Item 1.01 Entry into a Material Definitive Agreement.

     See “Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant” below.

Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

     On August 5, 2010, Omnicom Group Inc. (“Omnicom Group”), together with its wholly owned direct finance subsidiaries, Omnicom Capital Inc. and Omnicom Finance Inc. (collectively with Omnicom Group, the “Issuers”), closed their public offering of $1.0 billion aggregate principal amount of 4.450% Senior Notes due 2020 (the “Notes”) pursuant to the Underwriting Agreement, dated August 2, 2010, among the Issuers and J.P. Morgan Securities Inc., as representative of the several underwriters named therein. The Notes have been registered under the Securities Act of 1933 pursuant to the Issuers’ shelf registration statement on Form S-3 (File No. 333-158092) (the “Registration Statement”), which became effective upon filing with the Securities and Exchange Commission (“SEC”) on March 18, 2009.

     The net proceeds received by the Issuers, after deducting the underwriting discount and estimated offering expenses payable by the Issuers, were $988.7 million. The Issuers intend to use such net proceeds 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. The Notes are the joint and several unsecured and unsubordinated obligations of the Issuers and rank equal in right of payment to all of their respective existing and future unsecured senior indebtedness. The Indenture (as defined below) does not contain any provision that would limit the Issuer’s ability to incur 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 Omnicom Group or a takeover, recapitalization or highly leveraged or similar transactions involving Omnicom Group.

     The Notes were issued pursuant to an Indenture, dated as of July 1, 2009 (the “Base Indenture”), between the Issuers and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), as amended by the Second Supplemental Indenture, dated as of August 5, 2010, between the Issuers and the Trustee (the “Supplemental Indenture”). The Notes will bear interest from August 5, 2010, at a rate equal to 4.450% per year, payable semiannually on February 15 and August 15 of each year, commencing on February 15, 2011. Each interest payment will be made to the persons who are registered holders of the Notes on the immediately preceding February 1 and August 1, respectively.

     Subject to certain exceptions, the Base Indenture, together with the Supplemental Indenture (collectively, the “Indenture”), contains covenants limiting the Issuers’ ability and their subsidiaries’ ability to (i) create certain liens; and (ii) consolidate or merge with, or convey, transfer or lease substantially all their assets to, another person.

     The Notes may be declared immediately due and payable by the Trustee or the holders of 25% of the principal amount of the Notes of the affected series if an event of default occurs under the Indenture and has not been cured. An event of default generally means that the Issuers (1) fail to pay the principal on a Note on its due date, (2) fail to pay interest on a Note within 30 days of its due date, (3) remain in breach of any other term of the Indenture for 60 days after their receipt of written notice of such failure, or (4) (A) fail to make any payment by the end of any applicable grace period after maturity of their respective indebtedness, which term as used in the Indenture means obligations (other than non recourse 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. Notwithstanding the foregoing, if the Issuers file for bankruptcy or certain other events in bankruptcy, insolvency or reorganization occurs, the Notes will be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

     The Issuers have the right to redeem some or all of the Notes at any time, or from time to time, at a redemption price equal to the greater of (1) 100% of the principal amount of the Notes and (2) the sum of the present values of the remaining scheduled payments of principal of and interest on the Notes that would be due after the redemption date discounted to the date of redemption, plus a make whole spread equal to 25 basis points, plus accrued and unpaid interest to the redemption date, as applicable.

     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 the Issuers and their affiliates for which they have received, or will receive, customary fees and reimbursement of expenses. J.P. Morgan Securities Inc. and



Citigroup Global Markets Inc. are lead arrangers and book managers of the Omnicom Group credit facility. An affiliate of RBS Securities Inc. is a syndication agent, affiliates of J.P. Morgan Securities Inc., Banc of America Securities LLC, HSBC Securities (USA) Inc. and BBVA Securities Inc. are documentation agents and an affiliate of Citigroup Global Markets Inc. is an administrative agent of the Omnicom Group credit facility. Certain of the other underwriters are also participants in the Omnicom Group credit facility.

     The foregoing description of the issuance, sale and terms of the Notes and of the Base Indenture and Supplemental Indenture does not purport to be complete and is qualified in its entirety by reference to the full text of the Base Indenture and the Supplemental Indenture entered into in connection therewith. The Base Indenture was filed as exhibit 4.1 to Omnicom Group’s Current Report on Form 8-K, filed with the SEC on July 1, 2009, and the Supplemental Indenture is attached hereto as Exhibit 4.1, each of which is incorporated herein by reference.

The Company, in its capacity as guarantor, hereby unconditionally and irrevocably waives (i) any defense arising by reason of any claim or defense based upon an election of remedies by any Holder that in any manner impairs, reduces, releases or otherwise adversely affects the subrogation, reimbursement, exoneration, contribution or indemnification rights of the Company or other rights of the Company to proceed against OCI, OFI, any other guarantor or any other person or collateral, if any, and (ii) any defense based on any right of set-off or counterclaim against or in respect of the Guaranteed Obligations or the Securities of the Company under the Indenture, the Securities or this Supplemental Indenture.

     5.5. The Company, in its capacity as guarantor, hereby waives any right to which it may be entitled to have its obligations under the Guarantee and the Indenture divided among it and other guarantor of the Guaranteed Obligations, if any, such that the Company’s obligations would be less than the full amount claimed. The Company, in its capacity as guarantor, hereby waives any right to which it may be entitled to have the assets of OCI, OFI or any other person who became an “obligor” under the Securities or the Indenture first be used and depleted as payment of the obligations of OCI, OFI or such other person, respectively, under the Securities and the Indenture prior to any amounts being claimed from or paid by the Company under its Guarantee. The Company, in its capacity as guarantor, hereby waives any right to which it may be entitled to require that suit be instituted against OCI, OFI or any other guarantor of the Guaranteed Obligations or “obligor” under the Securities or the Indenture prior to an action being initiated against the Company. The Company further agrees that the Guarantee constitutes a guarantee of payment when due (and not a guarantee of collection) and waives any right, in its capacity as guarantor, to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations.

     5.6. The failure to endorse the Guarantee on any Security shall not affect or impair the validity thereof.

     5.7. The Company’s obligations under its Guarantee shall not be affected if any Holder is precluded for any reason (including, without limitation, the application of the automatic stay under Section 362 of the Bankruptcy Code) from enforcing or exercising any right or remedy with respect to the Securities, and the Company shall pay to each affected Holder, upon demand, the amount that would otherwise have been due and payable had the exercise of such rights and remedies been permitted. In the event of any such application of the automatic stay under Section 362 of the Bankruptcy Code, the Securities shall forthwith become due and payable by the Company for purposes of the Guarantee.

     5.8. The Company hereby agrees that, unless and until all obligations with respect to the Securities and the Indenture, as amended by this Supplemental Indenture, have been paid in full, in its capacity as guarantor, it shall have no right (whether direct or indirect) of subrogation (whether contractual, under Section 509 of the Bankruptcy Code or otherwise) to the claims of any Holder or the Trustee against OCI, OFI or any other person who became an “obligor” under the Securities or the Indenture in respect of any obligation with respect to the Securities or the Indenture, notwithstanding any payment or payments made by the Company hereunder or any

9



set-off or application of funds of the Company by the Holder; and the Company hereby waives all contractual, statutory and common law rights of reimbursement, contribution or indemnity it may have against OCI, OFI or any other such person as the case may be, and any and all other rights of payment or recovery from OCI, OFI or any other such person, as the case may be, that it may now have or hereafter acquire until all Securities and all obligations under the Indenture have been paid in full (in which event such rights of payment or recovery shall be deemed to be in the form of a loan or loans made from the Company to OCI, OFI or any other such person, as the case may be). The Company further agrees that, in its capacity as guarantor, as between the Company, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the Securities guaranteed hereby may be accelerated as provided in Article 6 of the Indenture for the purposes of the Company’s Guarantee hereunder, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Securities guaranteed pursuant to this Section 5, and (2) in the event of any declaration of acceleration of such Securities as provided in Article 6 of the Indenture, such Securities (whether or not due and payable) will forthwith become due and payable by the Company for the purpose of its Guarantee hereunder.

     5.9. Except as otherwise specifically provided in Section 5.12 of this Supplemental Indenture with respect to the release of the Company from its Guarantee hereunder, such Guarantee shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon the Company and the successors thereof, and shall inure to the benefit of (and be enforceable by) the Trustee and the Holders from time to time, or their respective successors or assignees, until the Indenture shall have been terminated and the principal of and interest, if any, on the Securities, and the obligations of the Company in respect of the Guaranteed Obligations, have been satisfied by payment in full.

     5.10. Payments made by the Company pursuant to its Guarantee hereunder will be made to each Holder in the same manner, and to the same location, as payments to such Holder are required to be made pursuant to the provisions of the Indenture.

     5.11. The Company shall pay all reasonable costs and expenses (including reasonable attorneys’ fees and expenses) paid or incurred by the Trustee or any Holder in connection with the enforcement of the Guarantee or any other rights of the Trustee or such Holder under this Supplemental Indenture with respect to such Guarantee and the prosecution or defense of any action by or against any of the Holders in connection with the Guarantee or this Supplemental Indenture with respect to such Guarantee, whether involving the Company or any other person, including a trustee in bankruptcy; provided, however, that the Company shall have no such obligation in connection with any action brought by any Holder against the Company to the extent that the Company is the prevailing party in the judgment rendered in any such action; and provided further that the Company shall not be responsible for the fees and expenses of more than one firm of attorneys (in addition to any required local counsel).

     5.12. The Company may, by execution and delivery to the Trustee of a supplemental indenture satisfactory to the Trustee, be released from its Guarantee upon the sale or other transfer of its capital stock or of all or substantially all of its assets to an entity that is not the Company or a subsidiary of the Company and which sale is otherwise in compliance with the Indenture, which release shall be effective without any action on the part of the Trustee or any Holder. Upon any such release, the Trustee shall deliver an appropriate instrument evidencing

10



such release upon receipt of a request by the Company or the Company accompanied by an Officers’ Certificate certifying as to compliance with this Section 5.12. Any actions taken pursuant to this Section 5.12 shall not release the Company, OCI or OFI as a primary obligor under the Indenture or the Securities.

4.450% Senior Notes due 2020

     This Security is one of a duly authorized issue of securities of the Issuers, designated as their 4.450% Senior Notes due 2020 (herein called the “Securities”), issued and to be issued in one or more Series under an Indenture, dated as of July 1, 2009 (herein called the “Base Indenture”), between the Issuers and Deutsche Bank Trust Company Americas, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), as amended and supplemented by the Second Supplemental Indenture, dated as of August 5, 2010 between the Issuers and the Trustee (the “Supplemental Indenture” and together with the Base Indenture, the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Issuers, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $1,000,000,000. Capitalized terms used in this Security and not defined herein have the meaning ascribed thereto in the Indenture.

     Deutsche Bank Trust Company Americas, the Trustee under the Indenture has been appointed by the Issuers as paying agent, registrar and custodian with regard to the Securities.

     In case an Event of Default shall have occurred and be continuing, the principal of and accrued interest on all Securities may be declared, and upon said declaration, shall become due and payable, in the manner, with the effect and subject to the conditions provided for in the Indenture.

     The 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 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 Securities to be redeemed and (2) the sum of the present values of the Remaining Scheduled Payments on the 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 plus 25 basis points, 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 having a maturity comparable to the remaining term of the 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 Securities.

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



     “ Reference Treasury Dealer ” means any three primary U.S. Government securities dealer selected by the Issuers 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 Trustee 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 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 Securities, the amount of the next succeeding scheduled interest payment on the Securities will be reduced by the amount of interest accrued on the 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, 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 Securities or any portion of the Securities called for redemption (unless the Issuers default in the payment of the redemption price and accrued interest). On or before the redemption date, the Issuers will deposit with a paying agent (or the Trustee) money sufficient to pay the redemption price of and accrued interest on the Securities to be redeemed on that date. If less than all of the Securities are to be redeemed, the Securities to be redeemed shall be selected by the Trustee by a method the Trustee deems to be fair and appropriate.

     In the event of redemption of this Security in part only, a new Security or Securities of this Series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

     The Indenture contains provisions that permit the Issuers to elect either (1) to defease and be discharged from the entire indebtedness of this Security or (2) to be released from their obligations under certain restrictive covenants and Events of Default with respect to this Security, in each case upon payment in full of the Securities and compliance with certain conditions set forth in the Indenture.

     If an Event of Default with respect to Securities of this Series shall occur and be continuing, the principal of the Securities of this Series may be declared due and payable in the manner and with the effect provided in the Indenture.

     The Indenture permits the amendment thereof and the modification of the rights and obligations of the Issuers and the rights of the Holders of the Securities of each Series to be affected under the Indenture at any time by the Issuers and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time outstanding of each Series to be affected, with certain exceptions as therein provided with respect to certain modifications



or amendments which may not be made without the consent of each Holder of such Security affected thereby. The Indenture also permits certain amendments and modifications thereto from time to time by the Issuers and the Trustee without the consent of the Holders of any Series of the Securities to be affected thereby for certain specified purposes, including curing ambiguities, defects or inconsistencies and making any such change that does not adversely affect the rights of any Holder of such series of the Securities, as provided therein.

     The Indenture contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each Series at the time outstanding, on behalf of the Holders of all Securities of such Series, to waive compliance by the Issuers with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

     No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Issuers, which is absolute and unconditional, to pay the principal of and any premium and Interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the security register, upon surrender of this Security for registration of transfer at the office or agency of the Issuers in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuers and the security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this Series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

     The Securities of this Series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this Series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or exchange, but the Issuers may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Security for registration of transfer, the Issuers, the Trustee and any agent of the Issuers or the Trustee may treat the person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security is overdue, and neither the Issuers, the Trustee nor any such agent shall be affected by notice to the contrary.



     No recourse shall be had for the payment of the principal of (and premium, if any) or interest on this Security, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Issuers or of any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

     All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture
