(“Sirius”), pursuant to the terms of an Agreement and Plan of Merger, dated as of February 19, 2007, as it may be amended, modified or extended (the “Merger Agreement”), among XM Holdings, Merger Sub and Sirius, or other business combination in which XM Holdings and Sirius become affiliated (the “Merger”) may trigger certain obligations of the Company pursuant to the Indenture.

NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each of the parties signatory to this Agreement hereby agrees as follows:

1. Waiver. Each of the Beneficial Noteholders hereby irrevocably agrees and consents that, to the extent that the consummation of the Merger constitutes a “Change of Control” as defined under Section 1.01 of the Indenture, the requirements pursuant to Section 4.14 (Offer to Repurchase Upon Change of Control) of the Indenture that the Company repurchase Notes or make an offer to the holders of the Notes to repurchase the Notes and to give notice of such Change of Control or Offer to Repurchase Upon a Change of Control are, subject to the other provisions of this Agreement, hereby waived in respect of such “Change of Control” (the “Waiver”). The Waiver will be set forth in a supplemental indenture substantially in the form attached hereto as Exhibit A, and pursuant to the terms of the Indenture all holders of the Notes will be bound thereby. The Trustee is hereby instructed by each of the Beneficial Noteholders, and will be instructed by the registered holders under Section 4, to execute the supplemental indenture referred to in the preceding sentence. Each Beneficial Noteholder acknowledges and agrees that the Waiver shall be binding upon their respective successors, assigns, trustees in bankruptcy and other legal representatives.

2. Termination of Effectiveness.

(a) The Waiver shall become effective upon signing and shall cease to be effective as of August 31, 2008 unless the following events have occurred on or prior to such date:

(i) the consummation of the Merger;

(ii) the Company having caused funds to be raised in the amount of at least $400,000,000 through the issuance of (A) a new series of senior notes (the “New Senior Notes”) or (B) other securities, both of which will be equal to or junior in right of payment to the Exchange Notes (as defined in Section 3 below), to fund the cash portion of the consideration payable in the Exchange Offer (as defined below);

(iii) the Company or XM Holdings having raised at least $500,000,000 through a contribution to the Company’s equity capital, the issuance and sale of convertible or exchangeable notes that will be junior in right of payment to the Exchange Notes or the issuance and sale of equity securities (it being understood that, the financing conditions in subsection (ii) above and this subsection (iii) are independent of each other resulting in an aggregate condition of $900,000,000 of financing);

(iv) the Company or XM Holdings having funded or contributed the necessary funds into a segregated account to fund the mandatory offer to repurchase all Senior Floating Rate Notes due 2013 of XM Inc. (the “Floating Rate Notes”) triggered by the Merger;

(v) the Company or XM Holdings having funded or contributed the necessary funds into a segregated account to fund the mandatory offer to repurchase transponders of the XM-4 satellite, triggered by the Merger under the sale and leaseback transaction pursuant to (A) the Participation Agreement, dated as of February 13, 2007, by and among XM Holdings, ▇▇▇▇▇ Fargo Bank Northwest in its capacity as Owner Trustee and other parties, (B) the lease agreement, dated as of February 13, 2007, by and between ▇▇▇▇▇ Fargo Bank Northwest, as Owner Trustee, and the Company and (C) the other related documents (the “Sale-Leaseback Transaction”);

(vi) the Company or XM Holdings having repaid all borrowings under Section 13 and related “credit facility” portions of the Third Amended and Restated Distribution and Credit Agreement, dated as of February 6, 2008, by and among General Motors Corporation, XM Holdings and XM Inc.;

(vii) with respect to XM Holdings’ 1.75% Convertible Senior Notes due 2009 (the “Convertible Senior Notes”), XM Holdings having obtained the consent of holders of at least 98% of the aggregate principal amount of such Convertible Senior Notes to waive a change of control offer, if any, triggered by the Merger with the interest rate on such Convertible Senior Notes to be increased to 10% subject to the Merger being completed; and

(viii) the absence of any occurrence of an event that, with notice or lapse of time or both, would constitute a default, in the due performance or observance of any term, covenant or condition contained in the indenture governing the Exchange Notes (as defined below).

3. The Company’s Obligations to Make the Exchange Offer. The Company agrees to commence the exchange offer for the Notes held by the Beneficial Noteholders and other “qualified institutional buyers” (as defined in the Securities Act) (“QIBs”) (and at the Company’s option, the other registered holders of the Notes) for $600,000,000 (assuming the offer is for all outstanding Notes) of aggregate consideration which shall be paid (a) two thirds in cash and (b) the remaining one third in new senior unsecured notes (the “Exchange Notes”) on the terms and conditions set forth in the description of notes attached hereto as Exhibit B hereto (the “Exchange Offer”); provided, that for each dollar in excess of $400,000,000 raised by the Company in the offering contemplated by Section 2(a)(ii) hereof (other than securities that rank junior in right of payment to Exchange Notes), the Company will increase the cash portion and concurrently reduce the Exchange Notes portion of the consideration in the Exchange Offer. The Exchange Notes will have the same coupon as the New Senior Notes. The exchange ratio for each $1000 principal amount of Notes exchanged in the Exchange Offer will be $1,000 divided by the price on the Exchange Notes (expressed as a decimal) that equates to a yield to maturity (to the investor) of the greater of (a) 13.92% or (b) the yield to maturity of the New Senior Notes (calculated solely based on the coupon of the New Senior Notes and the price at which they are sold to investors). If less than $150 million of New Senior Notes are issued, then the coupon of the Exchange Notes will be 13% and the yield to maturity used to calculate the exchange ratio will be the greater of (a) 15% or (b) the yield to maturity of the New Senior Notes (calculated solely based on the coupon of the New Senior Notes and the price at which they are sold to investors). The Company agrees that it will commence the Exchange Offer as promptly as practicable following the Merger, but in no event later than five business days following the consummation of the Merger and to do all things reasonably necessary and appropriate in furtherance thereof, including filing any related documents with the Securities and Exchange Commission (the “Commission”), if applicable, and to use its best efforts to consummate the Exchange Offer within 30 business days of its commencement.

4. Instruction to Registered Holders. Section 9.02 of the Indenture provides that the Holders (defined as the registered holders) of a majority in aggregate principal amount of the Notes then outstanding may waive compliance with certain provisions of the Indenture, subject to the limitations set forth therein. Each of the Beneficial Noteholders hereby covenants and agrees to instruct its registered holder or holders of the Notes to execute a waiver, as of the date hereof, substantially in the form attached hereto as Exhibit C, implementing the Waiver and instructing the Trustee to execute the supplemental indenture referred to in Section 1 and agrees to take any additional action as may be reasonably requested by the Company in order to give effect to the Waiver and to make the supplemental indenture effective.

5. Effectiveness of this Agreement. This Agreement shall become effective immediately upon the execution hereof by the parties listed on the signature pages hereto.

6. Termination of Agreement. Notwithstanding anything to the contrary set forth in this Agreement, this Agreement and the Waiver shall terminate upon termination of the Merger Agreement without the Merger having been consummated upon or prior to such termination.

The Company issued the Outstanding Notes in denominations of $1,000 and any integral multiple of $1,000. As long as we are subject to the debt incurrence covenants under the Existing Sale and Leaseback Transaction and subject to the indentures governing the Company’s 9.75% Senior Notes due 2014 or the Company’s Senior Floating Rate Notes due 2013, the Notes will have a maturity of , 2014. If at any time prior to , 2013, the Company is no longer either (i) subject to the debt incurrence covenants under the Existing Sale and Leaseback Transaction or (ii) subject to the indentures governing the Company’s 9.75% Senior Notes due 2014 and the Company’s Senior Floating Rate Notes due 2013, to the extent any notes issued thereunder remain outstanding following the refinancing

transactions described in this offering memorandum, the Notes will mature on , 2013. Subject to our compliance with the covenant described under the subheading “—Certain covenants—Limitation on indebtedness”, we will be permitted to issue more Notes from time to time under the Indenture (the “Additional Notes”). The Notes and the Additional Notes, if any, will be treated as a single class for all purposes of the Indenture, including waivers, amendments, redemptions and offers to purchase. Unless the context otherwise requires, for all purposes of the Indenture and this “Description of Notes”, references to the Notes include any Additional Notes actually issued.

Interest on these Notes will accrue at the rate of % per annum and will be payable semiannually in arrears on and of each year, commencing on . We will make each interest payment to the holders of record of these Notes on the immediately preceding and . We will pay interest on overdue principal at 1% per annum in excess of the above rate and will pay interest on overdue installments of interest at such higher rate to the extent lawful.

Interest on these Notes will accrue from the date of original issuance or, if interest has already been paid, from the most recent interest payment date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Payments on the Notes; paying agent and registrar

We will pay principal of, premium, if any, and interest on the Notes at the office or agency designated by the Company in the Borough of Manhattan, The City of New York, except that we may, at our option, pay interest on the Notes by check mailed to holders of the Notes at their registered address as it appears in the Registrar’s books. We have initially designated the corporate trust office of the Trustee in New York, New York to act as our Paying Agent and Registrar. We may, however, change the Paying Agent or Registrar without prior notice to the holders of the Notes, and the Company or any of its Restricted Subsidiaries may act as Paying Agent or Registrar.

We will pay principal of, premium, if any, and interest on, Notes in global form registered in the name of or held by The Depository Trust Company or its nominee in immediately available funds to The Depository Trust Company or its nominee, as the case may be, as the registered holder of such global Note.

Transfer and exchange

A holder may transfer or exchange Notes in accordance with the Indenture. The Registrar and the Trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents. No service charge will be imposed by the Company, the Trustee or the Registrar for any registration of transfer or exchange of Notes, but the Company may require a holder to pay a sum sufficient to cover any transfer tax or other governmental taxes and fees required by law or permitted by the Indenture. The Company is not required to transfer or exchange any Note selected for redemption. Also, the Company is not required to transfer or exchange any Note for a period of 15 days before a selection of Notes to be redeemed.

The registered holder of a Note will be treated as the owner of it for all purposes.

Optional redemption

We may, at our option, redeem some or all of the Notes at any time and from time to time at a redemption price equal to the greater of the following amounts, plus, in each case, accrued and unpaid interest on the principal amount being redeemed to the applicable redemption date:

	•		100% of the principal amount of the Notes to be redeemed; and

	•		the sum of the present values of the principal amount and the remaining scheduled payments of interest on the Notes to be redeemed (not including any portion of payments of interest accrued as of the applicable redemption date), discounted to the applicable redemption date in accordance with customary market practice on a semi-annual basis at a rate equal to the sum of the Treasury Rate plus 0.50%.

The redemption prices will be calculated by the Independent Investment Banker assuming a 360-day year consisting of twelve 30-day months. For purposes of calculating the redemption prices, the following terms will have the meanings set forth below.

“Comparable Treasury Issue” means the U.S. Treasury security or securities selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Notes to be redeemed that would be used, at the time of selection and in accordance with customary market practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of such Notes.

“Comparable Treasury Price” means, with respect to any redemption date,

	•		the bid-side price for the Comparable Treasury Issue as of the third Business Day preceding the redemption date, as set forth in the daily statistical release (or any successor release) published by the Wall Street Journal in the table entitled “Treasury Bonds, Notes, and Bills,” as determined by the Independent Investment Banker, or

	•		if such release (or any successor release) is not published or does not contain such prices on such Business Day:

	o		the average of the Reference Treasury Dealer Quotations for that redemption date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations;

	o		if the Trustee obtains fewer than four Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received; or

	o		if only one Reference Treasury Dealer Quotation is received, such quotation.

“Independent Investment Banker” means one of the Reference Treasury Dealers selected by the Trustee after consultation with us.

“Reference Treasury Dealer” means each of four primary U.S. Government securities dealers in New York City (each a “Primary Treasury Dealer”), consisting of (i) ▇.▇. ▇▇▇▇▇▇ Securities Inc. (or its affiliate), (ii) ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated (or its affiliate), (iii) UBS Securities LLC and (iv) another nationally recognized investment banking firm (or its affiliate) that we select in connection with the particular redemption, and their respective successors, provided that if any of them ceases to be a Primary Treasury Dealer, we will substitute another nationally recognized investment banking firm (or its affiliate) that is a Primary Treasury Dealer.

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

“Treasury Rate” means, with respect to any redemption date, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated on the third Business Day preceding the applicable redemption date, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date.

Unless we default in the payment of the redemption price, on and after the applicable redemption date, interest will cease to accrue on the Notes or portions of the Notes called for redemption.

If the optional redemption date is on or after an interest record date and on or before the related interest payment date, the accrued and unpaid interest, if any, will be paid to the Person in whose name the Note is registered at the close of business, on such record date, and no additional interest will be payable to holders whose Notes will be subject to redemption by the Company.

Selection and notice of redemption

If we are redeeming less than all the Notes at any time, the Registrar will select Notes to be redeemed using any method that it deems fair and appropriate. However, if the Notes are solely registered in the name of Cede & Co. and traded through The Depository Trust Company, then The Depository Trust Company will select the Notes to be redeemed in accordance with its practices.

We will redeem Notes of $1,000 or less in whole and not in part. We will cause notices of redemption to be mailed by first-class mail at least 30 but not more than 60 days before the redemption date to each holder of Notes to be redeemed at its registered address.

If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the portion of the principal amount thereof to be redeemed. We will issue a new Note in a principal amount equal to the unredeemed portion of the original Note in the name of the holder upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption.

Mandatory redemption; offers to purchase; open market purchases

We are not required to make any mandatory redemption or sinking fund payments with respect to the Notes. However, under certain circumstances, we may be required to offer to purchase Notes as described under the captions “—Change of control” and “—Certain covenants—Limitation on sales of assets and subsidiary stock”. We may at any time and from time to time purchase Notes in the open market or otherwise.

Ranking

Senior indebtedness versus Notes

The indebtedness evidenced by these Notes will be unsecured and will rank pari passu in right of payment to any other Senior Indebtedness of the Company. Secured debt and other secured obligations of the Company will be effectively senior to the Notes to the extent of the value of the assets securing such debt or other obligations.

As of March 31, 2008, on a pro forma basis after giving effect to the refinancing transactions described in this offering memorandum, including the offering of the Notes and the application of the proceeds therefrom, Holdings, the Company and the Subsidiary Guarantors would have had approximately $2,107.6 million of Indebtedness outstanding, of which $407.6 million is secured Indebtedness. The amounts we will receive as a result of the refinancing transactions described in this offering memorandum may vary from those described in this offering memorandum depending on several factors, including changes in our refinancing plans as a result of market conditions or other factors, the extent to which holders of existing indebtedness may elect not to accept our offer to refinance their indebtedness, the timing of the merger and other factors. For more information on the sources and uses of proceeds associated with the refinancing transactions described in this offering memorandum, you should read the table under the caption “Use of proceeds” as well as “The merger,” “Capitalization” and “Summary of historical consolidated financial data” appearing elsewhere in this offering memorandum.

Liabilities of subsidiaries versus Notes

A portion of our operations are conducted through our Subsidiaries. Claims of creditors of Subsidiaries that are not Subsidiary Guarantors, including trade creditors and creditors holding indebtedness issued by such non-Guarantor Subsidiaries, and claims of preferred stockholders of such non-Guarantor Subsidiaries generally will have priority with respect to the assets and earnings of such non-Guarantor Subsidiaries over the claims of our creditors, including holders of the Notes. Accordingly, the Notes will be effectively subordinated to creditors (including trade creditors) and preferred stockholders, if any, of our non-Guarantor Subsidiaries.

As of March 31, 2008, on a pro forma basis after giving effect to the refinancing transactions described in this offering memorandum, including the offering of the Notes, non-Guarantor Subsidiaries would have had $25.9 million of liabilities, including trade and other payables.

Although the Indenture limits the Incurrence of Indebtedness and preferred stock by certain of our Subsidiaries, such limitation is subject to a number of significant qualifications. Moreover, the Indenture does not impose any limitation on the Incurrence by such Subsidiaries of liabilities that are not considered Indebtedness under the Indenture. See “—Certain covenants—Limitation on indebtedness”.

Note Guarantees

Upon consummation of the Escrow LLC-Company Merger, the Notes will be guaranteed by Holdings and each of the Company’s current and future Material Subsidiaries. Currently, XM Equipment Leasing LLC and XM Radio Inc. (to the extent permitted by FCC rules and regulations) are the only Subsidiary Guarantors. These Note Guarantees will be joint and several obligations of the Guarantors. The Subsidiary Guarantees will be effectively subordinated to any secured Indebtedness of the applicable Guarantor to the extent of the value of the assets securing such Indebtedness. The obligations of each Guarantor under its Note Guarantee will be limited as necessary to prevent that Note Guarantee from constituting a fraudulent conveyance under applicable law. See “Risk Factors—Federal and state statutes allow courts, under specific circumstances, to void or subordinate guarantees and require noteholders to return payments received from guarantors.”

A Guarantor may not sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless:

(1) immediately after giving effect to that transaction, no Default or Event of Default exists; and

(2) either:

(a) the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger assumes all the obligations of that Guarantor under the Indenture and its Note Guarantee pursuant to a supplemental indenture satisfactory to the Trustee; or

(b) the Net Proceeds of such sale or other disposition are applied in accordance with the applicable “Asset Sale” provisions of the Indenture.

The Note Guarantee of a Guarantor will be released with respect to the Notes:

(1) in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary

of the Company, if the sale or other disposition does not violate the “Asset Sale” provisions of the Indenture;

(2) in connection with any sale or other disposition of all of the Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate the “Asset Sale” provisions of the Indenture;

(3) if the Company designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of the Indenture; or

(4) upon legal defeasance or satisfaction and discharge of the Indenture as provided below under the captions “—Defeasance” and “—Satisfaction and discharge.”

See “—Limitation on sales of assets and subsidiary stock.”

Book-entry, delivery and form

The Notes will initially be represented in the form of one or more global notes (the “Global Notes”) in fully-registered book-entry form without interest coupons that will be deposited upon issuance with the Trustee under the Indenture, The Bank of New York Mellon, as custodian for The Depository Trust Company, or “DTC,” and registered in the name of DTC or its nominee, in each case for credit to an account of a direct or indirect participant as described below.

Except as set forth below, the global notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the global notes may not be exchanged for notes in certificated form (the “Certificated Notes”) except in the limited circumstances described below. See “—Exchange of global notes for certificated notes.” In addition, transfer of beneficial interests in the global notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants, which may change from time to time. The Notes may be presented for registration of transfer and exchange at the Corporate Trust Office of the Trustee.

Depository procedures

The following description of the operations and procedures of DTC is provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. We take no responsibility for these operations and procedures and urge investors to contact the system or their participants directly to discuss these matters.

DTC has advised us that DTC is a limited-purpose trust company organized under the laws of the State of New York, a “banking organization” within the meaning of the New York Banking Law, 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. DTC was created to hold securities for its participating organizations (collectively, the “participants”) and to facilitate the clearance and

settlement of transactions in those securities between participants through electronic book-entry changes in accounts of its participants. The participants include securities brokers and dealers (including the initial purchasers of the Outstanding Notes), banks, trust companies, clearing corporations and certain other organizations. Access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly (collectively, the "indirect participants”). Persons who are not participants may beneficially own securities held by or on behalf of DTC only through the participants or the indirect participants. The ownership interests in, and transfers of ownership interests in, each security held by or on behalf of DTC are recorded on the records of the participants and indirect participants.

DTC has also advised us that, pursuant to procedures established by it:

	(1)		upon deposit of the Global Notes, DTC will credit the accounts of participants designated by the initial purchasers of the Outstanding Notes with portions of the principal amount of the Global Notes; and

	(2)		ownership of these interests in the Global Notes will be shown on, and the transfer of ownership of these interests will be effected only through, records maintained by DTC (with respect to the participants) or by the participants and the indirect participants (with respect to other owners of beneficial interests in the Global Notes).

Investors in the Global Notes who are participants in DTC’s system may hold their interests therein directly through DTC. Investors in the Global Notes who are not participants may hold their interests therein indirectly through organizations which are participants in such system. All interests in a Global Note may be subject to the procedures and requirements of DTC. The laws of some states require that certain Persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer beneficial interests in a Global Note to such Persons will be limited to that extent. Because DTC can act only on behalf of participants, which in turn act on behalf of indirect participants, the ability of a Person having beneficial interests in a Global Note to pledge such interests to Persons that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests.

Except as described below, owners of an interest in the Global Notes will not have Notes registered in their names, will not receive physical delivery of Notes in certificated form and will not be considered the registered owners or “Holders” thereof under the Indenture for any purpose.

Payments in respect of the principal of, and interest and premium and additional interest, if any, on a Global Note registered in the name of DTC or its nominee will be payable to DTC in its capacity as the registered Holder under the Indenture. Under the terms of the Indenture, the Company and the Trustee will treat the Persons in whose names the Notes, including the Global Notes, are registered as the owners of the Notes for the purpose of receiving payments and for all other purposes. Consequently, neither the Company, the Trustee nor any agent of the Company or the Trustee has or will have any responsibility or liability for:

	(1)		any aspect of DTC’s records or any participant’s or indirect participant’s records relating to or payments made on account of beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any of DTC’s records or any participant’s or indirect participant’s records relating to the beneficial ownership interests in the Global Notes; or

	(2)		any other matter relating to the actions and practices of DTC or any of its participants or indirect participants.

Transfers between participants in DTC will be effected in accordance with DTC’s procedures, and will be settled in same-day funds.

DTC has advised us that its current practice, upon receipt of any payment in respect of securities such as the Notes (including principal and interest), is to credit the accounts of the relevant participants with the payment on the payment date unless DTC has reason to believe it will not receive payment on such payment date. Each relevant participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the relevant security as shown on the records of DTC. Payments by the participants and the indirect participants to the beneficial owners of Notes will be governed by standing instructions and customary practices and will be the responsibility of the participants or the indirect participants and will not be the responsibility of DTC, the Trustee or the Company. Neither the Company nor the Trustee will be liable for any delay by DTC or any of its participants in identifying the beneficial owners of the Notes, and the Company and the Trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

DTC has advised the Company that it will take any action permitted to be taken by a Holder of Notes only at the direction of one or more participants to whose account DTC has credited the interests in the Global Notes and only in respect of such portion of the aggregate principal amount of the Notes as to which such participant or participants has or have given such direction. However, if there is an Event of Default under the Notes, DTC reserves the right to exchange the Global Notes for legended Notes in certificated form, and to distribute such Notes to its participants.

Although DTC has agreed to the foregoing procedures in order to facilitate transfers of interests in the Global Notes among participants, it is under no obligation to perform such procedures, and such procedures may be discontinued or changed at any time. Neither the Company nor the Trustee nor any of their respective agents 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.

Exchange of global notes for certificated notes

A Global Note is exchangeable for Certificated Notes if:

(1)

DTC (A) notifies the Company that it is unwilling or unable to continue as depositary for the Global Notes or (B) has ceased to be a clearing agency registered under the Exchange Act and, in each case, a successor depositary is not appointed;

	(2)		the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Certificated Notes; or

	(3)		there has occurred and is continuing an Event of Default with respect to the Notes.

In addition, beneficial interests in a Global Note may be exchanged for Certificated Notes upon prior written notice given to the Trustee by or on behalf of DTC in accordance with the Indenture. In all cases, Certificated Notes delivered in exchange for any Global Note or beneficial interests in Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures).

Exchange of certificated notes for global notes

Certificated Notes may not be exchanged for beneficial interests in any Global Note unless the transferor first delivers to the Trustee a written certificate (in the form provided in the Indenture) to the effect that such transfer will comply with the appropriate transfer restrictions applicable to such Notes.

Same day settlement and payment

The Company will make payments in respect of the Notes represented by the Global Notes (including principal, premium, if any, interest and additional interest, if any) by wire transfer of immediately available funds to the accounts specified by the Global Note Holder. The Company will make all payments of principal, interest, premium and additional interest, if any, with respect to Certificated Notes by wire transfer of immediately available funds to the accounts specified by the Holders of the Certificated Notes or, if no such account is specified, by mailing a check to each such Holder’s registered address. The Notes represented by the Global Notes are expected to be eligible to trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in such Notes will, therefore, be required by DTC to be settled in immediately available funds. The Company expects that secondary trading in any Certificated Notes will also be settled in immediately available funds.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a participant will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a Business Day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised us that cash received in Euroclear or Clearstream as a result of sales of interests in a Global Note by or through a Euroclear or Clearstream participant to a Participant will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the Business Day for Euroclear or Clearstream following DTC’s settlement date.

Change of control

Upon the occurrence of any of the following events (each a “Change of Control”), each Holder shall have the right to require that the Company repurchase such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date):

	(1)		any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act), other than one or more Permitted Holders, is or becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act, except that for purposes of this clause (1) such person shall be deemed to have “beneficial ownership” of all shares that any such person has the right to acquire, whether such right is exercisable immediately or only after the passage of time), directly or indirectly, of more than 50% of the total voting power of the Voting Stock of the Company or Sirius Satellite Radio Inc. (for the purposes of this clause (1), such other person shall be deemed to beneficially own any Voting Stock of a Person held by any other Person (the “parent entity”), if such other person is the beneficial owner (as defined above in this clause (1)), directly or indirectly, of more than 50% of the voting power of the Voting Stock of such parent entity);

	(2)		the first day on which a majority of the members of the Board of Directors of the Company or Sirius Satellite Radio Inc. are not Continuing Directors, other than in connection with the Merger;

	(3)		the adoption of a plan relating to the liquidation or dissolution of the Company or Sirius Satellite Radio Inc.; or

	(4)		the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries taken as a whole, or of Sirius Satellite Radio Inc. and its Subsidiaries taken as a whole, to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act);

Notwithstanding the foregoing, the consummation of none of the Merger, a Holdings-Company Merger, the Escrow LLC-Company Merger, a Company-Sirius Merger or a Holdings-Sirius Merger will constitute a Change of Control under the Indenture.

Within 30 days following any Change of Control, we will mail a notice to each Holder with a copy to the Trustee (the “Change of Control Offer”) stating:

(1)

that a Change of Control has occurred and that such Holder has the right to require us to purchase such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest on the relevant interest payment date);

	(2)		the circumstances and relevant facts regarding such Change of Control (including information with respect to pro forma historical income, cash flow and capitalization, in each case after giving effect to such Change of Control);

	(3)		the purchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed); and

	(4)		the instructions, as determined by us, consistent with the Indenture and the covenant described hereunder, that a Holder must follow in order to have its Notes purchased.

We will not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by us and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

We will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of the Indenture and the covenant described hereunder, we will comply with the applicable securities laws and regulations and shall not be deemed to have breached our obligations under the Indenture and the covenant described hereunder by virtue of our compliance with such securities laws or regulations.

The Change of Control purchase feature of the Notes may in certain circumstances make more difficult or discourage a sale or takeover of the Company or Sirius Satellite Radio Inc. and, thus, the removal of incumbent management. The Change of Control purchase feature is a result of negotiations between the Company and the initial purchasers. We have no present intention to, and we have no present knowledge of a present intention by Sirius Satellite Radio Inc. to, engage in a transaction involving a Change of Control, although it is possible that we or Sirius Satellite Radio Inc. could decide to do so in the future. Subject to the limitations discussed below, we or Sirius Satellite Radio Inc. could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control under the Indenture, but that could increase the amount of indebtedness outstanding at such time or otherwise affect our capital structure or credit ratings. Restrictions on our ability to Incur additional Indebtedness are affected by the covenants described under “—Certain covenants—Limitation on indebtedness”, “—Limitation on liens” and “—Limitation on sale/leaseback transactions”. Such restrictions can only be waived with the consent of the holders of a majority in principal amount of the Notes then outstanding. Except for the limitations contained in such covenants, however, the Indenture will not contain any covenants or provisions that may afford holders of the Notes protection in the event of a highly leveraged transaction.

Future indebtedness that we may Incur may contain prohibitions on the occurrence of certain events that would constitute a Change of Control or require the repurchase of such indebtedness upon a Change of Control. Moreover, the exercise by the holders of their right to require us to repurchase their Notes could cause a default under existing or future indebtedness,

even if the Change of Control itself does not, due to the financial effect of such repurchase on us. Finally, our ability to pay cash to the holders of Notes following the occurrence of a Change of Control may be limited by our then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any required repurchases.

The definition of “Change of Control” includes a disposition of all or substantially all of the assets of the Company or Sirius Satellite Radio Inc. to any Person. Although there is a limited body of case law interpreting the phrase “substantially all”, there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve a disposition of “all or substantially all” of the assets of the Company or Sirius Satellite Radio Inc. As a result, it may be unclear as to whether a Change of Control has occurred and whether a holder of Notes may require the Company to make an offer to repurchase the Notes as described above.

The provisions under the Indenture relative to our obligation to make an offer to repurchase the Notes as a result of a Change of Control may be waived or modified with the written consent of the holders of a majority in principal amount of the Notes.

Certain covenants

Changes in covenants when Notes rated investment grade

With respect to the Notes, if on any date following the date of the Indenture:

(1) the Notes are rated Baa3 or better by ▇▇▇▇▇’▇ and BBB- or better by Standard & Poor’s (or, if either such entity ceases to rate the Notes for reasons outside of the control of the Company, the equivalent investment grade credit rating from any other “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act selected by the Company as a replacement agency); and

(2) no Default or Event of Default shall have occurred and be continuing under the Indenture, then, beginning on that day, the covenants specifically listed under the following captions in this offering memorandum will no longer be applicable to the series of Notes:

(1) “—Limitation on sales of assets and subsidiary stock;”

(2) “—Limitation on restricted payments;”

(3) “—Limitation on indebtedness;”

(4) clauses (1)(A) and (3) of the covenant described under the caption “—Limitation on sale/leaseback transactions;”

(5) “—Limitation on affiliate transactions;”

(6) clause (3) of the covenant described below under the caption “—Merger and consolidation;” and

(7) “—Limitation on restrictions on distributions from restricted subsidiaries.”

There can be no assurance that the Notes will ever achieve an investment grade rating or that any such rating will be maintained.

The Indenture contains covenants including, among others, the following:

Limitation on indebtedness

(a) The Company will not, and will not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Indebtedness; provided, however, that the Company and any Subsidiary Guarantor will be entitled to Incur Indebtedness if, on the date of such Incurrence and after giving effect thereto on a pro forma basis, the Consolidated Leverage Ratio would be less than 6.00 to 1.

	(7)		Refinancing Indebtedness in respect of Indebtedness Incurred pursuant to paragraph (a) or pursuant to clause (2), (4), (5) or (6) or this clause (7); provided, however, that to the extent such Refinancing Indebtedness directly or indirectly Refinances Indebtedness of a Subsidiary Incurred pursuant to clause (6), such Refinancing Indebtedness shall be Incurred only by such Subsidiary;

	(D)		any encumbrance or restriction with respect to a Restricted Subsidiary (or any of its property or assets) imposed pursuant to an agreement entered into for the sale or disposition of all or substantially all the Capital Stock or assets of such Restricted Subsidiary (or the property or assets that are subject to such restriction) pending the closing of such sale or disposition;

Limitation on sales of assets and subsidiary stock

(a) The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Disposition unless:

	(1)		the Company or such Restricted Subsidiary receives consideration at the time of such Asset Disposition at least equal to the fair market value (including as to the value of all non-cash consideration), as determined in good faith by the Board of Directors of the Company, of the shares and assets subject to such Asset Disposition;

	(2)		at least 75% of the consideration thereof received by the Company or such Restricted Subsidiary is in the form of cash or cash equivalents;

	(3)		an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company or such Restricted Subsidiary, as the case may be

(A)

first, to the extent the Company or such Restricted Subsidiary elects (or is required by the terms of any Indebtedness), to prepay, repay, redeem or purchase Senior Indebtedness of the Company (including the Notes) or

			Indebtedness (other than any Disqualified Stock) of any Wholly Owned Subsidiary (in each case other than Indebtedness owed to the Company or an Affiliate of the Company) within one year from the later of the date of such Asset Disposition or the receipt of such Net Available Cash;

	(B)		second, to the extent of the balance of such Net Available Cash after application in accordance with clause (A), to the extent the Company or such Restricted Subsidiary elects, to acquire Additional Assets within one year from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; provided, however, that the Company shall have an additional six months to apply such Net Available Cash pursuant to this clause (B) if it shall have entered into a binding acquisition or purchase contract in respect of Additional Assets prior to the expiration of such one-year period; and

	(C)		third, to the extent of the balance of such Net Available Cash after application in accordance with clauses (A) and (B), to make an offer to the holders of the Notes (and to holders of other Senior Indebtedness of the Company designated by the Company) to purchase Notes (and such other Senior Indebtedness of the Company) pursuant to and subject to the conditions contained in the Indenture;

provided, however, that in connection with any prepayment, repayment or purchase of Indebtedness pursuant to clause (A) or (C) above, the Company or such Restricted Subsidiary shall permanently retire such Indebtedness and shall cause the related loan commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid or purchased, provided, further, that the prior proviso shall not affect the ability of the Company or such Restricted Subsidiary to Incur Indebtedness under paragraph (b) of the covenant described under “—Limitation on indebtedness”.

Notwithstanding the foregoing provisions of this covenant, the Company and the Restricted Subsidiaries will not be required to apply any Net Available Cash in accordance with this covenant except to the extent that the aggregate Net Available Cash from all Asset Dispositions which is not applied in accordance with this covenant exceeds $10 million. Pending application of Net Available Cash pursuant to this covenant, such Net Available Cash shall be invested in Temporary Cash Investments or applied to temporarily reduce revolving credit indebtedness.

For the purposes of this covenant, the following are deemed to be cash or cash equivalents:

(1)

the assumption or discharge of Indebtedness of the Company (other than obligations in respect of Disqualified Stock of the Company) or any Restricted Subsidiary or other liabilities (as shown on the most recent balance sheet (or notes thereto) of the Company or the Restricted Subsidiary) and the release of the Company or such Restricted Subsidiary from all liability on such Indebtedness or from such other liabilities in connection with such Asset Disposition (in which

			case the Company will, without further action, be deemed to have applied such deemed cash to Indebtedness in accordance with clause (3)(A) above); and

	(2)		securities received by the Company or any Restricted Subsidiary from the transferee that are converted within 30 days by the Company or such Restricted Subsidiary into cash, to the extent of cash received in that conversion.

(b) In the event of an Asset Disposition that requires the purchase of Notes (and other Senior Indebtedness of the Company) pursuant to clause (a)(3)(C) above, the Company will purchase Notes tendered pursuant to an offer by the Company for the Notes (and such other Senior Indebtedness) at a purchase price of 100% of their principal amount (or, in the event the Notes or such other Senior Indebtedness of the Company was issued with significant original issue discount, 100% of the accreted value thereof) without premium, plus accrued but unpaid interest (or, in respect of such other Senior Indebtedness of the Company, such lesser price, if any, as may be provided for by the terms of such Senior Indebtedness) in accordance with the procedures (including prorating in the event of oversubscription) set forth in the Indenture. If the aggregate purchase price of the securities tendered exceeds the Net Available Cash allotted to their purchase, the Company will select the securities to be purchased on a pro rata basis but in round denominations, which in the case of the Notes will be denominations of $1,000 principal amount or multiples thereof. The Company shall not be required to make such an offer to purchase Notes (and other Senior Indebtedness of the Company) pursuant to clause (a)(3)(C) of this covenant if the Net Available Cash available therefor is less than $5 million (which lesser amount shall be carried forward for purposes of determining whether such an offer is required with respect to the Net Available Cash from any subsequent Asset Disposition). Upon completion of such an offer to purchase, Net Available Cash will be deemed to be reduced by the aggregate amount of such offer.

	(1)		at the time of entering into such Asset Swap and immediately after giving effect to such Asset Swap, no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof;

	(2)		in the event such Asset Swap involves the transfer by the Company or any Restricted Subsidiary of assets having an aggregate fair market value, as determined by the Board of Directors of the Company in good faith, in excess of $5 million, the terms of such Asset Swap have been approved by a majority of the members of the Board of Directors of the Company; and

	(3)		in the event such Asset Swap involves the transfer by the Company or any Restricted Subsidiary of assets having an aggregate fair market value, as determined by the Board of Directors of the Company in good faith, in excess of $20 million, the Company has received a written opinion from an Independent Qualified Party that such Asset Swap is fair to the Company or such Restricted Subsidiary, as the case may be, from a financial point of view.

(d) The Company will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to the Indenture and this covenant. To the extent that the provisions of any securities laws or regulations conflict with provisions of this covenant, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Indenture and this covenant by virtue of its compliance with such securities laws or regulations.

Limitation on affiliate transactions

(a) The Company will not, and will not permit any Restricted Subsidiary to, enter into or permit to exist any transaction (including the purchase, sale, lease or exchange of any property, employee compensation arrangements or the rendering of any service) with, or for the benefit of, any Affiliate of the Company (an “Affiliate Transaction”) unless:

	(1)		the terms of the Affiliate Transaction are no less favorable to the Company or such Restricted Subsidiary than those that could be obtained at the time of the Affiliate Transaction in arm’s-length dealings with a Person who is not an Affiliate;

	(2)		if such Affiliate Transaction involves an amount in excess of $5 million, the terms of the Affiliate Transaction are set forth in writing and a majority of the directors of the Company who have no direct financial interest with respect to such Affiliate Transaction (other than as a stockholder of the Company, Holdings or Sirius Satellite Radio Inc.) have determined in good faith that the criteria set forth in clause (1) are satisfied and have approved the relevant Affiliate Transaction as evidenced by a resolution of the Board of Directors; and

	(3)		if such Affiliate Transaction involves an amount in excess of $20 million, the Board of Directors of the Company shall also have received a written opinion from an Independent Qualified Party to the effect that such Affiliate Transaction is fair, from a financial standpoint, to the Company and its Restricted Subsidiaries or is not less favorable to the Company and its Restricted Subsidiaries than could reasonably be expected to be obtained at the time in an arm’s-length transaction with a Person who was not an Affiliate or is fair from a financial point of view.

(b) The provisions of the preceding paragraph (a) will not prohibit:

	(1)		any Investment (other than a Permitted Investment) or other Restricted Payment, in each case permitted to be made pursuant to (but only to the extent included in the calculation of the amount of Restricted Payments made pursuant to paragraph (a)(3) of the covenant described under “—Limitation on restricted payments”;

	(2)		any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment arrangements, stock options and stock ownership or other employee benefit plans approved by the Board of Directors of the Company or Sirius Satellite Radio Inc. or entered into in the ordinary course of business;

	(3)		to the extent permitted by applicable law, loans or advances to employees in the ordinary course of business in accordance with the past practices of the Company or its Restricted Subsidiaries, but in any event not to exceed $2 million in the aggregate outstanding at any one time;

	(4)		the payment of reasonable and customary fees to, and indemnity provided on behalf of, directors of the Company and its Restricted Subsidiaries who are not employees of the Company or its Restricted Subsidiaries;

	(5)		any transaction with the Company, a Restricted Subsidiary or joint venture or similar entity which would constitute an Affiliate Transaction solely because the Company or a Restricted Subsidiary owns an equity interest in or otherwise controls such Restricted Subsidiary, joint venture or similar entity;

	(6)		the issuance or sale of any Capital Stock (other than Disqualified Stock) of the Company to Affiliates of the Company and the granting of registration and other customary rights in connection therewith;

	(7)		any agreement as in effect on the Issue Date and described in this offering memorandum, as these agreements may be amended, modified, supplemented, extended or renewed from time to time (so long as any amendment, modification, supplement, extension or renewal is not less favorable in any material respect to the Company or the Restricted Subsidiaries) and the transactions evidenced thereby;

	(8)		any transaction by the Company or any Restricted Subsidiary with an Affiliate related to the purchase, sale or distribution of XM radios, subscription to XM services or other products or services in the ordinary course of business including any such transaction with an automotive manufacturer or similar business partner, which has been approved by a majority of the members of the Board of Directors of the Company who have no direct financial interest with respect to such Affiliate Transaction (other than as a stockholder of the Company, Holdings or Sirius Satellite Radio Inc.);

	(9)		a Holdings-Company Merger or a Company-Sirius Merger; and

	(10)		any transaction between the Company and a Restricted Subsidiary or between Restricted Subsidiaries.

Limitation on line of business

The Company will not, and will not permit any Restricted Subsidiary, to engage in any business other than a Related Business.

Limitation on the sale or issuance of capital stock of restricted subsidiaries

The Company

	(1)		will not, and will not permit any Restricted Subsidiary to, sell, lease, transfer or otherwise dispose of any Capital Stock of any Restricted Subsidiary to any Person (other than the Company or a Wholly Owned Subsidiary), and

	(2)		will not permit any Restricted Subsidiary to issue any of its Capital Stock (other than, if necessary, shares of its Capital Stock constituting directors’ or other legally required qualifying shares) to any Person (other than to the Company or a Wholly Owned Subsidiary),

unless

	(A)		immediately after giving effect to such issuance, sale or other disposition, neither the Company nor any of its Subsidiaries own any Capital Stock of such Restricted Subsidiary;

	(B)		such issuance, sale or other disposition is treated as an Asset Disposition and immediately after giving effect to such issuance, sale or other disposition, such Restricted Subsidiary would continue to be a Restricted Subsidiary; or

	(C)		immediately after giving effect to such issuance, sale or other disposition, such Restricted Subsidiary would no longer constitute a Restricted Subsidiary and any Investment in such Person remaining after giving effect thereto is treated as a new Investment by the Company and such Investment would be permitted to be made under the covenant described under “—Limitation on restricted payments” if made on the date of such issuance, sale or other disposition.

For purposes of this covenant, the creation of a Lien on any Capital Stock of a Restricted Subsidiary to secure Indebtedness of the Company or any of its Restricted Subsidiaries will not be deemed to be a violation of this covenant; provided, however, that any sale or other disposition by the secured party of such Capital Stock following foreclosure of its Lien will be subject to this covenant.

Limitation on liens

The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, Incur or permit to exist any Lien (the “Initial Lien”) of any nature whatsoever on any of its properties (including Capital Stock of a Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, securing any Indebtedness, other than Permitted Liens, without effectively providing that the Notes shall be secured equally and ratably with (or prior to) the obligations so secured for so long as such obligations are so secured.

Any Lien created for the benefit of the Holders of the Notes pursuant to the preceding sentence shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien.

Limitation on sale/leaseback transactions

The Company will not, and will not permit any Restricted Subsidiary to, enter into any Sale/Leaseback Transaction with respect to any property unless:

	(1)		the Company or such Restricted Subsidiary would be entitled to (A) Incur Indebtedness in an amount equal to the Attributable Debt with respect to such Sale/Leaseback Transaction pursuant to the covenant described under “—Limitation on indebtedness” and (B) create a Lien on such property securing such Attributable Debt without equally and ratably securing the Notes pursuant to the covenant described under “—Limitation on liens”;

	(2)		the net proceeds received by the Company or any Restricted Subsidiary in connection with such Sale/Leaseback Transaction are at least equal to the fair market value (as determined by the Board of Directors of the Company) of such property; and

	(3)		the Company applies the proceeds of such transaction in compliance with the covenant described under “—Limitation on sales of assets and subsidiary stock”.

Merger and consolidation

The Company will not consolidate with or merge with or into, or convey, transfer, lease, assign or otherwise dispose of, in one transaction or a series of transactions, directly or indirectly, all or substantially all its assets to, any Person, unless:

	(1)		the resulting, surviving or transferee Person (the “Successor Company”) shall be a Person organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and the Successor Company (if not the Company) shall expressly assume, by an indenture supplemental thereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the Company under the Notes and the Indenture;

	(2)		immediately after giving pro forma effect to such transaction (and treating any Indebtedness which becomes an obligation of the Successor Company or any Subsidiary as a result of such transaction as having been Incurred by such Successor Company or such Subsidiary at the time of such transaction), no Default shall have occurred and be continuing;

	(3)		immediately after giving pro forma effect to such transaction, the Successor Company would have a Consolidated Leverage Ratio equal to or better than the Company’s Consolidated Leverage Ratio immediately prior to the transaction; and

	(4)		the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with the Indenture.

provided, however, that clause (3) will not be applicable to (A) a Restricted Subsidiary consolidating with, merging into or transferring all or part of its properties and assets to the

Company (so long as no Capital Stock of the Company is distributed to any Person) or (B) the Company merging with an Affiliate of the Company solely for the purpose and with the sole effect of reincorporating the Company in another jurisdiction. In addition, the Company will not, directly or indirectly, lease all or substantially all of the properties and assets of it and its Restricted Subsidiaries taken as a whole, in one or more related transactions, to any other Person.

This “Merger and consolidation” covenant will not apply to a consolidation, merger, sale, assignment, transfer, conveyance or other disposition of properties or assets between or among the Company and any of its Restricted Subsidiaries or pursuant to the Merger or the Escrow LLC-Company Merger. This “Merger and consolidation” covenant will apply to a Holdings-Company Merger or a Company-Sirius Merger, except that for purposes of compliance with the first paragraph of this “Merger and consolidation” covenant, clause (3) shall be replaced with the following: (3) immediately after giving pro forma effect to such transaction, either (A) the Successor Company would have a Senior Secured Leverage Ratio and a Senior Unsecured Leverage Ratio equal to or better than the Company’s Senior Secured Leverage Ratio and Senior Unsecured Leverage Ratio, respectively, immediately prior to the transaction or (B) the Successor Company would be permitted to incur at least $1.00 of additional Indebtedness pursuant to paragraph (a) of the covenant described above under the caption “—Limitation on Indebtedness”.

For purposes of this covenant, the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company.

The Successor Company will be the successor to the Company and shall succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture, and the predecessor Company, except in the case of a lease, shall be released from the obligation to pay the principal of and interest on the Notes.

Future Subsidiary Guarantors

The Company shall cause any Person that becomes a Material Subsidiary of the Company at any time on or after the Issue Date to execute and deliver a supplemental indenture, duly executed on behalf of such Material Subsidiary by an Officer thereof, to the Trustee reasonably promptly after such event.

The obligations of each Subsidiary Guarantor will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under the Indenture, result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law.

SEC Reports

Whether or not the Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, Holdings will file with the SEC (subject to the next sentence) and provide the Trustee and noteholders with such annual and other reports as are specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation subject to such Sections, such reports to be so filed and provided at the times specified for the filings of such reports under such Sections and containing all the information, audit reports and exhibits required for such reports. If at any time, Holdings is not subject to the periodic reporting requirements of the Exchange Act for any reason, the Company or Holdings will nevertheless continue filing the reports specified in the preceding sentence with the SEC within the time periods required unless the SEC will not accept such a filing. Holdings agrees that it will not take any action for the purpose of causing the SEC not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept such filings for any reason, the Company or Holdings will post the reports specified in the preceding sentence on its website within the time periods that would apply if Holdings were required to file those reports with the SEC.

If the combined operations of the Parent Guarantor and its subsidiaries, excluding the operations of the Company and its Restricted Subsidiaries and excluding cash and cash equivalents, would, if held by a single Unrestricted Subsidiary of the Company, constitute a Significant Subsidiary of the Company, then the quarterly and annual financial information required by the preceding paragraphs will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Company and the Company’s Restricted Subsidiaries separate from the financial condition and results of operations of the Parent Guarantor and its other Subsidiaries; provided however, that the requirements of this paragraph shall not apply if the Company files with the SEC the reports referred to in the immediately preceding paragraph, and any such report contains the information described in this paragraph.

In addition, Holdings shall furnish to noteholders, prospective investors, broker-dealers and securities analysts, upon their request, any information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Notes are not freely transferable under the Securities Act.

Following a Company-Holdings Merger, a Holdings-Sirius Merger or a Company-Sirius Merger, the obligations of Holdings under this covenant shall be assumed by the Company or Sirius, as the case may be.

Defaults

Each of the following is an Event of Default:

	(1)		a default in the payment of interest on the Notes when due, continued for 30 days;

	(2)		a default in the payment of principal of any Note when due at its Stated Maturity, upon optional redemption, upon required purchase, upon declaration of acceleration or otherwise;

	(3)		the failure by the Company to comply with its obligations under the covenant described under “—Certain covenants—Merger and consolidation” above;

	(4)		the failure by the Company to comply for 30 days after notice with any of its obligations in the covenants described above under “Change of control” (other than a failure to purchase Notes) or under “—Certain covenants” under “—Limitation on indebtedness”, “—Limitation on restricted payments”, “—Limitation on restrictions on distributions from restricted subsidiaries”, “—Limitation on sales of assets and subsidiary stock” (other than a failure to purchase Notes), “—Limitation on affiliate transactions”, “—Limitation on the sale or issuance of capital stock of restricted subsidiaries”, or “—Limitation on liens”, or “—SEC reports”;

	(5)		the failure by the Company to comply for 60 days after notice with its other agreements contained in the Indenture (other than a failure to give notice described in clause (4) above);

	(6)		Indebtedness of the Company or any Significant Subsidiary (other than with respect to the Notes) is not paid within any applicable grace period after final maturity or is accelerated by the holders thereof because of a default and the total amount of such Indebtedness unpaid or accelerated exceeds $25 million (the “cross acceleration provision”);

	(7)		certain events of bankruptcy, insolvency or reorganization of the Company or any Significant Subsidiary (the “bankruptcy provisions”);

	(8)		any final, nonappealable judgment or decree for the payment of money which, when taken together with all other final, nonappealable judgments or decrees for the payment of money, causes the aggregate amount of such judgments or decrees entered against the Company or any Significant Subsidiary to exceed $25 million (net of any amounts with respect to which a reputable and creditworthy insurance company has acknowledged liability in writing), remains outstanding for a period of 60 consecutive days following such judgment and is not discharged, waived or stayed (the “judgment default provision”); or

	(9)		any Subsidiary Guarantee of a Significant Subsidiary ceases to be in full force and effect (except as contemplated by the terms of the Indenture) or is declared null and void in a judicial proceeding or any Subsidiary Guarantor that is a Significant Subsidiary denies or disaffirms its obligations under the Indenture or its Subsidiary Guarantee.

However, a default under clauses (4) and (5) will not constitute an Event of Default until the Trustee or the holders of 25% in principal amount of the outstanding Notes notify the Company of the default and the Company does not cure such default within the time specified after receipt of such notice.

If an Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in principal amount of the outstanding Notes may declare the principal of and accrued but unpaid

interest, if any, on all the Notes to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. In the event of a declaration of acceleration of the Notes because an Event of Default described in clause (6) under “Defaults” with respect to other Senior Indebtedness has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically annulled if the event of default or payment default triggering such Event of Default pursuant to clause (6) shall be remedied or cured by the Company or a Restricted Subsidiary of the Company or waived by the holders of the relevant Indebtedness within 20 days after the declaration of acceleration with respect thereto and if (1) the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Defaults or Events of Default, except nonpayment of principal, premium or interest on the Notes that became due solely because of the acceleration of the Notes, have been cured or waived. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company occurs and is continuing, the principal of and interest on all the Notes will ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holders of the Notes. Under certain circumstances, the holders of a majority in principal amount of the outstanding Notes may waive all past defaults and rescind any such acceleration with respect to the Notes and its consequences.

Subject to the provisions of the Indenture relating to the duties of the Trustee, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the holders of the Notes unless such holders have offered to the Trustee indemnity or security satisfactory to it against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no holder of a Note may pursue any remedy with respect to the Indenture or the Notes unless:

	(1)		such holder has previously given the Trustee notice that an Event of Default is continuing;

	(2)		holders of at least 25% in principal amount of the outstanding Notes have requested the Trustee to pursue the remedy;

	(3)		such holders have offered the Trustee security or indemnity satisfactory to it against any loss, liability or expense;

	(4)		the Trustee has not complied with such request within 60 days after the receipt thereof and the offer of security or indemnity; and

	(5)		holders of a majority in principal amount of the outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period.

Subject to certain restrictions, the holders of a majority in principal amount of the outstanding Notes are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. If an Event of Default occurs (and is not cured), the Trustee will be required, in the exercise of its power, to use the degree of care of a prudent man in the conduct of his own

affairs. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other holder of a Note or that would involve the Trustee in personal liability. Subject to such provisions, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request of any Holder of Notes, unless such Holder shall have offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense and then only to the extent required by the terms of the Indenture.

If a Default occurs, is continuing and is known to the Trustee, the Trustee must mail to each holder of the Notes notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of or interest on any Note, the Trustee may withhold notice if and so long as a committee of its Responsible Officers in good faith determines that withholding notice is not opposed to the interest of the holders of the Notes. In addition, we are required to deliver to the Trustee, within 120 days after the end of each fiscal year, a certificate indicating whether the signers thereof know of any Default that occurred during the previous year. We are required to deliver to the Trustee, within 30 days after the occurrence thereof, written notice of any event which would constitute certain Defaults, their status and what action we are taking or propose to take in respect thereof.

Amendments and waivers

Subject to certain exceptions, the Indenture, the Notes and the Guarantees may be amended with the consent of the holders of a majority in principal amount of the Notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the Notes) and any past default or compliance with any provisions may also be waived with the consent of the holders of a majority in principal amount of the Notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the Notes). However, without the consent of each holder of an outstanding Note affected thereby, an amendment or waiver may not, among other things:

	(1)		reduce the amount of Notes whose holders must consent to an amendment;

	(2)		reduce the rate of or extend the time for payment of interest on any Note;

	(3)		reduce the principal of or change the Stated Maturity of any Note;

	(4)		reduce the amount payable upon the redemption of any Note or change the time at which any Note may be redeemed as described under “—Optional redemption” above;

	(5)		make any Note payable in money other than that stated in the Note;

	(6)		impair the right of any holder of the Notes to receive payment of principal of and interest on such holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such holder’s Notes;

	(7)		release any Guarantor from its Guarantee under the Indenture except in accordance with the Indenture;

	(8)		make any change in the amendment provisions which require each holder’s consent or in the waiver provisions; or

	(9)		make any change in the ranking or priority of any Note that would adversely affect the Noteholders.

Notwithstanding the preceding, without the consent of any holder of the Notes, the Company, the Guarantors and the Trustee may amend the Indenture:

	(1)		to cure any ambiguity, omission, defect or inconsistency;

	(2)		to provide for the assumption by a successor corporation of the obligations of the Company under the Indenture;

	(3)		to provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code);

	(4)		to add Guarantees with respect to the Notes, including any subsidiary guarantees, or to secure the Notes;

	(5)		to add to the covenants of the Company or any of its Restricted Subsidiaries for the benefit of the holders of the Notes or to surrender any right or power conferred upon the Company or any of its Restricted Subsidiaries;

	(6)		to make any change that does not adversely affect the rights of any holder of the Notes;

	(7)		to comply with any requirement of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act;

	(8)		add Guarantees with respect to the Notes or release a Subsidiary Guarantor upon its designation as an Unrestricted Subsidiary; provided, however, that the designation is in accord with the applicable provisions of the Indenture;

	(9)		release a Subsidiary Guarantor from its obligations under its Subsidiary Guarantee or the Indenture in accordance with the applicable provisions of the Indenture;

	(10)		conform the text of the Indenture, the Notes or the Subsidiary Guarantees to any provision of this “Description of Notes”;

	(11)		to make any amendment to the provisions of the Indenture relating to the transfer and legending of Notes; provided, however, that (a) compliance with the Indenture as so amended would not result in Notes being transferred in violation of the Securities Act or any other applicable securities law and (b) such amendment does not materially and adversely affect the rights of Holders to transfer Notes; or

(12)

provide for the issuance of exchange securities which shall have terms substantially identical in all respects to the Notes (except that the transfer restrictions contained in the Notes shall be modified or eliminated as appropriate) and which shall be treated, together with any outstanding Notes, as a single class of securities.

The consent of the holders of the Notes is not necessary under the Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment.

After an amendment under the Indenture becomes effective, we are required to mail to holders of the Notes a notice briefly describing such amendment. However, the failure to give such notice to all holders of the Notes, or any defect therein, will not impair or affect the validity of the amendment.

Neither the Company nor any Affiliate of the Company may, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture or the Notes unless such consideration is offered to all Holders and is paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement.

Transfer

The Notes will be issued in registered form and will be transferable only upon the surrender of the Notes being transferred for registration of transfer. We may require payment of a sum sufficient to cover any tax, assessment or other governmental charge payable in connection with certain transfers and exchanges.

Satisfaction and discharge

When we (1) deliver to the Trustee all outstanding Notes for cancellation or (2) all outstanding Notes have become due and payable or will become so within one year, whether at maturity or on a redemption date as a result of the mailing of notice of redemption, and, in the case of clause (2), we or a Subsidiary Guarantor irrevocably deposit with the Trustee funds sufficient to pay at maturity or upon redemption all outstanding Notes, including interest thereon to maturity or such redemption date, and if in either case we pay all other sums payable under the Indenture by us, then the Indenture shall, subject to certain exceptions, cease to be of further effect.

Defeasance

At any time, we may terminate all our obligations under the Notes and the Indenture (“legal defeasance”), except for certain obligations, including those respecting the defeasance trust and obligations to register the transfer or exchange of the Notes, to replace mutilated, destroyed, lost or stolen Notes and to maintain a registrar and paying agent in respect of the Notes. If we exercise our legal defeasance option, the Guarantees in effect at such time will terminate.

In addition, at any time we may terminate our obligations under “—Change of control” and under the covenants described under “—Certain covenants” (other than the covenant described under "—Merger and consolidation”), the operation of the cross acceleration provision, the bankruptcy provisions with respect to Significant Subsidiaries, the judgment default provision and the Subsidiary Guarantee provision described under “—Defaults” above and the limitations contained in clause (3) of the first paragraph under “—Certain covenants—Merger and consolidation” above (“covenant defeasance”).

We may exercise our legal defeasance option notwithstanding our prior exercise of our covenant defeasance option. If we exercise our legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default with respect thereto. If we exercise our covenant defeasance option, payment of the Notes may not be accelerated because of an Event of Default specified in clause (4), (6), (7) (with respect only to Significant Subsidiaries) or (8) under "—Defaults” above or because of the failure of the Company to comply with clause (3) of the first paragraph under “—Certain covenants—Merger and consolidation” above.

In order to exercise either of our defeasance options, we or a Guarantor must irrevocably deposit in trust (the “defeasance trust”) with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Notes to redemption or maturity, as the case may be, and must comply with certain other conditions, including delivery to the Trustee of an Opinion of Counsel (subject to customary exceptions and exclusions) to the effect that holders of the Notes will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred (and, in the case of legal defeasance only, such Opinion of Counsel must be based on a ruling of the Internal Revenue Service or other change in applicable Federal income tax law).

Concerning the Trustee

The Bank of New York Mellon is to be the Trustee under the Indenture. We have appointed The Bank of New York Mellon as Registrar and Paying Agent with regard to the Notes.

The Indenture contains certain limitations on the rights of the Trustee, should it become a creditor of the Company, to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions; provided, however, if it acquires any conflicting interest it must either eliminate such conflict within 90 days, apply to the SEC for permission to continue or resign.

No personal liability of directors, officers, employees and stockholders

No director, officer, employee, incorporator or stockholder of the Company, any of its Restricted Subsidiaries or any Guarantor will have any liability for any obligations of the Company, any of its Restricted Subsidiaries or any Guarantor under the Notes or the Indenture or for any claim based on, in respect of, or by reason of such obligations or their creation. Each

Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver and release may not be effective to waive liabilities under the U.S. Federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

Governing law

The Indenture and the Notes will be governed by, and construed in accordance with, the laws of the State of New York.

Certain definitions

“Additional Assets” means:

	(1)		any property, plant, license or equipment used in a Related Business;

	(2)		the Capital Stock of a Person that becomes a Restricted Subsidiary as a result of the acquisition of such Capital Stock by the Company or another Restricted Subsidiary; or

	(3)		Capital Stock constituting a minority interest in any Person that at such time is a Restricted Subsidiary;

provided, however, that any such Restricted Subsidiary described in clause (2) or (3) above is primarily engaged in a Related Business.

“Affiliate” of any specified Person means any other Person, directly or indirectly, controlling or controlled by or under direct or indirect common control with such specified Person. For the purposes of this definition, “control” when used with respect to any Person means the power to direct the management and policies of such Person, directly or indirectly, whether through the ownership of voting securities, by contract or otherwise; and the terms “controlling” and “controlled” have meanings correlative to the foregoing. For purposes of the covenants described under “—Certain covenants—Limitation on restricted payments”, “—Certain covenants—Limitation on affiliate transactions” and “—Certain covenants—Limitation on sales of assets and subsidiary stock” only, “Affiliate” shall also mean any beneficial owner of Capital Stock representing 10% or more of the total voting power of the Voting Stock (on a fully diluted basis) of the Company (excluding any Person permitted to report such ownership on Schedule 13G under the Exchange Act) or of rights or warrants to purchase such Capital Stock (whether or not currently exercisable) and any Person who would be an Affiliate of any such beneficial owner pursuant to the first sentence hereof.

“Asset Disposition” means any sale, lease (other than an operating lease entered into in the ordinary course of business), transfer or other disposition (or series of related sales, leases, transfers or dispositions) by the Company or any Restricted Subsidiary, including any disposition by means of a merger, consolidation or similar transaction (each referred to for the purposes of this definition as a “disposition”), of:

	(1)		any shares of Capital Stock of a Restricted Subsidiary (other than directors’ qualifying shares or shares required by applicable law to be held by a Person other than the Company or a Restricted Subsidiary);

	(2)		all or substantially all the assets of any division or line of business of the Company or any Restricted Subsidiary; or

	(3)		any other assets of the Company or any Restricted Subsidiary outside of the ordinary course of business of the Company or such Restricted Subsidiary

(other than, in the case of clauses (1), (2) and (3) above,
