We urge you to carefully read this prospectus supplement and the accompanying prospectus, which describe the terms of the offering of the notes, before you make your investment decision. This prospectus supplement, the accompanying prospectus and any related free writing prospectus required to be filed with the Securities and Exchange Commission, or the SEC, that we prepare or authorize contain and incorporate by reference information that you should consider when making your investment decision. We have not, and the underwriters have not, authorized anyone else to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We are not, and the underwriters are not, making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should not assume that the information appearing in this prospectus supplement and the accompanying prospectus is accurate as of any date other than the date on the front of those documents or that the information incorporated by reference is accurate as of any date other than the date that the document incorporated by reference was filed with the SEC.

It is expected that delivery of the notes will be made against payment therefor on or about the closing date specified on the cover page of this prospectus supplement, which will be the 3rd business day following the date of this prospectus supplement (this settlement cycle being referred to as “T+3”). Under Rule 15c6-1(a) of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of this prospectus supplement will be required, by virtue of the fact that the notes initially will settle in T+3, to specify alternative settlement arrangements to prevent a failed settlement and should consult their own advisors.

This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of the notes, this offering and certain other matters relating to us and our financial condition. The second part is the accompanying prospectus, which provides more general information about securities we may offer from time to time. Some of the information in the accompanying prospectus does not apply to this offering. You should read the entire prospectus supplement and the accompanying prospectus, including the documents incorporated by reference that are described under “Where You Can Find More Information” in this prospectus supplement.

This prospectus supplement, the accompanying prospectus, any related free writing prospectus required to be filed with the SEC and any written communication from us or the underwriters specifying the final terms of the offering that we prepare or authorize contain and incorporate by reference information that you should consider when making your investment decision. To the extent the information in this prospectus supplement differs from the information in the accompanying prospectus, you should rely on the information in this prospectus supplement. Neither we nor the underwriters or their affiliates and agents have authorized anyone to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. Neither we nor the underwriters or their affiliates and agents are making an offer of these securities in any jurisdiction where the offer is not permitted. The information in this prospectus supplement, the accompanying prospectus, the documents incorporated by reference herein or therein and any written communication from us specifying the final terms of the offering is only accurate as of the date of the respective document in which the information appears. Our business, financial condition, results of operations and prospects may have changed since those dates.

We are a regulated electric transmission and distribution utility company and a regulated gas distribution utility company with a service territory that covers the City of Baltimore and all or part of 10 counties in central Maryland. We are a public service company under the Public Utilities Article of the Maryland Annotated Code subject to regulation by the Maryland Public Service Commission, with respect to electric and gas distribution rates and service, the issuances of certain securities and certain other aspects of our operations. We are a public utility under the Federal Power Act subject to regulation by Federal Energy Regulatory Commission with respect to electric transmission rates and certain other aspects of our business and by the U.S. Department of Transportation as to pipeline safety and other areas of gas operations. Specific operations of ours are subject to the jurisdiction of various other federal, state, regional and local agencies. Additionally, we are also subject to North American Electric Reliability Corporation mandatory reliability standards.

Our electric service territory includes an area of approximately 2,300 square miles. Our gas service territory includes an area of approximately 3,050 square miles. We deliver electricity to approximately 1.3 million customers and natural gas to approximately 0.7 million customers.

We were incorporated in the State of Maryland in 1906. Our principal executive offices are located at 2 Center Plaza, 110 West Fayette Street, Baltimore, Maryland 21201, and our telephone number is (410) 234-5000.

We have provided the following summary financial information for your reference. We have derived the summary information presented here from the financial statements we have incorporated by reference into this prospectus supplement and the accompanying prospectus or previously filed with the SEC. You should read the summary information together with our historical consolidated financial statements and the related notes incorporated by reference in this prospectus supplement and the accompanying prospectus. See “Where You Can Find More Information.”

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, 2020 and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2021, 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. See “Where You Can Find More Information.”

We can give no assurances concerning 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. If markets for the notes do not develop, investors may be unable to resell the notes for an extended period of time, if at all. If markets for the notes do develop, they may not continue or it 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, secured or unsecured, 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.

We anticipate our net proceeds from the sale of the notes will be approximately $ after deducting the underwriting discount and estimated offering expenses. We intend to use the net proceeds we receive from the issuance and sale of the notes (i) to repay certain outstanding commercial paper obligations, (ii) to redeem $300 million aggregate principal amount outstanding of our 3.500% notes due November 15, 2021, and (iii) for general corporate purposes. As of June 3, 2021, we had approximately $124 million of outstanding commercial paper obligations, which had remaining maturities of less than 30 days and annual interest rates of 0.15%. If we do not use the net proceeds immediately, we may temporarily invest them in short-term, interest-bearing obligations.

The following table shows our consolidated capitalization and short-term borrowings as of March 31, 2021 and as adjusted to reflect the issuance of the notes and the use of the net proceeds of this offering as forth under “Use of Proceeds” above. This table is qualified in its entirety by, and should be considered in conjunction with, the more detailed information incorporated by reference or provided in this prospectus supplement or in the accompanying prospectus.

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.

We will issue $ of the % notes due 2031 under an indenture dated as of September 1, 2019, or the Indenture, which is a contract between us and the trustee, U.S. Bank National Association, or the Trustee, as it has been and may be further supplemented from time to time. The form of the Indenture is filed as an exhibit to the registration statement that contains the accompanying prospectus. Subject to the limitations described in this prospectus supplement and the accompanying prospectus, we may issue additional notes under the Indenture or under any other 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. An officer’s certificate will establish the terms of the notes under the Indenture.

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 any such transaction 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.

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. 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 and Short-Term Borrowings” in this prospectus supplement for information with respect to the long-term debt and short-term borrowings of us and our subsidiaries as of March 31, 2021.

We will pay interest on the notes at the fixed rate of % per annum, payable semi-annually on June 15 and December 15 of each year, beginning December 15, 2021. The notes will mature on June 15, 2031.

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. So long as all of the notes remain in book-entry only form, the record date for each interest payment date will be the close of business on the business day immediately preceding the applicable interest payment date. If any of the notes do not remain in book-entry only form, the record date for each interest payment date will be the close of business on the first calendar 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.

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 The Depository Trust Company, which we refer to as DTC, 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.

At any time prior to March 15, 2031 (i.e., three months prior to the maturity date of the notes), we may, at our option, redeem some or all of the notes, in each case upon at least 10 days’ and not more than 60 days’ notice, at a redemption price equal to the greater of:

At any time on or after March 15, 2031, we may redeem some or all of such notes upon at least 10 days’ and not more than 60 days’ notice, at our option, at a redemption price equal to 100% of the principal amount of the notes then outstanding to be redeemed plus accrued and unpaid interest on the principal amount being redeemed to the redemption date.

If at the time a redemption notice is given, the redemption moneys are not on deposit with the Trustee, then the redemption shall be subject to their receipt on or before the redemption date and such notice shall be of no effect unless such moneys are so received. Any 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.

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the series of notes being redeemed (assuming the notes matured on June 15, 2031), that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of the notes.

“Comparable Treasury Price” means, with respect to any redemption date, the average of the Reference Treasury Dealer Quotations for such redemption date.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by us.

“Reference Treasury Dealer” means each of (i) Barclays Capital Inc., Goldman Sachs & Co. LLC, and J.P. Morgan Securities LLC, and in each case their respective successors and affiliates, and (ii) one other primary U.S. Government securities dealer in the United States of America (each, a “Primary Treasury Dealer”) selected by us; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, or is unwilling or unable to serve in such role, we shall substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by us, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to us at 3:30 p.m. New York City time on the third Business Day preceding such redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to actual or interpolated maturity (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

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

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.

Except in cases of default where the Trustee has some special duties, 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 series of debt securities.

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

However, you are entitled at any time to bring a lawsuit for the payment of money due on the notes on or after their 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.

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

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

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.

A vote in favor by securityholders owning not less than 66-2/3% 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.

We may not merge or consolidate with any entity or sell substantially all of our assets as an entirety unless:

The Indenture provides that we can discharge and satisfy all of our obligations under any series of debt securities that are payable within one year, or under any series of debt securities that we deliver to the Trustee (and that have not already been cancelled), by depositing with the Trustee or any paying agent, enough funds to pay the principal and interest due or to become due on such debt securities until their maturity date.

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

We will issue each series of 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 (over 3.5 million issues of) U.S. and non-U.S. equity, corporate and municipal debt issues, and money market instruments (from over 100 countries) 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, or DTCC. DTCC is the holding company for DTC, National 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 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.

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 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.

The following is a summary of certain 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 provisions of 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, or 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 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 the notes that purchase the notes in this offering at their “issue price” (generally, the first price at which a substantial amount of the notes are sold for money to the public (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, including, but not limited to, certain 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, broker-dealers, dealers or traders in securities or currencies, real estate investment trusts, regulated investment companies, persons who mark their securities to market for federal income tax purposes, certain former citizens or residents of the United States subject to section 877 of the Code, part-year non-resident aliens, controlled foreign corporations, passive foreign investment companies and taxpayers subject to the alternative minimum tax. This summary also does not discuss notes held as part of a hedge, straddle, synthetic security, conversion transaction, or situations in which the “functional currency” of a United States Holder (as defined below) is not the United States dollar. Moreover, the effects of any applicable federal estate or gift, state, local or non-United States tax laws are not discussed. The following discussion assumes that the notes will be issued with no (or de minimis) original issue discount.

In the case of a beneficial owner of the notes that is classified as a partnership for United States federal income tax purposes, the tax treatment of the notes to a partner of the partnership generally will depend upon the tax status of the partner and the activities of the partner and the partnership. Persons who are partners of a partnership holding the notes should consult their own tax advisors.

The following discussion is for informational purposes only and is not a substitute for careful tax planning and advice. Investors considering the purchase, ownership, or disposition of the 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.

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 a series of the notes to be treated as CPDIs if, as of the issue date of such series of 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 all or part of 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:

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 regular method of accounting for United States federal income tax purposes.

Sale, exchange, redemption, retirement or other taxable disposition of the notes

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 (i) the amount realized upon the disposition and (ii) the United States Holder’s adjusted tax basis in the note. The amount realized will be equal to the sum of the amount of cash and the fair market value of any property received in exchange for the note (less any portion allocable to any accrued and unpaid interest, which will be taxed as ordinary interest income to the extent not previously so taxed). A United States Holder’s adjusted tax basis in a note generally will equal the cost of the note to such holder, reduced, as applicable, by any principal payments on the note received by such United States Holder. This gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if the United States Holder has held the note for more than one year. In general, long-term capital gains of a non-corporate United States Holder are taxed at lower rates than those applicable to ordinary income. 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.

An additional 3.8% tax is 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 State 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 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). A United States Holder that is an individual, estate or trust, should consult a tax advisor regarding the applicability of the Medicare contribution tax to its income and gains in respect of its investment in the notes.

In general, information reporting requirements apply with respect to payments to certain non-corporate United States Holders of principal, premium, if any, and interest on a note, and payments to such holders of the proceeds of the sale, exchange, redemption, retirement or other taxable disposition of a note. The payor (which may be us or an intermediate payor) will be required to impose backup withholding tax, currently at a rate of 24%, if (i) the payee fails to furnish a taxpayer identification number, or TIN, to the payor or to establish an exemption from backup withholding tax, (ii) the IRS notifies the payor that the TIN furnished by the payee is incorrect, (iii) there has been a notified payee underreporting described in section 3406(c) of the Code or (iv) 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. United States 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 such holder’s United States federal income tax liability, if any, and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

The following is a summary of the material United States federal income tax consequences that will apply to a non-United States Holder. As used herein, the term “non-United States Holder” means a beneficial owner of notes that is a nonresident alien individual, a foreign corporation, a foreign estate or trust (other than a grantor trust), in each case, for United States federal income tax purposes and that is not a United States Holder. Specific rules may apply to non-United States Holders that are subject to special treatment under the Code, including controlled foreign corporations, passive foreign investment companies, certain United States expatriates and foreign persons eligible for benefits under an applicable income tax treaty with the United States. Such non-United States Holders should consult their tax advisors to determine the United States federal, state, local and other tax consequences that may be relevant to them.

Subject to the discussions below under “Effectively connected income,” “Information reporting and backup withholding,” and “FATCA compliance,” 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 exception” provided that (i) 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, (ii) the non-United States Holder is not a controlled foreign corporation related to us, actually or constructively, through stock ownership, (iii) 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 (iv) either (a) the non-United States Holder provides to us or our paying agent the required certifications set forth under section 871(h)

and section 881(c) of the Code, as described in the following paragraph, 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 it has received such required certification from the non-United States Holder or a qualifying intermediary and furnishes a copy to us or our agent.

To qualify for the exemption from withholding tax with respect to the notes, a non-United States Holder generally will be required to provide a statement signed under penalty of perjury that certifies that such non-United States Holder is the beneficial owner of the note and is not a United States person as defined in the Code and provides such non-United States Holder’s name and address. This statement generally will be made on an IRS Form W-8BEN or IRS Form W-8BEN-E or a substantially similar substitute form. A non-United States Holder must further inform the recipient of such form of any change in the information on the statement within 30 days of such change. Special procedures apply in the case of a payment to a foreign partnership or to certain foreign trusts.

A non-United States Holder that does not qualify for exemption from withholding as described above generally will be subject to withholding of United States federal income tax at a rate of 30% on payment of interest on the notes. A non-United States Holder may be entitled to the benefits of an income tax treaty under which interest on the notes is subject to an exemption from, or a reduced rate of, United States withholding tax. In general, a non-United States Holder is only eligible for an exemption or reduced rate if it furnishes a properly completed and executed IRS Form W-8BEN or IRS Form W-8BEN-E or a substantially similar substitute form and any applicable attachments claiming the exemption from, or reduction in, withholding tax under the tax treaty and complies with any other applicable procedures.

Sale, exchange, redemption, retirement or other taxable disposition of the notes

Subject to the discussions below under “Effectively connected income,” “Information reporting and backup withholding,” and “FATCA compliance,” a non-United States Holder generally will not be subject to United States federal income tax on gain realized on the sale, exchange, redemption, retirement or other taxable disposition of notes unless the non-United States Holder is a nonresident alien individual who is present in the United States for 183 or more days in the taxable year of the disposition and certain other conditions are met. If a non-United States Holder is an individual who is present in the United States for 183 days or more during the taxable year of the sale, exchange, redemption, retirement or other taxable disposition of a note, then such non-United States Holder generally will be subject to United States federal income tax at a flat rate of 30% (unless a lower applicable treaty rate applies) on any such realized gain (which gain shall be calculated in the same manner discussed above under “United States Holders—Sale, exchange, redemption, retirement or other taxable disposition of the notes”), which may be offset by losses allocable to sources within the United States.

If a non-United Stated Holder is engaged in the conduct of a trade or business in the United States, and if interest on the notes or gain realized on a taxable disposition of notes is effectively connected with the conduct of such trade or business (and, generally, if an income tax treaty applies, is attributable to a United States permanent establishment or fixed base maintained by the non-United States Holder), the non-United States Holder generally will be exempt from the withholding tax discussed in the preceding paragraphs (provided that the non-United States Holder provides a properly completed and executed IRS Form W-8ECI or substantially similar substitute form). However, the non-United States Holder generally will be subject to United States federal income tax on such income or gain on a net income basis in the same manner as if it were a United States Holder (unless an applicable treaty provides otherwise). In addition, if such a non-United States Holder is a corporation, such non-United States Holder may also be subject to a branch profits tax equal to 30% (or such lower rate provided by an applicable income tax treaty) of its earnings and profits for the taxable year that are effectively connected with its conduct of a trade or business in the United States, subject to certain adjustments.

The amount of interest paid to certain non-United States Holders on the notes and the tax withheld (if any) with respect to such interest, will be reported annually to the IRS, even if such non-United States Holders are exempt from the 30% withholding tax described above. Copies of the information returns reporting such interest and withholding may also be made available to the tax authorities in the country in which the non-United States Holder is a resident under the provisions of an applicable income tax treaty or information exchange agreement.

A non-United States Holder will be subject to backup withholding on interest paid to such non-United States Holder unless such non-United States Holder certifies under penalties of perjury that it is not a United States person as defined under the Code (and certain other conditions are met) or otherwise establishes an exemption from backup withholding. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a non-United States Holder’s United States federal income tax liability, provided the required information is timely furnished to the IRS.

Information reporting and, if applicable, backup withholding generally will apply to the proceeds of a disposition of notes by a non-United States Holder effected within the United States or through certain United States-related financing intermediaries, unless the non-United States Holder certifies under penalties of perjury that it is not a United States person (and certain other conditions are met) or otherwise establishes an exemption from such requirements. Under current law, the backup withholding rate is 24%.

Sections 1471 through 1474 of the Code and related Treasury guidance, collectively referred to as FATCA, generally impose United States federal withholding tax at a rate of 30% on payments to certain foreign entities of United States-source interest income (including interest paid on the notes), unless various information reporting and diligence requirements are satisfied. This tax would generally apply in the case of notes held through foreign financial institutions that do not satisfy such requirements. Such withholding will not apply if such foreign financial institution (i)(a) enters into, and is in compliance with, an agreement with the United States government to withhold on certain payments and to collect and provide to the IRS substantial information regarding United States account holders of such institution (which 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) resides in a jurisdiction with which the United States has entered into an intergovernmental agreement to implement FATCA and (ii) provides the withholding agent with a certification that such foreign financial institution is eligible to receive the applicable payment free of FATCA withholding. No additional amounts will be payable by us on account of any withholding obligation that is imposed with respect to payments on a note as a result of the failure of any beneficial owner of a note, or any intermediary through which it directly or indirectly owns such note, to comply with the requirements of FATCA (or any other withholding tax provisions). Foreign entities located in jurisdictions that have entered into an intergovernmental agreement with the United States governing FATCA may be subject to modified rules. Under proposed Treasury regulations, the FATCA withholding tax will not apply to the gross proceeds from the sale or other disposition of assets such as the notes. These proposed regulations state that they be relied upon until final regulations are issued. Non-United States Holders should consult their tax advisors regarding the possible implications of FATCA on their ownership and disposition of the notes.

We are selling the notes to the underwriters named in the table below pursuant to an underwriting agreement dated the date hereof, and each of the underwriters have severally agreed to purchase from us the respective principal amount of notes set forth opposite its name below:

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.

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

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 cannot give any assurance as to the maintenance of the trading market for, or the liquidity of, the notes, the ability of the holders to sell their notes or the price at which holders will be able to sell their notes.

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.

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.

We have agreed to indemnify the several underwriters against certain civil liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute with respect to payments which the several 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 $1,000,000.

The underwriters and their affiliates are full service financial institutions engaged in various activities. From time to time, in the ordinary course of business, the underwriters and their 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. In particular, the underwriters or their affiliates may hold our outstanding 3.500% notes due November 15, 2021 or commercial paper obligations issued by us, which may be repaid with a portion of the net proceeds received by us from the sale of the notes. See “Use of Proceeds.”

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 has 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 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 European Economic Area (“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 Regulation (EU) 2017/1129 (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.

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 United Kingdom (“UK”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (“EUWA”); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (“FSMA”) and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the EUWA. Consequently, no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

Words such as “believes,” “anticipates,” “expects,” “intends,” “plans,” “predicts” and “estimates” and similar expressions 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.

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.

Investing in the Securities involves various risks.

Except as otherwise indicated in the applicable prospectus supplement, each registrant expects to use the net proceeds from the sale of the Securities for general corporate purposes, including to discharge or refund (by redemption, by purchase on the open market, by purchase in private transactions, by tender offer or otherwise) outstanding long-term debt. Each registrant will describe in the applicable prospectus supplement any specific allocation of the proceeds to a particular purpose that the registrant has made at the date of that prospectus supplement. Please refer to our annual and quarterly reports incorporated by reference into this prospectus and any prospectus supplement for information concerning each registrant’s outstanding long-term debt. See “Where You Can Find More Information.

Each time one of the registrants sells securities, it will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus. You should read both this prospectus and any prospectus supplement together with additional information described under “Where You Can Find More Information.”

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.

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.

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.

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

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:

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 New York Stock Exchange, 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. Additional Securities issued in this manner will be consolidated with, and will form a single series with, the previously outstanding securities.

Underwriters, dealers and agents that participate in the distribution of the Securities may be underwriters as defined in the Securities Act of 1933, and any discounts or commissions received by them from us and any profit on the resale of the Securities by them may be treated as underwriting discounts and commissions under the Securities Act.

We may have agreements with the underwriters, dealers and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act of 1933, or to contribute with respect to payments which the underwriters, dealers or agents may be required to make.

Underwriters, dealers and agents may engage in transactions with, or perform services for, us or our subsidiaries or affiliates in the ordinary course of their businesses.

Ballard Spahr LLP, Philadelphia, Pennsylvania, will render an opinion as to the validity of the Securities for us.

Winston & Strawn LLP, Chicago, Illinois, will render an opinion as to the validity of the Securities for any underwriters, dealers, purchasers or agents. Winston & Strawn LLP provides legal services to Exelon and its subsidiaries from time to time.
