[S-3ASR] Portland General Electric Company SEC Filing

Rhea-AI Filing Summary

Form 144 filed for PACCAR Inc (PCAR) discloses a proposed sale of 5,000 common shares through broker Charles Schwab on or about 25 Jul 2025. The shares were recently acquired the same day via an employee stock-option exercise and will be sold on the NASDAQ.

The aggregate market value of the planned sale is $504,689, versus 524.96 million shares outstanding; the transaction therefore represents roughly 0.001% of shares outstanding. No other sales were reported in the past three months, and the filer attests to possessing no undisclosed material information. While insider sales can attract attention, the size and timing suggest routine portfolio management rather than a signal of changing fundamentals.

Positive

• None.

Negative

• Insider intends to sell shares, which can be perceived as a modest negative sentiment signal even though the volume is negligible.

Insights

Securities Analyst

TL;DR: Minor insider sale—5k PCAR shares worth ~0.001% OS; negligible impact on valuation.

The Form 144 flags an affiliate’s intent to liquidate 5,000 shares valued at roughly $505k. Relative to PACCAR’s 525 million shares, dilution and market-supply effects are immaterial. The recent option exercise suggests the seller is monetizing compensation rather than signaling concern. No pattern of continued selling is disclosed. Investors may treat this as neutral, but persistent insider selling trends—not evident here—would warrant closer monitoring.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

The information in this prospectus and the other public filings incorporated by reference herein include statements that are forward-looking within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements include, but are not limited to, statements that relate to expectations, beliefs, plans, assumptions, and objectives concerning future results of operations, business prospects, loads, outcome of litigation and regulatory proceedings, capital expenditures, market conditions, events or performance, and other matters. Words or phrases such as “anticipates,” “believes,” “estimates,” “expects,” “intends,” “plans,” “predicts,” “projects,” “will likely result,” “will continue,” “should,” “based on,” “conditioned upon,” “considers,” “could,” “expected,” “forecast,” “goals,” “needs,” “promises,” “subject to,” “targets,” or similar expressions are intended to identify such forward-looking statements.

Forward-looking statements are not guarantees of future performance and involve risks and uncertainties, including those risks discussed in this prospectus or otherwise incorporated by reference, that could cause actual results or outcomes to differ materially from those expressed. PGE’s expectations, beliefs, and projections are expressed in good faith and are believed by the Company to have a reasonable basis including, but not limited to, management’s examination of historical operating trends and data contained either in internal records or available from third parties, but there can be no assurance that PGE’s expectations, beliefs, or projections will be achieved or accomplished.

In addition to any assumptions and other factors and matters discussed elsewhere in this prospectus or incorporated by reference herein, some important factors that could cause actual results or outcomes for PGE to differ materially from those discussed in such forward-looking statements include:

• governmental policies, executive orders, legislative action, and regulatory audits, investigations, and actions, including those of the Federal Energy Regulatory Commission (FERC), the Public Utility Commission of Oregon (OPUC), the United States Securities and Exchange Commission (SEC), and the Division of Enforcement of the Commodity Futures Trading Commission, with respect to allowed rates of return, financings, electricity pricing and price structures, acquisition and disposal of facilities and other assets, construction and operation of plant facilities, transmission of electricity, recovery of power costs, operating expenses, deferrals, timely recovery of costs and capital investments, energy trading activities, and current or prospective wholesale and retail competition;

• economic conditions that result in decreased demand for electricity, reduced revenue from sales of excess energy during periods of low wholesale market prices, impaired financial stability of vendors and service providers, and elevated levels of uncollectible customer accounts;

• trade tariffs, inflation, and volatility in interest rates;

• the impacts of changes in the tax code, including tax rates, minimum tax rates, adjustments made to deferred tax assets and liabilities, and changes impacting the availability of and ability to transfer renewable tax credits;

• risks and uncertainties related to current or future All-Source RFP projects, including, but not limited to regulatory processes, transmission capabilities, system interconnections, inflationary impacts, supply chain constraints, supply cost increases (including application of trade tariffs), permitting and construction delays, available tax credits, counterparty credit risk, and legislative uncertainty;

• changing customer expectations and choices that may reduce customer demand for PGE’s services may impact the Company’s ability to make and recover its investments through prices and earn its authorized return on equity, including the impact of growing distributed and renewable generation resources, changing customer demand for enhanced electric services, and an increasing risk that customers procure electricity from Electricity Service Suppliers (ESSs) or the adoption of community choice aggregation;

• the timing or outcome of legal and regulatory proceedings and issues including, but not limited to, the matters described in Regulatory Matters of the “Overview” in Item 2, along with “Regulatory Assets and Liabilities” in Note 3, Balance Sheet Components and Note 8, Contingencies in the Notes to the Condensed Consolidated Financial Statements in Item 1.—“Financial Statements” of our Quarterly Report on Form 10-Q for the quarter ended June 30, 2025;

• natural or human-caused disasters and other risks, including, but not limited to, earthquake, flood, ice, drought, extreme heat, lightning, wind, fire, accidents, equipment failure, acts of terrorism, computer system outages, and other events that disrupt PGE operations, damage PGE facilities and systems, cause the release of harmful materials, cause fires, and subject the Company to liability;

• unseasonable or severe weather and other natural phenomena, such as the greater size and prevalence of wildfires in Oregon in recent years, which could affect public safety, customers’ demand for power, and PGE’s financial health and ability and cost to procure adequate power and fuel supplies to serve its customers, access the wholesale energy market, or operate its generating facilities and transmission and distribution systems, and the Company’s costs to maintain, repair, and replace such facilities and systems, and recovery of such costs;

• ignitions caused by PGE assets or PGE’s ability to effectively implement a public safety power shut off and de-energize its system in the event of heightened wildfire risk or implement effective system hardening programs, the inability of which could lead to potential liability if energized systems were involved in wildfires that cause harm, as well as the risk that damages from wildfires may not be recoverable through prices or insurance, resulting in impact to the financial condition or reputation of the Company;

• operational factors affecting PGE’s power generating and battery storage facilities, including forced outages, fires, unscheduled delays, environmental impacts, hydro and wind conditions, and disruption of fuel supply, any of which may cause the Company to incur repair costs or purchase replacement power at increased costs;

• default or nonperformance on the part of any parties from whom PGE purchases fuel, capacity, or energy, which may cause the Company to incur costs to purchase replacement power and related renewable attributes at increased costs;

• complications arising from PGE’s jointly-owned plant, including changes in ownership, adverse regulatory outcomes or legislative actions, or operational failures that result in legal or environmental liabilities or unanticipated costs related to replacement power, repair costs, or abandoned costs;

• delays in the supply chain and increased supply costs, failure to complete capital projects on schedule or within budget, failure to obtain permits, inability to complete negotiations on contracts for capital projects, failure of counterparties to perform under agreements, or the abandonment of capital projects, any of which could result in the Company’s inability to recover project costs, or impact PGE’s competitive position, market share, or results of operations in a material way;

• volatility in wholesale power and natural gas prices, including but not limited to volatility caused by macroeconomic and international issues, that could require PGE to post additional collateral or issue additional letters of credit pursuant to power and natural gas purchase agreements;

• changes in the availability and price of wholesale power and fuels, including natural gas and coal, and the impact of such changes, including the potential impact of trade tariffs, on the Company’s power costs;

• capital market conditions, including availability of capital, volatility of interest rates, reductions in demand for investment-grade commercial paper, volatility of equity markets as well as changes in PGE’s credit ratings, any of which could have an impact on the Company’s cost of capital and its ability to access the capital markets to support requirements for working capital, construction of capital projects, the repayments of maturing debt, and stock-based compensation plans, which are relied upon in part to retain key executives and employees;

• future laws, regulations, and proceedings that could increase the Company’s costs of operating its thermal generating plants, or affect the operations of such plants by imposing requirements for additional emissions controls or significant emissions fees or taxes, particularly with respect to coal-fired generating facilities, in order to mitigate carbon dioxide, mercury, and other gas emissions;

• changes in, compliance with, and general uncertainty around environmental laws and policies;

TABLE OF CONTENTS

• the effects of climate change, whether global or local in nature, including unseasonable or extreme weather and other natural phenomena that may affect energy costs or consumption, increase the Company’s costs, cause damage to PGE facilities and system, or adversely affect its operations;

• the effectiveness of PGE’s risk management policies and procedures;

• cybersecurity attacks, data security breaches, physical attacks and security breaches, or other malicious acts, internally or to third parties, that cause damage to the Company’s generation, transmission, or distribution facilities, information technology systems, inhibit the capability of equipment or systems to function as designed or expected, or result in the release of confidential customer, vendor, employee, or Company information;

• reputational damage from negative publicity, protests, fines, penalties and other negative consequences resulting in regulatory and/or legal actions;

• physical attacks upon Company employees;

• employee workforce factors, including potential strikes, work stoppages, transitions in senior management, the ability to recruit and retain key employees and other talent, and turnover due to macroeconomic trends such as voluntary resignation of large numbers of employees similar to that experienced by other employers and industries during the COVID-19 pandemic;

• new federal, state, and local laws that could have adverse effects on operating results;

• failure to achieve the Company’s greenhouse gas (GHG) emission goals or being perceived to have either failed to act responsibly with respect to the environment or effectively respond to legislative requirements concerning GHG emission reductions, any of which could lead to adverse publicity and have adverse effects on the Company’s operations and/or damage the Company’s reputation;

• social attitudes regarding the electric utility and power industries;

• political and economic conditions;

• the impact of widespread health developments, and responses to such developments (such as voluntary and mandatory quarantines, including government stay at home orders, as well as shut downs and other restrictions on travel, commercial, social, and other activities), which could materially and adversely affect, among other things, demand for electric services, customers’ ability to pay, supply chains, personnel, contract counterparties, liquidity, and financial markets;

• changes in financial or regulatory accounting principles or policies imposed by governing bodies; and

• acts of war, terrorism, or civil disruption.

While we believe that the assumptions underlying such forward–looking statements are reasonable, there can be no assurance that future events or developments will not cause such statements to be inaccurate. Any forward-looking statement speaks only as of the date on which such statement is made and, except as required by law, PGE undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time and it is not possible for management to predict all such factors or assess the impact of any such factor on the business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. All forward-looking statements contained in this prospectus and the documents we incorporate by reference in this prospectus are qualified in their entirety by this cautionary statement. We expressly disclaim any obligation or undertaking to update or revise any forward-looking statements to reflect any changes in events or circumstances or in our expectations or results.

You should refer to our Articles of Incorporation and our Bylaws and to Oregon corporate law for a complete understanding of the terms and rights of our common stock.

General

Our Articles of Incorporation provide that we have authority to issue up to 160,000,000 shares of common stock, no par value. Our common stock is listed and traded on the New York Stock Exchange under the ticker symbol “POR.” The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company.

Except as otherwise provided by law or our Articles of Incorporation, and subject to the rights of holders of any outstanding shares of our preferred stock, all of the voting power of our shareholders is vested in the holders of our common stock, and each holder of common stock has one vote for each share on all matters voted upon by our shareholders. Our Articles of Incorporation do not provide for cumulative voting for the election of directors.

Dividend Rights

Except as otherwise provided by law, regulatory restriction or the Articles of Incorporation, and subject to the rights of holders of any outstanding shares of our preferred stock, holders of our common stock are entitled to receive dividends when and as declared by the Board of Directors out of any funds legally available for the payment of dividends.

Other Rights

Holders of our common stock do not have any preemptive or other rights to subscribe for, purchase or receive any proportionate or other amount of our common stock or any securities of the Company convertible into our common stock upon the issuance of our common stock or any such convertible securities. There are also no redemption or sinking fund provisions applicable to our common stock.

Liquidation Rights

If we were voluntarily or involuntarily liquidated, dissolved or wound up, the holders of our outstanding shares of common stock would be entitled to share in the distribution of all assets remaining after payment of all of our liabilities and after satisfaction of prior distribution rights and payment of any distributions owing to holders of any outstanding shares of our preferred stock.

Liability for Calls and Assessments

Directors are elected annually by a majority of votes cast by the shares entitled to vote in an election at a meeting at which a quorum is present, except in the case of a contested election. In the case of a contested election, directors are elected by a plurality of votes cast by the shares entitled to vote in an election at a meeting at which a quorum is present. Special meetings of our shareholders may be called by our Chairman of the Board, our Chief Executive Officer, our President or by our Board of Directors.

Except as otherwise provided by law or in our Articles of Incorporation, and subject to restrictions on the taking of shareholder action without a meeting under applicable law or the rules of a national securities association or

9

TABLE OF CONTENTS

exchange, action required or permitted by law to be taken at a shareholders’ meeting may be taken without a meeting if the action is taken by shareholders having not less than the minimum number of votes that would be required to take such action at a meeting at which all shareholders entitled to vote on the action were present and voted.

Vacancies and Removal of Directors

Any vacancy, including a vacancy resulting from an increase in the number of directors, occurring on our Board of Directors may be filled by our shareholders, the Board of Directors or the affirmative vote of a majority of the remaining directors if less than a quorum of the Board of Directors or by a sole remaining director. A vacancy that will occur at a specific later date, by reason of a resignation or otherwise, may be filled before the vacancy occurs, and the new director shall take office when the vacancy occurs.

Shareholders may remove one or more directors with or without cause at a meeting called expressly for that purpose. A director may be removed only if the number of votes cast to remove a director exceeds the number cast not to remove the director. If a director is elected by a voting group of shareholders, only those shareholders may participate in the vote to remove the director.

Provisions with Possible Anti-Takeover Effects

An Oregon company may provide in its articles of incorporation or bylaws that certain control share and business combination provisions in the Oregon Business Corporation Act do not apply to its shares. We have not opted out of these provisions.

Oregon Control Share Act. We are subject to Sections 60.801 through 60.816 of the Oregon Business Corporation Act, known as the “Oregon Control Share Act.” The Oregon Control Share Act generally provides that a person who acquires voting stock of an Oregon corporation, in a transaction that results in the acquiror holding more than 20%, 33 ¹/3% or 50% of the total voting power of the corporation, cannot vote the shares it acquires in the acquisition. An acquiror is broadly defined to include companies or persons acting as a group to acquire the shares of the Oregon corporation. This restriction does not apply if voting rights are given to the control shares by:

• a majority of the outstanding voting shares, including shares held by the company’s officers and employee directors; and

• a majority of the outstanding voting shares, excluding the control shares held by the acquiror and shares held by the company’s officers and employee directors.

In order to retain the voting rights attached to acquired shares, this vote would be required when an acquiror’s holdings exceed 20% of the total voting power, and again at the time the acquiror’s holdings exceed 33 ¹/3% and 50%, respectively.

The acquiror may, but is not required to, submit to the target company an “acquiring person statement” that includes specific information about the acquiror and its plans for the company. The acquiring person statement may also request that the company call a special meeting of shareholders to determine whether the control shares will be allowed to have voting rights. If the acquiror requests a special meeting and undertakes to pay the target company’s expenses of the meeting, the directors of the target company must, within 10 days after receiving the acquiring person statement, call a special meeting for the purpose of considering the voting rights of the control shares. If the acquiror does not request a special meeting of shareholders, the issue of voting rights of control shares will be considered at the next annual or special meeting of shareholders that is held more than 60 days after the date of the acquisition of control shares. If the acquiror’s control shares are allowed to have voting rights and represent a majority or more of all voting power, shareholders who do not vote in favor of voting rights for the control shares will have the right to receive the appraised fair value of their shares, which may not be less than the highest price paid per share by the acquiror for the control shares.

Shares are not deemed to be acquired in a control share acquisition if, among other things, they are acquired from the issuing corporation, or are issued pursuant to a plan of merger or exchange effected in compliance with the Oregon Business Corporation Act and the issuing corporation is a party to the merger or exchange agreement.

Oregon Business Combination Act. We are also subject to Sections 60.825 through 60.845 of the Oregon Business Corporation Act, known as the “Oregon Business Combination Act.” The Oregon Business

10

TABLE OF CONTENTS

Combination Act governs business combinations between Oregon corporations and a person or entity that acquires 15% or more of the outstanding voting stock of the corporation, thereby becoming an “interested shareholder.” The Oregon Business Combination Act generally provides that the corporation and the interested shareholder, or any affiliated entity of the interested shareholder, may not engage in business combination transactions for three years following the date the person acquired the shares. Business combination transactions for this purpose include:

• a merger or plan of exchange;

• any sale, lease, mortgage or other disposition of the assets of the corporation where the assets have an aggregate market value equal to 10% or more of the aggregate market value of the corporation’s assets or outstanding capital stock; and

• transactions that result in the issuance or transfer of capital stock of the corporation to the interested shareholder.

These business combination restrictions do not apply if:

• the board of directors approves the business combination or the transaction that resulted in the shareholder acquiring the shares before the acquiring shareholder acquires 15% or more of the corporation’s voting stock;

• as a result of the transaction in which the person acquired the shares, the acquiring shareholder became an interested shareholder and owner of at least 85% of the outstanding voting stock of the corporation, disregarding shares owned by employee directors and shares owned by certain employee benefits plans; or

• the board of directors and the holders of at least two-thirds of the outstanding voting stock of the corporation at an annual or special meeting of shareholders, disregarding shares owned by the interested shareholder, approve the business combination after the acquiring shareholder acquires 15% or more of the corporation’s voting stock.

A form of the indenture is attached as an exhibit to the registration statement of which this prospectus forms a part. The terms of the debt securities will include those set forth in the indenture and those made a part of the indenture by the Trust Indenture Act of 1939 (“TIA”). You should read the summary below, any accompanying prospectus supplement and the provisions of the indenture in their entirety before investing in our debt securities.

The aggregate principal amount of debt securities that may be issued under the indenture is unlimited. The prospectus supplement relating to any series of debt securities that we may offer will contain the specific terms of the debt securities. These terms may include, among others, the following:

• the title and aggregate principal amount of the debt securities and any limit on the aggregate principal amount of such series;

• any applicable subordination provisions for any subordinated debt securities;

• the maturity date(s) or method for determining same;

• the interest rate(s) or the method for determining same;

• the dates on which interest will accrue or the method for determining dates on which interest will accrue and dates on which interest will be payable and whether interest will be payable in cash, additional securities or some combination thereof;

• whether the debt securities are convertible or exchangeable into other securities and any related terms and conditions;

• redemption or early repayment provisions;

• authorized denominations;

• if other than the principal amount, the principal amount of debt securities payable upon acceleration;

• place(s) where payment of principal and interest may be made, where debt securities may be presented and where notices or demands upon the Company may be made;

• the form or forms of the debt securities of the series including such legends as may be required by applicable law;

• whether the debt securities will be issued in whole or in part in the form of one or more global securities and the date as of which the securities are dated if other than the date of original issuance;

TABLE OF CONTENTS

• the time period within which, the manner in which and the terms and conditions upon which we or the holders of the debt securities can select the payment currency;

• our obligation or right to redeem, purchase or repay debt securities under a sinking fund, amortization or analogous provision;

• any restriction or conditions on the transferability of the debt securities;

• provisions granting special rights to holders of the debt securities upon occurrence of specified events;

• additions or changes relating to compensation or reimbursement of the trustee of the series of debt securities;

General

We may sell the debt securities, including original issue discount securities, at par or at a substantial discount below their stated principal amount. Unless we inform you otherwise in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series or any other series outstanding at the time of issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of securities under the indenture.

We will describe in an accompanying prospectus supplement any other special considerations for any debt securities we sell that are denominated in a currency or currency unit other than U.S. dollars. In addition, debt securities may be issued where the amount of principal and/or interest payable is determined by reference to one or more currency exchange rates, commodity prices, equity indices or other factors. Holders of such securities may receive a principal amount or a payment of interest that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value of the applicable currencies, commodities, equity indices or other factors. Information as to the methods for determining the amount of principal or interest, if any, payable on any date, and the currencies, commodities, equity indices or other factors to which the amount payable on such date is linked will be described in an accompanying prospectus supplement.

United States federal income tax consequences and special considerations, if any, applicable to any such series will be described in an accompanying prospectus supplement.

We expect most debt securities to be issued in fully registered form in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. Subject to the limitations provided in the indenture and in an accompanying prospectus supplement, debt securities that are issued in registered form may be transferred or exchanged at the designated corporate trust office of the trustee, without the payment of any service charge, other than any tax or other governmental charge payable in connection therewith.

Global Securities

Unless we inform you otherwise in an accompanying prospectus supplement, the debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in an accompanying prospectus supplement. Unless and until a global security is exchanged in whole or in part for the individual debt securities, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor.

Governing Law

The indenture and the debt securities shall be construed in accordance with and governed by the laws of the State of New York, except to the extent the Trust Indenture Act of 1939 otherwise applies.

DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

We may issue stock purchase contracts, including contracts obligating holders to purchase from us, and obligating us to sell to the holders, a specified number of shares of our common stock or our debt securities at a future date or dates, which we refer to in this prospectus as stock purchase contracts. The price of the securities and the number of securities may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts, and may be subject to adjustment under anti-dilution formulas. The stock purchase contracts may be issued separately or as part of units consisting of a stock purchase contract and our debt securities or preferred securities or debt obligations of third parties, including U.S. treasury securities, or any combination of the foregoing, securing the holders’ obligations to purchase the securities under the stock purchase contracts, which we refer to herein as stock purchase units. The stock purchase contracts may require holders to secure their obligations under the stock purchase contracts in a specified manner. The stock purchase contracts also may require us to make periodic payments to the holders of the stock purchase contracts or the stock purchase units, as the case may be, or vice versa, and those payments may be unsecured or pre-funded in whole or in part.

The description in an accompanying prospectus supplement of any stock purchase contract or stock purchase unit we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable stock purchase contract or stock purchase unit, which will be filed with the SEC if we offer stock purchase contracts or stock purchase units. For more information on how you can obtain copies of any purchase contract or purchase unit we may offer, see “Where You Can Find More Information.” We urge you to read the applicable purchase contract or applicable purchase unit and any accompanying prospectus supplement in their entirety.

DESCRIPTION OF FIRST MORTGAGE BONDS

We may issue the first mortgage bonds under our Indenture of Mortgage and Deed of Trust dated July 1, 1945, between us and Computershare Trust Company, National Association (as successor to Wells Fargo Bank, National Association) as trustee (the “Trustee”), as supplemented and amended. The original mortgage, as so supplemented and amended, is referred to as the “Mortgage.” The first mortgage bonds that we may issue under the Mortgage are referred to as the “bonds.”

The following summary of material provisions of the Mortgage is not complete and may not contain all of the information that is important to you. This summary is subject to, and is qualified in its entirety by reference to, all of the provisions of the Mortgage, including the defined terms contained therein. We have filed the original mortgage and certain of the supplemental indentures amending the mortgage as exhibits to the registration statement of which this prospectus is a part. In addition, prior to issuing bonds, we will file a form of supplemental indenture describing the terms of the new bonds in a post-effective amendment to the registration statement. You should read the Mortgage and any applicable form of new supplemental indenture because those documents, and not this description, will define your rights as a holder of the bonds. The Mortgage has been qualified under the Trust Indenture Act of 1939, and you should also refer to the Trust Indenture Act of 1939 for provisions that apply to the bonds.

Secured Obligations

The bonds, when issued, will be our senior secured obligations and will be secured equally and ratably with all of our other first mortgage bonds now outstanding or hereafter issued under the Mortgage, by a first lien on substantially all of our now owned or hereafter acquired tangible utility property (except cash, securities, accounts receivable, motor vehicles, materials and supplies, fuel, certain minerals and mineral rights, property located outside of the states of Oregon, Washington, California, Arizona, New Mexico, Idaho, Montana, Wyoming, Utah, Nevada and Alaska, and certain other property specified in the Mortgage), subject, however, to certain permitted encumbrances and various exceptions, reservations, limitations, and minor irregularities and deficiencies in title which will not interfere with the proper operation and development of the mortgaged property. We refer to this collateral security as “bondable public utility property.”

The term “permitted encumbrances” means as of any particular time any of the following:

• liens for taxes, assessments, or governmental charges for the then current year and taxes, assessments, or governmental charges not then delinquent; and liens for taxes, assessments, or governmental charges already delinquent, but whose validity is being contested at the time by us in good faith by appropriate proceedings;

• liens and charges incidental to construction or current operation which have not at such time been filed or asserted or the payment of which has been adequately secured or which, in the opinion of counsel, are insignificant in amount;

• liens, securing obligations neither assumed by us nor on account of which we customarily pay interest directly or indirectly, existing, either at July 1, 1945, or as to property thereafter acquired, at the time of acquisition by us, upon real estate or rights in or relating to real estate acquired by us for substation, measuring station, regulating station, or transmission, distribution, or other right-of-way purposes;

• any right which any municipal or governmental body or agency may have by virtue of any franchise, license, contract, or statute to purchase, or designate a purchaser of, or order the sale of, any of our property upon payment of reasonable compensation therefor or to terminate any franchise, license, or other rights or to regulate our property and business;

• the lien of judgments covered by insurance or if not so covered, not exceeding at any one time $100,000 in aggregate amount;

• easements or reservations in respect of any of our property for the purpose of rights-of-way and similar purposes, reservations, restrictions, covenants, party wall agreements, conditions of record, and other encumbrances (other than to secure the payment of money) and minor irregularities or deficiencies in the record evidence of title, which in the opinion of counsel (at the time of the acquisition of the property affected or subsequently) will not interfere with the proper operation and development of the property affected thereby;

15

TABLE OF CONTENTS

• any lien or encumbrance, moneys sufficient for the discharge of which have been deposited in trust with the Trustee or with the trustee or mortgagee under the instrument evidencing such lien or encumbrance, with irrevocable authority to the Trustee or to such other trustee or mortgagee to apply such moneys to the discharge of such lien or encumbrance to the extent required for such purposes; and

• the lien reserved for rent and for compliance with the terms of the lease in the case of leasehold estates.

The Mortgage permits the acquisition of property subject to prior liens. However, no property subject to prior liens (other than purchase money liens) may be acquired (i) if at the date the property is acquired, the principal amount of indebtedness secured by prior liens, together with all of our other prior lien indebtedness, is greater than 10% of the aggregate principal amount of debt securities outstanding under the Mortgage, (ii) if at the date the property is acquired, the principal amount of indebtedness secured by prior liens is greater than 60% of the cost of such property to us, or (iii) in certain cases if the property had been used by another entity in a business similar to ours, unless the net earnings of such property meet certain tests.

We have covenanted, among other things,

• to not issue debt securities under the Mortgage in any manner other than in accordance with the Mortgage;

• except as permitted by the Mortgage, to keep the Mortgage a first priority lien on the property subject to it;

• except as permitted by the Mortgage, to not suffer any act or thing whereby all of the properties subject to it might or could be impaired; and

• in the event that we are no longer required to file reports with the SEC, and so long as the bonds are outstanding, to furnish to the Trustee the financial and other information that would be required to be contained in the reports filed with the SEC on Forms 10-Q, 10-K, and 8-K if we were required to file such reports.

Redemption and Purchase of Bonds

A prospectus supplement will disclose any provisions for the redemption or purchase of any particular series of bonds. Cash deposited under any provision of the Mortgage (with certain exceptions) may be applied to the purchase of the bonds.

Sinking Fund Provisions

We may establish a sinking fund for the benefit of a particular series of bonds. If a sinking fund is established, we will be required to deposit with the Trustee at certain specified times sufficient cash to redeem a percentage of the series or the whole series. The prospectus supplement with respect to that series will state the price or prices at which, and the terms and conditions upon which, the bonds will be redeemed. The prospectus supplement will also set forth the percentage of securities of the series to be redeemed.

Replacement Fund

If the amount of the minimum provision for depreciation upon bondable public utility property (as defined above) exceeds the balance of property additions credits available in any year, we will pay the excess to the Trustee on May 1 of the following year by either payments in cash or by delivery of first mortgage bonds. The balance of property additions available for credit is the net of the aggregate property additions acquired or constructed by us from March 31, 1945, to the end of the calendar year for which the payment is due, less property additions that (i) have been previously made the basis for action or credit under the Mortgage or (ii) have been used as a credit on all previous replacement fund certificates. We may, at our election, credit against any deficiency in the replacement fund amount (i) available retirements of first mortgage bonds, (ii) certain expenditures on bondable public utility property subject to prior lien, and (iii) certain retirements of prior lien indebtedness. If those credits at any time exceed the replacement fund requirement, we may withdraw cash or first mortgage bonds held by the Trustee in the replacement fund. We may also reinstate available retirements of first mortgage bonds that we previously took as credit against any replacement fund requirement.

16

TABLE OF CONTENTS

Cash deposited in the replacement fund may, at our option, be applied to the redemption or purchase of bonds or, in certain circumstances, to the redemption or purchase of other first mortgage bonds. The redemptions of the bonds would be at the then applicable regular redemption prices.

Minimum Provision for Depreciation

Under the Mortgage, there is a “minimum provision for depreciation” of bondable public utility property. The aggregate amount of the minimum provision for depreciation of bondable public utility property for any period after March 31, 1945, is $35,023,487.50 plus an amount for each calendar year or fraction of a year after December 31, 1966, equal to the greater of (i) 2% of depreciable bondable public utility property, as shown by our books as of January 1 of that year, as to which we were required to make appropriations to a reserve for depreciation or obsolescence or (ii) the amount we actually appropriated in respect of the depreciable bondable public utility property to a reserve for depreciation or obsolescence, in either case less an amount equal to the aggregate of (a) the amount of any property additions which we made as the basis for a sinking fund credit during the calendar year, and (b) 166 2/3% of the principal amount of any first mortgage bonds of any series which we credited against any sinking fund payment or which we redeemed in anticipation of, or out of moneys paid to the Trustee on account of, any sinking fund payment due during the calendar year. The property additions and first mortgage bonds referred to in (a) and (b) above become disqualified from being made the basis of the authentication and delivery of first mortgage bonds or any other further action or credit under the Mortgage. In addition, the minimum provision for depreciation shall also include (1) the amount of any property additions referred to in (a) above which after December 31, 1966, were made the basis for a sinking fund credit pursuant to the provisions of a sinking fund for first mortgage bonds of any series, and thereafter became “available additions” as a result of the fact that all first mortgage bonds of such series ceased to be outstanding, and (2) 166 2/3% of the principal amount of first mortgage bonds referred to in (b) above, which after December 31, 1966, were credited against any sinking fund payment, or were redeemed in anticipation of, or out of moneys paid to the Trustee on account of, any sinking fund payment for first mortgage bonds of any series, and thereafter became available retirements of first mortgage bonds as a result of the fact that all first mortgage bonds of such series ceased to be outstanding.

Issuance of Additional Bonds

Subject to the issuance restrictions described below, we may issue an unlimited amount of first mortgage bonds under the Mortgage. First mortgage bonds may be issued from time to time on the basis of, and in an aggregate principal amount not exceeding, the following: (i) 60% of the amount of available additions; (ii) an amount of cash deposited with the Trustee; and/or (iii) the aggregate principal amount of available retirements of first mortgage bonds.

With certain exceptions in the case of (iii) above, the issuance of first mortgage bonds is subject to the amount of net earnings available for interest for 12 consecutive months within the preceding 15 months being at least twice the annual interest requirements on all first mortgage bonds to be outstanding and all prior lien indebtedness. Cash deposited with the Trustee pursuant to (ii) above may be (a) withdrawn in an amount equal to 60% of available additions, (b) withdrawn in an amount equal to the aggregate principal amount of available retirements of first mortgage bonds, or (c) applied to the purchase or redemption of first mortgage bonds.

Available additions are determined, at any time, by deducting from the aggregate amount of property additions since March 31, 1945, (i) the greater of the aggregate amount of retirements of bondable public utility property not subject to a prior lien, or the aggregate amount of the minimum provision for depreciation upon bondable public utility property not subject to a prior lien since March 31, 1945, and (ii) the aggregate amount of available additions theretofore made the basis for action or credit under the Mortgage. Property additions taken as a credit against the replacement fund requirement are not deemed to be “made the basis for action or credit.”

Dividend Restrictions

So long as any of the bonds, or any of the first mortgage bonds authenticated under the Mortgage are outstanding, we will be subject to the following restrictions:

• we may not pay or declare dividends (other than stock dividends) or other distributions on our common stock, and

• we may not purchase any shares of our capital stock (other than in exchange for or from the proceeds of other shares of our capital stock),

17

TABLE OF CONTENTS

in either case if the aggregate amount distributed or expended after December 31, 1944, would exceed the aggregate amount of our net income, as adjusted, available for dividends on our common stock accumulated after December 31, 1944.

Release and Substitution of Property

Property subject to the lien of the Mortgage may (subject to certain exceptions and limitations) be released only upon the substitution of cash, purchase money obligations, or certain other property or upon the basis of available additions or available retirements of bonds.

Subject to the terms and conditions contained in the Mortgage, we:

• may, at any time, without the consent of the Trustee, sell, exchange, or otherwise dispose of, free from the lien of the Mortgage, any property subject to the lien of the Mortgage, which has become worn out, unserviceable, undesirable, or unnecessary for use in the conduct of our business; upon replacing or modifying such property, such replacement or modified property shall without further action become subject to the lien of the Mortgage;

• may, at any time, sell, exchange, or dispose of any property (except cash, securities, or other personal property pledged or deposited with or required to be pledged or deposited with the Trustee), and the Trustee shall release such property from the operation and lien of the Mortgage upon receipt by the Trustee of certain documents and, subject to certain exceptions, cash in an amount equal to the fair value of such property;

• shall, in the event any property is taken by the exercise of the power of eminent domain or otherwise purchased or ordered to be sold by any governmental body, deposit with the Trustee the award for or proceeds of any property so taken, purchased or sold, and such property shall be released from the lien of the Mortgage;

• may, at any time, without the consent of the Trustee, sell, exchange, or otherwise dispose of any property (except cash, securities, or other personal property pledged or deposited with or required to be pledged or deposited with the Trustee) subject to the lien of the Mortgage which is no longer used or useful in the conduct of our business, provided the fair values of the property so sold, exchanged, or otherwise disposed of in any one calendar year shall not exceed $50,000 and cash in an amount equal to the fair value of the property is deposited with the Trustee; and

• may, in lieu of depositing cash with the Trustee as required above, deliver to the Trustee purchase money obligations secured by a mortgage on the property to be released or disposed of, a certificate of the Trustee or other holder of a prior lien on any part of the property to be released stating that a specified amount of cash or purchase money obligations have been deposited with such Trustee or other holder, or certain other certificates from us.

Subject to certain conditions specified in the Mortgage, moneys deposited with the Trustee may be:

• withdrawn by us to the extent of available additions and available first mortgage bond retirements;

• withdrawn by us in amount equal to the lower of cost or fair value of property additions acquired or constructed by us; and

• used to purchase or redeem first mortgage bonds of any series.

Notwithstanding the foregoing, proceeds received by the Trustee from a sale or disposition of substantially all of our electric properties at Portland, Oregon, may be applied only to the retirement of first mortgage bonds outstanding under the Mortgage.

Modification of the Mortgage

Under the Mortgage, our rights and obligations and the rights of the holders of the bonds may be modified with the consent of the holders of 75% in aggregate principal amount of the outstanding first mortgage bonds, including the consent of holders of 60% in aggregate principal amount of the first mortgage bonds of each series affected by the modification. No modification of the principal or interest payment terms, no modification permitting the creation of any lien not otherwise permitted under the Mortgage, and no modification reducing the

18

TABLE OF CONTENTS

percentage required for modifications, will be effective without the consent of the holders of all first mortgage bonds then outstanding. The Mortgage may also be modified in various other respects not inconsistent with the Mortgage and which do not adversely affect the interests of the holders of bonds.

Consolidation, Merger, and Conveyance of Assets

The terms of the Mortgage do not preclude us from merging or consolidating with, or from transferring all of the trust estate substantially as an entirety to, a corporation lawfully entitled to acquire and operate our utility assets (a “successor corporation”), provided that the lien and security of the Mortgage and the rights and powers of the Trustee and the holders of the bonds continue unimpaired. Any such merger, consolidation, or transfer, if it involves a successor corporation owning property subject to existing liens, must comply with the requirements of the Mortgage relating to the acquisition of property subject to a prior lien, which requirements are described in the third paragraph under “Secured Obligations” above. At or before the time of any such merger, consolidation, or transfer permitted by the Mortgage, the successor corporation must execute and record a supplemental indenture with the Trustee pursuant to which the successor corporation assumes all of our obligations under the Mortgage and agrees to pay the bonds in accordance with their terms. Thereafter, the successor corporation will have the right to issue additional first mortgage bonds under the Mortgage in accordance with its terms, and all such first mortgage bonds shall have the same legal rank and security as the bonds and the other first mortgage bonds issued under the Mortgage. Property acquired by the successor corporation after a merger, consolidation, or transfer described above shall not be subject to the lien of the Mortgage unless expressly made a part of the trust estate pursuant to a supplemental indenture.

The Mortgage does not contain any provisions that afford holders of bonds special protection in the event that we consummate a highly leveraged transaction; however, the bonds would continue to be entitled to the benefit of a first priority lien on the property subject to the Mortgage (other than property acquired by us subject to a prior lien) as described above.

Defaults and Notice

Each of the following will constitute a default:

• failure to pay the principal when due;

• failure to pay interest for 60 days after it is due;

• failure to deposit any sinking or replacement fund payment for 60 days after it is due;

• certain events in bankruptcy, insolvency, or reorganization of us; and

• failure to perform any other covenant in the Mortgage that continues for 60 days after being given written notice, including the failure to pay any of our other indebtedness.

The Trustee may withhold notice to the holders of first mortgage bonds of any default (except in payment of principal, interest, or any sinking or purchase fund installment) if it in good faith determines that withholding notice is in the interest of the holders of the first mortgage bonds issued under the Mortgage.

If an event of default occurs and continues, the Trustee or the holders of at least 25% in aggregate principal amount of the first mortgage bonds may declare the entire principal and accrued interest due and payable immediately. If this happens, subject to certain conditions, the holders of a majority of the aggregate principal amount of the first mortgage bonds can annul the declaration and its consequences.

No holder of first mortgage bonds may enforce the lien of the Mortgage, unless (i) it has given the Trustee written notice of default, (ii) the holders of 25% of the first mortgage bonds have requested the Trustee to act and have offered the Trustee reasonable indemnity, and (iii) the Trustee has failed to act within 60 days. The holders of a majority in principal amount of the first mortgage bonds may direct the time, method, and place of conducting any proceeding or any remedy available to the Trustee, or exercising any power conferred upon the Trustee.

Evidence to be Furnished to the Trustee

Compliance with Mortgage provisions is evidenced by the written statements of our officers or persons we selected and paid. In certain cases, opinions of counsel and certificates of an engineer, accountant, appraiser, or

19

TABLE OF CONTENTS

other expert (who in some instances must be independent) must be furnished. Various certificates and other papers are required to be filed annually and upon the occurrence of certain events, including an annual certificate with respect to compliance with the terms of the Mortgage and the absence of defaults.

Interest and Payment

The prospectus supplement will set forth:

• the interest rate or rates or the method of determination of the interest rate or rates of the bonds;

• the date or dates on which the interest is payable; and

• the office or agency in the Borough of Manhattan, City and State of New York at which interest will be payable.

Concerning the Trustee

Computershare Trust Company, National Association (as successor to Wells Fargo Bank, National Association) is the Trustee under the Mortgage. We maintain ordinary banking relationships and credit facilities with Wells Fargo Bank, National Association. The holders of a majority in principal amount of the outstanding first mortgage bonds issued under the Mortgage may direct the time, method, and place of conducting any proceeding for exercising any remedy available to the Trustee, subject to certain exceptions. The Mortgage provides that if default occurs (and it is not cured), the Trustee will be required, in the exercise of its power, to use the degree of care of a prudent person in the conduct of such person’s own affairs. Subject to these provisions, the Trustee will be under no obligation to exercise any of its rights or powers under the Mortgage at the request of any holder of securities issued under the Mortgage, unless that holder has offered to the Trustee security and indemnity satisfactory to it against any loss, liability, or expense, and then only to the extent required by the terms of the Mortgage. The Trustee may resign from its duties with respect to the Mortgage at any time or may be removed by us. If the Trustee resigns, is removed, or becomes incapable of acting as Trustee or a vacancy occurs in the office of the Trustee for any reason, a successor Trustee shall be appointed in accordance with the provisions of the Mortgage.

Governing Law

The Mortgage provides that it and any bonds issued thereunder are governed by, and construed in accordance with, the laws of the state of New York, except to the extent the Trust Indenture Act of 1939 otherwise applies.

Other Expenses of Issuance and Distribution.

The following table sets forth the estimated expenses (all of which will be borne by the registrant unless otherwise provided in the applicable prospectus supplement) incurred in connection with the issuance and distribution of the securities being registered, other than underwriting discounts and commissions (if any). All of the amounts shown are estimates, except the SEC registration fee:

Pursuant to Rules 456(b) and 457(r) under the Securities Act of 1933, as amended, the SEC registration fee will be paid at the time of any particular offering of securities under the registration statement, and is therefore not currently determinable.

**
These fees are calculated based on the securities offered and the number of issuances and accordingly cannot be estimated at this time.

Item 15.
Indemnification of Directors and Officers.

Section 60.394 of the Oregon Business Corporation Act provides that unless limited by its articles of incorporation, a corporation shall indemnify a director who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which the director was a party because of being a director of the corporation against reasonable expenses incurred by the director in connection with the proceeding. Section 60.407 of the Oregon Business Corporation Act provides that unless limited by its articles of incorporation an officer of the corporation is entitled to the same mandatory indemnification under Section 60.394 as a director. Our Articles of Incorporation do not limit the indemnification provided under Section 60.394 or Section 60.407 of the Oregon Business Corporation Act. Article VII of our Articles of Incorporation provides that, to the fullest extent permitted by law, no director of the Company shall be personally liable to the Company or its shareholders for monetary damages for conduct as a director.

Section 60.391 of the Oregon Business Corporation Act authorizes a corporation to indemnify an individual made a party to a proceeding because the individual is or was a director against liability incurred in the proceeding if: (a) the conduct of the individual was in good faith; (b) the individual reasonably believed that the individual’s conduct was in the best interests of the corporation, or at least not opposed to its best interests; and (c) in the case of any criminal proceeding, the individual had no reasonable cause to believe the individual’s conduct was unlawful. Indemnification is not permitted under Section 60.391 (i) in connection with a proceeding by or in the right of the corporation in which the director was adjudged liable to the corporation or (ii) in connection with any other proceeding charging improper personal benefit to the director in which the director was adjudged liable on the basis that personal benefit was improperly received by the director. Article VIII of our Articles of Incorporation provides that the Company may indemnify to the fullest extent permitted by law any person who is made or threatened to be made a party to, witness in, or otherwise involved in, any action, suit, or proceeding, whether civil, criminal, administrative, investigative, or otherwise (including an action, suit, or proceeding by or in the right of the Company) by reason of the fact that the person is or was a director, officer, employee or agent of the Company or any of its subsidiaries, or a fiduciary within the meaning of the Employee Retirement Income Security Act of 1974, as amended, with respect to any employee benefit plan of the Company or any of our subsidiaries, or serves or served at the request of the Company as a director, officer, employee or agent, or as a fiduciary of an employee benefit plan, of another corporation, partnership, joint venture, trust or other enterprise. Section 6.1 of our Bylaws provides that the Company shall indemnify, to the fullest extent not prohibited by applicable law, each current or former officer or director who is made or threatened to be made a party to an action, suit, or proceeding, whether civil, criminal, administrative, investigative, or otherwise (including an

TABLE OF CONTENTS

action, suit, or proceeding by or in the right of the company) by reason of the fact that the person is or was acting as a director, officer or agent of the Company or as a fiduciary within the meaning of the Employee Retirement Income Security Act of 1974, as amended, with respect to any employee benefit plan of the company, or serves or served at the request of the Company as a director, officer, or as a fiduciary of an employee benefit plan, of another corporation, partnership, joint venture, trust or other enterprise.

In addition, Section 60.411 of the Oregon Business Corporation Act provides that a corporation (i) may purchase and maintain insurance on behalf of an individual against liability asserted against or incurred by the individual who is or was a director, officer, employee or agent of the corporation or who, while a director, officer, employee or agent of the corporation, is or was serving at the request of the corporation as a director, officer, partner, trustee, employee or agent of another foreign or domestic corporation, partnership, joint venture, trust, employee benefit plan or other enterprise and (ii) may purchase and maintain the insurance even if the corporation has no power to indemnify the individual against the same liability under Section 60.391 or Section 60.394.

Section 6.8 of our Bylaws provides that, to the fullest extent permitted by the Oregon Business Corporation Act, the company, upon approval by the Board of Directors, may purchase insurance on behalf of any person required or permitted to be indemnified pursuant to Article VI of the Bylaws.

The Company has entered into an agreement with each of its directors and executive officers that requires the Company to indemnify such persons against any expense or liability, including judgments, fines, penalties, interest, counsel fees and disbursements, amounts paid or to be paid in settlement, and excise taxes and penalties under the Employment Retirement Income Security Act of 1974, paid or incurred in connection with investigating, defending, being a witness in, or participating in, or preparing for any of the foregoing in, any proceeding relating to any event or occurrence by reason of the fact that such person is or was a director or officer of the Company, or is or was serving at the request of the company in certain capacities. The indemnification agreements also set forth certain procedures that will apply in the event of a claim for indemnification thereunder.

The Company has procured directors’ and officers’ liability insurance. The coverage provided by these policies indemnifies the Company to protect it against liability assumed or incurred under the above indemnification provisions, including defense provisions, on behalf of the directors and officers against loss arising from any civil claim or claims by reason of any wrongful act done or alleged to have been done while acting in their respective capacities as directors or officers. The policies also provide direct coverage to the directors and officers against certain liabilities, including liabilities arising under the Securities Act, which might be incurred by them in such capacities and against which they cannot be indemnified by the Company. The policies exclude claims brought about or contributed to by dishonest, fraudulent, criminal or malicious acts or omissions by directors or officers.

In connection with an offering of the securities registered hereunder, the registrant may enter into an underwriting agreement which may provide that the underwriters are obligated, under certain circumstances, to indemnify directors, officers and controlling persons of the registrant against certain liabilities, including liabilities under the Securities Act of 1933.

Please also see the undertakings set out in response to Item 17 herein.

Undertakings.

(a)
The undersigned registrant hereby undertakes:

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

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

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

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

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

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

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

(5)
That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(A)
Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B)
Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify

II-3

any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6)
That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)
Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)
Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)
The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)
Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b)
The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report, pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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

The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Act.
