     Amortizable Bond Premium

     If a U.S. holder purchases a note for an amount (excluding any amounts attributable to pre-issuance accrued interest, as discussed above) in excess of the sum of all amounts payable on the note (other than in respect of stated interest), such excess will be considered “amortizable bond premium.”  For this purpose, in determining the sum of all amounts payable on the note, it will initially be assumed that we will exercise our rights to call the notes at a premium, and subsequent adjustments may be made if we do not in fact exercise our call rights.  This assumption may eliminate, reduce or defer any amortizable deductions.

Any of these activities may stabilize or maintain the market price of the notes above independent market levels. The underwriters are not required to engage in any of these activities, and may end any of them at any time.

     Expenses associated with this offering to be paid by us, other than the underwriting discount, are estimated to be $700,000.

     The notes offered hereby are further issuance of the existing notes and will become part of the same series as the existing notes. The notes will not be listed on any securities exchange or included in any authorized quotation system.

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

     In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

     J.P. Morgan Securities LLC, Citigroup Global Markets Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated are lead arrangers and book managers of the Omnicom Group credit facility. Affiliates of J.P. Morgan Securities LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated are syndication agents, affiliates of HSBC Securities (USA) Inc. and Wells Fargo Securities, LLC are documentation agents and an affiliate of Citigroup Global Markets Inc. is an administrative agent of the Omnicom Group credit facility. The other underwriters, or their affiliates, are also participants in the Omnicom Group credit facility.

     Deutsche Bank Trust Company Americas, an affiliate of Deutsche Bank Securities Inc., serves as trustee under the indenture governing the notes offered hereby as well as our outstanding Zero Coupon Zero Yield Convertible Notes due 2032, Zero Coupon Zero Yield Convertible Notes due 2033, Zero Coupon Zero Yield Convertible Notes due 2038, 5.90% Senior Notes due 2016, 6.250% Senior Notes due 2019, 4.45% Senior Notes due 2020 and 3.625% Senior Notes due 2022.

     All sales of notes in the United States will be made by or through U.S. registered broker-dealers as permitted by applicable regulations.

     SMBC Nikko Capital Markets Limited is not a U.S. registered broker-dealer and, therefore, intends to participate in the offering outside of the United States and, to the extent that the offering is within the United States, as facilitated by an affiliated U.S. registered broker-dealer, SMBC Nikko Securities America, Inc. (“SMBC Nikko-SI”), as permitted under applicable law. To that end, SMBC Nikko Capital Markets Limited and SMBC Nikko-SI have entered into an agreement pursuant to which SMBC Nikko-SI provides certain advisory and/or other services with respect to this offering. In return for the provision of such services by SMBC Nikko-SI, SMBC Nikko Capital Markets Limited will pay to SMBC Nikko-SI a mutually agreed-fee.

Special Note On Forward-Looking Statements

Certain of the statements in this prospectus constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. In addition, from time to time, we or our representatives have made or may make forward-looking statements, orally or in writing. These statements relate to future events or future financial performance and involve known and unknown risks and other factors that may cause our actual or our industry’s results, levels of activity or achievement to be materially different from those expressed or implied by any forward-looking statements. These risks and uncertainties, including those resulting from specific factors identified under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K, include, but are not limited to, our future financial position and results of operations, global economic conditions and conditions in the credit markets, losses on media purchases and production costs incurred on behalf of clients, reductions in client spending and/or a slowdown in client payments, competitive factors, changes in client communication requirements, managing conflicts of interest, the hiring and retention of personnel, maintaining a highly skilled workforce, our ability to attract new clients and retain existing clients, reliance on information technology systems, changes in government regulations impacting our advertising and marketing strategies, risks associated with assumptions we make in connection with our critical accounting estimates and legal proceedings, and our international operations, which are subject to the risks of currency fluctuations and foreign exchange controls. In some cases, forward-looking statements can be identified by terminology such as “may,” “will,” “could,” “would,” “should,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “predict,” “potential” or “continue” or the negative of those terms or other comparable terminology. These statements are our present expectations. Actual events or results may differ. We undertake no obligation to update or revise any forward-looking statement, except as required by law.

Use of Proceeds

Unless otherwise specified in an applicable prospectus supplement, Omnicom Group will use the proceeds it receives from the sale of the offered securities for general corporate purposes, which could include working capital, capital expenditures, acquisitions, refinancing of other debt or other capital transactions. Net proceeds may be temporarily invested prior to use. The precise amounts and timing of the application of proceeds will depend upon the funding requirements of Omnicom Group Inc. and its subsidiaries at the time of issuance and the availability of other funds.

Ratio of Earnings to Fixed Charges

The following table shows the ratio of earnings to fixed charges of Omnicom Group Inc. for each of the five most recent fiscal years.

Year Ended December 31,
2011	2010	2009	2008	2007
6.32x	6.12x	5.80x	6.70x	6.93x

 

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

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

Description Of Omnicom Group Inc. Common Stock

General

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

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

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

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

Description of Omnicom Group Inc. Preferred Stock

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

General

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

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

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

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

•

the title and stated value of the preferred stock;

•

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

•

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

•

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

•

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

•

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

•

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

•

voting rights, if any, of the preferred stock;

•

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

•

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

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

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

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

Rank

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

Dividends

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

Conversion and Exchange

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

Redemption

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

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

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

Liquidation Preference

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

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

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

Voting Rights

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

•

as otherwise stated in the prospectus supplement;

•

as otherwise stated in the certificate of designation establishing such series;

•

or as required by applicable law.

 

Description of Debt Securities

General

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

The debt securities offered by this prospectus will be joint and several unsecured obligations of Omnicom Group Inc., Omnicom Capital and/or Omnicom Finance and will be either senior or subordinated debt. We will issue the debt securities under an indenture between us and Deutsche Bank Trust Company Americas, or the Trustee. The indenture provides that our debt securities may be issued in one or more series, with different terms, in each case as authorized from time to time by us. The indenture also gives us the ability to reopen a previous issue of a series of debt securities and issue additional debt securities of that series or establish additional terms for that series of debt securities. The indenture does not limit the amount of debt securities or other unsecured debt which we may issue.

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

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

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

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

•

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

•

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

•

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

•

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

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

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

•

the title of the debt securities;

•

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

•

whether the debt securities will be senior or subordinated debt;

•

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

•

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

•

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

•

the maturity date or dates;

•

the interest rate;

•

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

•

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

•

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

•

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

•

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

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

Debt securities represented by a paper certificate may be presented for exchange or transfer at the office of the Registrar. Holders will not have to pay any service charge for any registration of transfer or exchange of their

certificates, but the Issuers may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with such registration of transfer.

Payment and Paying Agents

Distributions on the debt securities other than those represented by global notes will be made in the designated currency against surrender of the debt securities at the principal office of the paying agent. Payment will be made to the registered holder at the close of business on the record date for such payment. Interest payments will be made at the principal corporate trust office of the trustee in New York City, or by a check mailed to the holder at his registered address. Payments in any other manner will be specified in the prospectus supplement.

Book-Entry Procedures and Settlement

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

Optional Redemption

Unless an applicable prospectus supplement specifies otherwise, the debt securities will not be redeemable. In the event the debt securities are redeemable, the debt securities will be redeemable, as a whole or in part, at the Issuers’ option, at any time or from time to time, upon mailed notice to the registered address of each holder of debt securities at least 30 days but not more than 60 days prior to the redemption. The redemption price will be equal to the greater of (1) 100% of the principal amount of the debt securities to be redeemed and (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) on such debt securities discounted to the date of redemption, on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months), at a rate equal to the sum of the applicable Treasury Rate (as defined below) plus a make whole spread, which will be specified in the applicable prospectus supplement, plus accrued and unpaid interest thereon to the redemption date.

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

“Comparable Treasury Issue” means the United States Treasury security selected by the Reference Treasury Dealer (as defined below) as having a maturity comparable to the remaining term of the debt securities, that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the debt securities.

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

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

“Reference Treasury Dealer Quotations” means, with respect to the Reference Treasury Dealer and any redemption date, the average, as determined by the trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the trustee by the Reference Treasury Dealer at 3:30 p.m., New York City time, on the third business day preceding that redemption date.

“Remaining Scheduled Payments” means the remaining scheduled payments of principal of and interest on the debt securities that would be due after the related redemption date but for that redemption. If that redemption date is not an interest payment date with respect to the debt securities, the amount of the next succeeding scheduled interest payment on the debt securities will be reduced by the amount of interest accrued on the debt securities to such redemption date. On and after the redemption date, interest will cease to accrue on the debt securities or any portion of the debt securities called for redemption (unless we default in the payment of the redemption price and accrued interest). On or before the redemption date, we will deposit with a paying agent (or the trustee) money sufficient to pay the redemption price of and accrued interest on the debt securities to be redeemed on that date. If less than all of the debt securities are to be redeemed, the debt securities to be redeemed shall be selected by the trustee by a method the trustee deems to be fair and appropriate.

Consolidation, Merger or Sale

The Issuers may not consolidate with or merge into, or convey, transfer or lease their respective properties and assets as an entirety or substantially as an entirety to, any person, referred to as a “successor person,” except in the case of Omnicom Capital and Omnicom Finance with, into or to Omnicom Group Inc., each other or any other subsidiary of Omnicom Group Inc., unless:

•

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

•

the successor person expressly assumes the respective Issuer’s obligations with respect to the debt securities and the indenture;

•

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

•

the respective Issuer or the successor person has delivered to the trustee the certificates and opinions required under the indenture.

Modification of the Indenture

Under the indenture, the Issuers and the trustee may enter into supplemental indentures without obtaining the consent of any holder of debt securities:

•

to cure any ambiguity, defect or inconsistency;

•

to comply with the indenture’s provisions regarding successor corporations;

•

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

•

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

•

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

•

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

•

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

•

to establish additional series of debt securities as permitted by the indenture.

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

•

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

•

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

•

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

•

change the fixed maturity of any of the securities;

•

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

•

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

•

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

•

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

•

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

•

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

•

waive a redemption payment with respect to the securities.

Events of Default

The indenture provides that events of default regarding any series of debt securities will be:

•

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

•

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

•

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

•

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

•

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

•

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

•

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

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

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

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

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

Defeasance

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

•

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

•

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

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

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

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

Subordination

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

prospectus supplement relating thereto. To the extent we conduct operations through subsidiaries, the holders of debt securities (whether or not subordinated debt securities) will be structurally subordinated to the creditors of our subsidiaries except to the extent such subsidiary is a guarantor of such series of debt securities.

Further Issues

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

Concerning the Trustee

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

Applicable Law

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