securities that we may offer from time to time, some of which may not apply to the notes we are offering hereby. Generally, when we refer to the
prospectus, we are referring to both this prospectus supplement and the accompanying base prospectus. If the description of the notes varies between this
prospectus supplement and the accompanying base prospectus, you should rely on the information in this prospectus supplement. References in this
prospectus to "Edison International," "we," "us," and "our" mean Edison International on a stand-alone basis, not consolidated with its subsidiaries.
FORWARD-LOOKING STATEMENTS
This prospectus and the documents they incorporate by reference contain "forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Forward-looking statements reflect our current expectations and projections about future events based on our knowledge of

this prospectus and elsewhere, the words "expects," "believes," "anticipates," "estimates," "projects," "intends," "plans," "probable," "may," "will,"
"could," "would," "should," and variations of such words and similar expressions, or discussions of strategy or of plans, are intended to identify forward-
looking statements. Such statements necessarily involve risks and uncertainties that could cause actual results to differ materially from those anticipated.
Some of the risks, uncertainties and other important factors that could cause results to differ from those currently expected, or that otherwise could impact
us and our subsidiaries, include, but are not limited to:

including costs related to the San Onofre Nuclear Generating Station ("San Onofre"), uninsured wildfire-related exposure, and spending on
grid modernization;

such as wildfires;

·
risks associated with cost allocation, resulting in higher rates for utility bundled service customers because of possible customer bypass or

departure due to Community Choice Aggregators, which are cities, counties, and certain other public agencies with the authority to generate
and/or purchase electricity for their local residents and businesses;

·
risks inherent in SCE's transmission and distribution infrastructure investment program, including those related to project site identification,

public opposition, environmental mitigation, construction,

permitting, power curtailment costs (payments due under power contracts in the event there is insufficient transmission to enable acceptance of

power delivery), changes in the California Independent Systems Operator's transmission plans, and governmental approvals;

business and customer data;

·
our ability to develop competitive businesses, manage new business risks, and recover and earn a return on our investment in newly developed

or acquired businesses;

·
changes in tax laws and regulations, at both the state and federal levels, or changes in the application of those laws; that could affect recorded

deferred tax assets and liabilities and effective tax rates;

·

rules applicable to each market adopted by the North American Electric Reliability Corporation, Regional Transmission Organizations, and
similar regulatory bodies in adjoining regions;

·
availability and creditworthiness of counterparties and the resulting effects on liquidity in the power and fuel markets and/or the ability of

counterparties to pay amounts owed in excess of collateral provided in support of their obligations;

·
cost and availability of labor, equipment and materials;

·
potential for penalties or disallowances for non-compliance with applicable laws and regulations;

·
cost of fuel for generating facilities and related transportation, which could be impaired by, among other things, disruption of natural gas

storage facilities, to the extent not recovered through regulated rate cost escalation provisions or balancing accounts; and

·
disruption of natural gas supply due to unavailability of storage facilities, which could lead to electricity service interruptions.
Additional information about risks and uncertainties that could cause results to differ from those currently expected or that otherwise could impact us,
including more detail about the factors described above, is included in our Annual Report on Form 10-K for the year ended December 31, 2017 and our

RISK FACTORS
Your decision whether or not to purchase any of the notes will involve some degree of risk. You should be aware of and carefully consider the
following risk factors and the risk factors included in our Annual Report on Form 10-K for the year ended December 31, 2017 (which is incorporated by
reference in this prospectus supplement and the related base prospectus). New risks may emerge at any time, and we cannot predict such risks or estimate
the extent to which they may affect our financial performance. You should also read and consider all of the other information provided or incorporated by
reference in this prospectus supplement and the related base prospectus before deciding whether or not to purchase any of the notes. See "Forward-
Looking Statements" in this prospectus supplement and "Where You Can Find More Information" in the base prospectus.
You may be unable to sell your notes if a trading market for the notes does not develop.
The notes will be a new series of securities for which there is currently no established trading market, and none may develop. We do not intend to
apply for listing of the notes on any securities exchange or for quotation on any automated dealer quotation system. The liquidity of any market for the
notes will depend on the number of holders of the notes, the interest of securities dealers in making a market in the notes, and other factors. Accordingly,
https://www.sec.gov/Archives/edgar/data/827052/000119312518077077/d523778d424b5.htm[3/9/2018 4:32:29 PM]

Final Prospectus Supplement
we cannot assure you as to the development or liquidity of any market for the notes. If an active trading market does not develop, the market price and
liquidity of the notes may be adversely affected. If the notes are traded, they may trade at a discount from their initial offering price depending upon
prevailing interest rates, the market for similar securities, general economic conditions, our performance and business prospects, and certain other factors.
The notes are our obligations and not obligations of our subsidiaries and will be effectively subordinated to the claims of the subsidiaries'
creditors.
The notes are our obligations exclusively and not obligations of our subsidiaries. Because we are a holding company, our obligations under the notes
will be structurally subordinated to all existing and future liabilities and preferred equity of our subsidiaries. Therefore, our creditors, including holders of
the notes, will not have a direct right to participate in the assets of any subsidiary upon the liquidation or reorganization of the subsidiary. Instead, our
creditors will participate in those assets only to the extent that we receive a distribution from the subsidiary on account of any claim or interest that we have
against or in the subsidiary. At December 31, 2017, our subsidiaries had total consolidated liabilities of approximately $36.5 billion and preferred equity
outstanding with a total liquidation value of approximately $2.2 billion.
We may be unable to meet our ongoing and future financial obligations if our subsidiaries are unable to pay dividends to us.
Our ability to meet our financial obligations is primarily dependent on the earnings and cash flows of our subsidiaries and their ability to pay
dividends, make other distributions or repay funds owed from time to time to us. Prior to funding Edison International, our subsidiaries have financial and
regulatory obligations that must be satisfied, including, among others, debt service and preferred stock dividends. The CPUC also regulates SCE's capital
structure and limits the dividends it may pay to us. In addition, the indenture under which the notes will be issued does not limit our ability, or the ability of
our subsidiaries, to pledge shares of stock as security for other indebtedness.

S-4
Table of Contents
USE OF PROCEEDS
We intend to use approximately $500 million of the net proceeds from the offering of the notes to repay a borrowing under our term loan agreement,
and the remainder for general corporate purposes. The term loan borrowing has a variable interest rate based on the London Interbank Offered Rate plus 60
basis points. Certain lenders under the term loan agreement are affiliates of certain underwriters of this offering. These lenders will receive a portion of the
net proceeds we receive from the offering of the notes based on the amount of the loans they have extended under the term loan agreement. As a result, any
such underwriters or their respective affiliates are expected to receive a portion of the proceeds of this offering.

S-5
Table of Contents
CERTAIN TERMS OF THE NOTES
The notes will be a series of our debt securities issued under an indenture dated as of September 10, 2010 between Edison International, as issuer,
and The Bank of New York Mellon Trust Company, N.A., as trustee.
The summary of selected provisions of the notes and the indenture referred to below supplements, and to the extent inconsistent supersedes and
replaces, the description of the general terms and provisions of the debt securities and the indenture contained in the accompanying base prospectus. This
summary is not complete and is qualified by reference to provisions of the notes and the indenture. Forms of the notes and the indenture have been or will
be filed with the Securities and Exchange Commission and you may obtain copies as described under "Where You Can Find More Information" in the
accompanying base prospectus.
Interest Rate and Maturity
The notes will bear interest at the rate of 4.125% per year. Interest on the notes will be payable semi-annually in arrears on March 15 and
September 15 of each year, beginning on September 15, 2018, to the holders of record at the close of business on the immediately preceding March 1 and
September 1, respectively. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months; provided that the amount of
interest payable for any period shorter or longer than a full interest period will be computed on the basis of a 360-day year consisting of twelve 30-day
months and the actual number of days elapsed in the period using 30-day months.
The notes will mature on March 15, 2028. The notes are subject to earlier redemption at our option as described under "--Optional Redemption."
https://www.sec.gov/Archives/edgar/data/827052/000119312518077077/d523778d424b5.htm[3/9/2018 4:32:29 PM]

Final Prospectus Supplement
If any interest payment date, redemption date or the maturity date of the notes is not a business day in any place of payment, then payment of the
principal, premium, if any, and interest may be made on the next business day in that place of payment. In that case, no interest will accrue on the amount
payable for the period from and after the applicable interest payment date, redemption date or maturity date, as the case may be. The regular record date for
all payments of interest on the notes will be the first day of the month in which payment is to be made, whether or not such day is a business day.
We will pay interest on, principal of, and any premium on, the notes at stated maturity, upon redemption or otherwise, as described under "--Book-
Entry, Delivery and Form." The notes initially will be issued in book-entry form and represented by global securities deposited with, or on behalf of, The
Depository Trust Company, as Depositary, and registered in the name of Cede & Co., its nominee. This means that you will not be entitled to receive a
certificate for the notes that you purchase except in limited circumstances. If any of the notes are issued in certificated form they will be issued only in
fully registered form without coupons, in denominations of $1,000 and integral multiples of $1,000.
Ranking
The notes will be our unsecured senior debt obligations and will rank on a parity in right of payment with all of our other unsecured and
unsubordinated indebtedness. The notes are our obligations exclusively, and are not the obligations of any of our subsidiaries. Because we conduct our
operations primarily through our subsidiaries and substantially all of our consolidated assets are held by our subsidiaries, the notes will be effectively
subordinated to all existing and future liabilities (including indebtedness) and preferred equity of our subsidiaries. At December 31, 2017, our subsidiaries
had total consolidated liabilities of approximately $36.5 billion, and preferred equity outstanding with a total liquidation value of approximately
$2.2 billion. See "Description of the Debt Securities--Ranking--Holding Company Structure" in the accompanying base prospectus.

S-6
Table of Contents
Optional Redemption
We will be entitled to redeem the notes at our option as described below. You will not be permitted to require us to redeem or repurchase the notes
at your option.
All or a portion of the notes may be redeemed at our option at any time or from time to time. The redemption price for the notes to be redeemed on
any redemption date prior to December 15, 2027 will be equal to the greater of the following amounts:

·
100% of principal amount; or

·
the sum of the present values of the remaining scheduled payments of principal and interest, assuming for such purpose that the notes mature
on December 15, 2027, on the notes being redeemed on that redemption date (not including any portion of any payments of interest accrued to

the redemption date) discounted to the redemption date on a semi-annual basis at the Adjusted Treasury Rate (as defined below) plus 20 basis
points, as determined by the Independent Investment Banker (as defined below),
plus, in each case, accrued and unpaid interest on the notes to be redeemed to but excluding the redemption date. The redemption price will be calculated
by us on the basis of a 360-day year consisting of twelve 30-day months.
The redemption price for the notes to be redeemed on any redemption date on or after December 15, 2027 will be equal to 100% of the principal
amount of the notes being redeemed plus accrued and unpaid interest thereon to but excluding the redemption date.
Notwithstanding the foregoing, installments of interest on notes that are due and payable on interest payment dates falling on or prior to a redemption
date will be payable on the interest payment date to the registered holders as of the close of business on the relevant record date according to the notes and
the indenture.
"Adjusted Treasury Rate" means, for any date fixed for redemption, the rate per year equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for the date fixed for redemption.
"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 notes to be redeemed (assuming for such purpose that the notes mature on
December 15, 2027) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate
debt securities of comparable maturity to the remaining term of the notes to be redeemed (assuming for such purpose that the notes mature on
December 15, 2027).
"Comparable Treasury Price" means, for any date fixed for redemption, the average of the Reference Treasury Dealer Quotations for the date fixed
for redemption, or if only one Reference Treasury Dealer quotation is received, such quotation.
"Independent Investment Banker" means Wells Fargo Securities, LLC or its successor or, if such firm or its successor, as applicable, is unwilling or
https://www.sec.gov/Archives/edgar/data/827052/000119312518077077/d523778d424b5.htm[3/9/2018 4:32:29 PM]

Final Prospectus Supplement
unable to select the Comparable Treasury Issue, one of the remaining Reference Treasury Dealers appointed by us.
"Reference Treasury Dealer" means each of (1) Barclays Capital Inc., J.P. Morgan Securities LLC, and Wells Fargo Securities, LLC , and any other
primary U.S. Government securities dealer in the United States of America (a "Primary Treasury Dealer") designated by, and not affiliated with, any of the
foregoing or their successors, provided, however, that if any of the foregoing, or any of their designees, ceases to be a Primary Treasury Dealer, we will
appoint another Primary Treasury Dealer as a substitute, and (2) any other Primary Treasury Dealer selected by us.

S-7
Table of Contents
"Reference Treasury Dealer Quotations" means, for each Reference Treasury Dealer and any date fixed for redemption, the average, as determined
by the Independent Investment Banker, 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 the Independent Investment Banker by the Reference Treasury Dealer at 5:00 p.m. New York City time on the third
business day preceding the date fixed for redemption.
We will provide notice of any redemption at least 30 days but not more than 60 days before the redemption date to the registered holders of the notes
to be redeemed. We may make any redemption conditional upon the receipt by the paying agent, on or prior to the date fixed for redemption, of money
sufficient to pay the redemption price. If the paying agent has not received the money by the date fixed for redemption, we will not be required to redeem
the debt securities. See "Description of the Debt Securities--Redemption" in the accompanying base prospectus.
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.
No Sinking Fund
There will be no provisions for any sinking funds for the notes.
Other
We may, from time to time, without notice to or the consent of the holders of the notes, increase the principal amount of the notes under the indenture
and issue such increased principal amount (or any portion thereof), in which case any additional notes so issued shall have the same form and terms (other
than the date of issuance, public offering price, and, under certain circumstances, the date from which interest thereon shall begin to accrue and the first
interest payment date), and shall carry the same right to receive accrued and unpaid interest as the notes previously issued, and such additional notes shall
form a single series with the notes offered by this prospectus supplement, provided that such additional notes shall be fungible with the notes offered by
this prospectus supplement for United States federal income tax purposes.
Book-Entry, Delivery, and Form
The notes will be represented by one or more permanent global notes in definitive, fully registered form without interest coupons. Upon issuance, the
notes will be deposited with The Bank of New York Mellon Trust Company, N.A., as trustee, as custodian for The Depository Trust Company in New
York, New York (which we refer to as "DTC"), and registered in the name of DTC or its nominee.
Ownership of beneficial interests in a global note will be limited to persons who have accounts with DTC, which we refer to as "participants," or
persons who hold interests through participants. Ownership of beneficial interests in a global note will be shown on, and the transfer of that ownership will
be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect
to interests of persons other than participants).
You may elect to hold interests in a global note either in the United States through DTC or outside the United States through Clearstream Banking,
société anonyme ("Clearstream"), or Euroclear Bank, S.A./N.V., or its successor, as operator of the Euroclear System ("Euroclear"), if you are a participant
of such system, or indirectly through organizations that are participants in such systems. Interests held through Clearstream and Euroclear will be recorded
on DTC's books as being held by the U.S. depositary for each of Clearstream and Euroclear, which U.S. depositaries will in turn hold interests on behalf of
their participants' customers' securities accounts.

S-8
Table of Contents
So long as DTC, or its nominee, is the registered owner or holder of any of the notes, DTC or that nominee, as the case may be, will be considered
https://www.sec.gov/Archives/edgar/data/827052/000119312518077077/d523778d424b5.htm[3/9/2018 4:32:29 PM]

Final Prospectus Supplement
the sole owner or holder of such notes represented by the global note for all purposes under the note indenture and the notes. No beneficial owner of an
interest in a global note will be able to transfer such interest except in accordance with DTC's applicable procedures, in addition to those provided for
under the note indenture.
Payments of the principal of, and interest on, a global note will be made to DTC or its nominee, as the case may be, as the registered owner thereof.
None of the trustee, any paying agent, or we will have any responsibility or liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in a global note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.
We expect that DTC or its nominee, upon receipt of any payment of principal or interest in respect of a global note, will credit participants' accounts
with payments in amounts proportionate to their respective beneficial interests in the principal amount of such global note as shown on the records of DTC
or its nominee. We also expect that payments by participants to owners of beneficial interests in such global note held through such participants will be
governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of
nominees for such customers. Such payments will be the responsibility of such participants.
We expect that transfers between participants in DTC will be effected in the ordinary way in accordance with DTC rules and procedures and will be
settled in same-day funds. Secondary market trading between Clearstream participants and/or Euroclear system participants will occur in the ordinary way
in accordance with the applicable rules and operating procedures of Clearstream and the Euroclear system, as applicable.
We expect that DTC will take any action permitted to be taken by a holder of notes only at the direction of one or more participants to whose account
the DTC interests in a global note is credited and only in respect of such portion of the aggregate principal amount of notes as to which such participant or
participants has or have given such direction.
A global note is exchangeable for definitive notes in registered certificate form if:

·
DTC (i) notifies us that it is unwilling or unable to continue as depositary for the global notes, and we fail to appoint a successor depositary, or

(ii) has ceased to be a clearing agency registered under the Securities Exchange Act of 1934, as amended; or

·
at our option, we notify the trustee in writing that we have elected to cause the issuance of the certificated securities.
In all cases, certificated securities delivered in exchange for any global note or beneficial interests in global notes will be registered in the names,
and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures). Certificated
securities may be presented for registration, transfer and exchange at The Bank of New York Mellon Trust Company, N.A., Chicago, Illinois, or the office
or agency designated for such purpose.
DTC has advised us that: DTC is a limited purpose trust company organized under the laws of the State of New York, a "banking organization"
within the meaning of New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the Uniform
Commercial Code and a "Clearing Agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities
for its participants and facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes in
accounts of its participants, thereby eliminating the need for physical movement of certificates. Indirect access to the DTC system is available to others
such as banks, brokers, dealers and trust companies and certain other organizations that clear through or maintain a custodial relationship with a participant,
either directly or indirectly, whom we refer to as indirect participants.

Although DTC is expected to follow the foregoing procedures in order to facilitate transfers of interests in a global note among participants of DTC,
they are under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. None of the trustee,
the paying agent, nor we will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations
under the rules and procedures governing their operations.
Settlement and Payment
We will make payments in respect of the notes represented by the global notes (including principal, interest and premium, if any) by wire transfer of
immediately available funds to the accounts specified by the global noteholder. We will make all payments of principal, interest and premium with respect
to certificated securities by wire transfer of immediately available funds to the accounts specified by the holders thereof or, if no account is specified, by
mailing a check to that holder's registered address. The exchange notes represented by the global notes are expected to trade in DTC's Same Day Funds
Settlement System, and any permitted secondary market trading activity in the notes will, therefore, be required by DTC to be settled in immediately
available funds. We expect that secondary trading in any certificated securities will also be settled in immediately available funds.

Final Prospectus Supplement
Cross-market transfers between persons holding directly or indirectly through DTC on the one hand, and directly or indirectly through Clearstream
participants or Euroclear system participants on the other, will be effected through DTC in accordance with DTC 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 (European
time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S.
depositary to take action to effect final settlement on its behalf by delivering or receiving securities in DTC, and making or receiving payment in
accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream participants and Euroclear system participants may not
deliver instructions directly to their respective U.S. depositaries.
Because of time-zone differences, credits of notes received in Clearstream or the Euroclear system 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 in such notes settled during such processing will be reported to the relevant Euroclear system participant or Clearstream participant on such
business day. Cash received in Clearstream or the Euroclear system as a result of sales of the notes by or through a Clearstream participant or a Euroclear
system participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or the
Euroclear system cash account only as of the business day following settlement in DTC.
Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of debt securities among
participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may
be discontinued at any time.

UNDERWRITING (CONFLICTS OF INTEREST)
Barclays Capital Inc., J.P. Morgan Securities LLC and Wells Fargo Securities, LLC (collectively, the "Representatives"), as representatives of the
underwriters named below, and, together with Morgan Stanley & Co. LLC and TD Securities (USA) LLC, as joint book-running managers of the offering,
have entered into an underwriting agreement, dated the date of this prospectus supplement, with Edison International relating to the offer and sale of the
notes. In the underwriting agreement, Edison International has agreed to sell to each underwriter, and each underwriter has severally agreed to purchase
from Edison International, the principal amount of notes set forth opposite its name below:

The underwriting agreement provides that the obligations of the underwriters to purchase the notes included in this offering are subject to approval of
legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the notes if they purchase any of the notes.
The underwriters propose to offer the notes directly to the public at the public offering price set forth on the cover page of this prospectus supplement
and may offer the notes to dealers at the public offering price less a concession not to exceed 0.400% of the principal amount of the notes. The underwriters
may allow, and dealers may reallow a concession not to exceed 0.250% of the principal amount of the notes on sales to other dealers. After the initial
offering of the notes to the public, the underwriters may change the public offering price and concessions.
In connection with this offering, we will pay an underwriting discount to the underwriters of 0.650% of the principal amount of the notes.
In connection with the offering, the underwriters may purchase and sell notes in the open market. These transactions may include over-allotment,
syndicate covering transactions, and stabilizing transactions. Over-allotment involves syndicate sales of notes in excess of the principal amount of notes to
be purchased by the underwriter in the offering, which creates a syndicate short position. Syndicate covering transactions involve purchases of the notes in
the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing transactions consist of certain bids or
purchases of notes made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress.
The underwriters also may impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when
the underwriters, in covering syndicate short positions or making stabilizing purchases, repurchase notes originally sold by that syndicate member.

Final Prospectus Supplement
Any of these activities may have the effect of preventing or retarding a decline in the market price of the notes. They may also cause the price of the
notes to be higher than the price that otherwise would exist in the open market in the absence of these transactions. The underwriters may conduct these
transactions in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time.
We estimate that our total expenses for this offering, excluding the underwriting discount, will be $635,000.

Table of Contents
Certain of the underwriters and their affiliates have performed investment banking, commercial banking and advisory services for us and our
affiliates from time to time for which they have received customary fees and expenses. The underwriters and their affiliates may, from time to time,
engage in transactions with and perform services for us and our affiliates in the ordinary course of their business.
We expect delivery of the notes will be made against payment therefor on or about March 13, 2018, which is the third business day after the date of
this prospectus. Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the
parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of this prospectus or the next
succeeding business day will be required, by virtue of the fact that the notes initially will not settle in T+2, to specify an alternative settlement cycle at the
time of any such trade to prevent a failed settlement and should consult their own advisor.
We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, or to contribute to
payments the underwriters may be required to make because of any of those liabilities.
Conflicts of Interest
We intend to use approximately $500 million of the net proceeds from the offering of the notes to repay a borrowing under our term loan agreement.
See "Use of Proceeds." Certain lenders under the term loan agreement are affiliates of certain underwriters of this offering and will receive a portion of the
proceeds of this offering. Because certain of the underwriters, or their affiliates, will receive more than 5% of the net proceeds of the offering of the notes, a
conflict of interest under Rule 5121 of the Financial Industry Regulatory Authority, Inc. is deemed to exist. Accordingly, the offering of the notes will
conform with the requirements addressing conflicts of interest when distributing the securities of an affiliate set forth in Rule 5121. Additionally, client
accounts over which those certain underwriters or any affiliate has investment discretion are not permitted to purchase the notes, either directly or
indirectly, without the specific written approval of the accountholder.
The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities
trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing
and brokerage activities.
In the ordinary course of their various business activities, the underwriters and their respective 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, and such investment and securities activities may involve our securities and instruments or those of our
affiliates. See "Use of Proceeds." The underwriters and their respective affiliates may also make investment recommendations or publish or express
independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short
positions in such securities and instruments.
Selling Restrictions
No action has been or will be taken by us that would permit a public offering of the notes, or possession or distribution of this prospectus supplement
or the accompanying base prospectus or any other offering or publicity material relating to the notes, in any country or jurisdiction outside the United States
where, or in any circumstances in which, action for that purpose is required. Accordingly, the notes may not be offered or sold, directly or indirectly, and
this prospectus supplement, the accompanying base prospectus and any other offering or publicity material relating to the notes may not be distributed or
published, in or from any country or jurisdiction outside the United States except under circumstances that will result in compliance with applicable laws
and regulations.
