                                     SUMMARY

     This summary, which is presented solely to furnish limited introductory
information regarding Avista Corporation (Avista Corp. or the Company), the
exchange offer and the new notes, has been selected from the detailed
information contained elsewhere in this prospectus (including the documents
incorporated by reference). This summary does not contain all of the information
that you should consider before making any investment decision. The terms "we",
"us" and "our" refer to Avista Corp. and, when applicable, its subsidiaries. You
should read the entire prospectus carefully.

                               AVISTA CORPORATION

     Avista Corp., which was incorporated in the State of Washington in 1889, is
an electric and gas utility company having operations located in the Pacific
Northwest. We also have subsidiaries involved in energy, information and
technology businesses. As of March 31, 2001, our employees included
approximately 1,460 people in our utility operations and approximately 800
people in our subsidiary businesses. Our corporate headquarters are in Spokane,
Washington, which serves as the Inland Northwest's center for manufacturing,
transportation, health care, education, communication, agricultural and service
businesses.

     Our operations are organized into four lines of business--Avista Utilities,
Energy Trading and Marketing, Information and Technology, and Avista Ventures.
Avista Utilities, which is an operating division of Avista Corp. and not a
separate entity, represents the regulated utility operations. Avista Capital, a
wholly-owned subsidiary of Avista Corp., owns all of the subsidiary companies
engaged in the other lines of business.

                               THE EXCHANGE OFFER

GENERAL                       Avista Corp. is offering to exchange $1,000 in
                              principal amount of new notes for each $1,000 in
                              principal amount of old notes that noteholders
                              properly tender and do not withdraw before the
                              expiration date. Avista Corp. will issue the new
                              notes on or promptly after the expiration date.
                              There is $400,000,000 in aggregate principal
                              amount of old notes outstanding. See THE EXCHANGE
                              OFFER.

EXPIRATION DATE               The exchange offer will expire at 5:00 p.m., New
                              York City time, on , 2001 unless extended. If
                              extended, the term "expiration date" will mean the
                              latest date and time to which the exchange offer
                              is extended. Avista Corp. will accept for exchange
                              any and all old notes which are properly tendered
                              in the exchange offer and not withdrawn before
                              5:00 p.m., New York City time, on the expiration
                              date.

RESALE OF NEW NOTES           Based on interpretive letters written by the staff
                              of the Securities and Exchange Commission to
                              companies other than Avista Corp., Avista Corp.
                              believes that, subject to certain exceptions, the
                              new notes may generally be offered for resale,
                              resold and otherwise transferred by any holder
                              thereof, without compliance with the registration
                              and prospectus delivery provisions of the
                              Securities Act of 1933. However, any holder who is
                              an "affiliate" of Avista Corp. within the meaning
                              of Rule 405 under the Securities Act would have to
                              comply with these provisions unless an exemption
                              was available.

                              If Avista Corp.'s belief is inaccurate, holders of
                              new notes who offer, resell or otherwise transfer
                              new notes in violation of the Securities Act may
                              incur liability under that Act. Avista Corp. will
                              not assume or indemnify holders against this
                              liability.

                                   of any existing law, statute, rule or

                              of first mortgage bonds, which is secured by a
                              lien on substantially all of Avista Corp.'s
                              utility plant assets. Avista Corp. also has a
                              credit agreement which is secured by a pledge of
                              the capital stock of Avista Capital. By reason,
                              and to the extent, of this mortgage and this
                              pledge, the first mortgage bonds and the
                              borrowings under this credit agreement will rank
                              prior to the new notes.

OPTIONAL REDEMPTION           Each of the new notes will be redeemable in whole
                              or in part at our option at any time, at a
                              redemption price equal to the greater of (i) 100%
                              of the principal amount of the new notes being
                              redeemed or (ii) the sum of the present values of
                              the remaining scheduled payments of the principal
                              of and interest on the new notes being redeemed
                              discounted to the date of redemption on a
                              semi-annual basis (assuming a 360-day year
                              consisting of twelve 30-day months) at the
                              Treasury Yield (as defined herein) plus 50 basis
                              points; plus, in either case, whichever is
                              applicable, accrued interest on the new notes

(1) In December 1998, we converted shares of common stock for Convertible Preferred Stock, which was responsible for a number of changes in the data in 2000, 1999 and 1998 from 1997. (2) "Earnings Before Interest, Taxes, Depreciation and Amortization", or EBITDA, represents net income before interest expense (including related amortization), taxes based on income, depreciation and amortization, to interest expense (including related amortization). EBITDA is commonly used to analyze companies on the basis of operating performance, leverage and liquidity. While EBITDA should not be construed as a substitute for operating income or a better measure of liquidity than cash flow from operating activities, which are determined in accordance with generally accepted accounting principles, we have presented EBITDA to provide additional information with respect to our ability to meet future debt service, capital expenditure and working capital requirements. EBITDA is not a measure determined under generally accepted accounting principles. 7 Also, as calculated above, EBITDA may not be comparable to similarly titled measures reported by other companies. "Fixed Charges" include interest (whether or not capitalized) and related amortization. (3) "Earnings," as defined by Regulation S-K, represent the aggregate of (1) net income before the cumulative effect of an accounting change, (2) taxes based on income, (3) investment tax credit adjustments--net and (4) fixed charges. "Fixed Charges" include interest (whether expensed or capitalized), related amortization and estimated interest applicable to rentals. 8 RISK FACTORS You should carefully consider the following factors in addition to the other information in this prospectus. WE WILL NEED TO FINANCE OUR OPERATIONS AND CAPITAL EXPENDITURES. OUR LEVEL OF INDEBTEDNESS COULD AFFECT OUR ABILITY TO DEDICATE SUFFICIENT CASH FLOW TO THESE PURPOSES, WHICH WOULD ULTIMATELY AFFECT OUR ABILITY TO MEET OUR OBLIGATIONS ON THE NEW NOTES. We have incurred significant long-term indebtedness to support capital expenditures and to maintain working capital. At April 30, 2001, after giving effect to the issuance of the old notes, we had, total long-term debt of approximately $1,079.5 million. In addition, we will need to finance capital expenditures and obtain additional working capital from time to time. The cash requirements to service the total amount of our indebtedness, both short-term and long-term, could reduce the amount of cash flow available to fund working capital, future acquisitions, the deferral accounts discussed below, other corporate requirements and capital expenditures. IF WE ARE UNABLE TO RECOVER DEFERRED PURCHASED POWER AND, TO A LESSER EXTENT, NATURAL GAS COSTS EXCEEDING AMOUNTS INCLUDED IN CURRENT RETAIL RATES, WE MAY EXPERIENCE AN ADVERSE IMPACT ON CASH FLOW AND EARNINGS. Purchased power and natural gas costs incurred to serve our retail customers are generally recovered or expected to be recovered in base rates. However, there is a lag between the time we incur any increases in these costs and the time we collect these increases from customers. As more fully described in Note 1 of Notes to Financial Statements--"Power Cost Deferrals and Power and Natural Gas Adjustment Provisions" in Avista Corp.'s Annual Report on Form 10-K for the year 2000, costs in excess of those included in base rates are deferred as an asset on our balance sheet and not shown as an expense until recovered from our retail customers. In 2000 the price of electric energy in western wholesale markets rose to unprecedented levels, accompanied by increases in natural gas prices, in both cases far above the levels included in base rates. These market conditions are expected to continue in 2001. We have mechanisms in place to recover (subject to certain limitations) increases in gas costs in Washington, Idaho and Oregon, and we regularly make filings to recover increased costs under these mechanisms. As of March 31, 2001, we had balances of deferred gas costs totaling $79.3 million. We also have a mechanism in place to recover (subject to certain limitations) increases in purchased power costs in Idaho and had a balance of deferred purchased power costs in Idaho of $5.2 million, a power cost rebate of $0.9 million which is being flowed through to customers, and a surcharge deferral balance of $6.8 million, as of March 31, 2001. On March 23, 2001, we filed an application in Washington to establish the prudency of the purchased power costs incurred as well as for approval of a method to recover the cost increases. As of March 31, 2001, we had a balance of deferred purchased power costs of $56 million plus accrued interest of $0.7 million in Washington. We will be able to recover these balances of deferred costs only in the amounts, and at the times, authorized by the respective state commissions. As discussed in "Recent Developments", on May 23, 2001, the Washington public utility commission approved a settlement agreement reached among Avista Corp., the staff of that commission and other parties. RECENT CHANGES IN THE ENERGY MARKETS IN THE WESTERN UNITED STATES HAVE LED TO SIGNIFICANT INCREASES IN WHOLESALE POWER PRICES. BECAUSE OF THESE HIGH PRICE LEVELS, A DECREASE IN OUR POWER RESOURCE AVAILABILITY OR AN INCREASE IN CUSTOMER DEMAND THAT REQUIRES US TO PURCHASE MORE POWER COULD HAVE AN ADVERSE IMPACT ON OUR CASH FLOW AND EARNINGS. Wholesale power prices rose dramatically starting in the second quarter of 2000 and remain significantly above historic levels in the Pacific Northwest, including our service territory, and throughout the western United States. Significant emerging factors include the gradual depletion of excess generating capacity in the West, increasing instances of transmission congestion and increased ownership of generating facilities by entities which are not traditional "public utilities." Also, wholesale power markets have been affected by the restructuring of electric utility regulation at both state and federal levels. 9 Federal and state officials, including the Federal Energy Regulatory Commission, the California Public Utility Commission and the Attorneys General of California, Oregon and Washington, have commenced reviews to determine the causes of the changes in the wholesale energy markets. Under normal water conditions and customer demand, we would be able to provide almost all of our forecasted native load energy requirements with our own generation plants and long-term contracts until the end of 2003, with the balance covered through short-term contracts. However, current forecasts show streamflow conditions for hydroelectric generation for 2001 at no better than 60% of normal. In response to the reduced hydroelectric generation, we have made additional fixed price purchases of energy to cover our retail and firm wholesale load requirements for 2001 with additional purchases from the higher cost short-term wholesale market. If hydroelectric conditions further deteriorate, or our generating plants do not operate as planned, or weather conditions cause retail loads to increase, we would incur additional costs from increased purchases in the higher cost short-term wholesale energy market. This would have an adverse impact on our cash flow and, if not ultimately recovered, on our earnings. WE ARE SUBJECT TO THE RISKS INHERENT IN THE UTILITY BUSINESS, INCLUDING NORMAL OPERATING RISKS, SUCH AS THE COST OF FUEL AND THE POSSIBILITY OF PLANT OUTAGES, AND, IN OUR CASE, THE SUFFICIENCY OF STREAMFLOWS. WE ARE ALSO SUBJECT TO REGULATORY RISKS, SUCH AS INCREASED ENVIRONMENTAL REGULATION AND THE CHALLENGE TO OBTAIN SATISFACTORY RATE RELIEF, AS WELL AS TO RISKS ASSOCIATED WITH DEREGULATION OF ENERGY MARKETS. The utility business involves many operating risks. For example, there may be a breakdown or failure of electrical generating or other equipment, fuel interruption or performance below expected levels of output or efficiency. Also, some of our facilities use natural gas and coal in their generation of electricity. The market prices and availability of natural gas and coal fluctuate. Increasing prices for these commodities or a lack of availability could impair our cash flow and, if not ultimately recovered, on our earnings. In addition, our hydroelectric plants require continuous water flow for their operation. A drought or other water flow impairment may limit our ability to produce and market electricity from these facilities. In addition, the utility business is subject to complex and stringent energy, environmental, and other governmental laws and regulations. The acquisition, ownership and operation of power generation facilities requires numerous permits, approvals, and certificates from appropriate federal, state, and local governmental agencies. If environmental regulations, such as emission limits, are tightened, this could increase the amount we must invest to bring our facilities into compliance. In general, the prices we are allowed to charge for our electric and natural gas services are intended to provide, after recovery of allowable operating expenses, an opportunity to earn a reasonable rate of return. The regulatory commissions of the states in which we operate may limit our ability to increase prices, and future changes in the regulatory framework may also affect our ability to earn a reasonable rate of return. More recently, wholesale power markets have been affected by the restructuring of electric utility regulation at both federal and state levels. In particular, deregulation in California, combined with increased demand and limitations on supply, has affected wholesale power prices throughout the West. In addition, although there is currently no legislative or regulatory movement toward deregulation in Washington or Idaho, in a deregulated environment, evolving technologies might provide alternate energy supplies at lower costs, leading to lower adjusted market prices and reducing margins for traditional utilities that use technologies and generating assets with capital and operating costs higher than the lower adjusted market price. WE ARE SUBJECT TO THE FINANCIAL, LIQUIDITY, CREDIT AND COMMODITY PRICE RISKS ASSOCIATED WITH ENERGY TRADING AND MARKETING ACTIVITIES. Our subsidiary, Avista Energy, trades electricity and natural gas, along with derivative commodity instruments, including futures, options, swaps and other contractual arrangements. Most transactions are conducted on a largely unregulated "over-the-counter" basis, there being no central clearing mechanism (except in the case of specific instruments traded on the commodity exchanges). As a result of these trading activities, we are subject to various risks, including market risk, liquidity risk, commodity risk and credit risk. Although Avista Energy scaled back operations to focus primarily in the western United States during 2000, its trading operations continue to be affected by, among other things, volatility of prices within the electric energy and natural gas 10 markets, the demand for and availability of energy, lower unit margins on new sales contracts and deregulation of the electric utility industry. Avista Energy is renegotiating its credit agreement with its primary lending banks which expired on May 31, 2001. Avista Energy anticipates receiving an extension to June 30, 2001 of its existing credit agreement and anticipates the completion of documentation and closing of a new credit agreement by the end of June 2001. The existing agreement contains a variety of covenants and restrictions, including restrictions on dividends. In connection with matching loads and resources, Avista Utilities also engages in wholesale sales and purchases of electric capacity and energy, and, accordingly, is also subject to commodity price risk, credit risk and other risks associated with these activities. AVISTA CORPORATION GENERAL Avista Corp., which was incorporated in the State of Washington in 1889, is an electric and gas utility company having operations located in the Pacific Northwest. We also have subsidiaries involved in energy, information and technology businesses. As of March 31, 2001, our employees included approximately 1,460 people in our utility operations and approximately 800 people in our subsidiary businesses. Our corporate headquarters are in Spokane, Washington, which serves as the Inland Northwest's center for manufacturing, transportation, health care, education, communication, agricultural and service businesses. Our operations are organized into four lines of business--Avista Utilities, Energy Trading and Marketing, Information and Technology, and Avista Ventures. Avista Utilities, which is an operating division of Avista Corp. and not a separate entity, represents the regulated utility operations. Avista Capital, a wholly owned subsidiary of Avista Corp., owns all of the subsidiary companies engaged in the other lines of business. Avista Corp.'s lines of business, and the companies included within them, are illustrated below: ------------------ AVISTA CORPORATION* ------------------ / ----------------------------------------------- / / - ---------------- -------------- AVISTA UTILITIES** AVISTA CAPITAL* - ---------------- -------------- / ----------------------------------------------------------------- / / / ----------------------- --------------- ----------------- ENERGY INFORMATION AND AVISTA VENTURES** TRADING AND MARKETING** TECHNOLOGY** ----------------- ----------------------- --------------- / / / / ------------- / ---------------- / --------------- / AVISTA ENERGY* / AVISTA ADVANTAGE*/ AVISTA VENTURES* / ------------- / ---------------- / --------------- / ------------ / ----------- / ----- / AVISTA POWER*/ AVISTA LABS* / OTHER*/ ------------/ ----------- / ----- ------------ / --------------------- / AVISTA-STEAG*/ AVISTA COMMUNICATIONS*/ ------------ --------------------- * - denotes a business entity. ** - denotes an operating division or line of business 11 ENERGY BUSINESSES Avista Utilities provides electricity and natural gas distribution and transmission services in a 26,000 square mile area in eastern Washington and northern Idaho with a population of approximately 835,000. It also provides natural gas distribution service in a 4,000 square mile area in northeast and southwest Oregon and in the South Lake Tahoe region of California, with the population in these areas approximating 500,000. At the end of 2000, retail electric service was supplied to approximately 313,000 customers in eastern Washington and northern Idaho; retail natural gas service was supplied to approximately 279,000 customers in parts of Washington, Idaho, Oregon and California. Our retail customers include residential, commercial and industrial classifications, with the residential classification accounting for the most energy consumed and the greatest contribution to revenues. Avista Utilities also engages in wholesale sales and purchases of electric capacity and energy. In addition to providing electric transmission and distribution services, Avista Utilities is responsible for electric generation and production. Avista Utilities owns and operates eight hydroelectric projects, a wood-waste fueled generating station and two natural gas-fired combustion turbine (CT) generating units. It also owns a 15% share in a two-unit coal-fired generating facility and leases and operates two additional natural gas-fired CT generating units. These facilities have a total net capability of approximately 1,470 megawatts, of which 65% is hydroelectric and 35% is thermal. In addition, Avista Utilities has a number of long-term power purchase and exchange contracts that increase its available resources. Under normal water conditions and loads, Avista Utilities' own generation plants and long-term contracts would be able to provide approximately 90% of its forecasted native load energy requirements in 2001, and 100% thereof in 2002 and 2003. The balance would be covered through short-term contracts. Avista Utilities has covered essentially all of its electric energy requirements in the forward markets for 2001. For a discussion of current water conditions, see RISK FACTORS. Avista Utilities anticipates residential and commercial electric load growth to average approximately 2.6% annually for the next five years primarily due to expected increases in both population and the number of businesses in its service territory. The number of electric customers is expected to increase and the average annual usage by residential customers is expected to remain steady. Avista Utilities expects natural gas load growth, including transportation volumes, in its Washington and Idaho service area to average approximately 2.7% annually for the next five years. The Oregon and South Lake Tahoe, California service areas are anticipated to realize 3.4% growth annually during that same period. The natural gas load growth is primarily due to expected conversions from electric space and water heating to natural gas, and increases in both population and the number of businesses in its service territories. These electric and natural gas load growth projections are based on purchased economic forecasts, publicly available studies, and internal analysis of company-specific data, such as energy consumption patterns and internal business plans. See "Management's Discussion and Analysis of Financial Condition and Results of Operations--Future Outlook" in Avista Corp.'s Annual Report on Form 10-K for the year ended December 31, 2000 and its Current Report on Form 10-Q for the quarter ended March 31, 2001 for additional information. Energy Trading and Marketing is comprised of Avista Energy, Inc., Avista Power, Inc. and Avista STEAG, LLC. Avista Energy is an electricity and natural gas trading and marketing business. Avista Power was formed to develop, purchase and own electric generation assets. Avista STEAG is a joint venture between Avista Capital and STEAG AG, a German independent power producer, to develop electric generating assets. On April 27, 2001, Avista Capital gave notice to STEAG AG, electing to terminate the Avista STEAG venture pursuant to its terms. Avista Capital and STEAG AG are now preparing for an orderly winding up and termination of Avista STEAG. Avista Energy, Avista Power and Avista STEAG all operate primarily in the Western Systems Coordinating Council ("WSCC"), which is comprised of the eleven Western states. Avista Energy is in the business of buying and selling electricity and natural gas. Avista Energy's customers include commercial and industrial end-users, electric utilities, natural gas distribution companies and other trading companies. Avista Energy also trades electricity and natural gas derivative commodity instruments. Avista Power has electric generation projects under development and construction in strategic locations primarily in the WSCC. Avista Power and Cogentrix Energy, Inc. have entered into an agreement to jointly build and/or buy interests in natural gas-fired electric generation plants in the states of Washington, Oregon and Idaho. A project under this agreement is the 270 megawatt 12 facility located in Rathdrum, Idaho, with 100% of its output contracted to Avista Energy for 25 years. Non-recourse project financing was completed in March 2000 and the facility is currently under construction, with commercial operation expected to start in late 2001. In December 2000, Avista Utilities selected the Coyote Springs 2 project, a 280-megawatt combined-cycle natural gas-fired plant near Boardman, Oregon to add generation to its portfolio. Construction commenced in January 2001 under a fixed price turnkey engineering, procurement and construction contract with project completion anticipated in mid-2002. The process is underway to transfer ownership from Avista Power to Avista Utilities. Avista Corp. is currently negotiating bank financing for the construction of this project. A portion of the proceeds of the notes may be used to finance construction costs. OTHER BUSINESSES Information and Technology is comprised of Avista Advantage, Inc., Avista Laboratories, Inc. and Avista Communications, Inc. o Avista Advantage is an e-commerce provider of facilities management billing and information services to commercial customers throughout the U.S. and Canada. Its primary product lines include consolidated billing, resource accounting, energy analysis, load profiling and maintenance and repair billing services. o Avista Labs is in the process of developing both modular Proton Exchange Membrane fuel cells for power generation at the site of the consumer or industrial user and fuel cell components. o Avista Communications is an Integrated Communications Provider providing local dial tone, data transport, internet services, voice messaging and other telecommunications services to under-served communities primarily in ten Northwest markets. Avista Communications is also involved in designing, building and managing metropolitan area fiber optic networks. Avista Ventures includes Avista Ventures, Inc. and several other minor subsidiaries. Avista Ventures was formed to align Avista Corp.'s investment and acquisition activities in the strategic growth areas of energy, information and technology. In addition, Avista Ventures hold investments in real estate and majority ownership of AM&D, a metals fabrication and manufacturing business. BUSINESS STRATEGY Avista Corp.'s general business strategy is to: o maintain a strong, low-cost utility business focused on delivering efficient, reliable and high quality service to its customers; o reduce the size and risk associated with its energy trading activities; o pursue opportunities to develop new generation to support the growing power requirements in the Northwest; and o have access to electric and natural gas resources, both owned and under long-term contract, in excess of projected requirements. RECENT DEVELOPMENTS On May 23, 2001, the Washington Utilities and Transportation Commission (the "WUTC") approved a settlement agreement which had been reached among Avista Corp., the staff of the WUTC and other parties with respect to deferred energy costs. The agreement, among other things, provides for the extension of Avista Corp.'s deferral accounting mechanism through February 2003. Due to the planned addition of generating resources as well as the expiration of certain long-term power sale agreements, Avista Utilities expects to be in a power surplus 13 position by July 2002. Avista Utilities further expects the profits from surplus power sales to offset the power cost deferral balance, reducing the balance to zero by the end of February 2003 without any price increase to retail customers. These expectations are based on assumptions as to a number of variables including, but not limited to, streamflow conditions, thermal plan performance, level of retail loads, wholesale market prices and the amount of additional generating resources. Avista Utilities has reserved the right to request an immediate rate surcharge to recover the deferral balance if circumstances change. See RISK FACTORS. On May 31, 2001 the Company renewed its committed line of credit and repaid all outstanding borrowings under that facility. The new $220 million credit facility expires on May 29, 2002. As of May 31, 2001, there were no amounts borrowed under this committed line of credit. The Company is in the process of obtaining a construction loan to finance $120 million of the construction costs for the Coyote Springs 2 project with a term that matches the construction period. A term sheet has been signed with two co-lenders to fully underwrite such construction loan. The Company currently anticipates the completion of the documentation and closing by the end of June 2001. CAPITALIZATION The following table sets forth our consolidated capitalization as of March 31, 2001, as well as our consolidated cash balance and short-term debt (including the current portion of long-term debt). The following data are qualified in their entirety by our financial statements and other information incorporated by reference into this prospectus. The "As Adjusted" column reflects our receipt of proceeds of $388.3 million from the issuance and sale of the Old Notes (after discounts and commissions and estimated offering and exchange offering expenses) and the application of $278.4 million of the net proceeds to the payment of short-term debt (including the current portion of long-term debt).

The Old Notes were sold by Goldman, Sachs & Co. (the "Initial Purchaser") on April 3, 2001 to a limited number of institutional investors (the "Purchasers"). In connection with the sale of the Old Notes, Avista Corp. and the Initial Purchaser entered into an Exchange and Registration Rights Agreement, dated April 3, 2001 (the "Registration Rights Agreement"), which requires, among other things, Avista Corp. (a) to file with the Securities and Exchange Commission (the "SEC") a registration statement under the Securities Act of 1933, as amended (the "Securities Act") with respect to New Notes identical in all material respects to the Old Notes, to use commercially reasonable efforts to cause such registration statement to be declared effective under the Securities Act and to make an exchange offer for the Old Notes as discussed below, or (b) to register the Old Notes under the Securities Act. Avista Corp. is obligated, upon the effectiveness of the exchange offer registration statement referred to in (a) above, to offer the holders of the Old Notes the opportunity to exchange their Old Notes for a like principal amount of New Notes which will be issued without a restrictive legend and may be reoffered and resold by the holder without restrictions or limitations under the Securities Act. A copy of the Registration Rights Agreement has been filed as an exhibit to the Registration Statement of which this prospectus is a part. The Exchange Offer is being made pursuant to the Registration Rights Agreement to satisfy Avista Corp.'s obligations under that agreement. The term "Holder" with respect to the Exchange Offer means any person in whose name Old Notes are registered on Avista Corp.'s books, any other person who has obtained a properly completed assignment from the registered holder or any DTC participant whose Old Notes are held of record by DTC. At the date of this prospectus, the sole Holder of Old Notes is DTC. In participating in the Exchange Offer, a Holder is deemed to represent to Avista Corp., among other things, that (a) the New Notes acquired pursuant to the Exchange Offer are being obtained in the ordinary course of business of the person receiving such New Notes, whether or not such person is the Holder, (b) neither the Holder nor any such other person receiving such new notes is engaging in or intends to engage in a distribution of such New Notes, (c) neither the Holder nor any such other person receiving such new notes has an arrangement or understanding with any person to participate in the distribution of such New Notes, and (d) neither the Holder nor any such other person receiving such new notes is an "affiliate," as defined in Rule 405 under the Securities Act, of Avista Corp. Based on an interpretation by the staff of the SEC set forth in no-action letters issued to third-parties, Avista Corp. believes that the New Notes issued pursuant to the Exchange Offer may be offered for resale and resold or otherwise transferred by any Holder of such New Notes (other than any such Holder which is an "affiliate" of Avista Corp. within the meaning of Rule 405 under the Securities Act and except as otherwise discussed below with respect to Holders which are broker-dealers) without compliance with the registration and prospectus delivery requirements of the Securities Act, so long as such New Notes are acquired in the ordinary course of such Holder's business and such Holder has no arrangement or understanding with any person to participate in the distribution (within the meaning of the Securities Act) of such New Notes. Any Holder who tenders in the Exchange Offer for the purpose of participating in a 15 distribution of the New Notes cannot rely on such interpretation by the staff of the SEC and must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction. Under no circumstances may this prospectus be used for any offer to resell or any resale or other transfer in connection with a distribution of the New Notes. In the event that Avista Corp.'s belief is not correct, Holders of the New Notes who transfer New Notes in violation of the prospectus delivery provisions of the Securities Act and without an exemption from registration thereunder may incur liability thereunder. Avista Corp. does not assume or indemnify Holders against such liability. Each broker-dealer that receives New Notes for its own account in exchange for Old Notes which were acquired by such broker-dealer as a result of market-making activities or other trading activities must, and must agree to, deliver a prospectus in connection with any resale of such New Notes. This prospectus may be used for such purpose. Any such broker-dealer may be deemed to be an "underwriter" within the meaning of the Securities Act. The foregoing interpretation of the staff of the SEC does not apply to, and this prospectus may not be used in connection with, the resale by any broker-dealer of any New Notes received in exchange for an unsold allotment of Old Notes purchased directly from Avista Corp. Avista Corp. has not entered into any arrangement or understanding with any person to distribute the New Notes to be received in the Exchange Offer. The Exchange Offer is not being made to, nor will Avista Corp. accept tenders for exchange from, Holders of Old Notes in any jurisdiction in which the Exchange Offer or the acceptance thereof would not be in compliance with the securities or blue sky laws of such jurisdiction. See PLAN OF DISTRIBUTION. TERMS OF THE EXCHANGE OFFER Upon the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal, Avista Corp. will accept any and all Old Notes properly tendered and not withdrawn prior to 5:00 p.m., New York City time, on the Expiration Date. Avista Corp. will issue $1,000 in principal amount of New Notes in exchange for each $1,000 in principal amount of outstanding Old Notes surrendered in the Exchange Offer. However, Old Notes may be tendered only in integral multiples of $1,000. The form and terms of the New Notes will be the same as the form and terms of the Old Notes. The New Notes will evidence the same debt as the Old Notes. The New Notes will be issued under and entitled to the benefits of the Indenture pursuant to which the Old Notes were issued. The New Notes will be registered under the Securities Act while the Old Notes were not. As of the date of this prospectus, $400,000,000 in aggregate principal amount of the Old Notes is outstanding. This prospectus, together with the letter of transmittal, is being sent to all registered Holders of the Old Notes. Avista Corp. will be deemed to have accepted validly tendered Old Notes when, as and if Avista Corp. shall have given oral (promptly confirmed in writing) or written notice thereof to the Exchange Agent. The Exchange Agent will act as agent for the tendering Holders for the purpose of receiving the New Notes from Avista Corp. Old Notes that are not tendered for exchange in the Exchange Offer will remain outstanding and will be entitled to the rights and benefits such Holders have under the Indenture. If any tendered Old Notes are not accepted for exchange because of an invalid tender, the occurrence of certain other events set forth herein or otherwise, certificates for any such unaccepted Old Notes will be returned, without expense, to the tendering Holder thereof as promptly as practicable after the Expiration Date. Holders who tender Old Notes in the Exchange Offer will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes with respect to the exchange pursuant to the 16 Exchange Offer. Avista Corp. will pay all charges and expenses, other than certain applicable taxes described below, in connection with the Exchange Offer. EXPIRATION DATE; EXTENSIONS; AMENDMENTS TO THE EXCHANGE OFFER The term "Expiration Date," shall mean 5:00 p.m., New York City time on , 2001, unless Avista Corp., in its sole discretion, extends the Exchange Offer, in which case the term "Expiration Date" shall mean the latest date and time to which the Exchange Offer is extended. In order to extend the Exchange Offer, Avista Corp. will notify the Exchange Agent of any extension by oral (promptly confirmed in writing) or written notice and will mail to the registered Holders an announcement thereof, prior to 9:00 a.m., New York City time, on the next business day after the then Expiration Date. Avista Corp. reserves the right, in its sole discretion, (a) to delay accepting any Old Notes, to extend the Exchange Offer or to terminate the Exchange Offer if any of the conditions set forth below under "--Conditions to the Exchange Offer" shall not have been satisfied by giving oral (promptly confirmed in writing) or written notice of such delay, extension or termination to the Exchange Agent or (b) to amend the terms of the Exchange Offer in any manner. Any such delay in acceptances, extension, termination or amendment will be followed as promptly as practicable by oral or written notice thereof to the registered Holders. If the Exchange Offer is amended in a manner determined by Avista Corp. to constitute a material change, Avista Corp. will promptly disclose such amendment by means of a prospectus supplement that will be distributed to the registered Holders of the Old Notes, and Avista Corp. will extend the Exchange Offer for a period of five to ten business days, depending upon the significance of the amendment and the manner of disclosure to the registered Holders, if the Exchange Offer would otherwise expire during such five to ten business day period. Without limiting the manner in which Avista Corp. may choose to make a public announcement of any delay, extension, amendment or termination of the Exchange Offer, Avista Corp. will have no obligation to publish, advertise, or otherwise communicate any such public announcement, other than by making a timely release to an appropriate news agency. Upon satisfaction or waiver of all the conditions to the Exchange Offer, Avista Corp. will accept, promptly after the Expiration Date, all Old Notes properly tendered and will issue the New Notes promptly after acceptance of the Old Notes. See "--Conditions to the Exchange Offer." For purposes of the Exchange Offer, Avista Corp. will be deemed to have accepted properly tendered Old Notes for exchange when, as and if Avista Corp. shall have given oral (promptly confirmed in writing) or written notice thereof to the Exchange Agent. In all cases, issuance of the New Notes for Old Notes that are accepted for exchange pursuant to the Exchange Offer will be made only after timely receipt by the Exchange Agent of a properly completed and duly executed letter of transmittal (or facsimile thereof or an Agent's message in lieu thereof) and all other required documents; provided, however, that Avista Corp. reserves the absolute right to waive any defects or irregularities in the tender or conditions of the Exchange Offer. If any tendered Old Notes are not accepted for any reason set forth in the terms and conditions of the Exchange Offer or if Old Notes are submitted for a greater principal amount or a greater principal amount, respectively, than the Holder desires to exchange, then such unaccepted or non-exchanged Old Notes evidencing the unaccepted portion, as appropriate, will be returned without expense to the tendering Holder thereof as promptly as practicable after the expiration or termination of the Exchange Offer. 17 CONDITIONS TO THE EXCHANGE OFFER Notwithstanding any other term of the Exchange Offer, Avista Corp. will not be required to exchange any New Notes for any Old Notes and may terminate the Exchange Offer before the acceptance of any Old Notes for exchange, if: (a) any action or proceeding is instituted or threatened in any court or by or before any governmental agency with respect to the Exchange Offer which, in Avista Corp.'s reasonable judgment, might materially impair the ability of Avista Corp. to proceed with the Exchange Offer; or (b) any law, statute, rule or regulation is proposed, adopted or enacted, or any existing law, statute, rule or regulation is interpreted by the staff of the SEC, which, in Avista Corp.'s reasonable judgment, might materially impair the ability of Avista Corp. to proceed with the Exchange Offer. If Avista Corp. determines in its sole discretion that any of these conditions are not satisfied, Avista Corp. may (c) refuse to accept any Old Notes and return all tendered Old Notes to the tendering Holders, (d) extend the Exchange Offer and retain all Old Notes tendered prior to the expiration of the Exchange Offer, subject, however, to the rights of Holders who tendered such Old Notes to withdraw their tendered Old Notes, or (e) waive such unsatisfied conditions with respect to the Exchange Offer and accept all properly tendered Old Notes which have not been withdrawn. If such waiver constitutes a material change to the Exchange Offer, Avista Corp. will promptly disclose such waiver by means of a prospectus supplement that will be distributed to the registered Holders, and Avista Corp. will extend the Exchange Offer for a period of five to ten business days, depending upon the significance of the waiver and the manner of disclosure to the registered Holders, if the Exchange Offer would otherwise expire during such five to ten business day period.

Miscellaneous All questions as to the validity, form, eligibility (including time of receipt), acceptance of tendered Old Notes and withdrawal of tendered Old Notes will be determined by Avista Corp. in its sole discretion, which determination will be final and binding. Avista Corp. reserves the absolute right to reject any and all Old Notes not properly tendered or any Old Notes Avista Corp.'s acceptance of which would, in the opinion of counsel for Avista Corp., be unlawful. Avista Corp. also reserves the right to waive any defects, irregularities or conditions of tender as to particular Old Notes. Avista Corp.'s interpretation of the terms and conditions of the Exchange Offer (including the instructions in the letter of transmittal) will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of Old Notes must be cured within such time as Avista Corp. shall determine. Although Avista Corp. intends to notify Holders of defects or irregularities with respect to tenders of Old Notes, none of Avista Corp., the Exchange Agent, or any other person shall incur any liability for failure to give such notification. Tenders of Old Notes will not be deemed to have been made until such defects or irregularities have been cured or waived. Any Old Notes received by the Exchange Agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be 20 returned by the Exchange Agent to the tendering Holders, unless otherwise provided in the letter of transmittal, as soon as practicable following the Expiration Date. By tendering, each Holder or the Person receiving the New Notes, as the case may be will be deemed to represent to Avista Corp. that, among other things, o the New Notes acquired pursuant to the Exchange Offer are being obtained in the ordinary course of business of the Person receiving such New Notes, whether or not such person is the Holder, o neither the Holder nor any such other person is engaged or intends to engage in, or has an arrangement or understanding with any person to participate in, the distribution of such New Notes, and o neither the Holder nor any such other Person is an "affiliate," as defined in Rule 405 of the Securities Act, of Avista Corp. In all cases, issuance of New Notes pursuant to the Exchange Offer will be made only after timely receipt by the Exchange Agent of certificates for the Old Notes tendered for exchange or a timely Book-Entry Confirmation of such Old Notes into the Exchange Agent's account at DTC, a properly completed and duly executed letter of transmittal (or facsimile thereof or Agent's Message in lieu thereof) and all other required documents. If any tendered Old Notes are not accepted for any reason set forth in the terms and conditions of the Exchange Offer or if Old Notes are submitted for a greater principal amount than the Holder desires to exchange, such unaccepted or non-exchanged Old Notes will be returned without expense to the tendering Holder thereof (or, in the case of Old Notes tendered by book-entry transfer into the Exchange Agent's account at DTC pursuant to the book-entry transfer procedures described below, such non-exchanged Old Notes will be credited to an account maintained with DTC) as promptly as practicable after the expiration or termination of the Exchange Offer. Avista Corp. reserves the right in its sole discretion to purchase or make offers for any Old Notes that remain outstanding subsequent to the Expiration Date or, as set forth above under "--Conditions to the Exchange Offer," to terminate the Exchange Offer and, to the extent permitted by applicable law, purchase Old Notes in the open market, in privately negotiated transactions or otherwise. The terms of any such purchases or offers could differ from the terms of the Exchange Offer. WITHDRAWAL OF TENDERS OF OLD NOTES Except as otherwise provided herein, tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration Date.

If Old Notes have been tendered pursuant to book-entry transfer, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Old Notes, in which case a notice of withdrawal will be effective 21 if delivered to the Exchange Agent by any method of delivery described in this paragraph. All questions as to the validity, form and eligibility (including time of receipt) of such notices will be determined by Avista Corp., whose determination shall be final and binding on all parties. Any Old Notes so withdrawn will be deemed not to have been validly tendered for purposes of the Exchange Offer and will be returned to the Holder thereof without cost to such Holder as soon as practicable after withdrawal; and no New Notes will be issued with respect thereto unless the Old Notes so withdrawn are validly retendered. Properly withdrawn Old Notes may be retendered by following one of the procedures described above under "-- Procedures for Tendering" at any time prior to the Expiration Date.

In this description, the words "Avista Corp." refer only to Avista Corporation and not to any of its subsidiaries, except for purposes of financial data determined on a consolidated basis. The Old Notes and the New Notes are sometimes collectively called the "notes". Avista Corp. issued the Old Notes under an indenture, dated as of April 3, 2001, between itself and Chase Manhattan Bank and Trust Company, National Association, as trustee, in a private transaction that was not subject to the registration requirements of the Securities Act. The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The following description is a summary of the material provisions of the indenture relating to the Old Notes. It does not restate the indenture in its entirety. We urge you to read the indenture because it, and not this description, defines your rights as holders of the Old Notes. Some defined terms used in this description but not defined below under "--Certain Definitions" have the meanings assigned to them in the indenture. The registered holder of a note will be treated as the owner of it for all purposes. Only registered holders will have rights under the indenture. RANKING OF THE NOTES The notes: o are general unsecured obligations of Avista Corp.; o are pari passu in right of payment with all existing and future unsecured senior Indebtedness of Avista Corp.; and o are senior in right of payment to all current and future subordinated Indebtedness of Avista Corp., if any. As of April 30, 2001, Avista Corp. had outstanding $203.5 million principal amount of first mortgage bonds, which are secured by a lien on substantially all of Avista Corp.'s utility plant assets (currently owned or hereafter acquired), and $120 million of secured short-term bank debt (secured by a pledge of the stock of Avista Capital) under Credit Facilities with remaining available commitments of $110 million. On May 31, 2001 Avista Corp. renewed its committed line of credit and repaid all outstanding borrowings under that facility. By reason, and to the extent, of these liens, the first mortgage bonds and secured bank debt rank prior to the notes. As of April 30, 2001, Avista Corp. also had outstanding $876 million of unsecured long-term debt and $75.4 million of current portion of unsecured long-term debt. All of such unsecured indebtedness is pari passu in right of payment with the notes. In addition, Avista Corp. had subordinated debentures in a net principal amount outstanding of $103.4 million which are held by the trusts which issued $100 million of outstanding preferred trust securities. The notes are senior in right of payment to these debentures. The amounts of indebtedness discussed in this paragraph relate to Avista Corp. only and not to its subsidiaries. As of the date of this prospectus, all of our subsidiaries are "Restricted Subsidiaries." However, under the circumstances described below under the subheading "--Certain Other Covenants--Designation of Restricted and Unrestricted Subsidiaries", we will be permitted to designate certain of our subsidiaries as "Unrestricted Subsidiaries." Our Unrestricted Subsidiaries will not be subject to many of the restrictive covenants in the indenture. Although its utility operations are conducted directly by Avista Corp., all of the other operations of Avista Corp. are conducted through its subsidiaries. The notes will be effectively subordinated in right of payment to all Indebtedness and other liabilities and commitments (including trade payables and lease obligations) of Avista Corp.'s subsidiaries. Any right of Avista Corp. to receive assets of any of its subsidiaries upon the subsidiary's liquidation or 23 reorganization (and the consequent right of the holders of the notes to participate in those assets) will be effectively subordinated to the claims of that subsidiary's creditors, except to the extent that Avista Corp. is itself recognized as a creditor of the subsidiary, in which case the claims of Avista Corp. would still be subordinate in right of payment to any security in the assets of the subsidiary and any indebtedness of the subsidiary senior to that held by Avista Corp. In addition, Avista Corp.'s ability to access the cash flow of its subsidiaries is subject to substantial restrictions. As of March 31, 2001, Avista Corp.'s subsidiaries had approximately $3.7 million of Indebtedness, $639.4 million of payables and other liabilities, and $9.3 billion of energy commodity liabilities (energy commodity liabilities are held in a portfolio containing $9.5 billion of energy commodity assets) outstanding. PRINCIPAL, MATURITY AND INTEREST Avista Corp. has limited the aggregate principal amount of notes which can be issued under the indenture to $600 million, of which Avista Corp. has issued $400 million aggregate principal amount. Avista Corp. may issue additional notes (the "Additional Notes") from time to time. Any offering of Additional Notes is subject to the covenant described below under the caption "--Certain Other Covenants--Incurrence of Indebtedness and Issuance of Preferred Stock." The notes and any Additional Notes subsequently issued under the indenture would be treated as a single class for all purposes under the indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase. Avista Corp. will issue notes in denominations of $1,000 and integral multiples of $1,000. The notes will mature on June 1, 2008. Interest on the notes will accrue at the rate of 9.75% per annum and will be payable semi-annually in arrears on June 1 and December 1, commencing on December 1, 2001. Avista Corp. will make each interest payment to the holders of record on the immediately preceding May 15 and November 15. Interest on the notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. METHODS OF RECEIVING PAYMENTS ON THE NOTES If a holder has given wire transfer instructions to Avista Corp. at least ten business days prior to the applicable payment date, Avista Corp. will pay all principal, interest and premium, if any, on that holder's notes in accordance with those instructions. All other payments on the notes will be made at the office or agency of the paying agent and registrar for the notes within the City and State of New York unless Avista Corp. elects to make interest payments by check mailed to the holders at their addresses set forth in the register of holders. PAYING AGENT AND REGISTRAR FOR THE NOTES The trustee will initially act as paying agent and registrar. Avista Corp. may change the paying agent or registrar without prior notice to the holders, and Avista Corp. or any of its Subsidiaries may act as paying agent or registrar. TRANSFER AND EXCHANGE A holder may transfer or exchange notes in accordance with the indenture. The registrar and the trustee may require a holder to furnish appropriate endorsements and transfer documents in connection with a transfer of notes. Holders will be required to pay all taxes due on transfer. Avista Corp. is not required to transfer or exchange any note selected for redemption. OPTIONAL REDEMPTION The notes are redeemable in whole or in part, at the option of Avista Corp. at any time, at a redemption price equal to the greater of (i) 100% of the principal amount of the notes being redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the notes being redeemed discounted to the date of redemption on a semiannual basis 24 (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus 50 basis points, plus, for (i) or (ii) above, whichever is applicable, accrued interest on such notes to the date of redemption. "Treasury Yield" means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. "Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of such notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the notes. "Comparable Treasury Price" means, with respect to any redemption date, (i) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third business day preceding such Redemption Date, as set forth in the H.15 Daily Update of the Federal Reserve Bank of New York or (ii) if such release (or any successor release) is not published or does not contain such prices on such business day, the Reference Treasury Dealer Quotation for such redemption date. "H.15(519)" means the weekly statistical release entitled "Statistical Release H.15 (519)", or any successor publication, published by the Board of Governors of the Federal Reserve System. "H.15 Daily Update" means the daily update of H.15(519) available through the worldwide website of the Board of Governors of the Federal Reserve System or any successor site or publication. "Independent Investment Banker" means an independent investment banking institution of national standing appointed by Avista Corp. and reasonably acceptable to the trustee. "Reference Treasury Dealer Quotation" means, with respect to the Reference Treasury Dealer and any redemption date, the average, as determined by the trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount and quoted in writing to the trustee by such Reference Treasury Dealer at 5:00 p.m. on the third business day preceding such redemption date). "Reference Treasury Dealer" means a primary U.S. Government securities dealer in New York City appointed by Avista Corp. and reasonably acceptable to the trustee. Notice of redemption shall be given not less than 15 days nor more than 60 days prior to the date fixed for redemption. Unless Avista Corp. defaults in payment of the Redemption Price (as defined below), from and after the Redemption Date, the notes or portions thereof called for redemption will cease to bear interest, and the holders thereof will have no right in respect to such notes except the right to receive the Redemption Price thereof. Under the procedures set forth above, the price (the "Redemption Price") payable upon the optional redemption at any time of notes is determined by calculating the present value (the "Present Value") at such time of each remaining payment of principal of or interest on such notes and then totaling such Present Values. If the sum of such Present Values is equal to or less than 100% of the principal amount of such notes, the Redemption Price of such notes will be 100% of its principal amount (redemption at par). If the sum of such Present Values is greater than 100% of the principal amount of such notes, the Redemption Price of such notes will be such greater amount (redemption at a premium). In no event may a note be redeemed optionally at less than 100% of its principal amount. The Present Value at any time of a payment of principal of or interest on a note is calculated by applying to such payment the discount rate (the "Discount Rate") applicable to such payment. The Discount Rate applicable at any time to a 25 payment of principal of or interest on a note equals the equivalent yield to maturity at such time of a fixed rate United States treasury security having a maturity comparable to the maturity of such payment plus 50 basis points; such yield being calculated on the basis of the interest rate borne by such United States treasury security and the price at such time of such security. The United States treasury security employed in the calculation of a Discount Rate (a "Relevant Security") as well as the price and equivalent yield to maturity of such Relevant Security will be selected or determined by an investment banker of national standing selected by Avista Corp. which is reasonably acceptable to the trustee. Whether the sum of the Present Values of the remaining payments of principal of and interest on a note to be redeemed optionally will or will not exceed 100% of its principal amount and, accordingly, whether such notes will be redeemed at par or at a premium will depend on the Discount Rate used to calculate such Present Values. Such Discount Rate, in turn, will depend upon the equivalent yield to maturity of a Relevant Security which yield will itself depend on the interest rate borne by, and the price of, the Relevant Security. While the interest rate borne by the Relevant Security is fixed, the price of the Relevant Security tends to vary with interest rate levels prevailing from time to time. In general, if at a particular time the prevailing level of interest rates for a newly issued United States treasury security having a maturity comparable to that of a Relevant Security is higher than the level of interest rates for newly issued United States treasury securities having a maturity comparable to such Relevant Security prevailing at the time the Relevant Security was issued, the price of the Relevant Security will be lower than its issue price. Conversely, if at a particular time the prevailing level of interest rates for a newly issued United States treasury security having a maturity comparable to that of a Relevant Security is lower than the level of interest rates prevailing for newly issued United States treasury securities having a maturity comparable to the Relevant Security at the time the Relevant Security was issued, the price of the Relevant Security will be higher than its issue price. Because the equivalent yield to maturity on a Relevant Security depends on the interest rate it bears and its price, an increase or a decrease in the level of interest rates for newly issued United States treasury securities with a maturity comparable to that of a Relevant Security above or below the levels of interest rates for newly issued United States treasury securities having a maturity comparable to the Relevant Security prevailing at the time of issue of the Relevant Security will generally result in an increase or a decrease, respectively, in the Discount Rate used to determine the Present Value of a payment of principal of or interest on a note. As noted above, if the sum of the Present Values of the remaining payments of principal of and interest on a note proposed to be redeemed is less than its principal amount, such note may only be redeemed at par. MANDATORY REDEMPTION Avista Corp. is not required to make any mandatory redemption or sinking fund payments with respect to the notes. SELECTION AND NOTICE If less than all of the notes are to be redeemed at any time, the trustee will select notes for redemption as follows: (1) if the notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the notes are listed; or (2) if the notes are not listed on any national securities exchange, on a pro rata basis, by lot or by such method as the trustee shall deem fair and appropriate. No portion of a note less than $1,000 will be redeemed. Notices of redemption will be mailed by first class mail at least 15 but not more than 60 days before the redemption date to each holder of notes to be redeemed at its registered address. Notices of redemption may not be conditional. If any note is to be redeemed in part only, the notice of redemption that relates to that note will state the portion of the principal amount of that note that is to be redeemed. A new note in principal amount equal to the unredeemed 26 portion of the original note will be issued in the name of the holder thereof upon cancellation of the original note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on notes or portions of them called for redemption. REPURCHASE AT THE OPTION OF HOLDERS CHANGE OF CONTROL In the event of a Change of Control, each holder of notes will have the right to require Avista Corp. to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000) of that holder's notes pursuant to a Change of Control Offer on the terms set forth in the indenture. In the Change of Control Offer, Avista Corp. will offer a Change of Control Payment in cash equal to 101% of the aggregate principal amount of notes repurchased plus accrued and unpaid interest, if any, thereon, to the date of purchase. Within ten days following any Change of Control, Avista Corp. will mail a notice to each holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase notes on the Change of Control Payment Date specified in the notice, pursuant to the procedures required by the indenture and described in such notice. Avista Corp. will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control. On the Change of Control Payment Date, Avista Corp. will, to the extent lawful: (1) accept for payment all notes or portions of notes properly tendered pursuant to the Change of Control Offer; (2) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions of notes properly tendered; and (3) deliver or cause to be delivered to the trustee the notes so accepted together with an Officers' Certificate stating the aggregate principal amount of notes or portions of notes being purchased by Avista Corp. The paying agent will promptly mail to each holder of notes properly tendered the Change of Control Payment for such notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any; provided that each new note will be in a principal amount of $1,000 or an integral multiple of $1,000. Avista Corp. will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. The provisions described above that require Avista Corp. to make a Change of Control Offer following a Change of Control will be applicable regardless of whether any other provisions of the indenture are applicable. Except as described above with respect to a Change of Control, the indenture does not contain provisions that permit the holders of the notes to require that Avista Corp. repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction. Accordingly, the indenture may not afford the holders of notes protection in all circumstances from the adverse aspects of a highly leveraged transaction, reorganization, restructuring, merger or similar transaction. Avista Corp. will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the indenture applicable to a Change of Control Offer made by Avista Corp. and purchases all notes properly tendered and not withdrawn under such Change of Control Offer. The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of "all or substantially all" of the properties or assets of Avista Corp. and its Subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase "substantially all", there is no precise established 27 definition of the phrase under applicable law. Accordingly, it may be uncertain whether a holder of notes can require Avista Corp. to repurchase those notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of Avista Corp. and its Subsidiaries taken as a whole. ASSET SALES Unless the Rating Condition is satisfied, Avista Corp. will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: (1) Avista Corp. (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of, as determined by Avista Corp.'s Board of Directors and evidenced by a resolution of the Board of Directors set forth in an Officers' Certificate delivered to the trustee before or a reasonable time after such Asset Sale; and (2) at least 75% of the consideration received in such Asset Sale by Avista Corp. or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash: (a) any liabilities (as shown on Avista Corp.'s or such Restricted Subsidiary's most recent balance sheet) of Avista Corp. or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated in right of payment to the notes) that are assumed by the transferee or purchaser of any such assets pursuant to an agreement that releases Avista Corp. or such Restricted Subsidiary from further liability; and (b) any securities, notes or other obligations received by Avista Corp. or any such Restricted Subsidiary from such transferee that are contemporaneously (subject to ordinary settlement periods) converted by Avista Corp. or such Restricted Subsidiary into cash (to the extent of the cash received in that conversion, sale or exchange). Within 360 days after the receipt of any Net Proceeds from an Asset Sale that is consummated at a time when the Rating Condition is not satisfied, Avista Corp. may apply those Net Proceeds: (1) to repay Indebtedness (other than intercompany Indebtedness) of Avista Corp., or a Restricted Subsidiary of Avista Corp., and to correspondingly reduce commitments if such Indebtedness constitutes revolving credit borrowings; (2) to make capital expenditures; or (3) to acquire other long-term assets that are used or useful in a Permitted Business. Pending the final application of any Net Proceeds, Avista Corp. may temporarily reduce revolving credit borrowings or otherwise invest Net Proceeds in any manner that is not prohibited by the indenture. Any Net Proceeds from Asset Sales that are consummated at a time when the Rating Condition is not satisfied that are not applied or invested as provided above in the preceding paragraph will constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds exceeds $15 million, Avista Corp. will make an Asset Sale Offer to all holders of notes (and to all holders of other Indebtedness that is pari passu with the notes and that contains provisions similar to those set forth in the indenture relating to the notes with respect to offers to purchase or redeem with the proceeds of sales of assets) to purchase the maximum principal amount of notes and such other pari passu 28 Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of principal amount (or 100% of the accreted value thereof, in the case of Indebtedness sold at a discount) plus accrued and unpaid interest to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, Avista Corp. may use those Excess Proceeds for any purpose not otherwise prohibited by the indenture. If the aggregate principal amount of notes and other Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, Avista Corp. will allocate the Excess Proceeds on a pro rata basis to the notes and such other Indebtedness tendered, and the trustee will select the notes to be purchased on a pro rata basis based on the principal amount of notes tendered. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. Notwithstanding the foregoing, (1) Avista Corp. may (i) dispose of all or any portion of its transmission assets in one or more RTO Transactions, or (ii) effect, or permit any Restricted Subsidiary to effect, an Asset Sale in which the Capital Stock of Avista Communications, Avista Advantage or Avista Labs (provided such Person is operating substantially the same business as at the date of the indenture) is exchanged for Capital Stock or other securities of another Person if, upon completion thereof, the subject or transferee Person is no longer a Subsidiary of Avista Corp.; provided, however, that if the Rating Condition is not satisfied at the time of such transaction, Avista Corp. shall apply any Net Proceeds therefrom in accordance with the foregoing provisions; provided, further, that if Avista Corp. or any Restricted Subsidiary thereafter disposes of any Capital Stock or other securities or ownership interest in the subject or transferee Person received in, or retained subsequent to, any such transaction, any cash realized therefrom shall be treated as Net Proceeds from an Asset Sale and applied in accordance with the foregoing provisions; and (2) these provisions shall not apply to any Asset Sale which constitutes a transfer, conveyance, sale, lease or other disposition of all or substantially all of Avista Corp.'s properties or assets. See below under "--Certain Other Covenants--Merger, Consolidation or Sale of Assets." Avista Corp. will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with each repurchase of notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sales provisions of the indenture, Avista Corp. will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of the indenture by virtue of such conflict. CERTAIN OTHER COVENANTS Set forth below are certain other covenants contained in the indenture. During any period of time that (i) Moody's and S&P have issued credit ratings of Avista Corp.'s senior unsecured debt of at least Baa2 and BBB, respectively, in each case with a stable or improving outlook and (ii) no Default has occurred and is continuing under the indenture (which we refer to collectively as the "Rating Condition"), Avista Corp. and its Restricted Subsidiaries will not be subject to the provisions of the Indenture described above under "Repurchase at the Option of Holders--Asset Sales", and the provisions described below under "--Restricted Payments", "--Incurrence of Indebtedness and Issuance of Preferred Stock", "--Dividend and Other Payment Restrictions Affecting Subsidiaries", and "--Transactions with Affiliates", and clause (4) of the "--Merger, Consolidation and Sale of Assets" covenant (collectively, the "Suspended Covenants"). If Avista Corp. and its Restricted Subsidiaries are not subject to the Suspended Covenants with respect to the notes for any period of time as a result of the preceding sentence and, subsequently, one or both of Moody's and S&P withdraw their ratings or downgrade the ratings assigned to the notes below the specified ratings, then Avista Corp. and each of its Restricted Subsidiaries (except to the extent that any Restricted Subsidiary is not subject to any such covenant pursuant to the terms thereof) will thereafter again be subject to the Suspended Covenants for the benefit of the notes and compliance with the Suspended Covenants with respect to Restricted Payments made after the time of such withdrawal or downgrade will be calculated in accordance with the terms of the covenant described below under "--Restricted Payments" as if such covenant had been in effect during the entire period of time from the date of the indenture. RESTRICTED PAYMENTS Unless the Rating Condition is satisfied, Avista Corp. will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly: 29 (1) declare or pay any dividend or make any other payment or distribution on account of Avista Corp.'s Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving Avista Corp. or any of its Restricted Subsidiaries) or to the direct or indirect holders of Avista Corp.'s or any of its Restricted Subsidiaries' Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of Avista Corp. or dividends or distributions to Avista Corp. or a Restricted Subsidiary of Avista Corp.); (2) purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving Avista Corp.) any Equity Interests of Avista Corp. or any Person that beneficially owns, directly or indirectly, a majority of the Capital Stock of Avista Corp.; (3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is subordinated in right of payment to the notes, except a payment of interest or principal at or after the Stated Maturity thereof or a refinancing thereof within one year of the final maturity date thereof; or (4) make any Restricted Investment (all such payments and other actions set forth in these clauses (1) through (4) being collectively referred to as "Restricted Payments"), unless, at the time of and after giving effect to such Restricted Payment: (1) no Default or Event of Default has occurred and is continuing or would occur as a consequence thereof; (2) Avista Corp. would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of the covenant described below under the caption "-- Incurrence of Indebtedness and Issuance of Preferred Stock"; and (3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by Avista Corp. and its Subsidiaries after the date of the indenture (excluding Restricted Payments permitted by clauses (2) through (7) and (9) of the next succeeding paragraph), is less than the sum, without duplication, of: (a) 50% of the Consolidated Net Income of Avista Corp. for the period (taken as one accounting period) from the beginning of the first fiscal quarter commencing prior to the date of the indenture to the end of Avista Corp.'s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit), plus (b) 100% of the aggregate net cash proceeds received by Avista Corp. since the date of the indenture as a contribution to its common equity capital or from the issue or sale of Equity Interests of Avista Corp. (other than Disqualified Stock) or upon the exercise of any options, warrants or other rights to purchase Capital Stock (other than Disqualified Capital Stock) of Avista Corp. or from the issuance or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of Avista Corp. that have been converted into or exchanged for such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of Avista Corp.), plus (c) 100% of the net reduction in any Restricted Investment that was made after the date of the indenture resulting from payments of interest on Indebtedness, dividends, repayment of loans or advances, or other transfers of assets, in each case to Avista Corp. or any Restricted Subsidiary, and the cash return of capital with respect to any Restricted Investment (less the cost of disposition, if any), plus 30 (d) to the extent that any Unrestricted Subsidiary of Avista Corp. is redesignated as a Restricted Subsidiary after the date of the indenture, the fair market value of Avista Corp.'s Investment in such Subsidiary as of the date of such redesignation, plus (e) any amount which previously qualified as a Restricted Payment on account of any Guarantee entered into by Avista Corp. or any Restricted Subsidiary; provided that such Guarantee has not been called upon and the obligation arising under such Guarantee no longer exists; less (f) the after-tax amount of any power and natural gas cost deferrals for the period (taken as one accounting period) from the beginning of the first fiscal quarter commencing prior to the date of the indenture to the end of Avista Corp.'s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment; plus (g) the after-tax amount of any amortization of power and natural gas deferrals for the period (taken as one accounting period) from the beginning of the first fiscal quarter commencing prior to the date of the indenture to the end of Avista Corp.'s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment. So long as no Default has occurred and is continuing or would be caused thereby, the preceding provisions will not prohibit: (1) the payment of any dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the provisions of the indenture; (2) the redemption, repurchase, retirement, defeasance or other acquisition of any subordinated Indebtedness of Avista Corp. or of any Equity Interests of Avista Corp. in exchange for, or out of the net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of Avista Corp.) of, Equity Interests of Avista Corp. (other than Disqualified Stock); provided that the amount of any such net cash proceeds that are utilized for any such redemption, repurchase, retirement, defeasance or other acquisition will be excluded from clause (3)(b) of the preceding paragraph; (3) the defeasance, redemption, repurchase or other acquisition of subordinated Indebtedness of Avista Corp. with the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness; (4) the repurchase, redemption, retirement, refinancing, acquisition for value or payment of any Disqualified Stock in exchange for, or out of the net cash proceeds of, the substantially concurrent issuance of new Disqualified Stock of Avista Corp.; provided that any such new Disqualified Stock: (a) shall have an aggregate liquidation preference that does not exceed the aggregate liquidation preference of the amount so refinanced; (b) has a Weighted Average Life to Maturity greater than the remaining Weighted Average Life to Maturity of the Disqualified Capital Stock being refinanced; and (c) has a Stated Maturity later than the Stated Maturity of the Disqualified Stock being refinanced; (5) the repurchase of any subordinated Indebtedness of Avista Corp. at a purchase price not greater than 101% of the principal amount of such subordinated Indebtedness in the event of a Change of Control pursuant to a provision similar to "Repurchase at the Option of Holders--Change of Control"; provided that prior to consummating any such repurchase, Avista Corp. has made the Change of Control Offer required by the indenture and has repurchased all notes validly tendered for payment in connection with such Change of Control Offer; (6) the repurchase of any subordinated Indebtedness of Avista Corp. at a purchase price not greater than 100% of the principal amount of such Indebtedness in the event of an Asset Sale pursuant to a provision similar 31 to the "--Repurchase at the Option of Holders--Asset Sales" covenant; provided that prior to consummating any such repurchase, Avista Corp. has made the Asset Sale Offer required by the indenture and has repurchased all notes validly tendered for payment in connection with such Asset Sale Offer; (7) repurchases of Capital Stock (or warrants or options convertible into or exchangeable for such Capital Stock) deemed to occur upon exercise of stock options to the extent that shares of such Capital Stock (or warrants or options convertible into or exchangeable for such Capital Stock) represent a portion of the exercise price of such options; (8) the declaration and payment of regular quarterly cash dividends in respect of Avista Corp.'s common stock in a per share amount not to exceed 105% of the quarterly dividend for the immediately preceding calendar quarter, and in respect of Avista Corp.'s preferred stock in an aggregate amount not to exceed $2.5 million per calendar quarter; provided that the aggregate amount of such cash dividends will be included as Restricted Payments for purposes of determining the amount of Restricted Payments that may be made pursuant to clause (3) of the preceding paragraph; or (9) other Restricted Payments by Avista Corp. or any Restricted Subsidiary in an aggregate amount not to exceed $10 million since the date of the indenture. The amount of all Restricted Payments (other than cash) will be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued to or by Avista Corp. or such Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any assets or securities that are required to be valued by this covenant will be determined by the Board of Directors whose resolution with respect thereto shall be delivered to the trustee. INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK Unless the Rating Condition is satisfied, Avista Corp. will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, "incur") any Indebtedness (including Acquired Debt), and Avista Corp. will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that Avista Corp. may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and Avista Corp.'s Restricted Subsidiaries may incur Indebtedness or issue preferred stock, if the Fixed Charge Coverage Ratio for Avista Corp.'s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock is issued would have been at least 2.0 to 1, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the preferred stock or Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period. This covenant will not prohibit the incurrence of any of the following items of Indebtedness (collectively, "Permitted Debt"): (1) the incurrence by Avista Corp. or any of its Restricted Subsidiaries of Indebtedness and letters of credit under one or more Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of Avista Corp. and its Restricted Subsidiaries thereunder) equal to $600 million outstanding at any one time, less principal repayments of term loans and permanent commitment reductions with respect to revolving loans and letters of credit under any Credit Facility (in each case, other than in connection with an amendment, refinancing, refunding, replacement, renewal or modification) made after the date of the Indenture; (2) the incurrence by Avista Corp. or any of its Restricted Subsidiaries of the Existing Indebtedness; (3) the incurrence by Avista Corp. of Indebtedness represented by the notes; 32 (4) the incurrence by Avista Corp. or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance or replace, Indebtedness (other than intercompany Indebtedness) that was permitted by the indenture to be incurred under the first paragraph of this covenant or clauses (2), (3), (8), (11) or (12) of this paragraph; (5) the incurrence by Avista Corp. or any of its Restricted Subsidiaries of intercompany Indebtedness between or among Avista Corp. and any of its Restricted Subsidiaries; provided, however, that: (a) if Avista Corp. is the obligor on such Indebtedness, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the notes; and (b)(i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than Avista Corp. or a Restricted Subsidiary thereof and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either Avista Corp. or a Restricted Subsidiary thereof, shall be deemed, in each case, to constitute an incurrence of such Indebtedness by Avista Corp. or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (5); (6) the incurrence by Avista Corp. or any of its Restricted Subsidiaries of: (a) Hedging Obligations that are incurred for the purpose of fixing or hedging interest rate risk with respect to any floating rate Indebtedness that is permitted by the terms of the indenture to be outstanding; (b) Currency Hedging Obligations relating to Indebtedness of Avista Corp. or any Restricted Subsidiary and/or to obligations to purchase or sell assets or properties; provided that such Currency Hedging Obligations do not increase the Indebtedness or other obligations of Avista Corp. or any Restricted Subsidiary other than as a result of fluctuations in foreign currency exchange rates or by reason of fees, indemnities and compensation payable thereunder; (c) Commodity Price Protection Obligations; provided that such Commodity Price Protection Obligations do not increase the amount of Indebtedness or other obligations of Avista Corp. or any Restricted Subsidiary other than as a result of fluctuations in commodity prices or by reason of fees, indemnities and compensation payable thereunder; and (d) the Guarantee by any Restricted Subsidiary of Avista Corp. of Indebtedness of Avista Corp. if such Restricted Subsidiary guarantees the notes by executing a guarantee and supplemental indenture in the forms prescribed by the indenture; (7) the Guarantee by Avista Corp. or any Subsidiary of Avista Corp. of Indebtedness of a Restricted Subsidiary of Avista Corp. that was permitted to be incurred by another provision of this covenant; (8) Indebtedness of Avista Corp. or any Restricted Subsidiary of Avista Corp., represented by Capital Lease Obligations, or preferred stock of a Restricted Subsidiary issued, or Indebtedness of Avista Corp. or a Restricted Subsidiary incurred or assumed (i) to finance capital expenditures or (ii) in connection with the acquisition or development of real property, plant or equipment or the Capital Stock of a Restricted Subsidiary that owns such property, plant or equipment in each case incurred for the purpose of financing all or any part of the purchase price of such property, plant or equipment or Capital Stock, in each case in an aggregate principal amount (or accreted value, as applicable) at any time outstanding pursuant to this clause (8), including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (8), not to exceed $275 million; (9) Indebtedness incurred to finance power and natural gas cost deferrals pursuant to, and in accordance with, state statutory or public utility commission authorization, in an amount not to exceed the amount of the deferrals so financed; 33 (10) Indebtedness of Avista Corp. or any of its Restricted Subsidiaries arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business; provided, however, that such Indebtedness is extinguished within five business days of incurrence; (11) shares of preferred stock of a Restricted Subsidiary of Avista Corp. issued to Avista Corp. or another Restricted Subsidiary of Avista Corp.; provided that any subsequent transfer of any Capital Stock or any other event that results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such shares of preferred stock (except to Avista Corp. or another Restricted Subsidiary of Avista Corp.) shall be deemed, in each case, to be an issuance of preferred stock that was not permitted by this clause (11); and (12) the incurrence by Avista Corp. or any of its Restricted Subsidiaries of additional Indebtedness (including under a Credit Facility) in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (12), not to exceed $25 million. In addition, Avista Corp. will not incur any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of Avista Corp. unless such Indebtedness is also contractually subordinated in right of payment to the notes pursuant to terms no less favorable to the holders of the notes; provided, however, that no Indebtedness of Avista Corp. shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of Avista Corp. solely by virtue of being unsecured. For purposes of determining compliance with this "Incurrence of Indebtedness and Issuance of Preferred Stock" covenant: (1) in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (12) above, or is entitled to be incurred pursuant to the first paragraph of this covenant, Avista Corp. will be permitted to classify such item of Indebtedness on the date of its incurrence in any manner that complies with this covenant; (2) Indebtedness under Credit Facilities outstanding on the date of the indenture shall be deemed to have been incurred on the date of the indenture in reliance on the exception provided by clause (1) of the definition of Permitted Debt; (3) the accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this covenant; provided, in each such case, that the amount thereof is included in Fixed Charges of Avista Corp. as accrued; and (4) for purposes of determining compliance with any dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency exchange rate in effect on the date that such Indebtedness was incurred. Notwithstanding the foregoing, Avista Corp. will not incur or suffer to exist, or permit any of its Restricted Subsidiaries or Unrestricted Subsidiaries to incur or suffer to exist, any Obligations with respect to an Unrestricted Subsidiary that would violate the provisions set forth in the definition of Unrestricted Subsidiary. Specifically, without limiting the generality of the foregoing, if an Unrestricted Subsidiary incurs Indebtedness that is not Non-Recourse Debt or any Indebtedness of an Unrestricted Subsidiary ceases to be Non-Recourse Debt, such Unrestricted Subsidiary will then cease to be an Unrestricted Subsidiary for purposes of the indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of Avista Corp. as of such date. 34 LIENS Avista Corp. will not and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any consensual Lien of any kind securing Indebtedness or trade payables (other than Permitted Liens) upon any of their property or assets, now owned or hereafter acquired, unless all payments due under the indenture and the notes are secured on an equal and ratable basis with the obligations so secured until such time as such obligations are no longer secured by a Lien; provided, however, that Avista Corp. and its Restricted Subsidiaries may incur other Liens to secure Indebtedness or trade payables as long as the sum of (x) the amount of outstanding Indebtedness and trade payables secured by Liens incurred pursuant to this proviso plus (y) the Attributable Debt with respect to all outstanding leases in connection with Sale/Leaseback Transactions entered into pursuant to the second paragraph of the covenant described below under the caption "--Sale and Leaseback Transactions", does not exceed $25 million. DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES Unless the Rating Condition is satisfied, Avista Corp. will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: (1) pay dividends or make any other distributions on its Capital Stock to Avista Corp. or any of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to Avista Corp. or any of its Restricted Subsidiaries; (2) make loans or advances to Avista Corp. or any of its Restricted Subsidiaries; or (3) transfer any of its properties or assets to Avista Corp. or any of its Restricted Subsidiaries. However, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of: (1) Existing Indebtedness and Indebtedness under Credit Facilities as in effect on the date of the indenture and any amendments, modifications, restatements, renewals, increases, supplements, refundings, restructurings (including rate increases), replacements or refinancings thereof, provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, restructurings, replacement or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in such Indebtedness, as in effect on the date of the indenture; (2) the indenture and the notes; (3) applicable law or any requirement of any regulatory body; (4) any instrument governing Indebtedness or Capital Stock of a Person acquired by Avista Corp. or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the indenture to be incurred; (5) customary non-assignment provisions of (a) any leases governing a leasehold interest, (b) any supply, license or other agreement entered into in the ordinary course of business of Avista Corp. or any of its Restricted Subsidiaries, or (c) any security agreement relating to a Lien incurred pursuant to clause (10) of the definition of Permitted Liens; 35 (6) purchase money obligations for property acquired in the ordinary course of business that impose restrictions on the property so acquired of the nature described in clause (3) of the preceding paragraph; (7) any agreement for the sale or other disposition of a Restricted Subsidiary or assets that restricts distributions by that Subsidiary or of such assets pending such sale or other disposition; (8) Permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced; (9) Liens securing Indebtedness that limit the right of the debtor to dispose of the assets subject to such Lien; and (10) provisions with respect to the disposition or distribution of assets or property in asset sale agreements entered into in the ordinary course of business. MERGER, CONSOLIDATION OR SALE OF ASSETS Avista Corp. may not, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not Avista Corp. is the surviving corporation); or (2) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties or assets of Avista Corp. and its Restricted Subsidiaries taken as a whole, in one or more related transactions, to another Person; unless: (1) either: (a) Avista Corp. is the surviving corporation; or (b) the Person formed by or surviving any such consolidation or merger or to which such sale, assignment, transfer, conveyance or other disposition shall have been made is either (i) a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia or (ii) a partnership or limited liability company organized or existing under the laws of the United States, any state thereof or the District of Columbia, in either case, that has at least one Restricted Subsidiary that is a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia which corporation becomes a co-issuer of the notes pursuant to a supplemental indenture in form reasonably satisfactory to the trustee; (2) the Person formed by or surviving any such consolidation or merger (if other than Avista Corp.) or the Person to which such sale, assignment, transfer, conveyance or other disposition shall have been made assumes all the obligations of Avista Corp. under the notes and, the indenture pursuant to agreements in form reasonably satisfactory to the trustee; (3) immediately after such transaction no Default or Event of Default exists; and (4) either: (a) Avista Corp. or the Person formed by or surviving any such consolidation or merger (if other than Avista Corp.), or to which such sale, assignment, transfer, conveyance or other disposition shall have been made will, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, be permitted to incur at least $1.00 of additional Indebtedness, either pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of the covenant described above under the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock" or because the Rating Condition is then satisfied; or 36 (b) on the date of such transaction after giving pro forma effect thereto and any related financing transactions, as if the same had occurred at the beginning of the applicable four-quarter period, the pro forma Fixed Charge Coverage Ratio of the surviving Person (if other than Avista Corp.) will exceed the actual Fixed Charge Coverage Ratio of Avista Corp. as of such date. In addition, Avista Corp. may not, directly or indirectly, lease all or substantially all of its properties or assets, in one or more related transactions, to any other Person. TRANSACTIONS WITH AFFILIATES Unless the Rating Condition is satisfied, Avista Corp. will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (each, an "Affiliate Transaction"), unless: (1) the terms of such Affiliate Transaction or series of related Affiliate Transactions are no less favorable to Avista Corp. or such Restricted Subsidiary, as the case may be, than those that would be obtainable in a comparable transaction or series of related transactions in arm's-length dealings with an unrelated third party; and (2) Avista Corp. delivers to the trustee (i) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10 million, a resolution of the Board of Directors set forth in an Officers' Certificate certifying that such Affiliate Transaction complies with clause (l) above and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors and (ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25 million, a written opinion of a nationally recognized investment banking, accounting or appraisal firm stating that such transaction or series of transactions is fair to the holders from a financial point of view. The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraph: (1) any employment, compensation or indemnification arrangement entered into by Avista Corp. or any of its Restricted Subsidiaries in the ordinary course of business with employees, directors, officers or consultants; (2) loans or advances to officers, directors, consultants and employees in the ordinary course of business or guarantees in respect thereof or otherwise made on their behalf (including any payments on such guarantees); (3) any redemption of Capital Stock held by employees upon death, disability or termination of employment at a price not in excess of the fair market value thereof; (4) the grant of stock options or similar rights to employees and directors of Avista Corp.; (5) payment of reasonable directors fees; (6) transactions between or among Avista Corp. and/or its Restricted Subsidiaries; and (7) Restricted Payments and Permitted Investments that are permitted by the provisions of the indenture described above under the caption "--Restricted Payments." 37 SALE AND LEASEBACK TRANSACTIONS Avista Corp. will not, and will not permit any of its Restricted Subsidiaries to, enter into any Sale/Leaseback Transaction with respect to any property owned on the date of the indenture or thereafter acquired unless: (1) Avista Corp. or such Restricted Subsidiary would be entitled to create a Lien on such property securing Indebtedness in an amount at least equal to the Attributable Debt with respect to such transaction without equally and ratably securing the notes pursuant to the covenant described above under the caption "--Liens"; (2) the Net Proceeds of the sale are at least equal to the fair market value (as determined by the Board of Directors) of the property sold and Avista Corp. or such Restricted Subsidiary applies an amount in cash equal to the net proceeds of such sale to the retirement, within 180 days of the effective date of any such arrangement, of Indebtedness of Avista Corp. or a Restricted Subsidiary or purchases other property having a fair market value at least equal to the fair market value of the assets or property sold in such transactions; or (3) such Sale/Leaseback Transaction is between Avista Corp. and any of its Restricted Subsidiaries or between any Restricted Subsidiaries of Avista Corp. In addition to the transactions permitted pursuant to the preceding paragraph, Avista Corp. or any Restricted Subsidiary may enter into any other Sale/Leaseback Transaction as long as the sum of: (a) the Attributable Debt with respect to such Sale/Leaseback Transaction and all other Sale/Leaseback Transactions entered into pursuant to this proviso, plus (b) the amount of outstanding Indebtedness secured by Liens incurred pursuant to the final proviso to the covenant described under "--Liens", does not exceed $25 million. DESIGNATION OF RESTRICTED AND UNRESTRICTED SUBSIDIARIES The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate fair market value of all outstanding Investments owned by Avista Corp. and its Restricted Subsidiaries in the Subsidiary so designated will be deemed to be an Investment made as of the time of such designation and will either reduce the amount available for Restricted Payments under the first paragraph of the covenant described above under the caption "--Restricted Payments" or reduce the amount available for future Investments under one or more clauses of the definition of Permitted Investments, or both, as Avista Corp. shall determine. That designation will be permitted only if such Investment would be permitted at that time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default. Any designation by the Board of Directors shall be evidenced to the trustee by filing with the trustee a certified copy of the board resolution giving effect to the designation and an Officer's Certificate certifying that the designation complied with these conditions and was permitted by the "Restricted Payments" covenant. If, at any time, any Unrestricted Subsidiary would fail to meet the requirements of the definition of an Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of the Indenture and any Indebtedness of the Subsidiary will be deemed to be incurred by a Restricted Subsidiary of Avista Corp. as of that date (and, if such Indebtedness is not permitted to be incurred as of that date under the covenant describes under the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock", Avista Corp. will be in default of such covenant). 38 The Board of Directors of Avista Corp. may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of Avista Corp. of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will be permitted only if (i) such Indebtedness is permitted under the covenant described under the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock", calculated on a pro forma basis as if the designation had occurred at the beginning of the four-quarter period, and (ii) no Default or Event of Default would be in existence following the designation. REPORTS Whether or not required by the rules and regulations of the SEC, so long as any notes are outstanding, Avista Corp. will furnish to the holders of notes, within the time periods specified in the SEC's rules and regulations: (1) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" and, with respect to the annual information only, a report on the annual financial statements by Avista Corp.'s certified independent accountants; and (2) all current reports that would be required to be filed with the SEC on Form 8-K. In addition, whether or not required by the rules and regulations of the SEC, Avista Corp. will file a copy of all of the information and reports referred to in clauses (1) and (2) above with the SEC for public availability within the time periods specified in the SEC's rules and regulations (unless the SEC will not accept such a filing) and make such information available to securities analysts and prospective investors upon request. Avista Corp. has also agreed that, for so long as any Old Notes remain outstanding, it will furnish to the holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. EVENTS OF DEFAULT AND REMEDIES Each of the following is an Event of Default: (1) default continued for 30 days in the payment when due of interest on, the notes; (2) default in payment when due of the principal of, or premium, if any, on the notes; (3) failure by Avista Corp. or any of its Restricted Subsidiaries to comply with any of the provisions described under the captions"--Repurchase at the Option of Holders--Change of Control", "--Repurchase at the Option of Holders--Assets Sales" or "Certain Other Covenants--Merger, Consolidation or Sale of Assets;" (4) default in performance of any other agreements in the indenture or in the notes for 30 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 on the notes then outstanding; (5) there shall have occurred either (i) a default by Avista Corp. or any Restricted Subsidiary under any instrument or instruments under which there is or may be secured or evidenced any Indebtedness of Avista Corp. or any Restricted Subsidiary of Avista Corp. (other than the notes) having an outstanding principal amount of $25 million or more that has caused the holders thereof to declare such Indebtedness to be due and payable prior to its maturity or (ii) a default by Avista Corp. or any Restricted Subsidiary 39 in the payment at maturity of the principal under any such instrument, and such unpaid portion exceeds $25 million and is not paid, or such default is not cured or waived, within any grace period applicable thereto, unless such acceleration is rescinded or annulled or such Indebtedness is discharged within 20 days of Avista Corp. or a Restricted Subsidiary becoming aware of such default; provided, however, that this clause (5) shall not apply to any default on Non-Recourse Debt; (6) any final judgment or order for the payment of money shall be rendered against Avista Corp., or any Restricted Subsidiary of Avista Corp. that is a Significant Subsidiary, in an amount in excess of $25 million and shall not be discharged, and there shall be any period of 30 consecutive days following entry of the final judgment or order in excess of $25 million during which a stay of enforcement of such final judgment or order, by reason of a pending appeal or otherwise, shall not be in effect; (7) certain events of bankruptcy or insolvency with respect to Avista Corp. or any Restricted Subsidiary of Avista Corp. that is a Significant Subsidiary; and (8) except as permitted by the indenture, any guarantee of the notes is held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any guarantor, or any Person acting on behalf of any guarantor, shall deny or disaffirm its obligations under such guarantor's guarantee of the notes. In the case of an Event of Default arising from certain events of bankruptcy or insolvency, with respect to Avista Corp. or any Restricted Subsidiary that is a Significant Subsidiary of Avista Corp., all outstanding notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the trustee or the holders of at least 25% in principal amount of the then outstanding notes may declare all the notes to be due and payable immediately. Holders of the notes may not enforce the indenture or the notes except as provided in the indenture. Subject to certain limitations, holders of a majority in principal amount of the then outstanding notes may direct the trustee in its exercise of any trust or power. The trustee may withhold from holders of the notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest if it determines that withholding notice is in their interest. The holders of a majority in aggregate principal amount of the notes then outstanding by notice to the trustee may on behalf of the holders of all of the notes waive any existing Default or Event of Default and its consequences under the indenture except a continuing Default or Event of Default in the payment of interest on, premium, if any, or the principal of, the notes. Avista Corp. is required to deliver to the trustee annually a statement regarding compliance with the indenture. Upon becoming aware of any Default or Event of Default, Avista Corp. is required to deliver to the trustee a statement specifying such Default or Event of Default. NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS No director, officer, employee, incorporator, controlling person or stockholder of Avista Corp., as such, shall have any liability for any obligations of Avista Corp. under the notes or the indenture, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of notes by accepting a note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the notes. The waiver may not be effective to waive liabilities under the federal securities laws. LEGAL DEFEASANCE AND COVENANT DEFEASANCE Avista Corp. may, at its option and at any time, elect to have all of its obligations discharged with respect to all or a portion of the outstanding notes ("Legal Defeasance") except for: (1) the rights of holders of outstanding notes to receive payments in respect of the principal of, or interest or premium, if any, on such notes, when such payments are due from the trust referred to below; 40 (2) Avista Corp.'s obligations with respect to the notes concerning issuing temporary notes, registration of notes, mutilated, destroyed, lost or stolen notes and the maintenance of an office or agency for payment and money for security payments held in trust; (3) the rights, powers, trusts, duties and immunities of the trustee, and Avista Corp.'s obligations in connection therewith; and (4) the Legal Defeasance provisions of the indenture. In addition, Avista Corp. may, at its option and at any time, elect to have the obligations of Avista Corp. released with respect to certain covenants that are described in the indenture ("Covenant Defeasance") and thereafter any omission to comply with those covenants shall not constitute a Default or Event of Default with respect to the notes. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, rehabilitation and insolvency events) described under "-Events of Default" will no longer constitute an Event of Default with respect to the notes. In order to exercise either Legal Defeasance or Covenant Defeasance: (1) Avista Corp. must irrevocably deposit with the trustee, in trust, for the benefit of the holders of the notes (or, in the case of Legal Defeasance, a specified principal amount thereof), cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants to pay the principal of, premium, if any, and interest on the notes (or in the case of Legal Defeasance, such specified principal amount thereof) on the stated maturity or prior Redemption Date thereof, as the case may be, (2) in the case of Legal Defeasance, Avista Corp. shall have delivered to the trustee: (a) an opinion of counsel in the United States reasonably acceptable to the trustee confirming that (i) Avista Corp. has received from, or there has been published by, the Internal Revenue Service a ruling or (ii) since the date of the indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the holders of the outstanding notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; or (b)(i) an instrument wherein Avista Corp., notwithstanding the satisfaction and discharge of its Indebtedness in respect of the notes or a portion of the principal amount thereof, shall assume the obligation (which shall be absolute and unconditional) to irrevocably deposit with the trustee such additional sums of money, if any, or additional Government Securities, if any, or any combination thereof, at such time or times, as shall be necessary, together with the money and/or Government Securities theretofore so deposited, to pay when due the principal of and premium, if any, and interest due and to become due on such notes or portions thereof, provided, however, that such instrument may state that the obligation of Avista Corp. to make additional deposits as aforesaid shall arise only upon the delivery to Avista Corp. by the trustee of a notice asserting the deficiency and showing the calculation thereof and shall continue only until Avista Corp. shall have delivered to the trustee a further opinion of an independent public accountant of nationally recognized standing to the effect that no such deficiency exists and showing the calculation of the sufficiency of the deposits then held by the trustee; and (ii) an opinion of recognized tax counsel in the United States reasonably acceptable to the trustee to the effect that the holders of the outstanding notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 41 (3) in the case of Covenant Defeasance, Avista Corp. shall have delivered to the trustee an opinion of counsel reasonably acceptable to the trustee confirming that the holders of the outstanding notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; (4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit; (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than the indenture) to which Avista Corp. or any of it Subsidiaries is a party or by which Avista Corp. or any of its Subsidiaries is bound; (6) Avista Corp. must deliver to the trustee an opinion of counsel to the effect that (assuming that no holder of any notes would be considered an insider of Avista Corp. under applicable bankruptcy or insolvency law) after the 123rd day following the deposit, the trust funds will not constitute a "voidable preference" under Section 547 of the Bankruptcy Code; (7) Avista Corp. must deliver to the trustee an Officers' Certificate stating that the deposit was not made by Avista Corp. with the intent of preferring the holders of notes over the other creditors of Avista Corp. or with the intent of defeating, hindering, delaying or defrauding creditors of Avista Corp. or others; and (8) Avista Corp. must deliver to the trustee an Officers' Certificate and an opinion of counsel (with usual and customary exceptions acceptable to the trustee), each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. AMENDMENT, SUPPLEMENT AND WAIVER Except as provided in the next two succeeding paragraphs, the indenture or the notes may be amended or supplemented with the consent of the holders of at least a majority in principal amount of the notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes), and any existing default or compliance with any provision of the indenture or the notes may be waived with the consent of the holders of a majority in principal amount of the then outstanding notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes). Without the consent of each holder affected, an amendment or waiver may not (with respect to any notes held by a non-consenting holder): (1) reduce the principal amount of notes whose holders must consent to an amendment, supplement or waiver; (2) reduce the principal of or change the fixed maturity of any note; (3) reduce the rate of or change the time for payment of interest on any note; (4) waive a Default or Event of Default in the payment of principal of, or interest or premium, if any, on the notes (except a rescission of acceleration of the notes by the holders of at least a majority in aggregate principal amount of the then outstanding notes and a waiver of the payment default that resulted from such acceleration); (5) make any note payable in money other than that stated in the notes; (6) make any change in the provisions of the indenture relating to waivers of past Defaults or the rights of holders of notes to receive payments of principal of, or interest or premium, if any, on the notes; and (7) make any change in the preceding amendment and waiver provisions. 42 Notwithstanding the preceding, without the consent of any holder of notes, Avista Corp. and the trustee may amend or supplement the indenture or the notes: (1) to cure any ambiguity, defect or inconsistency; (2) to provide for uncertificated notes in addition to or in place of certificated notes; (3) to provide for the assumption of Avista Corp.'s obligations to holders of notes in the case of a merger or consolidation or sale of all or substantially all of Avista Corp.'s assets; (4) to make any change that would provide any additional rights or benefits to the holders of notes or that does not adversely affect the legal rights under the indenture of any such holder; (5) to comply with requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act, or (6) to evidence and provide the acceptance of the appointment of a successor trustee under the indenture. SATISFACTION AND DISCHARGE The indenture will be discharged and will cease to be of further effect as to all notes issued thereunder except as to: (1) Avista Corp.'s right to redeem the notes at its option; (2) substitution of apparently mutilated, defaced, destroyed, lost or stolen notes; (3) rights of holders to receive payment of principal of and premium, if any, and interest on the notes; (4) rights, obligations an immunity of the trustee under the indenture; and (5) rights of the holder of notes with respect to any property deposited with the trustee payable to all or any of them, if: (1) either (a) all notes that have been authenticated (except lost, stolen or destroyed notes that have been replaced or paid and notes for whose payment money has theretofore been deposited in trust and thereafter repaid to Avista Corp.) have been delivered to the trustee for cancellation; or (b) a Legal Defeasance has been effected with respect to all notes that have not been so delivered; (2) no Default or Event of Default shall have occurred and be continuing on the date Legal Defeasance has occurred or shall occur as a result of such Legal Defeasance and such Legal Defeasance will not result in a breach or violation of, or constitute a default under, any other material instrument to which Avista Corp. is a party or by which Avista Corp. is bound; (3) Avista Corp. has paid or caused to be paid all sums payable by it under the indenture; and (4) Avista Corp. has delivered irrevocable instructions to the trustee under the indenture to apply the deposited money toward the payment of the notes at the maturity date of the notes. In addition, Avista Corp. must deliver an Officers' Certificate and an Opinion of Counsel to the trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 43 CONCERNING THE TRUSTEE If the trustee becomes a creditor of Avista Corp., the indenture limits its right to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue or resign. The holders of a majority in principal amount of the then outstanding notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee, subject to certain exceptions. The indenture provides that in case an Event of Default shall occur and be continuing, the trustee will be required, in the exercise of its power, to use the degree of care of a prudent man in the conduct of his own affairs. Subject to such provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any holder of notes, unless such holder shall have offered to the trustee security and indemnity satisfactory to it against any loss, liability or expense. BOOK-ENTRY, DELIVERY AND FORM The New Notes initially will be represented by one or more notes in registered, global form without interest coupons (collectively, the "Global Notes"). Upon issuance, the Global Notes will be deposited upon issuance with the trustee as custodian for The Depository Trust Company ("DTC"), in New York, New York, and registered in the name of DTC or its nominee, in each case for credit to an account of a direct or indirect participant in DTC as described below. Except as set forth below, the Global Notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Notes may not be exchanged for notes in certificated form except in the limited circumstances described below. See "--Exchange of Global Notes for Certificated Notes." Except in the limited circumstances described below, owners of beneficial interests in the Global Notes will not be entitled to receive physical delivery of notes in certificated form. In addition, transfers of beneficial interests in the Global Notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of the Euroclear System ("Euroclear") and Clearstream Banking ("Clearstream")), which may change from time to time. DEPOSITORY PROCEDURES The following description of the operations and procedures of DTC, Euroclear and Clearstream are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them from time to time. Avista Corp. takes no responsibility for these operations and procedures and urges investors to contact the system or their participants directly to discuss these matters. DTC has advised Avista Corp. that DTC is a limited-purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the Uniform Commercial Code and a "Clearing Agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities for its participating organizations (collectively, the "Participants") and to facilitate the clearance and settlement of transactions in those securities between Participants through electronic book-entry changes in accounts of its Participants. The Participants include securities brokers and dealers (including the initial purchasers), banks, trust companies, clearing corporations and certain other organizations. Access to DTC's system is also available to other entities such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Participant, either directly or indirectly (collectively, the "Indirect Participants"). Persons who are not Participants may beneficially own securities held by or on behalf of DTC only through the Participants or the Indirect Participants. The ownership interests in, and transfers of ownership interests in, each security held by or on behalf of DTC are recorded on the records of the Participants and Indirect Participants. DTC has also advised Avista Corp. that, pursuant to procedures established by it: 44 (1) Upon deposit of the Global Notes representing the Old Notes, DTC credited the accounts of Participants designated by the initial purchasers of the Old Notes with portions of the principal amount of such Global Notes; and (2) ownership of interests in the Global Notes representing Old Notes are, and ownership of interests in New Notes will be, shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC (with respect to the Participants) or by the Participants and the Indirect Participants (with respect to other owners of beneficial interest in the Global Notes). Investors in the Global Notes who are Participants in DTC's system may hold their interests therein directly through DTC. Investors in the Global Notes who are not Participants may hold their interests therein indirectly through organizations (including Euroclear and Clearstream) which are Participants in such system. Euroclear and Clearstream will hold interests in Global Notes on behalf of their participants through customers' securities accounts in their respective names on the books of their respective depositories, which are Euroclear Bank, S.A./N.V., as operator of Euroclear, and Citibank, N.A., as operator of Clearstream. All interests in a Global Note, including those held through Euroclear or Clearstream, may be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems. The laws of some states require that certain Persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer beneficial interests in a Global Note to such Persons will be limited to that extent. Because DTC can act only on behalf of Participants, which in turn act on behalf of Indirect Participants, the ability of a Person having beneficial interests in a Global Note to pledge such interests to Persons that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests. EXCEPT AS DESCRIBED BELOW, OWNERS OF INTERESTS IN THE GLOBAL NOTES WILL NOT HAVE NOTES REGISTERED IN THEIR NAMES, WILL NOT RECEIVE PHYSICAL DELIVERY OF NOTES IN CERTIFICATED FORM AND WILL NOT BE CONSIDERED THE REGISTERED OWNERS OR "HOLDERS" THEREOF UNDER THE INDENTURE OR THE NOTES FOR ANY PURPOSE. Payments in respect of the principal of, and interest and premium, if any, on a Global Note registered in the name of DTC or its nominee, will be payable to DTC in its capacity as the registered Holder under the indenture. Under the terms of the indenture, Avista Corp. and the trustee will treat the Persons in whose names the notes, including the Global Notes, are registered as the owners thereof for the purpose of receiving payments and for all other purposes. Consequently, neither Avista Corp., the trustee nor any agent of Avista Corp. or the trustee has or will have any responsibility or liability for: (1) any aspect of DTC's records or any Participant's or Indirect Participant's records relating to or payments made on account of beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any of DTC's records or any Participant's or Indirect Participant's records relating to the beneficial ownership interests in the Global Notes; or (2) any other matter relating to the actions and practices of DTC or any of its Participants or Indirect Participants. DTC has advised Avista Corp. that its current practice, upon receipt of any payment in respect of securities (including principal and interest), is to credit the accounts of the relevant Participants with the payment on the payment date unless DTC has reason to believe it will not receive payment on such payment date. Each relevant Participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the relevant security as shown on the records of DTC. Payments by the Participants and the Indirect Participants to the beneficial owners of notes will be governed by standing instructions and customary practices and will be the responsibility of the Participants or the Indirect Participants and will not be the responsibility of DTC, the trustee or Avista Corp. Neither Avista Corp. nor the trustee will be liable for any delay by DTC or any of its Participants in identifying the beneficial owners of the notes, and Avista Corp. and the trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes. 45 DTC has also advised Avista Corp. that, transfers between Participants in DTC will be effected in accordance with DTC's procedures, and will be settled in same-day funds and transfers between participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures. Subject to compliance with the applicable transfer and exchange restrictions described herein, cross-market transfers between the Participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC's rules on behalf of Euroclear or Clearstream, as the case may be, by its respective depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant Global Note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream. DTC has advised Avista Corp. that it will take any action permitted to be taken by a Holder of notes only at the direction of one or more Participants to whose account DTC has credited the interests in the Global Notes and only in respect of such portion of the aggregate principal amount of the notes as to which such Participant or Participants has or have given such direction. However, if there is an Event of Default under the notes, DTC reserves the right to exchange the Global Notes for legended notes in certificated form, and to distribute such notes to its Participants. Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. Neither Avista Corp. nor the trustee nor any of their respective agents will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations. EXCHANGE OF GLOBAL NOTES FOR CERTIFICATED NOTES A Global Note is exchangeable for definitive notes in registered certificated form ("Certificated Notes") if: (1) DTC (a) notifies Avista Corp. that it is unwilling or unable to continue as depositary for the Global Notes and Avista Corp. fails to appoint a successor depositary or (b) has ceased to be a clearing agency registered under the Exchange Act and Avista Corp. fails to appoint a successor depositary; (2) Avista Corp., at its option, notifies the trustee in writing that it elects to cause the issuance of the Certificated Notes; or (3) there shall have occurred and be continuing a Default or Event of Default with respect to the notes. In addition, beneficial interests in a Global Note may be exchanged for Certificated Notes upon prior written notice given to the trustee by or on behalf of DTC in accordance with the indenture. In all cases, Certificated Notes delivered in exchange for any Global Note or beneficial interests in Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of DTC (in accordance with its customary procedures). Any such exchange will be effected through the DTC Deposit/Withdraw at Custodian system and an appropriate adjustment will be made to reflect a decrease in the principal amount of the relevant Global Note. SAME DAY SETTLEMENT AND PAYMENT Avista Corp. will make payments in respect of the notes represented by the Global Notes (including principal, premium, if any, and interest by wire transfer of immediately available funds to the accounts specified by the Global 46 Note Holder. Avista Corp. will make all payments of principal, interest and premium with respect to Certificated Notes by wire transfer of immediately available funds to the accounts specified by the Holders thereof or, if no such account is specified, by mailing a check to each such Holder's registered address. The notes represented by the Global Notes are expected to trade in DTC's Same-Day Funds Settlement System, and any permitted secondary market trading activity in such notes will, therefore, be required by DTC to be settled in immediately available funds. Avista Corp. expects that secondary trading in any Certificated Notes will also be settled in immediately available funds. Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a Participant in DTC will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised Avista Corp. that cash received in Euroclear or Clearstream as a result of sales of interests in a Global Note by or through a Euroclear or Clearstream participant to a Participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC's settlement date. GOVERNING LAW The internal laws of the state of New York will govern and be used to construe the indenture without giving effect to applicable principles of conflicts of law to the extent that the application of the laws of another jurisdiction would be required thereby.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS This section describes the material United States federal income tax consequences of exchanging the Old Notes for New Notes and of owning and disposing of notes. This section reflects the opinion of Thelen Reid & Priest LLP, counsel to Avista Corp. This section applies to you only if you acquired the Old Notes in the offering at the offering price and you hold your notes as capital assets for tax purposes. This section does not apply to you if you are a member of a class of holders subject to special rules, such as: o a dealer in securities or currencies, o a trader in securities that elects to use a mark-to-market method of accounting for your securities holdings, o a bank, o a life insurance company, o a tax-exempt organization, o a person that owns notes that are a hedge or that are hedged against interest rate risks, o a person that owns notes as part of a straddle or conversion transaction for tax purposes, or o a person whose functional currency for tax purposes is not the U.S. dollar. If you purchase notes at a price other than the offering price, the amortizable bond premium or market discount rules may also apply to you. You should consult your tax advisor regarding this possibility. This section is based on the Internal Revenue Code of 1986, as amended, its legislative history, existing and proposed regulations under the Internal Revenue Code, published rulings and court decisions, all as currently in effect. These laws are subject to change, possibly on a retroactive basis. 60 UNITED STATES HOLDERS This subsection describes the tax consequences to a United States holder. You are a United States holder if you are a beneficial owner of a note and you are: o a citizen or resident of the United States, o a domestic corporation or partnership, o an estate whose income is subject to United States federal income tax regardless of its source, or o a trust if a United States court can exercise primary supervision over the trust's administration and one or more United States persons are authorized to control all substantial decisions of the trust. If you are not a United States holder, this subsection does not apply to you and you should refer to "United States Alien Holders" below. Exchange of Old Notes for New Notes An exchange of Old Notes for New Notes will not be a taxable event for federal income tax purposes. Rather, the New Notes will be treated as a continuation of the Old Notes in the hands of a United States holder. As a result, you will not recognize any income, gain or loss for federal income tax purposes upon an exchange of Old Notes for New Notes, and you will have the same tax basis and holding period in the New Notes as you had in the Old Notes. Payments of Interest You will be taxed on interest on your notes as ordinary income at the time you receive the interest or when it accrues, depending on your method of accounting for tax purposes. Purchase, Sale and Retirement of the Notes Your tax basis in your Old Notes generally will be their cost, and your tax basis in any New Notes acquired in the Exchange Offer will be equal to your tax basis in the Old Notes surrendered. You will generally recognize capital gain or loss on the sale or retirement of notes equal to the difference between the amount you realize on the sale or retirement, excluding any amounts attributable to accrued but unpaid interest, and your tax basis in your notes. Capital gain of a noncorporate United States holder is generally taxed at a maximum rate of 20% where the property is held more than one year. UNITED STATES ALIEN HOLDERS This subsection describes the tax consequences to a United States alien holder. You are a United States alien holder if you are the beneficial owner of a note and are, for United States federal income tax purposes: o a nonresident alien individual, o a foreign corporation, o a foreign partnership, o an estate unless its income is subject to United States federal income tax regardless of its source, or o a trust unless a United States court can exercise primary supervision over the trust's administration and one or more United States persons are authorized to control all substantial decisions of the trust. 61 If you are a United States holder, this section does not apply to you. An exchange of Old Notes for New Notes will not constitute a taxable event for federal income tax purposes. Rather, the New Notes will be treated as a continuation of the Old Notes in the hands of a United States alien holder. As a result, you will not recognize any income, gain or loss for federal income tax purposes upon an exchange of Old Notes for New Notes, and you will have the same tax basis and holding period in the New Notes as you had in the Old Notes. Under United States federal income and estate tax law, and subject to the discussion of backup withholding below, if you are a United States alien holder of a note: o we and other U.S. payors generally will not be required to deduct United States withholding tax from payments of principal, premium, if any, and interest to you if, in the case of payments of interest: (1) you do not actually or constructively own 10% or more of the total combined voting power of all classes of stock of Avista Corp. entitled to vote, (2) you are not a controlled foreign corporation that is related to Avista Corp. through stock ownership, (3) your income or gain from the note is not effectively connected with a trade or business that you conduct within the United States, and (4) either (i) you furnish the U.S. payor an Internal Revenue Service Form W-8BEN certifying under penalties of perjury that you are not a United States person, or (ii) the payor can otherwise be satisfied that you are not a United States person by relying on account documentation or other evidence as prescribed in Treasury regulations. However, this requirement will not be considered satisfied if the payor has actual knowledge or reason to know that you are a United States person notwithstanding the certificate or other documentation. o no deduction for any United States federal withholding tax will be made from any gain that you realize on the sale or exchange of your note, including the exchange of Old Notes for New Notes. We and other payors are required to report payments of interest on your notes on Internal Revenue Service Form 1042-S even if the payments are not otherwise subject to information reporting requirements. If you are engaged in a trade or business within the United States and the interest on the note is effectively connected with your United States business, the interest and any gain on the note will not be subject to withholding if you have provided the payor an Internal Revenue Service Form W-8 as prescribed in the Treasury regulations. However, interest on a note that is effectively connected with your United States business will be subject to United States taxation in the same manner as applies to United States holders. In addition, if you are entitled to the benefits of a tax treaty with the United States, interest and gain from the note will generally not be taxable, even if effectively connected with a United States trade or business, unless you also have a permanent establishment in the United States to which the interest or gain is attributable. In order to claim benefits under a tax treaty with the United States, you must furnish an Internal Revenue Service Form W-8BEN to the payor. Further, a note held by an individual who at death is not a citizen or resident of the United States will not be includible in the individual's gross estate for United States federal estate tax purposes if: o the decedent did not actually or constructively own 10% or more of the total combined voting power of all classes of stock of Avista Corp. entitled to vote at the time of death, and o the income on the note would not have been effectively connected with a United States trade or business of the decedent at the same time. 62 BACKUP WITHHOLDING AND INFORMATION REPORTING We and other payors, including brokers, may be required to report to you and to the Internal Revenue Service any payments of principal, premium and interest on your note and the amount of any proceeds from the sale or exchange of your note. As described more fully below, we and other payors may also be required to make "backup withholding" from payments of principal, premium, interest and sales proceeds if you fail to provide an accurate taxpayer identification number or otherwise establish an exemption from backup withholding. Backup withholding is not an additional tax. If you are subject to backup withholding, you may obtain a credit or refund of the amount withheld by filing the required information with the Internal Revenue Service. UNITED STATES HOLDERS In general, if you are a noncorporate United States holder, we and other payors are required to report to the Internal Revenue Service all payments of principal, any premium and interest on your note. In addition, we and other payors are required to report to the Internal Revenue Service any payment of proceeds of the sale of your note before maturity within the United States. Additionally, backup withholding at a rate of 31% will apply to any payments if you fail to provide an accurate taxpayer identification number, or you are notified by the Internal Revenue Service that you have failed to report all interest and dividends required to be shown on your federal income tax returns. UNITED STATES ALIEN HOLDERS In general, payments of principal, premium or interest made by us and other payors to you will not be subject to backup withholding and information reporting, provided that the certification requirements described above under "United States Alien Holders" are satisfied or you otherwise establish an exemption. In general, proceeds of your sale of a note will not be subject to backup withholding or information reporting if: o you furnish your broker an Internal Revenue Service Form W-8BEN certifying under penalties of perjury that you are not a United States person, or o your broker possesses other documentation concerning your account on which the broker is permitted to rely under Treasury regulations to establish that you are a non-United States person, or o you otherwise establish an exemption. If you are not exempted from backup withholding and information reporting under the preceding paragraph: o Backup withholding and information reporting will apply to the proceeds of any sale that you make through the United States office of any broker, foreign or domestic. o Information reporting will also apply to the proceeds of sales that are made through a foreign office of a broker if the proceeds are paid into a United States account, or such proceeds or the confirmation of the sale are mailed to you at a United States address, or if you have opened an account with a United States office of your broker, or regularly communicated with the broker from the United States concerning the sale in question and other sales, or negotiated the sale in question through the broker's United States office. Backup withholding will also apply unless the proceeds of such a sale are paid to an account maintained at a bank or other financial institution located outside the United States. o Information reporting, but not backup withholding, will apply to sales made through a foreign office of a broker that is a United States person, or that is a foreign corporation or partnership controlled by U.S. persons or that derives more than 50% of its income from U.S. 63 business activities over a three-year period as specified in the Treasury regulations. Notwithstanding any withholding certificate or documentary evidence in a broker's possession, a broker who has actual knowledge or reason to know that you are a United States person will be required to make backup withholdings and file information reports with the Internal Revenue Service if the broker is a U.S. person or is a foreign person that has a U.S. connection of the type discussed in the last bullet point of the preceding paragraph. PLAN OF DISTRIBUTION As discussed under THE EXCHANGE OFFER, based on an interpretation of the staff of the SEC, New Notes issued pursuant to the Exchange Offer may be offered for resale and resold or otherwise transferred by any Holder of such New Notes (other than any such Holder which is an "affiliate" of Avista Corp. within the meaning of Rule 405 under the Securities Act and except as otherwise discussed below with respect to Holders which are broker-dealers) without compliance with the registration and prospectus delivery requirements of the Securities Act so long as such New Notes are acquired in the ordinary course of such Holder's business and such Holder has no arrangement or understanding with any person to participate in the distribution (within the meaning of the Securities Act) of such New Notes. Each broker-dealer that receives New Notes for its own account in exchange for Old Notes which were acquired by such broker-dealer as a result of market-making activities or other trading activities must, and must agree to, deliver a prospectus in connection with any resale of such New Notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of New Notes received in exchange for Old Notes where such Old Notes were acquired as a result of market-making activities or other trading activities. Avista Corp. will for a period of 90 days after the Expiration Date make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until _____, 2001, all dealers effecting transactions in the New Notes may be required to deliver a prospectus. New Notes received by broker-dealers for their own account in the Exchange Offer as described above may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the New Notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or at negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such New Notes. Any broker-dealer that resells New Notes that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a distribution of such New Notes may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit on any such resale of New Notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. The interpretation of the staff of the SEC referred to in the first paragraph of this section does not apply to, and this prospectus may not be used in connection with, the resale by any broker-dealer of any New Notes received in exchange for an unsold allotment of Old Notes purchased directly from Avista Corp. Avista Corp. will not receive any proceeds from the issuance of the New Notes pursuant to the Exchange Offer or from any subsequent sale of the New Notes. Avista Corp. has agreed to pay all expenses incident to the Exchange Offer other than commissions or concessions of any brokers or dealers and expenses of counsel for the holders of the New Notes and will indemnify the holders of the New Notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act. 64 WHERE YOU CAN FIND MORE INFORMATION Avista Corp. files annual, quarterly and special reports, proxy statements and other information with the SEC.

INFORMATION NOT REQUIRED IN PROSPECTUS ITEM 20. 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: "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 21. EXHIBITS. Reference is made to the Exhibit Index on p. II-6 hereof. ITEM 22. UNDERTAKINGS. The undersigned Registrant hereby undertakes: (1) 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 II-1 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; (2) To respond to requests for information that is incorporated by reference into the prospectus pursuant to item 4,10(b), 11 or 13 of Form S-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of this registration statement through the date of responding to the request. 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-2 POWER OF ATTORNEY The Registrant hereby appoints each Agent for Service named in this registration statement as its attorney-in-fact to sign in its 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 or her attorney-in-fact with like authority to sign in his or her name and behalf, in any and all capacities stated below, and to file with the Securities and Exchange Commission, any and all such amendments. SIGNATURES Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Spokane and State of Washington on the 31st day of May, 2001.

          2.   Registration Under the Securities Act.

          (a) Except as set forth in Section 2(b) below, the Company agrees to
     file under the Securities Act, as soon as practicable, but no later than 90
     days after the Closing Date, a registration statement relating to an offer
     to exchange (such registration statement, the "Exchange Registration


                                       3



     Statement", and such offer, the "Exchange Offer") any and all of the
     Securities for a like aggregate principal amount of debt securities issued
     by the Company, which debt securities are substantially identical to the
     Securities (and are entitled to the benefits of a trust indenture which is
     substantially identical to the Indenture or is the Indenture and which has
     been qualified under the Trust Indenture Act), except that they have been
     registered pursuant to an effective registration statement under the
     Securities Act and do not contain provisions for the liquidated damages
     contemplated in Section 2(c) below (such new debt securities hereinafter
     called "Exchange Securities"). The Company agrees to use all commercially
     reasonable efforts to cause the Exchange Registration Statement to become
     effective under the Securities Act as soon as practicable, but no later
     than 180 days after the Closing Date. The Exchange Offer will be registered
     under the Securities Act on the appropriate form and will comply with all
     applicable tender offer rules and regulations under the Exchange Act. The
     Company further agrees to use its best efforts to commence and complete the
     Exchange Offer promptly, but no later than 45 days after such registration
     statement has become effective, hold the Exchange Offer open for at least
     30 days and exchange Exchange Securities for all Registrable Securities
     that have been properly tendered and not withdrawn on or prior to the
     expiration of the Exchange Offer. The Exchange Offer will be deemed to have
     been "completed" only if the debt securities received in the Exchange Offer
     by holders other than Restricted Holders are, upon receipt, transferable by
     each such holder without restriction under the Securities Act and the
     Exchange Act and without material restrictions under the blue sky or
     securities laws of a substantial majority of the states of the United
     States of America. The Exchange Offer shall be deemed to have been
     completed upon the earlier to occur of (i) the Company having exchanged the
     Exchange Securities for all outstanding Registrable Securities pursuant to
     the Exchange Offer and (ii) the Company having exchanged, pursuant to the
     Exchange Offer, Exchange Securities for all Registrable Securities that
     have been properly tendered and not withdrawn before the expiration of the
     Exchange Offer, which shall be on a date that is at least 30 days following
     the commencement of the Exchange Offer. The Company agrees (x) to include
     in the Exchange Registration Statement a prospectus for use in any resales
     by any holder of Exchange Securities that is a broker-dealer and (y) to
     keep such Exchange Registration Statement effective for a period (the
     "Resale Period") beginning when Exchange Securities are first issued in the
     Exchange Offer and ending upon the earlier of the expiration of the 180th
     day after the Exchange Offer has been completed or such time as such
     broker-dealers no longer own any Registrable Securities. With respect to
     such Exchange Registration Statement, such holders shall have the benefit
     of the rights of indemnification and contribution set forth in Sections
     6(a), (c), (d) and (e) hereof.

          (b) If (i) on or prior to the time the Exchange Offer is completed,
     existing Commission interpretations are changed such that the debt
     securities received by holders other than Restricted Holders in the
     Exchange Offer are not or would not be, upon receipt, transferable by each
     such holder without restriction under the Securities Act, (ii) the Exchange
     Offer has not been completed within 225 days following the Closing Date or
     (iii) the Exchange Offer is not available to any holder of the Securities,
     the Company shall, in lieu of (or, in the case of clause (iii), in addition
     to) conducting the Exchange Offer contemplated by Section 2(a), file under
     the Securities Act as soon as practicable, but no later than 30 days after
     the time such obligation to file arises, a "shelf" registration statement
     providing for the registration of, and the sale on a continuous or delayed
     basis by the holders of, all of the Registrable Securities, pursuant to
     Rule 415 or any similar rule that may be adopted by the Commission (such
     filing, the "Shelf Registration" and such registration statement, the
     "Shelf Registration Statement"). The Company agrees to use all commercially
     reasonable efforts (x) to cause the Shelf Registration Statement to become


                                       4



     or be declared effective no later than 120 days after such Shelf
     Registration Statement is filed and to keep such Shelf Registration
     Statement continuously effective for a period ending on the earlier of the
     second anniversary of the Effective Time or such time as there are no
     longer any Registrable Securities outstanding, provided, however, that no
     holder shall be entitled to be named as a selling securityholder in the
     Shelf Registration Statement or to use the prospectus forming a part
     thereof for resales of Registrable Securities unless such holder is an
     Electing Holder, and (y) after the Effective Time of the Shelf Registration
     Statement, promptly upon the request of any holder of Registrable
     Securities that is not then an Electing Holder, to take any action
     reasonably necessary to enable such holder to use the prospectus forming a
     part thereof for resales of Registrable Securities, including, without
     limitation, any action necessary to identify such holder as a selling
     securityholder in the Shelf Registration Statement, provided, however, that
     nothing in this Clause (y) shall relieve any such holder of the obligation
     to return a completed and signed Notice and Questionnaire to the Company in
     accordance with Section 3(d)(iii) hereof. The Company further agrees to
     supplement or make amendments to the Shelf Registration Statement, as and
     when required by the rules, regulations or instructions applicable to the
     registration form used by the Company for such Shelf Registration Statement
     or by the Securities Act or rules and regulations thereunder for shelf
     registration, and the Company agrees to furnish to each Electing Holder
     copies of any such supplement or amendment prior to its being used or
     promptly following its filing with the Commission. Notwithstanding the
     foregoing, if the Board of Directors of the Company determines in good
     faith that it is in the best interests of the Company not to disclose the
     existence of or facts surrounding any proposed or pending material
     corporate transaction involving the Company, the Company may allow the
     Shelf Registration Statement to fail to be effective and usable as a result
     of such nondisclosure for up to 60 days during the two year period of
     effectiveness required by Section 2 hereof, but in no event for any period
     in excess of 30 consecutive days.

          (c) In the event that (i) the Company has not filed the Exchange
     Registration Statement or Shelf Registration Statement on or before the
     date on which such registration statement is required to be filed pursuant
     to Section 2(a) or 2(b), respectively, or (ii) such Exchange Registration
     Statement or Shelf Registration Statement has not become effective or been
     declared effective by the Commission on or before the date on which such
     registration statement is required to become or be declared effective
     pursuant to Section 2(a) or 2(b), respectively, or (iii) the Exchange Offer
     has not been completed within 45 days after the initial effective date of
     the Exchange Registration Statement relating to the Exchange Offer (if the
     Exchange Offer is then required to be made) or (iv) any Exchange
     Registration Statement or Shelf Registration Statement required by Section
     2(a) or 2(b) hereof is filed and declared effective but shall thereafter
     either be withdrawn by the Company or shall become subject to an effective
     stop order issued pursuant to Section 8(d) of the Securities Act suspending
     the effectiveness of such registration statement (except as specifically
     permitted herein) without being succeeded immediately by an additional
     registration statement filed and declared effective (each such event
     referred to in clauses (i) through (iv), a "Registration Default" and each
     period during which a Registration Default has occurred and is continuing,
     a "Registration Default Period"), then, as liquidated damages for such
     Registration Default, subject to the provisions of Section 9(b), liquidated
     damages ("Liquidated Damages"), in addition to the Base Interest, shall
     accrue at a per annum rate of 0.25% for the first 90 days of the
     Registration Default Period, at a per annum rate of 0.50% for the second 90
     days of the Registration Default Period, at a per annum rate of 0.75% for


                                       5



     the third 90 days of the Registration Default Period and at a per annum
     rate of 1.0% thereafter for the remaining portion of the Registration
     Default Period.

          (d) The Company shall take all actions necessary or advisable to be
     taken by it to ensure that the transactions contemplated herein are
     effected as so contemplated.

          (e) Any reference herein to a registration statement as of any time
     shall be deemed to include any document incorporated, or deemed to be
     incorporated, therein by reference as of such time and any reference herein
     to any post-effective amendment to a registration statement as of any time
     shall be deemed to include any document incorporated, or deemed to be
     incorporated, therein by reference as of such time.

          relating to expense reimbursement, indemnification and contribution as
          are provided in Section 6 hereof;


                                       13



               (xviii) notify in writing each holder of Registrable Securities
          of any proposal by the Company to amend or waive any provision of this
          Exchange and Registration Rights Agreement pursuant to Section 9(h)
          hereof and of any amendment or waiver effected pursuant thereto, each
          of which notices shall contain the text of the amendment or waiver
          proposed or effected, as the case may be; and

               (xix) comply in all material respects with all applicable rules
          and regulations of the Commission, and make generally available to its

          complying with Section 11(a) of the Securities Act (including, at the
          option of the Company, Rule 158 thereunder).

          (e) In the event that the Company would be required, pursuant to
     Section 3(d)(viii)(F) above, to notify the Electing Holders, the placement
     or sales agent, if any, therefor and the managing underwriters, if any,
     thereof, the Company shall without delay prepare and furnish to each of the
     Electing Holders, to each placement or sales agent, if any, and to each
     such underwriter, if any, a reasonable number of copies of a prospectus
     supplemented or amended so that, as thereafter delivered to purchasers of
     Registrable Securities, such prospectus shall conform in all material
     respects to the applicable requirements of the Securities Act and the Trust
     Indenture Act and the rules and regulations of the Commission thereunder
     and shall not contain an untrue statement of a material fact or omit to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading in light of the circumstances then
     existing. Each Electing Holder agrees that upon receipt of any notice from
     the Company pursuant to Section 3(d)(viii)(F) hereof, such Electing Holder
     shall forthwith discontinue the disposition of Registrable Securities
     pursuant to the Shelf Registration Statement applicable to such Registrable
     Securities until such Electing Holder shall have received copies of such
     amended or supplemented prospectus, and if so directed by the Company, such

     possession of the prospectus covering such Registrable Securities at the
     time of receipt of such notice.

          (f) In the event of a Shelf Registration, in addition to the
     information required to be provided by each Electing Holder in its Notice
     Questionnaire, the Company may require such Electing Holder to furnish to
     the Company such additional information regarding such Electing Holder and
     such Electing Holder's intended method of distribution of Registrable
     Securities as may be required in order to comply with the Securities Act.
     Each such Electing Holder agrees to notify the Company as promptly as
     practicable of any inaccuracy or change in information previously furnished
     by such Electing Holder to the Company or of the occurrence of any event in
     either case as a result of which any prospectus relating to such Shelf
     Registration contains or would contain an untrue statement of a material


                                       14



     fact regarding such Electing Holder or such Electing Holder's intended
     method of disposition of such Registrable Securities or omits to state any
     material fact regarding such Electing Holder or such Electing Holder's
     intended method of disposition of such Registrable Securities required to
     be stated therein or necessary to make the statements therein not
     misleading in light of the circumstances then existing, and promptly to
     furnish to the Company any additional information required to correct and
     update any previously furnished information or required so that such
     prospectus shall not contain, with respect to such Electing Holder or the
     disposition of such Registrable Securities, an untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading in light
     of the circumstances then existing.

          (g) Until the expiration of two years after the Closing Date, the
     Company will not, and will not permit any of its "affiliates" (as defined
     in Rule 144) to, resell any of the Securities that have been reacquired by
     any of them except pursuant to an effective registration statement under
     the Securities Act.

          4.   Registration Expenses.

     the Securities Act, or any preliminary, final or summary prospectus
     contained therein or furnished by the Company to any such holder, Electing
     Holder, agent or underwriter, 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 holder, such
     Electing Holder, such agent and such underwriter for any legal or other
     expenses reasonably incurred by them in connection with investigating or
     defending any such losses, claims, damages, liabilities or actions as such
     expenses are incurred; provided, however, that the Company shall not be
     liable to any such person 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 such registration statement, or preliminary, final or summary
     prospectus, or amendment or supplement thereto, in reliance upon and in
     conformity with written information furnished to the Company by such person
     expressly for use therein; and provided, further, that the Company shall
     not be liable to any such person with respect to any preliminary prospectus
     to the extent that any such loss, claim, damage or liability of such person
     results from the fact that such person participated in a sale of
     Registrable Securities to a person as to whom it shall be established that
     there was not sent or given, at or prior to the written confirmation of
     such sale, a copy of the final prospectus as then amended or supplemented
     if the Company has previously furnished copies thereof in sufficient
     quantity to such person and sufficiently in advance of the time of delivery
     of such Registrable Securities to allow for distribution by such time of
     delivery and the loss, claim, damage or liability of person results from an
     untrue statement or omission of a material fact contained in or omitted
     from the preliminary prospectus which was identified in writing at such
     time to person and corrected in the final prospectus as then amended or
     supplemented and each correction would have cured the defect giving rise to
     such loss, claim, damage or liability.


                                       17



          (b) Indemnification by the Holders and any Agents and Underwriters.
     The Company may require, as a condition to including any Registrable
     Securities in any registration statement filed pursuant to Section 2(b)
     hereof and to entering into any underwriting agreement with respect
     thereto, that the Company shall have received an undertaking reasonably
     satisfactory to it from the Electing Holder of such Registrable Securities
     and from each underwriter named in any such underwriting agreement,
     severally and not jointly, to (i) indemnify and hold harmless the Company,
     and all other holders of Registrable Securities, against any losses,
     claims, damages or liabilities to which the Company or such other holders
     of Registrable Securities may become subject, under the Securities 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 such
     registration statement, or any preliminary, final or summary prospectus
     contained therein or furnished by the Company to any such Electing Holder,
     agent or underwriter, 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 reliance upon and in conformity
     with written information furnished to the Company by such Electing Holder
     or underwriter expressly for use therein, and (ii) reimburse the Company
     for any legal or other expenses reasonably incurred by the Company in
     connection with investigating or defending any such losses, claims,
     damages, liabilities or actions as such expenses are incurred; provided,
     however, that no such Electing Holder shall be required to undertake
     liability to any person under this Section 6(b) for any amounts in excess
     of the dollar amount of the proceeds to be received by such Electing Holder
     from the sale of such Electing Holder's Registrable Securities pursuant to
     such registration.

          (c) Notices of Claims, Etc. Promptly after receipt by an indemnified
     party under subsection (a) or (b) above of written notice of the
     commencement of any action, such indemnified party shall, if a claim in
     respect thereof is to be made against an indemnifying party pursuant to the
     indemnification provisions of or contemplated by this Section 6, notify
     such indemnifying party in writing of the commencement of such action; 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 the indemnification provisions of or contemplated by Section 6(a) or
     6(b) hereof. In case any such action shall be brought against any
     indemnified party and it shall notify an indemnifying party of the
     commencement thereof, such 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 reasonably 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, such
     indemnifying party shall not be liable to such indemnified party 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. No
     indemnifying party shall, without the written consent of the indemnified
     party, effect the settlement or compromise of, or consent to the entry of
     any judgment with respect to, any pending or threatened action or claim in
     respect of which indemnification or contribution may be sought hereunder
     (whether or not the indemnified party is an actual or potential party to
     such action or claim) unless such settlement, compromise or judgment (i)
     includes an unconditional release of the indemnified party from all


                                       18



     liability arising out of such action or claim and (ii) does not include a
     statement as to or an admission of fault, culpability or a failure to act
     by or on behalf of any indemnified party.

          (d) Contribution. If for any reason the indemnification provisions
     contemplated by Section 6(a) or Section 6(b) are unavailable to or
     insufficient to hold harmless an indemnified party 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 fault of the
     indemnifying party and the indemnified party in connection with the
     statements or omissions which resulted in such losses, claims, damages or
     liabilities (or actions in respect thereof), as well as any other relevant
     equitable considerations. The relative fault of such indemnifying party and
     indemnified party shall be determined by reference to, among other things,
     whether the untrue or alleged untrue statement of a material fact or
     omission or alleged omission to state a material fact relates to
     information supplied by such indemnifying party or by such indemnified
     party, and the parties' relative intent, knowledge, access to information
     and opportunity to correct or prevent such statement or omission. The
     parties hereto agree that it would not be just and equitable if
     contributions pursuant to this Section 6(d) were determined by pro rata
     allocation (even if the holders or any agents or underwriters or all of
     them 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 in this Section 6(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 shall be
     deemed to include any legal or other fees or expenses reasonably incurred
     by such indemnified party in connection with investigating or defending any
     such losses, claims, damages, liabilities or actions. Notwithstanding the
     provisions of this Section 6(d), no holder shall be required to contribute
     any amount in excess of the amount by which the dollar amount of the
     proceeds received by such holder from the sale of any Registrable
     Securities (after deducting any fees, discounts and commissions applicable
     thereto) exceeds the amount of any damages which such holder has otherwise
     been required to pay by reason of such untrue or alleged untrue statement
     or omission or alleged omission, and no underwriter shall be required to
     contribute any amount in excess of the amount by which the total price at
     which the Registrable Securities underwritten by it and distributed to the
     public were offered to the public exceeds the amount of any damages which
     such underwriter 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 Securities Act) shall be entitled to contribution from
     any person who was not guilty of such fraudulent misrepresentation. The
     holders' and any underwriters' obligations in this Section 6(d) to
     contribute shall be several in proportion to the principal amount of
     Registrable Securities registered or underwritten, as the case may be, by
     them and not joint.

          (e) The obligations of the Company under this Section 6 shall be in
     addition to any liability which the Company may otherwise have and shall
     extend, upon the same terms and conditions, to each officer, director and
     partner of each holder, agent and underwriter and each person, if any, who
     controls any holder, agent or underwriter within the meaning of the
     Securities Act; and the obligations of the holders and any agents or
     underwriters contemplated by this Section 6 shall be in addition to any
     liability which the respective holder, agent or underwriter may otherwise


                                       19



     have and shall extend, upon the same terms and conditions, to each officer
     and director of the Company (including any person who, with his consent, is
     named in any registration statement as about to become a director of the
     Company) and to each person, if any, who controls the Company within the
     meaning of the Securities Act.

          7.   Underwritten Offerings.

          (a) Selection of Underwriters. If any of the Registrable Securities
     covered by the Shelf Registration are to be sold pursuant to an
     underwritten offering, the managing underwriter or underwriters thereof
     shall be designated by Electing Holders holding a majority in aggregate
     principal amount of the Registrable Securities to be included in such
     offering, provided that such designated managing underwriter or
     underwriters is or are reasonably acceptable to the Company.

          (b) Participation by Holders. Each holder of Registrable Securities
     hereby agrees with each other such holder that no such holder may
     participate in any underwritten offering hereunder unless such holder (i)
     agrees to sell such holder's Registrable Securities on the basis provided
     in any underwriting arrangements approved by the persons entitled hereunder
     to approve such arrangements and (ii) completes and executes all
     questionnaires, powers of attorney, indemnities, underwriting agreements
     and other documents reasonably required under the terms of such
     underwriting arrangements.

          8.   Rule 144.

          The Company covenants to the holders of Registrable Securities that to
the extent it shall be required to do so under the Exchange Act, the Company
shall timely file the reports required to be filed by it under the Exchange Act
or the Securities Act (including the reports under Section 13 and 15(d) of the
Exchange Act referred to in subparagraph (c)(1) of Rule 144 adopted by the
Commission under the Securities Act) and the rules and regulations adopted by
the Commission thereunder, and shall take such further action as any holder of
Registrable Securities may reasonably request, all to the extent required from
time to time to enable such holder to sell Registrable Securities without
registration under the Securities Act within the limitations of the exemption
provided by Rule 144 under the Securities Act, as such Rule may be amended from
time to time, or any similar or successor rule or regulation hereafter adopted
by the Commission. Upon the request of any holder of Registrable Securities in
connection with that holder's sale pursuant to Rule 144, the Company shall
deliver to such holder a written statement as to whether it has complied with
such requirements.

          9.   Miscellaneous.

          (a) No Inconsistent Agreements. The Company represents, warrants,
     covenants and agrees that it has not granted, and shall not grant,
     registration rights with respect to Registrable Securities or any other
     securities which would be inconsistent with the terms contained in this
     Exchange and Registration Rights Agreement.

          (b) Specific Performance. The parties hereto acknowledge that there
     would be no adequate remedy at law if the Company fails to perform any of
     its obligations hereunder and that the Purchasers and the holders from time
     to time of the Registrable Securities may be irreparably harmed by any such
     failure, and accordingly agree that the Purchasers and such holders, in
     addition to any other remedy to which they may be entitled at law or in
     equity, shall be entitled to compel specific performance of the obligations


                                       20



     of the Company under this Exchange and Registration Rights Agreement in
     accordance with the terms and conditions of this Exchange and Registration
     Rights Agreement, in any court of the United States or any State thereof
     having jurisdiction.

          (c) Notices. All notices, requests, claims, demands, waivers and other
     communications hereunder shall be in writing and shall be deemed to have
     been duly given when delivered by hand, if delivered personally or by
     courier, or three days after being deposited in the mail (registered or
     certified mail, postage prepaid, return receipt requested) as follows: if
     to the Company, to it at 1411 East Mission Avenue, Spokane, Washington
     99202, and if to a holder, to the address of such holder set forth in the
     security register or other records of the Company, or to such other address
     as the Company or any such holder may have furnished to the other in
     writing in accordance herewith, except that notices of change of address
     shall be effective only upon receipt.

          (d) Parties in Interest. All the terms and provisions of this Exchange
     and Registration Rights Agreement shall be binding upon, shall inure to the
     benefit of and shall be enforceable by the parties hereto and the holders
     from time to time of the Registrable Securities and the respective
     successors and assigns of the parties hereto and such holders. In the event
     that any transferee of any holder of Registrable Securities shall acquire
     Registrable Securities, in any manner, whether by gift, bequest, purchase,
     operation of law or otherwise, such transferee shall, without any further
     writing or action of any kind, be deemed a beneficiary hereof for all
     purposes and such Registrable Securities shall be held subject to all of
     the terms of this Exchange and Registration Rights Agreement, and by taking
     and holding such Registrable Securities such transferee shall be entitled
     to receive the benefits of, and be conclusively deemed to have agreed to be
     bound by all of the applicable terms and provisions of this Exchange and
     Registration Rights Agreement. If the Company shall so request, any such
     successor, assign or transferee shall agree in writing to acquire and hold
     the Registrable Securities subject to all of the applicable terms hereof.

          (e) Survival. The respective indemnities, agreements, representations,
     warranties and each other provision set forth in this Exchange and
     Registration Rights Agreement or made pursuant hereto shall remain in full
     force and effect regardless of any investigation (or statement as to the
     results thereof) made by or on behalf of any holder of Registrable
     Securities, any director, officer or partner of such holder, any agent or
     underwriter or any director, officer or partner thereof, or any controlling
     person of any of the foregoing, and shall survive delivery of and payment
     for the Registrable Securities pursuant to the Purchase Agreement and the
     transfer and registration of Registrable Securities by such holder and the
     consummation of an Exchange Offer.

          (f) GOVERNING LAW. THIS EXCHANGE AND REGISTRATION RIGHTS AGREEMENT
     SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE
     OF NEW YORK.

          (g) Headings. The descriptive headings of the several Sections and
     paragraphs of this Exchange and Registration Rights Agreement are inserted
     for convenience only, do not constitute a part of this Exchange and
     Registration Rights Agreement and shall not affect in any way the meaning
     or interpretation of this Exchange and Registration Rights Agreement.

          (h) Entire Agreement; Amendments. This Exchange and Registration
     Rights Agreement and the other writings referred to herein (including the
     Indenture and the form of Securities) or delivered pursuant hereto which


                                       21



     form a part hereof contain the entire understanding of the parties with
     respect to its subject matter. This Exchange and Registration Rights
     Agreement supersedes all prior agreements and understandings between the
     parties with respect to its subject matter. This Exchange and Registration
     Rights Agreement may be amended and the observance of any term of this
     Exchange and Registration Rights Agreement may be waived (either generally
     or in a particular instance and either retroactively or prospectively) only
     by a written instrument duly executed by the Company and the holders of a
     majority in aggregate principal amount of the Registrable Securities at the
     time outstanding. Each holder of any Registrable Securities at the time or
     thereafter outstanding shall be bound by any amendment or waiver effected
     pursuant to this Section 9(h), whether or not any notice, writing or
     marking indicating such amendment or waiver appears on such Registrable
     Securities or is delivered to such holder.

          (i) Inspection. For so long as this Exchange and Registration Rights
     Agreement shall be in effect, this Exchange and Registration Rights
     Agreement and a complete list of the names and addresses of all the holders
     of Registrable Securities shall be made available for inspection and
     copying on any business day by any holder of Registrable Securities for

     of the holders of Registrable Securities under the Securities, the
     Indenture and this Agreement) at the offices of the Company at the address
     thereof set forth in Section 9(c) above and at the office of the Trustee
     under the Indenture.

          (j) Counterparts. This agreement may be executed by the parties in
     counterparts, each of which shall be deemed to be an original, but all such
     respective counterparts shall together constitute one and the same
     instrument.


                                       22



          If the foregoing is in accordance with your understanding, please sign
and return to us four counterparts hereof, and upon the acceptance hereof by
you, this letter and such acceptance hereof shall constitute a binding agreement
between you and the Company.

                        Notice of Registration Statement

                                     (Date)


Reference is hereby made to the Exchange and Registration Rights Agreement (the
"Exchange and Registration Rights Agreement") between Avista Corporation (the
"Company") and the Purchasers named therein. Pursuant to the Exchange and
Registration Rights Agreement, the Company has filed with the United States
Securities and Exchange Commission (the "Commission") a registration statement
on Form [__] (the "Shelf Registration Statement") for the registration and
resale under Rule 415 of the Securities Act of 1933, as amended (the "Securities
Act"), of the Company's _____% Notes due __________ (the "Securities"). A copy
of the Exchange and Registration Rights Agreement is attached hereto. All
capitalized terms not otherwise defined herein shall have the meanings ascribed
thereto in the Exchange and Registration Rights Agreement.

Each beneficial owner of Registrable Securities (as defined in the Exchange and
Registration Rights Agreement) is entitled to have the Registrable Securities
beneficially owned by it included in the Shelf Registration Statement. In order
to have Registrable Securities included in the Shelf Registration Statement,
this Notice of Registration Statement and Selling Securityholder Questionnaire
("Notice and Questionnaire") must be completed, executed and delivered to the
Company's counsel at the address set forth herein for receipt ON OR BEFORE

not be named as selling securityholders in the Shelf Registration Statement and
(ii) may not use the Prospectus forming a part thereof for resales of

Certain legal consequences arise from being named as a selling securityholder in
the Shelf Registration Statement and related Prospectus. Accordingly, holders
and beneficial owners of Registrable Securities are advised to consult their own
securities law counsel regarding the consequences of being named or not being
named as a selling securityholder in the Shelf Registration Statement and
related Prospectus.

          (3) only as follows (if at all): Such Registrable Securities may be
          sold from time to time directly by the undersigned Selling
          Securityholder or, alternatively, through underwriters, broker-dealers
          or agents. Such Registrable Securities may be sold in one or more
          transactions at fixed prices, at prevailing market prices at the time
          of sale, at varying prices determined at the time of sale, or at
          negotiated prices. Such sales may be effected in transactions (which

          engage in short sales of the Registrable Securities in the course of
          hedging the positions they assume. The Selling Securityholder may also
          sell Registrable Securities short and deliver Registrable Securities
          to close out such short positions, or loan or pledge Registrable
          Securities to broker-dealers that in turn may sell such securities.

          State any exceptions here:

     Delivery of this Letter of Transmittal to an address other than as
set-forth above, or transmission of this Letter of Transmittal via facsimile
other than as set forth above, will not constitute a valid delivery of this
Letter of Transmittal.





     The undersigned acknowledges that he or she has received and reviewed a
prospectus, dated        , 2001 (the "Prospectus"), of Avista Corporation, a
Washington corporation (the "Company"), and this letter of transmittal (the
"Letter of Transmittal"), which together constitute the Company's offer (the
"Exchange Offer") to issue an aggregate principal amount of up to $400,000,000
of its 9.75% Senior Notes due June 1, 2008 (the "New Notes"), which have been
registered under the Securities Act of 1933, as amended (the "Securities Act"),
in exchange for a like principal amount of issued and outstanding 9.75% Senior
Notes due June 1, 2008 (the "Old Notes" and, together with the New Notes, the
"Notes"), which were not so registered. Capitalized terms used but not defined
herein have the meanings given to them to the Prospectus.

     In order for any Holder of Old Notes to tender all or any portion of such
Old Notes, the Exchange Agent must receive either this Letter of Transmittal
completed by such Holder or an Agent's Message (as hereinafter defined) with
respect to such Holder. Certificates for Old Notes are to be forwarded herewith
or, if a tender of Old Notes is to be made by book-entry transfer, the tender
should be made by book-entry transfer to the account maintained by the Exchange
Agent at The Depository Trust Company ("DTC") pursuant to the procedures set
forth in the Prospectus under "The Exchange Offer-Procedures for
Tendering-Registered Holders and DTC Participants". Holders of Old Notes whose
certificates are not immediately available, or who are unable to deliver their
certificates or confirmation of the book-entry tender of their Old Notes into
the Exchange Agent's account at DTC (a "Book-Entry Confirmation") and all other
documents required by this Letter of Transmittal to the Exchange Agent on or
prior to the Expiration Date, must tender their Old Notes according to the
guaranteed delivery procedures set forth in "The Exchange Offer -Procedures for
Tendering - Registered Holders and DTC Participants" section of the Prospectus.
See Instruction 1. Delivery of documents to DTC does not constitute delivery to
the Exchange Agent.

     By causing Old Notes to be credited to the Exchange Agent's account at DTC
in accordance with DTC's procedures for transfer, including the transmission by
DTC of an Agent's Message to the Exchange Agent, the DTC participant will be
deemed to confirm, on behalf of itself and the beneficial owners of such Old
Notes, all provisions of this Letter of Transmittal applicable to it and such
beneficial owners as fully as if it had completed the information required
herein and executed and delivered this Letter of Transmittal to the Exchange
Agent. As used herein, the term "Agent's Message" means a message,
electronically transmitted by DTC to and received by the Exchange Agent, and
forming a part of the Book-Entry Confirmation, which states that DTC has
received an express acknowledgement from a Holder of Old Notes stating that such
Holder has received and agrees to be bound by, and makes each of the
representations and warranties contained in, this Letter of Transmittal and,
further, that such Holder agrees that the Company may enforce this Letter of
Transmittal against such Holder.

     The term "Holder", as used in this Letter of Transmittal, means any of (a)
person in whose name Old Notes are registered on the books of the Company, (b)
any other person who has obtained a properly completed bond power from the
registered holder, and (c) any DTC participant whose Old Notes are held of
record by DTC. Holders who wish to tender their Old Notes must complete this
Letter of Transmittal in its entirety or must cause an Agent's Message to be
transmitted.

     Any other beneficial owner whose Old Notes are registered in the name of a
broker or other nominee and who wishes to tender should contact such broker or
nominee promptly and instruct such broker or nominee to tender on behalf of the
beneficial owner. If the beneficial owner wishes to tender on its own behalf,
such beneficial owner must, prior to completing and executing this Letter of
Transmittal and delivering its Old Notes, either make appropriate arrangements
to register ownership of the Old Notes in such beneficial owner's name or obtain
a properly completed bond power from the registered Holder of the Old Notes. The
transfer of registered ownership may take considerable time.

Subject to, and effective upon, the acceptance for exchange of the Old Notes tendered hereby, the undersigned hereby sells, assigns and transfers to, or upon the order of, the Company all right, title and interest in and to such Old Notes as are being tendered hereby. The undersigned hereby irrevocably constitutes and appoints the Exchange Agent its agent and attorney-in-fact with full power of substitution, for purposes of delivering this Letter of Transmittal and the Old Notes to the Company. The Power of Attorney granted in this paragraph shall be deemed irrevocable from and after the Expiration Date and coupled with an interest. The undersigned hereby acknowledges its full understanding that the Exchange Agent also performs functions as agent of the Company. The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the Old Notes tendered hereby and that the Company will acquire good and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim when the same are accepted by the Company. The undersigned hereby further represents and warrants that any New Notes acquired in exchange for Old Notes tendered hereby will have been acquired in the ordinary course of business of the person receiving such New Notes, whether or not such person is the undersigned, that neither the holder of such Old Notes nor any such other person is engaged or intends to engage in, or has an arrangement or understanding with any person to participate in, the distribution (within the meaning of the Securities Act) of such New Notes and that neither the holder of such Old Notes nor any such other person is an "affiliate," as defined in Rule 405 under the Securities Act, of the Company. The undersigned also acknowledges that this Exchange Offer is being made by the Company in reliance on an interpretation by the staff of the Securities and Exchange Commission (the "SEC"), as set forth in no-action letters issued to third parties, that the New Notes issued in exchange for the Old Notes pursuant to the Exchange Offer may be offered for resale, resold and otherwise transferred by holders thereof (other than any such holder that is an "affiliate" of the Company within the meaning of Rule 405 under the Securities Act), without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such New Notes are acquired in the ordinary course of such holders' business and that such holders have no arrangement with any person to participate in the distribution (within the meaning of the Securities Act) of such New Notes. The undersigned represents that it is not engaged in, and does not intend to engage in, and has no arrangement or understanding with any person to participate in, a distribution (within the meaning of the Securities Act) of New Notes. If the undersigned is a broker-dealer that will receive New Notes for its own account in exchange for Old Notes that were acquired as a result of market-making activities or other trading activities, it acknowledges that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Notes; however, by so acknowledging and by delivering a prospectus, the undersigned will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. The undersigned acknowledges that in reliance on an interpretation by the staff of the SEC, a broker-dealer may fulfill its prospectus delivery requirements with respect to the New Notes (other than a resale of New Notes received in exchange for an unsold allotment of Old Notes purchased directly from the Company) with the Prospectus which constitutes part of this Exchange Offer. The undersigned will, upon request, execute and deliver any additional documents deemed by the Exchange Agent or the Company to be necessary or desirable to complete the sale, assignment and transfer of the Old Notes tendered hereby. All authority conferred or agreed to be conferred in this Letter of Transmittal and every obligation of the undersigned hereunder shall be binding upon the successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of the undersigned and shall not be 4 affected by, and shall survive, the death or incapacity of the undersigned.

DELIVERY OF THIS LETTER OF TRANSMITTAL AND OLD NOTES; GUARANTEED DELIVERY PROCEDURES. In order for any Holder of Old Notes to tender all or any portion of such Old Notes, the Exchange Agent must receive either this Letter of Transmittal completed by such Holder or an Agent's Message (as hereinafter defined) with respect to such Holder. Certificates for all physically tendered Old Notes, or Book-Entry Confirmation, as the case may be, as well as a properly completed and duly executed Letter of Transmittal (or facsimile hereof or Agent's Message in lieu thereof) and any other documents required by this Letter of Transmittal, must be received by the Exchange Agent at the address set forth herein prior to the Expiration Date, or the tendering holder must comply with the guaranteed delivery procedures set forth below. Old Notes tendered hereby must be in denominations of principal amount of $1,000 and any integral multiple thereof. Holders whose certificates for Old Notes are not immediately available or who cannot deliver their certificates and all other required documents to the Exchange Agent prior to the Expiration Date, or who cannot complete the procedure for book-entry tender on a timely basis, may tender their Old Notes pursuant to the guaranteed delivery procedures set forth in the Prospectus under "The Exchange Offer-Procedures of Tendering-Registered Holders and DTC Participants-Registered Holders." Pursuant to such procedures, (1) such tender must be made through an Eligible Institution, (2) prior to the Expiration Date, the Exchange Agent must receive from such Eligible Institution a properly completed and duly executed Notice of Guaranteed Delivery, substantially in the form provided by the Company (by facsimile transmission, mail or hand delivery), setting forth the name and address of the holder of Old Notes, the certificate numbers of such Old Notes (unless tender is to be made by book-entry transfer) and the principal amount of Old Notes tendered, stating that the tender is being made thereby and guaranteeing that within five New York Stock Exchange ("NYSE") trading days after the date of delivery of the Notice of Guaranteed Delivery, the certificates for all physically tendered Old Notes, or a Book-Entry Confirmation, together with a properly completed and duly executed Letter of Transmittal (or facsimile thereof or Agent's Message in lieu thereof), with any required signature guarantees and any other documents required by the Letter of Transmittal will be deposited by the Eligible Institution with the Exchange Agent, and (3) the certificates for all physically tendered Old Notes, in the proper form for transfer, or Book-Entry Confirmation, as the case may be, together with a properly completed and duly executed Letter of Transmittal (or facsimile thereof or Agent's Message in lieu thereof), with any required signature guarantees and all other documents required by this Letter of Transmittal, must be received by the Exchange Agent within five NYSE trading days after the date of execution of the Notice of Guaranteed Delivery. The method of delivery of Old Notes, this Letter of Transmittal and all other required documents to the Exchange Agent is at the election and risk of the Holder, but the delivery will be deemed made only when actually received by the Exchange Agent. Instead of delivery by mail, it is recommended that Holders use an overnight or hand delivery service. In all cases, sufficient time should be allowed to assure delivery to the Exchange Agent before the Expiration Date. No Old Notes or Letters of Transmittal should be sent to Avista Corp. Holders may request their respective brokers, dealers, commercial banks, trust companies or nominees to effect the above transactions for such Holders. See the Prospectus under "The Exchange Offer." 8 2. PARTIAL TENDERS (NOT APPLICABLE TO HOLDERS WHO TENDER BY BOOK-ENTRY TRANSFER). If less than all of the Old Notes evidenced by a submitted certificate are to be tendered, the tendering holder(s) should fill in the aggregate principal amount of Old Notes to be tendered in the box above entitled "Description of Old Notes -- Principal Amount Tendered." A reissued certificate representing the balance of nontendered Old Notes will be sent to such tendering holder, unless otherwise provided in the appropriate box on this letter, promptly after the Expiration Date. All of the Old Notes delivered to the Exchange Agent will be deemed to have been tendered unless otherwise indicated. 3. SIGNATURES ON THIS LETTER; BOND POWERS AND ENDORSEMENTS; GUARANTEE OF SIGNATURES. If this Letter of Transmittal is signed by the Holder of the Old Notes tendered hereby, the signature must correspond exactly with the name as written on the face of the certificates or on DTC's security position listing as the holder of such Old Notes without any change whatsoever. If any tendered Old Notes are owned of record by two or more joint owners, all of such owners must sign this Letter. If any tendered Old Notes are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate copies of this Letter of Transmittal as there are different registrations of certificates. If this Letter of Transmittal is signed by the registered holder or holders of the Old Notes specified herein and tendered hereby, no endorsements of certificates or separate bond powers are required. If, however, the New Notes are to be issued, or any untendered Old Notes are to be reissued, to a person other than the registered holder, then endorsements of any certificates transmitted hereby or separate bond powers are required. Signatures on such certificate(s) or bond powers must be guaranteed by an Eligible Institution. If this Letter of Transmittal is signed by a person other than the registered holder or holders of any certificate(s) specified herein, such certificate(s) must be endorsed or accompanied by appropriate bond powers, in either case signed exactly as the name or names of the registered holder or holders appear(s) on the certificate(s) and signatures on such certificate(s) or bond powers must be guaranteed by an Eligible Institution. If this Letter of Transmittal or any certificates representing Old Notes or any bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and, unless waived by the Company, proper evidence satisfactory to the Company of their authority to so act must be submitted. EXCEPT AS PROVIDED BELOW, ENDORSEMENTS ON CERTIFICATES FOR OLD NOTES OR SIGNATURES ON BOND POWERS REQUIRED BY THIS INSTRUCTION 3 MUST BE GUARANTEED BY A FIRM WHICH IS A MEMBER OF A REGISTERED NATIONAL SECURITIES EXCHANGE OR A MEMBER OF THE NATIONAL ASSOCIATION OF SECURITIES DEALERS, INC. OR BY A COMMERCIAL BANK OR TRUST COMPANY HAVING AN OFFICE OR CORRESPONDENT IN THE UNITED STATES (AN "ELIGIBLE INSTITUTION"). SIGNATURES ON THIS LETTER OF TRANSMITTAL NEED NOT BE GUARANTEED BY AN ELIGIBLE INSTITUTION IF THE OLD NOTES ARE TENDERED: (1) BY A REGISTERED HOLDER OF OLD NOTES WHO HAS NOT COMPLETED THE BOX ENTITLED "SPECIAL ISSUANCE INSTRUCTIONS" OR "SPECIAL DELIVERY INSTRUCTIONS" OR (2) FOR THE ACCOUNT OF AN ELIGIBLE INSTITUTION. 9 4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTION. Tendering Holders of Old Notes should indicate in the applicable box the name and address to which New Notes issued pursuant to the Exchange Offer and/or substitute certificates evidencing Old Notes not exchanged are to be issued or sent, if different from the name or address of the person signing this Letter of Transmittal. In the case of issuance in a different name, the employer identification or social security number of the person named must also be indicated. Holders tendering Old Notes by book-entry transfer may request that Old Notes not exchanged be credited to such account maintained at DTC as such Holder may designate hereon. If no such instructions are given, such Old Notes not exchanged will be returned to the name or address of the person signing this Letter. 5. TAX IDENTIFICATION NUMBER. Federal income tax law generally requires that a tendering holder whose Old Notes are accepted for exchange must provide the Company (as payor) with such holder's correct Taxpayer Identification Number ("TIN") on Substitute Form W-9 below, which in the case of a tendering holder who is an individual, is his or her social security number. If the Company is not provided with the current TIN or an adequate basis for an exemption, such tendering holder may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, delivery to such tendering holder of New Notes may be subject to backup withholding in an amount equal to 31% of all reportable payments made after the exchange. If withholding results in an overpayment for taxes, a refund may be obtained. Exempt holders of Old Notes (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. See the enclosed Guidelines of Certification of Taxpayer Identification Number on Substitute Form W-9 (the "W-9 Guidelines") for additional instructions. To prevent backup withholding, each tendering Holder of Old Notes must provide its correct TIN by completing the "Substitute Form W-9" set forth below, certifying that the Holder is a U.S. person (including a U.S. resident alien), that the TIN provided is correct (or that such Holder is awaiting a TIN) and that (1) the Holder is exempt from backup withholding, (2) the Holder has not been notified by the Internal Revenue Service that such Holder is subject to a backup withholding as a result of a failure to report all interest or dividends or (3) the Internal Revenue Service has notified the Holder that such Holder is no longer subject to backup withholding. If the tendering Holder of Old Notes is a nonresident alien or foreign entity not subject to backup withholding, such Holder must give the Company a completed Form W-8BEN, Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding, or if applicable, Form W-8ECI, Certificate of Foreign Person's Claim for Exemption From Withholding on Income Effectively Connected with the Conduct of a Trade or Business in the United States. These forms may be obtained from the Exchange Agent. If the Old Notes are in more than one name or are not in the name of the actual owner, such Holder should consult the W-9 Guidelines for information on which the TIN to report. If such Holder does not have a TIN, such Holder should consult the W-9 Guidelines for instructions on applying for a TIN, check the box in Part 2 of the Substitute Form W-9 and write "applied for" in lieu of its TIN. Note: Checking this box and writing "applied for" on the Form means that such Holder has already applied for a TIN or that such Holder intends to apply for one in the near future. If such Holder does not provide its TIN to the Company within 60 days, backup withholding will begin and continue until such Holder furnishes its TIN to the Company. 6. TRANSFER TAXES. The Company will pay all transfer taxes, if any, applicable to the transfer of Old Notes to it or its order pursuant to the Exchange Offer. If, however, New Notes and/or substitute Old Notes not exchanged are to be delivered to, or are 10 to be registered or issued in the name of, any person other than the registered holder of the Old Notes tendered hereby, or if tendered Old Notes are registered in the name of any person other than the person signing this Letter of Transmittal, or if a transfer tax is imposed for any reason other than the transfer of Old Notes to the Company or its order pursuant to the Exchange Offer, the amount of any such transfer taxes (whether imposed on the registered holder or any other person) will be payable by the tendering Holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted herewith, the amount of such transfer taxes will be billed directly to such tendering Holder. 7. COMPANY DETERMINATION FINAL; WAIVER OF CONDITIONS. All questions as to the validity, form eligibility (including time of receipt), acceptance of tendered Old Notes and withdrawal of tendered Old Notes will be determined by the Company in its sole discretion, which determination will be final and binding. The Company reserves the absolute right to reject any and all Old Notes not properly tendered or any Old Notes the Company's acceptance of which would, in the opinion of counsel for the Company, be unlawful. The Company also reserves the right to waive any irregularities or conditions of tender as to particular Old Notes. The Company's interpretation of the terms and conditions of the Exchange Offer (including the instructions in this Letter of Transmittal) shall be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of Old Notes must be cured within such time as the Company shall determine. Neither the Company, the Exchange Agent nor any other person shall be under any duty to give notification of defects or irregularities with respect to tenders of Old Notes, nor shall any of them incur any liability for failure to give such notification. Tenders of Old Notes will not be deemed to have been made until such defects or irregularities have been cured or waived. Any Old Notes received by the Exchange Agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned by the Exchange Agent to the tendering Holders of the Old Notes, unless otherwise provided in this Letter of Transmittal, as soon as practicable following the Expiration Date. 8. NO CONDITIONAL TENDERS. No alternative, conditional, irregular or contingent tenders will be accepted. All tendering Holders of Old Notes, by causing this Letter of Transmittal or an Agent's Message in lieu thereof to be delivered to the Exchange Agent, shall waive any right to receive notice of the acceptance of their Old Notes for exchange. Neither the Company, the Exchange Agent nor any other person is obligated to give notice of any defect or irregularity with respect to any tender of Old Notes nor shall any of them incur any liability for failure to give any such notice. 9. MUTILATED, LOST, STOLEN OR DESTROYED OLD NOTES. Any Holder whose Old Notes have been mutilated, lost, stolen or destroyed should contact the Exchange Agent at the addresses indicated above for further instructions. 10. REQUESTS FOR ADDITIONAL COPIES. Requests for additional copies of the Prospectus and this Letter of Transmittal, may be directed to the Exchange Agent, at the addresses and telephone numbers indicated above. 11

Certain penalties may also apply.

                                      II.

     We have also assumed the following, without making any inquiry into the
reasonableness or validity thereof:

     A.   The applicable provisions of the Securities Act, the Trust Indenture
          Act of 1939, as amended, and the securities or blue sky laws of
          various states shall have been complied with.

     B.   The Securities will be duly executed, authenticated and delivered
          prior to their issuance against consideration therefor as set forth in
          the Registration Statement and in accordance with the proceedings and
          actions of the Company's board of directors relating to the
          transactions contemplated by the Registration Statement.

     C.   There are no facts or circumstances specifically relating to any
          parties other than the Company (the "Other Parties") that might
          prevent the Other Parties from enforcing any of the rights to which
          our opinion relates.

                                      III.

     We express no opinion as to:

     (a)  The applicable choice of law rules that may affect the interpretation
          or enforcement of any of the Securities.

     (b)  Any securities, tax, anti-trust, land use, safety, environmental,
          hazardous materials, insurance company or banking laws, rules or
          regulations, or any laws, rules or regulations applicable to any of
          the Other Parties by virtue of their status as regulated entities, or
          whether governmental consents, approvals, authorizations,
          registrations, declarations or filings required in connection with
          exchange of the Securities will be applied for, received or made.

     (c)  The enforceability of any provision of the Securities that relates to
          the choice of arbitration as a dispute resolution mechanism.

     (d)  The effect on the obligations of the Company, and the Other Parties'
          rights, under the Securities of laws relating to fraudulent transfers
          and fraudulent obligations set forth in Sections 544 and 548 of the
          federal Bankruptcy Code or applicable state law.

     (e)  The enforceability of any waiver of immunities contained in the
          Securities.

     This opinion is limited to (i) the federal laws of the United States of
America, (ii) the laws of the State of Washington, and (iii) the statutes (and
regulations promulgated thereunder) of the States of California, Idaho, Montana
and Oregon pertaining to the regulation of public utilities in those States. We
disclaim any opinion as to the laws of any other jurisdiction. We further
disclaim any opinion as to any statute, rule, regulation, ordinance, order or
other promulgation of any regional or local governmental body or as to any
related judicial or administrative opinion.

                                      IV.

     Based upon the foregoing and our examination of such questions of law as we
have deemed necessary or appropriate for our opinion, and subject to the
limitations and qualifications expressed herein, it is our opinion that the
Securities, when issued and delivered as contemplated in the Registration
Statement, will be legally issued and will be binding obligations of the
Company, subject (i) to bankruptcy, insolvency, reorganization, arrangement,
moratorium and other laws of general applicability relating to or affecting
creditors' rights and (ii) to general principals of equity, whether such
enforceability is considered in a proceeding in equity or at law.

                                       V.

     We further advise you that:

     A.   As noted, the enforceability of the Securities is subject to the
          effect of general principles of equity. These principles include,
          without limitation, concepts of commercial reasonableness, materiality
          and good faith and fair dealing. As applied to the Securities, these
          principles will require the Other Parties to act reasonably, in good
          faith and in a manner that is not arbitrary or capricious in the
          administration and enforcement of the Securities and will preclude the
          Other Parties from invoking penalties for defaults that bear no
          reasonable relation to the damage suffered or that would otherwise
          work a forfeiture.

     B.   The enforceability of the Securities is subject to the effects of (i)
          Section 62A.1-102 of Revised Code of Washington (the "WA Code"), which
          provides that obligations of good faith, diligence, reasonableness and
          care prescribed by the WA Code may not be disclaimed by agreement,
          although the parties may by agreement determine the standards by which
          the performance of such obligations is to be measured if those
          standards are not manifestly unreasonable, (ii) Section 62A.1-203 of
          the WA Code, which imposes an obligation of good faith in the
          performance or enforcement of a contract and (iii) legal principles
          under which a court may refuse to enforce, or may limit the
          enforcement of, a contract or any clause of a contract that a court
          finds as a matter of law to have been unconscionable at the time it
          was made.

     C.   The effectiveness of indemnities, rights of contribution, exculpatory
          provisions and waivers of the benefits of statutory provisions may be
          limited on public policy grounds.

     D.   Pursuant to Section 4.84.330 of the WA Code, any provision in an
          agreement requiring a party to pay another party's attorneys' fees and
          costs in actions to enforce the provisions of such agreement will be
          construed to entitle the prevailing party in any action, whether or
          not that party is the specified party, to be awarded its reasonable
          attorneys' fees, costs and necessary disbursements.

     E.   Provisions of any agreement requiring that waivers must be in writing
          may not be binding or enforceable if a non-executory oral agreement
          has been created modifying any such provision or an implied agreement
          by trade practice or course of conduct has given rise to a waiver.

                                       VI.

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

                                      VII.

     The foregoing opinion is being delivered solely to you in connection with
the filing of the Registration Statement and is solely for your benefit and the
benefit of the holders of the Securities. This opinion may not be relied on by
you for any other purpose or by any other person for any purpose without our
written consent. We disclaim any obligation to advise you of any change of law
that occurs, or any facts of which we become aware, after the date of this
opinion.

Avista Corporation

Spokane, WA 99202


Ladies and Gentlemen:

          We are acting as counsel to Avista Corporation, a Washington
corporation (the "Company"), in connection with the filing by the Company of a
Registration Statement on Form S-4 (the "Registration Statement") under the
Securities Act of 1933, as amended (the "Act"), relating to the registration of
$400,000,000 in aggregate principal amount of 9.75% Senior Notes Due June 1,
2008 (the "New Notes") of the Company, in connection with an offer by the
Company to issue the New Notes in exchange for 9.75% Senior Notes due June 1,
2008 of the Company, which are currently outstanding in the same aggregate
principal amount, all as described in the Registration Statement.

          Subject to the qualifications hereinafter expressed, we are of the
opinion that the New Notes, when issued and delivered as contemplated in the
Registration Statement, will be legally issued and will be binding obligations
of the Company.

          We are further of the opinion that the information contained in the
Registration Statement under the caption "Certain U.S. Federal Income Tax
Considerations" constitutes an accurate description, in general terms, of the
indicated federal income tax consequences to holders of the New Notes of the
exchange offer contemplated in the Registration Statement.

          To the extent that the opinions relate to or are dependent upon
matters governed by the laws of other States, we have relied the opinion of
Heller Ehrman White & McAuliffe 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.

     (a)  Name and address of each examining or supervising authority to

     (b)  Whether it is authorized to exercise corporate trust powers.

          Yes.

ITEM 2.   AFFILIATIONS WITH THE OBLIGOR.

          If the obligor is an affiliate of the trustee, describe each such
affiliation.

          None.

ITEM 4.   TRUSTEESHIPS UNDER OTHER INDENTURES

     a)   Title of the securities outstanding under each such other indenture.

          $66,700,000 City of Forsyth, Montana, Pollution Control Revenue
Refunding Bonds (Avista Corporation Colstrip Project) Series 1999A issued under
Indenture dated as of September 1, 1999.

          $17,000,000 City of Forsyth, Montana, Pollution Control Revenue

Act arises as a result of the trusteeship under any such other indenture,
including a statement as to how the indenture securities will rank as compared
with the securities issued under such other indenture.

          The Trustee is not deemed to have a conflicting interest within the

equally.
