This prospectus supplement, the accompanying prospectus and any related free writing prospectus have been prepared on the basis that any offer of notes in any Member State of the European Economic Area (the “EEA”) will only be made to a legal entity that is a qualified investor under the Prospectus Regulation (“EEA Qualified Investors”). Accordingly, any person making or intending to make an offer in that Member State of notes that are the subject of the offering contemplated in this prospectus supplement, the accompanying prospectus and any related free writing prospectus may only do so with respect to EEA Qualified Investors. Neither Exelon nor the underwriters have authorized, nor do they authorize, the making of any offer of notes other than to EEA Qualified Investors.

PROHIBITION OF SALES TO EEA RETAIL INVESTORS — The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Regulation. Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

These forward-looking statements are based on assumptions, expectations and assessments made by our management in light of their experience and their perception of historical trends, current conditions, expected future developments and other factors they believe to be appropriate. Any forward-looking statements are not guarantees of our future performance and are subject to risks and uncertainties.

Accordingly, any such statements are qualified in their entirety by reference to, and are accompanied by, the following important factors that may cause our actual results or outcomes to differ materially from those contained in our forward-looking statements, including, but not limited to:

•

unfavorable legislative and/or regulatory actions;

•

uncertainty as to outcomes and timing of regulatory approval proceedings and/or negotiated settlements thereof;

•

environmental liabilities and remediation costs;

•

state and federal legislation requiring use of low-emission, renewable, and/or alternate fuel sources and/or mandating implementation of energy conservation programs requiring implementation of new technologies;

•

challenges to tax positions taken, tax law changes, and difficulty in quantifying potential tax effects of business decisions;

•

negative outcomes in legal proceedings;

•

physical security and cybersecurity risks;

•

extreme weather events, natural disasters, operational accidents such as wildfires or natural gas explosions, war, acts and threats of terrorism, public health crises, epidemics, pandemics, or other significant events;

•

disruptions or cost increases in the supply chain, including shortages in labor, materials or parts, or significant increases in relevant tariffs;

•

lack of sufficient power generation resources to meet actual or forecasted demand or disruptions at generation facilities owned by third parties;

•

emerging technologies that could affect or transform the energy industry;

•

instability in capital and credit markets;

•

a downgrade of Exelon’s credit ratings or other failure to satisfy the credit standards in Exelon’s agreements or regulatory financial requirements;

•

significant economic downturns or increases in customer rates;

•

impacts of climate change and weather on energy usage and maintenance and capital costs; and

•

impairment of long-lived assets, goodwill, and other assets.

New factors emerge from time to time, and it is impossible for us to predict all of such factors, nor can we assess the impact of each such factor on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. For more information about the factors that could cause actual results to differ materially from the forward-looking statements made by Exelon, see the factors discussed herein, as well as the items discussed in (1) Exelon’s 2025 Annual Report on Form 10-K in (a) Part I, ITEM 1A.

THE OFFERING

The following summary contains basic information about the notes and this offering. It does not contain all of the information that may be important to you. For a more complete understanding of this offering, we encourage you to read this entire prospectus supplement the accompanying prospectus and any related free writing prospectus required to be filed with the SEC, including “Description of the Notes.”

Issuer

Exelon Corporation

Securities Offered

$775,000,000 aggregate principal amount of 4.950% notes due 2036

Maturity Date

The notes will mature on March 15, 2036

Interest Rate

4.950% per annum

Interest Payment Dates

Interest on the notes will be paid semi-annually on March 15 and September 15 of each year, beginning on September 15, 2026, and on the maturity date.

Optional Redemption

At any time prior to December 15, 2035, (the “Par Call Date”) we may redeem any of the notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

•

(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points, less (b) interest accrued to the date of redemption; and

•

100% of the principal amount of the notes then outstanding to be redeemed,

plus accrued and unpaid interest thereon to the redemption date.

On or after the Par Call Date, we may redeem the notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued and unpaid interest thereon to the redemption date. See “Description of the Notes — Optional Redemption.”

Ranking

The notes will be our direct unsecured general obligations and will rank equally with all of our existing and future unsecured and unsubordinated debt, will be senior in right of payment to all of our existing and future subordinated debt and will be junior to any of our future secured debt to the extent of the value of the collateral securing such secured debt. Because we are a holding company with no material assets other than our ownership interests in our subsidiaries and all of our operations are conducted by our subsidiaries, our debt is effectively subordinated to all existing and future debt, trade creditors, and other liabilities of our subsidiaries. Our rights, and hence the rights of our creditors, to participate in any distribution of assets of any subsidiary upon its liquidation or reorganization or otherwise would be subject to the prior claims of that subsidiary’s creditors, except to the extent that our claims as a creditor of such subsidiary may be recognized. As of December 31, 2025, our subsidiaries had outstanding approximately $35.2 billion of long-term debt, including long-term debt to financing trusts and

S-7

TABLE OF CONTENTS

the portion of long-term debt due within one year. The notes will not be obligations of or guaranteed by any of our subsidiaries. The Indenture (as defined below) does not limit our ability to issue debt or the amount of debt we or our subsidiaries may issue.

Denominations

The notes will be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Additional Notes

Subject to the limitations described in this prospectus supplement and the accompanying prospectus, we may issue additional notes under the Indenture with the same priority as the notes offered hereby, including notes having the same series designation and terms (except for the public offering prices and the issue date) as the notes offered hereby, without the approval of the holders of outstanding notes under the Indenture, including the holders of the outstanding notes offered hereby.

No Listing

We do not intend to list the notes on any securities exchange or automated dealer quotation system. The notes will be new securities for which there currently is no public market. See “Risk Factors — There may be no public market for the notes.”

Use of Proceeds

Any remainder of the net proceeds will be used for general corporate purposes. See “Use of Proceeds.”

Risk Factors

You should consider carefully all the information set forth and incorporated by reference in this prospectus supplement and the accompanying prospectus and, in particular, you should evaluate the specific factors set forth under the heading “Risk Factors” beginning on page S-9 of this prospectus supplement, as well as the other information contained or incorporated herein by reference, before investing in the notes offered hereby.

Trustee

The Bank of New York Mellon Trust Company, N.A.

Governing Law

The Indenture and the notes will be governed by the laws of the State of New York.

S-8

TABLE OF CONTENTS

RISK FACTORS

Investing in the notes involves risks. You should carefully consider the following discussion and the risks described under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2025, incorporated by reference in this prospectus supplement and the accompanying prospectus, the factors listed under “Forward Looking Statements” in this prospectus supplement and the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus before making a decision to invest in the notes. There may be other risks and uncertainties not known to us or that we deem immaterial that also could impair our business operations, financial results and the value of our securities. See “Where You Can Find More Information.”

General market conditions may adversely affect the market prices of the notes and there may be no public market for the notes.

There is no established trading market for the notes, and the underwriters are not obligated to make a market in the notes. We do not intend to apply for listing of the notes on any securities exchange. The underwriters have advised us that they intend to make a market in the notes but are not obligated to do so and may discontinue such market-making activities at any time without notice. We can give no assurances concerning the future market prices of the notes, the liquidity of any markets that may develop for the notes offered by this prospectus supplement, the ability of any investor to sell any of the notes or the price at which investors would be able to sell them. The condition of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future, which could have an adverse effect on the market prices of the notes. If a market for the notes does not develop, investors may be unable to resell the notes for an extended period of time, if at all. If a market for the notes does develop, it may not continue or they may not be sufficiently liquid to allow holders to resell any of the notes. Consequently, investors may not be able to liquidate their investment readily, and lenders may not readily accept the notes as collateral for loans.

The Indenture does not restrict the amount of additional debt that we may incur.

The notes and Indenture pursuant to which the notes will be issued do not place any limitation on the amount of indebtedness that we or our subsidiaries may incur. Our incurrence of additional debt may have important consequences for you as a holder of the notes, including making it more difficult for us to satisfy our obligations with respect to the notes, a loss in the trading value of your notes and a risk that one or more of the credit ratings of the notes are lowered or withdrawn.

Our debt, including the notes, is effectively subordinated to the debt of our subsidiaries.

Because we are a holding company with no material assets other than our ownership interests in our subsidiaries and all of our operations are conducted by our subsidiaries, our debt is effectively subordinated to all existing and future debt, trade creditors, and other liabilities of our subsidiaries. Our rights, and hence the rights of our creditors, to participate in any distribution of assets of any subsidiary upon its liquidation or reorganization or otherwise would be subject to the prior claims of that subsidiary’s creditors, except to the extent that our claims as a creditor of such subsidiary may be recognized. As of December 31, 2025, our subsidiaries had outstanding approximately $35.2 billion of long-term debt, including long-term debt to financing trusts and the portion of long-term debt due within one year. The Indenture does not restrict our or our subsidiaries’ ability to incur additional indebtedness.

S-9

TABLE OF CONTENTS

USE OF PROCEEDS

We estimate that the net proceeds from the sale of the notes in this offering will be approximately $766,947,750, after deducting the underwriting discounts and commissions but before deducting other offering expenses. The net proceeds from the sale of the notes, together with available cash balances, will be used to retire our $750,000,000 3.400% Notes due 2026 at maturity. Any remainder of the net proceeds will be used for general corporate purposes. To the extent we do not use the net proceeds immediately, we may temporarily invest them in short-term, interest-bearing obligations.

DESCRIPTION OF THE NOTES

The following description of the notes is only a summary and is not intended to be comprehensive. In the event that information in this prospectus supplement is inconsistent with information in the accompanying prospectus, you should rely on this prospectus supplement.

General

We will issue $775,000,000 of the 4.950% notes due 2036 under an indenture, which is a contract between us and the trustee, The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), dated June 11, 2015 as will be supplemented by the supplemental indenture dated as of February 1, 2026 and as it may be further supplemented from time to time, which is referred to herein collectively as the “Indenture.” Subject to the limitations described in this prospectus supplement and the accompanying prospectus, we may issue additional notes under the Indenture with the same priority as the notes offered hereby, including notes having the same series designation and terms (except for the public offering prices and the issue date) as the notes offered hereby, without the approval of the holders of outstanding notes under the Indenture, including the holders of the outstanding notes offered hereby.

The terms of the notes will not necessarily afford you protection in the event of particular transactions or upon the occurrence of particular events that may adversely affect you, including a reorganization, recapitalization, restructuring, merger or other similar transactions involving us or our subsidiaries, whether or not in connection with a change of control. As a result, we could enter into such transactions even though the transaction could adversely affect our capital structure or credit ratings or otherwise adversely affect the holders of the notes. The notes will not contain any provisions that will require us to redeem, or permit the holders of the notes to cause a redemption or purchase of, the notes upon the occurrence of any particular event. However, we may redeem some or all of the notes at any time or from time to time prior to maturity, at our option, as described in this prospectus supplement under “— Optional Redemption” below.

Interest Rate and Maturity

The notes will pay interest at the fixed rate of 4.950% per annum. Interest on the notes will be payable semi-annually on March 15 and September 15 of each year, beginning on September 15, 2026. The notes will mature on March 15, 2036.

Interest on the notes will accrue from and include the date that the notes are issued to and excluding the date of maturity or redemption. Interest will be computed on the basis of a 360-day year of twelve 30-day months. On each interest payment date, we will pay interest on each note to the person in whose name the note is registered at the close of business on the record date for such interest. The record date for each interest payment date in respect of the notes will be the close of business on the Business Day immediately preceding the applicable interest payment date. If any interest payment date falls on a day that is not a Business Day, payment will be made on the next Business Day and no additional interest or other payment will be paid in respect of such delay. “Business Day” means any day that is not a Saturday, a Sunday or a day on which commercial banking institutions in New York City are generally authorized or required by law or executive order to be closed.

long-term debt, including long-term debt to financing trusts and the portion of long-term debt due within one year. The Indenture does not restrict our or our subsidiaries’ ability to incur additional indebtedness. In addition, the notes will not be obligations of or guaranteed by any of our subsidiaries. The Indenture does not limit our ability to issue secured debt senior to the notes or the amount of debt we or our subsidiaries may issue, whether secured or unsecured.

Please see “Capitalization” in this prospectus supplement for information with respect to the long-term debt of us and our subsidiaries as of December 31, 2025.

Form and Denomination

The notes will be issued in registered form in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The notes will initially be issued in “book-entry only form,” represented by a permanent global debt security registered in the name of DTC, including Clearstream and/or Euroclear, or its nominee. However, we reserve the right to issue notes in certificated form registered in the name of the noteholders. For so long as the notes are registered in the name of DTC or its nominee, we will pay the principal, premium, if any, and interest due on the notes to DTC for payment to its participants for subsequent disbursement to the beneficial owners. For further information on DTC and its practices, see “Book-Entry System” below.

Optional Redemption

At any time prior to December 15, 2035 (the “Par Call Date”), we may redeem any of the notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

•

100% of the principal amount of the notes then outstanding to be redeemed,

plus, in each case, accrued and unpaid interest thereon to the redemption date.

Any optional redemption may be conditioned upon the consummation of one or more other transactions, including any debt or equity issuance by us or any of our parent companies or subsidiaries. The Trustee shall not have responsibility for calculating any redemption price.

“Treasury Rate” means, with respect to any redemption date, the yield determined by us in accordance with the following two paragraphs.

The Treasury Rate shall be determined by us after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities — Treasury constant maturities — Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, we shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields — one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life — and shall interpolate to the Par Call Date on a straight-line basis (using the actual number

S-13

TABLE OF CONTENTS

of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, we shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Our actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of notes to be redeemed.

In the case of a partial redemption, notes in definitive form will be selected for redemption by lot by the Trustee. No notes of a principal amount of $2,000 or less will be redeemed in part. If any note in definitive form is to be redeemed in part only, the notice of redemption that relates to such note will state the portion of the principal amount of the note to be redeemed. A new note in definitive form in a principal amount equal to the unredeemed portion of the original note in definitive form will be issued in the name of the holder of such note upon surrender for cancellation of the original definitive note. For so long as the notes are in global form and held by DTC (or another depositary), the redemption of the notes, including the selection of notes in the case of a partial redemption, shall be done in accordance with the policies and procedures of the depositary. Unless we default in payment of the redemption price, on and after the redemption date interest will cease to accrue on the notes or portions thereof called for redemption.

Events of Default

An “Event of Default” with respect to a series of debt securities issued under the Indenture means any of the following:

•

we fail to pay the principal of (or premium, if any, on) any debt security of that series when due and payable;

•

we fail to pay any interest on any debt security of that series for 30 days after such is due;

•

we fail to observe or perform any other covenants or agreements set forth in the debt securities of that series, or in the Indenture in regard to such debt securities, continuously for 90 days after notice (which must be sent either by the Trustee or holders of at least 33% of the principal amount of the affected series);

•

S-14

TABLE OF CONTENTS

aggregating $100 million or more which default is not cured, waived or postponed pursuant to an agreement with the holders of the Indebtedness within 30 days after written notice as provided in the Indenture, or the acceleration is not rescinded or annulled within 30 days after written notice as provided in the Indenture; or

•

we file for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur.

As used in the immediately preceding paragraph, “Indebtedness” means all obligations for borrowed money.

An Event of Default for a particular series of debt securities does not necessarily mean that an Event of Default has occurred for any other series of debt securities issued under the Indenture. If an Event of Default has occurred and has not been cured, the Trustee or the holders of not less than 33% of the principal amount of the debt securities of the affected series may declare the entire principal of the debt securities of such series due and payable immediately. Subject to certain conditions, if we deposit with the Trustee enough money to remedy the default and there is no default continuing, this acceleration of payment may be rescinded by the holders of at least a majority in aggregate principal amount of the debt securities of such series.

The Trustee must, within 90 days after a default occurs, notify the holders of the debt securities of the series of the default if we have not remedied it (default is defined to include the events specified above without the grace periods or notice). The Trustee may withhold notice to the holders of such debt securities of any default (except in the payment of principal or interest) if it in good faith considers such withholding in the interest of the holders. We are required to file an annual certificate with the Trustee, signed by an officer, stating any default by us under any provisions of the Indenture.

Prior to any declaration of acceleration of maturity, the holders holding a majority of the principal amount of the debt securities of the particular series affected, on behalf of the holders of all debt securities of that series, may waive any past default or Event of Default. We cannot, however, obtain a waiver of a payment default.

Other than the duty to act with the required standard of care during an event of default, the Trustee is not required to take any action under the Indenture at the request of any holders unless such holders offer the Trustee reasonable indemnity. Subject to the provisions for indemnification and certain other limitations, the holders of a majority in principal amount of the debt securities of any series may direct the time, method and place of conducting any proceedings for any remedy available to the Trustee with respect to such debt securities.

In order to bypass the Trustee and take steps to enforce your rights or protect your interests relating to the debt securities, the following must occur:

•

you must give the Trustee written notice that an Event of Default has occurred and remains uncured;

•

the holders of 33% of the principal amount of all outstanding debt securities of the relevant series must make a written request that the Trustee take action because of the default, and must offer reasonable indemnity to the Trustee against the cost and other liabilities of taking that action; and

•

the Trustee must have not taken action for 60 days after receipt of the above notice and offer of indemnity.

However, you are entitled at any time to bring a lawsuit for the payment of money due on your debt security on or after its due date.

“Street name” and other indirect holders should consult their banks or brokers for information on how to give notice or direction to, or make a request of, the Trustee and to make or cancel a declaration of acceleration.

Supplemental Indentures

There are three types of changes we can make to the Indenture and the debt securities issued thereunder, including the notes.

S-15

TABLE OF CONTENTS

Changes Requiring Each Holder’s Approval

The following changes require the approval of each holder of debt securities of the series affected then outstanding:

•

extending the fixed maturity of any debt security;

•

reducing the interest rate or extending the time of payment of interest;

•

reducing any premium payable upon redemption;

•

reducing the principal amount;

•

reducing the amount of principal payable upon acceleration of the maturity of a discounted debt security following default;

•

changing the currency of payment on a debt security; or

•

reducing the percentage of securityholders whose consent is required to modify or amend the Indenture.

Changes Not Requiring Holder Approval

Changes not requiring holder approval are limited to those changes specified in the Indenture, including those which are of an administrative nature or are changes that would not adversely affect holders of the debt securities.

Changes Requiring a Majority of all Holders to Approve

A vote in favor by securityholders owning a majority of the principal amount of the debt securities of a particular series of affected debt securities is required for any other matter listed in the Indenture.

Consolidation, Merger or Sale

We may not merge or consolidate with any person (as defined in the Indenture) or sell substantially all of our assets as an entirety unless:

•

we are the continuing corporation or the successor person is organized under the laws of the United States or a state or is organized under the laws of a foreign jurisdiction and consents to the jurisdiction of the courts of the United States or a state and expressly assumes the payment of principal, and premium, if any, and interest on the debt securities and the performance and observance of all the covenants and conditions of the Indenture binding on us; and

•

we, or the successor person, are not immediately after the merger, consolidation or sale in default in the performance of a covenant or condition in the Indenture binding on us.

Discharge, Defeasance and Covenant Defeasance

We may discharge certain obligations to holders of the notes of a series that have not already been delivered to the Trustee for cancellation and that either have become due and payable or will become due and payable within one year (or scheduled for redemption within one year) by irrevocably depositing with the Trustee, in trust, funds in U.S. dollars in an amount sufficient to pay the entire indebtedness including, but not limited to, the principal and premium, if any, and interest to the date of such deposit (if the debt securities have become due and payable) or to the maturity thereof or the redemption date of the debt securities of that series, as the case may be. We may direct the Trustee to invest such funds in U.S. Treasury securities with a maturity of one year or less or in a money market fund that invests solely in short-term U.S. Treasury securities.

The Indenture provides that we may elect either (1) to defease and be discharged from any and all obligations with respect to the notes of a series (except for, among other things, obligations to maintain an office or agency with respect to the debt securities and to hold moneys for payment in trust) (“legal defeasance”) or (2) to be released from our obligations to comply with the restrictive covenants under the

S-16

TABLE OF CONTENTS

Indenture, and any omission to comply with such obligations will not constitute a default or an event of default with respect to the notes of a series and such related clause under “— Events of Default” will no longer be applied (“covenant defeasance”). Legal defeasance or covenant defeasance, as the case may be, will be conditioned upon, among other things, the irrevocable deposit by us with the Trustee, in trust, of an amount in U.S. dollars, or U.S. government obligations, or both, applicable to the debt securities of that series which through the scheduled payment of principal and interest in accordance with their terms will provide money in an amount sufficient to pay the principal or premium, if any, and interest on the notes on the scheduled due dates therefor.

If we effect covenant defeasance with respect to the notes of any series, the amount in U.S. dollars, or U.S. government obligations, or both, on deposit with the Trustee will be sufficient, in the opinion of a nationally recognized firm of independent accountants, to pay amounts due on the notes of that series at the time of the stated maturity but may not be sufficient to pay amounts due on the notes of that series at the time of the acceleration resulting from such event of default. However, we would remain liable to make payment of such amounts due at the time of acceleration.

We will be required to deliver to the Trustee an opinion of counsel that the deposit and related defeasance will not cause the holders and beneficial owners of the notes of that series to recognize income, gain or loss for federal income tax purposes. If we elect legal defeasance, that opinion of counsel must be based upon a ruling from the U.S. Internal Revenue Service or a change in law to that effect.

We may exercise our legal defeasance option notwithstanding our prior exercise of our covenant defeasance option.

Open Market Purchases

We may acquire the notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the Indenture.

Governing Law

The Indenture and the notes will be governed by the laws of the State of New York.

Concerning the Trustee

We and our affiliates use or may use some of the banking services of the Trustee in the normal course of business.

Book-Entry System

We will issue the notes in the form of one or more global notes in fully registered form initially in the name of Cede & Co., as nominee of DTC, or such other name as may be requested by an authorized representative of DTC. The global notes will be deposited with DTC and may not be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any nominee to a successor of DTC or a nominee of such successor.

DTC, the world’s largest securities depository, is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for U.S. and non-U.S. equity, corporate and municipal debt issues, and money market instruments that DTC’s participants (direct participants) deposit with DTC. DTC also facilitates the post-trade settlement among direct participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between direct participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (DTCC). DTCC is the holding company for DTC, National

S-17

TABLE OF CONTENTS

Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly (indirect participants). The rules applicable to DTC and its direct and indirect participants are on file with the SEC. More information about DTC can be found at www.dtcc.com. We do not intend this internet address to be an active link or to otherwise incorporate the content of the website into this prospectus supplement.

Clearstream advises that it is incorporated under the laws of Luxembourg as a bank. Clearstream holds securities for its customers and facilitates the clearance and settlement of securities transactions between its customers through electronic book-entry transfers between their accounts. Clearstream provides to its customers among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic securities markets in over 30 countries through established depository and custodial relationships. As a bank, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector, also known as the Commission de Surveillance du Secteur Financier. Its customers are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Its customers in the United States are limited to securities brokers and dealers and banks. Indirect access to Clearstream is also available to other institutions such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with the customer.

Euroclear advises that it was created in 1968 to hold securities for its participants and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V.. Euroclear Clearance establishes policy for Euroclear on behalf of Euroclear participants. Euroclear participants include banks, including central banks, securities brokers and dealers and other professional financial intermediaries and may include the Initial purchasers. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly. Securities clearance accounts and cash accounts with the Euroclear operator are governed by the terms and conditions governing use of Euroclear and the related operating procedures of Euroclear. These terms and conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear operator acts under the terms and conditions only on behalf of Euroclear participants and has no record of or relationship with persons holding through Euroclear participants.

Euroclear further advises that investors that acquire, hold and transfer interests in the notes by book-entry through accounts with the Euroclear operator or any other securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between such an intermediary and each other intermediary, if any, standing between themselves and the global securities.

Purchases of notes under the DTC system must be made by or through direct participants, which will receive a credit for the notes in DTC’s records. The ownership interest of each actual purchaser of notes (beneficial owner) is in turn to be recorded on the direct and indirect participants’ records. Beneficial owners of the notes will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participant through which the beneficial owner entered into the transaction. Transfers of ownership interests in the notes are to be accomplished by entries made on the books of direct and indirect participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the notes, except in the event that use of the book-entry system for the notes is discontinued.

S-18

TABLE OF CONTENTS

To facilitate subsequent transfers, all notes deposited by direct participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of notes with DTC and their registration in the name of Cede & Co. or such other nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the notes; DTC’s records reflect only the identity of the direct participants to whose accounts such notes are credited, which may or may not be the beneficial owners. The direct and indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. The laws of some jurisdictions may require that certain persons take physical delivery in definitive form of securities which they own. Consequently, those persons may be prohibited from purchasing beneficial interests in the global notes from any beneficial owner or otherwise.

Redemption notices shall be sent to DTC. If less than all of the notes within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in such issue to be redeemed.

So long as DTC’s nominee is the registered owner of the global notes, such nominee for all purposes will be considered the sole owner or holder of the notes for all purposes under the Indenture. Except as provided below, beneficial owners will not be entitled to have any of the notes registered in their names, will not receive or be entitled to receive physical delivery of the notes in definitive form and will not be considered the owners or holders thereof under the Indenture.

Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or vote with respect to the notes. Under its usual procedures, DTC mails an omnibus proxy to the issuer as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts the notes are credited on the record date (identified in a listing attached to the omnibus proxy).

All payments on the global notes will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from trustees or issuers on payment dates in accordance with their respective holdings shown on DTC’s records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participant and not of DTC, the Trustee or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal and interest to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) shall be the responsibility of the Trustee or us, disbursement of such payments to direct participants shall be the responsibility of DTC, and disbursement of such payments to the beneficial owners shall be the responsibility of direct and indirect participants.

DTC may discontinue providing its service as securities depositary with respect to the notes at any time by giving reasonable notice to us or the Trustee. In addition, we may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depositary). In the event that a successor securities depositary is not obtained under the above circumstances, or, alternatively, if an event of default with respect to the notes has occurred and is outstanding, note certificates in fully registered form are required to be printed and delivered to beneficial owners of the global notes representing such notes.

Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC’s rules and will be settled in immediately available funds using DTC’s same-day funds settlement system. Secondary market trading between Clearstream customers and/or Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional Eurobonds in immediately available funds.

Cross market transfers between persons holding directly or indirectly through DTC on the one hand, and directly or indirectly through Clearstream customers or Euroclear participants, on the other, will be

S-19

TABLE OF CONTENTS

effected in DTC in accordance with DTC’s rules on behalf of the relevant European international clearing system by its U.S. depositary; however, such cross market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines, in European time. The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depository to take action to effect final settlement on its behalf by delivering interests in the notes to or receiving interests in the notes from DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream customers and Euroclear participants may not deliver instructions directly to their respective U.S. depositaries.

Because of time-zone differences, credits of interests in the notes received by Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the Business Day following the DTC settlement date. Such credits or any transactions involving interests in such notes settled during such processing will be reported to the relevant Clearstream customers or Euroclear participants on such Business Day. Cash received by Clearstream or Euroclear as a result of sales of interests in the notes by or through a Clearstream customer or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the Business Day following settlement in DTC.

The information in this section has been obtained from sources that we believe to be reliable, but we take no responsibility for its accuracy.

Neither we, the Trustee nor the underwriters will have any responsibility or obligation to direct participants, or the persons for whom they act as nominees, with respect to the accuracy of the records of DTC, its nominee or any direct participant with respect to any ownership interest in the notes, or payments to, or the providing of notice to direct participants or beneficial owners.

TABLE OF CONTENTS

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of the material United States federal income tax considerations relating to the purchase, ownership and disposition of the notes, but does not purport to be a complete analysis of all potential tax considerations. This summary is based on the United States Internal Revenue Code of 1986, as amended (the “Code”), the Treasury regulations promulgated thereunder, judicial authority, published administrative positions of the United States Internal Revenue Service (the “IRS”) and other applicable authorities, all as in effect on the date of this document, and all of which are subject to change, possibly on a retroactive basis. We have not sought, and will not seek, any ruling from the IRS with respect to the statements made and the conclusions reached in the following summary and there can be no assurance that the IRS will agree with our statements and conclusions or that a court would not sustain any challenge by the IRS in the event of litigation.

This summary deals only with beneficial owners of notes that acquire the notes for cash in this offering at their issue price (generally, the first price at which a substantial amount of the notes are sold for money to investors (excluding sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers)) and that will hold the notes as “capital assets” within the meaning of section 1221 of the Code (generally, property held for investment). This summary does not purport to deal with all aspects of United States federal income taxation that might be relevant to particular beneficial owners in light of their personal investment circumstances or status, nor does it address tax considerations applicable to beneficial owners that may be subject to special tax rules, such as banks and financial institutions, individual retirement and other tax-deferred accounts, tax-exempt entities, governments or government instrumentalities, S corporations, partnerships or other pass-through entities for United States federal income tax purposes or investors in such entities, insurance companies, regulated investment companies, real estate investment trusts, broker-dealers, dealers or traders in securities or currencies, certain former citizens or residents of the United States subject to section 877 of the Code, controlled foreign corporations, non-United States trusts or estates with United States beneficiaries, passive foreign investment companies, corporations that accumulate earnings to avoid United States federal income tax, taxpayers subject to the alternative minimum tax, and persons subject to special tax accounting rules as a result of their use of applicable financial statements within the meaning of section 451(b)(3) of the Code. This summary also does not discuss notes held as part of a hedge, straddle, synthetic security, constructive sale transaction or conversion transaction, situations in which the “functional currency” of a United States Holder (as defined below) is not the United States dollar or situations where a United States Holder (as defined below) holds a note through a bank, financial institution or other entity or a branch thereof, that is located, organized or resident outside the United States. Moreover, the effect of any United States federal non- income taxes (such as estate or gift taxes) and any state, local or non-United States tax laws or tax treaties are not discussed.

The following discussion assumes that the notes will be issued with no (or de minimis) original issue discount. If, however a note’s stated principal amount exceeds its issue price by an amount that is greater than or equal to a specified de minimis amount, as determined under applicable Treasury regulations, a United States Holder would be required to include the excess in income as original issue discount, as it accrues, in accordance with a constant-yield method based on a compounding of interest before the receipt of cash payments attributable to this income.

In the case of a beneficial owner of notes that is classified as a partnership for United States federal income tax purposes, the tax treatment of the notes to a partner in the partnership generally will depend upon the tax status of the partner and the activities of the partner and the partnership. If you are a partner of a partnership holding notes, then you should consult your own tax advisors about the United States federal income tax consequences to you of the purchase, ownership and disposition of the notes by the partnership.

The following discussion is for informational purposes only and is not a substitute for careful tax planning and advice. Investors considering the purchase of notes should consult their own tax advisors with respect to the application of the United States federal income tax laws to their particular situations, as well as any tax consequences arising under any other federal tax laws or the laws of any state, local or non- United States taxing jurisdiction or under any applicable tax treaty, and the possible effects of changes in United States federal tax laws, or in any applicable tax treaty.

TABLE OF CONTENTS

Effect of Certain Contingencies

In certain circumstances, we may be required to pay amounts in excess of stated interest and principal on the notes. Our obligation to pay such excess amounts may implicate the provisions of the Treasury regulations relating to “contingent payment debt instruments” (“CPDIs”) in which case the timing and amount of income inclusions and the character of income recognized may be different from the consequences discussed herein. However, under these Treasury regulations, one or more contingencies will not cause the notes to be treated as CPDIs if, as of the issue date of such notes, such contingencies, in the aggregate, are considered remote or incidental. Although the issue is not free from doubt, we intend to take the position that the possibility of payment of such excess amounts should be treated as remote and/or incidental and do not result in the notes being treated as CPDIs under applicable Treasury regulations.

Our position that these contingencies are remote or incidental is binding on a holder, unless such holder explicitly discloses to the IRS on its tax return for the taxable year during which it acquires the notes that it is taking a different position. However, this determination is inherently factual and we can give you no assurance that our position would be sustained if challenged by the IRS. A successful challenge of this position by the IRS may require a holder to accrue ordinary interest income on the notes at a rate in excess of the stated interest rate, and to treat any gain realized on the sale, exchange, redemption, retirement or other taxable disposition of the notes as ordinary income rather than capital gain. Holders of notes should consult their own tax advisors regarding the tax consequences of the notes being treated as CPDIs. The remainder of this discussion assumes that the notes will not be treated as CPDIs for United States federal income tax purposes.

The following is a summary of certain United States federal income tax considerations for a United States Holder. For purposes of this summary, the term “United States Holder” means a beneficial owner of a note that is, for United States federal income tax purposes:

•

an individual who is a citizen or a resident of the United States, including an alien individual who is a lawful permanent resident of the United States or meets the “substantial presence” test under section 7701(b) of the Code;

•

a corporation, or any other entity treated as a corporation for United States federal income tax purposes, created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•

an estate, the income of which is subject to United States federal income taxation regardless of its source; or

•

a trust, if (1) a court within the United States is able to exercise primary jurisdiction over its administration and one or more “United States persons” (within the meaning of the Code) have the authority to control all of its substantial decisions, or (2) the trust has a valid election in place under applicable Treasury regulations to be treated as a domestic trust for United States federal income tax purposes.

Taxation of stated interest on a note

Stated interest on a note generally will be included in the gross income of a United States Holder as ordinary income at the time such interest is accrued or received, in accordance with the United States Holder’s method of tax accounting for United States federal income tax purposes.

Sale, exchange, redemption, retirement or other taxable disposition of a note

Upon the sale, exchange, redemption, retirement or other taxable disposition of a note, a United States Holder generally will recognize gain or loss equal to the difference, if any, between (1) the amount realized on the disposition, except any portion of such amount that is attributable to accrued but unpaid interest, which will be taxed as ordinary interest income to the extent not previously so taxed, and (2) the United States Holder’s adjusted tax basis in the note. A United States Holder’s adjusted tax basis in a note generally will equal the cost of the note to such United States Holder, reduced by any principal payments on the

S-22

TABLE OF CONTENTS

note received by such United States Holder. Any such gain or loss generally will be long-term capital gain or loss if, at the time of such disposition, the United States Holder has held the note for more than one year. Individuals and other non-corporate taxpayers are, under certain circumstances, subject to United States federal income tax on long-term capital gains at a reduced tax rate. The deductibility of capital losses is subject to limitations. Each United States Holder should consult its own tax advisors as to the deductibility of capital losses in its particular circumstances.

Information reporting and backup withholding

In general, we must report certain information to the IRS with respect to payments of stated interest and payments of the proceeds of the sale or other taxable disposition (including a retirement or redemption) of a note to certain United States Holders, except in the case of an exempt recipient (such as a corporation). The payor (which may be us or an intermediate payor) will be required to impose backup withholding tax, currently at a rate of 24 percent, with respect to the foregoing amounts if (1) the payee fails to furnish a taxpayer identification number (“TIN”) to the payor or to establish an exemption from backup withholding, (2) the IRS notifies the payor that the TIN furnished by the payee is incorrect, (3) there has been a notified payee underreporting described in section 3406(c) of the Code or (4) the payee has not certified under penalties of perjury that it has furnished a correct TIN, that it is a United States person and that the IRS has not notified the payee that it is subject to backup withholding under the Code. Backup withholding tax is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a United States Holder will be allowed as a credit against the holder’s United States federal income tax liability, if any, and may entitle the United States Holder to a refund, provided that the required information is timely furnished to the IRS. United States Holders should consult their own tax advisors regarding the effect, if any, of the backup withholding rules on their particular circumstances.

Medicare contribution tax

An additional 3.8 percent tax will be imposed on certain United States Holders who are individuals, estates or trusts (other than certain exempt trusts or estates) on the lesser of (1) the United States Holder’s “net investment income” (or undistributed net investment income in the case of an estate or trust) for the relevant taxable year and (2) the excess of the United States Holder’s modified adjusted gross income (or adjusted gross income in the case of an estate or trust) for the taxable year over a certain threshold. A United States Holder’s net investment income will generally include its interest income (including interest paid on a note) and its net gains from the disposition of notes, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). If you are a United States Holder that is an individual, estate or trust, you should consult your tax advisor regarding the applicability of the Medicare contribution tax to your income and gains in respect of your investment in the notes.

Non-United States Holders

The following is a summary of certain United States federal income tax considerations for a non- United States Holder. For purposes of this summary, the term “non-United States Holder” means a beneficial owner of a note that is, for United States federal income tax purposes:

•

a nonresident alien individual;

•

a foreign corporation; or

•

a foreign estate or trust.

The following discussion assumes that no item of income, gain, deduction or loss derived by any non- United States Holder in respect of the notes at any time is effectively connected with the conduct of a United States trade or business. Non-United States Holders with any item of income, gain, deduction or loss in respect of the notes that is effectively connected with the conduct of a United States trade or business should consult their own tax advisors regarding the United States federal income and branch profits tax consequences of the purchase, ownership and disposition of the notes.

Payment of interest

Subject to the discussions on backup withholding and FATCA (as defined below), interest paid on a note by us or any paying agent to a non-United States Holder will be exempt from United States income and withholding tax under the “portfolio interest exemption” provided that (1) the non-United States Holder does not, actually or constructively, own 10 percent or more of the total combined voting power of all classes of our stock entitled to vote, (2) the non-United States Holder is not a controlled foreign corporation related to us, actually or constructively, through stock ownership, (3) the non-United States Holder is not a bank that acquired the notes in consideration for an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business and (4) either (a) the non-United States Holder provides to us or our paying agent an applicable properly completed IRS Form W-8BEN or W-8BEN-E (or applicable successor form) and any applicable attachments, signed under penalties of perjury, that includes its name and address and that certifies that it is not a United States person or in the case of an individual, that the person is neither a citizen or a resident (for United States federal income tax purposes) of the United States, in compliance with applicable law and regulations, or (b) a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business on behalf of the non-United States Holder provides a statement to us or our agent under penalties of perjury in which it certifies that a properly completed applicable IRS Form W-8BEN or W-8BEN-E (or applicable successor form) has been received by it from the non-United States Holder or (c) the non-United States Holder holds its notes through a “qualified intermediary” and the qualified intermediary furnishes a copy to us or our agent of a properly executed IRS Form W-8IMY (or applicable successor form) and any applicable attachments on behalf of itself (which may, in some circumstances, include a withholding statement and applicable underlying IRS forms sufficient to establish that the non-United States Holder is not a United States Holder). This certification requirement may be satisfied with other documentary evidence in the case of a note held as an offshore obligation or through certain foreign intermediaries, if certain requirements are met. If a non-United States Holder cannot satisfy the requirements of the portfolio interest exemption described above, payments of interest made to such non-United States Holder generally will be subject to United States withholding tax at the rate of 30 percent, unless the non-United States Holder provides us or our agent with a properly executed IRS Form W-8BEN or W-8BEN-E or applicable successor form) establishing an exemption from, or reduction of the withholding tax under the benefit of an applicable tax treaty.

Sale, exchange, redemption, retirement or other disposition of a note

Subject to the discussions on backup withholding tax and FATCA below, a non-United States Holder generally will not be subject to United States federal income tax or withholding tax on any gain realized on a sale, exchange, redemption, retirement or other taxable disposition of a note (other than any amount representing accrued but unpaid interest on the note, which is subject to the rules discussed above under “— Payment of interest”). However, if a non-United States Holder is an individual who is present in the United States for 183 days or more in the taxable year of the disposition, and certain other requirements are met, such non-United States Holder generally will be subject to United States federal income tax at a flat rate of 30 percent (unless a lower applicable treaty rate applies) on any such non-United States Holder’s United States-source gain, which may be offset by certain United States-source losses.

Information reporting and backup withholding

The amount of interest on a note paid to a non-United States Holder and the amount of tax, if any, withheld from such payment generally must be reported annually to the non-United States Holder and to the IRS, even if such non-United States Holder is exempt from the 30 percent withholding tax described above. The IRS may make this information available under the provisions of an applicable income tax treaty to the tax authorities in the country in which the non-United States Holder is resident.

Provided that a non-United States Holder has complied with certain reporting procedures (usually satisfied by providing an applicable properly completed IRS Form W-8BEN or IRS Form W-8BEN-E) or otherwise establishes an exemption, the non-United States Holder generally will not be subject to backup withholding tax with respect to interest payments on, and the proceeds from a disposition of, a note, unless we or our paying agent know or have reason to know that the holder is a United States person. Rules relating

S-24

TABLE OF CONTENTS

to information reporting requirements and backup withholding with respect to the payment of proceeds from the taxable disposition (including a redemption or retirement) of a note are as follows:

•

If the proceeds are paid to or through the United States office of a broker, a non-United States Holder generally will be subject to backup withholding and information reporting unless the non- United States Holder certifies under penalties of perjury that it is not a United States person (usually on an IRS Form W-8BEN or W-8BEN-E) or otherwise establishes an exemption.

•

If the proceeds are paid to or through a non-United States office of a broker that is not a United States person and does not have certain specified United States connections (a “United States Related Person”), a non-United States Holder will not be subject to backup withholding or information reporting.

•

If the proceeds are paid to or through a non-United States office of a broker that is a United States person or a United States Related Person, a non-United States Holder generally will be subject to information reporting (but generally not backup withholding) unless the non-United States Holder certifies under penalties of perjury that it is not a United States person (usually on an IRS Form W-8BEN) or otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a credit against the non-United States Holder’s United States federal income tax liability, if any, and may entitle the non-United States Holder to a refund, provided that the required information is timely furnished to the IRS. Non-United States Holders should consult their own tax advisors regarding the application of the backup withholding rules in their particular circumstances and the availability of, and procedure for, obtaining an exemption from backup withholding under current Treasury regulations.

“FATCA” legislation

Sections 1471 through 1474 of the Code and the final Treasury regulations and official IRS guidance associated with such provisions (such provisions, regulations and guidance commonly known as FATCA) generally imposes a United States federal withholding tax of 30 percent on interest income paid on a debt obligation, such as the notes, to (1) a foreign financial institution (as the beneficial owner or as an intermediary for the beneficial owner), unless such institution (a) enters into, and is in compliance with, a withholding and information reporting agreement with the United States government to collect and provide to the United States tax authorities substantial information regarding United States account holders of such institution (which would include certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with United States owners) or (b) is a resident in a country that has entered into an intergovernmental agreement with the United States in relation to such withholding and information reporting and the financial institution complies with the related information reporting requirements of such country or (2) a foreign entity that is not a financial institution (as the beneficial owner or as an intermediary for the beneficial owner), unless such entity provides the withholding agent with a certification identifying the substantial United States owners of the entity, which generally includes any United States person who directly or indirectly owns more than 10 percent of the entity or certifies that it does not have any substantial United States owners. The IRS has issued proposed regulations (on which taxpayers may rely until final regulations are issued) that would generally not apply these withholding requirements to gross proceeds from the disposition of assets such as the notes.

The United States federal income tax discussion set forth above is included for general information only and may not be applicable depending upon a holder’s particular situation. Prospective holders of the notes should consult their own tax advisors with respect to the tax consequences to them of the ownership and disposition of the notes, including the tax consequences under state, local, foreign and other tax laws, any applicable tax treaties and the possible effects of changes in United States or other tax laws.

UNDERWRITING

BNP Paribas Securities Corp., Morgan Stanley & Co. LLC, and Wells Fargo Securities, LLC are acting as representatives of the several underwriters set forth below. Subject to the terms and conditions contained in an underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters and the underwriters have severally and not jointly agreed to purchase from us the principal amount of the notes listed opposite their names below:

Underwriter	Principal Amount of Notes
BNP Paribas Securities Corp.		$	191,167,000
Morgan Stanley & Co. LLC			191,167,000
Wells Fargo Securities, LLC			191,166,000
BNY Mellon Capital Markets, LLC			56,834,000
Huntington Securities, Inc.			56,834,000
Siebert Williams Shank & Co., LLC			56,833,000
Apto Partners, LLC			10,333,000
Loop Capital Markets LLC			10,333,000
Samuel A. Ramirez & Company, Inc.			10,333,000
Total		$	775,000,000

The obligations of the several underwriters to purchase the notes are subject to certain conditions as set forth in the underwriting agreement. The underwriters are obligated to purchase all of the notes if they purchase any of the notes. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of the non-defaulting underwriter may be increased or the offering of notes may be terminated. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

We expect to deliver the notes on or about the date specified on the cover page of this prospectus supplement, which will be the second business day following the date of this prospectus supplement (T+2). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of this prospectus supplement will be required, by virtue of the fact that the notes initially will settle in T+2, to specify an alternate settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.

The underwriters have advised us that they propose to initially offer the notes to the public at the relevant price to public appearing on the cover page of this prospectus supplement and may also offer the notes to certain securities dealers at the relevant price to public on the cover of this prospectus supplement less a concession of 0.400% of the principal amount of the notes. The underwriters may allow, and such dealers may re-allow, a discount to certain brokers and dealers not in excess of 0.250% of the principal amount of the notes. After the initial public offering, the relevant price to public, concession and discount may be changed.

In connection with the offering, the underwriters may engage in transactions that stabilize the price of the notes. These transactions may include purchases for the purpose of fixing or maintaining the price of the notes.

S-26

TABLE OF CONTENTS

The underwriters may create a short position in the notes in connection with the offering. That means they sell a larger principal amount of the notes than is shown on the cover page of this prospectus supplement. If they create a short position, the underwriters may purchase notes in the open market to reduce the short position.

If the underwriters purchase the notes to stabilize the price or to reduce their short position, the price of the notes could be higher than it might be if they had not made such purchases. The underwriters make no representation or prediction about any effect that purchases may have on the price of the notes and any of such transactions may be discontinued at any time.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the underwriters or their affiliates have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

We have agreed to indemnify the several underwriters against certain civil liabilities, including liabilities under the Securities Act of 1933, or to contribute with respect to payments which the underwriters may be required to make in respect of any of those liabilities.

Our expenses associated with the offer and sale of the notes, excluding underwriting discounts, are estimated to be approximately $1.5 million.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities. From time to time, in the ordinary course of business, the underwriters and their respective affiliates have engaged and may in the future engage, in sales and trading, commercial banking, investment banking advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services and/or other transactions of a financial nature with us and our affiliates. Consequently, they have received, and in the future may continue to receive, customary fees and commissions for these services. The underwriters or their affiliates may provide credit to us or our affiliates as lenders from time to time, including under our existing revolving credit facility. BNY Mellon Capital Markets, LLC, one of the underwriters participating in the offering, is an affiliate of the trustee.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

The prospectus supplement may also add, update or change information contained in this prospectus. If there is any inconsistency between the information in this prospectus and the prospectus supplement, you should rely on the prospectus supplement. You should read both this prospectus and any prospectus supplement together with additional information described under “Where You Can Find More Information.”

Information contained herein relating to each registrant is filed separately by such registrant on its own behalf. No registrant makes any representation as to information relating to any other registrant or Securities issued by any other registrant.

TABLE OF CONTENTS

FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated or deemed incorporated by reference as described under the heading “Where You Can Find More Information” contain forward-looking statements within the meaning of federal securities laws. Words such as “could,” “may,” “expects,” “anticipates,” “will,” “targets,” “goals,” “projects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “predicts,” “should,” and variations on such words, and similar expressions that reflect our current views with respect to future events and operational, economic and financial performance, are intended to identify forward-looking statements but are not the only means to identify those statements. These forward- looking statements are based on assumptions, expectations and assessments made by our management in light of their experience and their perception of historical trends, current conditions, expected future developments and other factors they believe to be appropriate. Any forward-looking statements are not guarantees of our future performance and are subject to risks and uncertainties. Accordingly, any such statements are qualified in their entirety by reference to, and are accompanied by, the following important factors that may cause our actual results or outcomes to differ materially from those contained in our forward-looking statements, including, but not limited to:

•

unfavorable legislative and/or regulatory actions;

•

uncertainty as to outcomes and timing of regulatory approval proceedings and/or negotiated settlements thereof;

•

environmental liabilities and remediation costs;

•

challenges to tax positions taken, tax law changes, and difficulty in quantifying potential tax effects of business decisions;

•

negative outcomes in legal proceedings;

•

adverse impact of the activities associated with the past deferred prosecution agreement and now-resolved SEC investigation on Exelon’s and ComEd’s reputation and relationships with legislators, regulators, and customers;

•

physical security and cybersecurity risks;

•

extreme weather events, natural disasters, operational accidents such as wildfires or natural, gas explosions, war, acts and threats of terrorism, public health crises, epidemics, pandemics, or other significant events;

•

lack of sufficient capacity to meet actual or forecasted demand or disruptions at power generation facilities owned by third parties;

•

emerging technologies that could affect or transform the energy industry;

•

instability in capital and credit markets;

•

a downgrade of any registrant’s credit ratings or other failure to satisfy the credit standards in the registrants’ agreements or regulatory financial requirements;

•

significant economic downturns or increases in customer rates;

•

impacts of climate change and weather on energy usage and maintenance and capital costs; and

•

impairment of long-lived assets, goodwill, and other assets.

New factors emerge from time to time, and it is impossible for us to predict all of such factors, nor can we assess the impact of each such factor on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. For more information about the factors that could cause actual results to differ materially from the forward-looking statements made by Exelon and ComEd, see the factors discussed herein, as well as the items discussed in (1) the registrants’ 2024 Annual Report on Form 10-K in (a) Part I, ITEM 1A. Risk Factors, (b) Part II, ITEM 7. Management’s Discussion and Analysis of Financial Condition and Results of

Operations, and (c) Part II, ITEM 8. Financial Statements and Supplementary Data: Note 18, Commitments and Contingencies and (2) other factors discussed in filings with the Securities and Exchange Commission by the registrants.

You are cautioned not to place undue reliance on these forward-looking statements, which apply only as of the date on the front of this prospectus or, as the case may be, as of the date on which we make any subsequent forward-looking statement that is deemed incorporated by reference. We do not undertake any obligation to update or revise any forward-looking statement to reflect events or circumstances after the date as of which any such forward-looking statement is made.

TABLE OF CONTENTS

DESCRIPTION OF SECURITIES

EXELON DEBT SECURITIES

The Exelon debt securities will be our direct, unsecured obligations and may be issued from time to time in one or more offerings of one or more series of either senior debt securities or subordinated debt securities.

SENIOR DEBT SECURITIES

The senior debt securities will be issued under an Indenture between us and The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), dated June 11, 2015 (“Senior Indenture”). The Senior Indenture has been filed as exhibit to the registration statement of which this prospectus is a part. Selected provisions of the Senior Indenture have been summarized below. The summary is not complete and many of the terms contained in the following summary may be modified in the accompanying prospectus supplement. You should read the Senior Indenture for provisions that may be important to you.

Ranking

The senior debt securities will be Exelon’s direct unsecured general obligations and will rank equally with all of our existing and future unsecured and unsubordinated debt, will be senior in right of payment to all of our existing and future subordinated debt and will be junior to any of our future secured debt to the extent of the value of the collateral securing such secured debt. Because we are a holding company with no material assets other than our ownership interests in our subsidiaries and all of our operations are conducted by our subsidiaries, our debt is effectively subordinated to all existing and future debt, trade creditors, and other liabilities of our subsidiaries. Our rights, and hence the rights of our creditors, to participate in any distribution of assets of any subsidiary upon its liquidation or reorganization or otherwise would be subject to the prior claims of that subsidiary’s creditors, except to the extent that our claims as a creditor of such subsidiary may be recognized. The Senior Indenture does not restrict our or our subsidiaries’ ability to incur additional indebtedness.

Events of Default

An “Event of Default” with respect to a series of senior debt securities issued under the Senior Indenture means any of the following:

•

we fail to pay the principal of (or premium, if any, on) any senior debt security of that series when due and payable;

•

we fail to pay any interest on any senior debt security of that series for 30 days after such is due;

•

we fail to observe or perform any other covenants or agreements set forth in the senior debt securities of that series, or in the Senior Indenture in regard to such debt securities, continuously for 90 days after notice (which must be sent either by the Trustee or holders of at least 33% of the principal amount of the affected series);

•

our failure to pay principal at maturity or acceleration following a default in an aggregate amount of $100 million or more with respect to any Indebtedness (as defined below) of Exelon Corporation (not including Indebtedness of our subsidiaries), or the acceleration of any of our Indebtedness aggregating $100 million or more which default is not cured, waived or postponed pursuant to an agreement with the holders of the Indebtedness within 30 days after written notice as provided in the Senior Indenture, or the acceleration is not rescinded or annulled within 30 days after written notice as provided in the Senior Indenture; or

•

we file for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur.

As used in the immediately preceding paragraph, “Indebtedness” means all obligations for borrowed money.

An Event of Default for a particular series of senior debt securities does not necessarily mean that an Event of Default has occurred for any other series of senior debt securities issued under the Senior Indenture.

TABLE OF CONTENTS

If an Event of Default has occurred and has not been cured, the Trustee or the holders of not less than 33% of the principal amount of the senior debt securities of the affected series may declare the entire principal of the senior debt securities of such series due and payable immediately. Subject to certain conditions, if we deposit with the Trustee enough money to remedy the default and there is no default continuing, this acceleration of payment may be rescinded by the holders of at least a majority in aggregate principal amount of the senior debt securities of such series.

The Trustee must, within 90 days after a default occurs, notify the holders of the senior debt securities of the series of the default if we have not remedied it (default is defined to include the events specified above without the grace periods or notice). The Trustee may withhold notice to the holders of such senior debt securities of any default (except in the payment of principal or interest) if it in good faith considers such withholding in the interest of the holders. We are required to file an annual certificate with the Trustee, signed by an officer, stating any default by us under any provisions of the Senior Indenture.

Prior to any declaration of acceleration of maturity, the holders holding a majority of the principal amount of the senior debt securities of the particular series affected, on behalf of the holders of all senior debt securities of that series, may waive any past default or Event of Default. We cannot, however, obtain a waiver of a payment default.

Other than the duty to act with the required standard of care during an event of default, the Trustee is not required to take any action under the Senior Indenture at the request of any holders unless such holders offer the Trustee such reasonable indemnity as it may require. Subject to the provisions for indemnification and certain other limitations, the holders of a majority in principal amount of the senior debt securities of any series may direct the time, method and place of conducting any proceedings for any remedy available to the Trustee with respect to such senior debt securities.

In order to bypass the Trustee and take steps to enforce your rights or protect your interests relating to the senior debt securities, the following must occur:

•

you must give the Trustee written notice that an Event of Default has occurred and remains uncured;

•

the holders of 33% of the principal amount of all outstanding senior debt securities of the relevant series must make a written request that the Trustee take action because of the default, and must offer reasonable indemnity to the Trustee against the cost and other liabilities of taking that action; and

•

the Trustee must have not taken action for 60 days after receipt of the above notice and offer of indemnity.

However, you are entitled at any time to bring a lawsuit for the payment of money due on your senior debt security on or after its due date.

Supplemental Indentures

There are three types of changes we can make to the Senior Indenture and the debt securities issued thereunder.

Changes Requiring Each Holder’s Approval

The following changes require the approval of each holder of senior debt securities of the series affected then outstanding:

•

extending the fixed maturity of any senior debt security;

•

reducing the interest rate or extending the time of payment of interest;

•

reducing any premium payable upon redemption;

TABLE OF CONTENTS

•

reducing the principal amount;

•

reducing the amount of principal payable upon acceleration of the maturity of a discounted senior debt security following default;

•

changing the currency of payment on a senior debt security; or

•

reducing the percentage of securityholders whose consent is required to modify or amend the Senior Indenture.

Changes Not Requiring Holder Approval

Changes not requiring holder approval are limited to the following:

•

to evidence the succession of another corporation to the Issuer, or successive successions;

•

to add to the covenants;

•

to cure any ambiguity;

•

to establish any other provisions as we may deem necessary or desirable; provided that no such action shall adversely affect the interests of the holders of the senior debt securities in any material respect;

•

to evidence and provide for the acceptance of appointment hereunder by a successor trustee;

•

to establish the form or terms of senior debt securities of any series;

•

to make any changes permitted by a supplemental indenture provided such change only affects the series of senior debt securities to which such supplemental indenture applies; and

•

to make any change that would provide any additional rights or benefits to the holders of the senior debt securities.

Changes Requiring a Majority of all Holders to Approve

Except for matters requiring the approval of each holder of senior debt securities of the series affected then outstanding specified above, a vote in favor by securityholders owning a majority of the principal amount of the senior debt securities of a particular series of affected senior debt securities is required for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Senior Indenture or of any supplemental indenture or of modifying in any manner the rights of the holders of the senior debt securities of each such series.

Consolidation, Merger or Sale

We may not merge or consolidate with any person (as defined in the Indenture) or sell substantially all of our assets as an entirety unless:

•

we, or the successor person, are not immediately after the merger, consolidation or sale in default in the performance of a covenant or condition in the Senior Indenture binding on us.

Discharge, Defeasance and Covenant Defeasance

We may discharge certain obligations to holders of the senior debt securities of a series that have not already been delivered to the Trustee for cancellation and that either have become due and payable or will become due and payable within one year (or scheduled for redemption within one year) by irrevocably depositing with the Trustee, in trust, funds in U.S. dollars in an amount sufficient to pay the entire indebtedness

TABLE OF CONTENTS

including, but not limited to, the principal and premium, if any, and interest to the date of such deposit (if the debt securities have become due and payable) or to the maturity thereof or the redemption date of the debt securities of that series, as the case may be.

The Senior Indenture provides that we may elect either (1) to defease and be discharged from any and all obligations with respect to the senior debt securities of a series (except for, among other things, obligations to maintain an office or agency with respect to the senior debt securities and to hold moneys for payment in trust) (“legal defeasance”) or (2) to be released from our obligations to comply with the restrictive covenants under the Senior Indenture, and any omission to comply with such obligations will not constitute a default or an event of default with respect to the senior debt securities of a series and such related clause under “— Events of Default” will no longer be applied (“covenant defeasance”). Legal defeasance or covenant defeasance, as the case may be, will be conditioned upon, among other things, the irrevocable deposit by us with the Trustee, in trust, of an amount in U.S. dollars, or U.S. government obligations, or both, applicable to the senior debt securities of that series which through the scheduled payment of principal and interest in accordance with their terms will provide money in an amount sufficient to pay the principal or premium, if any, and interest on the senior debt securities on the scheduled due dates therefor.

If we effect covenant defeasance with respect to the senior debt securities of any series, the amount in U.S. dollars, or U.S. government obligations, or both, on deposit with the Trustee will be sufficient, in the opinion of a nationally recognized firm of independent accountants, to pay amounts due on the senior debt securities of that series at the time of the stated maturity but may not be sufficient to pay amounts due on the senior debt securities of that series at the time of the acceleration resulting from such event of default. However, we would remain liable to make payment of such amounts due at the time of acceleration.

We will be required to deliver to the Trustee an opinion of counsel that the deposit and related defeasance will not cause the holders and beneficial owners of the debt securities of that series to recognize income, gain or loss for federal income tax purposes. If we elect legal defeasance, that opinion of counsel must be based upon a ruling from the U.S. Internal Revenue Service or a change in law to that effect.

We may exercise our legal defeasance option notwithstanding our prior exercise of our covenant defeasance option.

Governing Law

The Senior Indenture is governed by the laws of the State of New York.

SUBORDINATED DEBT SECURITIES

The subordinated debt securities will be issued under an Indenture between us and The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), dated June 17, 2014 (“Subordinated Indenture”). The Subordinated Indenture has been filed as exhibit to the registration statement of which this prospectus is a part. Selected provisions of the Subordinated Indenture have been summarized below. The summary is not complete and many of the terms contained in the following summary may be modified in the accompanying prospectus supplement. You should read the Subordinated Indenture for provisions that may be important to you.

Events of Default

The Events of Default and related provisions in the Subordinated Indenture will apply to the subordinated debt securities including:

failure to pay interest, on any note within 30 days after the same becomes due and payable (whether or not payment is prohibited by the subordination provisions of the Subordinated Indenture); provided, however, that a valid extension of the interest payment period by the Company as contemplated in the Subordinated Indenture shall not constitute a default in the payment of interest for this purpose; or

failure to pay the principal of or premium, if any, on any note when it becomes due and payable (whether or not payment is prohibited by the subordination provisions of the Subordinated Indenture); or

TABLE OF CONTENTS

failure to perform, or breach of, any covenant or warranty of the Company in the Subordinated Indenture (other than a covenant or warranty a default in the performance of which or breach of which is elsewhere in the applicable section of the indenture specifically dealt with or which has expressly been included in the indenture solely for the benefit of one or more series of securities other than the subordinated debt securities) and the continuance of such default or breach for a period of 90 days after there has been given, by registered or certified mail, to the Company by the Trustee, or to the Company and the Trustee by the holders of at least 33% in principal amount of the outstanding subordinated debt securities, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” under the indenture, unless the Trustee, or the Trustee and the holders of a principal amount of subordinated debt securities not less than the principal amount of subordinated debt securities the holders of which gave such notice, as the case may be, shall agree in writing to an extension of such period prior to its expiration; provided, however, that the Trustee, or the Trustee and the holders of such principal amount of subordinated debt securities, as the case may be, shall be deemed to have agreed to an extension of such period if corrective action is initiated by the Company within such period and is being diligently pursued in good faith; or

the entry by a court having jurisdiction in the premises of (1) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (2) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition by one or more Persons other than the Company seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official for the Company or for any substantial part of its property, or ordering the winding up or liquidation of its affairs, and any such decree or order for relief or any such other decree or order shall have remained unstayed and in effect for a period of 90 consecutive days; or

the commencement by the Company of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company to the entry of a decree or order for relief in respect of the Company in a case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against the Company, or the filing by the Company of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or the consent by the Company to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or similar official of the Company or of any substantial part of its property, or the making by the Company of an assignment for the benefit of creditors, or the admission by the Company in writing of its inability to pay its debts generally as they become due, or the authorization of such action by the Board of Directors of the Company.

The holders of a majority in principal amount of outstanding subordinated debt securities may waive a default or Event of Default, other than a default in the payment of principal of, or interest on, the subordinated debt securities (including the redemption price or purchase price of the subordinated debt securities, if applicable), or a default or Event of Default with respect to a covenant or provision that cannot be modified or amended without the consent of the holder of each outstanding subordinated debt security.

If any portion of the amount payable on the subordinated debt securities upon acceleration is considered by a court to be unearned interest, the court could disallow recovery of such portion.

Consolidation, Merger or Sale

We may not merge or consolidate with any other person or sell or convey all or substantially all of our assets to any person unless (1) either we are the continuing person, or the successor person (if other than us) is organized and existing under the laws of the United States of America or a State thereof or the District of Columbia and expressly assumes the due and punctual payment of the principal of and interest on the

TABLE OF CONTENTS

subordinated debt securities, and the due and punctual performance and observance of all of the covenants and conditions of the indenture to be performed by us by supplemental indenture in form satisfactory to the Trustee, executed and delivered to the Trustee by such person, and (2) we or such successor person, as the case may be, will not, immediately after such merger or consolidation, or such sale or conveyance, be in default in the performance of any such covenant or condition.

In case of any such consolidation, merger or conveyance, such successor person will succeed to and be substituted for us, with the same effect as if it had been named as us in the indenture, and in the event of such conveyance (other than by way of a lease), we will be discharged of all of our obligations and covenants under the indenture and the subordinated debt securities.

Modification of Subordinated Indenture

Without Holder Consent

Without the consent of any holders of subordinated debt securities, we and the Trustee may from time to time amend and/or supplement the Subordinated Indenture and the subordinated debt securities for the following purposes:

•

to evidence the succession of another corporation to us, or successive successions, and the assumption by such successor corporation of our covenants, agreements and obligations pursuant to the provisions described under “— Consolidation, Merger or Sale”;

•

to add to our covenants such further covenants, restrictions or conditions to be for the protection of the holders of the subordinated debt securities, and to make the occurrence, or the occurrence and continuance, of a default in any such additional covenants, restrictions or conditions a default or an Event of Default; provided that such supplemental indenture may provide for a particular grace period or an immediate enforcement upon such default or limit the remedies available to the Trustee upon such default;

•

to change or eliminate any provision of the Subordinated Indenture; provided, however, that any such change or elimination becomes effective only when there are no subordinated debt securities outstanding, or the subordinated debt securities are not entitled to the benefit of such provision;

•

to cure any ambiguity or to correct or supplement any provision contained in the Subordinated Indenture that may be defective or inconsistent with any other provisions contained therein, or to make such other provision in regard to matters or questions arising under the indenture; provided that such action will not adversely affect the interest of the holders of the subordinated debt securities in any material respect;

•

to mortgage or pledge to the Trustee as security for the subordinated debt securities any property or assets that we may desire to mortgage or pledge as security for the subordinated debt securities; and

•

to qualify, or maintain the qualification of, the Subordinated Indenture under the Trust Indenture Act.

With Holder Consent

Under the Subordinated Indenture, supplemental indentures for the purposes of adding any provisions to or changing in any manner or eliminating any of the provisions of the Subordinated Indenture or of modifying in any manner the rights of the holders of the subordinated debt securities under the Subordinated Indenture may be entered into by us, when authorized by board resolution, and the Trustee, with the consent of the holders of not less than a majority in principal amount of the subordinated debt securities. However, no such supplemental indenture shall:

•

change the maturity of the subordinated debt securities, or reduce the rate or extend the time of payment of any interest thereon or on any overdue principal amount or reduce the principal amount thereof, or change theprovisions pursuant to which the rate of interest on the subordinated debt securities is determined if such change could reduce the rate of interest thereon, or reduce the minimum rate of interest thereon (if any), or reduce any amount payable upon any redemption

TABLE OF CONTENTS

thereof, or reduce the amount to be paid at maturity or make the principal thereof or any interest thereon or on any overdue principal amount payable in any coin or currency other than U.S. dollars without the consent of the holder of each subordinated debt security so affected;

•

reduce the percentage of subordinated debt securities, the holders of which are required to consent to any such supplemental indenture, without the consent of the holders of all subordinated debt securities then outstanding;

•

modify any of the provisions of the Subordinated Indenture relating to modifications, waivers of our compliance with covenants thereunder or direction of the Trustee by holders of subordinated debt securities, except to increase the percentage of holders who must consent thereto or to provide that certain other provisions cannot be modified or waived without the consent of the holders of all subordinated debt securities then outstanding; or

•

modify the provisions relating to the subordination of the subordinated debt securities in a manner adverse to the rights of the holders thereof without the consent of the holder of each subordinated debt security so affected.

A supplemental indenture that changes or eliminates any covenant or other provision of the Subordinated Indenture expressly included solely for the benefit of holders of securities other than the subordinated debt securities, or which modifies the rights of the holders of securities other than the subordinated debt securities with respect to such covenant or other provision, will be deemed not to affect the rights under the Subordinated Indenture of the holders of the subordinated debt securities.

We may omit to comply with any covenant or condition contained in the Subordinated Indenture if holders of a majority in principal amount of the subordinated debt securities waive such compliance.

Subordination

The subordinated debt securities will be subordinate and junior in right of payment to all Senior Indebtedness as defined below.

If:

we make a payment or distribution of any of our assets to creditors upon our dissolution, winding-up, liquidation or reorganization, whether in bankruptcy, insolvency or otherwise;

•

a default beyond any grace period has occurred and is continuing with respect to the payment of principal, interest or any other monetary amounts due and payable on any Senior Indebtedness; or

•

the maturity of any Senior Indebtedness has been accelerated because of a default on that Senior Indebtedness,

then the holders of Senior Indebtedness generally will have the right to receive payment of all amounts due on that Senior Indebtedness, or we will make provision for those payments, before the holders of any subordinated debt securities have the right to receive any payments of principal or interest on their subordinated debt securities.

“Senior Indebtedness” means all of our obligations, as the case may be, whether presently existing or from time to time hereafter incurred, created, assumed or existing, to pay principal, premium, interest, penalties, fees and any other payment in respect of any of the following:

•

obligations for borrowed money, including without limitation, such obligations as are evidenced by credit agreements, subordinated debt securities, debentures, bonds or other securities or instruments;

•

capitalized lease obligations;

•

all obligations of the types referred to in clauses (a) and (b) above of others which the we have assumed, endorsed, guaranteed, contingently agreed to purchase or provide funds for the payment of, or otherwise becomes liable for, under any agreement; or

•

all renewals, extensions or refundings of obligations of the kinds described in any of the preceding categories;

TABLE OF CONTENTS

unless, in the case of any particular obligation, indebtedness, renewal, extension or refunding, the instrument creating or evidencing the same or the assumption or guarantee of the same expressly provides that such obligation, indebtedness, renewal, extension or refunding is not superior in right of payment to or is pari passu with the Securities; and provided further that trade accounts payable and accrued liabilities arising in the ordinary course of business shall not be deemed to be Senior Indebtedness.

Senior Indebtedness will be entitled to the benefits of the subordination provisions in the indenture irrespective of the amendment, modification or waiver of any term of the Senior Indebtedness. We may not amend the indenture to change the subordination provisions without the consent of each holder of Senior Indebtedness that the amendment would adversely affect.

Holders of the subordinated debt securities should recognize that contractual provisions in the indenture may prohibit us from making payments on the subordinated debt securities. The subordinated debt securities are subordinate and junior in right of payment, to the extent and in the manner stated in the indenture, to all of our Senior Indebtedness, as defined above.

Governing Law

The Subordinated Indenture is governed by the laws of the State of New York.

EXELON COMMON STOCK

The description below is a summary of certain provisions of our common stock. The Pennsylvania Business Corporation Law and our Amended and Restated Articles of Incorporation and Bylaws determine the rights and privileges of holders of our common stock. We encourage you to read such documents, which have been filed with the SEC and are incorporated herein by reference, and the Pennsylvania law for more information regarding such common stock.

General

Our authorized capital stock consists of 2,000,000,000 shares of common stock, without par value per share. Our common stock is listed on NASDAQ and the Chicago Stock Exchange under the trading symbol “EXC.”

Dividends

Dividends on the common stock will be paid if, when and as determined by our Board of Directors out of funds legally available for this purpose. The rate and timing of future dividends will depend upon our future earnings and financial condition and upon other relevant factors affecting our dividend policy, which we cannot presently determine. As a practical matter, our ability to pay dividends will be governed by the ability of our operating subsidiaries to pay dividends to us.

Voting Rights

Holders of common stock are entitled to one vote for each share held of record by them on all matters presented to shareholders. Pursuant to our Amended and Restated Articles of Incorporation, the holders of common stock do not have cumulative voting rights in the election of directors. Our directors are not classified in respect to the time for which they may hold office. The directors are elected at each annual meeting of shareholders for a one-year term expiring at the next annual meeting of shareholders. Our Bylaws also provide for certain notice requirements for shareholder nominations and proposals at annual meetings and preclude shareholders from bringing business before any special meeting. Certain provisions of Pennsylvania law require a supermajority vote of holders or a majority vote of disinterested directors to approve certain business combinations and other major transactions involving us.

Liquidation Rights

After satisfaction of the preferential liquidation rights of any preferred stock, the holders of our common stock are entitled to share, ratably, in the distribution of all remaining net assets.

TABLE OF CONTENTS

Preemptive and Other Rights

The holders of our common stock do not have preemptive rights as to additional issues of common stock or conversion rights. The shares of our common stock are not subject to redemption or to any further calls or assessments and are not entitled to the benefit of any sinking fund provisions.

Listing

The outstanding shares of our common stock are, and the shares offered hereby will be, listed on NASDAQ.

Transfer Agent and Registrar

The Transfer Agent and Registrar for our common stock is Equiniti Trust Company.

EXELON STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

We may issue stock purchase contracts representing contracts obligating holders to purchase from us, and us to sell to the holders, a specified number of shares of our common stock (or a range of numbers of shares pursuant to a predetermined formula) at a future date or dates. The price per share of common stock and the number of shares of common stock 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.

The stock purchase contracts may be issued separately or as a part of units, often known as stock purchase units, consisting of a stock purchase contract and either:

•

our debt securities; or

•

debt obligations of third parties, including U.S. Treasury securities,

securing the holders’ obligations to purchase the common stock under the stock purchase contracts.

The stock purchase contracts may require us to make periodic payments to the holders of the stock purchase units or vice versa, and such payments may be unsecured or prefunded on some basis. The stock purchase contracts may require holders to secure their obligations in a specified manner and in certain circumstances we may deliver newly issued prepaid stock purchase contracts, often known as prepaid securities, upon release to a holder of any collateral securing such holder’s obligations under the original stock purchase contract.

The applicable prospectus supplement will describe the terms of any stock purchase contracts or stock purchase units and, if applicable, prepaid securities. The description in the applicable prospectus supplement will not contain all of the information that you may find useful. For more information, you should review the stock purchase contracts, the collateral arrangements and depositary arrangements, if applicable, relating to such stock purchase contracts or stock purchase units and, if applicable, the prepaid securities and the document pursuant to which the prepaid securities will be issued. These documents will be filed with the SEC promptly after the offering of the stock purchase contracts or stock purchase units. Material United States federal income tax considerations applicable to the stock purchase contracts and the stock purchase units will also be discussed in the applicable prospectus supplement.

COMED BONDS

The ComEd debt securities will be first mortgage bonds (“bonds”) that will be issued under ComEd’s Mortgage dated July 1, 1923, as amended and supplemented and as further supplemented by a supplemental indenture creating the Bonds. The bonds will bear interest at the rates per annum and will be due and payable on the dates set forth in the applicable prospectus supplement.

We refer to the ComEd Mortgage in this prospectus as the “Mortgage” and to The Bank of New York Mellon Trust Company, N.A. as the “Mortgage Trustee.” The terms “lien of Mortgage,” “mortgage date of

TABLE OF CONTENTS

acquisition,” “permitted lien,” “prior lien,” “prior lien bonds,” “property additions,” and “utilized under the Mortgage” are used in this prospectus with the meanings given to those terms in the Mortgage.

The Mortgage contains provisions under which substantially all of the properties of ComEd’s electric utility subsidiary, Commonwealth Edison Company of Indiana, Inc., or the Indiana Company, might be subjected to the lien of the Mortgage, if we should so determine, as additional security for our bonds, whereupon that subsidiary would become a “mortgaged subsidiary,” as defined in the Mortgage. Since we have not as yet made any determination as to causing the Indiana Company to become a mortgaged subsidiary, those provisions of the Mortgage that are summarized below that discuss a mortgaged subsidiary as well as us, relate to ComEd only.

We have summarized selected provisions of the Mortgage below. However, because this summary is not complete, it is subject to and is qualified in its entirety by reference to the Mortgage. We suggest that you read the complete text of the ComEd Mortgage, a copy of which we have incorporated by reference as an exhibit to the registration statement of which this prospectus is a part.

Securities Offered

The bonds will be secured equally with all other bonds outstanding or hereafter issued under our Mortgage.

Security

The Mortgage is a first mortgage lien on substantially all property and franchises currently owned by ComEd. Our transmission and distribution assets are the principal properties subject to the lien of the Mortgage. In addition, any property and franchises hereafter acquired by us will also become subject to the lien of the Mortgage. The lien of the mortgage does not attach to expressly excepted property, as described in the next paragraph, and property which may be acquired by us subsequent to the filing of a bankruptcy proceeding with respect to us under the Bankruptcy Reform Act of 1978. The lien is also subject to permitted liens, as described below, and, in the case of after-acquired property, liens, if any, existing or placed on that property at the time of acquisition thereof.

There are expressly excepted from the lien of our Mortgage, whether now owned or hereafter acquired, certain real estate not used in the public utility business, real estate held by us in the name of a nominee, cash and securities not specifically pledged under the Mortgage, receivables, contracts (other than leases), materials and supplies not included in utility plant accounts, merchandise, automobiles, trucks and other transportation equipment and office furniture and equipment.

We have agreed under the Mortgage to hold legal title to the mortgaged property free and clear of all liens other than permitted liens, as defined in the Mortgage. Permitted liens are generally liens or restrictions that do not materially interfere with our use of the mortgaged property for the conduct of our business. Permitted liens include liens for real estate taxes, assessments and governmental charges that are not delinquent or are being contested in good faith; liens for judgments that are being appealed or whose enforcement has been stayed; rights reserved to or vested in municipalities or public authorities under franchises, grants, licenses or permits held by us; leases; easements, reservations, exceptions, conditions, limitations and restrictions affecting the mortgaged property which do not materially interfere with our use of the mortgaged property; zoning laws and ordinances; and inconsequential defects or irregularities in title that, in the opinion of our counsel, may be properly disregarded. In the event that the Mortgage lien on a particular piece of mortgaged property were to be foreclosed, such property would remain subject to liens for taxes on that property. Other liens on that property, to the extent prior to the lien of the Mortgage and representing monetary obligations, would be entitled to payment from the foreclosure sale proceeds prior to any sums being paid to the holders of the bonds.

The bonds will rank equally with all bonds, irrespective of series, now or hereafter outstanding under our Mortgage.

Acquisitions of Property Subject to Prior Liens

We covenant in the Mortgage that we will not acquire any property subject to a prior lien (other than a permitted lien):

TABLE OF CONTENTS

•

if the principal amount of prior lien bonds outstanding thereunder and under other prior liens upon such prior lien property exceeds 662∕3% of the fair value of such part of such property as shall consist of property of the character of property additions; and

•

unless the net earnings of such property for any twelve-month period within the immediately preceding fifteen-month period shall have been at least two and one-half times the annual interest on all prior lien bonds secured by prior liens on such property.

We also covenant that we will not transfer all or substantially all of our property to any other corporation, the property of which is subject to a prior lien, unless the property of such other corporation could be acquired by us under the provisions of such covenant with respect to the acquisition of property subject to a prior lien.

We covenant in the Mortgage that we will not issue additional prior lien bonds under any prior lien, and that as soon as all prior lien bonds shall cease to be outstanding under any prior lien, we will promptly procure or cause to be procured the cancellation and discharge of that prior lien. We further covenant that upon the discharge of a prior lien we will cause any cash on deposit with the prior lien trustee (other than cash deposited for the payment or redemption of outstanding prior lien bonds) to be deposited with the Mortgage Trustee, except to the extent required to be deposited with the trustee under another prior lien.

Release of Property from Mortgage

Provided that we are not in default under the Mortgage, the Mortgage allows us to release property from the lien of the Mortgage in connection with its sale or other disposition. Under these provisions, we may obtain the release of mortgaged property by:

•

delivering to the Mortgage Trustee specified certificates describing the property to be sold or disposed and the consideration to be received and stating its fair value;

•

delivering an opinion of counsel as to compliance with the provisions of the Mortgage governing such release; and

•

depositing cash with the Mortgage Trustee in an amount equal to the fair value of the property to be released, subject to reduction or elimination as hereinafter described.

“Fair value” is defined as the fair value to us of the property in question. Fair value is determined by one of our engineers; however, a determination by an independent engineer is also required if the fair value of the property in question exceeds 1% or more of the outstanding principal amount of the bonds under the Mortgage. The required cash deposit may be reduced, or eliminated entirely, by utilizing net property additions or bondable bond retirements not previously utilized under the Mortgage.

We have used these provisions from time to time to release substantial amounts of property from the lien of the Mortgage. In December 1999, we obtained the release of our fossil generation assets in connection with their sale to a third party. In January 2001, we obtained the release of, among other things, our nuclear generation assets in connection with their transfer to our affiliate, Generation, as part of the restructuring undertaken by Exelon. In both cases, the releases were accomplished without the deposit of cash due to the availability of sufficient amounts of unutilized bondable bond retirements and net property additions.

Issuance of Additional Bonds

The Mortgage provides that no bonds may be issued which, as to security, will rank ahead of the bonds that may be sold pursuant to this prospectus but, as indicated below, we may, subject to certain limitations, acquire property subject to prior liens. Nonetheless, subject to the limitations discussed below, we may issue additional bonds under the Mortgage with the same priority as the bonds that may be sold pursuant to this prospectus, including bonds having the same series designation and terms as the bonds that may be sold pursuant to this prospectus, without the approval of the holders of outstanding bonds under the Mortgage, including the holders of any outstanding bonds issued pursuant to this prospectus.

The aggregate principal amount of other bonds that may be issued under the Mortgage and that, as to security, will rank equally with the bonds that may be sold pursuant to this prospectus is not limited except

TABLE OF CONTENTS

as indicated below. Additional bonds of any series may be issued, subject to the provisions of the Mortgage, in principal amount equal to:

•

662∕3% of net property additions not previously utilized under the Mortgage;

•

the amount of cash deposited with the Mortgage Trustee as the basis for the issuance of those bonds; and

•

the amount of bondable bond retirements not previously utilized under the Mortgage;

provided, however, that no bonds may be issued on the basis of net property additions or deposited cash, or on the basis of bondable bond retirements if the bonds to be issued bear a higher rate of interest than that borne by the bonds retired or being retired (except when the bonds retired or being retired mature within two years), unless our net earnings for any twelve-month period within the immediately preceding fifteen-month period shall have been equal to at least two and one-half times the annual interest on all bonds then outstanding under the Mortgage, including the bonds then proposed to be issued but not including any bonds then being retired.

The Mortgage provides that cash deposited with the Mortgage Trustee as a basis for the issuance of bonds shall be:

•

paid over to us in an amount, certified to the Mortgage Trustee, equal to 662∕3% of the amount of net property additions not previously utilized under the Mortgage, or in an amount equal to the amount of bondable bond retirements not previously utilized under the Mortgage, or both, or

•

applied to the purchase or redemption of bonds.

“Net earnings” means our earnings as defined in the Mortgage after deducting all charges except:

•

charges for the amortization, write-down or write-off of acquisition adjustments or intangibles;

•

property losses charged to operations;

•

provisions of income and excess or other profits taxes imposed on income after the deduction of interest charges, or charges made in lieu of those taxes;

•

interest charges; and

•

amortization of debt and stock discount and expense or premium.

Any net profit or net loss from merchandising and jobbing is to be deducted from operating expenses or added to operating expenses, as the case may be.

Net nonoperating income from property and securities not subject to the lien of the Mortgage may be included in revenues but only to the extent of not more than 10% of the total of such net earnings. No profits or losses on the disposition of property or securities or on the reacquisition of securities shall be included in net earnings. The net earnings calculation under the Mortgage is not affected by certain accounting write-offs related to plant costs.

Except as set forth above, the Mortgage does not limit the amount of additional bonds which can be issued and it does not contain any restrictions on the issuance of unsecured indebtedness. In addition, the Mortgage does not prohibit a merger or sale of substantially all of our assets or a comparable transaction, unless the lien of the Mortgage is impaired, and does not address the effect on bondholders of a highly leveraged transaction.

Property Additions/Bondable Bond Retirements

“Bondable bond retirements” means an amount equal to the principal amount of bonds retired by application of funds deposited with the Mortgage Trustee for cancellation, whether or not such deposit of funds or surrender of bonds is pursuant to a sinking fund or purchase fund.

“Net property additions” means the amount of $50,000,000, plus the cost or fair market value as of the mortgage date of acquisition thereof, whichever is less, of property additions, less all “current provisions

TABLE OF CONTENTS

for depreciation” made by us after December 1, 1944, after deducting from those current provisions for depreciation the amount of the “renewal fund requirement,” if any, for the year 1945 and subsequent years.

“Current provisions for depreciation” for any period means the greater of:

•

the total of the amounts appropriated by us for depreciation during that period on all property of the character of property additions not subject to a prior lien, increased or decreased, as the case may be, by net salvage value for that period, such amounts not to include, however, provisions for depreciation charged to surplus, charges to income or surplus for the amortization, write-down or write-off of acquisition adjustments or intangibles, property losses charged to operations or surplus, or charges to income in lieu of income and excess or other profits taxes; and

•

an amount equal to one-twelfth of 2% for each calendar month of that period (or such lesser percentage, as may, at stated intervals, be certified by an independent engineer as adequate) of the original cost, as of the beginning of that month, of all depreciable property of the character of property additions not subject to a prior lien.

Renewal Fund Requirement

We covenant in the Mortgage that we will pay or cause to be paid to the Mortgage Trustee each year an amount of cash equal to the excess, if any, of current provisions for depreciation for that year over the cost or fair market value as of the mortgage date of acquisition thereof, whichever is less, of property additions for that year. That excess amount, which constitutes the renewal fund requirement for that year, is subject to reduction by an amount equal to the amount, certified to the Mortgage Trustee, of net property additions or bondable bond retirements, or both, not previously utilized under the Mortgage. There was no renewal fund requirement for any of the years 1945 through 2011, except as noted in the following table. Any renewal fund requirement was satisfied by certifying an equivalent amount of property additions, except as indicated in the table.

Renewal Fund Requirement
Year	Amount (in millions)			Year		Amount (in millions)			Year		Amount (in millions)
1989		$	140.7		1994		$	193.6		2004		$	270.7
1990			1.0		1995			15.0*
1993			50.9		1996			139.9*

Satisfied by certifying an equivalent amount of bondable bond retirements.

Modification of Mortgage

In general, modifications or alterations of the Mortgage and of the rights and obligations of us and of the bondholders, and waivers of compliance with the Mortgage, may, with our approval, be made at a meeting of bondholders upon the affirmative vote of bondholders owning 80% of the principal amount of the bonds entitled to vote at the meeting with respect to the matter involved, but no such modifications or alterations or waivers of compliance shall be made which will permit the extension of time or times of payment of the principal of or the interest or the premium, if any, on any bonds or the reduction in the principal amount thereof or in the rate of interest or the amount of any premium thereon, or any other modification in the terms of such principal, interest or premium, which terms of payment are unconditional, or, otherwise than as permitted by the Mortgage, the creation of any lien ranking prior to or on a parity with the lien of the Mortgage with respect to any of the mortgaged property, all as more fully provided in the Mortgage.

Concerning the Mortgage Trustee

An affiliate of the Mortgage Trustee provides general banking services, including those as a depository, for us and certain of our affiliates. The affiliate is also one of the lenders under credit agreements with us and our affiliates.

TABLE OF CONTENTS

Rights Upon Default

The Mortgage provides that in case any one or more of certain specified events (defined as “completed defaults”) shall occur and be continuing, the Mortgage Trustee or the holders of not less than 25% in principal amount of the bonds may declare the principal of all bonds, if not already due, together with all accrued and unpaid interest thereon, to be immediately due and payable. The Mortgage Trustee, upon request of the holders of a majority in principal amount of the outstanding bonds, shall waive such default and rescind any such declaration if such default is cured.

The Mortgage further provides that upon the occurrence of one or more completed defaults, the Mortgage Trustee and the Co-Trustee may proceed by such suits of law or in equity to foreclose the lien of the Mortgage or to enforce any other appropriate remedy as the Mortgage Trustee and the Co-Trustee, being advised by counsel, shall determine.

Holders of bonds have no right to enforce any remedy under the Mortgage unless the Mortgage Trustee and the Co-Trustee have first had a reasonable opportunity to do so following notice of default to the Mortgage Trustee and request by the holders of not less than 25% in principal amount of the bonds for action by the Mortgage Trustee and the Co-Trustee with offer of indemnity satisfactory to the Mortgage Trustee and the Co-Trustee against costs, expenses and liabilities that may be incurred thereby, but such provision does not impair the absolute right of any bondholder to enforce payment of the principal of and interest on such bondholder’s bonds when due.

Default and Notice Thereof to Bondholders

The Mortgage provides that the following shall constitute completed defaults:

•

default shall be made by us in the payment of any installment of interest on any of the bonds when due and such default shall continue for 60 days;

•

default shall be made by us in the payment of the principal of any of the bonds when due, whether at maturity or by declaration or otherwise;

•

default shall be made by us in the payment of any installment of interest on any prior lien bonds when due, and such default shall continue for 30 days after written notice given to us (following the expiration of the period of grace, if any, specified in the prior lien securing such prior lien bonds) by the Mortgage Trustee or to us and the Mortgage Trustee by the holders of not less than 5% in principal amount of the bonds;

•

default shall be made by us in the payment of the principal of any prior lien bonds when due, whether at maturity or by declaration or otherwise, and such default shall continue for 30 days after written notice to us by the Mortgage Trustee or to us and the Mortgage Trustee by the holders of not less than 5% in principal of the bonds;

•

bankruptcy, receivership or similar proceedings shall be initiated by us, or any judgment entered in such proceedings initiated against us shall not have been vacated, set aside or stayed within 45 days after the entry thereof; and

•

default shall be made in the observance or performance of any other of our covenants, conditions or agreements contained in the Mortgage or in the bonds or in any prior lien or prior lien bonds, and such default shall continue for 90 days after written notice to us and the Mortgage Trustee by the holders of not less than 25% in principal amount of the bonds.

Within 90 days after the occurrence of any default which is known to the Mortgage Trustee and the Co-Trustee, the Mortgage Trustee and the Co-Trustee shall give to the bondholders notice of such default unless it shall have been cured; except, in case of defaults in the payment of principal of or interest on the bonds, or in the payment of any sinking fund or purchase fund installment, if the Mortgage Trustee shall in good faith determine that the withholding of such notice is in the interests of the bondholders and the Co-Trustee shall in good faith determine that the withholding of such notice is in the interests of the bondholders.

TABLE OF CONTENTS

Certificates and Opinions

Officers’ certificates evidencing compliance with the covenants in the Mortgage relating to the payment of taxes and the maintenance of insurance on our properties subject to the lien of the Mortgage must be filed as exhibits to our certificate filed annually with the Mortgage Trustee. In connection with the taking of various actions by the Mortgage Trustee and the Co-Trustee, or the Mortgage Trustee upon our application, including the authentication and delivery of additional bonds, the release of property, the reduction or withdrawal of cash and other matters, the Mortgage requires that we furnish to the Mortgage Trustee orders, requests, resolutions, certificates of the officers, engineers, accountants and appraisers, and opinions of counsel and other documents, the particular documents to be furnished in each case being dependent upon the nature of the application.

TABLE OF CONTENTS

PLAN OF DISTRIBUTION

We may sell the Securities offered (a) through agents; (b) by underwriters or dealers; (c) directly to one or more purchasers; or (d) through a combination of any of these methods of sale.

In some cases we may also repurchase the Securities and reoffer them to the public by one or more of the methods described above.

This prospectus may be used in connection with any offering of securities through any of these methods or other methods described in the applicable prospectus supplement.

Any underwriter or agent involved in the offer and sale of the Securities will be named in the applicable prospectus supplement.

By Agents

Offered securities may be sold on a one time or a continuing basis by agents designated by the applicable registrant. The agents will use their reasonable efforts to solicit purchases for the period of their appointment under the terms of an agency agreement between the agents and the applicable issuer.

By Underwriters or Dealers

If underwriters are used in the sale, the underwriters may be designated by the applicable registrant or selected through a bidding process. The securities will be acquired by the underwriters for their own account. The underwriters may resell the Securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may sell the Securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. The obligations of the underwriters to purchase the Securities will be subject to certain conditions. The underwriters will be obligated to purchase all the Securities of the series offered if any of the securities are purchased. Any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time.

Only underwriters named in the applicable prospectus supplement are deemed to be underwriters in connection with the Securities offered hereby.

If dealers are utilized in the sale of the Securities, the applicable registrant will sell the Securities to the dealers as principals. The dealers may then resell the Securities to the public at varying prices to be determined by such dealers at the time of resale. The names of the dealers and the terms of the transaction will be set forth in the applicable prospectus supplement.

Direct Sales

We may also sell Securities directly to the public. In this case, no underwriters or agents would be involved.

General Information

We may authorize agents, underwriters or dealers to solicit offers by certain institutions to purchase Securities from us at the public offering price pursuant to delayed delivery contracts providing for payment and delivery on a later date or dates, all as described in the applicable prospectus supplement. Each delayed delivery contract will be for an amount not less than, and the aggregate amount of the Securities shall be not less nor more than, the respective amounts stated in the applicable prospectus supplement. Such institutions may include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions, and other institutions, but will in all cases be subject to our approval. The delayed delivery contracts will not be subject to any conditions except:

•

the purchase by an institution of the Securities covered by its delayed delivery contract shall not, at any time of delivery, be prohibited under the laws of any jurisdiction in the United States to which such delayed delivery contract is subject; and

TABLE OF CONTENTS

•

if the Securities are being sold to underwriters, we shall have sold to those underwriters the total amount of the Securities less the amount thereof covered by the delayed delivery contracts. The underwriters will not have any responsibility in respect of the validity or performance of the delayed delivery contracts.

Unless otherwise specified in the related prospectus supplement, each series of the Securities will be a new issue with no established trading market, other than the common stock. Any common stock sold pursuant to a prospectus supplement or issuable upon conversion of another offered Security will be listed on The Nasdaq Stock Market LLC, subject to official notice of issuance. We may elect to list any of the other securities on an exchange but are not obligated to do so. It is possible that one or more underwriters may make a market in a series of the Securities, but no underwriter will be obligated to do so and any underwriter may discontinue any market making at any time without notice. We cannot predict the activity of trading in, or liquidity of, our Securities.

In connection with sales by an agent or in an underwritten offering, the SEC rules permit the underwriters or agents to engage in transactions that stabilize the price of the Securities. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters or agents of a greater number of securities than they are required to purchase in an offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the Securities while an offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the underwriters have repurchased Securities sold by or for the account of that underwriter in stabilizing or short-covering transactions.

These activities by the underwriters may stabilize, maintain or otherwise affect the market price of the Securities. As a result, the price of the Securities may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected on an exchange or automated quotation system, if the Securities are listed on that exchange or admitted for trading on that automated quotation system, in the over-the-counter market or otherwise.

We may from time to time, without the consent of the existing Security holders, create and issue further Securities having the same terms and conditions as the Securities being offered hereby in all respects, except for issue date, issue price and if applicable, the first payment of interest or dividends therein or other terms as noted in the applicable prospectus supplement.
