SUBJECT TO COMPLETION DATED APRIL 12, 2002 PROSPECTUS $900,000,000 OMNICOM GROUP INC. Zero Coupon Zero Yield Convertible Notes due 2032 ---------- The Offering: We sold the notes in private transactions on March 6, 2002 and March 19, 2002. Selling securityholders may use this prospectus to resell their notes and the shares of common stock issuable upon conversion and/or redemption of their notes.The notes are zero-coupon debt securities. On July 31, 2032, the maturity date of the notes, a holder will receive the principal amount at maturity of the notes, which will be $1,000 per note unless that amount is increased on and after July 31, 2022 as described in this prospectus. The notes are senior unsecured obligations and rank equal in right of payment to all of our existing and future senior unsecured indebtedness. Convertibility of the Notes: Holders may convert each $1,000 initial principal amount at maturity of their notes into 9.09 shares of our common stock, subject to adjustment, as described in this prospectus. When a holder surrenders notes for conversion, the conversion agent may first offer the notes to a financial institution chosen by us who will have the option, but not the obligation (unless separately agreed to by it and us at the time), to agree to exchange those notes for the number of shares of our common stock that the holder of those notes would have otherwise been entitled to receive upon conversion, plus cash for any fractional shares. Our common stock currently trades on the New York Stock Exchange under the symbol "OMC." The last reported sale price of our common stock on the New York Stock Exchange was $93.31 per share on April 11, 2002. Contingent Cash Interest: We will pay contingent cash interest to the holders of notes during the six-month period commencing August 1, 2007 and during any six-month period thereafter until maturity if the average market price of a note for a five trading day measurement period preceding the applicable six-month period equals 120% or more of the initial principal amount at maturity of the note. For any six-month period, the amount of contingent cash interest payable per note will be equal to the amount of regular cash dividends paid by us per share on our common stock during that six-month period multiplied by the number of shares issuable upon conversion of a note at the then applicable conversion rate. For United States federal income tax purposes, the notes constitute contingent payment debt instruments. You should read the discussion of selected United States federal income tax consequences relevant to the notes beginning on page 27. Purchase of the Notes by Omnicom at the Option of the Holder: Holders may require us to purchase all or a portion of their notes on each July 31 (or if July 31 is not a business day, the next succeeding business day), commencing July 31, 2003, with payment on the fourth business day following such purchase date, at the prices set forth in this prospectus. We may choose to pay the purchase price in cash, shares of common stock or a combination of cash and common stock. When a holder surrenders the notes for purchase, the purchase agent may first offer the notes to a financial institution chosen by us to purchase the notes who will have the option, but not the obligation (unless separately agreed to by it and us at the time), to purchase the notes at the applicable purchase price. In addition, upon a change in control of Omnicom occurring on or before July 31, 2007, holders may require us to purchase all or a portion of their notes for cash at a purchase price of $1,000 per note. If 90% or more of the outstanding notes are purchased in any such event, we may redeem all of the remaining notes for cash at a redemption price of $1,000 per note. Redemption of the Notes at the Option of Omnicom: We may redeem all or a portion of the notes for cash at any time on or after July 31, 2007 at the initial principal amount at maturity or, if the principal amount at maturity has been increased, at the initial principal amount at maturity plus accrued contingent additional principal. ---------- Investing in the Notes involves risks that are described in the "Risk Factors Relating to the Notes" section beginning on page 10 of this prospectus. ---------- The notes issued in the initial private placements are eligible for trading in the PORTAL System. The notes sold using this prospectus, however will no longer be eligible for trading in the PORTAL System. We do not intend to list the notes on any other national securities exchange or automated quotation system. Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete.

You should read the entire prospectus, as well as the information incorporated by reference, before making an investment decision.

Maturity of the Notes ............ July 31, 2032. Principal Amount at Maturity of the Notes ............ Before July 31, 2022, the principal amount at maturity of a note will be equal to $1,000 per $1,000 principal amount of notes, which we refer to as the initial principal amount at maturity. On or after July 31, 2022, if, for the last 20 trading days preceding July 31, 2022, the average conversion value of a note is greater than the initial principal amount at maturity but less than or equal to 220% of the initial principal amount at maturity, then the principal amount at maturity of a note will be equal to the conversion value of the note on July 31, 2022, but in no event greater than 200% of the initial principal amount at maturity. If that conversion value exceeds 220% of the initial principal amount at maturity, then the principal amount at maturity will equal the initial principal amount at maturity. The conversion value of a note as of any date of determination will equal the sale price per share of our common stock on that determination date multiplied by the number of shares of common stock then issuable upon conversion of a note. If the principal amount at maturity is increased, then contingent additional principal, the difference between the initial principal amount at maturity and the principal amount at maturity, will accrue from and including July 31, 2022 until maturity. No Cash Interest ................. We will not pay any cash interest on the notes prior to maturity, unless contingent cash interest becomes payable or we elect to do so in our sole discretion. Yield to Maturity of the Notes ... The yield to maturity (except contingent cash interest payments, if any), calculated on the basis of the initial principal amount at maturity, will be zero unless, for the last 20 trading days preceding July 31, 2022, the average conversion value of a note is greater than the initial principal amount at maturity but less than 220% of the initial principal amount at maturity, in which case contingent additional principal will accrue daily from July 31, 2022 on the issue price of the note ratably to the principal amount at maturity of the note, which represents the initial principal amount at maturity plus contingent additional principal. The yield to maturity will be negative to the extent that the price paid by a purchaser of the notes is in excess of the initial principal amount at maturity of the notes. -------------------------------------------------------------------------------- 5 -------------------------------------------------------------------------------- Contingent Cash Interest ......... We will pay contingent cash interest to the holders of notes during any six-month period from August 1 to January 31, and from February 1 to July 31, commencing August 1, 2007, if the average market price of a note for a five trading day measurement period preceding the applicable six-month period equals 120% or more of the initial principal amount at maturity of the note. For any six-month period, the amount of contingent cash interest payable per note will be equal to the regular cash dividends paid by us per share on our common stock in that period multiplied by the number of shares issuable upon conversion of a note. Contingent cash interest, if any, will accrue and be payable to holders of notes as of the record date for the related common stock dividend during the relevant six-month period. The payments will be made on the payment date for the related common stock dividend. If we do not pay regular cash dividends, holders will not be entitled to any contingent cash interest. Tax Original Issue Discount ...... The notes are debt instruments subject to the United States federal income tax contingent payment debt regulations. The notes are deemed to have been issued with original issue discount for United States federal income tax purposes, referred to as tax original issue discount. You should be aware that, even though we will not pay any interest (except for contingent cash interest, if any) on the notes and the notes will not be nominally issued at a discount, you will be required to include accrued tax original issue discount in your gross income for United States federal income tax purposes. We intend to compute and report accruals of the tax original issue discount based upon a yield of 6.69% per year, computed on a semiannual bond equivalent basis, which we have determined represents the yield we would pay on noncontingent, nonconvertible, fixed-rate debt with terms otherwise similar to the notes. In accordance with our application of the contingent payment debt tax regulations, you will also recognize gain or loss on the sale, exchange, conversion or redemption of a note in an amount equal to the difference between the amount realized, including the fair market value of any common stock received, and your adjusted tax basis in the note. Any gain recognized by you generally will be ordinary interest income; any loss will be ordinary loss to the extent of the interest previously included in income and, thereafter, capital loss. However, it is possible that deductions for capital losses realized upon conversion or redemption for stock may not be allowed under certain rules regarding recapitalizations. Conversion Rights ................ For each $1,000 initial principal amount at maturity of a note surrendered for conversion, if the conditions for -------------------------------------------------------------------------------- 6 -------------------------------------------------------------------------------- conversion are satisfied, a holder will receive 9.09 shares of our common stock. The conversion rate will be adjusted for reasons specified in the indenture but will not be adjusted for accrued contingent additional principal, if any or contingent cash interest, if any. Before July 31, 2022, holders may surrender a note for conversion during any calendar quarter commencing after March 31, 2002 if, for the last 20 trading days in the preceding calendar quarter, the average conversion value of the note is greater than or equal to a specified percentage, initially 125% and increasing 5% per quarter up to a maximum of 220%, of the initial principal amount at maturity of the note. On or after July 31, 2022, holders may surrender a note for conversion during any calendar quarter if, for the last 20 trading days in the preceding calendar quarter, the average conversion value of the note is greater than or equal to 110% of the principal amount at maturity of the note. If either of the foregoing conditions is satisfied, then the notes will thereafter be convertible at any time at the option of the holder, through maturity. Holders may also surrender a note for conversion at the then-applicable conversion rate at any time after the credit rating assigned to the notes is reduced to Baa3 or lower by Moody's Investors Service, Inc. or BBB or lower by Standard & Poor's Ratings Services. In addition, if we call the notes for redemption or if we make any significant distribution to our stockholders, or enter into any merger or binding share exchange, the notes may be surrendered for conversion even if the foregoing conditions are not satisfied. The ability to surrender notes for conversion will expire at the close of business on July 31, 2032. When a holder surrenders notes for conversion, the conversion agent may first offer the notes to a financial institution chosen by us for exchange in lieu of conversion. The designated institution will have the option, but not the obligation (unless separately agreed to by it and us at the time) to agree to exchange those notes for the number of shares of our common stock that the holder of those notes would have been entitled to receive upon conversion, plus cash for any fractional shares. We may, but will not be obligated to enter into a separate agreement with the financial institution which would compensate it for any such transaction. Ranking .......................... The notes are senior unsecured obligations of Omnicom and will rank equal in right of payment to all our existing and future senior unsecured indebtedness. The notes are effectively subordinated to all of our existing and future obligations of our subsidiaries and to our obligations that are secured, to the extent of the security. -------------------------------------------------------------------------------- 7 -------------------------------------------------------------------------------- As of December 31, 2001, we had $1,424.3 million of indebtedness outstanding, all of which is unsecured, $985.6 million of which is issued by us and $438.7 million of which is indebtedness of our subsidiaries that is guaranteed by us. As of December 31, 2001, our subsidiaries had an additional $125.3 million of indebtedness outstanding. Sinking Fund ..................... None. Redemption of Notes at the Option of Omnicom ............ We cannot redeem the notes before July 31, 2007. On or after July 31, 2007 and before July 31, 2022, we may redeem the notes at any time in whole or in part at the initial principal amount at maturity of the notes. On or after July 31, 2022, we may redeem the notes at any time in whole or in part at the initial principal amount at maturity plus accrued contingent additional principal, if any. Purchase of the Notes at the Option of the Holder ............. On each July 31 (or if July 31 is not a business day, the next succeeding business day), from and including July 31, 2003, through July 31, 2031, holders may require us to purchase all or a portion of their notes, with payment on the fourth business day after such date, at the following prices: (1) July 31, 2003 through but not including July 31, 2022 at the initial principal amount at maturity of the notes; and (2) July 31, 2022 through and including July 31, 2031 at the initial principal amount at maturity of the notes plus accrued contingent additional principal, if any. We may choose to pay the purchase price in cash, shares of common stock or a combination of cash and common stock. See "Description of the Notes--Purchase of Notes at the Option of the Holder." When a holder surrenders the notes for repurchase, the repurchase agent may first offer the notes to a financial institution chosen by us to purchase the notes. The designated financial institution will have the option but not the obligation (unless separately agreed to by it and us at the time) to purchase the notes at the repurchase price, which is payable in cash or, if we have previously so elected, in stock. We may, but will not be obligated to, enter into a separate agreement with the financial institution which would compensate it for any such transaction. Change in Control ................ Upon a change in control of Omnicom occurring on or before July 31, 2007, holders may require us to purchase for cash all or a portion of their notes at a price equal to $1,000 per note. In addition, if at least 90% of the notes outstanding immediately prior to the change in control are purchased, we may, within 90 days after the change in control purchase date, at our option, redeem for cash -------------------------------------------------------------------------------- 8 -------------------------------------------------------------------------------- all of the remaining notes at a redemption price equal to $1,000 per note. See "Description of the Notes--Purchase at Option of Holders upon Change in Control." DTC Eligibility .................. The notes were issued only in the form of global securities held in book-entry form. DTC or its nominee will be the sole registered holder of the notes represented by a global security for all purposes under the indenture. Beneficial interests in any such securities will be shown on, and transfers will be effected only 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. See "Description of the Notes--Book-Entry System." Use of Proceeds .................. We will not receive any proceeds from the sale by any selling securityholder of the notes or the common stock issuable upon conversion and/or redemption of the notes. See "Use of Proceeds." Trading .......................... The notes sold in the initial private placements are eligible for trading in the PORTAL system. The notes sold using this prospectus, however, will no longer be eligible for trading in the PORTAL system. We do not intend to list the notes on any other national securities exchange or automated quotation system. Our common stock is traded on the New York Stock Exchange under the symbol "OMC". -------------------------------------------------------------------------------- 9 RISK FACTORS RELATING TO THE NOTES You should carefully consider the following information with the other information contained in or incorporated by reference into this prospectus before purchasing the notes. The Lack of Covenants Applicable to the Notes May Not Afford Protection Under Some Circumstances The holders of notes may require us to purchase the notes upon the occurrence of certain change-in-control events described under "Description of the Notes -- Purchase at Option of Holders upon Change in Control." However, we could, in the future, enter into certain transactions, including certain recapitalizations, that would not constitute a change in control with respect to the change in control purchase feature of the notes but that would increase the amount of our (or our subsidiaries') outstanding indebtedness. This purchase right would also not restrict us from incurring indebtedness or effecting extraordinary dividends. Further, the notes do not afford a holder protection under maintenance or other covenants relating to our consolidated financial position or results of operations. An Active Trading Market for the Notes May Not Develop The notes comprise a new issue of securities for us for which there is currently no public market. The notes will not be listed on any securities exchange or included in any automated quotation system. If the notes are traded after their initial issuance, they may trade at a discount, depending on prevailing interest rates, the market for similar securities, the price of our common stock, our performance and other factors. We do not know whether an active trading market will develop for the notes. To the extent that an active trading market does not develop, the price at which you may be able to sell the notes, if at all, may be less than the price you pay for them. In addition, the notes have a number of features, including conditions to conversion, which, if not met, could result in a holder receiving less than the value of the common stock into which a note is otherwise convertible. These features could adversely affect the value and the trading prices for the notes. Our Holding Company Structure Results in Structural Subordination and May Affect Our Ability to Make Payments on the Notes The notes are obligations exclusively of Omnicom. We are a holding company and, accordingly, substantially all of our operations are conducted through our subsidiaries. As a result, our cash flow and our ability to make payments on our debt, including the notes, are dependent upon the earnings of our subsidiaries. In addition, we are dependent on the distribution of earnings, loans or other payments by our subsidiaries to us. Our subsidiaries are separate and distinct legal entities. Our subsidiaries have no obligation to pay any amounts due on the notes or to provide us with funds for our payment obligations, whether by dividends, distributions, loans or other payments. In addition, any payment of dividends, distributions, loans or advances by our subsidiaries to us could be subject to statutory or contractual restrictions. Payments to us by our subsidiaries will also be contingent upon our subsidiaries' earnings and business considerations. Because we are a holding company, the claims of creditors of our subsidiaries will have a priority over our equity rights and the rights of our creditors, including the holders of notes, to participate in the assets of the subsidiary upon the subsidiary's liquidation. You Should Consider the United States Federal Income Tax Consequences of Owning the Notes The notes will be characterized as indebtedness for United States federal income tax purposes. Accordingly, you will be required to include in your income interest with respect to the notes. The notes constitute contingent payment debt instruments and will accrue tax original issue discount. As a result, you will be required to include amounts in income, as ordinary income, in advance of the receipt of the cash, or other property, attributable thereto. Pursuant to our determination of the tax original issue discount on the notes, you will recognize gain or loss on the sale, purchase by us at your option, conversion or redemption of a note in an amount equal to the difference between the amount realized on such a transaction, including the fair market value of any common stock received upon conversion or otherwise, and your adjusted tax basis in the note. Any gain so recognized by you generally will be ordinary interest income; any loss will be ordinary 10 loss to the extent of the interest previously included in income and, thereafter, capital loss. However, it is possible that holders may be precluded by certain rules regarding recapitalizations from recognizing any capital loss with respect to a conversion or redemption of the notes in exchange for shares of our stock. Holders should consult their tax advisors regarding the deductibility of any such capital loss. A summary of the federal income tax consequences of ownership of the notes is described in this prospectus under the heading "Federal Income Tax Considerations." We May Not Have the Ability to Raise the Funds Necessary to Finance the Purchase at the Option of the Holder or the Change in Control Purchase and the Amount You Receive Upon Redemption, Purchase or a Change of Control May Be Less Than What You Paid for the Notes On each July 31 (or if July 31 is not a business day, the next succeeding business day), from and including July 31, 2003 through and including July 31, 2031, and upon a change in control of Omnicom occurring on or before July 31, 2007, holders of the notes have the right to require us to purchase their notes. We have the right to elect to pay the purchase price in shares of our common stock and to designate a financial institution to satisfy, at its option, our purchase obligation. However, if we fail or are unable to elect to pay in stock or to so designate a financial institution, we may not have sufficient funds at those times to make any required purchase of notes. In addition, corporate events involving fundamental changes to our capital structure, such as leveraged recapitalizations that would increase the level of our indebtedness or that of our subsidiaries, would not necessarily constitute a change in control for these purposes. Furthermore, the notes were sold by the initial purchasers in the private placements at a premium to the initial principal amount at maturity. As a result, at maturity or at any time that you elect to have us, or any financial institution we may designate, purchase your notes, you will receive a cash payment in an amount less than you originally paid for the notes unless contingent additional principal has accrued in an amount sufficient to equal the amount paid by you for the notes at the time of such purchase. See "Description of the Notes -- Purchase of the Notes at Option of Holder" and "-- Purchase at Option of Holders Upon Change in Control." 11 SELECTED CONSOLIDATED HISTORICAL FINANCIAL INFORMATION The following table sets forth our selected consolidated financial data and should be read in conjunction with our consolidated financial statements incorporated into this prospectus by reference.

We are not aware of any restrictions on our present or future ability to pay dividends. However, in connection with certain borrowing facilities entered into by us and our subsidiaries, we are subject to certain covenants requiring that we satisfy certain financial tests in order to pay dividends. We have one billion authorized shares of common stock, par value $0.15 per share, of which 187.8 million shares were outstanding on April 8, 2002. 13 CAPITALIZATION The following table sets forth our consolidated capitalization as of December 31, 2001 on an actual basis and on an as adjusted basis to give effect to the sale of the notes and the application of the net proceeds from the sale of the notes described in footnote 1 below. You should read this table together with our financial statements and related notes and other financial and operating data included elsewhere in or incorporated by reference into this prospectus.

As our commercial paper balances, which are included in our long-term debt as disclosed in the notes to our consolidated financial statements for the year ended December 31, 2001, were lower at the end of 2001 than they were at the time the notes were sold, we have adjusted accounts payable in the above table. Convertible debentures and treasury stock were increased to reflect the sale of the notes and the use of proceeds to repurchase 3.0 million shares. (2) Outstanding common stock as of December 31, 2001 of 190.6 million shares excludes shares issuable upon exercise of options, conversion of convertible debt (including 8.2 million shares reserved for issuance upon conversion of the notes) and certain other events. See Note 1 to our consolidated financial statements for the year ended December 31, 2001. (3) We used a portion of the net proceeds to repurchase 3.0 million shares of our common stock at a price of $93.54 per share. The effect of the repurchase was to increase treasury shares and to decrease outstanding shares. 14 DESCRIPTION OF THE NOTES We issued the notes under a senior indenture between us and JPMorgan Chase Bank, as trustee. The following summarizes the material provisions of the notes and the indenture. The following summary is not complete and is subject to, and qualified by reference to, all of the provisions of the notes and the indenture. As used in this description, the words "we," "us," "our" and "Omnicom" do not include any current or future subsidiary of Omnicom. The indenture does not contain any financial covenants or any restrictions on the payment of dividends or the issuance or purchase of our securities. The indenture contains no covenants or other provisions to give protection to the holders of the notes in the event of a highly leveraged transaction or a change in control, except to the extent described under "--Purchase at Option of Holders upon Change in Control." General The notes are limited to $900,000,000 aggregate initial principal amount at maturity. The notes will mature July 31, 2032. Before July 31, 2022, the principal amount at maturity of a note will be equal to the initial principal amount at maturity of the note. On or after July 31, 2022, if, for the last 20 trading days preceding July 31, 2022, the average conversion value of a note is greater than the initial principal amount at maturity but less than or equal to 220% of the initial principal amount at maturity, then the principal amount at maturity of a note will be equal to the conversion value of the note on July 31, 2022, but in no event greater than 200% the initial principal amount at maturity. If that conversion value exceeds 220% of the initial principal amount at maturity then the principal amount at maturity will equal the initial principal amount at maturity. Contingent additional principal is the difference between the $1,000 initial principal amount at maturity of a note and the principal amount at maturity, if any. Contingent additional principal will be calculated on a semi-annual bond equivalent basis, using a 360-day year composed of twelve 30-day months. The conversion value of a note as of any date of determination will equal the sale price per share of our common stock on such determination date multiplied by the number of shares of common stock then issuable upon conversion of a note. The notes will be payable at the office of the paying agent, which initially will be an office or agency of the trustee, or an office or agency maintained by us for such purpose, in the Borough of Manhattan, The City of New York. We will not pay any interest on the notes prior to maturity unless contingent cash interest becomes payable. Each note was issued at an initial principal amount at maturity of $1,000 per note. Although the notes were not initially offered at a discount, they constitute contingent payment debt instruments. As a result, the notes are deemed to have been issued with original issue discount for United States federal income tax purposes, referred to as tax original issue discount. We intend to compute and report accruals of the tax original issue discount based upon an overall yield of 6.69% per year, computed on a semiannual bond equivalent basis, which we have determined represents the yield we would pay on noncontingent, nonconvertible, fixed-rate debt with terms otherwise similar to the notes. See "Federal Income Tax Considerations." Maturity, conversion, purchase by us at the option of the holder or redemption of a note will cause contingent additional principal, if any, and contingent cash interest, if any, to cease to accrue on such note. We may not reissue a note that has matured or been converted, purchased by us at your option, redeemed or otherwise cancelled. Notes may be presented for conversion at the office of the conversion agent and for exchange or registration of transfer at the office of the registrar. The conversion agent and the registrar will initially be the trustee. We will not charge a service fee for any exchange or registration of transfer of notes. However, we may require the holder to pay any tax, assessment or other governmental charge payable as a result of such transfer or exchange. Because we sold the notes to the initial purchasers, and the initial purchasers resold the notes, at a higher price than the initial principal amount at maturity, you may receive less than you originally paid to purchase notes upon redemption or repurchase as described below. 15 Ranking of the Notes The notes are senior unsecured obligations. The notes rank equal in right of payment to all of our existing and future senior unsecured indebtedness. However, we are a holding company and the notes are effectively subordinated to all existing and future obligations of our subsidiaries and to our obligations that are secured, to the extent of the security. See "Risk Factors -- Our Holding Company Structure Results in Structural Subordination and May Affect Our Ability to Make Payments on the Notes." As of December 31, 2001, we had $1,424.3 million of indebtedness outstanding, all of which is unsecured, $985.6 million of which is issued by us and $438.7 million of which is indebtedness of our subsidiaries that is guaranteed by us. As of December 31, 2001, our subsidiaries had an additional $125.3 million of indebtedness outstanding. Book-Entry System The notes were only issued in the form of global securities held in book-entry form. DTC or its nominee is the sole registered holder of the notes for all purposes under the indenture. Owners of beneficial interests in the notes represented by the global securities hold their interests pursuant to the procedures and practices of DTC. As a result, beneficial interests in any such securities are 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, including any right to convert or require purchase of their interests in the notes, in accordance with the procedures and practices of DTC. Beneficial owners are not holders and are not entitled to any rights provided to the holder of notes under the global securities or the indenture. Omnicom and the trustee, and any of their respective agents, may treat DTC as the sole holder and registered owner of the global securities. Exchange of Global Securities Notes represented by a global security are exchangeable for certificated securities with the same terms only if: o DTC is unwilling or unable to continue as depositary or if DTC ceases to be a clearing agency registered under the Exchange Act and a successor depositary is not appointed by us within 90 days, o we decide to discontinue use of the system of book-entry transfer through DTC (or any successor depositary), or o a default under the indenture occurs and is continuing. DTC has advised us that it is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC facilitates the settlement of transactions among its participants through electronic computerized book-entry changes in participants' accounts, eliminating the need for physical movement of securities certificates. DTC's participants include securities brokers and dealers, including the initial purchasers, banks, trust companies, clearing corporations and other organizations, some of whom and/or their representatives own DTC. Access to DTC's book-entry system is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly. Conversion Rights Holders may surrender notes for conversion into shares of our common stock only if at least one of the conditions described below is satisfied. In addition, a note for which a holder has delivered a purchase notice or a change in control purchase notice requiring us to purchase the note may be surrendered for conversion only if such notice is withdrawn in accordance with the indenture. 16 The initial conversion rate is 9.09 shares per $1,000 initial principal amount at maturity of the notes, subject to adjustment only upon the occurrence of the events described below. The conversion rate will not be adjusted for accrued contingent principal, if any. A holder of a note otherwise entitled to a fractional share will receive cash in an amount equal to the value of such fractional share based on the sale price, as defined below under "--Purchase of Notes at the Option of the Holder," on the trading day immediately preceding the conversion date. If contingent cash interest is payable to holders of notes during any particular six-month period, and any notes are converted after the applicable record date, those notes, upon surrender, must be accompanied by funds equal to the amount of contingent cash interest payable on the principal amount of notes so converted, unless those notes have been called for redemption, in which case no such payment shall be required. The ability to surrender notes for conversion will expire at the close of business on July 31, 2032. To convert a note into shares of common stock, a holder must: o complete and manually sign the conversion notice on the back of the note or complete and manually sign a facsimile of the conversion notice and deliver the conversion notice to the conversion agent, o surrender the note to the conversion agent, o if required by the conversion agent, furnish appropriate endorsements and transfer documents, and o if required, pay all transfer or similar taxes. Pursuant to the indenture, the date on which all of the foregoing requirements have been satisfied is the conversion date. If one or more of the conditions to the conversion of the notes has been satisfied, we will promptly notify the holders of notes thereof and use our reasonable best efforts to post this information on our web site or, at our option, otherwise publicly disclose this information. Conversion Based on Common Stock Price Before July 31, 2022, holders may surrender a note for conversion during any calendar quarter commencing after March 31, 2002 if, for the last 20 trading days in the preceding calendar quarter, the average conversion value of the note is greater than or equal to a specified percentage, initially 125% and increasing 5% per quarter up to a maximum of 220%, of the initial principal amount at maturity of the note. If the foregoing condition is satisfied at any time after July 31, 2003, and before July 31, 2022, then the notes will be convertible at any time at the option of the holder, through maturity. On or after July 31, 2022, holders may surrender a note for conversion during any calendar quarter if, for the last 20 trading days in the preceding calendar quarter, the average conversion value of the note is greater than or equal to 110% of the principal amount at maturity of the note. If the foregoing condition is satisfied, then the notes will thereafter be convertible at any time at the option of the holder, through maturity. Conversion Based on Credit Ratings Holders may also surrender a note for conversion at the then-applicable conversion rate at any time after the credit rating assigned to the notes is reduced to Baa3 or lower by Moody's Investors Service, Inc. or BBB or lower by Standard & Poor's Ratings Services. Conversion upon Notice of Redemption A holder may surrender for conversion a note called for redemption at any time prior to the close of business on the second business day prior to the redemption date, even if it is not otherwise convertible at that time. A note for which a holder has delivered a purchase notice or a change in control purchase notice as described below requiring us to purchase the note may be surrendered for conversion only if such notice is withdrawn in accordance with the indenture. Conversion upon Occurrence of Specified Corporate Transactions If we elect to o distribute to all holders of common stock certain rights entitling them to purchase, for a period expiring within 60 days, common stock at less than the quoted price at the time, or 17 o distribute to all holders of our common stock assets, debt securities or certain rights to purchase our securities, which distribution has a per share value as determined by our board of directors exceeding 15% of the closing price of the common stock on the day preceding the declaration date for such distribution, we must notify the holders of notes at least 20 days prior to the ex-dividend date for such distribution. Once we have given such notice, holders may surrender their notes for conversion at any time until the earlier of the close of business on the business day prior to the ex-dividend date or our announcement that such distribution will not take place. In addition, if we are party to a consolidation, merger or binding share exchange pursuant to which our common stock would be converted into cash, securities or other property, a holder may surrender notes for conversion at any time from and after the date which is 15 days prior to the anticipated effective date for the transaction until 15 days after the actual effective date of such transaction. Conversion Rate Adjustments and Delivery of Common Stock The initial conversion rate is 9.09 of our common shares for each $1,000 initial principal amount at maturity of the notes. The conversion rate will not be adjusted for accrued contingent additional principal, if any, or contingent cash interest, if any. When a holder surrenders notes for conversion, the conversion agent may first offer the notes to a financial institution chosen by us for exchange in lieu of conversion. The designated institution will have the option, but not the obligation (unless separately agreed to by it and us at the time), to agree to exchange those notes for the number of shares of our common stock that the holder of those notes would have been entitled to receive upon conversion, plus cash for any fractional shares. We may, but will not be obligated to, enter into a separate agreement with the financial institution which would compensate it for any such transaction. As soon as practicable following the conversion date, the designated institution or we, as the case may be, will deliver through the conversion agent a certificate for the number of full shares of common stock into which any note is converted, together with any cash payment for fractional shares. Delivery to the holder of the full number of shares of common stock into which the note is convertible, together with any cash payment for such holder's fractional shares, will be deemed to satisfy our obligation to pay the principal amount at maturity of the note whether made by us or by the designated institution. For a discussion of the tax treatment of a holder receiving common stock upon conversion, see "Federal Income Tax Considerations--Disposition or Conversion." We will adjust the conversion rate for: o dividends or distributions on our common stock payable in our common stock or other capital stock, o subdivisions, combinations or certain reclassifications of our common stock, o distributions to all holders of common stock of certain rights to purchase common stock for a period expiring within 60 days at less than the sale price at the time, and o distributions to those holders of our assets or debt securities or certain rights to purchase our securities (excluding cash dividends or other cash distributions from current or retained earnings unless the annualized amount thereof per share exceeds 5% of the sale price of the common stock on the day preceding the date of declaration of such dividend or other distribution). However, no adjustment need be made if holders may participate in the transaction without conversion or in certain other cases. The indenture permits us to increase the conversion rate from time to time at out option. If we are party to a consolidation, merger or binding share exchange pursuant to which our common stock is converted into cash, securities or other property, at the effective time of the transaction, the right to convert a note into shares of our common stock will be changed into a right to convert it into the kind and amount of securities, cash or other property of Omnicom or another person which the holder would have received if the holder had converted the holder's note immediately prior to the transaction. If the transaction also constitutes a "change in control," as defined below, the holder will be able to require us to purchase all or a portion of its notes as described under "--Purchase at Option of Holders upon Change in Control." 18 In the event of: o a taxable distribution to holders of common stock which results in an adjustment of the conversion rate, or o an increase in the conversion rate at our discretion, the holders of the notes may, in certain circumstances, be deemed to have received a distribution subject to United States federal income tax as a dividend. See "Federal Income Tax Considerations--Constructive Dividend." Contingent Cash Interest We will pay contingent cash interest to the holders of notes during any six-month period from August 1 to January 31, and from February 1 to July 31, commencing August 1, 2007 if the average market price of a note for a five trading day measurement period preceding the applicable six-month period equals 120% or more of the initial principal amount at maturity of the note. Each five trading day measurement period will end on the second trading day immediately preceding the applicable six-month period. However, if we declare a dividend for which the record date will occur prior to the applicable six-month period but for which the payment date will occur during the applicable six-month period, the five trading day measurement period will instead end on the second trading day immediately preceding that record date. For any six-month period, the amount of contingent cash interest per note will be equal to the amount of regular cash dividends paid by us per share on our common stock multiplied by the number of shares then issuable upon conversion of a note. Contingent cash interest, if any, will accrue and be payable to holders of notes as of the record date for the related common stock dividend during the relevant six-month period. Such payments will be made on the payment date of the related common stock dividend. If we do not pay regular cash dividends, holders will not be entitled to any contingent cash interest. Regular cash dividends are quarterly or other periodic cash dividends on our common stock as declared by our board of directors as part of its cash dividend payment practices and that are not designated by them as extraordinary or special or other nonrecurring dividends. The market price of a note on any date of determination means the average of the secondary market bid quotations per note obtained by the bid solicitation agent for $10.0 million principal amount at maturity of notes at approximately 4:00 p.m., New York City time, on such determination date from three independent nationally recognized securities dealers we select, provided that if o at least three such bids are not obtained by the bid solicitation agent, or o in our reasonable judgment, the bid quotations are not indicative of the secondary market value of the notes, then the market price of the note will equal (1) the then applicable conversion rate of the notes multiplied by (2) the average sale price of our common stock on the five trading days ending on such determination date, appropriately adjusted. The bid solicitation agent will be initially JPMorgan Chase Bank. We may change the bid solicitation agent, but the bid solicitation agent will not be our affiliate. The bid solicitation agent will solicit bids from securities dealers that are believed by us to be willing to bid for the notes. We will determine every six months, commencing August 1, 2007, whether the conditions to the payment of contingent cash interest have been satisfied and, if so, we will promptly notify the holders of notes thereof and use our reasonable best efforts to post this information on our web site or, at our option, otherwise publicly disclose this information. We may unilaterally increase the amount of contingent cash interest we pay or pay interest or other amounts we are not obligated to pay, but we will have no obligation to do so. 19 Redemption of Notes at the Option of Omnicom No sinking fund is provided for the notes. We cannot redeem the notes before July 31, 2007. On or after July 31, 2007 and before July 31, 2022, we may, at our option, redeem the notes for cash at any time in whole or from time to time in part at the initial principal amount at maturity of the notes. On or after July 31, 2022, we may redeem the notes at any time in whole or in part at the initial principal amount at maturity plus accrued contingent additional principal, if any. We will give not less than 30 days nor more than 60 days notice of redemption by mail to holders of notes. Notes called for redemption will be convertible by the holder, even if the other conditions described under "--Conversion Rights" have not occurred, until the close of business on the second business day prior to the redemption date. The notes will be redeemable in integral multiples of $1,000. If less than all of the outstanding notes are to be redeemed, the trustee will select the notes to be redeemed. In this case, the trustee may select the notes by lot, pro rata or by any other method the trustee considers fair and appropriate. If a portion of a holder's notes is selected for partial redemption and the holder converts a portion of the notes, the converted portion will be deemed to be the portion selected for redemption. Purchase of Notes at the Option of the Holder On each July 31 (or if July 31 is not a business day, the next succeeding business day), from July 31, 2003 through July 31, 2031, holders may require us to purchase any outstanding note for which the holder has properly delivered a written purchase notice, subject to certain additional conditions, including that such notice is not withdrawn by the close of business on the next business day, at the following prices: o July 31, 2003 through but not including July 31, 2022 at the initial principal amount at maturity of the note, and o July 31, 2022 through July 31, 2031 at the initial principal amount at maturity of the note plus accrued contingent additional principal, if any. Holders may submit their notes for purchase to the paying agent at any time from the opening of business on the date that is 20 business days prior to July 31 of each year, or, if such day is not a business day, the next succeeding business day, until the close of business on such date. The purchase price will be payable, at our option, on the fourth business day following the applicable purchase date in cash, shares of our common stock or any combination thereof. When a holder surrenders the notes for purchase, the purchase agent may first offer the notes to a financial institution chosen by us to purchase the notes. The designated financial institution will have the option, but not the obligation (unless separately agreed to by it and us at the time) to purchase the notes at the purchase price, which is payable in cash or, if we have previously so elected, in stock. We may, but will not be obligated to, enter into a separate agreement with the financial institution which would compensate it for any such transaction. We will be required to give notice on a date not less than 20 business days prior to each applicable purchase date to all holders at their addresses shown in the register of the registrar, and to beneficial owners as required by applicable law, stating among other things: o whether the purchase price will be paid in cash or common stock or any combination thereof, specifying the percentage of each, o if we elect to pay in common stock, the method of calculating the market price of common stock, and o the procedures that holders must follow to require us to purchase their notes. The purchase notice given by each holder electing to require us to purchase notes shall be given so as to be received by the paying agent no later than the close of business on July 31 of each year, or, if such day is not a business day, the next succeeding business day, and must state: o the certificate numbers of the holder's notes to be delivered for purchase, o the portion of the initial principal amount at maturity of notes to be purchased, which must be $1,000 or an integral multiple of $1,000, and 20 o that the notes are to be purchased pursuant to the applicable provisions of the notes. A holder may withdraw any purchase notice by delivering a written notice of withdrawal to the paying agent prior to the close of business on the business day next succeeding the date on which the purchase notice is required to be delivered. The notice of withdrawal shall state: o the initial principal amount at maturity of the notes being withdrawn, o the certificate numbers of the notes being withdrawn, and o the initial principal amount at maturity, if any, of the notes that remain subject to the purchase notice. If we elect to pay the purchase price, in whole or in part, in shares of common stock, the number of shares of common stock to be delivered by us, or the designated institution, as the case may be, shall be equal to the portion of the purchase price to be paid in common stock divided by the market price of a share of common stock. For this purpose, the "market price" of our common stock means the average of the sale prices of the common stock for the five trading days ending on (if the third business day prior to the applicable purchase date is a trading day or, if not, then on the last trading day prior to) the third business day prior to the applicable purchase date, appropriately adjusted to take into account the occurrence, during the period commencing on the first of the trading days during the relevant five trading day period and ending on the purchase date, of certain events that would result in an adjustment of the conversion rate with respect to the common stock. The "sale price" of our common stock on any date means the closing per share sale price (or if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) on such date as reported in composite transactions for the principal United States securities exchange on which the common stock is then traded or, if the common stock is not listed on a United States national or regional securities exchange, as reported by the National Association of Securities Dealers Automated Quotation System or by the National Quotation Bureau Incorporated or otherwise as provided in the indenture. Because the market price of the common stock is determined prior to the applicable purchase date, holders of notes bear the market risk with respect to the value of the common stock to be received from the date such market price is determined to such purchase date. We, or the designated institution, as the case may be, may pay the purchase price or any portion of the purchase price in common stock only if the information necessary to calculate the market price is published in a daily newspaper of national circulation. Upon determination of the actual number of shares of common stock to be issued for each $1,000 initial principal amount at maturity of notes in accordance with the foregoing provisions, we will promptly notify the holders of notes thereof and use our reasonable best efforts to post this information on our web site or, at our option, otherwise publicly disclose this information. We, or the designated institution, as the case may be, will pay cash based on the market price for all fractional shares of common stock in the event we elect to deliver common stock in payment, in whole or in part, of the purchase price. In addition to the above conditions, our right, or the right of the designated institution, as the case may be, to purchase notes, in whole or in part, with common stock is subject to our satisfying various conditions, including: o listing such common stock on the principal United States securities exchange on which our common stock is then listed or, if not so listed, on Nasdaq, o the registration of the common stock under the Securities Act and the Exchange Act, if required, and o any necessary qualification or registration under applicable state securities law or the availability of an exemption from such qualification and registration. If these conditions are not satisfied with respect to a holder prior to the close of business on the purchase date, we, or the designated institution, as the case may be, will be required to pay the purchase price of the notes to the holder entirely in cash. See "Federal Income Tax Considerations--Disposition or Conversion." 21 Neither we nor the designated institution may change the form or components or percentages of components of consideration to be paid for the notes once we have given the notice that we are required to give to holders of notes, except as described in the first sentence of this paragraph. In connection with any purchase offer, we, or the designated institution, as the case may be, will o comply with the provisions of any tender offer rules under the Exchange Act which may then be applicable, and o file a Schedule TO or any other required schedule under the Exchange Act, if required. Our obligation, or the obligation of the designated institution, as the case may be, to pay the purchase price for a note for which a purchase notice has been delivered and not validly withdrawn is conditioned upon the holder delivering the note, together with necessary endorsements, to the paying agent at any time after delivery of the purchase notice. Payment of the purchase price for the note will be made promptly following the later of the purchase date or the time of delivery of the note. If on any purchase date, the notes are purchased in accordance with the terms of the indenture, then, immediately after the purchase date, whether or not the note is delivered to the paying agent, the holder exercising its right to require Omnicom to purchase such notes will cease to be entitled to contingent additional principal or conditional additional interest, if any and all other rights of that holder shall terminate, other than the right to receive the purchase price upon delivery of the note. Our ability to purchase notes may be limited by the terms of our then-existing borrowing agreements. We may not purchase any notes for cash at the option of holders if an event of default with respect to the notes has occurred and is continuing, other than a default in the payment of the purchase price with respect to such notes. Purchase at Option of Holders upon Change in Control In the event of a change in control occurring on or prior to July 31, 2007, each holder will have the right, at the holder's option, subject to the terms and conditions of the indenture, to require us to purchase for cash all or any portion of the holder's notes, at a price equal to $1,000 per note. We will be required to purchase the notes as of the date that is 35 business days after the occurrence of such change in control. We refer to this date as the "change in control purchase date." In addition, if at least 90% in aggregate principal amount of the notes outstanding immediately prior to the change of control are purchased on the change in control purchase date, we may, within 90 days following the change in control purchase date, at our option, redeem all of the remaining notes at a redemption price equal to $1,000 per note. Within 15 days after the occurrence of a change in control, we must mail to the trustee and to all holders of notes at their addresses shown in the register of the registrar and to beneficial owners as required by applicable law a notice regarding the change in control, which notice must state: o the events causing the change in control, o the date of the change in control, o the last date on which a holder may exercise the purchase right, o the change in control purchase price, o the change in control purchase date, o the name and address of the paying agent and the conversion agent, o the conversion rate and any adjustments to the conversion rate, o that notes with respect to which a change in control purchase notice is given by the holder may be converted, if otherwise convertible, only if the change in control purchase notice has been withdrawn in accordance with the terms of the indenture, and o the procedures that holders must follow to exercise these rights. 22 To exercise this right, the holder must deliver a written notice so as to be received by the paying agent no later than the close of business on the third business day prior to the purchase date. The required purchase notice upon a change in control must state: o the certificate numbers of the notes to be delivered by the holder, o the initial principal amount at maturity of notes to be purchased, which must be $1,000 or an integral multiple of $1,000, and o that we are to purchase such notes pursuant to the applicable provisions of the notes. A holder may withdraw any change in control purchase notice by delivering to the paying agent a written notice of withdrawal prior to the close of business on the change in control purchase date. The notice of withdrawal must state: o the initial principal amount at maturity of the notes being withdrawn, o the certificate numbers of the notes being withdrawn, and o the initial principal amount at maturity, if any, of the notes that remain subject to a change in control purchase notice. Our obligation to pay the change in control purchase price for a note for which a change in control purchase notice has been delivered and not validly withdrawn is conditioned upon delivery of the note, together with necessary endorsements, to the paying agent at any time after the delivery of such change in control purchase notice. Payment of the change in control purchase price for such note will be made promptly following the later of the change in control purchase date or the time of delivery of such note. If on any change in control purchase date, notes are purchased in accordance with the terms of the indenture, then, immediately after the change in control purchase date, whether or not the note is delivered to the paying agent, the holder exercising its right to require Omnicom to purchase such notes will cease to be entitled to contingent additional principal or contingent additional interest, if any, and all other rights of that holder shall terminate, other than the right to receive the change in control purchase price upon delivery of the note. Under the indenture, a "change in control" of Omnicom is deemed to have occurred at such time as: o any person, including its affiliates and associates, other than Omnicom, its subsidiaries or their employee benefit plans, files a Schedule 13D or TO (or any successor schedules, forms or reports under the Exchange Act) disclosing that such person has become the beneficial owner of 50% or more of the voting power of our common stock or other capital stock into which our common stock is reclassified or changed, with limited exceptions, or o there shall be consummated any consolidation, merger or share exchange of Omnicom pursuant to which the common stock would be converted into cash, securities or other property, in each case other than a consolidation, merger or share exchange of Omnicom in which the holders of our common stock immediately prior to the consolidation, merger or share exchange have, directly or indirectly, at least a majority of the total voting power in the aggregate of all classes of ordinary voting stock of the continuing or surviving corporation immediately after the consolidation, merger or share exchange. The indenture does not permit our board of directors to waive our obligation to purchase notes at the option of holders in the event of a change in control. In connection with any purchase offer in the event of a change in control, we will: o comply with the provisions of any tender offer rules under the Exchange Act which may then be applicable, and o file a Schedule TO or any other required schedule under the Exchange Act, if required. The change in control purchase feature of the notes may in certain circumstances make more difficult or discourage a takeover of Omnicom. The change in control purchase feature, however, is not the result of our knowledge of any specific effort: o to accumulate shares of our common stock, 23 o to obtain control of Omnicom by means of a merger, tender offer, solicitation or otherwise, or o part of a plan by management to adopt a series of anti-takeover provisions. Instead, the change in control purchase feature is a standard term contained in other notes offerings that have been marketed by the initial purchasers and other investment banks. The terms of the change in control purchase feature resulted from negotiations between the initial purchasers and us. We could, in the future, enter into certain transactions, including certain recapitalizations, that would not constitute a change in control with respect to the change in control purchase feature of the notes but that would increase the amount of our (or our subsidiaries') outstanding indebtedness. See "Risk Factors Relating to the Notes--The Lack of Covenants Applicable to the Notes May Not Afford Protection Under Some Circumstances." We may not purchase notes at the option of holders upon a change in control if there has occurred and is continuing an event of default with respect to the notes, other than a default in the payment of the change in control purchase price with respect to the notes. Events of Default The following will be events of default for the notes: (1) default in payment of the principal amount at maturity, contingent additional principal, redemption price, purchase price or change in control purchase price with respect to any note when such becomes due and payable, (2) default in payment of any contingent cash interest, which default continues for 30 days, (3) our failure to comply with any of our other agreements in the notes or the indenture upon receipt by us of notice of such default by the trustee or by holders of not less than 25% in aggregate principal amount at maturity of the notes then outstanding and our failure to cure (or obtain a waiver of) such default within 60 days after receipt of such notice, (4) (A) our failure to make any payment by the end of any applicable grace period after maturity of indebtedness, which term as used in the indenture means obligations (other than nonrecourse obligations) of Omnicom 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 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 us by the trustee or to us and the trustee by the holders of not less than 25% in aggregate principal amount at maturity of the notes then outstanding; however, if any such failure or acceleration referred to in (A) or (B) above shall cease or be cured, waived, rescinded or annulled, then the event of default by reason thereof shall be deemed not to have occurred, or (5) certain events of bankruptcy or insolvency affecting us or certain of our subsidiaries. If an event of default shall have happened and be continuing, either the trustee or the holders of not less than 25% in aggregate principal amount at maturity of the notes then outstanding may declare the initial principal amount at maturity of the notes, plus any accrued and unpaid contingent cash interest and contingent additional principal through the date of such declaration, to be immediately due and payable. In the case of certain events of bankruptcy or insolvency of Omnicom, the initial principal amount at maturity of the notes plus accrued and unpaid contingent cash interest and contingent additional principal shall automatically become immediately due and payable. Mergers and Sales of Assets The indenture provides that we may not consolidate with or merge into any person or convey, transfer or lease our properties and assets substantially as an entirety to another person, unless, among other things: 24 o the resulting, surviving or transferee person is a corporation organized under the laws of the United States, any state thereof or the District of Columbia and such entity assumes all our obligations under the notes and the indenture, and o we or such successor entity shall not immediately thereafter be in default under the indenture. Upon the assumption of our obligations by such corporation in such circumstances, subject to certain exceptions, we shall be discharged from all obligations under the notes and the indenture. Although such transactions are permitted under the indenture, certain of the foregoing transactions occurring on or prior to July 31, 2007 could constitute a change in control of Omnicom, permitting holders to require us to purchase their notes as described above. Modification We and the trustee may modify or amend the indenture or the notes with the consent of the holders of not less than a majority in aggregate principal amount at maturity of the notes then outstanding. However, the consent of the holders of each outstanding note would be required to: o alter our obligation to pay contingent cash interest (except that we may increase the amount thereof without the consent of the trustee or the holders), o make any note payable in money or securities other than that stated in the note, o alter the stated maturity of any note, o reduce the principal amount at maturity, contingent additional principal, redemption price, purchase price or change in control purchase price with respect to any note, o make any change that adversely affects the right of a holder to receive shares of common stock upon surrendering a note for conversion, o make any change that adversely affects the right to require us to purchase a note, o impair the right to institute suit for the enforcement of any payment with respect to, or conversion of, the notes, and o change the provisions in the indenture that relate to modifying or amending the indenture. Without the consent of any holder of notes, we and the trustee may enter into supplemental indentures for any of the following purposes: o to evidence a successor to us and the assumption by that successor of our obligations under the indenture and the notes, o to add covenants for the benefit of the holders of the notes or to surrender any right or power conferred upon us, o to secure our obligations in respect of the notes, o to make any changes or modifications to the indenture necessary in connection with the registration of the notes under the Securities Act and the qualification of the notes under the Trust Indenture Act of 1939 as contemplated by the indenture, o to cure any ambiguity or inconsistency in the indenture, or o to make any change that does not adversely affect the rights of any holder of the notes. The holders of a majority in aggregate principal amount at maturity of the notes then outstanding may, on behalf of the holders of all notes: o waive compliance by us with restrictive provisions of the indenture, as detailed in the indenture; and 25 o waive any past default under the indenture and its consequences, except a default in the payment of the principal amount at maturity, contingent additional principal, redemption price, purchase price, change in control purchase price or obligation to deliver common stock upon conversion with respect to any note or in respect of any provision which under the indenture cannot be modified or amended without the consent of the holder of each outstanding note affected. Calculations in Respect of Notes We are responsible for making all calculations called for under the note. See "--Conversion Rights." These calculations include, but are not limited to, determination of the market prices of the note and of our common stock, amounts of tax original issue discount, and amounts of contingent cash interest and contingent additional principal, if any, payable on the note. We will make all these calculations in good faith and, absent manifest error, our calculations will be final and binding on holders of note. We will provide a schedule of our calculations to the trustee, and the trustee is entitled to rely upon the accuracy of our calculations without independent verification. Information Concerning the Trustee JPMorgan Chase Bank, an affiliate of J.P. Morgan Securities Inc., one of the initial purchasers, is the trustee, registrar, paying agent and conversion agent. Governing Law The indenture and the notes will be governed by, and construed in accordance with, the law of the State of New York. Miscellaneous We or our affiliates may from time to time purchase the securities offered in this prospectus which are then outstanding by tender, in the open market or by private agreement. DESCRIPTION OF CAPITAL STOCK The following briefly summarizes the material terms of our capital stock. You should read our certificate of incorporation, a copy of which may be obtained from Omnicom as described under "Where You Can Find More Information," for more detailed information that may be important to you. We are authorized to issue 1.0 billion shares of common stock, par value $0.15 per share, of which 187.8 million shares were outstanding on April 8, 2002, and 7.5 million shares of preferred stock at $1.00 per share, none of which is outstanding. Each share of common stock entitles the holder to one vote for the election of directors and for all other matters to be voted on by holders of our common stock. Holders of common stock may not cumulate their votes in the election of directors. All shares of common stock have equal rights and are entitled to such dividends as may be declared by the board of directors out of funds legally available therefor, but only after payment of dividends required to be paid on any outstanding shares of preferred stock. All shares of common stock share ratably upon liquidation in the assets available for distribution to shareholders after payments to creditors and provision for the preference of any preferred stock. We are not aware of any restrictions on our present or future ability to pay dividends. However, in connection with certain borrowing facilities entered into by us and/or our subsidiaries, we are subject to certain covenants requiring that we satisfy certain financial tests in order to pay dividends. The shares of common stock are not subject to call or assessment, have no preemptive or other subscription rights or conversion rights and cannot be redeemed. We have a classified board of directors and our shareholders can remove a director only by an affirmative two-thirds vote of all outstanding voting shares. A two-thirds vote of all outstanding voting shares is also required to amend our by-laws or some of the provisions of our certificate of incorporation and to change the number of directors comprising the full board. The board of directors has power to amend the by-laws or change the number of directors comprising the full board. 26 We may issue preferred stock in series having whatever rights and preferences the board of directors may determine without the approval of our shareholders. One or more series of preferred stock may be made convertible into common stock at rates determined by the board of directors, and preferred stock may be given priority over common stock in payment of dividends, rights on liquidation, voting and other rights. As of December 31, 2001, we had outstanding $850,000,000 of senior unsecured debentures with a scheduled maturity in 2031, which are convertible into shares of our common stock at a conversion price of $110.01 per share, subject to adjustment in certain events. The transfer agent and registrar for the common stock is ChaseMellon Shareholder Services. The common stock is listed on the New York Stock Exchange under the symbol "OMC." FEDERAL INCOME TAX CONSIDERATIONS This is a summary of certain United States federal income tax considerations relevant to holders of notes. This summary is based upon the Internal Revenue Code of 1986 (which we refer to as the Code), Treasury Regulations, Internal Revenue Service ("IRS") rulings and judicial decisions now in effect, all of which are subject to change, possibly with retroactive effect, or different interpretations. No statutory, regulatory, administrative or judicial authority directly addresses the treatment of the notes or instruments similar to the notes for United States federal income tax purposes. There can be no assurance that the IRS will not challenge one or more of the conclusions described herein, and we have not obtained, nor do we intend to obtain, a ruling from the IRS with respect to the United States federal income tax consequences of acquiring or holding notes. This summary does not purport to deal with all aspects of United States federal income taxation that may be relevant to a holder, such as a holder subject to the alternative minimum tax provisions of the Code. Also, it is not intended to address specific considerations relevant to persons in special tax situations, such as financial institutions, insurance companies, regulated investment companies, tax exempt investors, dealers in securities and currencies, U.S. expatriates or persons holding notes as hedges or as positions in a "straddle," "hedge," "conversion" or other integrated transaction for tax purposes. This summary also does not discuss the tax consequences arising under tax laws other than the federal income tax laws, including the laws of any state, local or foreign jurisdiction. In addition, this summary is limited to original purchasers of notes who acquire notes at the "issue price", as defined below, and who hold the notes and common stock into which the notes may be converted as "capital assets" within the meaning of the federal income tax laws. Persons considering the purchase, ownership, conversion or other disposition of notes should consult their own tax advisors regarding the federal income tax consequences to them in their particular circumstances, and consequences arising under the laws of any state, local or foreign taxing jurisdiction. For purposes of this summary, a "U.S. Holder" is a beneficial owner of the notes who or which is: o a citizen or individual resident of the United States, as defined in Section 7701(b) of the Code, o a corporation, partnership or other entity treated as a corporation for United States federal income tax purposes, created or organized in or under the laws of the United States, any state thereof or the District of Columbia, o an estate if its income is subject to United States federal income taxation regardless of its source, or o a trust if (1) a United States court can exercise primary supervision over its administration and (2) one or more United States persons have the authority to control all of its substantial decisions. Notwithstanding the preceding sentence, certain trusts in existence on August 20, 1996, and treated as a U.S. Holder prior to such date, may also be treated as U.S. Holders. A Non-U.S. Holder is a beneficial owner of notes other than a U.S. Holder. 27 We have been advised by our counsel, Jones, Day, Reavis & Pogue, that, in their opinion, the notes will be treated as debt instruments that are subject to United States federal income tax regulations governing contingent payment debt instruments (which we refer to as the CPDI regulations) for United States federal income tax purposes. Accordingly, pursuant to the terms of the indenture, we and each holder of the notes agree to treat the notes as debt instruments with original issue discount under the CPDI regulations as described below. Original Issue Discount Under the CPDI regulations, for United States federal income tax purposes, U.S. Holders of notes are required to accrue interest income on the notes, regardless of whether the holder uses the cash or accrual method of accounting, in amounts described below for each taxable year the holder holds the note. Accordingly, U.S. Holders may be required to include interest in taxable income in each year in excess of the accruals on the notes for non-tax purposes and in excess of any contingent cash interest payments actually received in that year. The CPDI regulations provide that a U.S. Holder must accrue an amount of ordinary interest income, as original issue discount, for United States federal income tax purposes for each accrual period prior to and including the maturity date of the notes. The amount required to be accrued equals the sum of the daily portions of original issue discount with respect to the note for each day during the taxable year or portion of a taxable year on which the holder holds the note, adjusted if necessary as described below. In general, the daily portion is (1) the sum of the issue price of the note plus all accrued interest, determined without regard to any adjustments to interest accruals described below, and minus the amounts of projected scheduled payments for prior periods at the beginning of each six-month accrual period (as defined below), multiplied by (2) the comparable yield to maturity (as defined below) on the note, divided by (3) the number of days in the accrual period. Under these rules, holders may have to include in gross income increasingly greater amounts of original issue discount in each successive accrual period. Any amount included in income as original issue discount will increase a holder's tax basis in the note. The "issue price" is the initial price at which a substantial amount of notes are sold to investors (excluding bond houses, brokers or similar persons acting in the capacity of underwriters, placement agents or wholesalers) for money. Based on the advice of our counsel, Jones, Day, Reavis & Pogue, we intend to treat the "comparable yield" as the annual yield we would pay, as of the initial issue date, on a fixed-rate nonconvertible debt security with no contingent payments, but with terms and conditions otherwise comparable to those of the notes. Accordingly, we intend to take the position that the comparable yield for the notes is 6.69%, compounded semiannually. The specific yield, however, is not entirely clear. If our determination of the comparable yield were successfully challenged by the IRS, the redetermined yield could be materially greater or less than the comparable yield which we have determined. We are required to furnish annually to the IRS and to certain noncorporate U.S. Holders information regarding the amount of the original issue discount on the notes attributable to that year. We will calculate and report original issue discount on the notes based upon six-month accrual periods ending on the maturity day of the notes. We are also required to furnish to holders a schedule of projected payments which we will use in computing the amounts of original issue discount on the notes. In this schedule, we will include estimates (for purposes of computing the original issue discount only) of payments of contingent cash interest that we will make, and of a payment at maturity, taking into account the conversion feature and the contingent additional principal. Under the CPDI regulations, this schedule must produce the comparable yield. Our determination of the schedule of projected payments will be set forth in the indenture. For United States federal income tax purposes, a U.S. Holder must use the comparable yield and the schedule of projected payments in determining its interest accruals, and the adjustments thereto described below, in respect of the notes, unless such U.S. Holder timely discloses and justifies the use of other estimates to the IRS. A U.S. Holder that determines its own comparable yield or schedule of projected payments must also establish that our comparable yield or schedule of projected payments is unreasonable. THE COMPARABLE YIELD AND PROJECTED PAYMENT SCHEDULE ARE NOT DETERMINED FOR ANY PURPOSE OTHER THAN FOR DETERMINATION OF YOUR INTEREST ACCRUALS AND ADJUSTMENTS THEREOF IN RESPECT OF THE NOTES FOR U.S. FEDERAL INCOME TAX PURPOSES AND DO NOT CONSTITUTE A PROJECTION OR REPRESENTATION REGARDING THE ACTUAL AMOUNTS PAYABLE TO HOLDERS OF NOTES. 28 Adjustments to Interest Accruals on the Notes If, during any taxable year, a U.S. Holder receives actual payments with respect to the notes for that taxable year that in the aggregate exceed the total amount of projected payments for that taxable year, and/or the amount of a future contingent payment is established in an amount greater than the projected amount, the U.S. Holder will incur a "positive adjustment" under the CPDI regulations. If a U.S. Holder receives in a taxable year actual payments with respect to the notes for that taxable year that in the aggregate were less than the amount of projected payments for that taxable year, and/or the amount of a future contingent payment is established in an amount less than the projected amount, the U.S. Holder will incur a "negative adjustment" under the CPDI regulations. The difference between the positive adjustments and the negative adjustments for any year is the "net positive adjustment" (if positive) or the "net negative adjustment" (if negative). The U.S. Holder will treat a "net positive adjustment" as additional interest income for the taxable year. For this purpose, the payments in a taxable year include the fair market value of property (including shares of our common stock) received in that year. A net negative adjustment will (1) reduce the U.S. Holder's interest income on the notes for that taxable year and (2) to the extent of any excess after the application of (1), give rise to an ordinary loss to the extent of the U.S. Holder's interest income on the notes during prior taxable years, reduced to any extent such interest was offset by prior net negative adjustments. Disposition or Conversion Generally, the sale, exchange or conversion of a note, or the redemption of a note for cash, will result in taxable gain or loss to a U.S. Holder. As described above, our calculation of the comparable yield and the schedule of projected payments for the notes takes into account the receipt of stock upon conversion and contingent additional principal as contingent payments with respect to the notes. Accordingly, we intend to treat the receipt of our common stock by a U.S. Holder upon the conversion of a note, as well as any contingent additional principal, as contingent payments under the CPDI regulations. Pursuant to our treatment of the notes as contingent payment debt instruments under the CPDI regulations as described above and the holders' agreement to be bound by our determination, gain or loss upon a sale, exchange, redemption or conversion of a note will generally be recognized as ordinary gain or loss, except that loss, if any, realized in excess of the amount of previously accrued original issue discount will be capital loss. Loss deductions are subject to limitations under the United States federal income tax laws. In the event of an exchange of notes for our common stock, upon conversion or otherwise, it is possible that a deduction for any such capital loss might be denied. Holders should consult their tax advisors regarding the deductibility of any such capital loss. The holder's realized gain or loss will be measured by the difference between the total value of the consideration received for the note (including the fair market value of our common stock) and the holder's tax basis in the note, as previously adjusted to reflect accrued original issue discount and the amounts of any projected payments. In general, a holder's tax basis in any common stock received in exchange for a note (including any fractional shares for which cash is received) will be the fair market value of the stock at the time of the exchange. While the matter is not entirely certain, the holding period for common stock received in the exchange may commence on the day following the date of the exchange. Holders should consult their tax advisors as to the application of the holding period rules to an exchange of a note for common stock. Constructive Dividend If at any time we make a distribution of property to our shareholders that would be taxable to the shareholders as a dividend for United States federal income tax purposes and, in accordance with the anti-dilution provisions of the notes, the conversion rate of the notes is increased or if the conversion rate is increased at our discretion, such increase may be deemed to be the payment of a taxable dividend to holders of the notes. For example, an increase in the conversion rate in the event of distributions of our evidences of indebtedness or our assets or in the event of an extraordinary cash dividend will generally result in deemed dividend treatment to holders of the notes, but generally an increase in the event of stock dividends or the distribution of rights to subscribe for common stock will not. However, there will be no deemed dividend treatment for regular cash dividends because there will be no adjustment therefor under the anti-dilution provisions of the notes. 29 Treatment of Non-U.S. Holders Payments of contingent interest made to Non-U.S. Holders will not be exempt from United States federal income or withholding tax and, therefore, Non-U.S. Holders will be subject to withholding on such payments of contingent interest at a rate of 30%, subject to reduction by an applicable treaty or upon the receipt of a Form W-8ECI from a Non-U.S. Holder claiming that the payments are effectively connected with the conduct of a United States trade or business. A Non-U.S. Holder that is subject to the withholding tax should consult its tax advisors as to whether it can obtain a refund for a portion of the withholding tax, either on the grounds that some portion of the contingent interest represents a return of principal under the CPDI regulations, or on some other grounds. All other payments on the notes made to a Non-U.S. Holder, including a payment in common stock pursuant to a conversion, and any gain realized on a sale or exchange of the notes (other than gain attributable to accrued contingent interest payments), will be exempt from United States federal income or withholding tax, as long as: o such Non-U.S. Holder does not own, actually or constructively, 10% or more of the total combined voting power of all classes of our stock entitled to vote and is not a controlled foreign corporation related, directly or indirectly, to us through stock ownership, o the statement requirement set forth in Section 871(b) or section 881(c) of the Code has been fulfilled with respect to the beneficial owner, as discussed below, o such payments and gain are not effectively connected with the conduct by such Non-U.S. Holder of a trade or business in the United States, and o our common stock continues to be actively traded within the meaning of section 871(h)(4)(C)(v)(I) of the Code (which, for these purposes and subject to certain exceptions, includes trading on the NYSE). The statement requirement referred to in the preceding paragraph will be fulfilled if the beneficial owner of a note certifies on IRS Form W-8BEN, under penalties of perjury, that it is not a United States person and provides its name and address. If a Non-U.S. Holder of notes is engaged in a trade or business in the United States, and if interest on the notes is effectively connected with the conduct of such trade or business, the Non-U.S. Holder, although exempt from the withholding tax discussed in the preceding paragraphs, will generally be subject to regular U.S. federal income tax on the interest and on any gain realized on the sale or exchange of the notes in the same manner as if it were a U.S. Holder. In lieu of the certificate described in the preceding paragraph, such a Non-U.S. Holder will be required to provide to the withholding agent a properly executed IRS Form W-8ECI (or successor form) in order to claim an exemption from withholding tax. In addition, if such a Non-U.S. Holder is a foreign corporation, such Holder may be subject to a branch profits tax equal to 30% (or such lower rate provided by an applicable treaty) of its effectively connected earnings and profits for the taxable year, subject to certain adjustments. Backup Withholding and Information Reporting Information reporting will apply to any payments (including a payment of shares of common stock pursuant to a conversion or of interest), we may make on, or the proceeds of the sale or other disposition or retirement of, the notes or dividends on shares of common stock with respect to certain noncorporate holders, and backup withholding (currently at a rate of 30%) may apply unless the recipient of such payment supplies a taxpayer identification number, certified under penalties of perjury, as well as certain other information, or otherwise establishes an exemption from backup withholding. Any amount withheld under the backup withholding rules will be allowable as a credit against the holder's federal income tax, if the required information is provided to the IRS. 30 SELLING SECURITYHOLDERS The notes were originally issued by us and sold to J.P. Morgan Securities Inc., Goldman, Sachs & Co. and Salomon Smith Barney Inc., to whom we refer to elsewhere as the "initial purchasers," in transactions exempt from the registration requirements of the federal securities laws. The initial purchasers resold the notes to persons reasonably believed by them to be "qualified institutional buyers" (as defined by Rule 144A under the Securities Act). The selling securityholders (which term includes their transferees, pledges, donees or successors) may from time to time offer and sell pursuant to this prospectus any and all of the notes and the shares of common stock issuable upon conversion and/or redemption of the notes. Set forth below are the names of each selling securityholder, the principal amount of the notes that may be offered by such selling securityholder pursuant to this prospectus and the number of shares of common stock into which such notes are convertible, each to the extent known to us as of the date of this prospectus. Unless set forth below, none of the selling securityholders has had a material relationship with us or any of our predecessors or affiliates within the past three years. Any or all of the notes or common stock listed below may be offered for sale pursuant to this prospectus by the selling securityholders from time to time. Accordingly, no estimate can be given as to the amounts of notes or common stock that will be held by the selling securityholders upon consummation of any such sales. In addition, the selling securityholders identified below may have sold, transferred, or otherwise disposed of all or a portion of their notes since the date on which the information regarding their notes was provided in transactions exempt from the registration requirements of the Securities Act.

However, this conversion rate will be subject to adjustment as described under "Description of the Notes -- Conversion Rights." As a result, the amount of common stock issuable upon conversion of the notes may increase or decrease in the future. (2) Information about other selling securityholders will be set forth in prospectus supplements, if required. (3) Assumes that any other holders of notes, or any future transferees, pledgees, donees or successors of or from any such other holders of notes, do not beneficially own any common stock other than the common stock issuable upon conversion of the notes at the initial conversion rate. The preceding table has been prepared based upon information furnished to us by the selling securityholders named in the table. From time to time, additional information concerning ownership of the notes and common stock may be known by certain holders thereof not named in the preceding table, with whom we believe we have no affiliation. Information about the selling securityholders may change over time. Any changed information will be set forth in prospectus supplements. PLAN OF DISTRIBUTION The notes and the common stock are being registered to permit public secondary trading of these securities by the holders thereof from time to time after the date of this prospectus. We have agreed, among other things, to bear all expenses (other than underwriting discounts and selling commissions) in connection with the registration and sale of the notes and the common stock covered by this prospectus. 31 We will not receive any of the proceeds from the offering of notes or the common stock by the selling securityholders. We have been advised by the selling securityholders that the selling securityholders may sell all or a portion of the notes and common stock beneficially owned by them and offered hereby from time to time on any exchange on which the securities are listed on terms to be determined at the times of such sales. The selling securityholders may also make private sales directly or through a broker or brokers. Alternatively, any of the selling securityholders may from time to time offer the notes or the common stock beneficially owned by them through underwriters, dealers or agents, who may receive compensation in the form of underwriting discounts, commissions or concessions from the selling securityholders and the purchasers of the notes and the common stock for whom they may act as agent. The aggregate proceeds to the selling securityholders from the sale of the notes or common stock offering will be the purchase price of such notes or common stock less discounts and commissions, if any. The notes and common stock may be sold from time to time in one or more transactions at fixed offering prices, which may be changed, or at varying prices determined at the time of sale or at negotiated prices. These prices will be determined by the holders of such securities or by agreement between these holders and underwriters or dealers who may receive fees or commissions in connection therewith. These transactions may include block transactions or crosses. Crosses are transactions in which the same broker acts as an agent on both sides of the trade. In connection with sales of the notes and the underlying common stock or otherwise, the selling securityholders may enter into hedging transactions with broker-dealers. These broker-dealers may in turn engage in short sales of the notes and the underlying common stock in the course of hedging their positions. The selling securityholders may also sell the notes and underlying common stock short and deliver notes and the underlying common stock to close out short positions, or loan or pledge notes and the underlying common stock to broker-dealers that in turn may sell the notes and the underlying common stock. To our knowledge, there are currently no plans, arrangements or understandings between any selling securityholders and any underwriter, broker-dealer or agent regarding the sale of the notes and the underlying common stock by the selling securityholders. Selling securityholders may not sell any or all of the notes and the underlying common stock offered by them pursuant to this prospectus. In addition, we cannot assure you that any such selling securityholder will not transfer, devise or gift the notes and the underlying common stock by other means not described in this prospectus. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 or Rule 144A of the Securities Act may be sold under Rule 144 or Rule 144A rather than pursuant to this prospectus. Our outstanding common stock is listed for trading on the New York Stock Exchange. The selling securityholders and any broker and any broker-dealers, agents or underwriters that participate with the selling securityholders in the distribution of the notes or the common stock may be deemed to be "underwriters" within the meaning of the Securities Act, in which event any commission received by such broker-dealers, agents or underwriters and any profit on the resale of the notes or the common stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. In addition, in connection with any resales of the notes, any broker-dealer who acquired the notes for its own account as a result of market-making activities or other trading activities must deliver a prospectus meeting the requirements of the Securities Act. Broker-dealers may fulfill their prospectus delivery requirements with respect to the notes (other than a resale of an unsold allotment from the original sale of the outstanding notes) with this prospectus. In addition, until , 2002 all securityholders effecting transactions in the notes may be required to deliver a prospectus and any and all supplements or amendments thereto. The notes were issued and sold on March 6, 2002 and March 19, 2002 in transactions exempt from the registration requirements of the federal securities laws to the initial purchasers. We have agreed to indemnify the initial purchasers and each selling securityholder, including each person, if any, who controls any of them within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each selling securityholder had agreed severally and not jointly, to indemnify us, the initial purchasers and each other selling shareholder, including each person, if any, who controls us or any of them within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act against certain liabilities arising under the Securities Act. 32 The selling securityholders and any other persons participating in the distribution will be subject to certain provisions under the federal securities laws, including Regulation M, which may limit the timing of purchases and sales of the notes and the underlying common stock by the selling securityholders and any other such person. In addition, Regulation M may restrict the ability of any person engaged in the distribution of the notes and the underlying common stock to engage in market-making activities with respect to the particular notes and the underlying common stock being distributed for a period of up to five business days prior to the commencement of such distribution. This may affect the marketability of the notes and the underlying common stock and the ability of any person or entity to engage in market-making activities with respect to the notes and the underlying common stock. We will use our reasonable best efforts to keep the registration statement of which this prospectus is a part effective until the earlier of (1) the sale pursuant to the registration statement of all the securities registered thereunder and (2) the expiration of the holding period applicable to such securities held by persons that are not our affiliates under Rule 144(k) under the Securities Act or any successor provision, subject to certain permitted exceptions in which case we may prohibit offers and sales of notes and common stock pursuant to the registration statement to which this prospectus relates. LEGAL MATTERS The validity of the notes and the shares of common stock issuable upon conversion of the notes has been passed upon for us by Jones, Day, Reavis & Pogue, New York, New York. EXPERTS The consolidated financial statements of Omnicom as of December 31, 2001 and 2000 and for each of the three years in the period ended December 31, 2001 and the related schedules included in Omnicom's Annual Report on Form 10-K for the fiscal year ended December 31, 2001, have been audited by Arthur Andersen LLP, independent public accountants, as indicated in their report with respect thereto, and are incorporated by reference in this prospectus in reliance upon the authority of said firm as experts in accounting and auditing. 33 PART II INFORMATION NOT REQUIRED IN PROSPECTUS Item 14. Other Expenses of Issuance and Distribution. Expenses payable in connection with the distribution of the securities being registered (estimated except for the registration fee), all of which will be borne by the registrant, are as follows: SEC Registration Fee ................................... $ 84,824 Legal Fees and Expenses ................................ $ 15,000 Miscellaneous Expenses ................................. $ 50,000 -------- Total ........................................ $149,824 ======== Item l5. Indemnification of Directors and Officers. Our certificate of incorporation contains a provision limiting the liability of 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, resulting in personal gain to which the director was not legally entitled or where such director's acts violated section 719 of the New York Business Corporation Law (approval of statutorily prohibited dividends, share repurchases or redemptions, distributions of assets on dissolution or loans to directors). Our 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 the consent in connection with any claim, action or proceeding to the fullest extent permitted by the New York Business Corporation Law. Section 722(a) of the New York Business Corporation Law provides that a corporation may indemnify any officer or director, made, or threatened to be made, a party to an action other than one by or in the right of the corporation, including an action by or in the right of any other corporation or other enterprise, that any director or officer of the corporation served in any capacity at the request of the corporation, because he was a director or officer of the corporation, or served such other corporation or other enterprise in any capacity, against judgments, fines, amounts paid in settlement and reasonable expenses, including attorneys' fees actually and necessarily incurred as a result of such action, or any appeal therein, if such director or officer acted, in good faith, for a purpose which he reasonably believed to be in, or in the case of service for any other corporation or other enterprise, not opposed to, the best interests of the corporation and, in criminal actions, in addition, had no reasonable cause to believe that his conduct was unlawful. Section 722(c) of the New York Business Corporation Law provides that a corporation may indemnify any officer or director made, or threatened to be made, a party to an action by or in the right of the corporation by reason of the fact that he is or was an officer or director of the corporation, or is or was serving at the request of the corporation as a director or officer of any other corporation, or other enterprise, 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, in the case of service for another corporation or other enterprise, not opposed to, the best interests of the corporation. The corporation may not, however, indemnify any officer or director pursuant to Section 722(c) in respect of (1) a threatened action, or a pending action that is settled or otherwise disposed of, or (2) any claim, issue or matter for which the person shall have been adjudged to be 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 the person is fairly and reasonably entitled to indemnity for that portion of the settlement and expenses as the court deems proper. Section 723 of the New York Business Corporation Law provides that an officer or director who has been successful on the merits or otherwise in the defense of a civil or criminal action of the character set forth in Section 722 is entitled to indemnification as permitted in such section. Section 724 of the New York Business Corporation Law permits a court to award the indemnification required by Section 722. We have entered into agreements with its directors to indemnify them for liabilities or costs arising out of any alleged or actual breach of duty, neglect, errors or omissions while serving as a director. We also maintain and pay premiums for directors' and officers' liability insurance policies. II-1 Item 16. Exhibits and Financial Statement Schedules.

Item 17. Undertakings. We undertake: (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 this registration statement (or the most recent post-effective amendment thereof) that, individually or in the aggregate, represent a fundamental change in the information in this 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 and of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and (iii) To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement. However, paragraphs (1)(i) and (1)(ii) shall not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by us pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in 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 the securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of post-effective amendment any of the securities being registered that remain unsold at the termination of the offering. We further undertake that, for purposes of determining any liability under the Securities Act of 1933, each filing of our annual report pursuant to Section 13(a) or 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 II-2 Exchange Act of 1934) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of the securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act, may be permitted to directors, officers or persons controlling us, pursuant to the provisions described under Item 15 above or otherwise, we have been advised that in the opinion of the Securities and Exchange Commission the 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 us 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.
