ALTERNATIVE SETTLEMENT DATE

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 one business day, 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.

The accompanying prospectus also includes information about Exelon and its affiliate, PECO Energy Company, or PECO, and their securities that does not apply to us or the notes. The notes are solely our obligations and not obligations of Exelon or its other affiliates.

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.

SUMMARY FINANCIAL INFORMATION

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" in this prospectus supplement.

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. See "Where You Can Find More Information" in this prospectus supplement.

There may be no public market for the notes, and general market conditions may adversely affect the market prices of the notes.

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. 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 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 develop, they may not continue or such markets may not be sufficiently liquid to allow holders to resell 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 the 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 the notes and the risk that one or more of the credit ratings of the notes are lowered or withdrawn.

USE OF PROCEEDS

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 retire $350 million of our 2.400% senior notes due August 15, 2026 and (ii) for general corporate purposes. If we do not use the net proceeds of the notes immediately, we may temporarily invest them in short-term, interest-bearing obligations.

CAPITALIZATION

The following table shows our consolidated capitalization as of March 31, 2026 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.

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 $      of the 2033 notes and $      of the 2056 notes under an indenture dated as of September 1, 2019 (the "Indenture"), which is a contract between us and the successor trustee, U.S. Bank Trust Company, National Association (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.

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. 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 March 31, 2026.

Interest Rate and Maturity

We will pay interest at the fixed rate of    % per annum for the 2033 notes and    % per annum for the 2056 notes, in each case payable semi-annually on           and           of each year, beginning           , 2026. The 2033 notes will mature on           , 2033 and the 2056 notes will mature on           , 2056.

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.

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 The Depository Trust Company ("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.

Optional Redemption

At any time prior to (i)           , 2033 (two months prior to the maturity date of the 2033 notes) (the "2033 notes Par Call Date") and (ii)           , 2055 (six months prior to the maturity date of the 2056 notes) (the "2056 notes Par Call Date"), we may redeem 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 2033 notes Par Call Date, in the case of the 2033 notes, or the 2056 notes Par Call Date, in the case of the 2056 notes) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus      basis points, in the case of the 2033 notes or      basis points, in the case of the 2056 notes, less (b) interest accrued to the date of redemption; and

​

•

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

​

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

On or after the 2033 notes Par Call Date, in the case of the 2033 notes, or on or after the 2056 notes Par Call Date, in the case of the 2056 notes, 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.

"Par Call Date" means (i) the 2033 notes Par Call Date, in the case of the 2033 notes, or (ii) the 2056 notes Par Call Date, in the case of the 2056 notes.

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"); (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 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 or any successor designation or publication 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. For the avoidance of doubt, the Trustee shall have no duty to calculate the redemption price nor shall it have any duty to review or verify our calculations of the redemption price.

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, selection of the notes for redemption will be made pro rata, by lot or by such other method as the Trustee deems appropriate and fair in accordance with the applicable depositary procedures and any applicable stock exchange rules. No notes of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note. For so long as the notes are held by DTC (or another depositary), the redemption of the notes 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.

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.

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 interest 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 60 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); or

​

•

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

​

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:

•

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

​

•

the holders of 25% of the principal amount of all outstanding notes 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 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.

Supplemental Indentures

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

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;

​

•

reducing the interest rate, changing the method of establishing 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; 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 66-2/3% of all Holders to Approve

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.

Consolidation, Merger or Sale

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

•

we are the continuing entity, or the successor entity 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 corporation, 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

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.

Governing Law

The Indenture and the notes are 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 Securities Exchange Act of 1934, as amended (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 ("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 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 continuing, 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.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

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 (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 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 is 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, accrual-method taxpayers subject to section 451(b) of the Code, 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. It is expected, and 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.

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 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 of notes, 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.

United States Holders

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 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 or 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 (i) 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 (ii) the trust was in existence on August 20, 1996 and has made a valid election under applicable Treasury regulations to continue to be treated as a United States person.

​

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 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.

Medicare tax

An additional 3.8% tax is imposed on certain United States Holders that 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 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.

Information reporting and backup withholding

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.

Non-United States Holders

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 a foreign 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 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.

Payment of interest

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% 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 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, (iii) the interest in the notes is not effectively connected with the non-United States Holder's conduct of a trade or business in the United States, 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.

Effectively connected income

If a non-United States 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.

Information reporting and backup withholding

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 the 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.

FATCA compliance

The Foreign Account Tax Compliance Act (commonly known as "FATCA") imposes a reporting regime and a 30% withholding tax with respect to certain payments to any non-United States financial institution (a "foreign financial institution," or "FFI" ​(as defined by FATCA)) unless such foreign financial institution (i) enters into an agreement with the Department of the Treasury to collect and provide substantial information regarding its United States account holders, as well as certain account holders that are foreign entities with United States owners, (ii) satisfies the requirements of an intergovernmental agreement entered into by such institution's country of residence and the United States, or (iii) qualifies for an exemption. These withholding requirements generally currently apply to payments of interest on the notes. Under proposed Treasury Regulations, this withholding tax will not apply to the gross proceeds from the sale or other disposition of the notes. The preamble to these proposed Treasury Regulations indicates that taxpayers may rely on them pending their finalization.

If an amount in respect of FATCA withholding were to be deducted or withheld from interest, principal or other payments made in respect of the notes, neither we nor any paying agent nor any other person would be required to pay additional amounts as a result of the deduction or withholding. As a result, holders may receive less interest or principal than expected. Non-United States Holders should consult with their own tax advisors regarding the possible implications of FATCA on their ownership and disposition of 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 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 (CONFLICTS OF INTEREST)

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, and not jointly, 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 the 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 $      .

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 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. In addition, U.S. Bancorp Investments, Inc., one of the underwriters, is an affiliate of the Trustee under the indenture governing the notes. See "Use of Proceeds" in this prospectus supplement.

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.

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

​

•

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. We may elect to list any 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.
