THE INFORMATION IN THIS PROSPECTUS SUPPLEMENT AND THE RELATED PROSPECTUS MAY ONLY BE ACCURATE ON THE DATE OF THIS PROSPECTUS SUPPLEMENT. ------------------- As used in this prospectus supplement, 'Sirius,' 'company,' 'we,' 'our,' 'ours' and 'us' refer to Sirius Satellite Radio Inc., except where the context otherwise requires or as otherwise indicated. i SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS The following cautionary statements identify important factors that could cause our actual results to differ materially from those projected in the forward looking statements made in this prospectus supplement and the related prospectus. Any statements about our expectations, beliefs, plans, objectives, assumptions or future events or performance are not historical facts and may be forward looking. These statements are often, but not always, made through the use of words or phrases such as 'will likely result,' 'are expected to,' 'will continue,' 'is anticipated,' 'estimated,' 'intends,' 'plans,' 'projection' and 'outlook.' Accordingly, these statements involve estimates, assumptions and uncertainties which could cause actual results to differ materially from those expressed in them. Any forward-looking statements are qualified in their entirety by reference to the factors discussed throughout this prospectus supplement and the related prospectus. Among the significant factors that have a direct bearing on our results of operations are: if the offering of the notes is not completed, our need for substantial additional financing by early 2004, even following our recently completed recapitalization; our competitive position, as XM Satellite Radio, the other satellite radio service provider in the United States, began offering its service before us, has substantially more subscribers than us and may have certain competitive advantages; our dependence upon third parties to manufacture, distribute, market and sell SIRIUS radios and components for those radios; the unproven market for our service; and the useful life of our satellites, which have experienced circuit failures on their solar arrays and may not be covered by insurance. The circuit failures our satellites have experienced to date are not expected to limit the power of our broadcast signal, reduce the expected useful life of our satellites or otherwise affect our operations. These and other factors are discussed in 'Risk Factors' in the related prospectus and elsewhere in this prospectus supplement and in the documents incorporated herein by reference. Because the risk factors referred to above could cause actual results or outcomes to differ materially from those expressed in any forward-looking statements made by us or on our behalf, you should not place undue reliance on any of these forward-looking statements. Further, any forward-looking statement speaks only as of the date on which it is made, and we undertake no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for us to predict which will arise. In addition, we cannot assess with any precision the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. ii SUMMARY This summary highlights information contained elsewhere, or incorporated by reference, in this prospectus supplement and the related prospectus. Because it is a summary, it may not contain all of the information that is important to you. To understand this offering fully, you should read this entire prospectus supplement and the related prospectus carefully, including the financial statements and the documents incorporated by reference herein. ABOUT SIRIUS From our three orbiting satellites, we directly broadcast more than 100 channels, which we call 'streams,' of digital-quality audio throughout the continental United States for a monthly subscription fee of $12.95. We deliver 60 streams of 100% commercial-free music in virtually every genre, and over 40 streams of news, sports, weather, talk, comedy, public radio and children's programming. Our broad and deep range of music as well as our news, sports and entertainment programming is not available on conventional radio in any market in the United States. We hold one of only two licenses issued by the Federal Communications Commission to operate a national satellite radio system. On February 14, 2002, we launched our service in select markets and on July 1, 2002, we launched our service nationwide. Our primary source of revenues is subscription and activation fees. In addition, we derive revenues from selling limited advertising on our non-music streams. We have agreements with Ford Motor Company, DaimlerChrysler Corporation, BMW of North America, LLC, Nissan North America, Inc. and Volkswagen of America, Inc. that contemplate the manufacture and sale of vehicles that include SIRIUS radios. These alliances cover all major brands and affiliates of these automakers, including Ford, Lincoln, Mercury, Jaguar, Land Rover, Chrysler, Mercedes, BMW, MINI, Mazda, Dodge, Jeep, Volvo, Nissan, Infiniti, Volkswagen, Audi and Freightliner and Sterling heavy trucks. Ford, DaimlerChrysler, BMW, Nissan and Volkswagen are not required to manufacture or sell vehicles that include SIRIUS radios pursuant to these agreements. In the autosound aftermarket, SIRIUS radios are available for sale at various national and regional retailers, such as Best Buy, Circuit City, Ultimate Electronics, Tweeter Home Entertainment Group, Crutchfield and Good Guys. On December 31, 2002, SIRIUS radios were available at approximately 5,500 retail locations. On March 7, 2003, we completed a restructuring of our debt and equity capitalization. As part of this restructuring, we issued shares of our common stock in exchange for (i) 91% of our outstanding debt and (ii) all of our then outstanding convertible preferred stock. We also raised an additional $200 million in gross proceeds from the sale of our common stock for cash. Additional information regarding this restructuring is contained in our Annual Report on Form 10-K for the year ended December 31, 2002. Our principal executive offices are located at 1221 Avenue of the Americas, New York, New York 10020. Our telephone number is (212) 584-5100. Our internet address is sirius.com.

(footnotes continued on next page) S-3 (footnotes continued from previous page) (2) Operating expenses include non-cash stock compensation expense/(benefit) of $104, $1,206, $7,178, $14,044, $(7,867), $(9,024) and $559 for the years ended December 31, 1998, 1999, 2000, 2001 and 2002, and for the three months ended March 31, 2002 and 2003, respectively. (3) Included in the net loss of $48,396 for the year ended December 31, 1998 is $25,682 of special charges related primarily to the termination of launch and orbit related contracts required when we decided to enhance our satellite delivery system to include a third in-orbit satellite. (4) Included in the net income of $140,088 for the quarter ended March 31, 2003 is other income of $256,538 related to our debt restructuring. (5) The deemed dividend for the year ended December 31, 1998 relates primarily to the conversion feature associated with our 9.2% Series A Junior Cumulative Convertible Preferred Stock. We computed these deemed dividends in accordance with the SEC's position on accounting for preferred stock which is convertible at a discount to the market price. The deemed dividends for the years ended December 31, 1999 and 2000 relate primarily to the conversions of our 10 1/2% Series C Convertible Preferred Stock for shares of our common stock. The deemed dividend for the quarter ended March 31, 2003 relates primarily to the exchange of our preferred stock for shares of our common stock and warrants to purchase our common stock. (6) Marketable securities are stated at market and consist of fixed income securities with a maturity at the time of purchase of greater than three months. (7) Restricted investments are stated at amortized cost and include securities held by the trustee of our senior secured notes to pay interest in full on those notes through May 15, 2002 and certificates of deposit pledged to secure or reimbursement obligations under letters of credit required by lessors and other creditors. S-4 RISK FACTORS In addition to the other information in this prospectus supplement, in the related prospectus and incorporated by reference herein, the following risk factors should be considered carefully in evaluating us and our business and in deciding whether to invest in the notes. FUTURE SALES OF OUR COMMON STOCK MAY DEPRESS OUR STOCK PRICE. Sales of a substantial number of shares of our common stock in the public market or otherwise, by the company or a major stockholder, could depress the market price of the notes or our common stock, or both, and impair our ability to raise capital through the sale of additional equity securities. Other than certain executive officers, who have agreed not to sell shares of our common stock for 90 days following this offering except with the consent of Morgan Stanley & Co. Incorporated, none of our existing stockholders or directors have agreed to refrain from making sales of our common stock following this offering. WE MAY ISSUE ADDITIONAL EQUITY SECURITIES, WHICH WOULD LEAD TO DILUTION OF OUR ISSUED AND OUTSTANDING STOCK. The issuance of additional equity securities or securities convertible into equity securities would result in dilution of existing stockholders' equity interest in us. We are authorized to issue, without stockholder approval, 50,000,000 shares of preferred stock, $.001 par value per share, in one or more series, which may give other stockholders dividend, conversion, voting, and liquidation rights, among other rights, which may be superior to the rights of holders of our common stock. Our board of directors has no present intention of issuing any such preferred series, but reserves the right to do so in the future. In addition, we are authorized to issue, without stockholder approval, up to approximately 1,500,000,000 additional shares of common stock, $.001 par value per share. We are also authorized to issue, without stockholder approval, securities convertible into either common stock or preferred stock. THE MARKET PRICE OF THE NOTES COULD BE SIGNIFICANTLY AFFECTED BY THE MARKET PRICE OF OUR COMMON STOCK AND OTHER FACTORS. We expect that the market price of the notes will be significantly affected by the market price of our common stock. This may result in greater volatility in the market price of the notes than would be expected for nonconvertible debt securities. The market price of our common stock will likely continue to fluctuate in response to factors, including the factors discussed in the documents incorporated by reference, many of which are beyond our control. THE NOTES ARE NOT PROTECTED BY RESTRICTIVE COVENANTS. The indenture governing the notes does not contain any financial or operating covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by us or our subsidiary. The indenture contains no covenants or other provisions to afford protection to holders of the notes in the event of a fundamental change involving us except to the extent described under 'Description of Notes -- Repurchase at Option of the Holder.' The indenture contains no covenants or other provisions to afford protection to holders of the notes in the event our common stock is delisted by the Nasdaq National Market. WE MAY NOT HAVE THE ABILITY TO RAISE THE FUNDS NECESSARY TO PURCHASE THE NOTES UPON A FUNDAMENTAL CHANGE AS REQUIRED BY THE INDENTURE GOVERNING THE NOTES. Holders may require us to purchase their notes upon a fundamental change as described under 'Description of Notes -- Repurchase at Option of the Holder.' A fundamental change may also constitute an event of default, and result in the acceleration of the maturity of our then-existing indebtedness, under another indenture or other agreement. We cannot assure you that we would have sufficient financial resources, or would be able to arrange financing, to pay in cash the S-5 purchase price for the notes tendered by the holders. Failure by us to purchase the notes when required will result in an event of default with respect to the notes. WE CANNOT ASSURE YOU THAT AN ACTIVE TRADING MARKET WILL DEVELOP FOR THE NOTES. Prior to this offering there has been no trading market for the notes. We have been informed by the underwriters that they intend to make a market in the notes after the offering is completed. However, the underwriters may cease their market-making at any time. In addition, the liquidity of the trading market in the notes, and the market price quoted for the notes, may be adversely affected by changes in the overall market for this type of security and by changes in our financial performance or prospects or in the prospects for companies in our industry. In addition, such market-making activities will be subject to limits imposed by the Securities Act of 1933 and the Securities Exchange Act of 1934, and may be limited during the pendency of any shelf registration statement. As a result, we cannot assure you that an active trading market will develop for the notes. S-6 USE OF PROCEEDS We will receive net proceeds from the sale of the notes of approximately $168,875,000 ($194,206,250 if the underwriters exercise their option in full). We intend to use the net proceeds from the sale of the notes for general corporate purposes, including the marketing of our satellite radio service.

S-8 DESCRIPTION OF NOTES The notes are to be issued under an indenture dated as of May 23, 2003, as supplemented by a supplemental indenture dated as of May 23, 2003, between us and The Bank of New York, as trustee. A copy of the form of indenture will be made available to prospective investors in the notes upon request to us, and will be available for inspection during normal business hours at the corporate trust office of the trustee. The following summaries of certain provisions of the notes and the indenture do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the notes and the indenture, including the definitions therein of certain terms which are not otherwise defined in this prospectus supplement. Wherever particular provisions or defined terms of the indenture (or of the form of note which is a part thereof) are referred to, such provisions or defined terms are incorporated herein by reference. GENERAL The notes will be senior unsecured debt and will rank on a parity with all of our other existing and future senior unsecured debt and prior to all of our subordinated debt. The notes will be convertible into common stock as described under 'Conversion of Notes.' The notes will be limited to $175 million aggregate principal amount, or $201.25 million aggregate principal amount if the underwriters' option is fully exercised. The notes will be issued only in denominations of $1,000 and multiples of $1,000. The notes will mature on June 1, 2008 unless earlier converted or repurchased pursuant to a fundamental change. Neither we nor our subsidiary will be subject to any financial covenants under the indenture. In addition, neither we nor our subsidiary is restricted under the indenture from paying dividends, incurring debt, or issuing or repurchasing our securities. You are not afforded protection under the indenture in the event of a highly leveraged transaction or a change in control of us except to the extent described below under 'Repurchase at Option of the Holder.' We will pay interest on June 1 and December 1 of each year, beginning December 1, 2003, to record holders at the close of business on the preceding May 15 and November 15, as the case may be, except interest payable upon redemption or repurchase will be paid to the person to whom principal is payable, unless the redemption date or repurchase date, as the case may be, is an interest payment date. We will maintain an office in the Borough of Manhattan, The City of New York, for the payment of interest, which shall initially be an office or agency of the trustee. We may pay interest either: by check mailed to your address as it appears in the note register, provided that if you are a holder with an aggregate principal amount in excess of $2 million, you shall be paid, at your written election, by wire transfer in immediately available funds; or by transfer to an account maintained by you in the United States. However, payments to The Depository Trust Company, New York, New York, which we refer to as DTC, will be made by wire transfer of immediately available funds to the account of DTC or its nominee. Interest will be computed on the basis of a 360-day year composed of twelve 30-day months. CONVERSION OF NOTES You may convert any of your notes, in whole or in part, into common stock prior to the close of business on the final maturity date of the notes, subject to prior redemption or repurchase of the notes. The number of shares of common stock you will receive upon conversion of your notes will be determined by multiplying the number of $1,000 principal amount notes you convert by the S-9 conversion rate on the date of conversion. You may convert your notes in part so long as such part is $1,000 principal amount or an integral multiple of $1,000. If you have submitted your notes for repurchase upon a fundamental change, you may convert your notes only if you withdraw your repurchase election. Upon conversion of notes, a holder will not receive any cash payment of interest (unless such conversion occurs between a regular record date and the interest payment date to which it relates). Our delivery to the holder of the full number of shares of our common stock into which the note is convertible, together with any cash payment for such holder's fractional shares, or cash or a combination of cash and shares of our common stock in lieu thereof, will be deemed to satisfy our obligation to pay: the principal amount of the note; and accrued but unpaid interest attributable to the period from the most recent interest payment date to the conversion date. As a result, accrued but unpaid interest to the conversion date is deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the preceding paragraph, if notes are converted after a record date but prior to the next succeeding interest payment date, holders of such notes at the close of business on the record date will receive the interest payable on such notes on the corresponding interest payment date notwithstanding the conversion. Such notes, upon surrender for conversion, must be accompanied by funds equal to the amount of interest payable on the notes so converted; provided that no such payment need be made if (1) we have specified a purchase date following a fundamental change that is during such period or (2) only to the extent of overdue interest, any overdue interest exists at the time of conversion with respect to such note. The initial conversion rate for the notes is 724.6377 shares of common stock per $1,000 principal amount of notes, subject to adjustment as described below. We will not issue fractional shares of common stock upon conversion of notes. Instead, we will pay cash equal to the closing price of the common stock on the trading day prior to the conversion date. Except as described below, you will not receive any accrued interest or dividends upon conversion. To convert your note into common stock you must: complete and manually sign the conversion notice on the back of the note or facsimile of the conversion notice and deliver this notice to the conversion agent; surrender the note to the conversion agent; if required, furnish appropriate endorsements and transfer documents; if required, pay all transfer or similar taxes; and if required, pay funds equal to interest payable on the next interest payment date. The date you comply with these requirements is the conversion date under the indenture. We will adjust the conversion rate if any of the following events occurs: we issue common stock as a dividend or distribution on our common stock; we issue to all holders of common stock certain rights or warrants to purchase our common stock; we subdivide or combine our common stock; we distribute to all holders of our common stock, shares of our capital stock, evidences of indebtedness or assets, including securities but excluding: - rights or warrants specified above; - dividends or distributions specified above; and - cash distributions; if we distribute capital stock of, or similar equity interests in, a subsidiary or other business unit of ours, the conversion rate will be adjusted based on the market value of the S-10 securities so distributed relative to the market value of our common stock, in each case based on the average closing sales prices of those securities for the ten trading days commencing on and including the fifth trading day after the date on which 'ex-dividend trading' commences for such distribution on the NASDAQ National Market or such other national or regional exchange or market on which the securities are then listed or quoted; we distribute cash, excluding any dividend or distribution in connection with our liquidation, dissolution or winding up or any quarterly cash dividend on our common stock to the extent that the aggregate cash dividend per share of common stock in any quarter does not exceed 1.25% of the average of the last reported sale price of the common stock during the ten trading days immediately prior to the declaration date of the dividend; if an adjustment is required to be made under this clause as a result of a distribution that is a quarterly dividend, the adjustment would be based upon the amount by which the distribution exceeds the amount of the quarterly cash dividend permitted to be excluded pursuant to this clause. If an adjustment is required to be made under this clause as a result of a distribution that is not a quarterly dividend, the adjustment would be based upon the full amount of the distribution; we or our subsidiary makes a payment in respect of a tender offer or exchange offer for our common stock to the extent that the cash and value of any other consideration included in the payment per share of common stock exceeds the current market price per share of common stock on the trading day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer; and someone, other than us or our subsidiary, makes a payment in respect of a tender offer or exchange offer in which, as of the closing date of the offer, our board of directors is not recommending rejection of the offer. The adjustment referred to in this clause will only be made if: - the tender offer or exchange offer is for an amount that increases the offeror's ownership of common stock to more than 25% of the total shares of common stock outstanding; and - the cash and value of any other consideration included in the payment per share of common stock exceeds the current market price per share of common stock on the business day next succeeding the last date on which tenders or exchanges may be made pursuant to the tender or exchange offer; however, the adjustment referred to in this clause will generally not be made if as of the closing of the offer, the offering documents disclose a plan or an intention to cause us to engage in a consolidation or merger or a sale of all or substantially all of our assets. To the extent that we have a rights plan in effect upon conversion of the notes into common stock, you will receive, in addition to the common stock, the rights under the rights plan unless the rights have separated from the common stock at the time of conversion, in which case the conversion rate will be adjusted as if we distributed to all holders of our common stock, shares of our capital stock, evidences of indebtedness or assets as described above, subject to readjustment in the event of the expiration, termination or redemption of such rights. In the event of: any reclassification of our common stock; a consolidation, merger or combination involving us; or a sale or conveyance to another person or entity of all or substantially all of our property and assets; in which holders of our common stock would be entitled to receive stock, other securities, other property, assets or cash for their common stock, upon conversion of your notes you will be entitled to receive the same type of consideration which you would have been entitled to receive if you had converted the notes into our common stock immediately prior to any of these events. S-11 You may in certain situations be deemed to have received a distribution subject to United States federal income tax as a dividend in the event of any taxable distribution to holders of common stock or in certain other situations requiring a conversion rate adjustment. See 'Certain Federal Income Tax Considerations.' We may, from time to time, increase the conversion rate if our board of directors has made a determination that this increase would be in our best interests. Any such determination by our board will be conclusive. In addition, we may increase the conversion rate if our board of directors deems it advisable to avoid or diminish any income tax to holders of common stock resulting from any stock or rights distribution. See 'Certain Federal Income Tax Considerations.' We will not be required to make an adjustment in the conversion rate unless the adjustment would require a change of at least 1% in the conversion rate. However, we will carry forward any adjustments that are less than 1% of the conversion rate. Except as described above in this section, we will not adjust the conversion rate for any issuance of our common stock or convertible or exchangeable securities or rights to purchase our common stock or convertible or exchangeable securities. OPTIONAL REDEMPTION BY US We may not redeem the notes in whole or in part at our option prior to maturity. REPURCHASE AT OPTION OF THE HOLDER If a fundamental change of the company occurs at any time prior to the maturity of the notes you may require us to repurchase your notes, in whole or in part, on a date that is 30 days after the date of our notice of the fundamental change. The notes will be repurchased only in integral multiples of $1,000 principal amount. We will repurchase the notes at a price equal to 100% of the principal amount to be repurchased, plus accrued interest to, but excluding, the repurchase date. If the repurchase date is after a record date and prior to or on the related interest payment date, we will pay interest on the interest payment date to the record holder on the relevant record date. We will mail to all record holders a notice of a fundamental change within 10 days after it has occurred. We are also required to deliver to the trustee a copy of the fundamental change notice. If you elect to require us to repurchase your notes, you must deliver to us or our designated agent, on or before the 30th day after the date of our fundamental change notice, your repurchase notice and any notes to be repurchased, duly endorsed for transfer. We will promptly pay the repurchase price for notes surrendered for repurchase following the repurchase date. A 'fundamental change' is any transaction or event (whether by means of an exchange offer, liquidation, tender offer, consolidation, merger, combination, reclassification, recapitalization or otherwise) in connection with which all or substantially all of our common stock is exchanged for, converted into, acquired for or constitutes solely the right to receive, consideration which is not all or substantially all common stock that: is listed on, or immediately after the transaction or event will be listed on, a United States national securities exchange, or is approved, or immediately after the transaction or event will be approved, for quotation on the NASDAQ National Market or any similar United States system of automated dissemination of quotations of securities prices. We will comply with any applicable provisions of Rule 13e-4 and any other tender offer rules under the Exchange Act in the event of a fundamental change. These fundamental change repurchase rights could discourage a potential acquirer. However, this fundamental change repurchase feature is not the result of management's knowledge of any specific effort to obtain control of us by means of a merger, tender offer or solicitation, or part of a plan by management to adopt a series of anti-takeover provisions. The term 'fundamental S-12 change' is limited to specified transactions and may not include other events that might adversely affect our financial condition or business operations. Our obligation to offer to repurchase the notes upon a fundamental change would not necessarily afford you protection in the event of a highly leveraged transaction, reorganization, merger or similar transaction involving us. We may be unable to repurchase the notes in the event of a fundamental change. If a fundamental change were to occur, we may not have enough funds to pay the repurchase price for all tendered notes. Any future credit agreements or other agreements relating to our indebtedness may contain provisions prohibiting repurchase of the notes under certain circumstances, or expressly prohibit our repurchase of the notes upon a fundamental change or may provide that a fundamental change constitutes an event of default under that agreement. If a fundamental change occurs at a time when we are prohibited from repurchasing notes, we could seek the consent of our lenders to repurchase the notes or attempt to refinance this debt. If we do not obtain consent, we would not be permitted to repurchase the notes. Our failure to repurchase tendered notes would constitute an event of default under the indenture, which might constitute a default under the terms of our other indebtedness. MERGER AND SALE OF ASSETS BY US The indenture provides that we may not consolidate with or merge with or into any other person or convey, transfer or lease our properties and assets substantially as an entirety to another person, unless among other items: we are the surviving person, or the resulting, surviving or transferee person, if other than us is organized and existing under the laws of the United States, any state thereof or the District of Columbia; the successor person assumes all of our obligations under the notes and the indenture; and we or such successor person will not be in default under the indenture immediately after the transaction. When such a person assumes our obligations in such circumstances, subject to certain exceptions, we shall be discharged from all obligations under the notes and the indenture. EVENTS OF DEFAULT; NOTICE AND WAIVER The following will be events of default under the indenture: we fail to pay principal when due on the notes; we fail to pay any interest on the notes when due and such failure continues for a period of 30 days; we fail to perform or observe any of the covenants in the indenture for 60 days after notice; or certain events involving our bankruptcy, insolvency or reorganization. The trustee may withhold notice to the holders of the notes of any default, except defaults in payment of principal or interest on the notes. However, the trustee must consider it to be in the interest of the holders of the notes to withhold this notice. If an event of default occurs and continues, the trustee or the holders of at least 25% in principal amount of the outstanding notes may declare the principal and accrued interest on the outstanding notes to be immediately due and payable. In case of certain events of bankruptcy or insolvency involving us, the principal and accrued interest on the notes will automatically become due and payable. However, if we cure all defaults, except the nonpayment of principal or interest that became due as a result of the acceleration, and meet certain other conditions, with certain exceptions, this declaration may be cancelled and the holders of a majority of the principal amount of outstanding notes may waive these past defaults. S-13 Payments of principal or interest on the notes that are not made when due will accrue interest at the annual rate of 1% above the then applicable interest rate from the required payment date. The holders of a majority of outstanding notes will have the right to direct the time, method and place of any proceedings for any remedy available to the trustee, subject to limitations specified in the indenture. No holder of the notes may pursue any remedy under the indenture, except in the case of a default in the payment of principal or interest on the notes, unless: the holder has given the trustee written notice of an event of default; the holders of at least 25% in principal amount of outstanding notes make a written request, and offer reasonable indemnity, to the trustee to pursue the remedy; the trustee does not receive an inconsistent direction from the holders of a majority in principal amount of the notes; and the trustee fails to comply with the request within 60 days after receipt. MODIFICATION AND WAIVER The consent of the holders of a majority in principal amount of the outstanding notes is required to modify or amend the indenture. However, a modification or amendment requires the consent of the holder of each outstanding note affected if it would: extend the fixed maturity of such note; reduce the rate or extend the time for payment of interest of such note; reduce the principal amount of such note; reduce any amount payable upon repurchase of such note; change in any manner adverse to the holders our obligation to repurchase such note upon a fundamental change; impair the right of a holder to institute suit for payment on such note; change the currency in which any such note is payable; impair the right of a holder to convert such note; reduce the quorum or voting requirements under the indenture; change any obligation of ours to maintain an office or agency in the places and for the purposes specified in the indenture; subject to specified exceptions, modify certain of the provisions of the indenture relating to modification or waiver of provisions of the indenture; or reduce the percentage of notes required for consent to any modification of the indenture. We are permitted to modify certain provisions of the indenture without the consent of the holders of the notes. FORM, DENOMINATION AND REGISTRATION The notes will be issued: in fully registered form; without interest coupons; and in denominations of $1,000 principal amount and integral multiples of $1,000. The notes will be evidenced by one or more global notes. We will deposit the global note or notes with DTC and register the global notes in the name of Cede & Co. as DTC's nominee. Except as set forth below, a global note may be transferred, in whole or in part, only to another nominee of DTC or to a successor of DTC or its nominee. S-14 Holders may hold their interests in a global note directly through DTC if such holder is a participant in DTC, or indirectly through organizations that are participants in DTC (called 'participants'). Transfers between participants will be effected in the ordinary way in accordance with DTC rules and will be settled in clearing house funds. The laws of some states require that certain persons take physical delivery of securities in definitive form. As a result, the ability to transfer beneficial interests in the global note to such persons may be limited. Holders who are not participants may beneficially own interests in a global note held by DTC only through participants, or certain banks, brokers, dealers, trust companies and other parties that clear through or maintain a custodial relationship with a participant, either directly or indirectly (called 'indirect participants'). So long as Cede & Co., as the nominee of DTC, is the registered owner of a global note, Cede & Co. for all purposes will be considered the sole holder of such global note. Except as provided below, owners of beneficial interests in a global note will: not be entitled to have certificates registered in their names; not receive physical delivery of certificates in definitive registered form; and not be considered holders of the global note. We will pay interest on and the repurchase price of a global note to Cede & Co., as the registered owner of the global note, by wire transfer of immediately available funds on each interest payment date or the repurchase date, as the case may be. Neither we, the trustee nor any paying agent will be responsible or liable: for the records relating to, or payments made on account of, beneficial ownership interests in a global note; or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests. We have been informed that DTC's practice is to credit participants' accounts on that payment date with payments in amounts proportionate to their respective beneficial interests in the principal amount represented by a global note as shown in the records of DTC, unless DTC has reason to believe that it will not receive payment on that payment date. Payments by participants to owners of beneficial interests in the principal amount represented by a global note held through participants will be the responsibility of the participants, as is now the case with securities held for the accounts of customers registered in 'street name.' Because DTC can only act on behalf of participants, who in turn act on behalf of indirect participants, the ability of a person having a beneficial interest in the principal amount represented by the global note to pledge such interest to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of such interest, may be affected by the lack of a physical certificate evidencing its interest. Neither we, the trustee, registrar, paying agent nor conversion agent will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations. DTC has advised us that it will take any action permitted to be taken by a holder of notes, including the presentation of notes for exchange, only at the direction of one or more participants to whose account with DTC interests in the global note are credited, and only in respect of the principal amount of the notes represented by the global note as to which the participant or participants has or have given such direction. DTC has advised us that it is: a limited purpose trust company organized under the laws of the State of New York, and a member of the Federal Reserve System; a 'clearing corporation' within the meaning of the Uniform Commercial Code; and a 'clearing agency' registered pursuant to the provisions of Section 17A of the Exchange Act. S-15 DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes to the accounts of its participants. Participants include securities brokers, dealers, banks, trust companies and clearing corporations and other organizations. Some of the participants or their representatives, together with other entities, own DTC. Indirect access to the DTC system is 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. DTC has agreed to the foregoing procedures to facilitate transfers of interests in a global note among participants. However, DTC is under no obligation to perform or continue to perform these procedures, and may discontinue these procedures at any time. If DTC is at any time unwilling or unable to continue as depositary and a successor depositary is not appointed by us within 90 days, we will issue notes in certificated form in exchange for global notes. INFORMATION CONCERNING THE TRUSTEE We have appointed The Bank of New York, the trustee under the indenture, as paying agent, conversion agent, note registrar and custodian for the notes. The trustee or its affiliates provide banking and other services to us in the ordinary course of their business. The indenture contains certain limitations on the rights of the trustee, if it or any of its affiliates is then our creditor, to obtain payment of claims in certain cases or to realize on certain property received on any claim as security or otherwise. The trustee and its affiliates will be permitted to engage in other transactions with us. However, if the trustee or any affiliate continues to have any conflicting interest and a default occurs with respect to the notes, the trustee must eliminate such conflict or resign. S-16 CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS The following summary discusses the material U.S. federal income tax considerations relating to the purchase, ownership and disposition of the notes, and the conversion of the notes into shares of our common stock, by U.S. holders (as defined below). Except where noted, this summary deals only with notes held as capital assets and is applicable only to initial purchasers of notes who purchased the notes at their initial offering price. Additionally, this summary does not deal with special situations. For example, this summary does not address: tax consequences to holders who may be subject to special tax treatment, such as dealers in securities or currencies, financial institutions, real estate investment trusts, regulated investment companies, tax-exempt entities, traders in securities that elect to use a mark-to- market method of accounting for their securities holdings or insurance companies; tax consequences to persons holding notes as part of a hedging, integrated, constructive sale, or conversion transaction or a straddle; tax consequences to U.S. holders of notes whose 'functional currency' is not the U.S. dollar; alternative minimum tax consequences, if any; or any state, local or foreign tax consequences. The discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended (the 'Code'), and regulations, rulings and judicial decisions as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those discussed below. If a partnership holds our notes the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our notes, you should consult your tax advisor. IF YOU ARE CONSIDERING THE PURCHASE OF NOTES, YOU SHOULD CONSULT YOUR OWN TAX ADVISORS CONCERNING THE U.S. FEDERAL INCOME TAX CONSEQUENCES TO YOU AND ANY CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCAL, FOREIGN OR OTHER TAXING JURISDICTION. For purposes of this discussion, a 'U.S. holder' means a beneficial owner of a note that is for U.S. federal income tax purposes: a citizen or resident of the United States; a corporation or partnership created or organized in or under the laws of the United States or any political subdivision of the United States; an estate the income of which is subject to U.S. federal income taxation regardless of its source; or a trust if (1) it is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust, or (2) it has a valid election in effect under applicable U.S. Treasury regulations to be treated as a United States person. PAYMENTS OF INTEREST ON THE NOTES Stated interest on the notes will generally be taxable to you as ordinary income at the time it is paid or accrues in accordance with your method of accounting for tax purposes. CONSTRUCTIVE DISTRIBUTIONS The conversion rate of the notes will be adjusted in certain circumstances. Under Section 305(c) of the Code, adjustments (or failures to make adjustments) that have the effect of increasing your proportionate interest in our assets or earnings may in some circumstances result in a deemed distribution to you. Any deemed distributions will be taxable as a dividend, return of capital or capital gain in accordance with the earnings and profits rules under the Code. S-17 SALE, EXCHANGE, PURCHASE AND REDEMPTION OF NOTES Except as otherwise provided below under ' -- Conversion of Notes into Common Stock', you will generally recognize gain or loss upon the sale, exchange, purchase, redemption or other disposition of a note equal to the difference between the amount realized upon the sale, exchange, purchase, redemption or other disposition (less an amount equal to any accrued but unpaid interest not previously included in income, which will be taxable as interest income) and your adjusted tax basis in the note. Your adjusted tax basis in a note will generally be equal to the amount you paid for the note. Any gain or loss recognized on a disposition of the note will be capital gain or loss. If you are an individual and have held the note for more than one year, such capital gain will be subject to tax at a maximum rate of 20%. The deductibility of net capital losses by individuals and corporations is subject to limitations. CONVERSION OF NOTES INTO COMMON STOCK You will not recognize gain or loss on the conversion of your notes into common stock except to the extent of cash received in lieu of a fractional share of common stock. Cash received in lieu of a fractional share of common stock generally should be treated as a payment in exchange for such fractional share. The amount of gain or loss recognized on the deemed sale of such fractional share will be equal to the difference between the amount of cash you receive in respect of the fractional share, and the portion of your adjusted tax basis in the note that is allocable to the fractional share. The tax basis of the shares of common stock received upon a conversion will equal the adjusted tax basis of the note that was converted, reduced by the portion of adjusted tax basis allocated to any fractional share of common stock deemed exchanged for cash. Your holding period for shares of common stock will include the period during which you held the notes. You should contact your tax advisors concerning the ownership of common stock. INFORMATION REPORTING AND BACKUP WITHHOLDING In general, information reporting requirements will apply to payments of principal, premium, if any, and interest on a note, payments of actual or constructive dividends on common stock, and payment of the proceeds of the sale of a note or common stock to certain non-corporate, not otherwise exempt holders, and a 30% backup withholding tax may apply to such payments if the holder (i) fails to furnish or certify its correct taxpayer identification number to the payor in the manner required, (ii) is notified by the Internal Revenue Service that it has failed to report payments of interest and dividends properly, or (iii) under certain circumstances, fails to certify, under penalties of perjury, that it has not been notified by the Internal Revenue Service that it is subject to backup withholding for failure to report interest and dividend payments. Any amounts withheld under the backup withholding rules from a payment to a holder will be allowed as a credit against such holder's United States federal income tax liability and may entitle the holder to a refund. S-18 UNDERWRITING Under the terms and subject to the conditions contained in an underwriting agreement dated the date of this prospectus supplement, Morgan Stanley & Co. Incorporated and UBS Warburg LLC have severally agreed to purchase and we have agreed to sell to them, severally, $175 million principal amount of notes, as indicated below: AMOUNT NAME OF NOTES ---- -------- Morgan Stanley & Co. Incorporated........................... $140,000,000 UBS Warburg LLC............................................. 35,000,000 ------------ Total................................................... $175,000,000 ------------ ------------ The underwriting agreement provides that the obligations of the underwriters to pay for and accept delivery of the notes offered by this prospectus supplement and the accompanying prospectus are subject to the approval of certain legal matters by its counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the notes offered by this prospectus supplement and the accompanying prospectus if any notes are taken. However, the underwriters are not required to take or pay for any notes covered by the option of the underwriters to purchase additional notes as described below. The underwriters initially propose to offer part of the notes directly to the public at the public offering price listed on the cover page of this prospectus supplement and part to certain dealers at a price that represents a concession not in excess of $21.00 per note under the public offering price. After the notes are released to the public, the offering price and other selling terms may from time to time be varied by the underwriters. We have granted to the underwriters an option (exercisable for 30 days from the date of this prospectus supplement) to purchase, in the event the underwriters sell more than $175 million principal amount of notes, up to an additional $26.25 million aggregate principal amount of notes at the public offering price set forth on the cover page of this prospectus supplement, less underwriting discounts and commissions. The following table shows the total underwriting discounts and commissions to be paid to the underwriters by us for the notes. These amounts are shown assuming both no exercise and full exercise of the option of the underwriters to purchase up to $26.25 million additional principal amount of notes. UNDERWRITING DISCOUNTS AND COMMISSIONS PAID BY US NO EXERCISE FULL EXERCISE ------------------------------------------------- ----------- ------------- Per $1,000 principal amount of notes................ $ 35 $ 35 ---------- ---------- Total........................................... $6,125,000 $7,043,750 ---------- ---------- ---------- ---------- The notes are a new issue of securities with no established trading market. The underwriters have advised us that they presently intend to make a market in the notes as permitted by applicable laws and regulations. The underwriters are not obligated, however, to make a market in the notes and any such market-making activity may be discontinued at any time at the sole discretion of the underwriters. Accordingly, no assurance can be given as to the liquidity of, or trading markets for, the notes. We and certain of our executive officers have agreed, without the prior written consent of Morgan Stanley & Co. Incorporated, not to, during the period ending 90 days after the date of this prospectus supplement: offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for our common stock; or enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of our common stock; S-19 whether any transaction described above is to be settled by delivery of our common stock or such other securities, in cash or otherwise. The restrictions described in the preceding paragraph do not apply to: the issuance and sale of the notes offered by this prospectus supplement; the issuance of shares of common stock upon conversion of the notes; the issuance of our common stock upon the exercise of options, warrants or other rights exercisable for or the conversion of securities convertible into our common stock outstanding as of the date of this prospectus supplement of which Morgan Stanley & Co. Incorporated has been advised in writing; the issuance by us of additional options under our existing stock option plans, provided that such options are not exercisable during such 90-day period; transactions by any person other than us relating to shares of common stock or other securities acquired in open market transactions after the completion of the offering of the notes; and transfers by any person other than us as a bona fide gift, provided that the transferee agrees to be bound by such restrictions. In order to facilitate the offering of the notes, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the notes. Specifically, the underwriters may sell a greater principal amount of notes than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the principal amount of notes available for purchase by the underwriters under their option to purchase additional notes. An underwriter can close out a covered short sale by exercising its option to purchase additional notes or purchasing the notes in the open market. In determining the source of notes to close out a covered short sale, an underwriter will consider, among other things, the open market price of notes compared to the price available under the over-allotment option. The underwriters may also sell notes in excess of the over-allotment option, creating a naked short position. The underwriters must close out any naked short position by purchasing notes in the open market. A naked short position is more likely to be created if an underwriter is concerned that there may be downward pressure on the price of the notes in the open market after pricing that could adversely affect investors who purchase in the offering. As an additional means of facilitating the offering, the underwriters may bid for, and purchase, notes in the open market to stabilize the price of the notes. These activities may raise or maintain the market price of the notes above independent market levels or prevent or retard a decline in the market price of the notes. The underwriters are not required to engage in these activities, and may end any of these activities at any time. We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act. From time to time, Morgan Stanley & Co. Incorporated and UBS Warburg LLC have provided, and may provide, investment banking service to us. In addition, UBS Warburg LLC acted as our financial advisor in connection with our recent recapitalization, which was completed on March 7, 2003. LEGAL MATTERS The validity under state law of the notes offered hereby has been passed upon for us by Simpson Thacher & Bartlett, New York, New York. From time to time, Simpson Thacher & Bartlett represents The Blackstone Group L.P. on various matters in the regular course of business. Affiliates of Blackstone hold shares of our common stock. Certain partners of Simpson Thacher & Bartlett, members of their families, and related persons, have an indirect interest, through limited partnerships, in less than 1% of our common stock through a fund affiliated with Blackstone. Cravath, Swaine & Moore LLP, New York, New York, has represented the underwriters. S-20 PROSPECTUS $500,000,000 [SIRIUS LOGO] DEBT SECURITIES, PREFERRED STOCK, COMMON STOCK AND WARRANTS We from time to time may offer: secured or unsecured debt securities in one or more series; shares of preferred stock in one or more series; shares of common stock; warrants or other rights to purchase debt securities, preferred stock or common stock or any combination of securities; and any combination of debt securities, preferred stock, common stock or warrants, at an aggregate initial public offering price not to exceed $500,000,000.

THE INFORMATION IN THIS PROSPECTUS MAY ONLY BE ACCURATE ON THE DATE OF THIS PROSPECTUS. SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS The following cautionary statements identify important factors that could cause our actual results to differ materially from those projected in the forward-looking statements made in this prospectus. Any statements about our beliefs, plans, objectives, expectations, assumptions or future events or performance are not historical facts and may be forward-looking. These statements are often, but not always, made through the use of words or phrases such as 'will likely result,' 'are expected to,' 'will continue,' 'is anticipated,' 'estimated,' 'intends,' 'plans,' 'projection' and 'outlook.' Any forward-looking statements are qualified in their entirety by reference to the factors discussed throughout this prospectus, and particularly the risk factors described under 'Risk Factors' in this prospectus. Among the significant factors that could cause our actual results to differ materially from those expressed in the forward-looking statements are: our need for substantial additional financing by early 2004, even following our recently completed recapitalization; our competitive position, as XM Satellite Radio, the other satellite radio service provider in the United States, began offering its service before us, has substantially more subscribers than us and may have certain competitive advantages; our dependence upon third parties to manufacture, distribute, market and sell SIRIUS radios and components for those radios; the unproven market for our service; and the useful life of our satellites, which have experienced circuit failures on their solar arrays and may not be covered by insurance. The circuit failures our satellites have experienced to date are not expected to limit the power of our broadcast signal, reduce the expected useful life of our satellites or otherwise affect our operations. The risk factors referred to above could cause actual results or outcomes to differ materially from those expressed in any forward-looking statements made by us or on our behalf. Accordingly, you should not place undue reliance on any of these forward-looking statements. In addition, any forward-looking statement speaks only as of the date on which it is made, and we undertake no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which the statement is made, to reflect the occurrence of unanticipated events or otherwise. New factors emerge from time to time, and it is not possible for us to predict which will arise or to assess with any precision the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. 2 ABOUT THIS PROSPECTUS This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission using a 'shelf' registration process. Under this shelf process, we may sell any combination of the securities described in this prospectus in one or more offerings up to a total dollar amount of $500,000,000. This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus. You should read both this prospectus and any prospectus supplement together with the additional information described under the heading 'Where You May Find Additional Available Information About Us.' ABOUT SIRIUS From our three orbiting satellites, we directly broadcast more than 100 channels, which we call 'streams', of digital-quality audio throughout the continental United States for a monthly subscription fee of $12.95. We deliver 60 streams of 100% commercial-free music in virtually every genre, and over 40 streams of news, sports, weather, talk, comedy, public radio and children's programming. Our broad and deep range of music as well as our news, sports and entertainment programming is not available on conventional radio in any market in the United States. We hold one of only two licenses issued by the Federal Communications Commission to operate a national satellite radio system. On February 14, 2002, we launched our service in select markets and on July 1, 2002, we launched our service nationwide. Our primary source of revenues is subscription and activation fees. In addition, we derive revenues from selling limited advertising on our non-music streams. We have agreements with Ford Motor Company, DaimlerChrysler Corporation, BMW of North America, LLC, Nissan North America, Inc. and Volkswagen of America, Inc. that contemplate the manufacture and sale of vehicles that include SIRIUS radios. These alliances cover all major brands and affiliates of these automakers, including Ford, Lincoln, Mercury, Jaguar, Land Rover, Chrysler, Mercedes, BMW, MINI, Jaguar, Mazda, Dodge, Jeep, Volvo, Nissan, Infiniti, Volkswagen, Audi and Freightliner and Sterling heavy trucks. Ford, DaimlerChrysler, BMW, Nissan and Volkswagen are not required to manufacture or sell vehicles that include SIRIUS radios pursuant to these agreements. In the autosound aftermarket, SIRIUS radios are available for sale at various national and regional retailers, such as Best Buy, Circuit City, Ultimate Electronics, Tweeter Home Entertainment Group, Crutchfield and Good Guys. On December 31, 2002, SIRIUS radios were available at approximately 5,500 retail locations. On March 7, 2003, we completed a restructuring of our debt and equity capitalization. As part of this restructuring, we issued shares of our common stock in exchange (i) for 91% of our outstanding debt and (ii) all of our then outstanding convertible preferred stock. We also raised an additional $200 million in gross proceeds from the sale of our common stock for cash. Additional information regarding this restructuring is contained in our Annual Report on Form 10-K for the year ended December 31, 2002. Sirius Satellite Radio Inc. was incorporated in the State of Delaware as Satellite CD Radio, Inc. on May 17, 1990. On December 7, 1992, we changed our name to CD Radio Inc., and we formed a wholly owned subsidiary, Satellite CD Radio, Inc., that is the holder of our FCC license. On November 18, 1999, we changed our name again to Sirius Satellite Radio Inc. Our executive offices are located at 1221 Avenue of the Americas, New York, New York 10020, our telephone number is (212) 584-5100 and our internet address is sirius.com.

You should carefully consider the risk factors before investing in our securities. 4 RATIO OF EARNINGS TO COMBINED FIXED CHARGES AND PREFERRED STOCK DIVIDENDS The following table sets forth our ratio of earnings to combined fixed charges and preferred stock dividends for the periods indicated. FOR THE THREE MONTHS YEAR ENDED DECEMBER 31, ENDED ----------------------------------------------- MARCH 31, 1998 1999 2000 2001 2002 2003 ---- ---- ---- ---- ---- ---- Ratio of earnings to fixed charges(1)....................... -- -- -- -- -- 8.3(2) Ratio of earnings to combined fixed charges and preferred stock dividends(1)..................... -- -- -- -- -- 1.5(3) --------- (1) No figure is provided for any period during which the applicable ratio was less than 1.00. (2) Includes the effects of other income of $256.5 million associated with our debt restructuring. (3) Includes the effects of a $79.5 million deemed dividend associated with the exchange of our preferred stock for common stock and warrants. The ratio of earnings to fixed charges is computed by dividing our earnings, which include income before taxes (excluding the cumulative and transition effects of accounting changes) and fixed charges, by fixed charges. The ratio of earnings to combined fixed charges and preferred stock dividends is computed by dividing earnings by the sum of fixed charges and dividends on preferred stock. 'Fixed charges' consist of interest on debt and a portion of rentals determined to be representative of interest. For the years ended December 31, 1998, 1999, 2000, 2001 and 2002, our earnings were insufficient to cover our fixed charges by approximately $62.3 million, $119.4 million, $198.5 million, $255.0 million, and $420.8 million, respectively. Earnings were also inadequate to cover our combined fixed charges and preferred stock dividends over the same time periods by approximately $99.9 million, $153.5 million, $247.4 million, $297.2 million and $466.7 million, respectively. In connection with our recent restructuring, most of our debt and all of our outstanding preferred stock was retired and cancelled on March 7, 2003. USE OF PROCEEDS Unless otherwise indicated in the applicable prospectus supplement, we will use the net proceeds from the sale of the offered securities for general corporate purposes, including capital expenditures, the reduction of indebtedness and other purposes. We may invest funds not required immediately for such purposes in short-term obligations or we may use them to reduce the future level of our indebtedness. DESCRIPTION OF DEBT SECURITIES The following description of the terms of the debt securities sets forth certain general terms that may apply to the debt securities. The particular terms of any debt securities will be described in the prospectus supplement relating to those debt securities. For purposes of this 'Description of Debt Securities,' the term 'Sirius' refers to our company but not to any of its subsidiaries. Any senior debt securities will be issued in one or more series under an indenture, as supplemented or amended from time to time, between us and an institution that we will name in the related prospectus supplement, as trustee. Any subordinate debt securities will be issued in one or more series under an indenture, as supplemented or amended from time to time, between us and an institution that we will name in the related prospectus supplement, as trustee. For ease of reference, we will refer to the indenture relating to any senior debt securities as the senior indenture and to the indenture relating to any subordinate debt securities as the subordinate indenture. 5 This summary of the terms and provisions of the debt securities and the indentures is not necessarily complete, and we refer you to the copy of the forms of the indentures which are filed as exhibits to the registration statement of which this prospectus forms a part. Whenever we refer to particular defined terms of the indentures in this section or in a prospectus supplement, we are incorporating these definitions into this prospectus or the prospectus supplement. GENERAL The debt securities will be issuable in one or more series in accordance with an indenture supplemental to the applicable indenture or a resolution of our board of directors or a committee of the board. Unless otherwise specified in a prospectus supplement, each series of senior debt securities will rank equally in right of payment with all of our other senior obligations. Each series of subordinate debt securities will be subordinated and junior in right of payment to the extent and in the manner described in the subordinate indenture and any supplemental indenture relating to the subordinate debt securities. Except as otherwise provided in a prospectus supplement, the indentures do not limit our ability to incur other secured or unsecured debt, whether under the indentures, any other indenture that we may enter into in the future or otherwise. For more information, you should read the prospectus supplement relating to a particular offering of securities. The applicable prospectus supplement will describe the following terms of the series of debt securities with respect to which this prospectus is being delivered: the title of the debt securities of the series and whether such series constitutes senior debt securities or subordinated debt securities; any limit on the aggregate principal amount of the debt securities; the person to whom any interest on a debt security shall be payable, if other than the person in whose name that debt security is registered on the regular record date;

6 the denominations in which any debt securities will be issuable, if other than denominations of $1,000 and any integral multiple thereof; the currency, currencies or currency units in which payment of principal of and any premium and interest on debt securities of the series shall be payable, if other than United States dollars; any index, formula or other method used to determine the amount of payments of principal of and any premium and interest on the debt securities; if the principal amount payable at the stated maturity of debt securities of the series will not be determinable as of any one or more dates before the stated maturity, the amount that will be deemed to be the principal amount as of any date for any purpose, including the principal amount thereof which will be due and payable upon any maturity other than the stated maturity or which will be deemed to be outstanding as of any date (or, in any such case, the manner in which the deemed principal amount is to be determined), and if necessary, the manner of determining the equivalent thereof in United States currency; if the principal of or any premium or interest on any debt securities is to be payable, at our election or the election of the holders, in one or more currencies or currency units other than that or those in which such debt securities are stated to be payable, the currency, currencies or currency units in which payment of the principal of and any premium and interest on such debt securities shall be payable, and the periods within which and the terms and conditions upon which such election is to be made; if other than the principal amount thereof, the portion of the principal amount of the debt securities which will be payable upon declaration of the acceleration of the maturity thereof or provable in bankruptcy;

and any other terms of the debt securities not inconsistent with the provisions of the applicable indenture. We may sell debt securities at a substantial discount below their stated principal amount or debt securities that bear no interest or bear interest at a rate which at the time of issuance is below market rates. We will describe the material United States federal income tax consequences, accounting and other special considerations applicable to the debt securities in the applicable prospectus supplement. If the purchase price of any of the debt securities is payable in one or more foreign currencies or currency units or if any debt securities are denominated in one or more foreign currencies or currency units or if the principal of, premium, if any, or interest, if any, on any debt securities is payable in one or more foreign currencies or currency units, we will set forth the restrictions, elections, specific terms and other information with respect to such issue of debt securities and such foreign currency or currency units in the applicable prospectus supplement. EXCHANGE, REGISTRATION, TRANSFER AND PAYMENT Unless otherwise indicated in the applicable prospectus supplement, principal, premium, if any, and interest, if any, on the debt securities will be payable, without coupons, and the exchange of and the transfer of debt securities will be registrable, at our office or agency maintained for such purpose in the Borough of Manhattan, The City of New York and at any other office or agency maintained for such purpose. Unless otherwise indicated in the applicable prospectus supplement, the debt securities will be issued in denominations of $1,000 and any integral multiples thereof. Holders may present each series of debt securities for exchange as provided above, and for registration of transfer, with the form of transfer endorsed thereon, or with a satisfactory written instrument of transfer, duly executed, at the office of the appropriate securities registrar or at the office of any transfer agent designated by us for such purpose and referred to in the applicable prospectus supplement, without service charge and upon payment of any taxes and other governmental charges as described in the indenture. We will appoint the trustee of each series of debt securities as securities registrar for such series under the indenture. If the applicable prospectus supplement refers to any transfer agents, in addition to the securities registrar initially designated by us with respect to any series, we may at any time rescind the designation of any such transfer agent or approve a change in the location through which any such transfer agent acts, provided that we maintain a transfer agent in each place of payment for the series. We may at any time designate additional transfer agents with respect to any series of debt securities. All moneys paid by us to a paying agent for the payment of principal, premium, if any, or interest, if any, on any debt security which remain unclaimed for two years after such principal, premium or interest has become due and payable may be repaid to us, and after such time, the holder of such debt security may look only to us for payment. In the event of any redemption, we shall not be required to (a) issue, register the transfer of or exchange debt securities of any series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of debt securities of that series to be redeemed and ending at the close of business on the day of such mailing or (b) register the transfer of or exchange any debt security called for redemption, except, in the case of any debt securities being redeemed in part, any portion not being redeemed. BOOK-ENTRY SYSTEM The provisions set forth below in this section headed 'Book-Entry System' will apply to the debt securities of any series if the prospectus supplement relating to such series so indicates. 8 Unless otherwise indicated in the applicable prospectus supplement, the debt securities of such series will be represented by one or more global securities registered with a depositary named in the prospectus supplement relating to such series. Except as set forth below, a global security may be transferred, in whole but not in part, only to the depositary or another nominee of the depositary. The specific terms of the depositary arrangement with respect to a series of debt securities will be described in the prospectus supplement relating to the series. We anticipate that the following provisions will generally apply to depositary arrangements. Upon the issuance of a global security, the depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of the debt securities represented by such global security to the accounts of institutions or persons, commonly known as participants, that have accounts with the depositary or its nominee. The accounts to be credited will be designated by the underwriters, dealers or agents. Ownership of beneficial interests in a global security will be limited to participants or persons that may hold interests through participants. Ownership of interests in such global security will be shown on, and the transfer of those ownership interests will be effected only through, records maintained by the depositary (with respect to participants' interests) and such participants (with respect to the owners of beneficial interests in such global security). The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of the securities in definitive form. These limits and laws may impair the ability to transfer beneficial interests in a global security. So long as the depositary, or its nominee, is the registered holder and owner of such global security, the depositary or such nominee, as the case may be, will be considered the sole owner and holder for all purposes of the debt securities and for all purposes under the applicable indenture. Except as set forth below or as otherwise provided in the applicable prospectus supplement, owners of beneficial interests in a global security will not be entitled to have the debt securities represented by such global security registered in their names, will not receive or be entitled to receive physical delivery of debt securities in definitive form and will not be considered to be the owners or holders of any debt securities under the applicable indenture or such global security. Accordingly, each person owning a beneficial interest in a global security must rely on the procedures of the depositary and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder of debt securities under the applicable indenture of such global security. We understand that under existing industry practice, in the event we request any action of holders of debt securities or if an owner of a beneficial interest in a global security desires to take any action that the depositary, as the holder of such global security is entitled to take, the depositary would authorize the participants to take such action, and that the participants would authorize beneficial owners owning through such participants to take such actions or would otherwise act upon the instructions of beneficial owners owning through them. Payments of principal of and premium, if any, and interest, if any, on debt securities represented by a global security will be made to the depositary or its nominee, as the case may be, as the registered owner and holder of such global security, against surrender of the debt securities at the principal corporate trust office of the trustee. Interest payments will be made at the principal corporate trust office of the trustee or by a check mailed to the holder at its registered address. Payment in any other manner will be specified in the prospectus supplement. We expect that the depositary, upon receipt of any payment of principal, premium, if any, of interest, if any, in respect of a global security, will credit immediately participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such global security as shown on the records of the depositary. We expect that payments by participants to owners of beneficial interests in a global security held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in 'street name,' and will be the responsibility of such participant. Neither Sirius nor the trustee nor any agent of Sirius or the trustee will have any responsibility or liability for any aspect of the records relating to, or 9 payments made on account of, beneficial ownership interests in a global security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between the depositary and its participants or the relationship between such participants and the owners of beneficial interests in such global security owning through such participants. Unless and until it is exchanged in whole or in part for debt securities in definitive form, a global security may not be transferred except as a whole by the depositary to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary. Unless otherwise provided in the applicable prospectus supplement, debt securities represented by a global security will be exchangeable for debt securities in definitive form of like tenor as such global security in denominations of $1,000 and in any greater amount that is an integral multiple thereof if: the depositary notifies us and the trustee that it is unwilling or unable to continue as depositary for such global security or if at any time the depositary ceases to be a clearing agency registered under the Exchange Act and a successor depositary is not appointed by us within 90 days; we, in our sole discretion, determine not to have all of the debt securities represented by a global security and notify the trustee thereof; or there shall have occurred and be continuing an event of default or an event which, with the giving of notice or lapse of time, or both, would constitute an event of default with respect to the debt securities. Any debt security that is exchangeable pursuant to the preceding sentence is exchangeable for debt securities registered in such names as the depositary shall instruct the trustee. It is expected that such instructions may be based upon directions received by the depositary from its participants with respect to ownership of beneficial interests in such global security. Subject to the foregoing, a global security is not exchangeable except for a global security or global securities of the same aggregate denominations to be registered in the name of the depositary or its nominee. OPTION TO DEFER INTEREST PAYMENTS OR TO PAY-IN-KIND If so described in the applicable prospectus supplement, we will have the right, at any time and from time to time during the term of any series of debt securities, to defer the payment of interest for such number of consecutive interest payment periods as may be specified in the applicable prospectus supplement, subject to the terms, conditions and covenants, if any, specified in such prospectus supplement, provided that an extension period may not extend beyond the stated maturity of the final installment of principal of the series of debt securities. If provided in the applicable prospectus supplement, we will have the right, at any time and from time to time during the term of any series of debt securities, to make payments of interest by delivering additional debt securities of the same series. COVENANTS The covenants, if any, that will apply to a particular series of debt securities will be set forth in the indenture relating to such series of debt securities. Except as otherwise specified in the applicable prospectus supplement with respect to any series of debt securities, we may remove or add covenants without the consent of holders of the securities. DEFEASANCE AND COVENANT DEFEASANCE We may be discharged from our obligations on the debt securities of any series that have matured or will mature or be redeemed within one year if we deposit with the trustee enough cash to pay all the principal, interest and any premium due to the stated maturity date or 10 redemption date of the debt securities and comply with certain other conditions set forth in the applicable indenture. Each indenture contains a provision that permits us to elect either: to be discharged after 90 days from all of our obligations (subject to limited exceptions) with respect to any series of debt securities then outstanding ('defeasance'); and/or to be released from our obligations under certain covenants and from the consequences of an event of default resulting from a breach of those covenants or cross-default ('covenant defeasance'). To make either of the above elections, we must deposit in trust with the trustee money and/or U.S. Government Obligations, if the debt securities are denominated in U.S. dollars, and/or Foreign Government Securities, if the debt securities are denominated in a foreign currency, which through the payment of principal and interest under their terms will provide sufficient money, without reinvestment, to repay in full those senior or subordinate debt securities. As a condition to defeasance or covenant defeasance, we must deliver to the trustee an opinion of counsel that the holders of the debt securities will not recognize income, gain or loss for federal income tax purposes as a result of the defeasance. If either of the above events occur, the holders of the debt securities of the series will not be entitled to the benefits of the indenture, except for registration of transfer and exchange of debt securities and replacement of lost, stolen or mutilated debt securities. EVENTS OF DEFAULT The following events are defined in the indentures as 'Events of Default' with respect to a series of debt securities (unless such event is specifically inapplicable to a particular series as described in the applicable prospectus supplement): failure to pay any interest on any debt security of that series when due, which failure continues for 30 days; failure to pay principal of or any premium on any debt security of that series when due; failure to deposit any sinking fund payment, within 30 days of when due, in respect of any debt security of that series; with respect to each series of debt securities, failure to perform any other of our covenants applicable to that series, which failure continues for 90 days after written notice to us by the trustee or to us and the trustee by the holders of at least 25% in principal amount of the outstanding debt securities of that series specifying such failure, requiring it to be remedied and stating that such notice is a 'Notice of Default'; certain events of bankruptcy, insolvency or reorganization involving us; and any other Event of Default provided with respect to debt securities of that series. If an Event of Default for any series of debt securities occurs and continues, the trustee or holders of at least 25% in principal amount of the debt securities of that series may declare the entire principal amount of all the debt securities of that series to be due and payable immediately. Subject to certain conditions, the declaration may be annulled and past defaults (except uncured payment defaults and certain other specified defaults) may be waived by the holders of a majority of the principal amount of the outstanding debt securities of that series. An Event of Default for a particular series of debt securities does not necessarily constitute an event of default for any other series of debt securities issued under an indenture. Each indenture will require the trustee, within 90 days after the occurrence of a default known to it with respect to any outstanding series of debt securities, to give the holders of that series notice of the default if uncured or not waived. However, the trustee may withhold this notice if it determines in good faith that the withholding of this notice is in the interest of those holders, except that the trustee may not withhold this notice in the case of a payment default. The 11 term 'default' for the purpose of this provision means any event that is, or after notice or lapse of time or both would become, an Event of Default with respect to debt securities of that series. Other than the duty to act with the required standard of care during an Event of Default, a trustee is not obligated to exercise any of its rights or powers under the applicable indenture at the request or direction of any of the holders of debt securities, unless the holders have offered to the trustee reasonable indemnification. Each indenture provides that the holders of a majority in principal amount of outstanding debt securities of any series may in certain circumstances direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or other power conferred on the trustee. The senior indenture will include a covenant that we will file annually with the trustee a certificate of no default, or specifying any default that exists. MODIFICATION, WAIVER AND MEETINGS We and the trustee may enter into supplemental indentures without the consent of the holders of debt securities for one or more of the following purposes: to evidence the succession of another person to us pursuant to the provisions of the applicable indenture relating to consolidations, mergers and sales of assets and the assumption by the successor of our covenants, agreements and obligations in the applicable indenture and in the debt securities; to surrender any right or power conferred upon us by the applicable indenture, to add to our covenants such further covenants, restrictions, conditions or provisions for the protection of the holders of all or any series of debt securities as our board of directors shall consider to be for the protection of the holders of the debt securities, and to make the occurrence, or the occurrence and continuance, of a default in any of the additional covenants, restrictions, conditions or provisions a default or an Event of Default under the applicable indenture (provided, however, that with respect to any such additional covenant, restriction, condition or provision, the supplemental indenture may provide for a period of grace after default, which may be shorter or longer than that allowed in the case of other defaults, may provide for an immediate enforcement upon the default, may limit the remedies available to the trustee upon the default, or may limit the right of holders of a majority in aggregate principal amount of any or all series of debt securities to waive the default); to cure any ambiguity or omission or to correct or supplement any provision contained in the applicable indenture, in any supplemental indenture or in any debt securities that may be defective or inconsistent with any other provision contained therein, to convey, transfer, assign, mortgage or pledge any property to or with the trustee, or to make such other provisions in regard to matters or questions arising under the applicable indenture, in each case as shall not adversely affect the interests of any holders of debt securities of any series in any material respect; to modify or amend the applicable indenture to permit the qualification of such indenture or any supplemental indenture under the Trust Indenture Act as then in effect; to add guarantees with respect to any or all of the debt securities or to secure any or all of the debt securities; to add to, change or eliminate any of the provisions of the applicable indenture with respect to one or more series of debt securities; so long as any such addition, change or elimination not otherwise permitted under the applicable indenture shall (1) neither apply to any debt security of any series created before the execution of the supplemental indenture and entitled to the benefit of the provision nor modify the rights of the holders of any debt security with respect to the provision, or (2) become effective only when there is no such debt security outstanding; to evidence and provide for the acceptance of appointment by a successor or separate trustee with respect to the debt securities of one or more series and to add to or change 12 any of the provisions of the applicable indenture as shall be necessary to provide for or facilitate the administration of such indenture by more than one trustee; to establish the form or terms of debt securities of any series; to provide for uncertificated debt securities in addition to or in place of certificated debt securities (provided that the uncertificated debt securities are issued in registered form for purposes of Section 163(f) of the Internal Revenue Code or in a manner such that the uncertificated debt securities are described in Section 163(f)(2)(B) of such Code); and to make any change that does not adversely affect the rights of any holder. Modifications and amendments of the applicable indenture may be made by us and the trustee with the consent of the holders of a majority in principal amount of the outstanding debt securities of each series affected by such modification or amendment; provided, however, that no such modification or amendment may, without the consent of the holder of each outstanding debt security affected thereby: change the stated maturity of the principal of, or any installment of principal of or interest on, any debt security; reduce the principal amount of, rate of interest on or any premium payable upon the redemption of any debt security; reduce the amount of principal of an original issue discount security payable upon acceleration of the maturity thereof; change the place of payment where, or the coin or currency in which, any debt security or any premium or interest thereon is payable; impair the right to institute suit for the enforcement of any payment on or with respect to any debt security after the stated maturity, redemption date or repayment date; reduce the percentage in principal amount of outstanding debt securities of any series, the consent of whose holders is required for modification or amendment of the applicable indenture or for waiver of compliance with certain provisions of such indenture or for waiver of certain defaults; change the optional redemption or repurchase provisions in a manner adverse to any holder; or modify any of the provisions set forth in this paragraph, except to increase the percentage of holders whose consent is required for modifications and amendments of the applicable indenture or to provide that certain other provisions of the applicable indenture may not be modified or waived without the consent of the holder of each outstanding debt security affected thereby. The holders of a majority in principal amount of the outstanding debt securities of each series may, on behalf of the holders of all the debt securities of that series, waive, insofar as that series is concerned, compliance by us with certain restrictive provisions of the applicable indenture. The holders of a majority in principal amount of the outstanding debt securities of each series may, on behalf of all holders of debt securities of that series and any coupons relating to such series, waive any past default under the applicable indenture with respect to debt securities of the series, except a default (a) in the payment of principal of or any premium or interest on any debt security of such series or (b) in respect of a covenant or provision of the applicable indenture which cannot be modified or amended without the consent of each holder of outstanding debt securities of the affected series. The indentures provide that in determining whether the holders of the requisite principal amount of the outstanding debt securities have given any request, demand, authorization, direction, 13 notice, consent or waiver thereunder or whether a quorum is present at a meeting of holders of debt securities: the principal amount of an original issue discount security that shall be deemed to be outstanding shall be the amount of the principal thereof that would be due and payable as of the date of such determination upon acceleration of the maturity thereof; the principal amount of a debt security denominated in other than U.S. dollars shall be the U.S. dollar equivalent, determined on the date of original issuance of such debt security, of the principal amount of such debt security (or, in the case of an original issue discount security, the U.S. dollar equivalent on the date of original issuance of such debt security of the amount determined (as provided above) of such debt security); and debt securities owned by us or any subsidiary of ours shall be disregarded and deemed not to be outstanding. In addition, we and the trustees may execute, without the consent of any holder of the debt securities, any supplemental indenture for the purpose of creating any new series of debt securities. SUBORDINATION Except as set forth in the applicable prospectus supplement, the subordinate indenture provides that the subordinate debt securities are subordinate and junior in right of payment to all of our senior indebtedness. If an Event of Default occurs with respect to any senior indebtedness permitting the holders thereof to accelerate the maturity thereof and the default is the subject of judicial proceedings or written notice of such Event of Default, requesting that payments on subordinate debt securities cease, is given to us by the holders of senior indebtedness, then unless and until (1) the default in payment or Event of Default shall have been cured or waived or (2) 120 days shall have passed after written notice is given and the default is not the subject of judicial proceedings, no direct or indirect payment, in cash, property or securities, by set-off or otherwise, will be made or agreed to be made on account of the subordinate debt securities or interest thereon or in respect of any repayment, redemption, retirement, purchase or other acquisition of subordinate debt securities. Except as set forth in the applicable prospectus supplement, the subordinate indenture provides that in the event of: any insolvency, bankruptcy, receivership, reorganization or other similar proceeding relating to us, our creditors or our property; or any proceeding for the liquidation or dissolution of Sirius, all present and future senior indebtedness, including interest accruing after the commencement of the proceeding, will first be paid in full before any payment or distribution, whether in cash, securities or other property, will be made by us on account of subordinate debt securities. In that event, any payment or distribution, whether in cash, securities or other property, other than securities of Sirius or any other corporation provided for by a plan of reorganization or a readjustment, the payment of which is subordinate, at least to the extent provided in the subordination provisions of the indenture, to the payment of all senior indebtedness at the time outstanding and to any securities issued in respect thereof under any such plan of reorganization or readjustment and other than payments made from any trust described in the 'Defeasance and Covenant Defeasance' above, which would otherwise but for the subordination provisions be payable or deliverable in respect of subordinate debt securities, including any such payment or distribution which may be payable or deliverable by reason of the payment of any other indebtedness of ours being subordinate to the payment of subordinated debt securities, will be paid or delivered directly to the holders of senior indebtedness or to their representative or trustee, in accordance with the priorities then existing among such holders, until all senior indebtedness shall have been paid in full. No present or future holder of any senior indebtedness will be prejudiced in the right to enforce subordination of the indebtedness evidenced by subordinate debt securities by any act or failure to act on our part. 14 The term 'Senior Indebtedness' means: (1) the principal, premium, if any, interest and all other amounts owed in respect of all our (A) indebtedness for money borrowed and (B) indebtedness evidenced by securities, debentures, bonds or other similar instruments; (2) all our capital lease obligations; (3) all our obligations issued or assumed as the deferred purchase price of property, all our conditional sale obligations and all our obligations under any title retention agreement (but excluding trade accounts payable arising in the ordinary course of business); (4) all our obligations for the reimbursement of any letter of credit, banker's acceptance, security purchase facility or similar credit transaction; (5) all obligations of the type referred to in clauses (1) through (4) above of other persons for the payment of which we are responsible or liable as obligor, guarantor or otherwise; and (6) all obligations of the type referred to in clauses (1) through (5) above of other persons secured by any lien on any property or asset of ours (whether or not such obligation is assumed by us), except for in all such cases (x) any such indebtedness that is by its terms subordinated to or pari passu with the subordinate debt securities and (y) any indebtedness between or among us or our affiliates, including all other debt securities and guarantees in respect of those debt securities issued to any trust, or trustee of such trust, partnership or other entity affiliated with us that is, directly or indirectly, a financing vehicle of ours (a 'Financing Entity') in connection with the issuance by such Financing Entity of preferred securities or other securities that rank pari passu with, or junior to, the subordinate debt securities. Except as provided in the applicable prospectus supplement, the subordinate indenture for a series of subordinated debt does not limit the aggregate amount of senior indebtedness that may be issued by us. The subordinate debt securities are effectively subordinated to all existing and future liabilities of our subsidiaries. By reason of such subordination, in the event of a distribution of assets upon insolvency, some of our general creditors may recover more, ratably, than holders of the subordinated debt securities. A subordinate indenture may provide that the subordination provisions thereof will not apply to money and securities held in trust pursuant to the satisfaction and discharge and the legal defeasance provisions of the subordinate indenture. If this prospectus is being delivered in connection with the offering of a series of subordinated debt securities, the accompanying prospectus supplement or the information incorporated by reference therein will set forth the approximate amount of senior indebtedness outstanding as of a recent date. CONSOLIDATION, MERGER AND SALE OF ASSETS Except as may otherwise be provided in the prospectus supplement, each indenture provides that we may not consolidate with or merge with or into any person, or convey, transfer or lease all or substantially all of our assets, or permit any person to consolidate with or merge into us, unless the following conditions have been satisfied: (a) either (1) we shall be the continuing person in the case of a merger or (2) the resulting, surviving or transferee person, if other than us (the 'Successor Company'), shall be a corporation organized and existing under the laws of the United States, any State or the District of Columbia and shall expressly assume all our obligations under the debt securities and the applicable indenture; (b) immediately after giving effect to the transaction (and treating any indebtedness that becomes an obligation of the Successor Company or any subsidiary of ours as a result of 15 the transaction as having been incurred by the Successor Company or the subsidiary at the time of the transaction), no default, Event of Default or event that, after notice or lapse of time, would become an Event of Default under the applicable indenture shall have occurred and be continuing; and (c) we shall have delivered to the trustee under each indenture an officers' certificate and an opinion of counsel, each stating that the consolidation, merger, transfer or lease complies with the provisions of the applicable indenture. Upon completion of any such transaction, the Successor Company resulting from such consolidation or into which we are merged or the transferee or lessee to which such conveyance, transfer or lease is made, will succeed to, and be substituted for, and may exercise every right and power of, us under each indenture, and thereafter, except in the case of a lease, the predecessor (if still in existence) will be released from its obligations and covenants under each indenture and all outstanding debt securities. NOTICES Except as otherwise provided in the indentures, notices to holders of debt securities will be given by mail to the addresses of such holders as they appear in the Security Register. CONVERSION OR EXCHANGE If and to the extent indicated in the applicable prospectus supplement, the debt securities of any series may be convertible or exchangeable into other securities. The specific terms on which debt securities of any series may be so converted or exchanged will be set forth in the applicable prospectus supplement. These terms may include provisions for conversion or exchange, either mandatory, at the option of the holder, or at our option, in which case the number of shares of other securities to be received by the holders of debt securities would be calculated as of a time and in the manner stated in the applicable prospectus supplement. TITLE Before due presentment of a debt security for registration of transfer, we, the trustee and any agent of ours or the trustee may treat the person in whose name such debt security is registered as the owner of such debt security for the purpose of receiving payment of principal of and any premium and any interest (other than defaulted interest or as otherwise provided in the applicable prospectus supplement) on such debt security and for all other purposes whatsoever, whether or not such debt security be overdue, and neither Sirius, the trustee nor any agent of ours or the trustee shall be affected by notice to the contrary. REPLACEMENT OF DEBT SECURITIES Any mutilated debt security will be replaced by us at the expense of the holder upon surrender of such debt security to the trustee. Debt securities that become destroyed, stolen or lost will be replaced by us at the expense of the holder upon delivery to the trustee of the debt security or evidence of the destruction, loss or theft thereof satisfactory to us and the trustee. In the case of a destroyed, lost or stolen debt security, an indemnity satisfactory to the trustee and us may be required at the expense of the holder of such debt security before a replacement debt security will be issued. GOVERNING LAW The indentures and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York. REGARDING THE TRUSTEE We may appoint a separate trustee for any series of debt securities. As used herein in the description of a series of debt securities, the term 'trustee' refers to the trustee appointed with respect to the series of debt securities. 16 The indentures contain certain limitations on the right of the trustee, should it become a creditor of ours, to obtain payment of claims in certain cases or to realize for its own account on certain property received in respect of any such claim as security or otherwise. The trustee will be permitted to engage in certain other transactions; however, if it acquires any conflicting interest and there is a default under the debt securities of any series for which the trustee serves as trustee, the trustee must eliminate such conflict or resign. The trustee or its affiliate may provide certain banking and financial services to us in the ordinary course of business. 17 DESCRIPTION OF CAPITAL STOCK Our amended and restated certificate of incorporation provides for authorized capital of 2,550,000,000 shares, consisting of 2,500,000,000 shares of common stock, par value $0.001 per share, and 50,000,000 shares of preferred stock, par value $0.001 per share. The following description sets forth the terms and provisions of our common stock and preferred stock. The terms of any shares of our capital stock offered by any prospectus supplement, but not set forth below, will be described in the prospectus supplement relating to such shares of capital stock. COMMON STOCK As of March 31, 2003, we had 911,666,616 shares of common stock outstanding beneficially held by approximately 75,000 persons, and had reserved for issuance 252,821,439 shares of common stock with respect to incentive stock plans and outstanding common stock purchase warrants. Holders of our common stock are entitled to cast one vote for each share held of record on all matters acted upon at any stockholder's meeting and to receive dividends if, as and when declared by our board of directors out of funds legally available therefor. There are no cumulative voting rights. If there is any liquidation, dissolution or winding-up of our company, each holder of our common stock will be entitled to participate, taking into account the rights of any outstanding preferred stock, ratably in all of our assets remaining after payment of liabilities. Holders of our common stock have no preemptive or conversion rights. All outstanding shares of our common stock, including shares of common stock issued upon the exercise of the common stock warrants, will be fully paid and non-assessable. Our common stock is quoted on the Nasdaq National Market under the symbol 'SIRI.' If the minimum bid price of our common stock closes below $1.00 per share for 30 or more consecutive trading days and we are unable to cure such defect, Nasdaq may delist our common stock from the Nasdaq National Market. On March 20, 2003, Nasdaq informed us that the minimum bid price of our common stock had closed below $1.00 for more than 30 consecutive trading days and that we had until September 16, 2003 to cure the defect. If our common stock fails to close above $1.00 for ten consecutive days prior to September 16, 2003, we have the right to request a hearing prior to delisting by Nasdaq. We intend to maintain the listing of our common stock on the Nasdaq National Market and expect to take all reasonable steps to preserve that listing. PREFERRED STOCK Our board of directors is authorized, subject to any limitations prescribed by law, without further stockholder approval, to issue from time to time up to an aggregate of 50,000,000 shares of our preferred stock, in one or more series. Each such series of preferred stock will have such number of shares, designations, preferences, powers, qualifications and special or relative rights or privileges as will be determined by our board of directors, which may include, among others, dividend rights, voting rights, redemption and sinking fund provisions, liquidation preferences, conversion rights and preemptive rights. The rights of the holders of our common stock will be subject to the rights of holders of any preferred stock issued in the future. The issuance of preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, a majority of our outstanding voting stock. In connection with our recent restructuring, all of our then outstanding preferred stock was retired and cancelled as of March 7, 2003. The specific terms of any preferred stock being offered will be described in the prospectus supplement relating to that preferred stock. The following summaries of the provisions of the preferred stock are subject to, and are qualified in their entirety by reference to, the certificate of 18 designation relating to the particular class or series of preferred stock. Reference is made to the prospectus supplement relating to the preferred stock offered with that prospectus for specific terms, including: the designation of the preferred stock; the number of shares of the preferred stock offered, the liquidation preference per share and the initial offering price of the preferred stock; the dividend rate(s), period(s) and/or payment date(s) or method(s) of calculating these items applicable to the preferred stock; the date from which dividends on the preferred stock will accumulate, if applicable; the procedures for any auction and remarketing of the preferred stock; the provision of a sinking fund, if any, for the preferred stock; the provision for redemption, if applicable, of the preferred stock; any listing of the preferred stock on any securities exchange; the terms and conditions, if applicable, upon which the preferred stock will be convertible into or exchangeable for common stock, and whether at our option or the option of the holder; whether the preferred stock will rank senior or junior to or on a parity with any other class or series of preferred stock; the voting rights, if any, of the preferred stock; any other specific terms, preference, rights, limitations or restrictions of the preferred stock; and a discussion of United States federal income tax considerations applicable to the preferred stock. PREFERRED STOCK PURCHASE RIGHTS On October 22, 1997, our board of directors adopted a stockholders rights plan and, in connection with the adoption of this plan, declared a dividend distribution of one 'Right' for each outstanding share of common stock to stockholders of record at the close of business on November 3, 1997 (the 'Rights Record Date'). Except as described below, each Right entitles the registered holder of the Right to purchase from us one-hundredth of a share of Series B Preferred Stock, par value $0.001 per share (the 'Series B Shares'), at a purchase price of $115.00 (the 'Purchase Price'), which may be adjusted. The Purchase Price shall be paid in cash. The description and terms of the Rights are set forth in a Rights Agreement, dated October 22, 1997 (the 'Rights Agreement'), by and between us and The Bank of New York (the successor to Continental Stock Transfer & Trust Company), as Rights Agent, and in amendments to the Rights Agreement dated October 13, 1998, November 13, 1998, December 22, 1998, June 11, 1999, September 29, 1999, December 23, 1999, January 28, 2000, August 7, 2000, January 8, 2002, October 2002, March 6, 2003 and March 31, 2003. On March 6, 2003, we amended the Rights Agreement to (1) render the Rights Agreement inapplicable to the issuance of common stock to Lehman Commercial Paper Inc. in the restructuring transactions and to permit Lehman to acquire up to an additional 1% of the outstanding shares of common stock, without Lehman becoming an 'Acquiring Person' within the meaning of the Rights Agreement and (2) permit each of OppenheimerFunds, Inc., Apollo Management, L.P., The Blackstone Group L.P. and their respective affiliates and affiliated investment funds to acquire up to 25% of the outstanding shares of common stock, without becoming 'Acquiring Persons' within the meaning of the Rights Agreement. Initially, no separate Right certificates were distributed and the Rights were evidenced, with respect to any shares of common stock outstanding on the Rights Record Date, by the certificates representing the shares of common stock. Until the Rights Separation Date (as defined below), the 19 Rights will be transferred with, and only with, certificates for shares of common stock. Until the earlier of the Rights Separation Date and the redemption or expiration of the Rights, new certificates for shares of common stock issued after the Rights Record Date will contain a notation incorporating the Rights Agreement by reference. The Rights are not exercisable until the earlier to occur of (1) 10 business days following a public announcement that a person or group of affiliated or associated persons (an 'Acquiring Person') has acquired, or obtained the right to acquire, beneficial ownership of 15% or more of the outstanding shares of common stock (except by reason of (a) exercise by this person of stock options granted to this person by us under any of our stock option or similar plans (b) the exercise of conversion rights contained in specified classes of Preferred Stock, or (c) the exercise of warrants owned on the date of the Rights Agreement, which include warrants to acquire 1,740,000 shares of common stock issued to an affiliate of Everest Capital Fund, Ltd. or (2) 15 business days following the commencement of a tender offer or exchange offer by any person (other than Sirius, any subsidiary of Sirius or any employee benefit plan of Sirius) if, upon the completion of this tender offer or exchange offer, this person or group would be the beneficial owner of 15% or more of the outstanding shares of common stock (the earlier of these dates being called the 'Rights Separation Date'), and will expire on August 1, 2003, unless earlier extended or redeemed by us as described below. As soon as practicable following the Rights Separation Date, separate certificates evidencing the Rights will be mailed to holders of record of the shares of common stock as of the close of business on the Rights Separation Date and, thereafter, the separate Rights certificates alone will evidence the Rights. A holder of 15% or more of the common stock as of the date of the Rights Agreement will be excluded from the definition of 'Acquiring Person' unless the holder increases the aggregate percentage of its and its affiliates' beneficial ownership interest in us by an additional 1%. If, at any time following the Rights Separation Date, (1) we are the surviving corporation in a merger with an Acquiring Person and our shares of common stock are not changed or exchanged, (2) a person (other than Sirius, any subsidiary of Sirius or any employee benefit plan of Sirius), together with its Affiliates and Associates (as defined in the Rights Agreement), becomes an Acquiring Person (in any manner, except by (a) the exercise of stock options granted under our existing and future stock option plans, (b) the exercise of conversion rights contained in specified preferred stock issues, (c) the exercise of warrants specified in the Rights Agreement or (d) a tender offer for any and all outstanding shares of common stock made as provided by applicable laws, which remains open for at least 40 Business Days (as defined in the Rights Agreement) and into which holders of 80% or more of our outstanding shares of common stock tender their shares), (3) an Acquiring Person engages in one or more 'self-dealing' transactions as described in the Rights Agreement or (4) during the time when there is an Acquiring Person, an event occurs (e.g., a reverse stock split), that results in the Acquiring Person's ownership interest being increased by more than one percent, the Rights Agreement provides that proper provision shall be made so that each holder of a Right will thereafter be entitled to receive, upon the exercise of the Right at the then current exercise price of the Right, shares of common stock (or, in some circumstances, cash, property or other securities of ours) having a value equal to two times the exercise price of the Right. If, at any time following the first date of public announcement by us or an Acquiring Person indicating that this Acquiring Person has become an Acquiring Person (the 'Shares Acquisition Date'), (1) we consolidate or merge with another person and we are not the surviving corporation, (2) we consolidate or merge with another person and are the surviving corporation, but in the transaction our shares of common stock are changed or exchanged or (3) 50% or more of our assets or earning power is sold or transferred, the Rights Agreement provides that proper provision shall be made so that each holder of a Right shall thereafter have the right to receive, upon the exercise of the Right at the then current exercise price of the Right, shares of common stock of the acquiring company having a value equal to two times the exercise price of the Right. Our board of directors may, at its option, at any time after the right of the board to redeem the Rights has expired or terminated (with some exceptions), exchange all or part of the then outstanding and exercisable Rights (other than those held by the Acquiring Person and Affiliates 20 and Associates of the Acquiring Person) for shares of common stock at a ratio of one share of common stock per Right, as adjusted; provided, however, that the Right cannot be exercised once a person, together with the person's Affiliates and Associates, becomes the beneficial owner of 50% or more of the shares of common stock then outstanding. If our board of directors authorizes this exchange, the Rights will immediately cease to be exercisable. Notwithstanding any of the foregoing, following the occurrence of any of the events described in the fourth and fifth paragraphs of this section, any Rights that are, or (under some circumstances specified in the Rights Agreement) were, beneficially owned by any Acquiring Person or Affiliate or Associate of an Acquiring Person shall immediately become null and void. The Rights Agreement contains provisions intended to prevent the utilization of voting trusts or similar arrangements that could have the effect of rendering ineffective or circumventing the beneficial ownership rules described in the Rights Agreement. The Purchase Price payable, and the number of Series B Shares or other securities or property issuable, upon exercise of the Rights may be adjusted from time to time to prevent dilution (1) in the event of a dividend of Series B Shares on, or a subdivision, combination or reclassification of, the Series B Shares, (2) upon the grant to holders of the Series B Shares of specific rights or warrants to subscribe for Series B Shares or securities convertible into Series B Shares at less than the current market price of the Series B Shares or (3) upon the distribution to holders of the Series B Shares of debt securities or assets (excluding regular quarterly cash dividends and dividends payable in Series B Shares) or of subscription rights or warrants (other than those referred to above). At any time after the date of the Rights Agreement until ten Business Days (a period that can be extended) following the Shares Acquisition Date, the board of directors, with the concurrence of a majority of the independent directors (those members of our board who are not officers or employees of ours or of any subsidiary of ours and who are not Acquiring Persons or their Affiliates, Associates, nominees or representatives, and who either (1) were members of the board before the adoption of the Rights Plan or (2) were subsequently elected to our board and were recommended for election or approved by a majority of the independent directors then on our board), may redeem the Rights, in whole but not in part, at a price of $0.01 per Right, which may be adjusted. Thereafter, our board of directors may redeem the Rights only in specified circumstances including in connection with specific events not involving an Acquiring Person or an Affiliate or Associate of an Acquiring Person. In addition, our right of redemption may be reinstated if (1) an Acquiring Person reduces its beneficial ownership to 10% or less of the outstanding shares of common stock in a transaction or series of transactions not involving us and (2) there is at the time no other Acquiring Person. The Rights Agreement may also be amended, as described below, to extend the period of redemption. Until a Right is exercised, the holder of the Right, as such, will have no rights as a stockholder, including the right to vote or to receive dividends. While the distribution of the Rights will not be taxable to stockholders or to us, stockholders may, depending upon the circumstances, recognize taxable income if the Rights become exercisable for shares of our common stock (or other consideration) or for shares of common stock of the Acquiring Person. Other than those provisions relating to the principal economic terms of the Rights or imposing limitations on the right to amend the Rights Agreement, any of the provisions of the Rights Agreement may be amended by our board of directors with the concurrence of a majority of the independent directors or by special approval of our stockholders before the Rights Separation Date. Thereafter, the period during which the Rights may be redeemed may be extended (by action of our board of directors, with the concurrence of a majority of the independent directors or by special approval of our stockholders), and other provisions of the Rights Agreement may be amended by action of our board of directors with the concurrence of a majority of the independent directors or by special approval of our stockholders; provided, however, that (a) this amendment will not adversely affect the interests of holders of Rights (excluding the interests of any Acquiring Person) and (b) no amendment shall be made at a time when the Rights are no 21 longer redeemable (except for the possibility of the right of redemption being reinstated as described above). DELAWARE ANTI-TAKEOVER LAW AND PROVISIONS IN OUR CHARTER Section 203 of the Delaware General Corporation Law ('Section 203') generally provides that a stockholder acquiring more than 15% of the outstanding voting stock of a corporation subject to the statute (an 'Interested Stockholder') but less than 85% of this stock may not engage in some types of Business Combinations (as defined in Section 203) with the corporation for a period of three years after the time the stockholder became an Interested Stockholder. The prohibition of Section 203 does not apply under the following circumstances: before the time of the acquisition, the corporation's board of directors approved either the Business Combination or the transaction in which the stockholder became an Interested Stockholder; or the Business Combination is approved by the corporation's board of directors and authorized at a stockholders' meeting by a vote of at least two-thirds of the corporation's outstanding voting stock not owned by the Interested Stockholder. Under Section 203, these restrictions will not apply to specific Business Combinations proposed by an Interested Stockholder following the earlier of the announcement or notification of specific extraordinary transactions involving the corporation and a person who was not an Interested Stockholder during the previous three years, who became an Interested Stockholder with the approval of the corporation's board of directors or who became an Interested Stockholder at a time when the restrictions contained in Section 203 did not apply for reasons specified in Section 203. The above exception applies if the extraordinary transaction is approved or not opposed by a majority of the directors who were directors prior to the person becoming an Interested Stockholder during the previous three years or were recommended for election or elected to succeed those directors by a majority of those directors. Section 203 defines the term 'Business Combination' to encompass a wide variety of transactions with or caused by an Interested Stockholder. These include transactions in which the Interested Stockholder receives or could receive a benefit on other than a pro rata basis with other stockholders, transactions with the corporation which increase the proportionate interest in the corporation directly or indirectly owned by the Interested Stockholder or transactions in which the Interested Stockholder receives other benefits. The provisions of Section 203, coupled with our board of directors' authority to issue preferred stock without further stockholder action, could delay or frustrate the removal of incumbent directors or a change in our control. The provisions could also discourage, impede or prevent a merger, tender offer or proxy contest, even if the event would be favorable to the interests of stockholders. Our stockholders, by adopting an amendment to our amended and restated certificate of incorporation, may elect not to be governed by Section 203 effective 12 months after the adoption. Neither our certificate of incorporation nor our by-laws exclude us from the restrictions imposed by Section 203. DESCRIPTION OF WARRANTS We may issue warrants for the purchase of debt securities, preferred stock, common stock or any combination thereof. Warrants may be issued independently or together with any other securities offered in an applicable prospectus supplement and may be attached to or separate from such securities. Warrants may be issued under warrant agreements (each, a 'warrant agreement') to be entered into between us and a warrant agent specified in the applicable prospectus supplement.

PLAN OF DISTRIBUTION We may sell the securities: to one or more underwriters or dealers for public offering and sale by them; and to investors directly or through agents. The distribution of securities may be effected from time to time in one or more transactions at a fixed price or prices (which may be changed from time to time), at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. Each prospectus supplement will describe: the method of distribution of the securities offered thereby; the purchase price and the proceeds we will receive from the sale; and any securities exchanges on which the securities of such series may be listed. In connection with the sale of the securities, underwriters, dealers or agents may receive compensation from us or from purchasers of the securities for whom they may act as agents, in the form of discounts, concessions or commissions. The underwriters, dealers or agents that participate in the distribution of the securities may be deemed to be underwriters under the Securities Act and any discounts or commissions received by them and any profit on the resale of the securities received by them may be deemed to be underwriting discounts and commissions thereunder. Any such underwriter, dealer or agent will be identified and any such compensation received from us will be described in the applicable prospectus supplement. Any initial public offering price and any discounts or concessions allowed or paid to dealers may be changed from time to time. Under the agreements that may be entered into with us, underwriters, dealers and agents may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the underwriters, dealers or agents may be required to make in respect thereof. Each underwriter, dealer and agent participating in the distribution of any securities that are issuable in bearer form will agree that it will not offer, sell, resell or deliver, directly or indirectly, securities in bearer form to persons located in the United States or to United States persons 26 (other than qualifying financial institutions), in connection with the original issuance of the securities. Certain of the underwriters or agents and their associates may be customers of, engage in transactions with and perform services for us in the ordinary course of business. Certain persons participating in an offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities, including over-allotment, stabilizing and short-covering transactions in such securities, the imposition of a penalty bid, and bidding for and purchasing shares of our common stock in the open market during and after an offering. LEGAL MATTERS Simpson Thacher & Bartlett, New York, New York, will pass upon specific legal matters under state law with respect to the securities. From time to time, Simpson Thacher & Bartlett represents The Blackstone Group L.P. on various matters in the regular course of business. Affiliates of Blackstone hold shares of our common stock. Certain partners of Simpson Thacher & Bartlett, members of their families, and related persons, have an indirect interest, through limited partnerships, in less than 1% of our common stock through a fund affiliated with Blackstone. EXPERTS Our audited consolidated financial statements appearing in our Annual Report on Form 10-K as of December 31, 2002 and for the year then ended have been audited by Ernst & Young LLP, independent auditors, as set forth in their report thereon included therein and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such report given on authority of such firm as experts in accounting and auditing. Our audited consolidated financial statements appearing in our Annual Report on Form 10-K as of December 31, 2001 and for each of the two years in the period ended December 31, 2001 have been audited by Arthur Andersen LLP, independent public accountants, as set forth in their report thereon included therein and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such report given on the authority of such firm as experts in accounting and auditing. Section 11(a) of the Securities Act provides that if a registration statement at the time it becomes effective contains an untrue statement of a material fact, or omits a material fact required to be stated therein or necessary to make the statements therein not misleading, any person acquiring a security pursuant to such registration statement (unless it is proven that at the time of such acquisition such person knew of such untruth or omission) may assert a claim against, among others, an accountant who has consented to be named as having certified any part of the registration statement or as having prepared any report for use in connection with the registration statement. On April 11, 2002, we dismissed Arthur Andersen LLP as our independent auditors and appointed Ernst & Young LLP. Prior to the date of this prospectus, the Arthur Andersen partner responsible for the audit of our most recent audited financial statements as of and for the year ended December 31, 2001 resigned from Arthur Andersen LLP. As a result, after reasonable efforts, we have been unable to obtain Arthur Andersen's written consent to the incorporation by reference into this prospectus of its audit reports with respect to our consolidated financial statements as of December 31, 2001 and for each of the two years in the period ended December 31, 2001. Under these circumstances, Rule 437a under the Securities Act permits us to file this prospectus without a written consent from Arthur Andersen LLP. However, as a result, Arthur Andersen LLP will not have any liability under Section 11(a) of the Securities Act for any untrue statements of a material fact contained in the consolidated financial statements audited by Arthur Andersen LLP or any omissions of a material fact required to be stated therein. Accordingly, you will be unable to assert a claim against Arthur Andersen LLP under Section 11(a) of the Securities Act because it has not consented to the incorporation by reference of its previously issued report into this prospectus. 27 INCORPORATION BY REFERENCE The SEC allows us to 'incorporate by reference' in this prospectus other information we file with them, which means that we can disclose important information to you by referring you to those documents.
