MIFID II PRODUCT GOVERNANCE/PROFESSIONAL INVESTORS AND ELIGIBLE COUNTERPARTIES ONLY TARGET MARKET

Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the notes has led to the conclusion that: (i) the target market for the notes is eligible counterparties and professional clients only, each as defined in Directive 2014/65/EU (as amended, “MiFID II”); and (ii) all channels for distribution of the notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the notes (a “distributor”) should take into consideration the manufacturers’ target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the notes (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

NOTICE TO PROSPECTIVE INVESTORS IN THE EUROPEAN ECONOMIC AREA

The notes offered hereby are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (the “EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of MiFID II; or (ii) a customer within the meaning of Directive (EU) 2016/97, as amended, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the “EU Prospectus Regulation”). Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”), for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of the notes in any member state of the EEA (“Member State”) will be made pursuant to an exemption under the EU Prospectus Regulation from the requirement to publish a prospectus for offers of the notes. Neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of the EU Prospectus Regulation.

Each person in a Member State of the EEA who receives any communication in respect of, or who acquires any notes under, the offers to the public contemplated in this prospectus supplement, or to whom the notes are otherwise made available, will be deemed to have represented, warranted, acknowledged and agreed to and with each underwriter and the Company that it and any person on whose behalf it acquires notes is not a “retail investor” (as defined above).

RISK FACTORS

In considering whether to purchase notes, you should carefully consider all of the information contained in or incorporated by reference into this prospectus supplement and the accompanying prospectus, including but not limited to the 2023 10-K and other information which may be incorporated by reference into this prospectus supplement and the accompanying prospectus as provided under “Where You Can Find More Information; Incorporation by Reference.” Although the risks are organized by headings, and each risk is discussed separately, many are interrelated. Our ability to achieve and maintain profitability and our ability to continue to fund our operations on an on-going basis will depend on a number of factors, some of which are beyond our control. In addition to the risk factors set forth below, you should carefully consider the information under “Special Note on Forward-Looking Statements” and the risk factors set forth under the caption “Risk Factors” contained in Item 1A of the 2023 10-K as well as the Company’s other filings with the SEC that are incorporated or deemed to be incorporated by reference into this prospectus supplement and the accompanying prospectus.

Risks Related to the Notes

The Company’s holding company structure may affect the Issuer’s and the Company’s ability to meet their respective obligations under the notes and guarantee.

The notes will be obligations of the Issuer and will be guaranteed only by the Company and not by any of the Company’s other subsidiaries. The Issuer is a wholly owned indirect subsidiary of the Company. Its assets consist of its investments in several wholly owned finance companies that function as treasury centers, which provide funding for various operating companies in Europe, Australia and Asia-Pacific. The finance companies’ assets consist of intercompany loans that they make or have made to the operating companies in their respective regions and the related interest receivables. The Company is a holding company and, accordingly, substantially all of its operations are conducted through its subsidiaries. As a result, the Issuer’s and the Company’s cash flow and their ability to make payments on their respective debt, including the notes and the guarantee, are dependent upon the earnings of these subsidiaries. The Company is dependent on the distribution of earnings, loans or other payments by the subsidiaries to it to service its obligations, including in respect of any payments pursuant to the guarantee of the notes and its other debt. In addition, to service debt, the Issuer, as a finance subsidiary, is also dependent on the earnings of the subsidiaries, the sale of certain assets of the subsidiaries and ability of the subsidiaries to repay principal and interest on the intercompany loans.

The Company’s subsidiaries are separate and distinct legal entities. These subsidiaries have no obligation to pay any amounts due on the notes or to provide the Issuer or the Company with funds for their respective payment obligations, whether by dividends, distributions, repayment or making of loans or other payments. In addition, any payment or repayment of dividends, distributions, loans or advances by these subsidiaries to the Issuer or the Company could be subject to legal or contractual restrictions. Payments to the Issuer or the Company by the subsidiaries will also be contingent upon the subsidiaries’ earnings and business considerations. If the Issuer or the Company do not have sufficient cash, or liquidity is not otherwise available, the Issuer and the Company may not be able to make principal or interest payments on outstanding debt, including under the notes and the guarantee.

Because of this structure, the notes will be structurally subordinated to all indebtedness and other liabilities of the Company’s subsidiaries (including liabilities to trade creditors) and the guarantee will be structurally subordinated to all indebtedness and other liabilities (including liabilities to trade creditors) of all of the Company’s subsidiaries, which means that creditors of the Company’s subsidiaries will have priority with respect to the assets of such subsidiaries over the Issuer’s and the Company’s claims (and therefore the claims of the Issuer’s and the Company’s creditors, including holders of the notes and the guarantee). As of December 31, 2023, the subsidiaries of the Company had approximately $15.2 billion of outstanding liabilities, which includes trade payables and excludes intercompany liabilities.

The notes do not restrict the Issuer’s or the Company’s ability to incur additional debt, repurchase their securities or to take other actions that could negatively impact holders of the notes.

The Issuer and the Company are not restricted under the terms of the notes from incurring additional debt or repurchasing their securities. In addition, the indenture will not contain any covenants which require the Issuer or the Company to achieve or maintain any minimum financial results relating to their financial position or results of operations. The Issuer’s and the Company’s ability to recapitalize, incur additional debt and take a number of other actions that are not limited by the terms of the notes could have the effect of diminishing their ability to make payments on the notes and the guarantee, as applicable.

An active trading market for the notes may not develop.

The notes are a new issue of securities with no established trading market. Although we intend to apply for listing of the notes for trading on The New York Stock Exchange, the listing application will be subject to approval by The New York Stock Exchange. If such a listing is obtained, we have no obligation to maintain such listing, and we may delist the notes at any time. We cannot provide you with any assurance regarding whether a trading market for the notes will develop, the ability of holders of the notes to sell their notes or the prices at which holders may be able to sell their notes. The underwriters have advised us that they currently intend to make a market in the notes. However, the underwriters are not obligated to do so, and any market-making with respect to the notes may be discontinued at any time without notice. If no active trading market develops, you may be unable to resell the notes at their fair market value or at any price.

If a trading market for the notes does develop, changes in our credit ratings or the debt markets could adversely affect the market price of the notes. The price for the notes will depend on many factors, including:

•        our credit ratings with major credit rating agencies;

•        the prevailing interest rates being paid by other companies similar to us;

•        our financial condition, financial performance and future prospects; and

•        the overall condition of the financial markets.

The condition of the financial markets and prevailing interest rates have fluctuated significantly in the past and are likely to fluctuate in the future. Such fluctuations could have an adverse effect on the price of the notes.

In addition, credit rating agencies continually review their ratings for the companies that they follow, including us. A negative change in our rating could have an adverse effect on the price of the notes.

The Issuer may not be able to repurchase the notes upon a change of control.

Upon the occurrence of a Change of Control Triggering Event, unless the Issuer has exercised its option to redeem the notes, each holder of such notes will have the right to require the Issuer to repurchase all or any part of such holder’s notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to the date of repurchase. If the Company experiences a Change of Control Triggering Event, there can be no assurance that the Issuer would have sufficient financial resources available to satisfy its obligations to repurchase the notes. The Issuer’s failure to repurchase the notes as required under the indenture governing the notes would result in a default under the indenture, which could have material adverse consequences for the Issuer, the Company and the holders of the notes. See “Description of Notes — Repurchase at the Option of Holders Upon Change of Control Triggering Event.”

In a lawsuit for payment on the notes, an investor may bear currency exchange risk.

The indenture governing the notes and the notes (including the guarantee) will be governed by the laws of the State of New York. Under New York law, a New York state court rendering a judgment on the notes or the guarantee would be required to render the judgment in euro. However, the judgment would be converted into U.S. dollars at the exchange rate prevailing on the date of entry of the judgment. Consequently, in a lawsuit for payment on the notes, investors would bear currency exchange risk until a New York state court judgment is entered, which could be a significant amount of time from the date the judgment is rendered. A federal court sitting in New York with diversity jurisdiction over a dispute arising in connection with the notes would apply New York law.

Laws in effect in the United Kingdom differ from the laws in effect in the United States and may afford less protection to holders of our securities. A judgment from a U.S. court may not be enforceable in the United Kingdom.

The Issuer is incorporated under the laws of England and Wales. The insolvency laws of the United Kingdom may not be as favorable to your interests as creditors as the laws of the U.S. or other jurisdictions with which you may be familiar. The Issuer will agree, in accordance with the terms of the indenture under which the notes and guarantee will be issued, to accept service of process in any suit, action or proceeding with respect to the indenture, the notes and the guarantee brought in any federal or state court located in the borough of Manhattan in New York City by an agent designated for such purpose, and to submit to the jurisdiction of such courts in connection with such suits, actions or proceedings. However, it may not be possible to enforce court judgments obtained in the United States against the Issuer in the United Kingdom based on the civil liability provisions of the U.S. federal or state securities laws. In addition, there is some uncertainty as to whether the courts of England and Wales would recognize or enforce judgments of U.S. courts obtained against us or our directors or officers or the directors of the Issuer based on the civil liability provisions of the U.S. federal or state securities laws or hear actions against us or those persons based on those laws. We have been advised that the United States currently does not have a treaty with the United Kingdom providing for the reciprocal recognition and enforcement of judgments (other than arbitration awards) in civil and commercial matters. Therefore, a final judgment for the payment of money rendered by any U.S. federal or state court based on civil liability, whether or not based solely on U.S. federal or state securities laws, would not automatically be enforceable in England and Wales.

An investment in the notes by a holder whose home currency is not the euro entails significant risks.

All payments of interest on and the principal of the notes and any redemption or repurchase price for the notes will be made in euro. An investment in the notes by a holder whose home currency is not the euro entails significant risks. These risks include the possibility of significant changes in rates of exchange between the holder’s home currency and the euro and the possibility of the imposition or subsequent modification of foreign exchange controls with respect to the euro or the investor’s home currency. These risks generally depend on factors over which we have no control, such as economic, financial and political events and the supply of and demand for the relevant currencies.

In the past, rates of exchange between the euro and certain currencies have been highly volatile, and each holder should be aware that volatility may occur in the future. Fluctuations in any particular exchange rate that have occurred in the past, however, are not necessarily indicative of fluctuations in the rate that may occur during the term of the notes. Depreciation of the euro against the holder’s home currency would result in a decrease in the effective yield of the notes below its coupon rate and, in certain circumstances, could result in a loss to the holder. If you are a U.S. holder, see “Certain U.S. Federal Income Tax Considerations” for a summary of certain U.S. federal income tax considerations relevant to the purchase, ownership and disposition of the notes, related to the notes being denominated in euro. The European Union or one or more of its Member States may, in the future, impose exchange controls and modify any exchange controls imposed, which controls could affect exchange rates, as well as the availability of euro at the time of payment of principal of, interest on, or any redemption payment or additional amounts with respect to the notes.

This description of foreign exchange risks does not describe all the risks of an investment in securities, including, in particular, the notes, that are denominated or payable in a currency other than an investor’s home currency. You should consult your own financial and legal advisors as to the risks involved in an investment in the notes.

The notes permit us to make payments in U.S. dollars if we are unable to obtain euro.

If the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then-Member States of the European Economic and Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the notes will be made in U.S. dollars until the euro is again available to us or so used. In such circumstances, the amount payable on any date in euro will be converted into U.S. dollars by us at the most recently available market exchange rate (as defined in “Description

of Notes — Payments in Euro”) for the euro. Any payment in respect of the notes so made in U.S. dollars will not constitute an event of default under the notes or the indenture governing the notes. See “Description of Notes — Payments in Euro.”

The notes will initially be held in book-entry form and therefore investors must rely on the procedures of Euroclear and Clearstream, Luxembourg to exercise any rights and remedies.

So long as Euroclear or Clearstream, Luxembourg or their common depositary or nominee is the registered holder of the notes issued in the form of one or more global notes, Euroclear, Clearstream, Luxembourg or such common depositary or nominee, as the case may be, will be considered the sole owner or holder of the notes represented by the global notes for all purposes under the indenture and the notes. Payments of principal, interest and premium and additional amounts, if any, in respect of the global notes will be made to Euroclear, Clearstream, Luxembourg, such common depositary or such nominee, as the case may be, as registered holder thereof. After payment to the common depositary for Euroclear and Clearstream, Luxembourg, we will have no responsibility or liability for the payment of interest, principal or other amounts to the owners of book-entry interests. Accordingly, if investors own a book-entry interest, they must rely on the procedures of Euroclear and Clearstream, Luxembourg and, if investors are not participants in Euroclear and Clearstream, Luxembourg, they must rely on the procedures of the participant through which they own their interest, to receive such payments or to exercise any other rights and obligations of a holder of notes under the indenture.

Unlike the holders of the notes themselves, owners of book-entry interests will not have the direct right to act upon our solicitations for consents, requests for waivers or other actions from holders of the notes. Instead, if an investor owns a book-entry interest, it will be permitted to act only to the extent it has received appropriate proxies to do so from Euroclear and Clearstream, Luxembourg. The procedures implemented for the granting of such proxies may not be sufficient to enable such investor to vote on a timely basis.

Similarly, upon the occurrence of an event of default under the indenture, unless and until definitive or certificated registered notes are issued in respect of all book-entry interests, if investors own book-entry interests, they will be restricted to acting through Euroclear and Clearstream, Luxembourg. The procedures to be implemented through Euroclear and Clearstream, Luxembourg, may not be adequate to ensure the timely exercise of rights under the notes. See “Description of Notes — Book-Entry; Delivery and Form” in this prospectus supplement.

Trading in the clearing system is subject to minimum denomination requirements.

The terms of the notes provide that notes will be issued with a minimum denomination of €100,000 and multiples of €1,000 in excess thereof. It is possible that the clearing systems may process trades that could result in amounts being held in denominations smaller than the minimum denominations. If definitive notes are required to be issued in relation to such notes in accordance with the provisions of the relevant global notes, a holder who does not have the minimum denomination or a multiple of €1,000 in excess thereof in its account with the relevant clearing system at the relevant time may not receive all of its entitlement in the form of definitive notes unless and until such time as its holding satisfies the minimum denomination requirement.

CAPITALIZATION

The following table sets forth the Company’s actual consolidated cash and cash equivalents and capitalization, as of December 31, 2023, and as adjusted to reflect the issuance and sale of the notes offered hereby. You should read this table in conjunction with the Company’s financial statements and related notes and other financial and operating data included elsewhere in or incorporated by reference into this prospectus supplement and the accompanying prospectus.

•        Sinking fund: The notes will not be subject to any sinking fund.

•        Trustee: Deutsche Bank Trust Company Americas

•        Paying Agent, Transfer Agent and Registrar: Deutsche Bank Trust Company Americas

The Issuer may, without the consent of the holders, issue additional notes having the same ranking and the same interest rate, maturity and other terms as the notes offered hereby (except for the issue date, the price to the public, the payment of interest accruing prior to the issue date of such additional notes or except for first payment of interest following the issue date of such additional notes). Any such additional notes will be a part of the series having the same terms as the notes, provided that such additional notes subsequently issued are fungible for U.S. federal income tax purposes with any notes previously issued.

Guarantee

The Company will fully and unconditionally guarantee the due and punctual payment of all obligations of the Issuer under the indenture and the notes, whether for the payment of principal of, premium, if any, or interest or any Additional Amounts (as defined in the section “Description of International Debt Securities — Payment of Additional Amounts” in the accompanying prospectus), on the notes or otherwise, when and as the same shall become due and payable, whether at maturity, upon redemption or otherwise. The guarantee will be an unsecured and unsubordinated obligation of the Company and will rank equally with all of its other unsecured and unsubordinated obligations.

Payments in Euro

Initial holders will be required to pay for the notes in euro, and all payments of interest, principal and premium, if any, including payments made upon any redemption or repurchase of the notes, will be payable in euro. If, on or after the date of this prospectus supplement, the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then-Member States of the European Economic and Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the notes will be made in U.S. dollars until the euro is again available to us or so used. In such circumstances, the amount payable on any date in euro will be converted into U.S. dollars by us at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second Business Day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the most recent U.S. dollar/euro exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date (the “market exchange rate”). Any payment in respect of the notes so made in U.S. dollars will not constitute an event of default under the notes or the indenture. Neither the trustee nor the paying agent for the notes shall have any responsibility for any calculation or conversion in connection with the foregoing.

Holders of the notes will be subject to foreign exchange risks as to payments of principal and interest that may have important economic and tax consequences to them. See “Risk Factors — An investment in the notes by a holder whose home currency is not the euro entails significant risks.”

Business Day

For purposes of the notes, “Business Day” means any day other than a Saturday or Sunday, (1) which is not a day on which banking institutions in The City of New York or London are authorized or required by law, regulation or executive order to close and (2) on which the Trans-European Automated Real Time Gross Settlement Express Transfer system (the “TARGET2” system), or any successor thereto, is open.

Optional Redemption

Prior to            (the date that is            months prior to the maturity date of the notes (the “par call date”)), the notes will be redeemable, as a whole or in part, at the Issuer’s option, at any time or from time to time, upon mailed notice (or electronic notice, as applicable) to the registered address of each holder of such notes at least 15 days but not more than 60 days prior to the redemption. The redemption price, as determined by us, will be equal to the greater of (1) 100% of the principal amount of the notes to be redeemed and (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) on such notes discounted to the date of redemption, on an annual basis (assuming an ACTUAL/ACTUAL (ICMA) day count fraction), at the applicable Comparable Government Bond Rate (as defined below) plus            basis points, plus accrued and unpaid interest thereon, if any, to, but excluding, the redemption date.

On or after the par call date, the notes will be redeemable, as a whole or in part, at the Issuer’s option, at any time or from time to time, upon mailed notice (or electronic notice, as applicable) to the registered address of each holder of such notes at least 15 days but not more than 60 days prior to the redemption at a redemption price of 100% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to, but excluding, the redemption date.

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, at the discretion of an independent investment bank selected by us, a German federal government bond whose maturity is closest to the maturity of the notes to be redeemed, or if such independent investment bank in its discretion determines that such similar bond is not in issue, such other German federal government bond as such independent investment bank may, with the advice of three brokers of, and/or market makers in, German federal government bonds selected by us, determine to be appropriate for determining the Comparable Government Bond Rate.

“Comparable Government Bond Rate” means the price, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), at which the gross redemption yield on the notes to be redeemed, if they were to be purchased at such price on the third Business Day prior to the date fixed for redemption, of the Comparable Government Bond would be equal to the gross redemption yield on such Business Day of the Comparable Government Bond on the basis of the middle market price of such Comparable Government Bond prevailing at 11:00 a.m. (London time) on such Business Day as determined by an independent investment bank selected by us.

“Remaining Scheduled Payments” means, with respect to each note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related redemption date but for such redemption calculated as if the maturity date of such note was the par call date; provided, however, that, if such redemption date is not an interest payment date with respect to such note, the amount of the next succeeding scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to, but excluding, such redemption date.

On and after the redemption date, interest will cease to accrue on the notes or any portion of the notes called for redemption (unless we default in the payment of the redemption price and accrued interest). On or before any redemption date, we will deposit with the paying agent (or the trustee) money sufficient to pay the redemption price of and accrued interest on the notes to be redeemed on such date.

If less than all of the notes are to be redeemed, the notes to be redeemed shall be selected by such method as the trustee deems fair and appropriate, subject to the procedures of Euroclear and Clearstream, Luxembourg as to global notes.

Repurchase at the Option of Holders Upon Change of Control Triggering Event

Upon the occurrence of a Change of Control Triggering Event (as defined below), unless the Issuer has exercised its option to redeem the notes as described under “— Optional Redemption,” each holder of such notes will have the right to require the Issuer to repurchase all or a portion of such holder’s notes pursuant to a change of control offer described below (a “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of repurchase (the “Change of Control Payment”), subject to the right of holders of notes on the relevant record date to receive interest due on the relevant interest payment date.

Within 30 days following the date upon which the Issuer becomes aware that a Change of Control Triggering Event has occurred, or at the Issuer’s option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Issuer will be required to send, by first class mail or electronic delivery, a notice to each holder of notes, with a copy to the trustee, which notice will govern the terms of the Change of Control Offer. Such notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is mailed or delivered, other than as may be required by law (the “Change of Control Payment Date”). The notice, if mailed or delivered prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date.

The Issuer will not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Issuer and such third party purchases all notes properly tendered and not withdrawn under its offer.

To the extent that the Issuer is required to offer to repurchase the notes upon the occurrence of a Change of Control Triggering Event, it may not have sufficient funds to purchase the notes in cash at such time. In addition, the Issuer’s ability to purchase the notes for cash may be limited by law or the terms of other agreements relating to its indebtedness outstanding at the time. The failure to make such purchase would result in a default under the notes.

The Issuer will be required to comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Offer provisions of the indenture and the notes, the Issuer will be required to comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Offer provisions of the indenture and the notes by virtue of any such compliance.

On the Change of Control Payment Date, the indenture will provide that the Issuer will, to the extent lawful:

•        accept for payment all notes or portions of notes properly tendered and not withdrawn pursuant to the Change of Control Offer;

•        deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions of notes properly tendered and not withdrawn; and

•        deliver or cause to be delivered to the trustee the notes properly accepted together with an officer’s certificate stating the aggregate principal amount of notes or portions of notes being repurchased.

“Below Investment Grade Rating Event” occurs if both the rating on the notes is lowered by each of the Rating Agencies and such notes are rated below Investment Grade by each of the Rating Agencies on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended so long as the rating of the notes is under publicly announced consideration for possible downgrade by any of the Rating Agencies); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Triggering Event hereunder) if any of the Rating Agencies making the reduction in rating to which this definition would otherwise apply does not announce or publicly confirm or inform the trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event).

“Change of Control” means the occurrence of any of the following:

(1)    the sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the assets of the Company and its subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than to the Company or one of its subsidiaries;

(2)    the consummation of any transaction (including without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act), other than the Company or one of its wholly owned subsidiaries, becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the then outstanding shares of the Company’s Voting Stock, measured by voting power rather than number of shares; or

(3)    the adoption of a plan relating to the liquidation or dissolution of the Company.

Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control if (i) the Company becomes a wholly owned subsidiary of a holding company and (ii) the holders of the Voting Stock of such holding company immediately following such transaction are substantially the same as the holders of the Company’s Voting Stock immediately prior to such transaction.

The definition of Change of Control includes a phrase relating to the sale, transfer, conveyance or other disposition of “all or substantially all” of the assets of the Company and its subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a holder of notes to require the Issuer to repurchase such notes as a result of a sale, transfer, conveyance or other disposition of less than all of the assets of the Company and its subsidiaries taken as a whole to another Person or group may be uncertain.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

“Investment Grade” means a rating equal to or higher than Baa3 (or its equivalent under any successor rating categories) by Moody’s and BBB- (or its equivalent under any successor rating categories) by S&P, or, in each case, if such Rating Agency ceases to rate the notes or fails to make a rating of the notes publicly available for reasons outside of the Issuer’s and the Company’s control, the equivalent investment grade credit rating by the replacement agency selected by the Issuer in accordance with the procedures described below.

“Moody’s” means Moody’s Investors Service, Inc., and its successors.

“Rating Agencies” means (1) each of Moody’s and S&P; and (2) if any of Moody’s or S&P ceases to rate the notes or fails to make a rating of the notes publicly available for reasons outside of the Issuer’s and the Company’s control, a “nationally recognized statistical rating organization,” as defined in Section 3(a)(62) of the Exchange Act, selected by the Issuer as a replacement agency for Moody’s or S&P, or both of them, as the case may be.

“S&P” means S&P Global Ratings, and its successors.

“Voting Stock” means, with respect to any person, capital stock of any class or kind the holders of which are ordinarily, in the absence of contingencies, entitled to vote for the election of directors (or persons performing similar functions) of such person, even if the right so to vote has been suspended by the happening of such a contingency.

Payment of Additional Amounts

Subject to the exceptions and limitations set forth in the accompanying prospectus, the Issuer or the Company may be required to pay to certain noteholders such additional amounts as may be necessary so that the net amount received by each holder of the notes after withholding or deduction for or on account of any present or future taxes, duties, levies, imposts, assessments or governmental charges of whatever nature imposed or levied by or on behalf of the United Kingdom or the United States (or other jurisdiction in which the Issuer, the Company or, in each case, any successor thereof, may be incorporated, organized, or otherwise resident for tax purposes, or engaged in business for tax purposes, as applicable, or any political subdivision thereof or therein having the power to tax, or any jurisdiction from or through which payment is made by or on behalf of the Issuer or the Company), will equal the amount that such holder would have received if such taxes had not been required to be withheld or deducted. See “Description of International Debt Securities — Payment of Additional Amounts” in the accompanying prospectus.

Redemption Upon Changes in Withholding Taxes

The Issuer may redeem all, but not less than all, of the notes in the event of certain changes in the tax law of the United Kingdom or the United States (or other jurisdiction in which the Issuer, the Company or, in each case, any successor thereof, may be incorporated, organized, or otherwise resident for tax purposes, or engaged in business for tax purposes, as applicable, or any political subdivision thereof or therein having the power to tax, or any jurisdiction from or through which payment is made by or on behalf of the Issuer or the Company) if, based on a written opinion of independent counsel chosen by the Issuer or the Company, the Issuer or the Company has become, or there is a substantial probability that the Issuer or the Company will become, obligated to pay additional amounts on the notes as described above. This redemption would be at a redemption price equal to 100% of the principal amount of the notes, together with accrued and unpaid interest on the notes to the redemption date. See “Description of International Debt Securities — Redemption Upon Changes in Withholding Taxes” in the accompanying prospectus.

Certain Covenants

The indenture will not contain any provisions that would limit the Issuer’s or the Company’s ability to incur unsecured indebtedness or that would afford holders of notes protection in the event of a sudden and significant decline in the credit quality or rating of the Company or a takeover, recapitalization or highly leveraged or similar transaction involving the Company.

Limitation on Liens

The Company will not, and will not permit any of its Subsidiaries to, create or suffer to exist any Lien on or with respect to any of the Company’s properties, whether now owned or hereafter acquired, to secure any Debt of the Company, any direct or indirect Subsidiary or any other Person without securing the notes equally and ratably with such Debt to which such Liens relate for so long as such Debt shall be so secured, other than:

•        Permitted Liens;

•        Liens existing on the date of this prospectus supplement;

•        Liens on property of a Person existing at the time such Person is merged into, consolidated with, or acquired by the Company or any Subsidiary of the Company or becomes a Subsidiary of the Company; provided that such Liens were not created in contemplation of such merger, consolidation or acquisition and do not extend to any assets other than those of the Person so merged into or consolidated with the Company or such Subsidiary or acquired by the Company or such Subsidiary;

•        Liens granted by Subsidiaries of the Company (other than the Issuer) to secure Debt owed to the Company or a wholly owned Subsidiary of the Company;

•        Liens arising out of a judgment, decree or order of court being contested in good faith by appropriate proceedings, provided that adequate reserves with respect thereto are maintained on the books of the Company or the books of its Subsidiaries, as the case may be, in conformity with U.S. GAAP;

•        Debt of a Person existing at the time such Person is merged into or consolidated with the Company or becomes a Subsidiary of the Company provided that such Debt was not created in contemplation of such merger, consolidation or acquisition and provided further that the aggregate principal amount of such Debt shall not exceed $50,000,000 at any time outstanding;

•        Liens to secure any extension, renewal, refinancing or refunding (or successive extensions, renewals, refinancings or refundings), in whole or in part, of any Debt secured by Liens referred to above or Liens created in connection with any amendment, consent or waiver relating to such Debt, so long as such Lien does not extend to any other property, the amount of Debt secured is not increased (other than by the amount equal to any costs and expenses incurred in connection with any extension, renewal, refinancing or refunding) and the Debt so secured does not exceed the fair market value (as determined by the board of directors of the Company in good faith) of the assets subject to such Liens at the time of such extension, renewal, refinancing or refunding, or such amendment, consent or waiver, as the case may be;

•        any assignment of accounts receivable (a) by and among the Company and its Subsidiaries or (b) pursuant to non-recourse factoring or similar arrangements or otherwise in an aggregate amount not to exceed in any fiscal year the greater of $500,000,000 (measured as the face value of such accounts receivable at the time of assignment) and 10.0% of the consolidated accounts receivable of the Company and its Subsidiaries as reflected in the consolidated balance sheet of the Company as of the end of the fiscal year of the Company most recently ended prior to such assignment for which financial statements are available; and

•        (a) Liens otherwise prohibited by this covenant, securing Debt or other obligations in an aggregate amount at any time outstanding plus (b) the aggregate face value at the time of assignment of such accounts receivable assigned, the assignment of which is not otherwise permitted by the foregoing exceptions, in an aggregate amount not to exceed 20% of Consolidated Net Worth of the Company and its Subsidiaries as set forth in the Company’s most recently available financial statements.

In addition, the description of the clearing systems in this section reflects the Issuer’s understanding of the rules and procedures of Euroclear and Clearstream, Luxembourg as they are currently in effect. Those clearing systems could change their rules and procedures at any time.

The notes will initially be represented by one or more fully registered global notes without interest coupons. Each such global note will be deposited with, or on behalf of, a common depositary, and registered in the name of the nominee of the common depositary for the accounts of Euroclear and Clearstream, Luxembourg. Except as described herein, certificates will not be issued in exchange for beneficial interests in the global notes.

Except as set forth below, the global notes may be transferred, in whole and not in part, only to Euroclear or Clearstream, Luxembourg or their respective nominees.

The Issuer has been advised by Euroclear and Clearstream, Luxembourg, respectively, as follows:

Euroclear

Euroclear advises that it was created in 1968 to hold securities for participants of Euroclear (“Euroclear 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 includes various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V. (the “Euroclear Operator”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. 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.

The Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, or the Euroclear Terms and Conditions, and applicable Belgian law govern securities clearance accounts and cash accounts with the Euroclear Operator. Specifically, the Euroclear Terms and Conditions govern:

•        transfers of securities and cash within Euroclear;

•        withdrawal of securities and cash from Euroclear; and

•        receipt of payments with respect to securities in Euroclear.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a summary of certain U.S. federal income tax considerations relevant to the acquisition, ownership and disposition of the notes. The discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury Regulations issued thereunder, Internal Revenue Service (the “IRS”) rulings and pronouncements and judicial decisions now in effect, all of which are subject to differing interpretations and subject to change at any time. Any such change or differing interpretations may be applied retroactively in a manner that could adversely affect a holder of notes. This discussion does not address all of the U.S. federal income tax considerations that may be relevant to a holder in light of such holder’s particular circumstances (such as the effects of Section 451(b) of the Code conforming the timing of certain income accruals to financial statements) or to holders subject to special rules, such as banks and other financial institutions, former citizens or former permanent residents of the United States, insurance companies, brokers, dealers in securities or currencies, traders in securities that elect to use the mark-to-market method of accounting for their securities holdings, entities or arrangements treated as partnerships for U.S. federal tax purposes or other pass-through entities or arrangements or investors therein, regulated investment companies, personal holding companies, pension funds, real estate investment trusts, individual retirement and other tax-deferred accounts, holders subject to the alternative minimum tax, “controlled foreign corporations” or “passive foreign investment companies” (as such terms are defined in the Code), U.S. Holders (as defined below) whose functional currency is not the U.S. dollar, tax-exempt organizations and persons holding the notes as part of a “straddle,” “hedge,” “conversion transaction” or other integrated transaction. In addition, this discussion is limited to holders who purchased the notes for cash at original issue and at their “issue price” (generally, the first price at which a substantial amount of the notes are sold to investors for cash (excluding sales to bondhouses, brokers or similar organizations acting in the capacity of underwriters, placement agents or wholesalers)). Moreover, the effect of any applicable state, local or non-U.S. tax laws, and any U.S. federal tax other than income tax, such as estate and gift tax, is not discussed. The discussion deals only with notes held as “capital assets” within the meaning of the Code (generally, property held for investment).

As used herein, “U.S. Holder” means a beneficial owner of the notes that is or is treated for U.S. federal income tax purposes as:

•        an individual that is a citizen or resident of the United States;

•        a corporation created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•        an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

•        a trust, if (i) a U.S. court can exercise primary supervision over the administration of the trust and (ii) one or more “United States persons,” as defined in the Code, have the authority to control all substantial decisions of the trust, or it has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a United States person.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds the notes, the tax treatment of a partner generally will depend on the status of the partner and the activities of the partnership. Such entities and partners of such entities should consult their tax advisors about the U.S. federal income tax consequences of the acquisition, ownership, and disposition of a note.

No ruling from the IRS or opinion of counsel has or will be sought with respect to the matters discussed below. There can be no assurance that the IRS will not take a different position concerning the tax considerations of the acquisition, ownership or disposition of the notes or that any such position would not be sustained.

THIS DISCUSSION IS FOR GENERAL INFORMATIONAL PURPOSES ONLY AND SHOULD NOT BE VIEWED AS TAX ADVICE. PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS WITH REGARD TO THE APPLICATION OF THE TAX CONSIDERATIONS DISCUSSED BELOW TO THEIR PARTICULAR SITUATIONS AS WELL AS THE APPLICATION OF ANY STATE, LOCAL, NON-U.S. OR OTHER TAX LAWS, INCLUDING GIFT AND ESTATE TAX LAWS, ANY TAX TREATIES, AND THE POSSIBLE EFFECTS OF ANY CHANGES IN U.S. OR OTHER TAX LAWS.

Ownership and Disposition of Notes

Additional Payments

In certain circumstances (see “Description of Notes — Payment of Additional Amounts” and “Description of Notes — Repurchase at the Option of Holders Upon Change of Control Triggering Event”), we may be obligated to pay amounts in excess of principal plus stated interest on the notes. U.S. Treasury Regulations provide special rules for contingent payment debt instruments, which, if applicable, could cause the timing, amount, and character of a holder’s income, gain, or loss with respect to the notes to be different from the consequences discussed below. However, the relevant U.S. Treasury Regulations state that, for purposes of determining whether a debt instrument is a contingent payment debt instrument, contingencies which are either remote or incidental as of the issue date are ignored. We believe that, as of the issue date, the likelihood of paying such additional amounts on the notes is remote and/or incidental. Accordingly, we do not intend to treat the notes as contingent payment debt instruments. Our determination that these contingencies are remote and/or incidental is binding on a holder unless such holder discloses its contrary position in the manner required by applicable U.S. Treasury Regulations. Our determination is not binding on the IRS, however, which may take a different position and treat the notes as contingent payment debt instruments. The remainder of this discussion assumes that the notes are not treated as contingent payment debt instruments.

U.S. Holders

This discussion is a summary of the U.S. federal income tax considerations that will apply to U.S. Holders. Certain U.S. federal income tax considerations applicable to non-U.S. Holders are described below under the heading “— Non-U.S. Holders.”

Stated Interest

Payments of stated interest on the notes generally will be treated as “qualified stated interest” for U.S. federal income tax purposes and taxable to a U.S. Holder as ordinary interest income at the time that such payments are received or accrued, in accordance with such U.S. Holder’s regular method of accounting for U.S. federal income tax purposes.

A U.S. Holder that uses the cash method of tax accounting and that receives a payment of interest (or receives proceeds from a sale, exchange or other disposition attributable to accrued interest) will be required to include in income the U.S. dollar value of the euro payment (determined based on a spot rate on the date the payment is received).

A U.S. Holder that uses the accrual method of tax accounting will be required to include in income the U.S. dollar value of the amount of interest income that accrues with respect to a note during an accrual period. The U.S. dollar value of the accrued income will be determined by translating the income at the average rate of exchange for the accrual period or, with respect to an accrual period that spans two taxable years, at the average rate for the partial period within the taxable year. The U.S. Holder will recognize foreign currency gain or loss (which will be treated as ordinary income or loss) with respect to accrued interest income on the date the interest payment (or proceeds from the sale, exchange or other disposition attributable to accrued interest) is actually received. The amount of ordinary income or loss recognized will equal the difference between the U.S. dollar value of the euro payment received (determined based on a spot rate on the date the payment is received) in respect of the accrual period and the U.S. dollar value of interest income that has accrued during the accrual period (as determined above). A U.S. Holder may elect to translate interest income for an interest accrual period into U.S. dollars at the spot rate on the last day of the interest accrual period (or, in the case of a partial accrual period, the spot rate on the last day of the taxable year) or, if the date of receipt is within five business days of the last day of the interest accrual period, the spot rate on the date of receipt. A U.S. Holder that makes this election must apply it consistently to all debt instruments from year to year and cannot change the election without the consent of the IRS.

A U.S. Holder’s tax basis in the euro received on a payment of interest will generally equal its U.S. dollar value based on the spot rate on the date the payment is received. Any gain or loss realized by a U.S. Holder on a sale or other taxable disposition of euro (including its exchange for U.S. dollars) will be ordinary income or loss.

Original Issue Discount

It is expected (and this summary assumes) that the notes will not be issued with more than a de minimis amount of original issue discount (“OID”) for U.S. federal income tax purposes. In the event the notes are issued with more than de minimis OID, U.S. Holders will be required to include OID in income on a constant-yield basis over the term of the notes.

Foreign Tax Credits

Interest (including Additional Amounts) paid by the Issuer with respect to a note will constitute foreign source income for U.S. federal income tax purposes, which may be relevant to U.S. Holders in calculating their foreign tax credit limitations. A U.S. Holder may be entitled to deduct or credit foreign withheld tax, if any, subject to applicable limitations in the Code and the final foreign tax credit Treasury Regulations issued on December 28, 2021. These Treasury Regulations apply to foreign taxes paid or accrued in taxable years beginning on or after December 28, 2021 and impose additional requirements for foreign taxes to be eligible for credit, however, the IRS has indicated that taxpayers may defer the application of many of these additional requirements until further notice. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For U.S. foreign tax credit purposes, interest income on a note generally will be considered “passive category” income. The rules governing the U.S. foreign tax credit are complex, and U.S. Holders are encouraged to consult their tax advisors regarding the availability of the credit under their particular circumstances, including under the final foreign tax credit Treasury Regulations.

Sale, Exchange, Redemption, Retirement or Other Taxable Disposition of the Notes

Except to the extent of foreign currency gain or loss (as described below), a U.S. Holder will generally recognize gain or loss on the sale, exchange, redemption, retirement or other taxable disposition of a note equal to the difference, if any, between the amount realized upon the disposition (other than amounts attributable to any accrued and unpaid interest, which will be taxable as described under “— Stated Interest” above, to the extent not previously taxed) and the U.S. Holder’s adjusted tax basis in the note. A U.S. Holder’s amount realized upon the disposition equals the U.S. dollar value of the euro received in the sale, exchange, redemption, retirement or other taxable disposition calculated at the spot rate in effect on the date of disposition. If the notes are traded on an established securities market, a cash method taxpayer who buys or sells a note is required to translate units of euro paid or received into U.S. dollars at the spot rate on the settlement date of the purchase or sale and an accrual method taxpayer may elect the same treatment for all purchases and sales of such notes. This election by accrual method taxpayers cannot be changed without the consent of the IRS. A U.S. Holder’s adjusted basis in a note will equal the U.S. dollar value of the euro amount paid for the note, determined on the date of the purchase. A U.S. Holder who purchases a note with previously owned euro will recognize ordinary income or loss in an amount equal to the difference, if any, between such U.S. Holder’s tax basis in the euro and the U.S. dollar fair market value of the note on the date of purchase.

Except to the extent of foreign currency gain or loss (as described below), any gain or loss generally will be a capital gain or loss and will be a long-term capital gain or loss if the U.S. Holder has held the note for more than one year. Certain non-corporate U.S. Holders (including individuals) currently are eligible for preferential rates of U.S. federal income tax in respect of long-term capital gain. The deductibility of capital losses by U.S. Holders is subject to limitations under the Code.

A U.S. Holder may recognize foreign currency gain or loss upon the sale, exchange, redemption, retirement or other taxable disposition of a note as a result of fluctuations in the euro-U.S. dollar exchange rate. Gain or loss attributable to such fluctuations will equal the difference between (i) the U.S. dollar value of the U.S. Holder’s purchase price in euro of the note, determined using the spot rate on the date the note is disposed of, and (ii) the U.S. dollar value of the U.S. Holder’s purchase price in euro of the note, determined using the spot rate on the date the U.S. Holder acquired the note. The foreign currency gain or loss will be recognized only to the extent of the total gain or loss realized by a U.S. Holder on the sale, exchange or other taxable disposition of the note. Any such gain or loss generally will be U.S. source ordinary income or loss. If a U.S. Holder recognizes a loss upon a sale or other taxable disposition of a note and such loss is above certain thresholds, the U.S. Holder may be required to file a disclosure statement with the IRS. U.S. Holders should consult their tax advisors regarding this reporting obligation.

A U.S. Holder will have a tax basis in any euro received on the sale, exchange or other taxable disposition of a note equal to the U.S. dollar value of the euro, determined at the time of sale, exchange or other taxable disposition. Any gain or loss realized by a U.S. Holder on a sale or other taxable disposition of euro (including its exchange for U.S. dollars) will be ordinary income or loss.

Surtax on Net Investment Income

Certain U.S. Holders who are individuals, estates or trusts will be required to pay a 3.8% surtax on the lesser of (i) the U.S. Holder’s “net investment income” (or “undistributed net investment income” in the case of an estate or trust) for the relevant taxable year and (ii) the excess of the U.S. 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 U.S. Holder’s net investment income generally will include interest and gains from the sale or other taxable disposition of the notes. U.S. Holders should consult their own tax advisors regarding the effect, if any, of this surtax on their investment in the notes.

Tax Return Disclosure Obligation with Respect to Foreign Financial Assets

Certain owners of “specified foreign financial assets” with an aggregate value in excess of certain threshold amounts may be required to file an information report with respect to such assets with their tax returns. “Specified foreign financial assets” include any financial accounts maintained by foreign financial institutions, as well as any of the following, but only if they are not held in accounts maintained by financial institutions: (i) stocks and securities issued by non-U.S. persons, (ii) financial instruments and contracts held for investment that have non-U.S. issuers or counterparties, and (iii) interests in foreign entities. Under these rules, the notes (or accounts in which the notes are held) may be treated as “specified foreign financial assets.” U.S. Holders are urged to consult their own tax advisors regarding the application of this reporting requirement to their investment in the notes.

Backup Withholding and Information Reporting

A U.S. Holder may be subject to information reporting and backup withholding (currently at a rate of 24%) with respect to interest on the notes and the proceeds received upon the sale or other disposition of such notes (including a redemption or retirement). Certain U.S. Holders (currently including, among others, certain tax-exempt organizations and corporations) generally are not subject to information reporting or backup withholding. A U.S. Holder will be subject to backup withholding if such holder is not otherwise exempt and such holder:

•        fails to furnish its taxpayer identification number (“TIN”), which, for an individual, is ordinarily his or her social security number, or a certification of exempt status;

•        furnishes an incorrect TIN;

•        is notified by the IRS that it has failed to properly report payments of interest or dividends; or

•        fails to certify, under penalties of perjury (generally on a properly completed and executed IRS Form W-9) that it has furnished a correct TIN and that the IRS has not notified the U.S. Holder that it is subject to backup withholding.

U.S. Holders should consult their own tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption, if applicable. Backup withholding is not an additional tax, and taxpayers may use amounts withheld as a credit against their U.S. federal income tax liability or may claim a refund as long as they timely provide certain information to the IRS.

Non-U.S. Holders

The following is a summary of certain U.S. federal income and withholding tax considerations generally applicable to non-U.S. Holders. A “Non-U.S. Holder” is a beneficial owner of the notes that is neither a U.S. Holder nor a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes). Non-U.S. Holders are encouraged to consult their own tax advisors concerning the relevant U.S. federal, state and local and any non-U.S. tax considerations that may be relevant to their particular situations.

Interest

Subject to the discussion below under the heading “— Backup Withholding and Information Reporting”, interest paid on a note (which, for purposes of this discussion, includes any payments on the note that may be treated as interest for U.S. federal income tax purposes) to a Non-U.S. Holder generally will not be subject to U.S. federal income tax or withholding tax, unless such payments are effectively connected with such Non-U.S. Holder’s conduct of a U.S. trade or business (and, if required by an applicable tax treaty, are attributable to a “permanent establishment” or “fixed base” maintained by the Non-U.S. Holder in the United States). A Non-U.S. Holder generally will be subject to U.S. federal income tax in the same manner as a U.S. Holder (but without regard to the surtax on net investment income discussed above), however, with respect to interest on a note if such interest is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable tax treaty, is attributable to a “permanent establishment” or “fixed base” maintained by the Non-U.S. Holder in the United States). Under certain circumstances, interest that is effectively connected with a corporate Non-U.S. Holder’s conduct of a trade or business within the United States may be subject to an additional “branch profits tax” at a 30% rate (or a lower applicable treaty rate, provided certain certification requirements are met). For this purpose, interest on a note will be included in earnings and profits if such interest is effectively connected with the conduct by a corporate Non-U.S. Holder of a trade or business in the United States.

Sale, Exchange, Redemption, Retirement or Other Taxable Disposition of the Notes

Subject to the discussion below under the heading “— Backup Withholding and Information Reporting”, a Non-U.S. Holder generally will not be subject to U.S. federal income tax or withholding tax on gain recognized on the sale, exchange, redemption, retirement or other taxable disposition of a note unless:

•        that gain is effectively connected with the Non-U.S. Holder’s conduct of a U.S. trade or business (and, if required by an applicable income tax treaty, is attributable to a “permanent establishment” or “fixed base” maintained by the Non-U.S. Holder in the United States); or

•        the Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are met.

Gain realized by a Non-U.S. Holder described in the first bullet point above generally will be subject to U.S. federal income tax in the same manner as a U.S. Holder (but without regard to the surtax on net investment income discussed above). In addition, under certain circumstances, gain that is effectively connected with a corporate Non-U.S. Holder’s conduct of a U.S. trade or business may be subject to an additional “branch profits tax” at the rate of 30% (or a lower applicable treaty rate, provided certain certification requirements are met). Gain realized by a Non-U.S. Holder described in the second bullet point above generally will be subject to tax at a rate of 30% (or a lower applicable treaty rate, provided certain certification requirements are met) to the extent of the excess of such holder’s U.S.-source capital gains during the tax year over U.S.-source capital losses during such tax year.

To the extent that the amount realized on any sale, exchange, redemption, retirement or other taxable disposition of the notes is attributable to accrued but unpaid interest, such amount will be treated as interest as described above under “— Interest.”

Backup Withholding and Information Reporting

In certain circumstances, a Non-U.S. Holder may be subject to information reporting and backup withholding (currently at a rate of 24%) with respect to interest on the notes and the proceeds received upon the sale or other disposition of such notes (including a redemption or retirement), unless such Non-U.S. Holder certifies its non-U.S. status under penalty of perjury on a properly executed IRS Form W-8BEN or W-8BEN-E (or appropriate successor form), as applicable, or otherwise establishes and satisfies the requirements of an exemption.

Backup withholding is not an additional tax. Non-U.S. Holders generally may use amounts withheld as a credit against their U.S. federal income tax liability or may claim a refund as long as they timely provide certain information to the IRS. Non-U.S. Holders should consult their own tax advisors regarding the application of backup withholding in their particular circumstances, the availability of an exemption from information reporting and backup withholding, and the procedure for obtaining such an exemption, if available.

CERTAIN UNITED KINGDOM TAX CONSIDERATIONS

The following summary is of a general nature and applies only to persons who are the beneficial owners of the notes. It is a non-exhaustive summary of current law and practice in the United Kingdom as at the date of this prospectus supplement relating to United Kingdom stamp duty and the United Kingdom withholding tax treatments of payments in respect of the notes. It does not deal with any other aspect of the United Kingdom taxation treatment of acquiring, holding or disposing of the notes. Some aspects may not apply to certain classes of persons (such as dealers, collective investment schemes and persons connected with the Issuer), to whom special rules may apply. The United Kingdom tax treatment of holders of the notes depends on their individual circumstances and may be subject to change in the future, possibly with retrospective effect. This summary is not intended to be, nor should it be construed to be, legal or tax advice. Holders of the notes who may be subject to tax in a jurisdiction other than the United Kingdom or who may be unsure as to their tax position should seek their own professional advice.

Investors should also note that the appointment by an investor, or any person through which an investor holds notes, of a custodian, collection agent or similar person in relation to such notes in any jurisdiction may have tax implications. Investors should consult their own tax advisors in relation to the tax consequences for them of any such appointment.

Interest on the Notes

Payment of Interest on the Notes

Payments of interest on the notes may be made without withholding or deduction for or on account of United Kingdom income tax provided that the notes are and remain listed and admitted to trading on a “recognised stock exchange” within the meaning of section 1005 of the Income Tax Act 2007. The New York Stock Exchange, to which application will be made to have the notes listed, is a recognised stock exchange for those purposes. Provided, therefore, that the notes are and remain so listed and admitted to trading, interest on the notes will be payable by the Issuer without withholding or deduction for or on account of United Kingdom income tax.

If the notes are not or cease to be so listed and admitted to trading, interest will be paid by the Issuer under deduction of United Kingdom income tax at the basic rate (currently 20%) unless (i) any other exemption or relief applies, or (ii) the Issuer has received a direction to the contrary from H.M. Revenue and Customs, or HMRC, in respect of such relief as may be available pursuant to the provisions of any applicable double taxation treaty. In certain circumstances and subject to certain exceptions, the Issuer will be obliged to gross-up payments on the notes to ensure that the holders receive a net payment equal to the payment which they would have received had no such deduction or withholding for or on account of United Kingdom income tax been required. See “Description of Notes — Payment of Additional Amounts.”

The references to “interest” above mean “interest” as understood in United Kingdom tax law. The statements above do not take any account of any different definitions of “interest” or “principal” which may prevail under any other law or which may be created by the terms and conditions of the notes or any related documentation.

Holders of the notes may wish to note that, in certain circumstances, HMRC has power to obtain information (including the name and address of the beneficial owner of the interest or the amount payable on the redemption of such notes, as applicable) from any person in the United Kingdom who either pays, or credits interest to, or receives interest for the benefit of, a holder of such notes or, in the case of notes that are “deeply discounted securities” (as defined in Chapter 8 of Part 4 of the Income Tax (Trading and Other Income) Act 2005) who either pays amounts payable on the redemption of such notes to, or receives such amounts for the benefit of, a holder of such notes. Information so obtained may, in certain circumstances, be exchanged by HMRC with the tax authorities of the jurisdiction in which the holder is resident for tax purposes.

UNDERWRITING

Under the terms and subject to the conditions contained in an underwriting agreement dated the date of this prospectus supplement, the underwriters named below, for whom Barclays Bank PLC, BNP Paribas, HSBC Bank plc and J.P. Morgan Securities plc are acting as representatives, have severally agreed to purchase, and we have agreed to sell to them, severally, the principal amount of notes set forth opposite their names below:

The underwriters are offering the notes subject to their acceptance of the notes from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the notes offered by this prospectus supplement are subject to the approval of certain legal matters by counsel and to certain other conditions. The underwriters have agreed to purchase all of the notes offered by this prospectus supplement if any of the notes are purchased.

The underwriters have advised us that they initially propose to offer the notes directly to the public at the initial public offering price set forth on the cover page of this prospectus supplement. After the initial offering of the notes, the underwriters may from time to time vary the offering price and other selling terms. The following table shows the underwriting discount that we will pay to the underwriters in connection with this offering:

We have also agreed to indemnify the underwriters against certain liabilities, including liabilities under the federal securities laws, or to contribute to payments which the underwriters may be required to make in respect of any such liabilities.

In connection with the issue of the notes, the Stabilizing Manager (or any person acting on its behalf) may over-allot notes or effect transactions with a view to supporting the market price of the notes during the stabilization period at a level higher than that which might otherwise prevail. However, stabilization may not necessarily occur. Any stabilization action may begin on or after the date on which adequate public disclosure of the terms of the offer of the notes is made, and, if begun, may cease at any time, but it must end no later than the earlier of 30 calendar days after the date on which the Issuer received the proceeds of the issue or 60 calendar days after the date of the allotment of the notes. Any stabilization action or over-allotment must be conducted by the Stabilizing Manager (or any person acting on its behalf) in accordance with all applicable laws and rules.

Expenses associated with this offering to be paid by us, other than the underwriting discount, are estimated to be €             million.

The notes are a new issue of securities with no established trading market. Application will be made to have the notes listed on The New York Stock Exchange. The listing application will be subject to approval by The New York Stock Exchange. If such a listing is obtained, we will have no obligation to maintain such listing, and we may delist the notes at any time. We have been advised by the underwriters that they intend to make a market in the notes. However, the underwriters are not obligated to do so and may discontinue any market making at any time without notice. Accordingly, there can be no assurance regarding whether a trading market for the notes will develop, the ability of holders of the notes to sell their notes or the prices at which holders may be able to sell their notes.

From time to time in the ordinary course of their respective businesses, certain of the underwriters and their affiliates have engaged in and may in the future engage in commercial banking, derivatives and/or investment banking transactions with us and our affiliates for which they have received, or will receive customary fees and reimbursement of expenses.

In addition, 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. 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, these 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.

Certain underwriters and/or their affiliates are lenders and/or agents under each of our credit facility and our term loan facility.

Certain of the underwriters are not broker-dealers registered with the SEC, and therefore may not make sales of any notes in the United States or to U.S. persons except in compliance with applicable U.S. laws and regulations. To the extent that these underwriters intend to effect sales of the notes in the United States, they will do so only through one or more U.S.-registered broker-dealers, or as otherwise permitted by applicable U.S. law.

Settlement

We currently expect delivery of the notes to occur on or about             , 2024, which will be the      business day following the date of pricing of the notes (such settlement cycle being referred to as “T+             ”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in two business days (as such term is used for purposes of Rule 15c6-1 of the Exchange Act) unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on any date prior to two business days before delivery of the notes will be required, by virtue of the fact that the notes will settle in T+            , to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement; such purchasers should consult their own advisors in this regard.

Omnicom Group Inc.

Omnicom Group Inc., a New York corporation formed in 1986, through its branded networks and agencies provides advertising, marketing and corporate communications services to over 5,000 clients in more than 70 countries.

Omnicom Group Inc. is a strategic holding company providing advertising, marketing and corporate communications services to clients through its branded networks and agencies around the world. Omnicom Group operates in a highly competitive industry and competes against other global, national and regional advertising and marketing services companies, as well as technology, social media and professional services companies. The proliferation of media channels, including the rapid development and integration of interactive technologies and media, has fragmented consumer audiences targeted by Omnicom Group’s clients. These developments make it more complex for marketers to reach their target audiences in a cost-effective way, causing them to turn to global service providers such as Omnicom Group for a customized mix of advertising and marketing services designed to optimize their total marketing expenditure.

On a global, pan-regional and local basis, our branded networks and agencies operate in all major markets and provide services in the following fundamental disciplines: advertising, customer relationship management, or CRM, public relations, and healthcare. Advertising includes creative services, as well as strategic media planning and buying and data analytics services. Public relations services include corporate communications, crisis management, public affairs and media and media relations services. Healthcare includes advertising and media services to global healthcare clients. In an effort to better capture the expanding scope of our services, effective January 1, 2021, we realigned the classification of certain services primarily within our CRM Consumer Experience discipline. As a result, our CRM discipline has been reclassified into four categories: CRM Precision Marketing, which includes our precision marketing and digital/direct marketing agencies; CRM Commerce and Brand Consulting that is primarily comprised of Omnicom Commerce Group, including our shopper marketing businesses, and our Brand Consulting agencies; CRM Experiential, which includes our experiential marketing agencies and events businesses; and CRM Execution & Support, which includes field marketing, merchandising and point of sale, as well as other specialized marketing and custom communications services. Our business model was built and continues to evolve around our clients. While our networks and agencies operate under different names and frame their ideas in different disciplines, we organize our services around our clients. Our fundamental business principle is that our clients’ specific marketing requirements are the central focus of how we structure our service offerings and allocate our resources. This client-centric business model requires that multiple agencies within Omnicom collaborate in formal and informal virtual client networks utilizing our key client matrix organization structure. This collaboration allows us to cut across our internal organizational structures to execute our clients’ marketing requirements in a consistent and comprehensive manner. We use our client-centric approach to grow our business by expanding our service offerings to existing clients, moving into new markets and obtaining new clients. In addition, we pursue selective acquisitions of complementary companies with strong entrepreneurial management teams that typically currently serve or could serve our existing clients.

Driven by our clients’ continuous demand for more effective and efficient marketing activities, we strive to provide an extensive range of advertising, marketing and corporate communications services through various client-centric networks that are organized to meet specific client objectives. These services include, among others, advertising, brand consulting, content marketing, corporate social responsibility consulting, crisis communications, custom publishing, data analytics, database management, digital/direct marketing, digital transformation, entertainment marketing, experiential marketing, field marketing, financial/corporate business-to-business advertising, graphic arts/digital imaging, healthcare marketing and communications, instore design, interactive marketing, investor relations, marketing research, media planning and buying, merchandising and point of sale,

mobile marketing, multi-cultural marketing, non-profit marketing, organizational communications, package design, product placement, promotional marketing, public affairs, public relations, retail marketing, sales support, search engine marketing, shopper marketing, social media marketing and sports and event marketing.

DESCRIPTION OF U.S. DEBT SECURITIES

General

The description below of the general terms of the U.S. debt securities will be supplemented by the more specific terms of a particular series in a prospectus supplement. As used in this “Description of U.S. Debt Securities,” the term “debt securities” refers to the senior and subordinated debt securities that Omnicom Group Inc. may offer from time to time, and the terms “Issuer,” “we,” “us” and “our” refer to Omnicom Group Inc., unless the context otherwise requires or indicates.

The debt securities will be unsecured obligations of Omnicom Group Inc. and will be either senior or subordinated debt. We will issue the debt securities under the base indenture, dated as of February 21, 2021, between us and Deutsche Bank Trust Company Americas, as trustee (as supplemented, amended or otherwise modified, the “Omnicom Group Indenture”).

We have summarized the material provisions of the Omnicom Group Indenture below. The Omnicom Group Indenture has been filed as an exhibit to the registration statement of which this prospectus is a part and you should read the Omnicom Group Indenture for provisions that may be important to you.

In addition, the material specific financial, legal and other terms, as well as any material U.S. federal income tax consequences, of a particular series of debt securities will be described in the prospectus supplement relating to that series of debt securities. The prospectus supplement may or may not modify the general terms found in this prospectus and will be filed with the SEC. For a description of the terms of a particular series of debt securities, you should read both this prospectus and the prospectus supplement relating to that particular series.

The Omnicom Group Indenture provides that our debt securities may be issued in one or more series, with different terms, in each case as authorized from time to time by us. The Omnicom Group Indenture also gives us the ability to reopen a previous issue of a series of debt securities and issue additional debt securities of that series or establish additional terms for that series of debt securities. The Omnicom Group Indenture does not limit the amount of debt securities or other unsecured debt which we may issue.

Neither the senior debt securities nor the subordinated debt securities will be secured by any of our property or assets. Thus, by owning a debt security, you are one of our unsecured creditors.

In addition to the following description of the debt securities, you should refer to the detailed provisions of the Omnicom Group Indenture.

If material, federal income tax consequences and other special considerations applicable to any debt securities issued by the Issuer at a discount will be described in the applicable prospectus supplement.

The debt securities will represent direct, unsecured, general obligations of the Issuer and:

•        may rank equally with other unsubordinated debt or may be subordinated to other debt the Issuer has or may incur;

•        may be issued in one or more series with the same or various maturities;

•        may be issued at a price of 100% of their principal amount or at a premium or discount; and

•        may be represented by one or more global notes registered in the name of a designated depository’s nominee, and if so, beneficial interests in the global note will be shown on and transfers will be made only through records maintained by the designated depository and its participants.

Omnicom Group Inc. is a holding company. As a result, the debt securities issued under the Omnicom Group Indenture will effectively be subordinated to all existing and future obligations of Omnicom Group Inc.’s operating subsidiaries, including trade payables, and to Omnicom Group Inc.’s obligations that are secured, to the extent of the security.

The aggregate principal amount of debt securities that the Issuer may authenticate and deliver is unlimited. You should refer to the applicable prospectus supplement for the following terms of the debt securities of the series with respect to which that prospectus supplement is being delivered:

•        the title of the debt securities;

•        ranking of the specific series of debt securities relative to other outstanding indebtedness, including subsidiaries’ debt;

•        whether the debt securities will be senior or subordinated debt;

•        if the debt securities are subordinated, the aggregate amount of outstanding indebtedness, as of a recent date, that is senior to the subordinated securities, and any limitation on the issuance of additional senior indebtedness;

•        the percentage of the principal amount at which the debt securities will be sold and, if applicable, the method of determining the price;

•        any limit on the aggregate principal amount of the debt securities;

•        the maturity date or dates;

•        the interest rate;

•        the manner in which the amounts of payment of principal of or interest, if any, on the securities of the series will be determined, if such amounts may be determined by reference to an index based on a currency or currencies or by reference to a commodity, commodity index, stock exchange index or financial index;

•        the date or dates from which any interest will accrue, or how such date or dates will be determined, and the interest payment date or dates and any related record dates;

•        the location where payments on the debt securities will be made;

•        the terms and conditions on which the debt securities may be redeemed at the option of the Issuer;

•        the terms and conditions on which the debt securities may be repurchased by the Issuer at the option of the holders thereof;

•        any obligation of the Issuer to redeem, purchase or repay the debt securities pursuant to sinking fund provisions;

•        any obligation of the Issuer to redeem, purchase or repay the debt securities at the option of a holder upon the happening of any event and the terms and conditions of redemption, purchase or repayment;

•        if other than denominations of $2,000 and integral multiples of $1,000 in excess thereof, the denominations in which debt securities may be issued;

•        whether the debt securities will be issuable as global securities;

•        if other than the principal amount, the portion of the principal amount of the debt securities payable if the maturity is accelerated;

•        the provisions relating to any security provided for the debt securities;

•        any events of default not described in “Events of Default” below;

•        the terms and conditions on which the debt securities may be exchanged or converted into common stock or preferred stock of Omnicom Group Inc.;

•        the form and terms of any guarantee of or security for the debt securities;

•        any depositories, interest rate calculation agents or other agents;

•        any material provisions of the Omnicom Group Indenture described in this prospectus that do not apply to the debt securities; and

•        any other terms of the debt securities not inconsistent with the provisions of the Omnicom Group Indenture.

The terms on which a series of debt securities may be convertible into or exchangeable for common stock or preferred stock of Omnicom Group Inc. will be set forth in the prospectus supplement relating to such series. Such terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at the option of the Issuer. The terms may include provisions pursuant to which the number of shares of common stock or other securities of Omnicom Group Inc. to be received by the holders of such series of debt securities may be adjusted.

The debt securities will be issued only in registered form. Debt securities of a series will either be global securities registered in book-entry form, or a physical (paper) certificate issued in definitive, or certificated, registered form. Procedures relating to global securities are described below under “Book-Entry Procedures and Settlement.” Unless otherwise provided in the applicable prospectus supplement, debt securities denominated in United States dollars will be issued only in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The prospectus supplement relating to offered securities denominated in a foreign or composite currency will specify the denomination of the offered securities.

Debt securities represented by a paper certificate may be presented for exchange or transfer at the office of the Registrar. Holders will not have to pay any service charge for any registration of transfer or exchange of their certificates, but the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with such registration of transfer.

Payment and Paying Agents

Distributions on the debt securities other than those represented by global notes will be made in the designated currency against surrender of the debt securities at the principal office of the paying agent. Payment will be made to the registered holder at the close of business on the record date for such payment.

Interest payments will be made at the principal corporate trust office of the trustee in New York City, or by a check mailed to the holder at his or her registered address. Payments in any other manner will be specified in the prospectus supplement.

Book-Entry Procedures and Settlement

The debt securities will be issued in book-entry form only and represented by one or more global securities registered in the name of, and deposited with a custodian for, The Depository Trust Company, or DTC, or its nominee. DTC or its nominee will be the sole registered holder of the debt securities for all purposes under the Omnicom Group Indenture. Owners of beneficial interests in the debt securities represented by the global securities will hold their interests pursuant to the procedures and practices of DTC. As a result, beneficial interests in these securities will be shown on, and may only be transferred through, records maintained by DTC and its direct and indirect participants and any such interest may not be exchanged for certificated securities, except in limited circumstances. Owners of beneficial interests must exercise any rights in respect of their interests, in accordance with the procedures and practices of DTC. Beneficial owners will not be holders and will not be entitled to any rights provided to the holders of debt securities under the global securities or the Omnicom Group Indenture.

The Issuer and the trustee, and any of their respective agents, may treat DTC as the sole holder and registered owner of the global securities under the terms of the Omnicom Group Indenture.

Optional Redemption

Unless an applicable prospectus supplement specifies otherwise, the debt securities will not be redeemable. In the event the debt securities are redeemable, the debt securities will be redeemable, as a whole or in part, at the Issuer’s option, at any time or from time to time, upon mailed notice (or electronic notice, as applicable) to the registered address of each holder of debt securities at least 15 days but not more than 60 days prior to the redemption. The redemption price will be equal to the greater of (1) 100% of the principal amount of the debt

securities to be redeemed and (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) on such debt securities discounted to the date of redemption, on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months), at a rate equal to the sum of the applicable Treasury Rate (as defined below) plus a make whole spread, which will be specified in the applicable prospectus supplement, plus accrued and unpaid interest thereon to the redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Reference Treasury Dealer (as defined below) as having a maturity comparable to the remaining term of the debt securities, 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 debt securities.

“Comparable Treasury Price” means, with respect to any redemption date, the Reference Treasury Dealer Quotations (as defined below) for that redemption date.

“Reference Treasury Dealer” means each of any three primary U.S. Government securities dealer selected by us, and their respective successors.

“Reference Treasury Dealer Quotations” means, with respect to the Reference Treasury Dealer and any redemption date, the average, as determined by the Issuer, 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 Issuer by the Reference Treasury Dealer at 3:30 p.m., New York City time, on the third business day preceding that redemption date.

“Remaining Scheduled Payments” means the remaining scheduled payments of principal of and interest on the debt securities that but for the redemption would be due after the related redemption date, not including any portion of such interest payment accrued as of such redemption date. If that redemption date is not an interest payment date with respect to the debt securities, the amount of the next succeeding scheduled interest payment on the debt securities will be reduced by the amount of interest accrued on the debt securities to such redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity (computed as of the third business day immediately preceding that redemption date) of the Comparable Treasury Issue (as defined below), assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date.

On and after the redemption date, interest will cease to accrue on the debt securities or any portion of the debt securities called for redemption (unless we default in the payment of the redemption price and accrued interest).

The Issuer may not consolidate with or merge into, or convey, transfer or lease its properties and assets as an entirety or substantially as an entirety to, any person, referred to as a “successor person,” unless:

•        either (a) the Issuer is the successor person or (b) the successor person is an entity organized under the laws of the United States;

•        the successor person expressly assumes the Issuer’s obligations with respect to the debt securities and the Omnicom Group Indenture;

•        immediately after giving effect to the transaction, no event of default, and no event which, after notice or lapse of time or both, would become an event of default, shall have occurred and be continuing; and

•        the Issuer or the successor person has delivered to the trustee the certificates and opinions required under the Omnicom Group Indenture.

Modification of the Omnicom Group Indenture

The Omnicom Group Indenture provides that the Issuer and the trustee may enter into supplemental indentures without obtaining the consent of any holder of debt securities:

•        to cure any ambiguity, defect or inconsistency;

•        to comply with the Omnicom Group Indenture’s provisions regarding successor corporations;

•        to comply with any requirements of the SEC in connection with the qualification of the Omnicom Group Indenture under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”);

•        to provide for global securities in addition to or in place of certificated debt securities;

•        to add to, change or eliminate any of the provisions of the Omnicom Group Indenture with respect to any series of debt securities; although no such addition, change or elimination may apply to any series of debt security created prior to the execution of such amendment and entitled to the benefit of such provision, nor may any such amendment modify the rights of a holder of any such debt security with respect to such provision, unless the amendment becomes effective only when there is no outstanding debt security of any series created prior to such amendment and entitled to the benefit of such provision;

•        in the case of subordinated debt securities, to make any change in the provisions of the Omnicom Group Indenture relating to subordination that would limit or terminate the benefits available to any holder of senior indebtedness under such provisions (but only if each such holder of senior indebtedness consents to such change);

•        to make any change that does not materially adversely affect in any material respect the legal rights of any holder; or

•        to establish additional series of debt securities as permitted by the Omnicom Group Indenture.

The Omnicom Group Indenture provides that the Issuer and the trustee may, with the consent of the holders of at least a majority in aggregate principal amount of the debt securities of a series, modify the Omnicom Group Indenture or the rights of the holders of the securities of the series to be affected. No modifications may, without the consent of the holder of each security affected, be made that, as to any non-consenting holders:

•        reduce the percentage of securities whose holders need to consent to the modification;

•        reduce the rate or change the time of payment of interest on the securities;

•        reduce the principal amount of or the premium, if any, on the securities;

•        change the fixed maturity of any of the securities;

•        reduce the amount of, or postpone the date fixed for, the payment of any sinking fund;

•        reduce the principal amount payable upon acceleration of the maturity of any securities issued originally at a discount;

•        in the case of any subordinated debt security or coupons appertaining thereto, make any change in the provisions of the Omnicom Group Indenture relating to subordination that adversely affects the rights of any holder under such provisions;

•        waive a default in the payment of the principal amount of, the premium, if any, or any interest on the securities;

•        change the currency in which any of the securities are payable;

•        impair the right to sue for the enforcement of any payment on or after the maturity of the securities; or

•        waive a redemption payment with respect to the securities.

Events of Default

The Omnicom Group Indenture provides that events of default regarding any series of debt securities include:

•        failure to pay required interest on any debt security of such series for 30 days;

•        failure to pay principal, other than a scheduled installment payment, or premium, if any, on any debt security of the series when due;

•        failure to make any required deposit of any sinking fund payment when due;

•        failure to perform for 60 days after notice any other covenant in the Omnicom Group Indenture (other than a covenant included in the Omnicom Group Indenture solely for the benefit of a series of debt securities other than such series);

•        (A) the Issuer’s failure to make any payment by the end of any applicable grace period after maturity of its indebtedness, which term as used in the Omnicom Group Indenture means obligations (other than nonrecourse obligations) of the Issuer for borrowed money or evidenced by bonds, debentures, notes or similar instruments in an amount (taken together with amounts in (B)) in excess of $100 million and continuance of such failure, or (B) the acceleration of its indebtedness in an amount (taken together with the amounts in (A)) in excess of $100 million because of a default with respect to such indebtedness without such indebtedness having been discharged or such acceleration having been cured, waived, rescinded or annulled in case of (A) or (B) above, for a period of 30 days after written notice to the Issuer by the trustee or to the Issuer and the trustee by the holders of not less than 25% in aggregate principal amount of the notes then outstanding; however, if any such failure or acceleration referred to in (A) or (B) above shall cease or be cured or be waived, rescinded or annulled in accordance with the terms of the applicable debt security, then the event of default by reason thereof shall be deemed not to have occurred;

•        certain events of bankruptcy or insolvency, whether voluntary or not; or

•        any other event of default described in the prospectus supplement of such series of debt securities.

If an event of default (other than the bankruptcy provision) regarding debt securities of any series issued under the Omnicom Group Indenture should occur and be continuing, either the trustee or the holders of 25% in the principal amount of outstanding debt securities of such series may declare each debt security of that series due and payable. If a bankruptcy event occurs, the principal of and accrued and unpaid interest on the debt securities of such series shall immediately become due and payable without any declaration or other act on the part of the trustee or the holders of the debt securities of such series. The holders of a majority in principal amount of debt securities of such series may rescind any other declaration or acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing events of default have been cured or waived (other than nonpayment of principal or interest that has become due solely as a result of acceleration). The Issuer is required to file annually with the trustee a statement of an officer as to the fulfillment by the Issuer of its obligations under the Omnicom Group Indenture during the preceding year.

Holders of a majority in principal amount of the outstanding debt securities of any series are entitled to control certain actions of the trustee under the Omnicom Group Indenture. Holders of a majority in principal amount of the outstanding debt securities of any series also will be entitled to waive past defaults regarding the series, except for a default in payment of principal, premium or interest or a default in a covenant or provision which may not be modified or amended without the consent of each holder of a debt security of the affected series. The trustee generally may not be ordered or directed by any of the holders of debt securities to take any action, unless one or more of the holders shall have offered to the trustee security or indemnity satisfactory to it.

If an event of default occurs and is continuing regarding a series of debt securities, the trustee may use any sums that it holds under the Omnicom Group Indenture for its own reasonable compensation and expenses incurred prior to paying the holders of debt securities of such series.

Before any holder of any series of debt securities may institute action for any remedy, except payment on the holder’s debt security when due, the holders of not less than 25% in principal amount of the debt securities of that series outstanding must request the trustee to take action. Holders must also offer and give the trustee security and indemnity satisfactory to it against liabilities incurred by the trustee for taking such action.

Defeasance

The Omnicom Group Indenture provides that the Issuer may specify with respect to any series of debt securities that after the Issuer has deposited with the trustee, cash or government securities, in trust for the benefit of the holders sufficient to pay the principal of, premium, if any, and interest on and any mandatory sinking fund payments in respect of the debt securities of such series when due, then the Issuer:

•        will be deemed to have paid and satisfied its obligations on all outstanding debt securities of such series, which is known as “defeasance and discharge”; or

•        will cease to be under any obligation, other than to pay when due the principal of, premium, if any, and interest on and any mandatory sinking fund payments in respect of such debt securities, relating to the debt securities of such series, which is known as “covenant defeasance.”

In each case, the Issuer must also deliver to the trustee an opinion of counsel to the effect that the holders of the debt securities of such series will have no federal income tax consequences as a result of such deposit.

In addition, the Omnicom Group Indenture provides that if the Issuer chooses to have the defeasance and discharge provision applied to the subordinated debt securities, the subordination provisions of the Omnicom Group Indenture will become ineffective upon full defeasance of the subordinated debt securities.

When there is a defeasance and discharge, with limited exceptions, (1) the Omnicom Group Indenture will no longer govern the debt securities of such series, (2) the Issuer will no longer be liable for payment, and (3) the holders of the debt securities will be entitled only to the deposited funds. When there is a covenant defeasance, however, the Issuer will continue to be obligated to make payments when due if the deposited funds are not sufficient.

Subordination

Debt securities of a series, and any guarantees, may be subordinated, which we refer to as subordinated debt securities, to senior indebtedness (as defined in the applicable prospectus supplement) to the extent set forth in the prospectus supplement relating thereto. To the extent we conduct operations through subsidiaries, the holders of debt securities (whether or not subordinated debt securities) will be structurally subordinated to the creditors of our subsidiaries except to the extent such subsidiary is a guarantor of such series of debt securities.

Further Issues

The Issuer may from time to time, without notice to or the consent of the registered holders of a series of debt securities, create and issue further debt securities of any such series ranking equally with the debt securities of the corresponding series in all respects (or in all respects other than the payment of interest accruing prior to the issue date of such further debt securities or except for the first payment of interest following the issue date of such further debt securities). Such further debt securities may be consolidated and form a single series with the debt securities of the corresponding series and have the same terms as to status, redemption or otherwise as the debt securities of the corresponding series.

Concerning the Trustee

The trustee may engage in transactions with, or perform services for, the Issuer and affiliates of the Issuer in the ordinary course of business. The trustee will perform only those duties that are specifically set forth in the Omnicom Group Indenture unless an event of default under the Omnicom Group Indenture occurs and is continuing. In case an event of default occurs and is continuing, the trustee will exercise the same degree of care and skill as a prudent individual would exercise in the conduct of his or her own affairs.

Applicable Law

The debt securities will be governed by, and construed in accordance with, the laws of the State of New York. The Omnicom Group Indenture is governed by the laws of the State of New York.

DESCRIPTION OF INTERNATIONAL DEBT SECURITIES

General

The description below of the general terms of the international debt securities will be supplemented by the more specific terms of a particular series in a prospectus supplement. As used in this “Description of International Debt Securities,” the term “debt securities” refers to the senior and subordinated debt securities that Omnicom Finance Holdings or Omnicom Capital Holdings may offer from time to time, and the terms “Issuer,” “we,” “us” and “our” refer to one of Omnicom Finance Holdings or Omnicom Capital Holdings, unless the context otherwise requires or indicates.

The debt securities will be either senior or subordinated debt. Omnicom Finance Holdings or Omnicom Capital Holdings will enter into an indenture with Deutsche Bank Trust Company Americas, as trustee, and with Omnicom Group, Inc., as guarantor, the forms of which are filed as exhibits to the registration statement of which this prospectus forms a part (the “International Indenture”).

We have summarized the material provisions of the International Indenture below.

In addition, the material specific financial, legal and other terms, of a particular series of debt securities will be described in the prospectus supplement relating to that series of debt securities. The prospectus supplement may or may not modify the general terms found in this prospectus and will be filed with the SEC. For a description of the terms of a particular series of debt securities, you should read both this prospectus and the prospectus supplement relating to that particular series.

The International Indenture will provide that our debt securities may be issued in one or more series, with different terms, in each case as authorized from time to time by us. The International Indenture will also give us the ability to reopen a previous issue of a series of debt securities and issue additional debt securities of that series or establish additional terms for that series of debt securities. The International Indenture will not limit the amount of debt securities or other unsecured debt which we may issue.

Neither the senior debt securities nor the subordinated debt securities will be secured by any of our property or assets. Thus, by owning a debt security, you are one of our unsecured creditors.

In addition to the following description of the debt securities, you should refer to the detailed provisions of the International Indenture.

The material United States federal income tax and United Kingdom income and corporation tax consequences and other special considerations applicable to any debt securities issued by the Issuer at a discount will be described in the applicable prospectus supplement.

The debt securities will represent direct, unsecured, general obligations of the Issuer and:

•        may rank equally with other unsubordinated debt or may be subordinated to other debt the Issuer has or may incur;

•        may be issued in one or more series with the same or various maturities;

•        may be issued at a price of 100% of their principal amount or at a premium or discount; and

•        may be represented by one or more global notes registered in the name of a designated depository’s nominee, and if so, beneficial interests in the global note will be shown on and transfers will be made only through records maintained by the designated depository and its participants.

Omnicom Group Inc. is a holding company and Omnicom Finance Holdings and Omnicom Capital Holdings are finance subsidiaries. As finance subsidiaries, Omnicom Finance Holdings’ and Omnicom Capital Holdings’ assets consist of their investments in several wholly owned finance companies that function as treasury centers, which provide funding for various operating companies in EMEA, Australia and Asia-Pacific. The finance companies’ assets consist of intercompany loans that they make or have made to the operating companies in their region and the related interest receivables. The debt securities issued under the International Indenture will effectively be subordinated to the Issuer’s obligations that are secured, to the extent of the security.

Omnicom Finance Holdings’ and Omnicom Capital Holdings’ obligations in respect of any debt securities will be guaranteed by Omnicom Group Inc. The guarantee of the debt securities issued under the International Indenture will effectively be subordinated to Omnicom Group Inc.’s obligations that are secured, to the extent of the security, and to all existing and future obligations of Omnicom Group Inc.’s operating subsidiaries, including trade payables.

The aggregate principal amount of debt securities that the Issuer may authenticate and deliver is unlimited. You should refer to the applicable prospectus supplement for the following terms of the debt securities of the series with respect to which that prospectus supplement is being delivered:

•        the title of the debt securities;

•        ranking of the specific series of debt securities relative to other outstanding indebtedness, including subsidiaries’ debt;

•        whether the debt securities will be senior or subordinated debt;

•        if the debt securities are subordinated, the aggregate amount of outstanding indebtedness, as of a recent date, that is senior to the subordinated securities, and any limitation on the issuance of additional senior indebtedness;

•        the percentage of the principal amount at which the debt securities will be sold and, if applicable, the method of determining the price;

•        any limit on the aggregate principal amount of the debt securities;

•        the maturity date or dates;

•        the interest rate;

•        the terms and conditions on which the debt securities may be repurchased by the Issuer at the option of the holders thereof;

•        any obligation of the Issuer to redeem, purchase or repay the debt securities pursuant to sinking fund provisions;

•        any obligation of the Issuer to redeem, purchase or repay the debt securities at the option of a holder upon the happening of any event and the terms and conditions of redemption, purchase or repayment;

•        if other than minimum denominations of $200,000 and multiples of $1,000 in excess thereof, the minimum denominations in which debt securities may be issued;

•        whether the debt securities will be issuable as global securities;

•        if other than the principal amount, the portion of the principal amount of the debt securities payable if the maturity is accelerated;

•        the provisions relating to any security provided for the debt securities;

•        any events of default not described in “Events of Default” below;

•        the terms and conditions on which the debt securities may be exchanged or converted into common stock of Omnicom Group Inc.;

•        any depositories, interest rate calculation agents or other agents;

•        if the debt securities will be issued in the form of one or more book-entry securities, the name of the depository or its nominee and the circumstances under which the book-entry security may be transferred or exchanged to someone other than the depository or its nominee;

•        any material provisions of the International Indenture described in this prospectus that do not apply to the debt securities;

•        any listing on a securities exchange;

•        the currency or currencies in which payment of the principal of, premium, if any, and interest on, the debt securities shall be payable; and

•        any other terms of the debt securities not inconsistent with the provisions of the International Indenture.

The terms on which a series of debt securities may be convertible into or exchangeable for common stock of Omnicom Group Inc. will be set forth in the prospectus supplement relating to such series. Such terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at the option of the Issuer. The terms may include provisions pursuant to which the number of shares of common stock of Omnicom Group Inc. to be received by the holders of such series of debt securities may be adjusted.

The debt securities will be issued only in registered form. Debt securities of a series will either be global securities registered in book-entry form, or a physical (paper) certificate issued in definitive, or certificated, registered form. Procedures relating to global securities are described below under “Book-Entry; Delivery and Form; Global Securities.” Unless otherwise provided in the applicable prospectus supplement, debt securities denominated in United States dollars will be issued only in minimum denominations of $200,000 and integral multiples of $1,000 in excess thereof. The prospectus supplement relating to offered securities denominated in a foreign or composite currency will specify the denomination of the offered securities.

Debt securities represented by a paper certificate may be presented for exchange or transfer at the office of the Registrar. Holders will not have to pay any service charge for any registration of transfer or exchange of their certificates, but the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with such registration of transfer.

Guarantee

Omnicom Group Inc. will fully and unconditionally guarantee the full and punctual payment of principal of and premium, if any, and interest on the debt securities on a senior unsecured basis, when and as the same become due and payable, whether on a maturity date, by declaration of acceleration, upon redemption, repurchase or otherwise, and all other obligations of Omnicom Finance Holdings and Omnicom Capital Holdings under the International Indenture.

Payment and Paying Agents

Distributions on the debt securities other than those represented by global notes will be made in the designated currency against surrender of the debt securities at the principal office of the paying agent. Payment will be made to the registered holder at the close of business on the record date for such payment.

Interest payments will be made at the principal corporate trust office of the trustee in New York City, or by a check mailed to the holder at his or her registered address. Payments in any other manner will be specified in the prospectus supplement.

Book-Entry; Delivery and Form; Global Securities

The debt securities will be issued in book-entry form only and evidenced by a global security in registered form, and, in the case of debt securities denominated in Dollars, with a CUSIP, registered in the name of a nominee for DTC, and, in the case of debt securities denominated in another currency, with an ISIN and Common Code, registered in the name of a nominee for, and deposited with a common depositary on behalf of, Euroclear Bank S.A./N.V. (“Euroclear”) and Clearstream Banking, S.A., Luxembourg (“Clearstream, Luxembourg”). Beneficial interests in a global security may be held only through DTC, Euroclear or Clearstream, Luxembourg, as the case may be, at any time.

Except in the limited circumstances, owners of beneficial interests in a global security will not be entitled to receive physical delivery of certificated debt securities in definitive form. The debt securities are not issuable in bearer form.

Upon the issuance of the global securities and their deposit with or on behalf of DTC, Euroclear, Clearstream, Luxembourg and/or the common depositary, as the case may be, DTC, Euroclear, Clearstream, Luxembourg and/or the common depositary or the relevant nominee will credit, on its book-entry registration and transfer system, the principal amounts of debt securities represented by the global securities to the accounts of participating institutions that have accounts with DTC, Euroclear, Clearstream, Luxembourg, the common depositary and/or the relevant nominee. Ownership of beneficial interests in the global securities will be limited to participating institutions or their clients. DTC, Euroclear, Clearstream, Luxembourg, the common depositary and/or the relevant nominee will keep records of the ownership and transfer of beneficial interests in the global securities by participating institutions. Participating institutions will keep records of the ownership and transfer of beneficial interests by their clients. The laws of some jurisdictions may require that purchasers of debt securities receive physical certificates, which may impair a holder’s ability to transfer its beneficial interests in global securities.

DTC, Euroclear, Clearstream, Luxembourg, the common depositary and/or the relevant nominee as the registered owner of a global security will be considered the sole owner of all of debt securities represented by the relevant global security for all purposes under the International Indenture. Generally, if a holder owns beneficial interests in a global security, that holder will not be entitled to have debt securities registered in that holder’s own name, and that holder will not be entitled to receive a certificate representing that holder’s ownership. Accordingly, if a holder owns a beneficial interest in a global security, the holder must rely on DTC, Euroclear, Clearstream, Luxembourg, the common depositary and/or the relevant nominee and, if applicable, the participating institution of which that holder is a client to exercise the rights of that holder under the International Indenture.

Optional Redemption

Unless an applicable prospectus supplement specifies otherwise, the debt securities will not be redeemable, except as provided under “— Redemption Upon Changes in Withholding Taxes” below. In the event the debt securities are redeemable, the debt securities will be redeemable, as a whole or in part, at the Issuer’s option, at any time or from time to time, upon mailed notice (or electronic notice, as applicable) to the registered address of each holder of debt securities at least 15 days but not more than 60 days prior to the redemption. The terms of such redemption will be set forth in the applicable prospectus supplement.

Redemption Upon Changes in Withholding Taxes

Unless otherwise provided in the applicable prospectus supplement, Omnicom Finance Holdings or Omnicom Capital Holdings, as applicable, may redeem all, but not less than all, of the debt securities of any series at a redemption price equal to 100% of the principal amount thereof, together with accrued interest, if any, to the redemption date and Additional Amounts (as defined below under “Payment of Additional Amounts”), if any, under the following conditions:

•        if there is an amendment to, or change in, the laws, regulations, rulings or treaties of the United Kingdom, the United States or other jurisdiction in which Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc. or, in each case, any successor thereof (including a successor person formed by a consolidation with Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc., into which Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc. is merged, or that acquires or leases all or substantially all of the property and assets of

Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc.) may be incorporated, organized, or otherwise resident for tax purposes, or engaged in business for tax purposes, as applicable, or any political subdivision thereof or therein having the power to tax, or any jurisdiction from or through which payment is made by or on behalf of Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc. (a “Taxing Jurisdiction”), or any change in the application or official interpretation of such laws, regulations, rulings or treaties, including any action taken by, or a change in published administrative practice of, a taxing authority or a holding by a court of competent jurisdiction, regardless of whether such action, change or holding is with respect to Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc.;

•        as a result of such amendment or change, Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc. becomes, or there is a substantial probability that Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc. will become, obligated to pay Additional Amounts as defined below in “Payment of Additional Amounts,” on the next payment date with respect to the debt securities of such series (but, in the case of the guarantor, only if the payment giving rise to such requirement cannot be made by Omnicom Finance Holdings or Omnicom Capital Holdings, as the case may be);

•        the obligation to pay Additional Amounts cannot be avoided through Omnicom Finance Holdings’, Omnicom Capital Holdings’ or Omnicom Group Inc.’s commercially reasonable measures, including, for the avoidance of doubt, the appointment of a new paying agent, but not including substitution of the obligor of the debt securities;

•        Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc., as the case may be,:

•        delivers to the trustee a certificate of Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc., as the case may be, stating that the obligation to pay Additional Amounts cannot be avoided by Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc., as the case may be, taking commercially reasonable measures available to it; and

•        based upon a written opinion of independent tax counsel to Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc., as the case may be, of recognized standing to the effect that Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc., as the case may be, has, or there is a substantial probability that it will become, obligated to pay Additional Amounts as a result of a change, amendment, official interpretation or application described above; and

•        following the delivery of the certificate and opinion described in the previous bullet point, Omnicom Finance Holdings or Omnicom Capital Holdings, as applicable, provides notice of redemption not less than 30 days, but not more than 60 days, prior to the date of redemption. The notice of redemption cannot be given more than 60 days before the earliest date on which Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc. would otherwise be, or there is a substantial probability that it would otherwise be, required to pay Additional Amounts.

Upon the occurrence of each of the bullet points above, Omnicom Finance Holdings or Omnicom Capital Holdings, as applicable, may redeem the debt securities of such series at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, to the redemption date.

Payment of Additional Amounts

Unless otherwise required by law, none of Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc. will deduct or withhold from payments made by Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc. under or with respect to the debt securities and the guarantee on account of any present or future taxes, duties, levies, imposts, assessments or governmental charges of whatever nature imposed or levied by or on behalf of any Taxing Jurisdiction (“Taxes”). In the event that Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc. is required to withhold or deduct any amount for or on account of any Taxes from any payment made under or with respect to any debt securities or guarantee, as the case may be, Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc., as the case may

be, will pay such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by each holder of debt securities (including Additional Amounts) after such withholding or deduction will equal the amount that such holder would have received if such Taxes had not been required to be withheld or deducted.

Additional Amounts will not be payable with respect to a payment made to a holder of debt securities or a holder of beneficial interests in global securities where such holder is subject to taxation on such payment by a relevant Taxing Jurisdiction for or on account of:

•        any Taxes that are imposed or withheld solely because such holder (or the beneficial owner for whose benefit such holder holds such debt securities) or a fiduciary, settlor, beneficiary, member, shareholder or other equity owner of, or possessor of a power over, such holder (or beneficial owner) if such holder (or beneficial owner) is an estate, trust, partnership, limited liability company, corporation or other entity:

•        is or was present or engaged in, or is or was treated as present or engaged in, a trade or business in the Taxing Jurisdiction or has or had a permanent establishment in the Taxing Jurisdiction (in each case, other than the mere fact of ownership of such debt securities, without another presence or business in such Taxing Jurisdiction);

•        has or had any present or former connection (other than the mere fact of ownership of such debt securities) with the Taxing Jurisdiction imposing such Taxes, including being or having been a national citizen or resident thereof, being treated as being or having been a resident thereof or being or having been physically present therein;

•        (in relation to payments by the guarantor only) is or was a personal holding company, a passive foreign investment company, a controlled foreign corporation, a foreign private foundation or other foreign tax exempt organization or corporation that has accumulated earnings to avoid United States federal income tax;

•        (in relation to payments by the guarantor only) is or was a “10-percent shareholder” of Omnicom Group Inc. within the meaning of Section 871(h)(3) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) or any successor provisions;

•        Taxes imposed on any holder that is not the sole beneficial owner of the debt securities, or a portion thereof, or that is a fiduciary or partnership, but only to the extent that a beneficiary or settlor with respect to the fiduciary, a beneficial owner or member of the partnership would not have been entitled to the payment of an Additional Amount had the beneficiary, settlor, beneficial owner, or member received directly its beneficial or distributive share of the payment;

•        any estate, inheritance, gift, sales, transfer, excise, personal property or similar Taxes imposed with respect to the debt securities, except as otherwise provided in the International Indenture;

•        any Taxes imposed solely as a result of the presentation of such debt securities (where presentation is required) for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever is later, except to the extent that the beneficiary or holder thereof would have been entitled to the payment of Additional Amounts had the debt securities been presented for payment on any date during such 30-day period;

•        any Taxes imposed or withheld solely as a result of the failure of such holder or any other person to comply with applicable certification, information, documentation or other reporting requirements concerning the nationality, residence, or identity of such holder or connection with any Taxing Jurisdiction by such holder, if such compliance is required by statute, regulation, ruling or administrative practice of the relevant Taxing Jurisdiction or by any applicable tax treaty to which the relevant Taxing Jurisdiction is a party as a precondition to relief or exemption from such Taxes;

•        any Taxes that are payable by any method other than withholding or deduction by Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc. or any paying agent from payments in respect of such debt securities;

•        any Taxes required to be withheld by any paying agent from any payment in respect of any debt securities if such payment can be made without such withholding by at least one other paying agent in the United States or the United Kingdom;

•        any withholding or deduction required pursuant to sections 1471 through 1474 of the Code, any regulations or agreements thereunder, official interpretations thereof, any intergovernmental agreement, or any law, rule, guidance or administrative practice implementing an intergovernmental agreement entered into in connection with such sections of the Code; or

•        any combination of the above conditions.

Each of Omnicom Finance Holdings, Omnicom Capital Holdings and Omnicom Group Inc., as applicable, also:

At least 30 days prior to each date on which any payment under or with respect to the debt securities of a series or related guarantee is due and payable, if Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc. will be obligated to pay Additional Amounts with respect to such payment, Omnicom Finance Holdings, Omnicom Capital Holdings or Omnicom Group Inc. will deliver to the trustee an officer’s certificate stating the fact that such Additional Amounts will be payable, the amounts so payable and such other information as is necessary to enable the trustee to pay such Additional Amounts to holders of such debt securities on the payment date.

In addition, Omnicom Finance Holdings and Omnicom Capital Holdings will pay any stamp, issue, registration, documentary or other similar taxes and duties, including interest, penalties and Additional Amounts with respect thereto, payable in the United Kingdom or the United States or any political subdivision or taxing authority of or in the foregoing in respect of the creation, issue, offering, enforcement, redemption or retirement of the debt securities.

The Issuer and Omnicom Group Inc. may not consolidate with or merge into, or convey, transfer or lease their respective properties and assets as an entirety or substantially as an entirety to, any person, referred to as a “successor person,” except in the case of the Issuer with, into or to Omnicom Group Inc. or any other subsidiary of Omnicom Group Inc. (provided that the successor person (if any) expressly assumes by a supplemental indenture the Issuer’s obligations on the debt securities and under the International Indenture), unless:

•        either (a) the Issuer or Omnicom Group Inc., as applicable, is the successor person or (b) the successor person is an entity organized under the laws of (i) in the case of the Issuer, the United Kingdom, any member country of the European Union or the United States or (ii) in the case of Omnicom Group Inc., the United States;

•        the Issuer or Omnicom Group Inc., as applicable, or the successor person has delivered to the trustee the certificates and opinions required under the International Indenture.

Modification of the International Indenture

The International Indenture will provide that the Issuer, Omnicom Group Inc. and the trustee may enter into supplemental indentures without obtaining the consent of any holder of debt securities:

•        to cure any ambiguity, defect or inconsistency;

•        to comply with the International Indenture’s provisions regarding successor corporations;

•        to comply with any requirements of the SEC in connection with the qualification of the International Indenture under the Trust Indenture Act;

•        to provide for global securities in addition to or in place of certificated debt securities;

•        to add to, change or eliminate any of the provisions of the International Indenture with respect to any series of debt securities; although no such addition, change or elimination may apply to any series of debt security created prior to the execution of such amendment and entitled to the benefit of such provision, nor may any such amendment modify the rights of a holder of any such debt security with respect to such provision, unless the amendment becomes effective only when there is no outstanding debt security of any series created prior to such amendment and entitled to the benefit of such provision;

•        in the case of subordinated debt securities, to make any change in the provisions of the International Indenture relating to subordination that would limit or terminate the benefits available to any holder of senior indebtedness under such provisions (but only if each such holder of senior indebtedness consents to such change);

•        to secure the debt securities of any series or any guarantee thereof;

•        to add an additional guarantor of any series of debt securities;

•        to add to the Issuer’s or the guarantor’s covenants or obligations under the International Indenture for the protection of the holders of the debt securities or surrender any right, power or option conferred by the International Indenture on the Issuer or the guarantor of the debt securities;

•        to make any change that does not materially adversely affect in any material respect the legal rights of any holder; or

•        to establish additional series of debt securities as permitted by the International Indenture.

The International Indenture will provide that the Issuer, Omnicom Group Inc. and the trustee may, with the consent of the holders of at least a majority in aggregate principal amount of the debt securities of a series, modify the International Indenture or the rights of the holders of the securities of the series to be affected. No modifications may, without the consent of the holder of each security affected, be made that, as to any non-consenting holders:

•        reduce the percentage of securities whose holders need to consent to the modification;

•        reduce the rate or change the time of payment of interest on the securities;

•        reduce the principal amount of or the premium, if any, on the securities;

•        change the fixed maturity of any of the securities;

•        reduce the amount of, or postpone the date fixed for, the payment of any sinking fund;

•        reduce the principal amount payable upon acceleration of the maturity of any securities issued originally at a discount;

•        in the case of any subordinated debt security or coupons appertaining thereto, make any change in the provisions of the International Indenture relating to subordination that adversely affects the rights of any holder under such provisions;

•        waive a default in the payment of the principal amount of, the premium, if any, or any interest on the securities;

•        change the currency in which any of the securities are payable;

•        impair the right to sue for the enforcement of any payment on or after the maturity of the securities;

•        release Omnicom Group Inc. from its obligations in respect of the guarantee of any series of debt securities or modify Omnicom Group Inc.’s obligations thereunder other than in accordance with the provisions of the International Indenture; or

•        waive a redemption payment with respect to the securities.

Events of Default

The International Indenture will provide that events of default regarding any series of debt securities will be:

•        failure to pay required interest on any debt security of such series for 30 days;

•        failure to pay principal, other than a scheduled installment payment, or premium, if any, on any debt security of the series when due;

•        failure to make any required deposit of any sinking fund payment when due;

•        failure to perform for 60 days after notice any other covenant in the International Indenture (other than a covenant included in the International Indenture solely for the benefit of a series of debt securities other than such series);

•        (A) the Issuer’s or Omnicom Group Inc.’s failure to make any payment by the end of any applicable grace period after maturity of their respective indebtedness, which term as used in this clause means obligations (other than nonrecourse obligations) of the Issuer or Omnicom Group Inc., as applicable, for borrowed money or evidenced by bonds, debentures, notes or similar instruments in an amount (taken

together with amounts in (B)) in excess of $100 million and continuance of such failure, or (B) the acceleration of their respective indebtedness in an amount (taken together with the amounts in (A)) in excess of $100 million because of a default with respect to such indebtedness without such indebtedness having been discharged or such acceleration having been cured, waived, rescinded or annulled in case of (A) or (B) above, for a period of 30 days after written notice to the Issuer and Omnicom Group Inc. by the trustee or to the Issuer, Omnicom Group Inc. and the trustee by the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series; however, if any such failure or acceleration referred to in (A) or (B) above shall cease or be cured or be waived, rescinded or annulled in accordance with the terms of the applicable indebtedness, then the event of default by reason thereof shall be deemed not to have occurred;

•        Omnicom Group Inc.’s guarantee applicable to the debt securities of that series ceases to be in full force and effect or is declared null and void or Omnicom Group Inc. denies that it has any further liability under its guarantee of such debt securities to the holders of debt securities of that series, or has given notice to such effect (other than by reason of the release of such guarantee in accordance with the International Indenture), and such condition shall have continued for a period of 30 days after written notice has been given to the Issuer and Omnicom Group Inc. by the trustee or to the Issuer, Omnicom Group Inc. and the trustee by the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series;

•        certain events of bankruptcy or insolvency, whether voluntary or not; or

•        any other event of default described in the prospectus supplement of such series of debt securities.

If an event of default (other than the bankruptcy provision) regarding debt securities of any series issued under the International Indenture should occur and be continuing, either the trustee or the holders of 25% in the principal amount of outstanding debt securities of such series may declare each debt security of that series due and payable. If a bankruptcy event occurs, the principal of and accrued and unpaid interest on the debt securities of such series shall immediately become due and payable without any declaration or other act on the part of the trustee or the holders of the debt securities of such series. The holders of a majority in principal amount of debt securities of such series may rescind any other declaration or acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing events of default have been cured or waived (other than nonpayment of principal or interest that has become due solely as a result of acceleration). The Issuer and Omnicom Group Inc. will be required to file annually with the trustee a statement of an officer as to the fulfillment by the Issuer and Omnicom Group Inc. of their respective obligations under the International Indenture during the preceding year.

Holders of a majority in principal amount of the outstanding debt securities of any series will be entitled to control certain actions of the trustee under the International Indenture. Holders of a majority in principal amount of the outstanding debt securities of any series also will be entitled to waive past defaults regarding the series, except for a default in payment of principal, premium or interest or a default in a covenant or provision which may not be modified or amended without the consent of each holder of a debt security of the affected series. The trustee generally may not be ordered or directed by any of the holders of debt securities to take any action, unless one or more of the holders shall have offered to the trustee security or indemnity satisfactory to it.

If an event of default occurs and is continuing regarding a series of debt securities, the trustee may use any sums that it holds under the International Indenture for its own reasonable compensation and expenses incurred prior to paying the holders of debt securities of such series.

Before any holder of any series of debt securities may institute action for any remedy, except payment on the holder’s debt security when due, the holders of not less than 25% in principal amount of the debt securities of that series outstanding must request the trustee to take action. Holders must also offer and give the trustee security and indemnity satisfactory to it against liabilities incurred by the trustee for taking such action.

Defeasance

The International Indenture will provide that the Issuer may specify with respect to any series of debt securities that after the Issuer or Omnicom Group Inc. has deposited with the trustee, cash or government securities, in trust for the benefit of the holders sufficient to pay the principal of, premium, if any, and interest on and any mandatory sinking fund payments in respect of the debt securities of such series when due, then the Issuer and Omnicom Group Inc.:

•        will be deemed to have paid and satisfied their obligations on all outstanding debt securities of such series, which is known as “defeasance and discharge”; or

•        will cease to be under any obligation, other than to pay when due the principal of, premium, if any, and interest on and any mandatory sinking fund payments in respect of such debt securities, relating to the debt securities of such series, which is known as “covenant defeasance.”

In each case, the Issuer or Omnicom Group Inc. must also deliver to the trustee an opinion of counsel to the effect that the holders of the debt securities of such series will have no United States federal income tax consequences as a result of such deposit.

In addition, the International Indenture will provide that if we choose to have the defeasance and discharge provision applied to the subordinated debt securities, the subordination provisions of the International Indenture will become ineffective upon full defeasance of the subordinated debt securities.

When there is a defeasance and discharge, with limited exceptions, (1) the International Indenture will no longer govern the debt securities of such series, (2) neither the Issuer nor Omnicom Group Inc. will be liable for payment, and (3) the holders of the debt securities will be entitled only to the deposited funds. When there is a covenant defeasance, however, the Issuer will continue to be obligated to make payments when due if the deposited funds are not sufficient.

Subordination

Debt securities of a series, and any guarantees, may be subordinated, which we refer to as subordinated debt securities, to senior indebtedness (as defined in the applicable prospectus supplement) to the extent set forth in the prospectus supplement relating thereto.

Further Issues

The Issuer may from time to time, without notice to or the consent of the registered holders of a series of debt securities, create and issue further debt securities of any such series ranking equally with the debt securities of the corresponding series in all respects (or in all respects other than the payment of interest accruing prior to the issue date of such further debt securities or except for the first payment of interest following the issue date of such further debt securities). Such further debt securities may be consolidated and form a single series with the debt securities of the corresponding series and have the same terms as to status, redemption or otherwise as the debt securities of the corresponding series.

Concerning the Trustee

The trustee may engage in transactions with, or perform services for, the Issuer, Omnicom Group Inc. and affiliates of the Issuer and Omnicom Group Inc. in the ordinary course of business. The trustee will perform only those duties that are specifically set forth in the International Indenture unless an event of default under the International Indenture occurs and is continuing. In case an event of default occurs and is continuing, the trustee will exercise the same degree of care and skill as a prudent individual would exercise in the conduct of his or her own affairs.

Applicable Law

The debt securities, the guarantee of the debt securities and the International Indenture will be governed by, and construed in accordance with, the laws of the State of New York.
