaho Public Utilities Commission ("IPUC") and the Public Utility Commission of Oregon ("OPUC") applicable to the issuance and sale of the Securities.

Acceptance of Offers by Company: ------------------------------- Each Agent will promptly advise the Company by telephone or other appropriate means of all reasonable offers to purchase Certificated Securities, other than those rejected by such Agent. Each Agent may, in its discretion reasonably exercised, reject any offer received by it in whole or in part. Each Agent also may make offers to the Company to purchase Certificated Securities as a Purchasing Agent. The Company will have the sole right to accept offers to purchase Certificated Securities and may reject any such offer in whole or in part. The Company will promptly notify the Selling Agent or Purchasing Agent, as the case may be, of its acceptance or rejection of an offer to purchase Certificated Securities. If the Company accepts as offer to purchase Certificated Securities, it will confirm such acceptance in writing to the Selling Agent or Purchasing Agent, as the case may be, and Chase. Communication of Sale Information to Company by Selling Agent: ------------------------------------------------------------- After the acceptance of an offer by the Company, the Selling Agent or Purchasing Agent, as the case may be, will communicate the following details of the terms of such offer (the "Sale Information") to the Company by telephone (confirmed in writing) or by facsimile transmission or other acceptable written means: (1) Whether the Security is a Certificated Security or a Book-Entry Security; (2) Principal amount of Certificated Securities to be purchased; (3) Interest rate, interest payment dates, including without limitation all necessary information with respect to Floating Rate Notes, and initial interest payment date; (4) Stated Maturity Date; (5) Issue Price; (6) Selling Agent's commission or Purchasing Agent's discount or commission, as the case may be; (7) Net proceeds to the Company; (8) Settlement Date (Original Issue Date); (9) If a redeemable Certificated Security, such of the following as are applicable: (a) Initial Redemption Date; (b) Initial Redemption Price (% of par); (c) Amount (% of par) that the Redemption Price shall decline (but not below par) ("Reduction Percentage") and the dates on which such Redemption Price shall decline after the Initial Redemption Date; and (d) Redemption Limitation Date.

The Company will arrange to have ten Pricing Supplements filed with the Commission not later than the close of business of the Commission on the third Business Day following the date on which such Pricing Supplement is first used and will supply at least ten copies of such Pricing Supplement to the Selling Agent or Purchasing Agent, as the case may be. In addition, the Company will file as required copies of the Pricing Supplement with the applicable state regulatory authorities concurrently with the filing of the Pricing Supplement with the Commission. Delivery of Confirmation and Prospectus to Purchaser by Selling --------------------------------------------------------------- Agent: ----- The Selling Agent will deliver to the purchaser of a Security a written confirmation of the sale and delivery and payment instructions. In addition, the Selling Agent will deliver to such purchaser or its agent the prospectus as amended or supplemented (including the Pricing Supplement) relating to such Certificated Security prior to or together with the earlier of the delivery to such purchaser or its agent of (a) the confirmation of sale or (b) the Certificated Security. Date of Settlement: ------------------ The receipt by the Company of immediately available funds in payment for a Certificated Security shall constitute "Settlement" with respect to such Certificated Security. All orders accepted by the Company will be settled on a date (the "Settlement Date") which is the third Business Day after the date of acceptance of such offer, unless the Company and the purchaser agree to Settlement (a) on any other Business Day after the acceptance of such offer or (b) with respect to an offer accepted by the Company prior to 10:00 a.m., New York City time, on the date of such acceptance, provided that such day shall be a Business Day. Instruction from Company to Trustee for Preparation of ------------------------------------------------------ Certificated Securities: ----------------------- After receiving the Sale Information from the Selling Agent or Purchasing Agent, as the case may be, the Company will communicate such Sale Information to the Trustee by Company Order by facsimile transmission or other acceptable written means. The Company will instruct the Trustee by Company Order by facsimile transmission or other acceptable written means to authenticate and deliver the Certificated Securities no later than 2:15 p.m., New York City time, on the Settlement Date. Such instruction will be given by the Company prior to 3:00 p.m., New York City time, on the Business Day prior to the Settlement Date unless the Settlement Date is the date of acceptance by the Company of the offer to purchase Certificated Securities in which case such instruction will be given by the Company to the Trustee by 11:00 a.m., New York City time. Preparation and Delivery of Securities by Trustee and Receipt of ---------------------------------------------------------------- Payment Therefor: ---------------- The Trustee will prepare each Certificated Security and appropriate receipts that will serve as the documentary control of the transaction. In the case of a sale of Certificated Securities to a purchaser solicited by an Agent, the Trustee will, by 2:15 p.m., New York City time, on the Settlement Date, deliver the Certificated Securities to the Selling Agent, at the address listed below, for the benefit of the purchaser of such Certificated Securities against delivery by the Selling Agent of a receipt therefor. On the Settlement Date the Selling Agent will deliver payment for such Certificated Securities in immediately available funds to the Company's account at a bank designated by the Company and notified by the Company to the Selling Agent at least three days prior to the Settlement Date in an amount equal to the issue price of the Certificated Securities less the Selling Agent's commission. Any monies received by an Agent from a purchaser of Securities in payment of the purchase price of such Securities from the time the Trustee delivers the Securities to the Selling Agent to the time the Agent delivers payment for such Securities to the Company's account, as provided above, shall be held by such Agent, as agent of the Company. In the case of a sale of Certificated Securities to a Purchasing Agent, the Trustee will, by 2:15 p.m., New York City time, on the Settlement Date, deliver the Certificated Securities to the Purchasing Agent against delivery by the Purchasing Agent of a receipt therefor. On the Settlement Date, the Purchasing Agent will deliver payment for such Certificated Securities in immediately available funds, or otherwise pursuant to the Terms Agreement, to the account of the Company as designated in the preceding paragraph in an amount equal to the issue price of the Certificated Securities less the Purchasing Agent's discount. Failure of Purchaser to Pay Selling Agent: ----------------------------------------- If a purchaser (other than a Purchasing Agent) fails to make payment to the Selling Agent for a Certificated Security, the Selling Agent will promptly notify the Trustee and the Company thereof by telephone (promptly confirmed in writing) or by facsimile transmission or by other acceptable written means. The Selling Agent will immediately return the Certificated Security to the Trustee. Immediately upon receipt of such Certificated Security by the Trustee, the Company will return to the Selling Agent the amount previously paid to the Company in respect of such Certificated Security. The Company will, in addition, reimburse the Selling Agent on an equitable basis for its loss of the use of funds during the period when they were credited to the account of the Company; provided, however, that the Selling Agent shall be entitled to no reimbursement hereunder if funds are returned on the day on which such funds had been previously credited to the account of the Company such that the Selling Agent is afforded a reasonable opportunity to invest such funds at an overnight rate on such day; and provided further that if the Selling Agent is denied the use of such funds due to its failure to return the relevant Certificated Security to the Trustee in a timely manner it shall only be entitled to reimbursement hereunder in an amount equal to the amount that would have been earned on such funds had such funds been on deposit at an overnight rate during the period between their credit to the account of the Company and their reimbursement to the Agent. The Trustee will cancel the Certificated Security in respect of which the failure occurred, make appropriate entries in its records and, unless otherwise instructed by the Company, dispose of the Certificated Security. Delivery of the Certificated Securities: --------------------------------------- Unless otherwise notified by any Agent to the Trustee, the Trustee shall deliver the Certificated Securities in accordance with the procedures set forth above to any Agent (as the case may be) at the following addresses:

Failure to Settle ----------------- If Chase has not entered an SDFS deliver order with respect to a Book-Entry Security pursuant to Settlement Procedure F, the Company may instruct Chase to deliver to DTC, through DTC's Participant Terminal System, as soon as practicable, a withdrawal message instructing DTC to debit such Book-Entry Security to Chase's participant account. DTC will process the withdrawal message, provided that Chase's participant account contains a principal amount of the Global Security representing such Book-Entry Security that is at least equal to the principal amount to be debited. If a withdrawal message is processed with respect to all the Book-Entry Securities represented by a Global Security, Chase will mark such Global Security "canceled", make appropriate entries in Chase's records and send such canceled Global Security to the Company. The CUSIP number assigned to such Global Note shall, in accordance with CUSIP Service Bureau procedures, be canceled and not immediately reassigned. If a withdrawal message is processed with respect to less than the entire principal amount of the Book-Entry Securities represented by a Global Security, Chase will exchange such Global Security for two Global Securities, one of which shall represent the Book- Entry Security or Securities for which a withdrawal message has been processed and shall be canceled immediately after issuance and the other of which shall represent the Book-Entry Security previously represented by the surrendered Global Security with respect to which a withdrawal message has not been processed and shall bear the CUSIP number of the surrendered Global Security. If the purchase price for any Book-Entry Security is not timely paid to the Participants with respect to such Book- Entry Security 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 Agent for such Book-Entry Security may enter SDFS deliver orders through DTC's Participant Terminal System debiting such Book-Entry Security to such Participant's account and crediting such Book- Entry Security to such Agent's participant account and then debiting such Book-Entry Security to such Agent's participant account and crediting such Book-Entry Security to Chase's participant account, and shall notify the Company and Chase thereof. Thereafter, Chase will (i) immediately notify the Company of such order, once Chase has confirmed that such Book- Entry Security has been credited to its participant account, and the Company shall transfer to such Agent funds available for immediate use in an amount equal to the price of such Book-Entry Security which was previously credited to the account of the Company in accordance with Settlement Procedure I, and (ii) deliver the withdrawal message and take the related actions described in the preceding paragraph. If such failure shall have occurred for any reason other than default by the Agent in the performance of its obligations hereunder or under the Distribution Agreement, the Company will reimburse the Agent on an equitable basis for its loss of the use of funds during the period when they were credited to the account of the Company; provided, however, that the Selling Agent shall be entitled to no reimbursement hereunder if funds are returned on the day on which such funds had been previously credited to the account of the Company such that the Selling Agent is afforded a reasonable opportunity to invest such funds at an overnight rate on such day; and provided further that if the Selling Agent is denied the use of such funds due to its failure to return the relevant Security to the Trustee in a timely manner it shall only be entitled to reimbursement hereunder in an amount equal to the amount that would have been earned on such funds had such funds been on deposit at an overnight rate during the period between their credit to the account of the Company and their reimbursement to the Agent. Notwithstanding the foregoing, upon any failure to settle with respect to a Book-Entry Security, 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 Securities to have been represented by a Global Security, the Trustee will provide, in accordance with Settlement Procedure D for the authentication and issuance of a Global Security representing the other Book-Entry Securities to have been represented by such Global Security and will make appropriate entries in its records.

Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include: (a) a statement that each individual signing such certificate or opinion has read such covenant or condition and the definitions herein relating thereto; (b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based; (c) a statement that, in the opinion of each such individual, such individual has made such examination or investigation as is necessary to enable such individual to express an informed opinion as to whether or not such covenant or condition has been complied with; and (d) a statement as to whether, in the opinion of each such individual, such condition or covenant has been complied with. -9- SECTION 103. Content and Form of Documents Delivered to Trustee. (a) Any Officer's Certificate may be based (without further examination or investigation), insofar as it relates to or is dependent upon legal matters, upon an opinion of, or representations by, counsel, unless, in any case, such officer has actual knowledge that the certificate or opinion or representations with respect to the matters upon which such Officer's Certificate may be based as aforesaid are erroneous. Any Opinion of Counsel may be based (without further examination or investigation), insofar as it relates to or is dependent upon factual matters, information with respect to which is in the possession of the Company, upon a certificate of, or representations by, an officer or officers of the Company, unless such counsel has actual knowledge that the certificate or opinion or representations with respect to the matters upon which his opinion may be based as aforesaid are erroneous. In addition, any Opinion of Counsel may be based (without further examination or investigation), insofar as it relates to or is dependent upon matters covered in an Opinion of Counsel rendered by other counsel, upon such other Opinion of Counsel, unless such counsel has actual knowledge that the Opinion of Counsel rendered by such other counsel with respect to the matters upon which his Opinion of Counsel may be based as aforesaid are erroneous. If, in order to render any Opinion of Counsel provided for herein, the signer thereof shall deem it necessary that additional facts or matters be stated in any Officer's Certificate provided for herein, then such certificate may state all such additional facts or matters as the signer of such Opinion of Counsel may request. (b) In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument. (c) Whenever, subsequent to the receipt by the Trustee of any Board Resolution, Officer's Certificate, Opinion of Counsel or other document or instrument, a clerical, typographical or other inadvertent or unintentional error or omission shall be discovered therein, a new document or instrument may be substituted therefor in corrected form with the same force and effect as if originally filed in the corrected form and, irrespective of the date or dates of the actual execution and/or delivery thereof, such substitute document or instrument shall be deemed to have been executed and/or delivered as of the date or dates required with respect to the document or instrument for which it is substituted. Anything in this Indenture to the contrary notwithstanding, if any such corrective document or instrument indicates that action has been taken by or at the request of the Company which could not have been taken had the original document or instrument not contained such error or omission, the action so taken shall

-10- SECTION 104 not be invalidated or otherwise rendered ineffective but shall be and remain in full force and effect, except to the extent that such action was a result of willful misconduct or bad faith. Without limiting the generality of the foregoing, any Securities issued under the authority of such defective document or instrument shall nevertheless be the valid obligations of the Company entitled to the benefits provided by this Indenture equally and ratably with all other Outstanding Securities, except as aforesaid. SECTION 104. Acts of Holders. (a) Any request, demand, authorization, direction, notice, consent, election, waiver or other action provided by this Indenture to be made, given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing or, alternatively, may be embodied in and evidenced by the record of Holders voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders duly called and held in accordance with the provisions of Article Twelve, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments and so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 801) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. The record of any meeting of Holders shall be proved in the manner provided in Section 1206. (b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof or may be proved in any other manner which the Trustee and the Company deem sufficient. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. (c) The ownership of Securities, the principal amount (except as otherwise contemplated in clause (y) of the first proviso to the definition of Outstanding) and serial numbers of Securities held by any Person, and the date of holding the same, shall be proved by the Security Register. (d) Any request, demand, authorization, direction, notice, consent, election, waiver or other Act of a Holder shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or

-11- the Company in reliance thereon, whether or not notation of such action is made upon such Security. (e) Until such time as written instruments shall have been delivered to the Trustee with respect to the requisite percentage of principal amount of Securities for the action contemplated by such instruments, any such instrument executed and delivered by or on behalf of a Holder may be revoked with respect to any or all of such Securities by written notice by such Holder or any subsequent Holder, proven in the manner in which such instrument was proven. (f) Securities of any series, or any Tranche thereof, authenticated and delivered after any Act of Holders may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any action taken by such Act of Holders. If the Company shall so determine, new Securities of any series, or any Tranche thereof, so modified as to conform, in the opinion of the Trustee and the Company, to such action may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series or Tranche. (g) The Company may, at its option, by Company Order, fix in advance a record date for the determination of Holders entitled to give any request, demand, authorization, direction, notice, consent, waiver or other Act solicited by the Company, but the Company shall have no obligation to do so; provided, however, that the Company may not fix a record date for the giving or making of any notice, declaration, request or direction referred to in the next sentence. In addition, the Trustee may, at its option, fix in advance a record date for the determination of Holders of Securities of any series entitled to join in the giving or making of any Notice of Default, any declaration of acceleration referred to in Section 702, any request to institute proceedings referred to in Section 707 or any direction referred to in Section 712, in each case with respect to Securities of such series. If any such record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act, or such notice, declaration, request or direction, may be given before or after such record date, but only the Holders of record at the close of business on the record date shall be deemed to be Holders for the purposes of determining (i) whether Holders of the requisite proportion of the Outstanding Securities have authorized or agreed or consented to such Act (and for that purpose the Outstanding Securities shall be computed as of the record date) and/or (ii) which Holders may revoke any such Act (notwithstanding subsection (e) of this Section); and any such Act, given as aforesaid, shall be effective whether or not the Holders which authorized or agreed or consented to such Act remain Holders after such record date and whether or not the Securities held by such Holders remain Outstanding after such record date.

-12- SECTION 105 SECTION 105. Notices, Etc. to Trustee and Company. Any request, demand, authorization, direction, notice, consent, election, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, the Trustee by any Holder or by the Company, or the Company by the Trustee or by any Holder, shall be sufficient for every purpose hereunder (unless otherwise expressly provided herein) if the same shall be in writing and delivered personally to an officer or other responsible employee of the addressee, or transmitted by facsimile transmission, telex or other direct written electronic means to such telephone number or other electronic communications address set forth opposite such parties name below or as the parties hereto shall from time to time designate, or transmitted by registered mail, charges prepaid, to the applicable address set opposite such party's name below or to such other address as either party hereto may from time to time designate: If to the Trustee, to: The Chase Manhattan Bank 450 West 33rd Street - 15th Floor New York, New York 10001 Attention: Global Trust Services Telephone: (212) 270-6000 Facsimile: (212) 946-8158 If to the Company, to: The Washington Water Power Company 1411 East Mission Avenue Spokane, Washington 99202 Attention: Treasurer Telephone: (509) 489-0500 Facsimile: (509) 482-4879 Any communication contemplated herein shall be deemed to have been made, given, furnished and filed if personally delivered, on the date of delivery, if transmitted by facsimile transmission, telex or other direct written electronic means, on the date of transmission, and if transmitted by registered mail, on the date of receipt. SECTION 106. Notice to Holders of Securities; Waiver. Except as otherwise expressly provided herein, where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given, and shall be deemed given, to Holders if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at the address of such Holder as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice.

-13- In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice to Holders by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Any notice required by this Indenture may be waived in writing by the Person entitled to receive such notice, either before or after the event otherwise to be specified therein, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. SECTION 107. Conflict with Trust Indenture Act. If any provision of this Indenture limits, qualifies or conflicts with another provision hereof which is required or deemed to be included in this Indenture by, or is otherwise governed by, any provision of the Trust Indenture Act, such other provision shall control; and if any provision hereof otherwise conflicts with the Trust Indenture Act, the Trust Indenture Act shall control. SECTION 108. Effect of Headings and Table of Contents. The Article and Section headings in this Indenture and the Table of Contents are for convenience only and shall not affect the construction hereof. SECTION 109. Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. SECTION 110. Separability Clause. In case any provision in this Indenture or the Securities shall be held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. -14- SECTION 111 SECTION 111. Benefits of Indenture. Nothing in this Indenture or the Securities, express or implied, shall give to any Person, other than the parties hereto, their successors hereunder and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture. SECTION 112. Governing Law. This Indenture and the Securities shall be governed by and construed in accordance with the law of the State of New York (including without limitation Section 5-1401 of the New York General Obligations Law or any successor to such statute), except to the extent that the Trust Indenture Act shall be applicable. SECTION 113. Legal Holidays. In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities other than a contrary provision in the Securities of any series, or any Tranche thereof, or in the indenture supplemental hereto, Board Resolution or Officer's Certificate which establishes the terms of the Securities of such series or Tranche) payment of interest or principal and premium, if any, need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity, and, if such payment is made or duly provided for on such Business Day, no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be, to such Business Day. ARTICLE TWO Security Forms SECTION 201. Forms Generally. The definitive Securities of each series shall be in substantially the form or forms established in the Officer's Certificate, the indenture supplemental hereto or the Board Resolution establishing such series, in any case with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange or as may, consistently herewith, be determined by the officers executing such Securities, as evidenced by their execution of the Securities.

Unless otherwise specified with respect to a series of Securities pursuant to Section 301(b), any limit upon the aggregate principal amount of a series of Securities may be increased without the consent of any Holders and additional Securities of such series may be authenticated and delivered up to the limit upon the aggregate principal amount authorized with respect to such series as so increased. Anything herein to the contrary notwithstanding, the Trustee shall be under no obligation to authenticate and deliver Securities of any series the terms of which, established as contemplated by this Section, would affect the rights, duties, obligations, liabilities or immunities of the Trustee under this Indenture or otherwise. SECTION 302. Denominations. Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, or any Tranche thereof, the Securities of each series shall be issuable in denominations of One Thousand Dollars ($1,000) and any integral multiple thereof.

Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, or any Tranche thereof, the Securities shall be executed on behalf of the Company by an Authorized Officer, and may have the corporate seal of the Company affixed thereto or reproduced thereon and attested by any other Authorized Officer. The signature of any or all of these officers on the Securities may be manual or facsimile. Securities bearing the manual or facsimile signatures of individuals who were at the time of execution Authorized Officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

-20- SECTION 303 The Trustee shall authenticate and deliver Securities of a series, for original issue, at one time or from time to time in accordance with the Company Order referred to below, upon receipt by the Trustee of: (a) the instrument or instruments establishing the form or forms and terms of such series, as provided in Sections 201 and 301; (b) a Company Order requesting the authentication and delivery of such Securities and, to the extent that the terms of such Securities shall not have been established in an Officer's Certificate, an indenture supplemental hereto or a Board Resolution, all as contemplated by Sections 201 and 301, either (i) establishing such terms or (ii) in the case of Securities of a series subject to a Periodic Offering, specifying procedures, acceptable to the Trustee, by which such terms are to be established (which procedures may provide for authentication and delivery pursuant to oral or electronic instructions from the Company or any agent or agents thereof, which oral instructions are to be promptly confirmed electronically or in writing), in either case in accordance with the instrument or instruments delivered pursuant to clause (a) above; (c) Securities of such series, executed on behalf of the Company by an Authorized Officer; (d) an Opinion of Counsel to the effect that: (i) the form or forms of such Securities have been duly authorized by the Company and have been established in conformity with the provisions of this Indenture; (ii) the terms of such Securities have been duly authorized by the Company and have been established in conformity with the provisions of this Indenture; and (iii) when such Securities shall have been authenticated and delivered by the Trustee and issued and delivered by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, such Securities will constitute valid obligations of the Company, entitled to the benefits provided by this Indenture; provided, however, that, with respect to Securities of a series subject to a Periodic Offering, the Trustee shall be entitled to receive such Opinion of Counsel only once at or prior to the time of the first authentication and delivery of such Securities (provided that such Opinion of Counsel addresses the

-21- authentication and delivery of all Securities of such series) and that, in lieu of the opinions described in clauses (ii) and (iii) above, Counsel may opine that: (x) when the terms of such Securities shall have been established pursuant to a Company Order or Orders or pursuant to such procedures as may be specified from time to time by a Company Order or Orders, all as contemplated by and in accordance with the instrument or instruments delivered pursuant to clause (a) above, such terms will have been duly authorized by the Company and will have been established in conformity with the provisions of this Indenture; and (y) when such Securities shall have been authenticated and delivered by the Trustee in accordance with this Indenture and the Company Order or Orders or the specified procedures referred to in paragraph (x) above and issued and delivered by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, such Securities will constitute valid obligations of the Company, entitled to the benefits provided by this Indenture. With respect to Securities of a series subject to a Periodic Offering, the Trustee may conclusively rely, as to the authorization by the Company of any of such Securities, the forms and terms thereof, the validity thereof and the compliance of the authentication and delivery thereof with the terms and conditions of this Indenture, upon the Opinion or Opinions of Counsel and the certificates and other documents delivered pursuant to this Article at or prior to the time of the first authentication and delivery of Securities of such series until any of such opinions, certificates or other documents have been superseded or revoked or expire by their terms. In connection with the authentication and delivery of Securities of a series subject to a Periodic Offering, the Trustee shall be entitled to assume that the Company's instructions to authenticate and deliver such Securities do not violate any applicable law or any applicable rule, regulation or order of any Governmental Authority having jurisdiction over the Company. If the form of terms of the Securities of any series have been established by or pursuant to a Board Resolution or an Officer's Certificate as permitted by Sections 201 or 301, the Trustee shall not be required to authenticate such Securities if the issuance of such Securities pursuant to this Indenture will affect the Trustee's own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee. Unless otherwise specified as contemplated by Section 301 with respect to any series of Securities, or any Tranche thereof, each Security shall be dated the date of its authentication. Unless otherwise specified as contemplated by Section 301 with respect to any series of Securities, or any Tranche thereof, no Security shall be entitled to any benefit under

-22- SECTION 304 this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee or an Authenticating Agent by manual signature of an authorized officer thereof, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if (a) any Security shall have been authenticated and delivered hereunder to the Company, or any Person acting on its behalf, but shall never have been issued and sold by the Company, (b) the Company shall deliver such Security to the Security Registrar for cancellation or shall cancel such Security and deliver evidence of such cancellation to the Trustee, in each case as provided in Section 309, and (c) the Company, at its election, shall deliver to the Trustee a written statement (which need not comply with Section 102 and need not be accompanied by an Officer's Certificate or an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, then, for all purposes of this Indenture, such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits hereof. SECTION 304. Temporary Securities. Pending the preparation of definitive Securities of any series, or any Tranche thereof, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed, photocopied or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities; provided, however, that temporary Securities need not recite specific redemption, sinking fund, conversion or exchange provisions. Except as otherwise specified as contemplated by Section 301 with respect to the Securities of any series, or any Tranche thereof, after the preparation of definitive Securities of such series or Tranche, the temporary Securities of such series or Tranche shall be exchangeable, without charge to the Holder thereof, for definitive Securities of such series or Tranche upon surrender of such temporary Securities at the office or agency of the Company maintained pursuant to Section 502 in a Place of Payment for such Securities. Upon such surrender of temporary Securities, the Company shall, except as aforesaid, execute and the Trustee shall authenticate and deliver in exchange therefor definitive Securities of the same series and Tranche, of authorized denominations and of like tenor and aggregate principal amount. Until exchanged in full as hereinabove provided, temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and Tranche and of like tenor authenticated and delivered hereunder.

-23- SECTION 305. Registration, Registration of Transfer and Exchange. The Company shall cause to be kept in one of the offices designated pursuant to Section 502, with respect to the Securities of each series, or any Tranche thereof, a register (the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities of such series or Tranche and the registration of transfer thereof. The Company shall designate one Person to maintain the Security Register for the Securities of each series and such Person is referred to herein, with respect to such series, as the "Security Registrar". Anything herein to the contrary notwithstanding, the Company may designate one or more of its offices as an office in which a register with respect to the Securities of one or more series, or any Tranche or Tranches thereof, shall be maintained, and the Company may designate itself the Security Registrar with respect to one or more of such series. The Security Register shall be open for inspection by the Trustee and the Company at all reasonable times. Except as otherwise specified as contemplated by Section 301 with respect to the Securities of any series, or any Tranche thereof, upon surrender for registration of transfer of any Security of such series or Tranche at the office or agency of the Company maintained pursuant to Section 502 in a Place of Payment for such series or Tranche, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series and Tranche, of authorized denominations and of like tenor and aggregate principal amount. Except as otherwise specified as contemplated by Section 301 with respect to the Securities of any series, or any Tranche thereof, any Security of such series or Tranche may be exchanged at the option of the Holder, for one or more new Securities of the same series and Tranche, of authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at any such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. All Securities delivered upon any registration of transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. Every Security surrendered for registration of transfer or for exchange shall (if so required by the Company, the Trustee or the Security Registrar) be duly endorsed or shall be accompanied by a written instrument of transfer in form satisfactory to the Company, the Trustee or the Security Registrar, as the case may be, duly executed by the Holder thereof or his attorney duly authorized in writing.

-24- SECTION 306 Unless otherwise specified as contemplated by Section 301 with respect to Securities of any series, or any Tranche thereof, no service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 406 or 1106 not involving any transfer. The Company shall not be required to execute or to provide for the registration of transfer of or the exchange of (a) Securities of any series, or any Tranche thereof, during a period of fifteen (15) days immediately preceding the date notice is to be given identifying the serial numbers of the Securities of such series or Tranche called for redemption or (b) any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and Tranche, and of like tenor and principal amount and bearing a number not contemporaneously outstanding. If there shall be delivered to the Company and the Trustee (a) evidence to their satisfaction of the ownership of and the destruction, loss or theft of any Security and (b) such security or indemnity as may be reasonably required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security is held by a Person purporting to be the owner of such Security, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and Tranche, and of like tenor and principal amount and bearing a number not contemporaneously outstanding. Notwithstanding the foregoing, in case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, but subject to compliance with the foregoing conditions, instead of issuing a new Security, pay such Security. Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the fees and expenses of the Trustee) connected therewith. Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone other than the Holder of such new Security, and any such new Security shall be

-25- entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of such series duly issued hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. SECTION 307. Payment of Interest; Interest Rights Preserved. Unless otherwise specified as contemplated by Section 301 with respect to the Securities of any series, or any Tranche thereof, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date, including without limitation interest the payment period for which has been extended as specified with respect to such series as contemplated by Section 301 (herein called "Unpaid Interest"), shall forthwith cease to be payable to the Holder on the related Regular Record Date by virtue of having been such Holder, and such Unpaid Interest may be paid by the Company, at its election in each case, as provided in clause (a) or (b) below: (a) The Company may elect to make payment of any Unpaid Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a date (herein called a "Special Record Date") for the payment of such Unpaid Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Unpaid Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Unpaid Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Unpaid Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Unpaid Interest which shall be not more than thirty (30) days and not less than ten (10) days prior to the date of the proposed payment and not less than twenty-five (25) days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall, not less than fifteen (15) days prior to such Special Record Date, cause notice of the proposed payment of such Unpaid Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to

-26- SECTION 308 each Holder of Securities of such series at the address of such Holder as it appears in the Security Register. Notice of the proposed payment of such Unpaid Interest and the Special Record Date therefor having been so mailed, such Unpaid Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date. (b) The Company may make payment of any Unpaid Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. Subject to the foregoing provisions of this Section and Section 305, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. SECTION 308. Persons Deemed Owners. Prior to the due surrender of any Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name any Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and premium, if any, and (subject to Section 307) interest, if any, on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. SECTION 309. Cancellation by Security Registrar. All Securities surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Security Registrar, be delivered to the Security Registrar and, if not theretofore canceled, shall be promptly canceled by the Security Registrar. The Company may at any time deliver to the Security Registrar for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever or which the Company shall not have issued and sold, and all Securities so delivered shall be promptly canceled by the Security Registrar. Unless by a Company Order the Company shall direct that canceled Securities be returned to it, all canceled Securities held by the Security Registrar shall be disposed of in accordance with the Security Registrar's customary procedures, and the Security Registrar shall promptly deliver a certificate of disposition to the Trustee and the Company. The Security Registrar shall promptly deliver evidence of any cancellation of a Security in accordance with this Section 309 to the Trustee and the Company.

-27- SECTION 310 SECTION 310. Computation of Interest. Except as otherwise specified as contemplated by Section 301 for Securities of any series, or any Tranche thereof, interest on the Securities of each series shall be computed on the basis of a three hundred sixty (360) day year consisting of twelve (12) thirty (30) day months and, with respect to any period less than a full calendar month, on the basis of the actual number of days elapsed during such period. SECTION 311. Payment to Be in Proper Currency. In the case of the Securities of any series, or any Tranche thereof, denominated in any currency other than Dollars or in a composite currency (the "Required Currency"), except as otherwise specified with respect to such Securities as contemplated by Section 301, the obligation of the Company to make any payment of the principal thereof, or the premium, if any, or interest, if any, thereon, shall not be discharged or satisfied by any tender by the Company, or recovery by the Trustee, in any currency other than the Required Currency, except to the extent that such tender or recovery shall result in the Trustee timely holding the full amount of the Required Currency then due and payable. If any such tender or recovery is in a currency other than the Required Currency, the Trustee may take such actions as it considers appropriate to exchange such currency for the Required Currency. The costs and risks of any such exchange, including without limitation the risks of delay and exchange rate fluctuation, shall be borne by the Company, the Company shall remain fully liable for any shortfall or delinquency in the full amount of Required Currency then due and payable, and in no circumstances shall the Trustee be liable therefor except in the case of its negligence or willful misconduct. ARTICLE FOUR Redemption of Securities SECTION 401. Applicability of Article. Securities of any series, or any Tranche thereof, which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for Securities of such series or Tranche) in accordance with this Article. SECTION 402. Election to Redeem; Notice to Trustee. The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or an Officer's Certificate. The Company shall, at least forty-five (45) days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date and of the principal

-28- SECTION 403 amount of such Securities to be redeemed. In the case of any redemption of Securities (a) prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture or (b) pursuant to an election of the Company which is subject to a condition specified in the terms of such Securities, the Company shall furnish the Trustee with an Officer's Certificate evidencing compliance with such restriction or condition. SECTION 403. Selection of Securities to Be Redeemed. If less than all the Securities of any series, or any Tranche thereof, are to be redeemed, the particular Securities to be redeemed shall be selected by the Security Registrar from the Outstanding Securities of such series or Tranche not previously called for redemption, by such method as shall be provided for any particular series or Tranche, or, in the absence of any such provision, by such method of random selection as the Security Registrar shall deem fair and appropriate and which may, in any case, provide for the selection for redemption of portions (in any authorized denomination for Securities of such series or Tranche) of the principal amount of Securities of such series or Tranche having a denomination larger than the minimum authorized denomination for Securities of such series or Tranche; provided, however, that if, as indicated in an Officer's Certificate, the Company shall have offered to purchase all or any principal amount of the Securities then Outstanding of any series, or any Tranche thereof, and less than all of such Securities as to which such offer was made shall have been tendered to the Company for such purchase, the Security Registrar, if so directed by Company Order, shall select for redemption all or any principal amount of such Securities which have not been so tendered. The Security Registrar shall promptly notify the Company and the Trustee in writing of the Securities selected for redemption and, in the case of any Securities selected to be redeemed in part, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. SECTION 404. Notice of Redemption. Notice of redemption shall be given in the manner provided in Section 106 to the Holders of the Securities to be redeemed not less than thirty (30) nor more than sixty (60) days prior to the Redemption Date. All notices of redemption shall state: (a) the Redemption Date, (b) the Redemption Price,

-29- SECTION 404 (c) if less than all the Securities of any series or Tranche are to be redeemed, the identification of the particular Securities to be redeemed and the portion of the principal amount of any Security to be redeemed in part, (d) that on the Redemption Date the Redemption Price, together with accrued interest, if any, to the Redemption Date, will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date, (e) the place or places where such Securities are to be surrendered for payment of the Redemption Price and accrued interest, if any, unless it shall have been specified as contemplated by Section 301 with respect to such Securities that such surrender shall not be required, (f) that the redemption is for a sinking or other fund, if such is the case, and (g) such other matters as the Company shall deem desirable or appropriate. With respect to any notice of redemption of Securities at the election of the Company, unless, upon the giving of such notice, such Securities shall be deemed to have been paid in accordance with Section 601, such notice may state that such redemption shall be conditional upon the receipt by the Paying Agent or Agents for such Securities, on or prior to the date fixed for such redemption, of money sufficient to pay the principal of and premium, if any, and interest, if any, on such Securities and that if such money shall not have been so received such notice shall be of no force or effect and the Company shall not be required to redeem such Securities. In the event that such notice of redemption contains such a condition and such money is not so received, the redemption shall not be made and within a reasonable time thereafter notice shall be given, in the manner in which the notice of redemption was given, that such money was not so received and such redemption was not required to be made, and the Paying Agent or Agents for the Securities otherwise to have been redeemed shall promptly return to the Holders thereof any of such Securities which had been surrendered for payment upon such redemption. Notice of redemption of Securities to be redeemed at the election of the Company, and any notice of non-satisfaction of a condition for redemption as aforesaid, shall be given by the Company or, upon Company Request, by the Security Registrar in the name and at the expense of the Company. Notice of mandatory redemption of Securities shall be given by the Security Registrar in the name and at the expense of the Company.

-30- SECTION 405 SECTION 405. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, and the conditions, if any, set forth in such notice having been satisfied, the Securities or portions thereof so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless, in the case of an unconditional notice of redemption, the Company shall default in the payment of the Redemption Price and accrued interest, if any) such Securities or portions thereof, if interest-bearing, shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with such notice, such Security or portion thereof shall be paid by the Company at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, however, that no such surrender shall be a condition to such payment if so specified as contemplated by Section 301 with respect to such Security; and provided, further, that, except as otherwise specified as contemplated by Section 301 with respect to such Security, any installment of interest on any Security the Stated Maturity of which installment is on or prior to the Redemption Date shall be payable to the Holder of such Security, or one or more Predecessor Securities, registered as such at the close of business on the related Regular Record Date according to the terms of such Security and subject to the provisions of Section 307. SECTION 406. Securities Redeemed in Part. Upon the surrender of any Security which is to be redeemed only in part at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company or the Trustee, as the case may be, duly executed by, the Holder thereof or his attorney duly authorized in writing), the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities of the same series and Tranche, of any authorized denomination requested by such Holder and of like tenor and in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. ARTICLE FIVE Covenants SECTION 501. Payment of Securities. The Company shall pay the principal of and premium, if any, and interest, if any, on the Securities of each series in accordance with the terms of such Securities and this Indenture.

-31- SECTION 502 SECTION 502. Maintenance of Office or Agency. The Company shall maintain in each Place of Payment for the Securities of each series, or any Tranche thereof, an office or agency where payment of such Securities shall be made, where the registration of transfer or exchange of such Securities may be effected and where notices and demands to or upon the Company in respect of such Securities and this Indenture may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of each such office or agency and prompt notice to the Holders of any such change in the manner specified in Section 106. If at any time the Company shall fail to maintain any such required office or agency in respect of Securities of any series, or any Tranche thereof, or shall fail to furnish the Trustee with the address thereof, payment of such Securities shall be made, registration of transfer or exchange thereof may be effected and notices and demands in respect thereof may be served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent for all such purposes in any such event. The Company may also from time to time designate one or more other offices or agencies with respect to the Securities of one or more series, or any Tranche thereof, for any or all of the foregoing purposes and may from time to time rescind such designations; provided, however, that, unless otherwise specified as contemplated by Section 301 with respect to the Securities of such series or Tranche, no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency for such purposes in each Place of Payment for such Securities in accordance with the requirements set forth above. The Company shall give prompt written notice to the Trustee, and prompt notice to the Holders in the manner specified in Section 106, of any such designation or rescission and of any change in the location of any such other office or agency. Anything herein to the contrary notwithstanding, any office or agency required by this Section may be maintained at an office of the Company, in which event the Company shall perform all functions to be performed at such office or agency. SECTION 503. Money for Securities Payments to Be Held in Trust. If the Company shall at any time act as its own Paying Agent with respect to the Securities of any series, or any Tranche thereof, it shall, on or before each due date of the principal of and premium, if any, and interest, if any, on any of such Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and premium or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided. The Company shall promptly notify the Trustee of any failure by the Company (or any other obligor on such Securities) to make any payment of principal of or premium, if any, or interest, if any, on such Securities.

-32- Whenever the Company shall have one or more Paying Agents for the Securities of any series, or any Tranche thereof, it shall, on or before each due date of the principal of and premium, if any, and interest, if any, on such Securities, deposit with such Paying Agents sums sufficient (without duplication) to pay the principal and premium or interest so becoming due, such sums to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of any failure by it so to act. The Company shall cause each Paying Agent for the Securities of any series, or any Tranche thereof, other than the Company or the Trustee, to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent shall: (a) hold all sums held by it for the payment of the principal of and premium, if any, or interest, if any, on such Securities in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; (b) give the Trustee notice of any failure by the Company (or any other obligor upon such Securities) to make any payment of principal of or premium, if any, or interest, if any, on such Securities; and (c) at any time during the continuance of any such failure, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent and furnish to the Trustee such information as it possesses regarding the names and addresses of the Persons entitled to such sums. The Company may at any time pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent and, if so stated in a Company Order delivered to the Trustee, in accordance with the provisions of Article Six; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of and premium, if any, or interest, if any, on any Security and remaining unclaimed for two years after such principal and premium, if any, or interest, if any, has become due and payable shall be paid to the Company on Company Request, or, if then held by the Company, shall be discharged from such trust; and, upon such payment or discharge, the Holder of such Security shall, as an unsecured general creditor and not as the Holder of an Outstanding Security, look only to the Company for payment of the amount so due and payable and remaining unpaid, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall

-33- thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such payment to the Company, may at the expense of the Company cause to be mailed, on one occasion only, notice to such Holder that such money remains unclaimed and that, after a date specified therein, which shall not be less than thirty (30) days from the date of such mailing, any unclaimed balance of such money then remaining will be paid to the Company. SECTION 504. Corporate Existence. Subject to the rights of the Company under Article Ten, the Company shall do or cause to be done all things necessary to preserve and keep its corporate existence in full force and effect. SECTION 505. Maintenance of Properties. The Company shall cause (or, with respect to property owned in common with others, make reasonable effort to cause) all its properties used or useful in the conduct of its businesses, considered as a whole, to be maintained and kept in good condition, repair and working order and shall cause (or, with respect to property owned in common with others, make reasonable effort to cause) to be made such repairs, renewals, replacements, betterments and improvements thereof, as, in the judgment of the Company, may be necessary in order that the operation of such properties, considered as a whole, may be conducted in accordance with common industry practice; provided, however, that nothing in this Section shall prevent the Company from discontinuing, or causing the discontinuance of, the operation and maintenance of any of its properties; and provided, further, that nothing in this Section shall prevent the Company from selling, transferring or otherwise disposing of, or causing the sale, transfer or other disposition of, any of its properties. SECTION 506. Waiver of Certain Covenants. The Company may omit in any particular instance to comply with any term, provision or condition set forth in (a) any covenant or restriction specified with respect to the Securities of any one or more series, or any Tranche or Tranches thereof, as contemplated by Section 301 if before the time for such compliance the Holders of a majority in aggregate principal amount of the Outstanding Securities of all series and Tranches with respect to which compliance with such covenant or restriction is to be omitted, considered as one class, shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition; provided, however, that no such waiver shall be effective as to any matters contemplated in clause (a), (b) or (c) in Section 1102 without consent of the Holders specified in such Section; and

-34- SECTION 507 (b) Section 504 or 505 or Article Ten if before the time for such compliance the Holders of a majority in principal amount of Securities Outstanding under this Indenture shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition; but, in either case, no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. SECTION 507. Annual Officer's Certificate as to Compliance. Not later than December 1 in each year, commencing December 1, 1998, the Company shall deliver to the Trustee an Officer's Certificate which need not comply with Section 102, executed by the principal executive officer, the principal financial officer or the principal accounting officer of the Company, as to such officer's knowledge of the Company's compliance with all conditions and covenants under this Indenture, such compliance to be determined without regard to any period of grace or requirement of notice under this Indenture. ARTICLE SIX Satisfaction and Discharge SECTION 601. Satisfaction and Discharge of Securities. Any Security or Securities, or any portion of the principal amount thereof, shall be deemed to have been paid for all purposes of this Indenture, and the entire indebtedness of the Company in respect thereof shall be satisfied and discharged, if there shall have been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust: (a) money in an amount which shall be sufficient, or (b) in the case of a deposit made prior to the Maturity of such Securities or portions thereof, Eligible Obligations, which shall not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, the principal of and the interest on which when due, without any regard to reinvestment thereof, will provide moneys which, together with the money, if any, deposited with or held by the Trustee or such Paying Agent, shall be sufficient, or (c) a combination of (a) or (b) which shall be sufficient,

-35- to pay when due the principal of and premium, if any, and interest, if any, due and to become due on such Securities or portions thereof; provided, however, that in the case of the provision for payment or redemption of less than all the Securities of any series or Tranche, such Securities or portions thereof shall have been selected by the Security Registrar as provided herein and, in the case of a redemption, the notice requisite to the validity of such redemption shall have been given or irrevocable authority shall have been given by the Company to the Trustee to give such notice, under arrangements satisfactory to the Trustee; and provided, further, that the Company shall have delivered to the Trustee and such Paying Agent: (x) if such deposit shall have been made prior to the Maturity of such Securities, a Company Order stating that the money and Eligible Obligations deposited in accordance with this Section shall be held in trust, as provided in Section 603; (y) if Eligible Obligations shall have been deposited, an Opinion of Counsel to the effect that such obligations constitute Eligible Obligations and do not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, and an opinion of an independent public accountant of nationally recognized standing, selected by the Company, to the effect that the other requirements set forth in clause (b) and, if applicable, (c) above have been satisfied; and (z) if such deposit shall have been made prior to the Maturity of such Securities, an Officer's Certificate stating the Company's intention that, upon delivery of such Officer's Certificate, its indebtedness in respect of such Securities or portions thereof will have been satisfied and discharged as contemplated in this Section. Upon the deposit of money or Eligible Obligations, or both, in accordance with this Section, together with the documents required by clauses (x), (y) and (z) above, the Trustee shall, upon Company Request, acknowledge in writing that such Securities or portions thereof are deemed to have been paid for all purposes of this Indenture and that the entire indebtedness of the Company in respect thereof has been satisfied and discharged as contemplated in this Section. In the event that all of the conditions set forth in the preceding paragraph shall have been satisfied in respect of any Securities or portions thereof except that, for any reason, the Officer's Certificate specified in clause (z) (if otherwise required) shall not have been delivered, such Securities or portions thereof shall nevertheless be deemed to have been paid for all purposes of this Indenture, and the Holders of such Securities or portions thereof shall nevertheless be no longer entitled to the benefits provided by this Indenture or of any of the covenants of the Company under Article Five (except the covenants contained in Sections 502 and 503) or any other covenants made in respect of such Securities or portions thereof as contemplated by Section 301, but the indebtedness of the Company in respect of such Securities or portions thereof shall not be deemed to have been satisfied and discharged prior to Maturity

-36- for any other purpose; and, upon Company Request, the Trustee shall acknowledge in writing that such Securities or portions thereof are deemed to have been paid for all purposes of this Indenture. If payment at Stated Maturity of less than all of the Securities of any series, or any Tranche thereof, is to be provided for in the manner and with the effect provided in this Section, the Security Registrar shall select such Securities, or portions of principal amount thereof, in the manner specified by Section 403 for selection for redemption of less than all the Securities of a series or Tranche. In the event that Securities which shall be deemed to have been paid for purposes of this Indenture, and, if such is the case, in respect of which the Company's indebtedness shall have been satisfied and discharged, all as provided in this Section, do not mature and are not to be redeemed within the sixty (60) day period commencing with the date of the deposit of moneys or Eligible Obligations, as aforesaid, the Company shall, as promptly as practicable, give a notice, in the same manner as a notice of redemption with respect to such Securities, to the Holders of such Securities to the effect that such deposit has been made and the effect thereof. Notwithstanding that any Securities shall be deemed to have been paid for purposes of this Indenture, as aforesaid, the obligations of the Company and the Trustee in respect of such Securities under Sections 304, 305, 306, 404, 502, 503, 807 and 814 and this Article shall survive. The Company shall pay, and shall indemnify the Trustee or any Paying Agent with which Eligible Obligations shall have been deposited as provided in this Section against, any tax, fee or other charge imposed on or assessed against such Eligible Obligations or the principal or interest received in respect of such Eligible Obligations, including, but not limited to, any such tax payable by any entity deemed, for tax purposes, to have been created as a result of such deposit. Anything herein to the contrary notwithstanding, (a) if, at any time after a Security would be deemed to have been paid for purposes of this Indenture, and, if such is the case, the Company's indebtedness in respect thereof would be deemed to have been satisfied and discharged, pursuant to this Section (without regard to the provisions of this paragraph), the Trustee or any Paying Agent, as the case may be, (i) shall be required to return the money or Eligible Obligations, or combination thereof, deposited with it as aforesaid to the Company or its representative under any applicable Federal or State bankruptcy, insolvency or other similar law or (ii) are unable to apply any money held by the Trustee as provided in this Section and Section 603 with respect to such Security by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, such Security shall thereupon be deemed retroactively not to have been paid and any satisfaction and discharge of the Company's indebtedness in respect thereof shall retroactively be deemed not to have been effected, and such Security shall be deemed to remain Outstanding and (b) any

-37- satisfaction and discharge of the Company's indebtedness in respect of any Security shall be subject to the provisions of the last paragraph of Section 503. SECTION 602. Satisfaction and Discharge of Indenture. This Indenture shall upon Company Request cease to be of further effect (except as hereinafter expressly provided), and the Trustee, at the expense of the Company, shall execute such instruments as the Company shall reasonably request to evidence and acknowledge the satisfaction and discharge of this Indenture, when: (a) no Securities remain Outstanding hereunder; and (b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; provided, however, that if, in accordance with the last paragraph of Section 601, any Security, previously deemed to have been paid for purposes of this Indenture, shall be deemed retroactively not to have been so paid, this Indenture shall thereupon be deemed retroactively not to have been satisfied and discharged, as aforesaid, and to remain in full force and effect, and the Company shall execute and deliver such instruments as the Trustee shall reasonably request to evidence and acknowledge the same. Notwithstanding the satisfaction and discharge of this Indenture as aforesaid, the obligations of the Company and the Trustee under Sections 304, 305, 306, 404, 502, 503, 807 and 814 and this Article shall survive. Upon satisfaction and discharge of this Indenture as provided in this Section, the Trustee shall turn over to the Company any and all money, securities and other property then held by the Trustee for the benefit of the Holders of the Securities (other than money and Eligible Obligations held by the Trustee pursuant to Section 603) and shall execute and deliver to the Company such instruments as, in the judgment of the Company, shall be necessary, desirable or appropriate to effect or evidence the satisfaction and discharge of this Indenture. SECTION 603. Application of Trust Money. Neither the Eligible Obligations nor the money deposited pursuant to Section 601, nor the principal or interest payments on any such Eligible Obligations, shall be withdrawn or used for any purpose other than, and shall be held in trust for, the payment of the principal of and premium, if any, and interest, if any, on the Securities or portions of principal amount thereof in respect of which such deposit was made, all subject, however, to the provisions of Section 503; provided, however, that any cash received from such principal or interest payments on such Eligible Obligations, if not then needed for such purpose, shall, to the extent practicable and upon Company Request and delivery to the Trustee of the documents referred to in clause (y) in the first paragraph of Section 601, be invested in Eligible Obligations of the type described

-38- SECTION 701 in clause (b) in the first paragraph of Section 601 maturing at such times and in such amounts as shall be sufficient, together with any other moneys and the proceeds of any other Eligible Obligations then held by the Trustee, to pay when due the principal of and premium, if any, and interest, if any, due and to become due on such Securities or portions thereof on and prior to the Maturity thereof, and interest earned from such reinvestment shall be paid over to the Company as received, free and clear of any trust, lien or pledge under this Indenture; and provided, further, that any moneys held in accordance with this Section on the Maturity of all such Securities in excess of the amount required to pay the principal of and premium, if any, and interest, if any, then due on such Securities shall be paid over to the Company free and clear of any trust, lien or pledge under this Indenture; and provided, further, that if an Event of Default shall have occurred and be continuing, moneys to be paid over to the Company pursuant to this Section shall be held until such Event of Default shall have been waived or cured. ARTICLE SEVEN Events of Default; Remedies SECTION 701. Events of Default. "Event of Default", wherever used herein with respect to the Securities of any series, means any of the following events which shall have occurred and be continuing: (a) failure to pay interest, if any, on any Security of such series within sixty (60) days after the same becomes due and payable; provided, however, that no such failure shall constitute an "Event of Default" if the Company shall have made a valid extension of the interest payment period with respect to the Securities of such series if so provided with respect to such series as contemplated by Section 301; or (b) failure to pay the principal of or premium, if any, on any Security of such series within three (3) Business Days after its Maturity; provided, however, that no such failure shall constitute an "Event of Default" if the Company shall have made a valid extension of the Maturity of the Securities of such series if so provided with respect to such series as contemplated by Section 301; or (c) failure to perform or breach of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in the performance of which or breach of which is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely for the benefit of one or more series of Securities other than such series) for a period of ninety (90) days after there has been given, by registered or certified mail, to the Company by the Trustee, or to the Company and the Trustee by the Holders of at least twenty-five per centum (25%) in principal amount of the Outstanding Securities of such series, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice

-39- of Default" hereunder, unless the Trustee, or the Trustee and the Holders of a principal amount of Securities of such series not less than the principal amount of Securities the Holders of which gave such notice, as the case may be, shall agree in writing to an extension of such period prior to its expiration; provided, however, that the Trustee, or the Trustee and the Holders of such principal amount of Securities of such series, as the case may be, shall be deemed to have agreed to an extension of such period if corrective action is initiated by the Company within such period and is being diligently pursued; or (d) a default under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company (including a default with respect to Securities of any series other than such series) or under any mortgage, indenture or other instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company (including this Indenture), whether such indebtedness now exists or shall hereafter be created, which default (1) shall constitute a failure to make any payment in excess of $5,000,000 of the principal of or interest on such indebtedness when due and payable after the expiration of any applicable grace period with respect thereto or (2) shall have resulted in such indebtedness in an amount in excess of $10,000,000 becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such payment having been made, such indebtedness having been discharged, or such acceleration having been rescinded or annulled, as the case may be, within a period of ninety (90) days after there shall have been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least twenty-five per centum (25%) in principal amount of the Outstanding Securities of such series a written notice specifying such default and requiring the Company to cause such payment to be made, such indebtedness to be discharged or such acceleration to be rescinded or annulled, as the case may be, and stating that such notice is a Notice of Default hereunder; or (e) the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (ii) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition by one or more Persons other than the Company seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official for the Company or for any substantial part of its property, or ordering the winding-up or liquidation of its affairs, and any such decree or order for relief or any such other decree or order shall have remained unstayed and in effect for a period of ninety (90) consecutive days; or (f) the commencement by the Company of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent,

-40- SECTION 702 or the consent by it to the entry of a decree or order for relief in respect of the Company in a case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or similar official of the Company or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the authorization of such action by the Board of Directors. SECTION 702. Acceleration of Maturity; Rescission and Annulment. If an Event of Default shall have occurred and be continuing with respect to Securities of any series at the time Outstanding, then in every such case the Trustee or the Holders of not less than thirty-three per centum (33%) in principal amount of the Outstanding Securities of such series may declare the principal amount (or, if any of the Securities of such series are Discount Securities, such portion of the principal amount of such Securities as may be specified in the terms thereof as contemplated by Section 301) of all of the Outstanding Securities of such series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon such declaration such principal amount (or specified amount), together with premium, if any, and accrued interest, if any, thereon, shall become immediately due and payable; provided, however, that if an Event of Default shall have occurred and be continuing with respect to more than one series of Securities, the Trustee or the Holders of not less than thirty-three per centum (33%) in aggregate principal amount of the Outstanding Securities of all such series, considered as one class, may make such declaration of acceleration, and not the Holders of the Securities of any one of such series. At any time after such a declaration of acceleration with respect to Securities of any series shall have been made, but before a judgment or decree for payment of the money due shall have been obtained by the Trustee as provided in this Article, such declaration and its consequences shall, without further act, be deemed to have been rescinded and annulled, if (a) the Company shall have paid or deposited with the Trustee a sum sufficient to pay (i) all overdue interest, if any, on all Securities of such series then Outstanding; (ii) the principal of and premium, if any, on any Securities of such series then Outstanding which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Securities;

-41- (iii) interest upon overdue interest at the rate or rates prescribed therefor in such Securities, to the extent that payment of such interest is lawful; and (iv) all amounts due to the Trustee under Section 807; and (b) all Events of Default with respect to Securities of such series, other than the non-payment of the principal of Securities of such series which shall have become due solely by such declaration of acceleration, shall have been cured or waived as provided in Section 713. No such rescission shall affect any subsequent Event of Default or impair any right consequent thereon. SECTION 703. Collection of Indebtedness and Suits for Enforcement by Trustee. If an Event of Default described in clause (a) or (b) of Section 701 shall have occurred and be continuing, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of the Securities of the series with respect to which such Event of Default shall have occurred, the whole amount then due and payable on such Securities for principal and premium, if any, and interest, if any, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 807. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated. If an Event of Default with respect to Securities of any series shall have occurred and be continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. SECTION 704. Application of Money Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, to the extent permitted by law, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or premium, if any, or interest,

-42- SECTION 705 if any, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: First: To the payment of all amounts due the Trustee under Section 807; Second: To the payment of the whole amount then due and unpaid upon the Outstanding Securities for principal and premium, if any, and interest, if any, in respect of which or for the benefit of which such money has been collected; and in case such proceeds shall be insufficient to pay in full the whole amount so due and unpaid upon such Securities, then to the payment of such principal and interest, if any, thereon without any preference or priority, ratably according to the aggregate amount so due and unpaid, with any balance then remaining to the payment of premium, if any, and, if so specified as contemplated by Section 301 with respect to the Securities of any series, or any Tranche thereof, interest, if any, on overdue premium, if any, and overdue interest, if any, ratably as aforesaid, all to the extent permitted by applicable law; Third: To the payment of the remainder, if any, to the Company or to whomsoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct. SECTION 705. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, (a) to file and prove a claim for the whole amount of principal, premium, if any, and interest, if any, owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for amounts due to the Trustee under Section 807) and of the Holders allowed in such judicial proceeding, and (b) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to

-43- the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amounts due it under Section 807. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 706. Trustee May Enforce Claims without Possession of Securities. All rights of action and claims under this Indenture or on the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been recovered. SECTION 707. Limitation on Suits. No Holder shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: (a) such Holder shall have previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of such series; (b) the Holders of a majority in aggregate principal amount of the Outstanding Securities of all series in respect of which an Event of Default shall have occurred and be continuing, considered as one class, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; (c) such Holder or Holders shall have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; (d) the Trustee for sixty (60) days after its receipt of such notice, request and offer of indemnity shall have failed to institute any such proceeding; and (e) no direction inconsistent with such written request shall have been given to the Trustee during such sixty (60) day period by the Holders of a majority in

-44- aggregate principal amount of the Outstanding Securities of all series in respect of which an Event of Default shall have occurred and be continuing, considered as one class. it being understood and intended that no one or more of the Holders of Securities of any series shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of the Holders of Securities of such series or to obtain or to seek to obtain priority or preference over any other Holders of Securities of such series or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all Holders of Securities of such series. SECTION 708. Unconditional Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and premium, if any, and (subject to Section 307) interest, if any, on such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. SECTION 709. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and such Holder shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and such Holder shall continue as though no such proceeding had been instituted. SECTION 710. Rights and Remedies Cumulative. Except as otherwise provided in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

-45- SECTION 711. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. SECTION 712. Control by Holders of Securities. If an Event of Default shall have occurred and be continuing in respect of a series of Securities, the Holders of a majority in principal amount of the Outstanding Securities of such series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee with respect to the Securities of such series; provided, however, that if an Event of Default shall have occurred and be continuing with respect to more than one series of Securities, the Holders of a majority in aggregate principal amount of the Outstanding Securities of all such series, considered as one class, shall have the right to make such direction, and not the Holders of the Securities of any one of such series; and provided, further, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and could not involve the Trustee in personal liability in circumstances where indemnity would not, in the Trustee's sole discretion, be adequate, and (b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. SECTION 713. Waiver of Past Defaults. The Holders of a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default with respect to such series hereunder and its consequences, except a default (a) in the payment of the principal of or premium, if any, or interest, if any, on any Security of such series, or (b) in respect of a covenant or provision hereof which under Section 1102 cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. Upon any such waiver, such default shall cease to exist, and any and all Events of Default arising therefrom shall be deemed to have been cured, for every purpose of this

-46- Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. SECTION 714. Undertaking for Costs. The Company and the Trustee agree, and each Holder by its acceptance of a Security shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant, all in the manner, to the extent and except as provided in the Trust Indenture Act; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than ten per centum (10%) in aggregate principal amount of the Outstanding Securities of all series in respect of which such suit may be brought, considered as one class, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or premium, if any, or interest, if any, on any Security on or after the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date). SECTION 715. Waiver of Stay or Extension Laws. To the full extent that it may lawfully so agree, the Company shall not at any time set up, claim or otherwise seek to take the benefit or advantage of any stay or extension law, now or hereafter in effect, in order to prevent or hinder the enforcement of this Indenture; and the Company, for itself and all who may claim under it, so far as it or they now or hereafter may lawfully do so, hereby waives the benefit of all such laws. ARTICLE EIGHT The Trustee SECTION 801. Certain Duties and Responsibilities. (a) Except during the continuance of an Event of Default with respect to Securities of any series, (i) the Trustee undertakes to perform, with respect to Securities of such series, such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

-47- (ii) in the absence of bad faith on its part, the Trustee may, with respect to Securities of such series, conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture. (b) In case an Event of Default with respect to Securities of any series shall have occurred and be continuing, the Trustee shall exercise, with respect to Securities of such series, such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

(d) Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section.

-48- SECTION 802 SECTION 802. Notice of Defaults.

-50- capacity, may become the owner or pledgee of Securities and, subject to Sections 808 and 813, may otherwise deal with the Company with the same rights it would have if it were not such Trustee, Authenticating Agent, Paying Agent, Security Registrar or other agent.

"Trustee" for purposes of this Section shall include any predecessor Trustee; provided, however, that the negligence, wilful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder.

-51- SECTION 808. Disqualification; Conflicting Interests. If the Trustee shall have or acquire any conflicting interest within the meaning of the Trust Indenture Act, it shall either eliminate such conflicting interest or resign to the extent, in the manner and with the effect, and subject to the conditions, provided in the Trust Indenture Act and this Indenture. For purposes of Section 310(b)(1) of the Trust Indenture Act and to the extent permitted thereby, the Trustee, in its capacity as trustee in respect of the Securities of any series, shall not be deemed to have a conflicting interest arising from its capacity as trustee in respect of the Securities of any other series. For purposes of clause (i) of the first proviso contained in Section 310(b) of the Trust Indenture Act, the Indenture, dated as of July 1, 1988, between the Company and The Chase Manhattan Bank (formerly known as Chemical Bank), trustee, shall be deemed to be specifically described herein. SECTION 809. Corporate Trustee Required; Eligibility. There shall at all times be a Trustee hereunder which shall be (a) a corporation organized and doing business under the laws of the United States, any State or Territory thereof or the District of Columbia, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least Fifty Million Dollars ($50,000,000) and subject to supervision or examination by Federal, State, Territorial or District of Columbia authority, or (b) if and to the extent permitted by the Commission by rule, regulation or order upon application, a corporation or other Person organized and doing business under the laws of a foreign government, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least Fifty Million Dollars ($50,000,000) or the Dollar equivalent of the applicable foreign currency and subject to supervision or examination by authority of such foreign government or a political subdivision thereof substantially equivalent to supervision or examination applicable to United States institutional trustees, and, in either case, qualified and eligible under this Article and the Trust Indenture Act. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of such supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section or the Trust Indenture Act, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

-52- SECTION 810. Resignation and Removal; Appointment of Successor. (a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 811. (b) The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 811 shall not have been delivered to the Trustee within thirty (30) days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. (c) The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Trustee and to the Company. (d) If at any time: (i) the Trustee shall fail to comply with Section 808 after written request therefor by the Company or by any Holder who has been a bona fide Holder for at least six months, or (ii) the Trustee shall cease to be eligible under Section 809 or Section 310(a) of the Trust Indenture Act and shall fail to resign after written request therefor by the Company or by any such Holder, or (iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (x) the Company by a Board Resolution may remove the Trustee with respect to all Securities or (y) subject to Section 714, any Holder who has been a bona fide Holder for at least six (6) months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause (other than as contemplated in clause (y) in subsection (d) of this Section), with respect to the Securities of one or more series, the Company, by a Board Resolution, shall take prompt steps to appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such

-53- series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 811. If, within one (1) year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 811, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 811, any Holder who has been a bona fide Holder of a Security of such series for at least six (6) months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. (f) So long as no event which is, or after notice or lapse of time, or both, would become, an Event of Default shall have occurred and be continuing, if the Company shall have delivered to the Trustee with respect to the Securities of one or more series (i) a Board Resolution appointing a successor Trustee or Trustees with respect to that or those series, effective as of a date specified therein, and (ii) an instrument of acceptance of such appointment, effective as of such date, by such successor Trustee or Trustees in accordance with Section 811, the Trustee or Trustees with respect to that or those series shall be deemed to have resigned as contemplated in subsection (b) of this Section, the successor Trustee or Trustees shall be deemed to have been appointed pursuant to subsection (e) of this Section and such appointment shall be deemed to have been accepted as contemplated in Section 811, all as of such date, and all other provisions of this Section and Section 811 shall be applicable to such resignation, appointment and acceptance except to the extent inconsistent with this subsection (f). (g) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its corporate trust office. SECTION 811. Acceptance of Appointment by Successor. (a) In case of the appointment hereunder of a successor Trustee with respect to the Securities of all series, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of all sums owed to it, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts

-54- SECTION 812 of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. (b) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of such series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee and (3) shall add to or change any of the provisions of this Indenture as be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee, upon payment of all sums owed to it, shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates. (c) Upon reasonable request of any such successor Trustee, the Company shall execute instruments to more fully and certainly vest in and confirm to such successor Trustee all rights, powers and trusts referred to in subsection (a) or (b) of this Section, as the case may be. (d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. SECTION 812. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or

-55- substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. SECTION 813. Preferential Collection of Claims against Company. If the Trustee shall be or become a creditor of the Company or any other obligor upon the Securities (other than by reason of a relationship described in Section 311(b) of the Trust Indenture Act), the Trustee shall be subject to any and all applicable provisions of the Trust Indenture Act regarding the collection of claims against the Company or such other obligor. For purposes of Section 311(b) of the Trust Indenture Act: (a) the term "cash transaction" means any transaction in which full payment for goods or securities sold is made within seven days after delivery of the goods or securities in currency or in checks or other orders drawn upon banks or bankers and payable upon demand; and (b) the term "self-liquidating paper" means any draft, bill of exchange, acceptance or obligation which is made, drawn, negotiated or incurred by the Company or such obligor for the purpose of financing the purchase, processing, manufacturing, shipment, storage or sale of goods, wares or merchandise and which is secured by documents evidencing title to, possession of, or a lien upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, provided the security is received by the Trustee simultaneously with the creation of the creditor relationship with the Company or such obligor arising from the making, drawing, negotiating or incurring of the draft, bill of exchange, acceptance or obligation. SECTION 814. Appointment of Authenticating Agent. The Trustee may appoint an Authenticating Agent or Agents with respect to the Securities of one or more series, or any Tranche thereof, which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series or Tranche issued upon original issuance, exchange, registration of transfer or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each

-56- SECTION 814 Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States, any State or Territory thereof or the District of Columbia or the Commonwealth of Puerto Rico, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than Fifty Million Dollars ($50,000,000) and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all of the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section. The provisions of Sections 308, 804 and 805 shall be applicable to each Authenticating Agent. If an appointment with respect to the Securities of one or more series, or any Tranche thereof, shall be made pursuant to this Section, the Securities of such series or Tranche

-57- may have endorsed thereon, in addition to the Trustee's certificate of authentication, an alternate certificate of authentication substantially in the following form: This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture. ------------------------ As Trustee By______________________ As Authenticating Agent By______________________ Authorized Officer If all of the Securities of a series may not be originally issued at one time, and if the Trustee does not have an office capable of authenticating Securities upon original issuance located in a Place of Payment where the Company wishes to have Securities of such series authenticated upon original issuance, the Trustee, if so requested by the Company in writing (which writing need not comply with Section 102 and need not be accompanied by an Opinion of Counsel), shall appoint, in accordance with this Section and in accordance with such procedures as shall be acceptable to the Trustee, an Authenticating Agent having an office in a Place of Payment designated by the Company with respect to such series of Securities.

Subject to the provisions of Section 1101, with the consent of the Holders of a majority in aggregate principal amount of the Securities of all series then Outstanding under this Indenture, considered as one class, by Act of said Holders delivered to the Company and the Trustee, the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, this Indenture; provided, however, that if there shall be Securities of more than one series Outstanding hereunder and if a proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Securities of any series shall have been issued in more than one Tranche and if the proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities

-65- of all Tranches so directly affected, considered as one class, shall be required; and provided, further, that no such supplemental indenture shall: (a) change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Security other than pursuant to the terms thereof, or reduce the principal amount thereof or the rate of interest thereon (or the amount of any installment of interest thereon) or change the method of calculating such rate or reduce any premium payable thereon, or reduce the amount of the principal of any Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 702, or change the coin or currency (or other property), in which any Security or premium, if any, or interest, if any, thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Maturity of any Security, without, in any such case, the consent of the Holder of such Security; or (b) reduce the percentage in principal amount of the Outstanding Securities of any series, or any Tranche thereof, the consent of the Holders of which is required for any such supplemental indenture, or the consent of the Holders of which is required for any waiver of compliance with any provision of this Indenture or of any default hereunder and its consequences, or reduce the requirements of Section 1204 for quorum or voting, without, in any such case, the consent of the Holder of each Outstanding Security of such series or Tranche; or (c) modify any of the provisions of this Section, Section 506 or Section 713 with respect to the Securities of any series or any Tranche thereof (except to increase the percentages in principal amount referred to in this Section or such other Sections or to provide that other provisions of this Indenture cannot be modified or waived without the consent of the Holders of all Securities of such series or Tranche) without, in any such case, the consent of the Holder of each Outstanding Security of such series or Tranche; provided, however, that this clause shall not be deemed to require the consent of any Holder with respect to changes in the references to "the Trustee" and concomitant changes in this Section, or the deletion of this proviso, in accordance with the requirements of Sections 811(b) and 1101(g). A supplemental indenture which (x) changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of the Holders of, or which is to remain in effect only so long as there shall be Outstanding, Securities of one or more specified series, or one or more Tranches thereof, or (y) modifies the rights of the Holders of Securities of such series or Tranches with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series or Tranche.

-66- SECTION 1103 It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. Anything in this Indenture to the contrary notwithstanding, if the Officer's Certificate, supplemental indenture or Board Resolution, as the case may be, establishing the Securities of any series or Tranche shall so provide, (a) the Holders of such Securities shall be deemed to have consented to a supplemental indenture containing the additions, changes or eliminations to or from the Indenture which shall be specified in such Officer's Certificate, supplemental indenture or Board Resolution establishing such series or Tranche, (b) no Act of such Holders shall be required to evidence such consent and (c) such consent may be counted in the determination of whether or not the Holders of the requisite principal amount of Securities shall have consented to such supplemental indenture. SECTION 1103. Execution of Supplemental Indentures. In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 801) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee's own rights, duties, immunities or liabilities under this Indenture or otherwise. SECTION 1104. Effect of Supplemental Indentures. Upon the execution and delivery of any supplemental indenture under this Article this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. Any supplemental indenture permitted by this Article may restate this Indenture in its entirety, and, upon the execution and delivery thereof, any such restatement shall supersede this Indenture as theretofore in effect for all purposes. SECTION 1105. Conformity with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act. SECTION 1106. Reference in Securities to Supplemental Indentures. Securities of any series, or any Tranche thereof, authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for

-67- in such supplemental indenture. If the Company shall so determine, new Securities of any series, or any Tranche thereof, so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series or Tranche. SECTION 1107. Modification without Supplemental Indenture. To the extent, if any, that the terms of any particular series of Securities shall have been established in or pursuant to a Board Resolution or an Officer's Certificate pursuant to a supplemental indenture or a Board Resolution as contemplated by Section 301, and not in a supplemental indenture, additions to, changes in or the elimination of any of such terms may be effected by means of a supplemental Board Resolution or a supplemental Officer's Certificate, as the case may be, delivered to, and accepted by, the Trustee; provided, however, that such supplemental Board Resolution or supplemental Officer's Certificate shall not be accepted by the Trustee or otherwise be effective unless all conditions set forth in this Indenture which would be required to be satisfied if such additions, changes or elimination were contained in a supplemental indenture shall have been appropriately satisfied. Upon the acceptance thereof by the Trustee, any such supplemental Board Resolution or supplemental Officer's Certificate shall be deemed to be a "supplemental indenture" for purposes of Section 1104 and 1106. ARTICLE TWELVE Meetings of Holders; Action without Meeting SECTION 1201. Purposes for Which Meetings May Be Called. A meeting of Holders of Securities of one or more, or all, series, or any Tranche or Tranches thereof, may be called at any time and from time to time pursuant to this Article to make, give or take any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be made, given or taken by Holders of Securities of such series or Tranches.

If the Trustee shall have been asked by the Company to call such a meeting, the Company shall determine the time and place for such meeting and may call such meeting by giving notice thereof in the manner provided in subsection (a) of this Section, or shall direct the Trustee, in the name and at the expense of the Company, to give such notice. If the Trustee shall have been asked to call such a meeting by Holders in accordance with this subsection (b), and the Trustee shall not have given the notice of such meeting within twenty-one (21) days after receipt of such request or shall not thereafter proceed to cause the meeting to be held as provided herein, then the Holders of Securities of such series and Tranches, in the principal amount above specified, may determine the time and the place in the Borough of Manhattan, The City of New York, or in such other place as shall be determined or approved by the Company, for such meeting and may call such meeting for such purposes by giving notice thereof as provided in subsection (a) of this Section. (c) Any meeting of Holders of Securities of one or more, or all, series, or any Tranche or Tranches thereof, shall be valid without notice if the Holders of all Outstanding Securities of such series or Tranches are present in person or by proxy and if representatives of the Company and the Trustee are present, or if notice is waived in writing before or after the meeting by the Holders of all Outstanding Securities of such series, or any Tranche or Tranches thereof, or by such of them as are not present at the meeting in person or by proxy, and by the Company and the Trustee. SECTION 1203. Persons Entitled to Vote at Meetings.

The only Persons who shall be entitled to attend any meeting of Holders of Securities of any series or Tranche shall be the Persons entitled to vote at such meeting and their counsel, any representatives of the Trustee and its counsel and any representatives of the Company and its counsel. SECTION 1204. Quorum; Action. The Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of the series and Tranches with respect to which a meeting shall have been called as hereinbefore provided, considered as one class, shall constitute a quorum for a meeting of Holders of Securities of such series and Tranches; provided, however, that if any action is to be taken at such meeting which this Indenture expressly provides may be taken by

-69- the Holders of a specified percentage, which is less than a majority, in principal amount of the Outstanding Securities of such series and Tranches, considered as one class, the Persons entitled to vote such specified percentage in principal amount of the Outstanding Securities of such series and Tranches, considered as one class, shall constitute a quorum. In the absence of a quorum within one hour of the time appointed for any such meeting, the meeting shall, if convened at the request of Holders of Securities of such series and Tranches, be dissolved. In any other case the meeting may be adjourned for such period as may be determined by the chairman of the meeting prior to the adjournment of such meeting. In the absence of a quorum at any such adjourned meeting, such adjourned meeting may be further adjourned for such period as may be determined by the chairman of the meeting prior to the adjournment of such adjourned meeting. Except as provided by Section 1205(e), notice of the reconvening of any meeting adjourned for more than thirty (30) days shall be given as provided in Section 106 not less than ten (10) days prior to the date on which the meeting is scheduled to be reconvened. Notice of the reconvening of an adjourned meeting shall state expressly the percentage, as provided above, of the principal amount of the Outstanding Securities of such series and Tranches which shall constitute a quorum. Except as limited by Section 1102, any resolution presented to a meeting or adjourned meeting duly reconvened at which a quorum is present as aforesaid may be adopted only by the affirmative vote of the Holders of a majority in aggregate principal amount of the Outstanding Securities of the series and Tranches with respect to which such meeting shall have been called, considered as one class; provided, however, that, except as so limited, any resolution with respect to any action which this Indenture expressly provides may be taken by the Holders of a specified percentage, which is less than a majority, in principal amount of the Outstanding Securities of such series and Tranches, considered as one class, may be adopted at a meeting or an adjourned meeting duly reconvened and at which a quorum is present as aforesaid by the affirmative vote of the Holders of such specified percentage in principal amount of the Outstanding Securities of such series and Tranches, considered as one class. Any resolution passed or decision taken at any meeting of Holders of Securities duly held in accordance with this Section shall be binding on all the Holders of Securities of the series and Tranches with respect to which such meeting shall have been held, whether or not present or represented at the meeting. SECTION 1205. Attendance at Meetings; Determination of Voting Rights; Conduct and Adjournment of Meetings. (a) Attendance at meetings of Holders of Securities may be in person or by proxy; and, to the extent permitted by law, any such proxy shall remain in effect and be binding upon any future Holder of the Securities with respect to which it was given unless and until specifically revoked by the Holder or future Holder (except as provided in Section 104(g)) of such Securities before being voted.

-70- SECTION 1206 (b) Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders of Securities in regard to proof of the holding of such Securities and of the appointment of proxies and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise permitted or required by any such regulations and approved by the Company, the holding of Securities shall be proved in the manner specified in Section 104 and the appointment of any proxy shall be proved in the manner specified in Section 104. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in Section 104 or other proof. (c) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders as provided in Section 1202(b), in which case the Company or the Holders of Securities of the series and Tranches calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of all series and Tranches represented at the meeting, considered as one class. (d) At any meeting each Holder or proxy shall be entitled to one vote for each One Thousand Dollars ($1,000) principal amount of Outstanding Securities held or represented by such Holder; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of a Security or proxy. (e) Any meeting duly called pursuant to Section 1202 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of all series and Tranches represented at the meeting, considered as one class; and the meeting may be held as so adjourned without further notice. SECTION 1206. Counting Votes and Recording Action of Meetings. The vote upon any resolution submitted to any meeting of Holders shall be by written ballots on which shall be subscribed the signatures of the Holders or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities, of the series and Tranches with respect to which the meeting shall have been called, held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of Holders shall be

-71- prepared by the secretary of the meeting and there shall be attached to such record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that such notice was given as provided in Section 1202 and, if applicable, Section 1204. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company, and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated. SECTION 1207. Action without Meeting. In lieu of a vote of Holders at a meeting as hereinbefore contemplated in this Article, any request, demand, authorization, direction, notice, consent, waiver or other action may be made, given or taken by Holders by written instruments as provided in Section 104. ARTICLE THIRTEEN Immunity of Incorporators, Stockholders, Officers and Directors SECTION 1301. Liability Solely Corporate. No recourse shall be had for the payment of the principal of or premium, if any, or interest, if any, on any Securities, or any part thereof, or for any claim based thereon or otherwise in respect thereof, or of the indebtedness represented thereby, or upon any obligation, covenant or agreement under this Indenture, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any predecessor or successor corporation (either directly or through the Company or a predecessor or successor corporation), whether by virtue of any constitutional provision, statute or rule of law or by the enforcement of any assessment or penalty or otherwise; it being expressly agreed and understood that this Indenture and all the Securities are solely corporate obligations and that no personal liability whatsoever shall attach to, or be incurred by, any incorporator, stockholder, officer or director, past, present or future, of the Company or of any predecessor or successor corporation, either directly or indirectly through the Company or any predecessor or successor corporation, because of the indebtedness hereby authorized or under or by reason of any of the obligations, covenants or agreements contained in this Indenture or in any of the Securities or to be implied herefrom or therefrom; and such personal liability, if any, is hereby expressly waived and released as a condition of, and as part of the consideration for, the execution and delivery of this Indenture and the issuance of the Securities.

Except as otherwise provided in said Indenture, any such interest not so paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Unpaid Interest to be fixed by the Trustee, notice of which shall be given to Holders of Securities of this series not less than 15 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. Payment of the principal of and premium, if any, on this Security and interest hereon at Maturity shall be made upon presentation of this Security at the Corporate Trust Office of The Chase Manhattan Bank in New York, New York or at such other office or agency as may be designated for such purpose by the Company from time to time. Payment of interest on this Security (other than interest at Maturity) shall be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register, except that (a) if such Person shall be a securities depositary, such payment may be made by such other means in lieu of check, as shall be agreed upon by the Company, the Trustee and such Person and (b) upon the written request of a Holder of not less than $10 million in aggregate principal amount of Securities (as hereinafter defined) of the same series and Tranche delivered to the Company and the Paying Agent at least ten days prior to any Interest Payment Date, payment of interest on such Securities to such Holder on such Interest Payment Date shall be made by wire transfer of immediately available funds to an account maintained within the continental United States specified by such Holder or, if such Holder maintains an account with the entity acting as Paying Agent, by deposit into such account. Payment of the principal of and premium, if any, and interest on this Security, as aforesaid, shall be made in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts. This Security is one of a duly authorized issue of securities of the Company (herein called the "Securities"), issued and issuable in one or more series under and equally secured by an Indenture, dated as of April 1, 1998 (such Indenture as originally executed and delivered and as supplemented or amended from time to time thereafter, together with any constituent instruments establishing the terms of particular Securities, being herein called the "Indenture"), between the Company and The Chase Manhattan Bank, trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of the Securities thereunder and of the terms and conditions upon which the Securities

are, and are to be, authenticated and delivered and secured. The acceptance of this Security shall be deemed to constitute the consent and agreement by the Holder hereof to all terms and provisions of the Indenture. This Security is one of the series designated above. Interest payments on this Security shall be the amount of interest accrued from and including the last date to which interest has been paid or duly provided for, or, if no interest has been paid or duly provided for, from and including the Original Interest Accrual Date, to but excluding the next succeeding Interest Payment Date; provided, however, that if the interest rate on this Security is reset daily or weekly as specified on the face hereof for the Interest Reset Period, interest payments shall be the amount of interest accrued from and including the most recent date to which interest has been paid or duly provided for, or, if no interest has been paid, from the Original Interest Accrual Date, to, but excluding, the Regular Record Date next preceding such Interest Payment Date, except that at Maturity the interest payable shall include interest accrued to but excluding the date of Maturity. Accrued interest on this Security shall be calculated by multiplying the principal amount of this Security by an accrued interest factor. Such accrued interest factor shall be computed by adding the interest factors calculated for each day in the Interest Payment Period for which accrued interest is being calculated. The interest factor (expressed as a decimal calculated to seven decimal places without rounding) for each such day shall be computed by dividing the interest rate applicable to such day by 360 if the Base Rate is the CD Rate, the Commercial Paper Rate, the Federal Funds Rate, LIBOR or the Prime Rate, as indicated above, or by the actual number of days in the year if the Base Rate is the CMT Rate or the Treasury Rate, as indicated above. For purposes of making the foregoing calculation, the interest rate in effect on any Interest Reset Date shall be the applicable rate as reset on such date. Unless otherwise specified above, all percentages resulting from any calculation of the rate of interest hereon shall be rounded, if necessary, to the nearest 1/100,000 of 1% (.0000001), with five one-millionths of a percentage point rounded upward, and all dollar amounts used in or resulting from such calculation shall be rounded to the nearest one-hundredth cent (with .005 of a cent being rounded upward). Except as otherwise provided herein, commencing with the first Interest Reset Date specified above following the Original Interest Accrual Date and thereafter upon each succeeding Interest Reset Date specified above, the rate at which interest on this Security is payable shall be reset daily, weekly, monthly, quarterly, semi-annually or annually as specified above for the Interest Reset Period, and such rate, as so reset, shall be effective as of and for the related Interest Reset Date and for the balance of the related Interest Reset Period to but excluding the next succeeding Interest Reset Date. Unless otherwise specified above, the Interest Reset Dates shall be, if the interest rate on this Security resets daily, each Business Day; if the interest rate on this Security (unless the Base Rate is the Treasury Rate) resets weekly, Wednesday of each week; if the Base Rate specified above is the Treasury Rate and resets weekly, Tuesday of each week (except as provided below under "Determination of Treasury Rate"); if the interest rate on this Security resets monthly, the third Wednesday of each month; if the interest rate on this Security resets quarterly, the third Wednesday of March, June, September and December of each year; if the interest rate on this Security resets semi-annually, the third Wednesday of the two months of each year specified above; and if the interest rate on this Security resets annually, the third Wednesday of the month of each year specified above; provided, however, that the interest rate in effect for the ten days immediately prior to Maturity will be that in effect on the tenth day preceding Maturity. If an Interest Reset Date for this Security would otherwise be a day that is not a Business Day (as hereinafter defined), such Interest Reset Date shall be postponed to the next succeeding Business Day, except that, if the Base Rate specified on the face hereof is LIBOR and such Business Day is in the next succeeding calendar month, such Interest Reset Date shall be the immediately preceding Business Day.

Anything herein to the contrary notwithstanding, the interest rate hereon shall not be greater than the Maximum Interest Rate, if any, or less than the Minimum Interest Rate, if any, specified above. In addition, the interest rate hereon shall in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application. Unless otherwise specified above, interest will be payable, if the interest rate on this Security resets daily, weekly or monthly, on the third Wednesday of each month or on the third Wednesday of March, June, September and December of each year, as specified above; if the interest rate on this Security resets quarterly, on the third Wednesday of March, June, September and December of each year; if the interest rate on this Security resets semi-annually, on the third Wednesday of the two months of each year specified above; and if the interest rate on this Security resets annually, on the third Wednesday of the month of each year specified above (each such day being an "Interest Payment Date"). If any Interest Payment Date other than a Redemption Date or the Stated Maturity would otherwise be a day that is not a Business Day, such Interest Payment Date shall be postponed to the next succeeding Business Day, except that, if the Base Rate specified above is LIBOR and such next succeeding Business Day is in the next succeeding calendar month, such Interest Payment Date shall be the next preceding Business Day. If a Redemption Date or the Stated Maturity shall not be a Business Day, payment of the amounts due on this Security on such date in respect of principal, premium, if any, and/or interest may be made on the next succeeding Business Day; and if payment is made or duly provided for on such Business Day, no interest shall accrue on such amounts for the period from and after such Redemption Date or Stated Maturity, as the case may be, to such Business Day. The Company will appoint, and enter into an agreement with, an agent (the "Calculation Agent") to calculate the interest rates on floating rate Securities (including this Security). Unless otherwise specified above, The Chase Manhattan Bank shall be the Calculation Agent. All determinations of interest rates by the Calculation Agent shall, in the absence of manifest error, be conclusive for all purposes and binding on the Holder hereof. Subject to applicable provisions of law and except as otherwise specified herein, on each Interest Reset Date the rate of interest shall be determined in accordance with the provisions of the applicable heading below. Determination of CD Rate If the Base Rate specified above is the CD Rate, this Security shall bear interest for each Interest Reset Period at an interest rate calculated with reference to the CD Rate, determined as set forth below, and the Spread or Spread Multiplier, if any, and subject to the Maximum Interest Rate, if any, and the Minimum Interest Rate, if any, specified above. The "CD Rate" for each Interest Reset Period shall be determined by the Calculation Agent on the Calculation Date (as hereinafter defined) and shall be (a) the rate (expressed as a percentage per annum) as of the second Business Day prior to the related Interest Reset Date (a "CD Rate Determination Date") for negotiable certificates of deposit having the Index Maturity specified above as published in H.15(519) under the heading "CDs (Secondary Market)", or (b) if such rate is not so published by 9:00 A.M., New York City time, on the Calculation Date, the rate as of such CD Rate Determination Date for negotiable certificates of deposit of the Index Maturity specified above as published in Composite Quotations (as hereinafter defined), or (c) if neither of such rates is published by 3:00 P.M., New York City time, on the Calculation Date, the arithmetic mean of the secondary market offered rates as of 10:00 A.M., New York City time, on such CD Rate Determination Date for certificates of deposit in an amount that is representative of a single transaction at that time with a remaining maturity closest to the Index Maturity specified above of three

leading nonbank dealers in negotiable U.S. dollar certificates of deposit in The City of New York selected by the Calculation Agent, in its discretion (after consultation with the Company); provided, however, that if the dealers selected as aforesaid by the Calculation Agent are not quoting as described in clause (c) above, the CD Rate for such Interest Reset Period shall be the same as the CD Rate for the immediately preceding Interest Reset Period (or, if there was no such previous Interest Reset Period, the rate of interest hereon for such Interest Reset Period shall be the Initial Interest Rate). Determination of CMT Rate If the Base Rate specified above is the CMT Rate, this Security shall bear interest for each Interest Reset Period at a rate calculated with reference to the CMT Rate, determined as set forth below, and the Spread or Spread Multiplier, if any, and subject to the Maximum Interest Rate, if any, and the Minimum Interest Rate, if any, specified above. The "CMT Rate" for each Interest Reset Period shall be determined by the Calculation Agent on the Calculation Date and shall be the rate (expressed as a percentage per annum) displayed on the Designated CMT Telerate Page (as defined below) under the caption "...Treasury Constant Maturities... Federal Reserve Board Release H.15...Mondays Approximately 3:45 p.m." under the column for the Designated CMT Maturity Index (as defined below) for (a)(i) if the Designated CMT Telerate Page is 7055, the second Business Day prior to the related Interest Reset Date (a "CMT Rate Determination Date") or (ii) if the Designated CMT Telerate Page is 7052, the week or the month, as applicable, ended immediately preceding the week in which such CMT Rate Determination Date occurs, or (b) if such rate is no longer displayed on the relevant page, or if not displayed by 3:00 p.m., New York City time on the Calculation Date, the Treasury Constant Maturity rate for the Designated CMT Maturity Index as published in H.15(519), or (c) if such rate is no longer published or, if not published by 3:00 p.m., New York City time, on the Calculation Date, the Treasury Constant Maturity rate for the Designated CMT Maturity Index (or other United States Treasury rate for the Designated CMT Maturity Index) for such CMT Rate Determination Date as may then be published by either the Board of Governors of the Federal Reserve System or the United States Department of the Treasury that the Calculation Agent determines to be comparable to the rate formerly displayed on the Designated CMT Telerate Page and published in H.15(519), or (d) if such information is not provided by 3:00 p.m., New York City time, on the Calculation Date, then the CMT Rate for the CMT Rate Determination Date shall be a yield to maturity, based on the arithmetic mean of the secondary market closing offer side prices as of approximately 3:30 p.m., New York City time, on the CMT Rate Determination Date reported, according to their written records, by three leading primary United States government securities dealers (each, a "Reference Dealer") in The City of New York selected by the Calculation Agent (from five such Reference Dealers selected by the Calculation Agent, in its discretion (after consultation with the Company), and eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest)), for the most recently issued direct noncallable fixed rate obligations of the United States ("Treasury notes") with an original maturity of approximately the Designated CMT Maturity Index and a remaining term to maturity of not less than such Designated CMT Maturity Index minus one year, or (e) if the Calculation Agent cannot obtain three such Treasury notes quotations, a yield to maturity based on the arithmetic mean of the secondary market offer side prices as of approximately 3:30 p.m., New York City time, on the CMT Rate Determination Date of three Reference Dealers in The City of New York (from five such Reference Dealers selected by the Calculation Agent, in its discretion (after consultation with the Company), and eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest)), for Treasury notes with an original maturity of the number of years that is the next highest to the Designated CMT Maturity Index and a remaining term to maturity closest to the Designated CMT Maturity Index and in an amount of at least $100 million, or (f) if three or four (and not five) of such Reference dealers are quoting as described above, the arithmetic mean of the offer prices obtained without the

elimination of either the highest or the lowest of such quotes; provided, however, that if fewer than three Reference Dealers selected by the Calculation Agent are quoting as described above, the CMT Rate for such Interest Reset Period will be the same as the CMT Rate for the immediately preceding Interest Reset Period (or, if there was no such previous Interest Reset Period, the rate of interest hereon for such Interest Reset Period shall be the Initial Interest Rate). For purposes of clause (e) in the first sentence of this paragraph, if two Treasury notes have remaining terms to maturity equally close to the Designated CMT Maturity Index, the quotes for the Treasury note with the shorter remaining term to maturity shall be used. "Designated CMT Maturity Index" shall be the original period to maturity of the U.S. Treasury securities (either 1, 2, 3, 5, 7, 10, 20 or 30 years) specified above with respect to which the CMT Rate will be calculated. If no such maturity is specified above, the Designated CMT Maturity Index shall be 2 years. "Designated CMT Telerate Page" means the display on the Dow Jones Market service (formerly known as the Dow Jones Telerate Service) on the page specified above (or any other page as may replace such page on that service, or any successor service, for the purpose of displaying Treasury Constant Maturities as reported in H.15(519)), for the purpose of displaying Treasury Constant Maturities as reported in H.15(519). If no such page is specified above, the page shall be 7052, for the most recent week. Determination of Commercial Paper Rate If the Base Rate specified above is the Commercial Paper Rate, this Security shall bear interest for each Interest Reset Period at a rate calculated with reference to the Commercial Paper Rate, determined as set forth below, and the Spread or Spread Multiplier, if any, and subject to the Maximum Interest Rate, if any, and the Minimum Interest Rate, if any, specified above. The "Commercial Paper Rate" for each Interest Reset Period shall be determined by the Calculation Agent on the Calculation Date and shall be (a) the Money Market Yield (as hereinafter defined) as of the second Business Day prior to the related Interest Reset Date (a "Commercial Paper Rate Determination Date") of the rate (expressed as a percentage per annum) for commercial paper having the Index Maturity specified above, as such rate shall be published in H.15(519) (as hereinafter defined) under the heading "Commercial Paper - Nonfinancial", or (b) if such rate is not so published prior to 9:00 a.m., New York City time, on the Calculation Date, the Money Market Yield as of such Commercial Paper Rate Determination Date of the rate for commercial paper of the Index Maturity as published in Composite Quotations (as hereinafter defined) under the heading "Commercial Paper", or (c) if none of such rates is published by 3:00 p.m., New York City time, on the Calculation Date, the Money Market Yield of the arithmetic mean of the offered rates, as of 11:00 a.m., New York City time, on such Commercial Paper Rate Determination Date, of three leading dealers in commercial paper in The City of New York selected by the Calculation Agent, in its discretion (after consultation with the Company), for commercial paper of the Index Maturity placed for a nonfinancial issuer whose bond rating is "AA," or the equivalent, from a nationally recognized statistical rating organization; provided, however, that if the dealers selected as aforesaid are not quoting offered rates as described in clause (c) above, the Commercial Paper Rate for such Interest Reset Period shall be deemed to be the same as the Commercial Paper Rate for the preceding Interest Reset Period (or, if there was no such previous Interest Reset Period, the rate of interest hereon for such Interest Reset Period shall be the Initial Interest Rate).

"Money Market Yield" shall be a yield calculated in accordance with the following formula: Money Market Yield = D x 360 x 100 360 - (D x M) where "D" refers to the applicable per annum rate for commercial paper quoted on a bank discount basis and expressed as a decimal, and "M" refers to the actual number of days in the Index Maturity specified above. Determination of Federal Funds Rate If the Base Rate specified above is the Federal Funds Rate, this Security shall bear interest for each Interest Reset Period at a rate calculated with reference to the Federal Funds Rate, determined as set forth below, and the Spread or Spread Multiplier, if any, and subject to the Maximum Interest Rate, if any, and the Minimum Interest Rate, if any, specified above. The "Federal Funds Rate" for each Interest Reset Period shall be determined by the Calculation Agent on the Calculation Date and shall be (a) the rate (expressed as a percentage per annum) as of the second Business Day prior to the related Interest Reset Date (a "Federal Funds Rate Determination Date") for Federal funds as published in H.15(519) under the heading "Federal Funds (Effective)", or (b) if such rate is not so published by 9:00 A.M., New York City time, on the Calculation Date, the rate on such Federal Funds Rate Determination Date as published in Composite Quotations under the heading "Federal Funds/Effective Rate", or (c) if neither of such rates is published by 3:00 P.M., New York City time, on the Calculation Date, the arithmetic mean of the rates for the last transaction in overnight Federal funds as of 11:00 A.M., New York City time, on such Federal Funds Rate Determination Date arranged by three leading brokers in Federal Funds transactions in The City of New York selected by the Calculation Agent, in its discretion (after consultation with the Company); provided, however, that if the brokers selected as aforesaid by the Calculation Agent are not quoting as described in clause (c) above, the Federal Funds Rate for such Interest Reset Period shall be the same as the Federal Funds Rate for the immediately preceding Interest Reset Period (or, if there was no such previous Interest Reset Period, the rate of interest hereon for such Interest Reset Period shall be the Initial Interest Rate). Determination of LIBOR If the Base Rate specified above is LIBOR, this Security shall bear interest for each Interest Reset Period at a rate calculated with reference to LIBOR, determined as set forth below, and the Spread or Spread Multiplier, if any, and subject to the Maximum Interest Rate, if any, and the Minimum Interest Rate, if any, specified above. "LIBOR" for each Interest Reset Period shall be determined by the Calculation Agent and shall be: (a)(i) if "LIBOR Reuters" is specified above as the Reporting Service, the arithmetic mean of the offered rates (unless the specified Designated LIBOR Page (as hereinafter defined) by its terms provides only for a single rate, in which case such single rate shall be used) for deposits in the Index Currency specified above in the London interbank market, for the period of the Index Maturity specified above commencing on the related Interest Reset Date for such Interest Reset Period, which appear or appears on the Designated LIBOR Page at approximately 11:00 a.m., London time, on the second London Banking Day (as hereinafter defined) prior to such Interest Reset Date (a "LIBOR Determination Date"), or (ii) if "LIBOR Telerate" is specified above as the Reporting Service, the rate for deposits in the Index Currency, for the period of the Index Maturity commencing on such Interest Reset Date (or, if the pound sterling is the Index Currency, commencing on the LIBOR Determination Date) that appears on the Designated LIBOR Page at approximately 11:00 a.m., London time, on such LIBOR Determination Date;

(b) with respect to a LIBOR Determination Date on which fewer than two offered rates appear (if "LIBOR Reuters" is specified above as the Reporting Service and calculation of LIBOR is based on the arithmetic mean of the offered rates) or on which no rate appears (if the Reporting Service specified above is either (x) "LIBOR Reuters" and the Designated LIBOR Page by its terms provides only for a single rate or (y) "LIBOR Telerate"), the Calculation Agent shall request the principal London office of each of four major reference banks in the London interbank market selected by the Calculation Agent, in its discretion (after consultation with the Company), to provide the Calculation Agent with its offered quotations for deposits in the Index Currency, for the period of the Index Maturity commencing on the Interest Reset Date (or, if the pound sterling is the Index Currency, commencing on the LIBOR Determination Date) for such Interest Reset Period and in a principal amount equal to an amount of not less than U.S.$1 million (or the equivalent amount in the Index Currency) that is representative of a single transaction in the Index Currency in such market at such time, to prime banks in the London interbank market at approximately 11:00 a.m., London time, on such LIBOR Determination Date; if at least two such quotations are provided, LIBOR, in respect of such LIBOR Determination Date, shall be the arithmetic mean of such quotations; (c) if fewer than two such quotations are so provided, LIBOR in respect of such LIBOR Determination Date shall be the arithmetic mean of the rates quoted by three major banks in the applicable Principal Financial Center for the country of the Index Currency on such LIBOR Determination Date selected by the Calculation Agent, in its discretion (after consultation with the Company), at approximately 11:00 a.m. on such LIBOR Determination Date, for loans in the Index Currency to leading European banks, for the period of the Index Maturity commencing on the Interest Reset Date (or, if the pound sterling is the Index Currency, commencing on the LIBOR Determination Date) for such Interest Reset Period and in a principal amount of not less than U.S.$1 million (or the equivalent amount in the Index Currency) that is representative of a single transaction in the Index Currency in such market at such time; provided, however, that if fewer than three banks selected as aforesaid by the Calculation Agent are quoting rates described in this clause (c), LIBOR for such Interest Reset Period shall be the same as LIBOR for the immediately preceding Interest Reset Period (or, if there was no such previous Interest Reset Period, the rate of interest hereon for such Interest Reset Period shall be the Initial Interest Rate). "Designated LIBOR Page" means (x) if "LIBOR Reuters" is specified above as the Reporting Service, the display on the Reuters monitor money rates service (or any successor service) for the purpose of displaying the London interbank rates of major banks for the applicable Index Currency, or (y) if "LIBOR Telerate" is specified above as the Reporting Service, the display on the Dow Jones Market service (formerly known as the Dow Jones Telerate Service), or any successor service, for the purpose of displaying the London interbank rates of major banks for the Index Currency. If neither LIBOR Reuters nor LIBOR Telerate is specified above as the Reporting Service, LIBOR shall be determined as if LIBOR Telerate Page 3750 had been specified.

The "Prime Rate" for each Interest Reset Period shall be determined by the Calculation Agent on the Calculation Date and shall be (a) the rate (expressed as a percentage per annum) as of the second Business Day prior to the related Interest Reset Date (a "Prime Rate Determination Date") set forth in H.15(519) opposite the caption "Bank Prime Loan", or (b) if such rate is not so published prior to 3:00 p.m., New York City time, on the Calculation Date, the arithmetic mean of the rates publicly announced by each bank named on the Reuters Screen USPRIME1 Page (as defined below) as such bank's prime rate or base lending rate as in effect on such Prime Rate Determination Date as quoted on the Reuters Screen USPRIME1 Page on such Prime Rate Determination Date or (c) if fewer than four such rates appear on the Reuters Screen USPRIME1 Page for such Prime Rate Determination Date, the arithmetic mean of the prime rates quoted on the basis of the actual number of days in the year divided by 360 as of the close of business on such Prime Rate Determination Date by at least two of three major money center banks in The City of New York selected by the Calculation Agent, in its discretion (after consultation with the Company), from which quotations are requested; provided, however, that if fewer than two such prime rates are so quoted by major money center banks as aforesaid, there shall be included in the group of rates whose arithmetic mean is to be so determined the prime rates or base lending rates, as of such Prime Rate Determination Date, of that number of substitute banks or trust companies organized and doing business under the laws of the United States, or any State thereof, in each case having total equity capital of at least U.S. $500 million and being subject to supervision or examination by Federal or State authority, selected by the Calculation Agent, in its discretion (after consultation with the Company), which, when added to the number of rates provided by major money center banks as aforesaid, shall equal two. If in any calendar month the Prime Rate is not published in H.15(519) and the banks or trust companies selected as aforesaid are not quoting as described in the preceding paragraph, the "Prime Rate" for the applicable Interest Reset Period shall be Prime Rate for the immediately preceding Interest Reset Period (or, if there was no such previous Interest Reset Period, the rate of interest hereon for such Interest Reset Period shall be the Initial Interest Rate). "Reuters Screen USPRIME1 Page" means the display designated as Page "USPRIME1" on the Reuters monitor money rates service (or such other page as may replace the USPRIME1 Page on that service for the purpose of displaying prime rates or base lending rates of major United States banks).

The "Treasury Rate" for each Interest Reset Period shall be determined by the Calculation Agent on the Calculation Date and shall be (a) the rate (expressed as a percentage per annum) for the auction held on the Treasury Rate Determination Date (as hereinafter defined) for such Interest Reset Period of

direct obligations of the United States ("Treasury bills") having the Index Maturity specified above, as such rate shall be published in H.15(519) under the heading "U.S. Government Securities - Treasury bills - auction average (investment)", or (b) if such rate is not published prior to 9:00 a.m., New York City time, on the Calculation Date, the auction average rate (expressed as a bond equivalent on the basis of a year of 365 or 366 days, as applicable, and applied on a daily basis) on such Treasury Rate Determination Date as otherwise announced by the United States Department of Treasury, or (c) if the results of the auction of Treasury bills having such Index Maturity are not published or reported as provided above by 3:00 p.m., New York City time, on the Calculation Date, or if no such auction is held on such Treasury Rate Determination Date, a yield to maturity (expressed as a bond equivalent on the basis of a year of 365 or 366 days, as applicable, and applied on a daily basis) of the arithmetic mean of the secondary market bid rates, as of approximately 3:30 p.m., New York City time, on such Treasury Rate Determination Date, of three leading primary United States government securities dealers selected by the Calculation Agent, in its discretion (after consultations with the Company), for the issue of Treasury bills with a remaining maturity closest to such Index Maturity; provided, however, that if the dealers selected as aforesaid by the Calculation Agent are not quoting bid rates as described in clause (c) above, then the "Treasury Rate" for such Interest Reset Period shall be deemed to be the same as the Treasury Rate for the immediately preceding Interest Reset Period (or, if there was no such previous Interest Reset Period, the rate of interest hereon for such Interest Reset Period shall be the Initial Interest Rate). The "Treasury Rate Determination Date" for each Interest Reset Period shall be the day of the week in which the Interest Reset Date for such Interest Reset Period falls on which Treasury bills would normally be auctioned. (As of the Original Interest Accrual Date, Treasury bills are normally sold at auction on Monday of each week, unless that day is a legal holiday, in which case the auction is normally held on the following Tuesday, except that such auction may be held on the preceding Friday.) If, as the result of a legal holiday, an auction is so held on the preceding Friday, such Friday shall be the Treasury Rate Determination Date pertaining to the Interest Reset Period commencing in the next succeeding week. If an auction date shall fall on any day that would otherwise be an Interest Reset Date for a Treasury Rate Note, then such Interest Reset Date shall instead be the Business Day immediately following such auction date. If, as specified above, this Security is redeemable, this Security is subject to redemption at any time on or after the Initial Redemption Date specified above, as a whole or in part, at the election of the Company, at the applicable redemption price (as described below) plus accrued interest to the date fixed for redemption. Such redemption price shall be the Initial Redemption Price specified above for the twelve-month period commencing on the Initial Redemption Date and shall decline for the twelve-month period commencing on each anniversary of the Initial Redemption Date by a percentage of principal amount equal to the Reduction Percentage specified above until such redemption price is 100% of the principal amount of this Security to be redeemed. Notwithstanding the foregoing, the Company may not, prior to the Redemption Limitation Date, if any, specified above, redeem this Security as contemplated above as a part of, or in anticipation of, any refunding operation by the application, directly or indirectly, of moneys borrowed having an effective interest cost to the Company (calculated in accordance with generally accepted financial practice) less than the effective interest cost to the Company (similarly calculated) of this Security. [Insert provisions, if any, for redemption pursuant to a sinking fund or analogous provision or at the option of the Holder.]

Notice of redemption [(other than at the election of the Holder)] shall be given by mail to Holders of Securities, not less than 30 days nor more than 60 days prior to the date fixed for redemption, all as provided in the Indenture. As provided in the Indenture, notice of redemption at the election of the Company as aforesaid may state that such redemption shall be conditional upon the receipt by the Trustee of money sufficient to pay the principal of and premium, if any, and interest, if any, on this Security on or prior to the date fixed for such redemption; a notice of redemption so conditioned shall be of no force or effect if such money is not so received and, in such event, the Company shall not be required to redeem this Security. In the event of redemption of this Security in part only, a new Security or Securities of this series, of like tenor, for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. If an Event of Default shall occur and be continuing, the principal of this Security may be declared due and payable in the manner and with the effect provided in the Indenture. The Indenture permits, with certain exceptions as therein provided, the Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the Indenture with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities of all series then Outstanding under the Indenture, considered as one class; provided, however, that if there shall be Securities of more than one series Outstanding under the Indenture and if a proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Securities of any series shall have been issued in more than one Tranche and if the proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all Tranches so directly affected, considered as one class, shall be required; and provided, further, that the Indenture permits the Trustee to enter into one or more supplemental indentures for limited purposes without the consent of any Holders of Securities. The Indenture also contains provisions permitting the Holders of a majority in principal amount of the Securities then Outstanding, on behalf of the Holders of all Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. As provided in the Indenture and subject to certain limitations therein set forth, this Security or any portion of the principal amount hereof will be deemed to have been paid for all purposes of the Indenture and to be no longer Outstanding thereunder, and, at the election of the Company, the Company's entire indebtedness in respect thereof will be satisfied and discharged, if there has been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust, money in an amount which will be sufficient and/or Eligible Obligations, the principal of and interest on which when due, without regard to any reinvestment thereof, will provide moneys which, together with moneys so deposited, will be sufficient to pay when due the principal of and interest on this Security when due.

The Securities of this series are issuable only as registered Securities, without coupons, and in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of the same series and Tranche, of any authorized denominations, as requested by the Holder surrendering the same, and of like tenor upon surrender of the Security or Securities to be exchanged at the corporate trust office of The Chase Manhattan Bank in New York, New York or such other office or agency as may be designated by the Company from time to time. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. Prior to due surrender of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the absolute owner hereof for all purposes (subject to Section 307 of the Indenture), whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

          Avista Corporation
          1411 East Mission Avenue
          Spokane, Washington 99202


          Dear Ladies and Gentlemen:

               We are acting as counsel to Avista Corporation (the
          "Company") in connection with the proposed issuance by the
          Company of unsecured debt securities (the "Debt Securities")
          under the Indenture, dated as of April 1, 1998 (the "Indenture"),
          from the Company to The Chase Manhattan Bank, as trustee, to be
          issued and sold from time to time by the Company in one or more
          public offerings.  The Debt Securities are to be issued in an
          aggregate principal amount of up to $400,000,000, as contemplated
          in the registration statement on Form S-3 proposed to be filed by
          the Company with the Securities and Exchange Commission on or
          about the date hereof for the registration of the Debt Securities
          under the Securities Act of 1933, as amended (the "Act"), said
          registration statement, as it may be amended, and including the
          exhibits thereto, being hereinafter called the "Registration
          Statement."

               We have examined and are familiar with originals or copies,
          certified or otherwise identified to our satisfaction, of (i) the
          Registration Statement, (ii) the Indenture, (iii) the resolutions
          of the Company's Board of Directors authorizing the issuance and
          sale of the Debt Securities, and (iv) a Certificate of
          Existence/Authorization issued by the Secretary of State of the
          State of Washington.  We have also examined such other documents
          and satisfied ourselves as to such other matters as we have
          deemed necessary in order to render this opinion.  As to various
          facts material to the opinions expressed below, we have relied on


          < PAGE >


          Avista Corporation

          July 2, 1999
          Page -2


          certificates of public officials, certificates of officers or
          employees of the Company, representations contained in documents,
          and other oral or written assurances by officers or employees of
          the Company.

               Based upon the foregoing and subject to the qualifications
          herein expressed, we are of the opinion that:

                    (a) the Company is a corporation duly incorporated and
               validly existing under the laws of the State of Washington;
               and

                    (b)  the issuance and sale by the Company of the Debt
               Securities as contemplated in the Registration Statement
               have been duly authorized by the Company's Board of
               Directors, subject to the terms and limitations set forth in
               the resolutions of the Board of Directors; and no further
               corporate action on the part of the Company is necessary to
               authorize such issuance and sale of the Debt Securities or
               in order for the Debt Securities, when so issued and sold,
               to constitute valid and binding obligations of the Company,
               provided that such issuance and sale is within the terms and
               limitations set forth in such resolutions.


               We are also of the opinion that when:

                    (i) the Registration Statement shall have become
               effective under the Act (and assuming that no stop order
               shall have been issued), and

                    (ii) the Washington Utilities and Transportation
               Commission, the California Public Utilities Commission, the
               Idaho Public Utilities Commission and the Public Utility
               Commission of Oregon shall have issued, pursuant to
               applications filed by the Company with said regulatory
               authorities, appropriate orders authorizing the issuance and
               sale by the Company of the Debt Securities,

          then no further approval, authorization, consent or other order
          of, or filing with, any governmental agency of the States of
          Washington, California, Idaho, Montana, and Oregon will be
          legally required for the authorization of the issuance and sale
          by the Company of the Debt Securities or in order for the Debt
          Securities, when issued and sold as anticipated in the aforesaid
          orders, to be legally issued and to constitute binding
          obligations of the Company.

          Ladies and Gentlemen:

               We are acting as counsel to Avista Corporation (the
          "Company") in connection with the proposed issuance by the
          Company of unsecured debt securities (the "Debt Securities")
          under the Indenture, dated as of April 1, 1998 (the "Indenture"),
          from the Company to The Chase Manhattan Bank, as trustee, to be
          issued and sold from time to time by the Company in one or more
          public offerings.  The Debt Securities are to be issued in an
          aggregate principal amount of up to $400,000,000, as contemplated
          by the registration statement on Form S-3 proposed to be filed by
          the Company with the Securities and Exchange Commission on or
          about the date hereof for the registration of the Debt Securities
          under the Securities Act of 1933, as amended (the "Act"), said
          registration statement, as it may be amended, and including the
          exhibits thereto, being hereinafter called the "Registration
          Statement."

               We have examined and are familiar with originals or copies,
          certified or otherwise identified to our satisfaction, of (i) the
          Registration Statement and (ii) the Indenture. We have also
          examined such other documents and satisfied ourselves as to such
          other matters as we have deemed necessary in order to render this
          opinion.

               Based upon the foregoing and subject to the qualifications
          hereinafter expressed, we are of the opinion that when:

                    (a)  the Registration Statement shall have become
               effective under the Act; and

                    (b)  the Washington Utilities and Transportation
               Commission, the California Public Utilities Commission, the
               Idaho Public Utilities Commission and the Public Utility
               Commission of Oregon shall have issued, pursuant to
               applications filed by the Company with said regulatory
               authorities, appropriate orders authorizing the issuance and
               sale by the Company of the Debt Securities (such matters
               having been addressed in the opinion of Paine, Hamblen,
               Coffin, Brooke & Miller LLP, which is being filed as Exhibit
               5(a) to the Registration Statement); and

                    (c) the Debt Securities have been issued, sold and paid
               for as contemplated in the aforesaid orders and in the
               Registration Statement,

          then the Debt Securities will be legally issued and will be
          binding obligations of the Company.

               The opinions expressed herein are limited to the laws of the
          State of New York and the federal law of the United States
          (excluding therefrom principles of conflicts of laws, state
          securities or blue sky laws).  To the extent that such opinions
          relate to or are dependent upon matters governed by the laws of
          other States, we have assumed the legal conclusions set forth in
          the opinion of Paine, Hamblen, Coffin, Brooke & Miller LLP, which
          is being filed as Exhibit 5(a) to the Registration Statement.

               We hereby consent to the filing of this opinion as Exhibit
          5(b) to the Registration Statement and to the references to our
          firm, as counsel, in the Registration Statement and in the
          prospectus contained therein.  In giving the foregoing consent,
          we do not admit that we are within the category of persons whose
          consent is required under Section 7 of the Act or the rules and
          regulations promulgated thereunder.
