ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the SEC utilizing a “shelf” registration process. Under this shelf process, we may sell any combination of the securities described in this prospectus in one or more offerings. This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a prospectus supplement and, if applicable, a free writing prospectus that will contain specific information about the terms of that offering. The prospectus supplement will describe: the terms of the securities offered, any initial public offering price, the price paid to us for the securities, the net proceeds to us, the manner of distribution and any underwriting compensation and the other specific material terms related to the offering of the applicable securities. For more detail on the terms of the securities, you should read the exhibits filed with or incorporated by reference in our registration statement of which this prospectus forms a part. The prospectus supplement and any related free writing prospectus may also add, update or change information contained in this prospectus. If there is any inconsistency between the information in this prospectus and in any prospectus supplement or free writing prospectus, you should rely on the information in that prospectus supplement or free writing prospectus, as applicable. You should read this prospectus, any prospectus supplement and any free writing prospectus together with additional information described under the heading “Where You Can Find More Information; Incorporation by Reference.”

Pursuant to this registration statement Omnicom Group Inc. may offer, issue and sell securities as set forth on the cover page of this prospectus. Because Omnicom Group Inc. is a “well-known seasoned issuer,” as defined in Rule 405 of the Securities Act of 1933, as amended, which we refer to in this prospectus as the “Securities Act,” Omnicom Group Inc. may add to and offer additional securities, including securities held by security holders, by filing a prospectus supplement with the SEC at the time of the offer. In addition, Omnicom Group Inc. is able to add its subsidiaries and securities to be issued by them if Omnicom Group Inc. guarantees such securities. Omnicom Group Inc. will guarantee any debt securities that Omnicom Capital issues under this prospectus.

SPECIAL NOTE ON FORWARD-LOOKING STATEMENTS

Certain statements in this prospectus constitute forward-looking statements, including statements within the meaning of the Private Securities Litigation Reform Act of 1995. In addition, from time to time, we or our representatives have made, or may make, forward-looking statements, orally or in writing. These statements may discuss goals, intentions and expectations as to future plans, trends, events, results of operations or financial condition, or otherwise, based on current beliefs of our management as well as assumptions made by, and information currently available to, our management. Forward-looking statements may be accompanied by words such as “aim,” “anticipate,” “believe,” “plan,” “could,” “should,” “would,” “estimate,” “expect,” “forecast,” “future,” “guidance,” “intend,” “may,” “will,” “possible,” “potential,” “predict,” “project” or similar words, phrases or expressions. These forward-looking statements are subject to various risks and uncertainties, many of which are outside our control. Therefore, you should not place undue reliance on such statements. Factors that could cause actual results to differ materially from those in the forward-looking statements include: international, national or local economic, social or political conditions that could adversely affect us or our clients; losses on media purchases and production costs incurred on behalf of clients; reductions in client spending, a slowdown in client payments and changes in client advertising, marketing and corporate communications requirements; failure to manage potential conflicts of interest between or among clients; unanticipated changes relating to competitive factors in the advertising, marketing and corporate communications industries; ability to hire and retain key personnel; ability to attract new clients and retain existing clients in the manner anticipated; reliance on information technology systems; changes in legislation or governmental regulations affecting us or our clients; conditions in the credit markets; risks associated with assumptions we make in connection with our critical accounting estimates and legal proceedings; and our international operations, which are subject to the risks of currency fluctuation and currency repatriation restrictions. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties that may affect our business, including those described in “Risk

3 

Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2014. Except as required under applicable law, we do not assume any obligation to update these forward-looking statements.

USE OF PROCEEDS

Unless otherwise specified in an applicable prospectus supplement, Omnicom Group will use the proceeds it receives from the sale of the offered securities for general corporate purposes, which could include working capital expenditures, fixed asset expenditures, acquisitions, refinancing of other debt, repurchases of Omnicom Group’s common stock or other capital transactions. Pending the application of the proceeds, we may invest proceeds in short-term investment grade obligations. The precise amounts and timing of the application of proceeds will depend upon the funding requirements of Omnicom Group Inc. and its subsidiaries at the time of issuance and the availability of other funds.

RATIO OF EARNINGS TO FIXED CHARGES

The following table shows the ratio of earnings to fixed charges of Omnicom Group Inc. for each of the periods indicated.

Nine Months Ended	Year Ended December 31,
September 30, 2015	2014	2013	2012	2011	2010
6.57x	6.93x	6.07x	6.26x	6.32x	6.12x

The ratio of earnings to fixed charges is computed by dividing fixed charges into income before income taxes plus dividends from equity method investments and fixed charges. Fixed charges consist of interest expense and that portion of net rental expense deemed representative of interest.

Since we had no preferred stock outstanding during any of the periods presented, the ratios of earnings to fixed charges and the ratios of earnings to combined fixed charges and preferred dividends are the same.

DESCRIPTION OF OMNICOM GROUP INC. COMMON STOCK

General

The following briefly summarizes the material terms of Omnicom Group Inc.’s common stock. You should read the more detailed provisions of Omnicom Group Inc.’s restated certificate of incorporation for provisions that may be important to you.

Omnicom Group Inc.’s restated certificate of incorporation authorizes it to issue up to 1,000,000,000 shares of common stock, par value $.15 per share. As of October 15, 2015, Omnicom Group Inc. had 242,255,205 shares of its common stock outstanding.

Each holder of common stock is entitled to one vote per share for the election of directors and for all other matters to be voted on by Omnicom Group Inc. shareholders. Holders of common stock may not cumulate their votes in the election of directors, and are entitled to share equally in the dividends that may be declared by the board of directors, but only after payment of dividends required to be paid on any outstanding shares of preferred stock.

Omnicom Group Inc.’s shareholders elect the full board of directors annually. An affirmative vote of the holders of a majority of votes cast is required for Omnicom Group Inc.’s shareholders to remove a director, amend Omnicom Group Inc.’s by-laws or its restated certificate of incorporation and to change the number of directors comprising the full board.

The board of directors also has power to amend the by-laws or change the number of directors comprising the full board.

Upon voluntary or involuntary liquidation, dissolution or winding up of Omnicom Group Inc., the holders of the common stock share ratably in the assets remaining after payments to creditors and provision for the preference of any preferred stock. There are currently no preemptive or other subscription rights, conversion rights or redemption or scheduled installment payment provisions relating to shares of common stock. All of the outstanding shares of common stock are fully paid and nonassessable.

DESCRIPTION OF OMNICOM GROUP INC. PREFERRED STOCK

The following briefly summarizes the material terms of Omnicom Group Inc.’s preferred stock, other than pricing and related terms to be disclosed in a prospectus supplement. You should read the particular terms of any series of preferred stock offered by Omnicom Group Inc. which will be described in more detail in any prospectus supplement relating to such series, together with the more detailed provisions of Omnicom Group Inc.’s restated certificate of incorporation and the certificate of designation relating to each particular series of preferred stock, for provisions that may be important to you. The restated certificate of incorporation is incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part. The certificate of designation relating to the particular series of preferred stock offered by a prospectus supplement relating to the series’ issue will be filed as an exhibit to one of Omnicom Group Inc.’s future current reports and incorporated by reference in the registration statement to which this prospectus relates. The prospectus supplement will also state whether any of the terms summarized below do not apply to the series of preferred stock being offered.

General

As of the date of this prospectus, Omnicom Group Inc. is authorized to issue up to 7.5 million shares of preferred stock, par value $1.00 per share, none of which is outstanding.

Under Omnicom Group Inc.’s restated certificate of incorporation, the board of directors of Omnicom Group Inc. is authorized to issue, without the approval of Omnicom Group Inc.’s shareholders, shares of preferred stock in one or more series, and to establish from time to time a series of preferred stock having such powers, preferences, rights and limitations as the board of directors so designates.

Prior to the issuance of any series of preferred stock, the board of directors of Omnicom Group Inc. will adopt resolutions creating and designating the series as a series of preferred stock and the resolutions will be filed with the New York State Secretary of State as an amendment to the restated certificate of incorporation.

The resolutions of the board of directors of Omnicom Group Inc. providing for a series of preferred stock may include the following provisions:

• the title and stated value of the preferred stock;

• the number of shares of the preferred stock offered, the liquidation preference per share and the purchase price of the preferred stock;

• the dividend rate, period and/or payment date or method of calculation thereof applicable to the preferred stock;

• whether dividends shall be cumulative or non-cumulative and, if cumulative, the date from which dividends on the preferred stock shall accumulate;

• the provisions for a sinking fund, if any, for the preferred stock;

• the provisions for redemption, if applicable, of the preferred stock;

• the terms and conditions, if applicable, upon which the preferred stock will be convertible into or exchangeable for other types of securities, including the conversion price (or a manner of calculation thereof) and conversion period;

• voting rights, if any, of the preferred stock;

• whether interests in the preferred stock will be represented by depositary shares; and

• any other specific terms, preferences, rights, limitations or restrictions of the preferred stock.

5 

The rights of holders of the preferred stock offered may be affected by the rights of holders of any shares of preferred stock that may be issued in the future. Those effects could be adverse. Shares of preferred stock issued by Omnicom Group Inc. may have the effect of rendering more difficult or discouraging an acquisition of Omnicom Group Inc. deemed undesirable by the board of directors of Omnicom Group Inc.

The preferred stock will be, when issued, fully paid and nonassessable. Holders of preferred stock will not have any preemptive or subscription rights to acquire more stock of Omnicom Group Inc.

The transfer agent, registrar, dividend disbursing agent and redemption agent for shares of each series of preferred stock will be named in the prospectus supplement relating to such series.

Rank

Unless otherwise specified in the prospectus supplement relating to the shares of any series of preferred stock, the shares will rank on an equal basis with each other series of preferred stock and prior to the common stock as to dividends and distributions of assets.

Dividends

Holders of each series of preferred stock will be entitled to receive cash dividends when, as and if declared by the board of directors of Omnicom Group Inc. out of funds legally available for dividends. The rates and dates of payment of dividends will be set forth in the prospectus supplement relating to each series of preferred stock. Dividends will be payable to holders of record of preferred stock as they appear on the books of Omnicom Group Inc. on the record dates fixed by the board of directors. Dividends on any series of preferred stock may be cumulative or noncumulative.

Conversion and Exchange

The prospectus supplement for any series of preferred stock will state the terms, if any, on which shares of that series are convertible into or exchangeable for other types of securities of Omnicom Group Inc.

Redemption

If so specified in the applicable prospectus supplement, a series of preferred stock may be redeemable at any time, in whole or in part, at the option of Omnicom Group Inc. or the holder thereof and may be mandatorily redeemed.

Any partial redemptions of preferred stock will be made in a way that the board of directors decides is equitable.

Unless Omnicom Group Inc. defaults in the payment of the redemption price, dividends will cease to accrue after the redemption date on shares of preferred stock called for redemption and all rights of holders of such shares will terminate except for the right to receive the redemption price.

Liquidation Preference

Upon any voluntary or involuntary liquidation, dissolution or winding up of Omnicom Group Inc., holders of each series of preferred stock will be entitled to receive distributions upon liquidation in the amount set forth in the prospectus supplement relating to such series of preferred stock, plus an amount equal to any accrued and unpaid dividends. Those distributions will be made before any distribution is made on any securities ranking junior relating to liquidation, including common stock.

If the liquidation amounts payable relating to the preferred stock of any series and any other securities ranking on a parity regarding liquidation rights are not paid in full, the holders of the preferred stock of such series and such other securities will share in any such distribution of available assets of Omnicom Group Inc. on a ratable basis in proportion to the full liquidation preferences.

Holders of preferred stock will not be entitled to any other amounts from Omnicom Group Inc. after they have received their full liquidation preference.

6 

Voting Rights

The holders of shares of preferred stock will have no voting rights, except:

• as otherwise stated in the prospectus supplement;

• as otherwise stated in the certificate of designation establishing such series; or as required by applicable law.

DESCRIPTION OF DEBT SECURITIES

General

The description below of the general terms of the debt securities will be supplemented by the more specific terms of a particular series in a prospectus supplement.

The debt securities offered by this prospectus will be joint and several unsecured obligations of Omnicom Group Inc. and Omnicom Capital and will be either senior or subordinated debt. We will issue the debt securities under an indenture between us and Deutsche Bank Trust Company Americas, or the Trustee. The 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 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 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 indenture.

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

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

• may rank equally with other unsubordinated debt or may be subordinated to other debt the Issuers 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 depositary’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 depositary and its participants.

Omnicom Group Inc. is a holding company and Omnicom Capital is a finance subsidiary. As a finance subsidiary, Omnicom Capital’s assets consist of the intercompany loans it makes or has made to Omnicom Group Inc.’s operating subsidiaries and the related interest receivables. As a result, the debt securities issued under the indenture will effectively be subordinated to all existing and future obligations of Omnicom Group Inc.’s operating subsidiaries, including trade payables, and to the Issuers’ respective obligations that are secured, to the extent of the security. Omnicom Capital’s obligations in respect of any debt securities will be guaranteed by Omnicom Group Inc.

The aggregate principal amount of debt securities that the Issuers 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;

7 

• 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 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 Issuers. 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

8 

issued only in denominations of $1,000 and whole multiples of $1,000. 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 Issuers 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 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 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 indenture.

The Issuers 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 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 Issuers’ option, at any time or from time to time, upon mailed notice to the registered address of each holder of debt securities at least 30 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.

“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.

“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.

9 

“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 Issuers, 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 Issuers 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 would be due after the related redemption date but for that redemption. 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.

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).

Consolidation, Merger or Sale

The Issuers 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 Omnicom Capital with, into or to Omnicom Group Inc., or any other subsidiary of Omnicom Group Inc., unless:

• either (a) an Issuer is the continuing person or (b) the resulting, surviving or transferee person is an entity organized under the laws of the United States;

• the successor person expressly assumes the respective Issuer’s obligations with respect to the debt securities and the 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 respective Issuer or the successor person has delivered to the trustee the certificates and opinions required under the indenture.

Modification of the Indenture

Under the indenture, the Issuers 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 indenture’s provisions regarding successor corporations;

• to comply with any requirements of the SEC in connection with the qualification of the 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 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 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 indenture.

10 

The Issuers 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 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 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 indenture provides 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 applicable indenture (other than a covenant included in the applicable indenture solely for the benefit of a series of debt securities other than such series);

• (A) the Issuers’ failure to make any payment by the end of any applicable grace period after maturity of their respective indebtedness, which term as used in the applicable indenture means obligations (other than nonrecourse obligations) of the Issuers 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 Issuers by the trustee or to the Issuers 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.

11 

If an event of default (other than the bankruptcy provision) regarding debt securities of any series issued under the 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 Issuers are required to file annually with the trustee a statement of an officer as to the fulfillment by the Issuers of their respective obligations under the applicable 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 applicable 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 applicable 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 indenture provides that the Issuers may specify with respect to any series of debt securities that after the Issuers have 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 Issuers:

• 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 Issuers 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 indenture provides that if we choose to have the defeasance and discharge provision applied to the subordinated debt securities, the subordination provisions of the indenture will become ineffective upon full defeasance of the subordinated debt securities.

When there is a defeasance and discharge, (1) the indenture will no longer govern the debt securities of such series, (2) the Issuers 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 Issuers 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

12 

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 Issuers 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 Issuers and affiliates of the Issuers in the ordinary course of business. The trustee will perform only those duties that are specifically set forth in the indenture unless an event of default under the 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 and the indenture will be governed by, and construed in accordance, with the laws of the State of New York.

Item 15. Indemnification of Directors and Officers.

Omnicom Group Inc.

Omnicom Group Inc.’s restated certificate of incorporation contains a provision limiting the liability of directors (except for approving statutorily prohibited dividends, share repurchases or redemptions, distributions of assets on dissolution or loans to directors) to acts or omissions determined by a judgment or other final adjudication to have been in bad faith, involving intentional misconduct or a knowing violation of the law, or resulting in personal gain to which the director was not legally entitled. Omnicom Group Inc.’s by-laws provide that an officer or director will be indemnified against any costs or liabilities, including attorney’s fees and amounts paid in settlement with Omnicom Group Inc.’s consent in connection with any claim, action or proceeding to the fullest extent permitted by the New York Business Corporation Law, or the NYBCL.

Omnicom Group Inc. has entered into indemnification agreements with each of its executive officers, directors and certain other employees. Under the indemnification agreements, Omnicom Group Inc. agrees to indemnify the indemnitee to the fullest extent permitted by applicable law if the indemnitee is made, or is threatened to be made, a party to any proceeding (including a proceeding by or in the right of Omnicom Group Inc. to procure a judgment in its favor) against all expenses, judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such expenses, judgments, fines, penalties and amounts paid in settlement) actually and necessarily incurred by indemnitee in connection with the proceeding. In addition, to the extent that the indemnitee is, by reason of his corporate status, a witness in any proceeding to which the indemnitee is not a party, Omnicom Group Inc. agrees to indemnify and hold harmless the indemnitee against all expenses actually and necessarily incurred by him or on his behalf in connection therewith. Omnicom Group Inc. also agrees, to the extent the Company maintains liability insurance applicable to agents of Omnicom Group Inc. or of any other enterprise which such agent serves at the request of Omnicom Group Inc., the indemnitee will be covered by such policies in accordance with its or their terms to the maximum extent of the coverage available for any such agent under such policy or policies.

Section 721 of the NYBCL provides that, in addition to indemnification provided in Article 7 of the NYBCL, a corporation may indemnify a director or officer by a provision contained in the certificate of incorporation or by-laws or by a duly authorized resolution of its shareowners or directors or by agreement, provided that no indemnification may be made to or on behalf of any director or officer if a judgment or other final

II-1

adjudication adverse to the director or officer establishes that his acts were committed in bad faith or were the result of active and deliberate dishonesty and material to the cause of action, or that such director or officer personally gained in fact a financial profit or other advantage to which he was not legally entitled.

Section 722(a) of the NYBCL provides that a corporation may indemnify a director or officer made, or threatened to be made, a party to any action other than a derivative action, whether civil or criminal, against judgments, fines, amounts paid in settlement and reasonable expenses, including attorneys’ fees, actually and necessarily incurred as a result of such action or proceeding or any appeal therein, if such director or officer acted in good faith, for a purpose which he reasonably believed to be in, or not opposed to, the best interests of the corporation and, in criminal actions or proceedings, in addition, had no reasonable cause to believe that his conduct was unlawful.

Section 722(c) of the NYBCL provides that a corporation may indemnify a director or officer, made or threatened to be made a party in a derivative action, against amounts paid in settlement and reasonable expenses, including attorneys’ fees, actually and necessarily incurred by him in connection with the defense or settlement of such action or in connection with an appeal therein if such director or officer acted in good faith, for a purpose which he reasonably believed to be in, or not opposed to, the best interests of the corporation, except that no indemnification will be available under Section 722(c) of the NYBCL in respect of a threatened or pending action which is settled or otherwise disposed of, or any claim as to which such director or officer shall have been adjudged liable to the corporation, unless and only to the extent that the court in which the action was brought, or, if no action was brought, any court of competent jurisdiction, determines, upon application, that, in view of all the circumstances of the case, the director or officer is fairly and reasonably entitled to indemnity for such portion of the settlement amount and expenses as the court deems proper.

Section 723 of the NYBCL specifies the manner in which payment of indemnification under Section 722 of the NYBCL or indemnification permitted under Section 721 of the NYBCL may be authorized by the corporation. It provides that indemnification may be authorized by the corporation. It provides that indemnification by a corporation is mandatory in any case in which the director or officer has been successful, whether on the merits or otherwise, in defending an action. In the event that the director or officer has not been successful or the action is settled, indemnification must be authorized by the appropriate corporate action as set forth in Section 723.

Section 724 of the NYBCL provides that, upon application by a director or officer, indemnification may be awarded by a court to the extent authorized. Section 722 and Section 723 of the NYBCL contain certain other miscellaneous provisions affecting the indemnification of directors and officers.

Section 726 of the NYBCL authorizes the purchase and maintenance of insurance to indemnify (1) a corporation for any obligation which it incurs as a result of the indemnification of directors and officers under the provisions of Article 7 of the NYBCL, (2) directors and officers in instances in which they may be indemnified by the corporation under the provisions of Article 7 of the NYBCL, and (3) directors and officers in instances in which they may not otherwise be indemnified by the corporation under the provisions of Article 7 of the NYBCL, provided the contract of insurance covering such directors and officers provides, in a manner acceptable to the New York State Superintendent of Insurance, for a retention amount and for co-insurance.

Omnicom Group Inc. has purchased liability insurance for its officers and directors as permitted by Section 726 of the NYBCL.

Sections 33-770 through 33-776 of the Business Corporation Act of the State of Connecticut provide that a corporation may indemnify a director or officer against judgments, fines, penalties, amounts paid in settlement and reasonable expenses actually incurred by him or her, including attorneys’ fees, for actions brought or threatened to be brought against him or her in his or her capacity as a director or officer, other than actions brought by or in the right of the corporation, when it is determined by certain disinterested parties that he or she acted in good faith in a manner he or she reasonably believed to be in the corporation’s best interest (or in the case of conduct not in his or her official capacity, at least not opposed to the best interests of the corporation). In any criminal action or proceeding, it also must be determined that the director or officer had no reasonable cause to believe that his or her

II-2

conduct was unlawful. A director or officer must be indemnified when he or she is wholly successful on the merits or otherwise in the defense of a proceeding or in circumstances where a court determines that he or she is fairly and reasonably entitled to be indemnified. In connection with shareholder derivative suits, a director or officer may not be indemnified unless he or she is finally adjudged (a) to have met the relevant standard of conduct described above and (b) not to have received a financial benefit to which he or she was not entitled, whether or not he or she was acting in his or her official capacity. Omnicom Capital maintains and pays premiums for its directors’ and officers’ liability insurance policies.

Item 16. Exhibits.

The exhibits to this registration statement are listed in the exhibit index, which appears elsewhere herein and is incorporated herein by reference.

Item 17. Undertakings.

(a)The undersigned registrant hereby undertakes:

(1)To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii)To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent posteffective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(iii)To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that Paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of this registration statement.

(2)That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

II-3

(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5)That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b)The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)The undersigned registrant hereby undertakes to supplement the prospectus, after the expiration of the subscription period, to set forth the results of the subscription offer, the transactions by the underwriters during the subscription period, the amount of unsubscribed securities to be purchased by the underwriters, and the terms of any subsequent reoffering thereof. If any public offering by the underwriters is to be made on terms differing from

II-4

those set forth on the cover page of the prospectus, a post-effective amendment will be filed to set forth the terms of such offering.

(d)Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
