(j) Filings and Recordings.

- 6 -

Satellite at the end of the Basic Term to a commercially viable orbit, (v) the conclusion that Buyer’s Transponders are not “limited use property” and that it is reasonable to expect that Buyer’s Transponders will be useful or usable in a commercially feasible manner at the end of the Basic Term by Owner Participant or a Person other than Lessee or an Affiliate thereof, (vi) an estimate of the expected fair market sales value of Buyer’s Transponders on the EBO Date and at the end of the Basic Term (which estimates shall be equal to or less than the EBO Amount and the exercise price of the Lessee’s option to purchase Buyer’s Transponders at the end of the Basic Term, respectively), (vii) the conclusion that Lessee is no more likely to exercise any of its purchase options as the result of the covenant in Section 13(c) of the Lease than it would have been if such covenant was not included, and (viii) the conclusion that there is nothing in the terms of the Operative Documents or XM Agreements (or any other circumstance) that would create any compulsion for Lessee to exercise any of its purchase options if the fair market sales value of Buyer’s Transponders is less than the applicable purchase option price. Indenture Trustee shall have received evidence satisfactory to it (in the form of a copy of the relevant sections of the Appraisal) as to Independent Appraiser’s estimate of the fair market sales value of Buyer’s Transponders as of the anticipated Closing Date.

This Section 5.02(b) shall not be deemed to permit prepayment of the Notes except as permitted by the Indenture.

Otherwise, in connection with Owner Participant’s appointment of a successor Owner Trustee, the expenses incurred in connection therewith and any incremental increase in fees payable to the successor Owner Trustee shall be paid by Owner Participant.

Holdings and Lessee shall, from time to time, discuss with Owner Participant the inclusion or deletion of any one or more Persons as Competitors or Competitor Related Parties, and Holdings, Lessee and Owner Participant shall resolve all such issues in good faith. If (i) Holdings, Lessee and Owner Participant agree that one or more Persons should be added to or deleted from the Competitor List or (ii) Holdings or Lessee shall have made a public filing with the SEC specifically identifying Persons as principal competitors that are not then listed on the Competitor List, Holdings and Lessee shall (in the case of clause (i)) or may (in the case of clause (ii)) update such list by adding or deleting such other Persons as applicable (provided that (1) no such Person may be added to the Competitor List pursuant to clause (ii) prior to the thirty-first (31^st) day following such public filing and (2) Holdings or Lessee may not add the names of more than three Persons per annum as a result of having listed such names in a public filing with the SEC; and provided, further, that any disagreement about the addition of any such Person shall be resolved promptly by an analyst with expertise in the satellite radio business mutually agreeable to Holdings, Lessee and Owner Participant), and promptly deliver each such updated Competitor List to Owner Participant. The Persons on the most recently delivered Competitor List shall be deemed to be the only Competitors or Competitor Related Parties, as the case may be, solely for purposes of the Operative Documents.

If (i) Holdings or Lessee shall have notified Owner Participant of any merger, acquisition, investment or other similar event or condition with respect to Owner Participant that it has a reasonable basis to believe has caused Owner Participant to become a Competitor OP, (ii) Holdings or Lessee shall have notified Owner Participant that it has a reasonable basis to believe a Competitor Information Violation has occurred or (iii) Owner Participant has Actual Knowledge that any such event or condition has caused it to become a Competitor OP or that a Competitor Information Violation has occurred, Owner Participant will, as promptly as practicable, deliver to Holdings and Lessee an Officer’s Certificate of Owner Participant confirming or denying that Owner Participant has become a Competitor OP and whether a Competitor Information Violation has occurred; provided that any such Officer’s Certificate shall be held in strict confidence and shall not be disclosed by Holdings or Lessee to any other Person or used by Holdings or Lessee other than in connection with considering whether to exercise its rights under Section 10.01(b) or (c). Notwithstanding the foregoing, if Owner Participant has not concluded whether there is sufficient control (within the meaning

- 29 -

contemplated by the definition of “Affiliate” herein) for it to be an Affiliate of a Competitor, such Officer’s Certificate of Owner Participant may state that fact and, solely for purposes of this Participation Agreement, such statement shall be treated as if it were an admission that Owner Participant is an Affiliate of a Competitor.

This Section 5.02(f) and related definitions are included solely for the benefit of Lessee and Owner Participant, and may be amended by them (in a writing signed by them) without approval of the Note Purchasers or any other parties hereto; provided that no such amendment shall alter the general scope of such provisions.

Upon payment in full of any indemnity pursuant to this Section 6.01, Lessee shall, without need for any further action and to the extent permitted by Applicable Law, be subrogated to any right of such Indemnitee in respect of the matter against which such indemnity has been paid to the extent of such payment. Each Indemnitee will give such further assurances or agreements and cooperate with Lessee to permit Lessee to pursue such claims, if any, to the extent reasonably requested by Lessee and at Lessee’s expense.

(b) Without limitation of the foregoing, Lessee shall pay on an After-Tax Basis (except to the extent such amounts are payable by Owner Participant as part of its Commitment, or by Owner Participant pursuant to Section 9.01 (unless specified otherwise in such Section 9.01)) all the out-of-pocket costs and expenses (including, without limitation, reasonable legal fees and expenses) reasonably incurred by Owner Participant, Owner Trustee or Indenture Trustee in connection with (A) the entering into or giving or withholding of any future amendments, supplements, waivers or consents (whether or not they become effective) with respect to any Operative Document or XM Agreements (other than those that are made at the request of such Indemnitee (unless made pursuant to Section 11.05) or are made in connection with the transfer of Owner Participant’s interest in accordance with Article XII hereof (unless made while any Lease Event of Default is continuing)), (B) the taking of any action under the Lease or the Indenture at the request of Lessee (including any sale or effort to sell under Section 8 of the Lease) or as a result of a Lease Default or Event of Default (including any exercise of remedies under Section 16 of the Lease), (C) any Event of Loss, or any actual or proposed redemption, prepayment or refinancing of Notes (including, without limitation, any prepayment, proposed refinancing and refinancing contemplated by Section 11.01, whether or

(c) If Lessee or any Indemnitee has Actual Knowledge of any action, suit, proceeding or claim hereby indemnified against under this Section 6.01 or any action, suit, proceeding or claim seeking incidental or consequential damages against Indemnitee with respect to Buyer’s Transponders subject to the Lease whether or not indemnified against under this Section 6.01, it shall give prompt written notice thereof to the other and Lessee (or its insurer(s)) may assume the defense thereof, and, at such Indemnitee’s request, shall assume the defense thereof with counsel reasonably acceptable to such Indemnitee. Such Indemnitee shall fully cooperate (at Lessee’s expense) with Lessee and its insurer(s) in all ways reasonably requested by Lessee in said defense by Lessee. In any such action, any Indemnitee shall have the right to employ separate counsel in such action and participate therein, subject to the preceding sentence, but the fees and expenses of such counsel shall be at the expense of such Indemnitee, unless (i) the employment of such counsel at Lessee’s expense has been specifically authorized in writing by Lessee, (ii) such Indemnitee determines in good faith that the representation of such Indemnitee and any other named party to such action by the same counsel would be inappropriate under the applicable standards of professional conduct due to actual or potential conflicting interests between them or (iii) such action involves an act that involves or is alleged to involve criminal activity undertaken in compliance with or as contemplated by the Operative Documents or XM Agreements or involves the risk of criminal penalties. Lessee shall not be liable for any settlement of any action, suit, proceeding or claim effected without its written consent and no Indemnitee will agree to any such settlement without the prior written consent of Lessee (which shall not be unreasonably withheld).

(d) Notwithstanding the provisions of the immediately preceding paragraph, the omission by any Indemnitee to notify Lessee of any Expense shall not relieve Lessee from any liability which it may have hereunder in respect of any such Expense or other Expense; provided, however, that nothing herein contained shall prevent Lessee from bringing a subsequent action against such Indemnitee for damage suffered by Lessee as a result of such omission.

(e) In the case of any Expense indemnified by the Lessee hereunder which is covered by a policy of insurance maintained by Lessee pursuant to Section 9 of the Lease, at Lessee’s expense, each Indemnitee agrees to cooperate (at the Lessee’s expense) with the reasonable requests of the insurers in the exercise of their rights to investigate, defend or compromise such Expense as may be required to retain the benefits of such insurance with respect to such Expense.

(f) If an Indemnitee is not a party to this Participation Agreement, Lessee may require such Indemnitee to agree in writing to the terms of this Section 6.01 and Section 13.07 prior to making any payment to such Indemnitee under this Section 6.01.

(g) If, by reason of any Expense payment made to or for the account of an Indemnitee by Lessee pursuant to this Section 6.01, such Indemnitee concurrently or subsequently realizes a tax deduction or credit not previously taken into account in computing such payment, such Indemnitee shall promptly pay to Lessee (but only if Lessee shall have made

XM-4 Participation Agreement

- 34 -

all payments then due and owing to such Indemnitee under the Operative Documents), an amount equal to the sum of (i) the actual reduction in Taxes realized by such Indemnitee which is attributable to such deduction or credit plus (ii) the actual reduction in Taxes realized by such Indemnitee as a result of any payment made by such Indemnitee pursuant to this sentence; provided, that such Indemnitee shall not be obligated to make any payment to Lessee pursuant to this sentence if and for so long as a Payment Default, Bankruptcy Default or any Event of Default shall have occurred and be continuing, but shall promptly make such payment once all such Events of Default shall no longer be continuing; and provided further, however, that such Indemnitee shall not be obligated to make any payment pursuant to this Section 6.01 to the extent that the amount calculated pursuant to (i) above would exceed (x) the amount of all prior payments received by such Indemnitee from Lessee pursuant to this Section 6.01 with respect to such Expense (determined without regard to any amount paid in respect of Taxes required to be paid by such Indemnitee in respect of the receipt or accrual of such amounts) less (y) the portion of all prior payments computed pursuant to (i) above paid by such Indemnitee to Lessee hereunder. Any Taxes that are imposed on any Indemnitee as a result of a disallowance or reduction of any tax benefit taken into account in the prior sentence shall be treated as a Tax for which Lessee is obligated to indemnify such Indemnitee pursuant to the provisions of Article VII hereof without regard to Section 7.02 (other than subsections (f) and (g) thereof) or Section 7.04 thereof.

(h) In the event of a conflict between the provisions of Article 8 of the Purchase Agreement or Article 6 of the Service Agreement and the provisions of this Participation Agreement, the provisions of this Participation Agreement shall prevail.

(i) Except as expressly provided in this Participation Agreement or in any other Operative Document, Lessee shall not be liable to any Indemnitee for incidental or consequential damages suffered by such Indemnitee; provided, however, that the foregoing shall not be construed to limit recovery by any Indemnitee of any costs, expenses or liabilities incurred by such Indemnitee as a result of any third party claim against such Indemnitee based on events occurring and/or conditions existing (or alleged to have occurred or be existing) any time prior to the expiration or earlier termination of the Lease, except to the extent incurred by such Indemnitee as a result of affirmative actions of such Indemnitee to market or otherwise utilize any Buyer’s Transponders; provided, however, that nothing in this exception shall modify or limit Lessor’s remedies under Section 16 of the Lease, and Lessee’s obligations under this Section 6.01 shall survive for so long as Lessor or the Indenture Trustee shall be entitled to exercise remedies under Section 16 of the Lease.

(j) With respect to any amount which Lessee is requested by an Indemnitee to pay by reason of this Article VI, Indemnitee shall, if requested by Lessee and prior to any payment, submit such additional information to Lessee as Lessee may reasonably request properly to substantiate the requested payment.

SECTION 6.02. Exceptions. Notwithstanding anything contained in Section 6.01, Lessee shall not be required to indemnify, protect, defend and hold harmless any Indemnitee pursuant to Section 6.01 in respect of any Expense of such Indemnitee:

(a) For any Taxes, loss of Tax benefits or costs or expenses of any administrative or judicial proceedings contesting any Taxes or loss of Tax benefits, whether or not Lessee is required to indemnify therefor pursuant to Article VII or the Tax Indemnification

(n) Taxes payable by a successor, assignee or transferee (including any transfer by merger, consolidation, liquidation, reorganization or otherwise by operation of law) of any Indemnitee, or a Related Indemnitee of such successor, assignee or transferee, to the extent of the excess (measured on the date of such succession, transfer or assignment) of the amount of Taxes that would have been indemnified by Lessee under Section 7.01 but for this clause (n) over the amount of Taxes that would have been imposed on the predecessor, transferor or assignor Indemnitee and indemnified by Lessee under this Article VII had there not been such succession, transfer or assignment; provided, that this clause (n) shall not apply (i) with respect to any transfer made at the request of Lessee or occurring in connection with the exercise of remedies while an Event of Default is continuing, and (ii) to any amounts necessary to make any payment required to be made under the Operative Documents on an After-Tax Basis; and

(o) any Tax imposed on any Noteholder or a Related Indemnitee with respect to a voluntary sale, transfer, assignment or other voluntary disposition by such Noteholder or any Related Indemnitee, or an involuntary disposition by such Noteholder or any Related Indemnitee (other than such an involuntary disposition that results from a default by Lessee, Owner Participant or Lessor), of any interest in a Note, any other Operative Document or any any other Indemnitee; provided, however that this exception shall not apply in the event that such sale, transfer, assignment or other disposition shall occur as the result of any acts pursuant to Sections 7, 8, 12, 16 or 19 of the Lease.

SECTION 7.03. Calculation of Indemnity Payments. If any Indemnitee subsequently realizes a reduction in Taxes payable by such Indemnitee that are not indemnified against by Lessee pursuant to Section 7.01 (a “Tax Benefit”) by reason of the payment or accrual of any Tax Indemnified against pursuant to Section 7.01 or by reason of payment of an amount, which amount was reimbursed to such Indemnitee by Lessee on an After-Tax Basis pursuant to a provision specifically requiring the payment of such amount on an After-Tax Basis (other than pursuant to any provision of the Tax Indemnification Agreement), which Tax Benefit had not previously been taken into account in computing such payment, such Indemnitee shall pay Lessee when such Tax Benefit is actually realized (but not before Lessee shall have made all payments and indemnification theretofore due to such Indemnitee pursuant to the Operative Documents) an amount equal to the lesser of (a) the sum of (i) an amount equal to such Tax Benefit, plus (ii) an amount equal to any other Tax Benefit actually realized by such Indemnitee as the result of the payment or accrual by such Indemnitee of the amount payable pursuant to this sentence, and (b) the amount of such payment and any other payment by Lessee to such Indemnitee with respect to the Tax or other amount that gave rise to such Tax Benefit, reduced by other amounts previously paid by such Indemnitee to Lessee with respect to the Tax Benefits resulting from such Tax or other amount pursuant to this Article VII; provided, however, that, notwithstanding the foregoing portions of this sentence, such Indemnitee shall not be obligated to

- 40 -

make any payment to Lessee pursuant to this sentence if and for so long as an Event of Default shall have occurred and be continuing, but shall promptly make such payment once all Events of Default shall no longer be continuing. Any Taxes that are imposed on any Indemnitee as a result of a disallowance or reduction of any Tax Benefit taken into account in the prior sentence shall be treated as a Tax for which Lessee is obligated to indemnify such Indemnitee pursuant to the provisions of Section 7.01 hereof without regard to Section 7.02 (other than subsections (f), (g) and (i) thereof).

SECTION 7.04. Contest. (a) If a claim shall be made against any Indemnitee for any Tax in excess of $50,000 for which Lessee would be obligated to indemnify pursuant to Section 7.01, such Indemnitee shall promptly notify Lessee after such Indemnitee becomes aware of such action and in any event within thirty (30) days after receipt by such Indemnitee of a written claim (but failure to notify Lessee within such thirty (30) day period shall not impair such Indemnitee’s right to indemnification under Section 7.01 except to the extent that Lessee’s rights to contest such claim shall have been materially impaired by such failure) and shall, to the extent permitted by Applicable Law, not pay the claim before the earlier of (i) thirty (30) days after giving Lessee notice and (ii) receipt of Lessee’s response. Subject to the conditions specified in this Section 7.04, if Lessee shall so request within the period referred to in the foregoing sentence, such Indemnitee shall, at Lessee’s expense reimbursed to such Indemnitee on an After-Tax Basis, contest the imposition, validity or applicability of such Tax. The ultimate control over the conduct of such contest (including the right to forgo any and all administrative appeals, proceedings, hearings and conferences in respect of such claim and the right to select the forum for such contest and determine whether any such contest shall be by (i) resisting payment of such Tax, (ii) paying such Tax under protest or (iii) paying such Tax and seeking a refund thereof) shall remain with such Indemnitee; provided, however, that such Indemnitee shall keep Lessee or its counsel reasonably informed as to the progress thereof, consult with Lessee within a reasonable period before any significant action with respect thereto is taken or omitted and consider in good faith any suggestions made by Lessee or its counsel; provided further that, subject to Indemnitee’s waiver rights described in Section 7.04(b) hereof, and provided that all conditions set forth in this Section 7.04 for the continuation of a contest shall then be satisfied, no such proceedings or litigation shall be settled or otherwise compromised without the prior written consent of Lessee. If such Indemnitee so elects, such contest shall be conducted by Lessee in the name of such Indemnitee (subject to the preceding proviso) and in no event shall such Indemnitee be required or Lessee be permitted to contest or to continue to contest, as the case may be, the imposition of any Tax for which Lessee is obligated to indemnify pursuant to Section 7.01 unless (A) Lessee shall have agreed to pay such Indemnitee on demand and shall have paid as so demanded all reasonable costs and expenses that such Indemnitee may incur in connection with contesting such claim (including, without limitation, all costs, expenses, losses, reasonable legal and accounting fees and disbursements) on an After-Tax Basis, (B) Owner Participant shall have determined in good faith that the action to be taken will not, and the Indenture Trustee, at the direction of a Majority Interest of Noteholders, shall not have notified Lessee that it has determined in its good faith discretion that the action to be taken will, result in (x) any material risk of a Lien (including without limitation, a Lien superior to the Indenture Trustee’s Lien under the Indenture) on, or of sale, forfeiture or loss of Buyer’s Transponders or any part thereof or any interest therein (except if Lessee shall have made provision to protect the interests of Owner Participant, Indenture Trustee and the Noteholders in a manner satisfactory to such Persons) or (y) the possible imposition of criminal or other similar

- 41 -

sanctions on any Indemnitee, (C) if such contest shall be conducted in a manner requiring the payment of the claim, Lessee shall have advanced on an interest-free basis an amount equal to the amount of such claim which such Indemnitee shall have elected to pay and Lessee shall have indemnified the Indemnitee in a manner satisfactory to the Indemnitee, for any adverse tax consequences from the receipt, or interest-free nature, of such advance, and (D) if an Event of Default or Bankruptcy Default shall have occurred and be continuing, Lessee shall have posted adequate security securing payment of the Tax subject to the contest and the expenses of the contest in a manner reasonably acceptable to such Indemnitee.

(b) An Indemnitee may at any time elect to settle or compromise any proposed claim or contest or decline to take any action or any further action with respect to a proposed claim or contest; provided, however, that if Lessee has properly requested such action pursuant to this Article VII and has satisfied all conditions set forth in Section 7.04(a) for the continuation of a contest, such Indemnitee shall notify Lessee that it waives its right to any indemnity payment by Lessee that would otherwise be payable by Lessee pursuant to this Article VII in respect of such claim. An election by an Indemnitee to settle or compromise any proposed claim or contest or decline to take any action or take any further action with respect to a proposed claim or contest for any given taxable period shall not affect the rights and obligations of any other Indemnitee with respect to such proposed claim. An election by an Indemnitee to settle or compromise any proposed claim or contest or decline to take any action with respect to a proposed claim or contest (under circumstances where Lessee shall have properly requested action and satisfied all conditions for the continuation of a contest set forth in Section 7.04(a)) shall not affect the rights and obligations of such Indemnitee and Lessee hereunder in respect of any other taxable period or any other taxing authority except to the extent such election not to contest materially impairs as a legal or practical matter the ability of Lessee or an Indemnitee to contest any Tax with respect to such other taxable period or such other taxing authority for which such Indemnitee is indemnified pursuant to Section 7.01. Upon any such election by an Indemnitee, if Lessee shall have advanced an amount to an Indemnitee pursuant to clause (C) of Section 7.04(a), such Indemnitee shall repay the advance to Lessee, plus interest on such advance from the date of the making of such advance by Lessee to the day next preceding the day of repayment of such advance by such Indemnitee calculated at the applicable rate of the tax authority with respect to the claims to which the advance related; such repayment shall be made upon the occurrence of the earlier of (x) final adjudication of such contest (including a settlement thereof) and (y) such time as such Indemnitee shall elect to discontinue the contest as above provided; provided, however, notwithstanding the foregoing, such Indemnitee shall not be obligated to make any repayment to Lessee pursuant to this sentence for so long as any Payment Default, Bankruptcy Default or Event of Default shall have occurred and be continuing but shall promptly make such payment once all Payment Defaults, Bankruptcy Defaults and Events of Default shall no longer be continuing.

SECTION 7.05. Reports. If any report, return or statement is required to be filed with respect to any Tax which is subject to indemnification under this Article VII, Lessee shall promptly notify the appropriate Indemnitee of such requirement and shall timely file the same, except for any such report, return or statement which an Indemnitee has notified Lessee that such Indemnitee intends to file or which requires information related to the Indemnitee not reasonably available to Lessee which the Indemnitee chooses to withhold from Lessee; provided, however, prior to the filing by any Indemnitee of any report, return or statement in respect of

XM-4 Participation Agreement

- 42 -

which an amount greater than $10,000 is required to be paid by Lessee, such Indemnitee shall notify Lessee that such report, return or statement and such Tax is due and such notification shall be within a reasonable amount of time to enable Lessee to contest such Tax, and, with respect to any report, return or statement being filed by Lessee, the Indemnitee shall at Lessee’s expense be required to provide Lessee on a timely basis with any information reasonably requested, provided, further, that, without prejudice to any other rights Lessee may have in connection therewith (including, without limitation, any claim for damages for a failure to give the notice or reasonably requested information pursuant to this Section 7.05), the failure to provide any such notice or reasonably requested information shall not affect Lessee’s obligations hereunder to any Indemnitee unless such failure shall materially impair a contest of such Tax. Lessee shall either file such report, return or statement so as to show the ownership of Buyer’s Transponders in Owner Trustee and send a copy of such report, return or statement to the Indemnitee or, where not so permitted, promptly notify the Indemnitee of such requirement and prepare and deliver such report, return or statement to the Indemnitee in a manner satisfactory to the Indemnitee within a reasonable time prior to the time such report, return or statement is to be filed. Notwithstanding the foregoing provisions of this Section 7.05, no Indemnitee shall have any obligation to provide Lessee a copy of or access to any Tax report, return or statement required to be filed by such Indemnitee, including any consolidated, combined or unitary tax return, report or statement that includes such Indemnitee.

SECTION 7.06. Payment. (a) Unless otherwise requested by the appropriate Indemnitee, Lessee shall pay any Tax for which it is liable pursuant to this Article VII directly to the appropriate taxing authority when due and, if so otherwise requested, shall pay such appropriate Indemnitee within fifteen (15) days after demand, in immediately available funds, any amount due such Indemnitee pursuant to Section 7.01 with respect to such Tax or such payment, but not prior to the later of (i) the date such Tax is payable and (ii) final adjudication (including settlement consented to by Lessee) in the case of a contest pursuant to Section 7.04. Any such demand shall specify in reasonable detail the payment and the facts upon which the right to payment is based. Each Indemnitee shall promptly forward to Lessee any notice, bill or advice received by it concerning any Tax for which such Indemnitee claims indemnification hereunder. Within thirty (30) days after the date of each payment by Lessee of any Tax, Lessee shall furnish the appropriate Indemnitee with the original or a certified copy of a receipt for Lessee’s payment of such Tax or such other evidence of payment of such Tax as is reasonably acceptable to such Indemnitee. Lessee shall also furnish promptly upon request such data within its or an Affiliate’s control as any Indemnitee may require to enable such Indemnitee to comply with the requirements of any taxing jurisdiction applicable as a result of the Overall Transaction.

(b) Lessee agrees that it shall have no right to inspect the books, records, tax returns or any other document of such Indemnitee or any Affiliate thereof in order to verify the basis or accuracy of the calculations made pursuant to this Article VII: provided, however, within ten (10) days following Lessee’s receipt of any notice or demand involving calculations to be made pursuant to this Article VII, Lessee may request that the correctness of such calculations be verified (but such verification shall be limited to calculations and shall not extend to any interpretation of the scope of any indemnity provision or the existence of a liability hereunder) by one of the four largest United States public accounting firms selected by the relevant Indemnitee and approved by Lessee, which approval will not be unreasonably withheld, and such Indemnitee shall deliver to Lessee a certificate of a senior officer together with a statement from

XM-4 Participation Agreement

- 43 -

such public accounting firm confirming that the calculations set forth in or supporting the amount set forth in such notice or demand to which such request relates have been verified as above provided and that the calculations are accurate and in conformity with the provisions of this Article VII. The assumptions, the method of calculation and the other information revealed or made available to such accounting firm shall be kept confidential and shall not be revealed by it to any other Person. The fees and expenses of such accounting firm shall be paid by Lessee, provided that the Indemnitee (or, if the Indemnitee is the Owner Trustee, the Owner Participant) shall pay such fees and expenses if such verification results in an adjustment in Lessee’s favor of five (5%) percent or more of the amount originally determined to be due by such Indemnitee.

SECTION 7.07. Consolidated or Combined Return. In the case of any Tax for which an Indemnitee claims indemnification hereunder that is reported on a consolidated or combined basis by such Indemnitee, the rules applicable to the consolidated or combined return of the Indemnitee shall be taken into account in computing the amount of any indemnity or payment by or to Lessee under this Article VII in respect of such Tax.

SECTION 7.08. Withholding Tax on Rent. If any Tax that is required to be deducted and withheld from payments of Base Rent, Stipulated Loss Value, the EBO Amount or any amount determined by reference to Stipulated Loss Value or the Fair Market Sales Value of Buyer’s Transponders that is not subject to indemnification by Lessee under Section 7.01 by reason of any exclusion from indemnification described in Section 7.02 applicable to Owner Participant or any Related Indemnitee, Lessee shall, to the extent necessary, increase the amount payable by it so that, after such deduction and withholding, the amount paid to the Indenture Trustee is an amount sufficient to pay the net amounts (after deduction for any Taxes imposed on Indenture Trustee or the Noteholders that are not indemnified against by Lessee pursuant to Section 7.01), if any, then payable to the Noteholders pursuant to the Notes or the Indenture. To the extent Lessee is required to make any additional payment pursuant to the preceding sentence, Owner Participant shall within five (5) Business Days of notice from Lessee of such payment accompanied by evidence of such payment reasonably acceptable to Owner Participant reimburse Lessee for such amount paid by Lessee, plus interest for the period from the date paid by Lessee to the date of payment at the Prime Rate.

SECTION 7.09. Cooperation. Within a reasonable time and in all events within thirty (30) days (or such shorter time period necessary to permit compliance with deadlines imposed by any relevant taxing authority) after the Lessee receives from an Indemnitee a written request for information reasonably available to Lessee or Holdings and reasonably determined by such Indemnitee (as the case may be) as necessary to enable such Indemnitee to fulfill its Tax filing, Tax audit or other Tax obligations or to contest Taxes imposed upon it (whether or not such Tax is indemnified under any of the Operative Documents), the Lessee shall, at the Lessee’s expense, provide such information to the requesting party.

ARTICLE VIII.

SECTION 8.01. Effect of Other Indemnities.

SECTION 8.03. No Guaranties, etc. Nothing herein or in the Tax Indemnification Agreement shall be construed as a guaranty by Lessee of any residual or other value in Buyer’s Transponders or the useful life of Buyer’s Transponders or constitute a guaranty by Lessee of payment of principal of or interest on the Notes or any other amount payable under the Indenture.

If the transactions contemplated by this Participation Agreement to be consummated on the Closing Date are not consummated, Lessee shall pay when due all Transaction Costs accrued to such failed Closing Date, the payment of which is otherwise the obligation of Owner Trustee pursuant to the first sentence of this Section 9.01(a); provided, however, that if such transactions shall not be consummated by reason of a breach by Owner Trustee or Owner Participant of its obligations hereunder or under any other Operative Document or XM Agreement to which such Person is or will be a party, Lessee shall not be obligated to pay the Transaction Costs incurred by such Person.

(b) To the extent the Owner Participant’s Commitment plus the Transaction Costs to be paid by Owner Participant pursuant to this Participation Agreement would exceed the Equity Cap, the Owner Participant shall pay the Transaction Costs designated in clause (i) (to the extent of legal fees and disbursements for special counsel of Owner Participant), clause (ii), clause (iii) (to the extent of such costs of counsel for Owner Participant, Owner Trustee and Indenture Trustee), clause (iv), clause (vi), and clause (vii) of the definition thereof and such other Transaction Costs as the Owner Participant and Lessee mutually agree, provided that the aggregate Transaction Costs paid by Owner Participant, together with the Commitment of Owner Participant, shall not exceed the Equity Cap, and any Transaction Costs not paid by the Owner Participant will be paid by Lessee.

(d) As a condition to Lessee’s right to purchase the Beneficial Interest under Section 10.01 or Section 11.07(h), on the date of purchase, Lessee shall have provided to Indenture Trustee and Owner Trustee an opinion of counsel for Lessee, dated the date of purchase, which, subject to usual or customary exceptions, shall be to the effect that, upon consummation of such purchase, (i) each of this Participation Agreement, the Trust Agreement, the Lease and, in the case of Holdings, the Guaranty Agreement constitutes the legal, valid and binding obligation of Lessee or, in the case of the Guaranty Agreement, Holdings, enforceable against Lessee or Holdings, as applicable, in accordance with its respective terms except as the same may be limited by applicable Bankruptcy Laws affecting the rights of creditors generally and by general principles of equity, and except as limited by applicable laws that may affect the remedies provided for in or other provisions of the Lease, which laws, however, do not in the opinion of such counsel render unenforceable the obligations to pay Rent thereunder and (ii) the validity and perfection of the Lien of the Indenture is not affected in any adverse respect by such purchase or the consummation thereof. In the event Lessee is unable to provide such opinion, concurrently with the purchase of the Beneficial Interest, Lessee shall, subject to Sections 10.03 and 10.06 assume the obligations of Owner Trustee under the Notes and under the Indenture in accordance with, subject to the conditions of and with the effect provided in, Section 2.11 of the Indenture, and Lessee shall thereafter have the right to terminate the Trust Agreement. It is acknowledged and agreed by the parties hereto that Lessee’s right and obligation to assume the Notes in connection with a purchase of the Beneficial Interest under Section 10.01 shall only arise in the event that the Noteholders have (or been deemed to have) rejected the corresponding Repurchase Offer in accordance with the applicable provisions of Section 10.06.

(e) Owner Trustee and Lessee acknowledge and agree that the former Owner Participant which shall have transferred the Beneficial Interest to Lessee under Section 10.01 or Section 11.07(h) (the “Transferor”) is entitled to all Excepted Payments, whether payable prior to the date of purchase or that become payable on or after the date of purchase, that are attributable to events or circumstances occurring prior to the date of purchase under Section 10.01 or Section 11.07(h). Owner Trustee hereby agrees that upon receipt by it of any

amounts in respect of such Excepted Payments that is owed to Transferor pursuant to this paragraph, it will forthwith pay over such amounts to the Transferor.

(f) From and after any purchase of the Beneficial Interest pursuant to this under Section 10.01 or Section 11.07(h), (i) the Transferor shall be released from its liability hereunder and under the other Operative Documents and XM Agreements to which it is or will be a party in respect of obligations to be performed on or after the date of such purchase and (ii) Lessee shall be deemed “Owner Participant” for all purposes of the Operative Documents and each reference herein to Owner Participant shall thereafter be deemed a reference to Lessee for all purposes (except that the rights of the Owner Participant (including without limitation, its rights under Article VI or VII and under the Tax Indemnity Agreement) attributable to acts or events prior to such transfer shall survive).

SECTION 10.03. Assumption of Notes. In order to (a) elect to exercise its right to assume or exchange the Notes pursuant to Section 19(c) of the Lease or (b) effect, subject to Section 10.06, the assumption or exchange of Notes required by Section 10.02(d) or Section 11.07(h), Lessee shall irrevocably notify Owner Trustee, Owner Participant and Indenture Trustee in writing thereof at the same time Lessee provides notice to Lessor under the Lease. Each party hereto which is not a party to the Lease hereby consents to Lessee’s right to assume or exchange the Notes pursuant to such Sections, subject to the terms and conditions therein, and, subject to Section 10.06, agrees to perform the actions, if any, contemplated by that Section to be performed by it (in each case with the expenses, fees and costs of such actions to be paid by Lessee).

(a) In connection with a purchase by Lessee of the Beneficial Interest pursuant to Section 10.01(b), (c), (e) or (f) Lessee may elect, by giving notice of such election in its notice given pursuant to Section 10.02 hereto, to either

(i) pay the entire Beneficial Interest Purchase Price in immediately available funds as provided in Section 10.01(b), (c), (e) or (f) hereof; or

(ii) satisfy the obligation to pay such Beneficial Interest Purchase Price on the date of the purchase by paying a portion thereof in immediately available funds (such portion being at least equal to, but not exceeding, accrued Rents) and by issuing to Owner Participant a promissory note substantially in the form of Exhibit Q hereto made by Lessee in a principal amount equal to the balance of such Beneficial Interest Purchase Price (the “Deferred Payment Note”), having the terms set forth below as applicable.

(b) If Lessee makes the election set forth in Section 10.04(a)(ii), then on the date of the purchase,

(i) Lessee shall maintain in place an Effective Equity Wrap or enter into alternative credit support arrangements reasonably acceptable to Owner Participant in an amount equal to the sum of the principal of the Deferred Payment Note and an amount equal to the interest that will accrue under such Deferred Payment Note from the date of issuance until the maturity date thereof, assuming that the Prime Rate remains at the Prime Rate on the date such Deferred Payment Note is issued and that there will be

- 50 -

no prepayments under such Deferred Payment Note, which Effective Equity Wrap or credit support may be reduced to reflect any principal amounts prepaid under the Deferred Payment Note.

(ii) the principal amount of the Deferred Payment Note shall be due in a lump sum six (6) months (if Lessee shall have exercised its option to purchase pursuant to Section 10.01(b), (e) or (f)) or nine (9) months (if Lessee shall have exercised its option to purchase pursuant to Section 10.01(c)) after such purchase, with interest at the Prime Rate payable at maturity, prepayable, subject to Section 10.06, at any time without penalty. Any amounts not paid when due under the Deferred Payment Note shall bear interest at the Overdue Rate.

In connection with any renewal or refinancing of such secured credit facilities, XM shall use commercially reasonable efforts to ensure that the amended or new financing arrangements entered into by XM (i) do not include a security interest in the Beneficial Interest at any time that a Deferred Payment Note is outstanding and (ii) permit XM to grant to the holder of the Deferred Payment Note the security interest in the Beneficial Interest contemplated by Exhibit P, and, if so permitted, from and after such time the references in Exhibit P to the grant by XM of a security interest in the Beneficial Interest shall apply.

(d) If Lessee notifies Owner Participant that it is seeking to identify a third party to purchase the Beneficial Interest from Lessee and/or perform Lessee’s obligations under the Deferred Payment Note prior to the maturity date thereof, Owner Participant shall, at Lessee’s request, cooperate in all reasonable respects with Lessee’s efforts to sell such Beneficial Interest (including providing information to such third party regarding the reasons for sale of the Beneficial Interest by Owner Participant, but not including any marketing efforts), and Lessee shall reimburse Owner Participant for all reasonable out-of-pocket expenses incurred in connection with such cooperation.

SECTION 10.05. Credit Support for Buyout Amount.

If Lessee advises Lessor and Owner Participant prior to delivery of the Final Notice that it intends to purchase Buyer’s Transponders, Lessee, Lessor and Owner Participant shall work together in good faith to determine the types of credit support and/or collateral arrangements reasonably acceptable to Owner Participant. Lessee agrees not to provide cash collateral to the provider of such credit support except as contemplated by Alternative 3 of Schedule V hereto. For the avoidance of doubt, Lessee shall not be required to comply with this Section 10.05 if Lessee elects to purchase Buyer’s Transponders pursuant to Section 19(a)(ii) of the Lease.

SECTION 10.06. Offer to Repurchase in Connection with Purchase of Beneficial Interest.

(a) Each of the following shall be a “Repurchase Offer Event”: (i) the purchase of the Beneficial Interest on the EBO Date under Section 10.01(a) (an “EBO BI Purchase”); (ii) the purchase of the Beneficial Interest for cash (and not by the issuance of a Deferred Payment Note) under Sections 10.01(b), (c), (d), (e), (f) or (g) (a “BI Cash Purchase”); (iii) following the purchase of the Beneficial Interest by the issuance of a Deferred Payment Note under Sections 10.01(b), (c), (e) or (f) the payment by Lessee of the principal amount (other than any mandatory prepayments, as permitted by the Subordination terms in Exhibit P) due under the Deferred Payment Note (a “BI Deferred Purchase”); or (iv) the purchase of the Beneficial Interest that is an Equity Wrap Purchase under Section 10.01(g) (a “BI Equity Wrap Purchase”). Notwithstanding any provisions of the Operative Documents to the contrary, but subject to the last sentence of this Section 10.06(a), the sole right of Lessor based on a Repurchase Offer Event in respect of which Lessee has made a Repurchase Offer as set forth below shall be its rights under this Section 10.06, and a Repurchase Offer Event shall not constitute a Default or an Event of Default under this Agreement, the Lease or any other Operative Document so long as Lessee makes a Repurchase Offer in accordance herewith and complies with its obligations under this Section 10.06 with respect to consummating any transaction resulting from the acceptance of such offer. Nothing in this Section 10.06 shall modify any obligation of Lessee under Section 10.01, or any remedies based thereon.

(b) If Lessee expects a Repurchase Offer Event to occur, Lessee will make an offer (a “Repurchase Offer”) to Lessor, to effect the purchase of Buyer’s Transponders for the purchase price specified and in accordance with whichever of paragraphs (c), (d), (e) or (f) of this Section 10.06 as is applicable. If Lessor does not accept the Repurchase Offer within the period specified in whichever of paragraphs (c), (d), (e) or (f) of this Section 10.06 as is applicable, such offer shall be deemed to have been rejected, and Lessee shall have no further obligations to Lessor under this Section 10.06 with respect to such Repurchase Offer or such Repurchase Offer Event.

(c) If Lessee intends to make an EBO BI Purchase, Lessee shall make a binding and irrevocable Repurchase Offer by written notice to Lessor at least forty-five (45) days and not more than one-hundred eighty (180) days prior to the EBO Date.

Such purchase of Buyer’s Transponders shall occur on the EBO Date, concurrently with the EBO BI Purchase (in each case, if the Repurchase Offer is accepted by Lessor and becomes non-contingent, neither the EBO BI Purchase nor Repurchase Offer may close unless the other closes concurrently); provided that, if such Repurchase Offer has been accepted in accordance with this clause (c), Lessee’s failure to consummate such Repurchase Offer shall be a Lease Event of Default pursuant to Section 15(l) of the Lease.

(l) Owner Participant shall have received from Independent Tax Counsel an opinion to the effect that the Refinanced Notes should be “qualified nonrecourse indebtedness” within the meaning of Section 1.861-10T of the Regulations; provided, however, that in the event Owner Participant shall not have received such an opinion, at the request of Lessee, Owner Participant and Lessee shall negotiate in good faith regarding an indemnity payment calculated pursuant to Section 3.04(a) of the Tax Indemnification Agreement in lieu of such opinion (it being understood that Owner Participant shall be under no obligation to agree to any such indemnity);

(m) (A) Owner Participant shall not have delivered to Lessee, within fifteen (15) Business Days of Lessee’s written notice to Lessor of Lessee’s intent to exercise the

foregoing refinancing right (which written notice shall not be deemed delivered unless it shall have been accompanied by a term sheet setting forth the expected material terms of such refinancing), an Adverse Accounting Effect Certificate certifying that such refinancing would result in an Adverse Accounting Effect under clause (i) of the definition thereof and that the Refinancing Notes shall as a result of a change in the existing applicable accounting standards after the date hereof or a change in the interpretation of the existing applicable accounting standards by an accepted accounting standards body (such as the FASB), be subject to an accounting treatment to which the Refinanced Notes were not subject or (B) if Owner Participant shall so deliver an Adverse Accounting Effect Certificate, Lessee shall have delivered to Owner Participant a written offer to purchase all of Owner Participant’s right, title and interest in the Beneficial Interest immediately preceding the closing of such refinancing for an amount equal to the Beneficial Interest Purchase Price as provided in Section 10.01(f) (it being understood and agreed that the condition to the refinancing of the Notes specified in this clause (m) shall be satisfied in the event Lessee so delivers such written offer to purchase the Beneficial Interest), determined as of the Casualty Payment Date immediately preceding the closing of such refinancing; provided, however, that for purposes of clause (A) of this paragraph, if the final terms of such refinancing would have an accounting treatment different in any material respect from those set forth in the term sheet delivered by Lessee pursuant to such clause (A), Owner Participant shall have an additional ten (10) Business Days to deliver an Adverse Accounting Effect Certificate after receiving a revised term sheet or other documents (which may be in draft form) reflecting such revised terms for purposes of clause (A);

(n) the terms and conditions of such Refinancing Notes (except with regard to the terms described in, and to the extent permitted by, clauses (b), (f), (g) and (h) above) will, in the aggregate, be no less favorable to Owner Participant than the terms and conditions applicable to the Refinanced Notes, as reasonably determined by Owner Participant; provided, however, that if the Refinanced Notes shall have been issued in a public offering, in the event that the Refinancing Notes are to be privately placed, all the terms and conditions of the Refinancing Notes (except with regard to the terms described in, and to the extent permitted by, clauses (b), (f), (g) and (h) above) will, in the aggregate, be no less favorable to Owner Participant than the market terms and conditions (except with regard to the terms described in, and to the extent permitted by, clauses (b), (f), (g) and (h) above) upon which the Refinanced Notes would have been issued on the date actually issued, had the same been issued in a similar type of private placement, as reasonably determined by Owner Participant; and

(o) all reasonable expenses (including attorney’s fees and internal costs) incurred by Owner Participant in connection with any such refinancing (whether consummated or not) will be financed as part of the refinancing, subject to clause (g) above, or paid on an After-Tax Basis by Lessee.

SECTION 11.03. Notice. Lessee shall give Owner Trustee, Owner Participant and Indenture Trustee at least forty-five (45) days prior written notice of any desired refinancing pursuant to this Article XI, which notice shall set forth to the extent practicable the proposed terms and conditions of such refinancing, including the desired date therefor. Lessee, Owner Trustee, Owner Participant and, as necessary, Indenture Trustee, shall consult thereafter on the negotiation of such terms and conditions to the end that, subject to the provisions of this Article XI, the final terms and conditions of such refinancing shall be agreed among the parties thereto in due course thereafter. Lessee will provide notice promptly to such Persons in the

XM-4 Participation Agreement

- 59 -

event that Lessee determines not to proceed with such proposed refinancing. Lessee may revoke any such notice; provided, however, that if Lessee provides notice (stating that it is a definitive notice) that such financing is to close on or about a particular date and has requested Lessor to provide notice to Indenture Trustee under Section 2.3 of the Indenture, such notice under this Section 11.03 shall become irrevocable ten (10) days prior to the closing date set forth in such notice under the Indenture.

SECTION 11.04. Rights of Parties. Notwithstanding anything to the contrary contained herein, in no event shall Owner Participant or Indenture Trustee have any obligation to initiate or structure any refinancing of Notes or to take, or to cause Owner Trustee to take, any action in connection therewith other than such as may be requested by Lessee as provided in this Article XI.

SECTION 11.05. Lease Rental Adjustments and Adjustment of Factors. To the extent required by Section 6 of the Tax Indemnification Agreement or if the Notes have been refinanced pursuant to Section 11.01 or there is a Partial Loss in respect of which Lessee has paid an Applicable Portion of Stipulated Loss Value pursuant to Section 12(c) of the Lease, then Lessor’s Cost and the Factors shall be adjusted (upwards or downwards, as the case may be, but in no event below zero) using the same methods, constraints and assumptions (as modified on account of the occurrence of any of the events referred to in this Section 11.05) used to calculate such items on the Closing Date in each case to: (1) maintain Owner Participant’s Net Economic Return through the EBO Date (as adjusted, if applicable) and through the Basic Term and (2) to the extent possible consistent with clause (1) hereof, minimize the implicit lease rate through the EBO Date (including the EBO Amount) or if such adjustments are being made after the EBO Date, the implicit lease rate through the end of the Basic Term; provided that in no event shall the EBO Amount be adjusted below the greatest of (x) 105% of the estimated fair market sales value of Buyer’s Transponders on the EBO Date, determined as of the Closing Date and set forth in the Appraisal, (y) Stipulated Loss Value (and Premium Amount, if any) of Buyer’s Transponders as of the EBO Date as recomputed pursuant to this Section 11.05, and (z) 102% of the sum of the present values as of the EBO Date (computed using an annual discount rate equal to 16.7% compounded monthly) of (i) the scheduled Base Rent payments after the EBO Date through the end of the Basic Term and (ii) the fair market sales value of Buyer’s Transponders as of the end of the Basic Term as set forth in the Appraisal. To the extent possible, all adjustments pursuant to this Section 11.05 shall be made in compliance with Section 467 of the Code and the Regulations thereunder or any judicial decision, or any Revenue Ruling, Revenue Procedure or other published IRS interpretation of general application interpreting or relating to Section 467 of the Code (for this purpose, compliance with Section 467 of the Code shall mean making such adjustments in a manner such that rent will be accounted for under Sections 1.467-1(d)(2)(iii) and 1.467-1(f)(6)(i) of the Regulations or any successor provision thereto), and, to the extent applicable, in compliance with the requirements of Rev. Proc. 2001-28, 2001-19 IRB 1156 and Sections 4.02(5), 4.07(1) and 4.07(2) of Rev. Proc. 2001-29, 2001-19, IRB 1160 (or any successor provisions) as they exist at the time of such adjustment; provided, however, that in the absence of any change to Section 467 of the Code (or the Regulations thereunder) or to the requirements of Rev. Proc. 2001-28 or Rev. Proc. 2001-29 that is effective with respect to this Lease, such compliance shall be in the same manner and to the same extent as Base Rent complied with such requirements prior to such adjustment. Any adjustment to the Pricing Assumptions resulting from the application of this Section 11.05 shall amend the existing

XM-4 Participation Agreement

- 60 -

Schedule III hereto. Notwithstanding anything to contrary contained herein, (1) all adjustments pursuant to this Section 11.05 shall provide that (x) Base Rent payable under the Lease shall be sufficient to make scheduled principal and interest payments on the Notes and (y) Stipulated Loss Value and EBO Amount (together with any Base Rent payable on the applicable payment date) shall be sufficient to redeem in full the Notes, including any Premium Amount and accrued and unpaid interest thereon and (2) no reduction in any Stipulated Loss Value shall be made for any payment pursuant to the Tax Indemnification Agreement in connection with an event subject to indemnification thereunder in excess of the amount by which the sum of the present values of the additional Federal, state and local income taxes payable by Owner Participant as a result of such event exceeds the sum of the present values of any anticipated reductions in Federal, state and local income taxes payable by Owner Participant as a result of such event, in each case computed using a reasonable discount rate acceptable to Owner Participant and Lessee (if not otherwise provided for in the Tax Indemnification Agreement) and assuming Owner Participant is subject to tax at the Effective Tax Rate or such other rate as may be provided for in the Tax Indemnification Agreement.

SECTION 11.06. Confirmation of Adjustments; Further Assurances. (a) The adjustment to any of the Factors pursuant to Section 11.05 shall be determined by Owner Participant. The Owner Participant shall provide to Lessee, Lessor and Indenture Trustee notice of such adjustment accompanied by an Officer’s Certificate of Owner Participant which Officer’s Certificate shall set forth such adjustment and which shall confirm that such adjustment was made in accordance with the provisions of Section 11.05. Such adjustment shall, subject to the following provisions of this Section 11.06, become effective as of a date not later than the next succeeding Rent Payment Date, which occurs at least fifteen (15) days after the date of such adjustment, or, if later, the date of the conclusion of the verification procedure set forth in Section 11.06(b) (in each case taking into effect the effective date of such adjustment).

(b) Within twenty (20) Business Days after receipt of an Officer’s Certificate pursuant to paragraph (a) above in respect of an adjustment pursuant to Section 11.05, if Lessee believes that such adjustment is incorrect, Lessee may request that such adjustment be verified by one of the four largest U.S. independent public accounting firms, including Owner Participant’s regular independent accounting firm, as selected by Owner Participant. In such verification process, such accounting firm shall be given access by Owner Participant to the assumptions, methods of calculation, computations, computer programs and files employed by Owner Participant in calculating such proposed adjustment and employed in the original calculation of the Factors, subject to the execution of such confidentiality agreements as Owner Participant shall reasonably request; provided that in the event such verification process requires access to the tax books and records, tax returns or other tax related documents of Owner Participant, the review may only be conducted by Owner Participant’s regular independent accounting firm with Owner Participant’s cooperation and Owner Participant shall arrange for such review to be conducted with a scope reasonably satisfactory to Lessee.

Such verification by such accounting firm shall be at the expense of Lessee unless such verified adjustment results in a readjustment in favor of Lessee that exceeds four basis points in the implicit lease rate through the EBO Date (including the EBO Amount) or if such adjustments are being made after the EBO Date, the implicit lease rate through the end of the Basic Term, in which case the fees of the accounting firm in connection with such verification shall be at the expense of Owner Participant. Such determination of the adjustment by Owner

XM-4 Participation Agreement

- 61 -

Participant, or, if so requested in accordance with this Section 11.06(b), such verified adjustment, as the case may be, shall be conclusive and binding on the parties hereto.

(c) At the time any adjustment is made pursuant to Section 11.05 or this Section 11.06, the parties hereto shall memorialize such adjustment as appropriate and shall enter into such amendments to the Operative Documents (including an amendment to Schedule III hereto and a supplement to the Lease) and do such further acts as may be reasonably required in order to effectuate such adjustments; provided that such adjustment shall become effective as provided in this Section 11.06 without regard to the date on which any such document is executed and delivered; and further provided that any amendment to Schedule III hereto, pursuant to Section 11.05 or 11.06, may be made by Owner Participant and Holdings.

SECTION 11.07. Offer to Repurchase or Refinance.

(a) Each of the following shall be an “ORR Event”: (i) the occurrence of a Change of Control if Lessee is not Investment Grade immediately following such Change of Control (an “ORR Change of Control Event”), (ii) the occurrence of an SDARS License Event if Lessee is not Investment Grade immediately following such SDARS License Event (an “ORR SDARS License Event”), (iii) the consummation of any merger or other transaction in violation of Section 13(a) of the Lease (an “ORR Merger Event”), or (iv) Lessee fails to comply with Section 13(b) of the Lease (an “ORR Covenant Event”). Notwithstanding any provisions of the Operative Documents to the contrary, the sole right of Lessor based on an ORR Event in respect of which Lessee has made an Offer to Purchase or Refinance as set forth below shall be its rights under this Section 11.07, and an ORR Event shall not constitute a Default or an Event of Default under this Agreement, the Lease or any other Operative Document so long as Lessee makes an Offer to Purchase or Refinance in accordance herewith and complies with its obligations under this Section 11.07 with respect to consummating any transaction resulting from the acceptance of such offer.

(b) Upon the occurrence of an ORR Event, Lessee will make a binding and irrevocable offer (an “Offer to Purchase or Refinance”) to Lessor to effect whichever of the following is applicable under Section 11.07(e): (1) the purchase of Buyer’s Transponders for a purchase price equal to the ORR Payment Amount (an “ORR Purchase”) or (2) the refinancing of the outstanding Notes (an “ORR Refinancing”). If Lessee is obligated to make an Offer to Purchase or Refinance, within thirty (30) days, or within such other time as Owner Participant agrees in the case of an ORR SDARS License Event under clause (i) of the definition thereof, following the ORR Event, Lessee will deliver notice to Lessor in accordance with Section 13.03, Owner Participant and Indenture Trustee stating that an ORR Event has occurred and that an Offer to Purchase or Refinance is being made pursuant to this Section 11.07. Copies of such Offer to Purchase or Refinance shall be sent concurrently by Lessee to the Noteholders.

(c) Lessor must, to the extent provided in clause (i) and (ii) below, accept such offer by written notice to Lessee given in accordance with Section 13.03 within thirty (30) days from the date the Offer to Purchase or Refinance notice is given in accordance with Section 13.03 (“ORR Acceptance Notice”); provided that, Lessor shall not accept such offer to Purchase or Refinance unless required to do so by clause (i) or (ii) below.

(i) If the ORR Event is an ORR Change of Control Event, an ORR SDARS License Event or an ORR Merger Event, Lessor must accept such offer either if

XM-4 Participation Agreement

- 62 -

the Indenture Trustee, acting at the direction of the Majority Interest of Noteholders, directs Lessor in writing within such period to accept such offer (a “Noteholder Acceptance”) or Owner Participant directs Lessor in writing within such period to accept such offer (an “OP Acceptance”). The ORR Acceptance Notice shall state whether Lessor has obtained a Noteholder Acceptance and whether Lessor has obtained an OP Acceptance prior to Lessor’s acceptance.

(ii) If the ORR Event is an ORR Covenant Event, Lessor must accept such offer if the Indenture Trustee, acting at the direction of the Majority Interest of Noteholders directs Lessor in writing within such period to accept such offer.

(d) If Lessor does not accept the Offer to Purchase or Refinance within thirty (30) days after the date the Offer to Purchase or Refinance notice is given in accordance with Section 13.03, (i) such offer shall be deemed to have been rejected, and Lessee shall have no further obligations with respect to such Offer to Purchase or Refinance or such ORR Event and (ii) if such ORR Event is an ORR Covenant Event, the violation of the covenant set forth in the Senior Notes Indenture with respect to which non-compliance in violation of Section 13(b) of the Lease led to the ORR Covenant Event shall be deemed to have been waived, and any continuing non-compliance with such covenant as a result of such violation shall no longer constitute a violation of Section 13(b) of the Lease or Default or Event of Default hereunder or thereunder (although such waiver shall not apply to any new noncompliance with such covenant or any other such covenant) or require any additional Offer to Purchase or Refinance.

(e) If Lessor accepts the Offer to Purchase or Refinance as provided above, then

(i) If the ORR Event is an ORR Change of Control Event, an ORR SDARS License Event or an ORR Merger Event, (A) if the ORR Acceptance Notice states that Lessor has not obtained an OP Acceptance prior to such acceptance, Lessee shall seek to effect an ORR Refinancing as provided below, or (B) if the ORR Acceptance Notice states that Lessor has obtained an OP Acceptance prior to such acceptance, Lessee shall, subject to Section 11.07(h), effect an ORR Purchase as provided below.

(ii) If the ORR Event is an ORR Covenant Event, Lessee shall seek to effect an ORR Refinancing as provided below.

(f) If Lessee is to seek to effect an ORR Refinancing as provided above, Lessee shall have a period of three (3) months from the date of receipt of an ORR Acceptance Notice or three (3) months (or such shorter period in which Lessee is then purchasing notes issued under the Senior Notes Indenture) from the date of the ORR Event, in the case of an ORR Change of Control Event or ORR Covenant Event (an “ORR Refinancing Period”), during which it shall use commercially reasonable efforts to complete the ORR Refinancing. Any ORR Refinancing shall be for all (but not less than all) of the Notes and shall be conducted in the same manner, and subject to the same conditions (including those set forth in Section 11.02), as an optional refinancing under Section 11.01, except that (x) the amount to be paid to the holders of the Notes shall equal 101% of the aggregate principal amount of the Notes outstanding, plus accrued and unpaid interest (if not otherwise included in the applicable payment amount), but without any Premium Amount on the Notes (the “Notes Repurchase Amount”) on the date the

XM-4 Participation Agreement

- 63 -

Notes are redeemed in connection with such refinancing, which shall be the closing date of such refinancing; (y) any such refinancing shall not constitute one of the two optional refinancings permitted by Section 11.01; and (z) Lessee shall not be obligated to complete the ORR Refinancing if the Rent Payments to be made under the Lease as adjusted for the Refinancing Notes would be greater than such payments prior to such adjustment (but in such event Lessee shall be obligated to purchase Buyer’s Transponders under Section 11.07(g)).

Subject to the limitations set forth herein and in Section 11.02, Lessee, Owner Participant, Noteholders, Owner Trustee and Indenture Trustee agree to cooperate with reasonable requests of Lessee to effect an ORR Refinancing, including redeeming the outstanding Notes under Section 2.5(a)(iv) of the Indenture, and to negotiate in good faith to conclude such additional agreements and such supplements or amendments to or consents or waivers under each of the Operative Documents as may be reasonably requested by Lessee to effect the transactions contemplated in connection with such refinancing in compliance with and subject to the terms and conditions of this Section 11.07, Section 11.01 and Section 11.02, including, without limitation, any amendment or supplement to the Indenture that may be reasonably necessary to allow the Notes to take the form of public, private institutional or commercial bank debt, and, subject to Section 11.02, will negotiate in good faith to resolve any resulting debt/equity points in a manner reasonably satisfactory to Owner Participant, Lessee and the proposed holders of any such debt.

(g) Lessee shall be obligated to purchase Buyer’s Transponders at the purchase price specified in clause (A) below if (i) Lessee does not complete the ORR Refinancing during the ORR Refinancing Period (and in such event Lessee will mail a notice (the “Unsuccessful ORR Refinancing Notice”), not later than two (2) Business Days after the last day of the ORR Refinancing Period, to Lessor to such effect, with copies sent concurrently to the Noteholders and Owner Participant), unless Owner Participant provides Lessor within thirty (30) days after receipt of such notice with funds necessary to redeem the outstanding Notes at the Notes Repurchase Amount under Section 2.5(a)(iv) of the Indenture, or (ii) Lessee is to make an ORR Purchase as provided above. Such purchase shall occur on a purchase date set by Lessee, of which written notice is provided to Lessor and Indenture Trustee (with copies to the Noteholders and Owner Participant), which date shall be no earlier than thirty (30) and no later than sixty (60) days from (x) the date of the Unsuccessful ORR Refinancing Notice, in the case of a purchase under clause (i) of this paragraph, or (y) the date Lessee becomes required to make an ORR Purchase as provided in Section 11.07(e), in the case of a purchase under clause (ii) of this paragraph; provided, however, in the case of an ORR Change of Control Event or ORR Covenant Event, such closing shall occur no later than the date that is three (3) months after the ORR Event (or such shorter period in which Lessee is then purchasing notes issued under the Senior Notes Indenture). Subject to Section 11.07(h) below, on the date of purchase, Lessee shall pay to Lessor the sum of (A) either (1) the ORR Payment Amount, in the case of an ORR Purchase that did not result from an unsuccessful refinancing, or (2) Stipulated Loss Value as of the most recent Casualty Payment Date, in the case of an ORR Purchase that resulted from an unsuccessful refinancing, per clause (i) above; (B) any Base Rent due on such date (to the extent not otherwise included in the ORR Payment Amount) and (C) any unpaid Supplemental Rent accrued or due as of such date. Upon receipt of the payments set forth in the preceding sentence, Lessor shall transfer all right, title and interest of Lessor in and to Buyer’s Transponders, as is and where is, to Lessee, free and clear of Lessor Liens and Owner Participant Liens, but

XM-4 Participation Agreement

- 64 -

otherwise without warranty, and Lessor shall execute and deliver to Lessee, at Lessee’s reasonable expense, a bill of sale or assignment and such other instruments, documents and opinions as Lessee may reasonably request to evidence the valid consummation of such transfer and shall take, at Lessee’s expense, such actions under Section 10 of the Indenture as Lessee may reasonably request.

(h) Notwithstanding the provisions of Section 11.07(g) above, if the ORR Acceptance Notice stated that there has not been a Noteholder Acceptance, Lessee’s obligation to effect the ORR Purchase shall be modified as follows. Lessee shall (at Lessee’s option), by written notice to Lessor given in accordance with Section 13.03 at least five (5) Business Days prior to the closing for the ORR Purchase (with copies sent concurrently to the Noteholders and Owner Participant), elect to (i) assume the Notes in the same manner as provided in Section 19(c) of the Lease, subject to the conditions set forth in Section 2.11 of the Indenture, or (ii) purchase the Beneficial Interest at a purchase price equal to the applicable Beneficial Interest Purchase Price or (iii) subject to satisfying the requirements of Article XII for a Transferee in connection therewith, cause a third party to purchase the Beneficial Interest at a purchase price equal to the applicable Beneficial Interest Purchase Price (but Lessee shall remain obligated to pay or cause payment of the applicable Beneficial Interest Purchase Price and to ensure that the transfer of the Beneficial Interest is consummated in accordance with the Transferee requirements of Article XII ). If Lessee elects or is required to assume the Notes, the closing for the ORR Purchase shall proceed as specified in Section 11.07(g) above except that the obligation of Lessee to pay the ORR Payment Amount to Lessor as provided therein shall be satisfied by (1) paying the applicable Beneficial Interest Purchase Price to Owner Participant and (2) such assumption of the Notes (and such assumption shall proceed in the same manner as provided in Section 19(c) of the Lease and Section 2.11 of the Indenture). If Lessee elects to purchase the Beneficial Interest, the closing for the ORR Purchase shall relate only to the purchase of such Beneficial Interest, the purchase price shall be the applicable Beneficial Interest Purchase Price, the provisions of Section 10.02 of this Participation Agreement shall apply to such transaction and Lessee shall pay the amounts referred to in clauses (B) and (C) of Section 11.07(g). If Lessee elects to cause a third party to purchase the Beneficial Interest, the closing for the ORR Purchase shall relate only to the purchase of the Beneficial Interest by such third party, and upon payment of the applicable Beneficial Interest Purchase Price to Owner Participant at such closing and Lessee’s payment of the amounts referred to in clauses (B) and (C) of Section 11.07(g), the obligation to effect the ORR Purchase shall be deemed to have been satisfied, and Lessee shall have no further obligations with respect to such Offer to Purchase or Refinance or such ORR Event. If Lessee elects to cause a third party to purchase the Beneficial Interest, the closing for the ORR Purchase shall be extended for a period of ninety (90) days to permit the Lessee to find a third party purchaser. During this ninety (90) day extension, Lessee shall use its commercially reasonable efforts to cause a third party to purchase the Beneficial Interest. If Lessee does not cause a third party to purchase the Beneficial Interest within such ninety (90) day period, Lessee shall on the first Business Day after such ninety (90) day period expires, purchase the Beneficial Interest at a purchase price equal to the applicable Beneficial Interest Purchase Price and Lessee shall pay the amounts referred to in clauses (B) and (C) of Section 11.07(g). Any sale of a Beneficial Interest under this Section 11.07(h) shall be, as is and where is, to Lessee, free and clear of Lessor Liens (provided that only Lessor, and not Owner Participant, shall be responsible for removal of Lessor Liens, and the existence of any Lessor Liens shall not impair or delay Owner Participant’s rights, including its right to receive payment under any Effective Equity Wrap) and Owner Participant Liens, but otherwise without warranty.

SECTION 11.08. Offer to Purchase Rather than Assume. If Lessee intends to purchase Buyer’s Transponders under Section 19(a)(ii), Section 19(a)(iii) or Section 7(e) (following an acceptance of Lessee’s offer to purchase Buyer’s Transponders under clause (x)(B) or (xi) of the second paragraph of Section 7(e)) of the Lease and intends as part of such purchase to assume the Notes in accordance with Section 19(c) of the Lease, Lessee shall, by written notice in accordance with Section 13.03 to Lessor and, so long as the Lien of the Indenture is in effect, Indenture Trustee not less than forty-five (45) days and not more than 180 days prior to the date on which the Notes would otherwise have been assumed in accordance with Section 19(c) of the Lease, make a binding and irrevocable offer to purchase Buyer’s Transponders for a purchase price equal to (i) with respect to a proposed purchase under Section 19(a)(ii) of the Lease, the applicable EBO Amount, (ii) with respect to a proposed purchase under Section 19(a)(iii) of the Lease, the applicable Stipulated Loss Value as of the Casualty Payment Date on which the proposed purchase would otherwise occur or (iii) with respect to a proposed purchase under Section 7(e) of the Lease, an amount equal to the sum of (w) the higher of Fair Market Sales Value or the Stipulated Loss Value as of the next Casualty Date not less than sixty (60) days following such offer, (x) all unpaid Base Rent due as of such Casualty Payment Date, (y) any unpaid Supplemental Rent accrued or due as of such Casualty Payment Date and (z) all reasonable out-of-pocket costs and expenses of the Lessor, Owner Participant, Owner Participant Guarantor and Indenture Trustee. For the avoidance of doubt, such purchase price shall be in lieu of the purchase price that would have been applicable in the absence of such an assumption. Lessor may accept such offer, by written notice to Lessee (so long as the Lien of the Indenture is in effect, with a copy of such notice to be delivered to the Indenture Trustee) given in accordance with Section 13.03 within thirty (30) days from the date notice is given in accordance with the first sentence of this Section 11.08. Lessor must, and may only, accept such offer if Indenture Trustee, at the direction of the Majority Interest of Noteholders, directs Lessor in writing to accept such offer. If Lessor accepts such offer within such period, Lessee shall purchase Buyer’s Transponders in accordance with Section 19(b) or Section 7(e), as the case may be, of the Lease (provided that the purchase price determined in accordance with Section 19 of the Lease shall be adjusted to the extent provided in this Section 11.08) and Lessee shall not have the right to assume the Notes in accordance with Section 19(c) of the Lease (or, for the avoidance of doubt, Section 2.11 of the Indenture). If Lessor does not accept such offer within such period, Lessee shall be permitted to elect to assume the Notes in accordance with Section 19(c) of the Lease (and, for the avoidance of doubt, Section 2.11 of the Indenture).

ARTICLE XII.

Transfer of Owner Participant’s Interest

SECTION 12.01. Restrictions on Transfer. Commencing on the date hereof, without the prior written consent of Lessee, for so long as the Lease shall be in effect (unless a Payment Default, Bankruptcy Default or Event of Default has occurred and is continuing), and, without the prior written consent of Indenture Trustee, for so long as the Lien of the Indenture shall be in effect, Owner Participant shall not, directly or indirectly, assign, convey or otherwise transfer (whether by consolidation, merger, sale of assets or otherwise) any of its right, title or interest in and to the Beneficial Interest, and Owner Participant shall ensure that the holders of the equity interests in Owner Participant (“OP Interests”) shall not, directly or indirectly, assign,

XM-4 Participation Agreement

- 66 -

convey or otherwise transfer (whether by consolidation, merger, sale or assets or otherwise) the OP Interests, in whole or in part, or rights to acquire the OP Interests (where transfers of interests in the ultimate parent company of the Owner Participant entity shall be deemed not to be a transfer of OP Interests), except as and to the extent permitted by, and in accordance with the terms and conditions of, this Article XII. Section 12.01 and Section 12.02 shall not apply to any Transfer to Lessee or otherwise required by the Operative Documents or XM Agreements or in connection with any exercise of remedies under the Effective Equity Wrap.

This Article XII and related definitions hereto with respect to the process of transfers and approval of transferees only are included solely for the benefit of Lessee and Owner Participant and may be amended by them (in a writing signed by them) without approval of Indenture Trustee, the Note Purchasers or any other parties hereto, provided that, for the avoidance of doubt, no such amendment shall in any way limit or reduce the consent or approval rights of Indenture Trustee or the Noteholders under this Article XII or otherwise adversely affect, in any respect, the interests of Indenture Trustee or the Noteholders.

SECTION 12.02. Transfers After the Closing Date. Commencing eighteen (18) months after the Closing Date (or such earlier date on which Owner Participant becomes subject to a Regulatory Event or an Event of Default occurs and is continuing), Owner Participant may transfer all or any portion of its Beneficial Interest (whether or not the same shall then have been pledged or mortgaged under the Indenture, but subject to the Lien of the Indenture if then in effect) to any Person, and Owner Participant may permit (and shall not be in breach of this Participation Agreement if there occurs) a transfer of all or any portion of the OP Interests to any Person (such transferee, with respect to either a transfer of the Beneficial Interest or a transfer of the OP Interests, a “Transferee”), in each case only in compliance with and upon satisfaction of the following conditions:

(a) Except during any period in which an Event of Default has occurred and is continuing, Owner Participant shall provide Lessee and, while the Lien of the Indenture is in effect, Indenture Trustee written notice of any intention to transfer the Beneficial Interest or OP Interests, setting forth the Beneficial Interest or OP Interests to be transferred. Along with or subsequent to delivery of such notice, Owner Participant shall provide Lessee a list of not less than ten (10) potential Transferees. Within ten (10) Business Days of Lessee’s receipt of such list, Lessee shall notify Owner Participant as to which of such potential Transferees are acceptable in Lessee’s reasonable business judgment, taking into account such matters as Lessee reasonably determines to be relevant, and if there are fewer than ten (10) acceptable potential Transferees, Lessee shall add additional potential Transferees to such list so that it has at least ten (10) (such acceptable potential Transferees being referred to as “Permitted Transferees”). Owner Participant or the OP Interest holder (as the case may be) may, but is not required to, enter into a binding contract for the proposed transfer of the Beneficial Interest or OP Interests during the three (3) months commencing upon receipt of Lessee’s response to such list. During such period, Lessee shall, to the extent reasonably so requested by Owner Participant and at the expense of Owner Participant, use all reasonable efforts to assist Owner Participant in completing the proposed transfer; provided, however, that Lessee shall not be obligated to amend, waive, or modify any provision of any Operative Document or XM Agreement. If (i) Owner Participant has used reasonable efforts to enter into a binding contract for the proposed transfer of the Beneficial Interest or OP Interests to a Permitted Transferee during such period and (ii) has not received one or more cash offers not subject to due diligence or financing

contingencies, unless such contingencies are satisfied within such period (or such longer period as is acceptable to Owner Participant in its sole discretion) during such period from Permitted Transferees equal to or greater than the sum of (A) the excess of Stipulated Loss Value over the unpaid principal amount of the Notes then outstanding and (B) the equity portion of any accrued but unpaid Rents (or if the proposed transfer is for less than all of the Beneficial Interest or OP Interests, a pro rata portion thereof), Owner Participant may provide Lessee written notice that it wishes to seek a purchaser of the Beneficial Interest or OP Interests outside the group of Permitted Transferees (an “Outside Transfer Notice”). If Lessee does not purchase the Beneficial Interest under Section 10.01(d) within sixty (60) days after receiving the Outside Transfer Notice or waives the right under such section with respect to the proposed transfer, Owner Participant may, during the three (3) months commencing upon expiration of such sixty (60) day period, enter into a binding contract for the proposed transfer of the Beneficial Interest or OP Interests to any Person so long as the Transferee is not a Competitor or Competitor Related Party and the transfer meets the other requirements of this Section 12.02. If Owner Participant fails to enter into a binding contract for the proposed transfer within such three (3) month period, or transfers less than all of its Beneficial Interest or OP Interests, the provisions of this Section 12.02(a) shall again apply to any subsequent transfer and must be complied with by Owner Participant to transfer its Beneficial Interest or OP Interests. The provisions of this Section 12.02(a) shall not apply in the event Lessee does not timely deliver the Final Notice contemplated by Section 18(a) of the Lease (either with respect to the Basic Term or the Renewal Term), or if a Bankruptcy Default or an Event of Default is continuing;

(b) the Transferee shall not be a Competitor or a Competitor Related Party;

(c) in the case of a transfer of the Beneficial Interest to any Person other than Lessee or an Affiliate thereof, the Transferee or an Affiliate thereof guarantying the obligations of the Transferee pursuant to a guaranty agreement substantially identical to the form of Owner Participant Guarantee set forth as Exhibit L (or otherwise reasonably satisfactory to Lessee, Trust Company and, if the Lien of the Indenture shall then be in effect, Indenture Trustee) shall be (i) a financial institution, corporation, leasing company or other institutional investor whose net worth at the time is at least $75,000,000 (a “Permitted Institution”), (ii) a financial institution, corporation, leasing company or other institutional investor the obligations of which, as Owner Participant under the Operative Documents, are guarantied or supported by a letter of credit or similar instrument issued by a Permitted Institution, pursuant to a guaranty agreement substantially identical to the form of Owner Participant Guarantee Agreement set forth as Exhibit L (or in the case of a letter of credit, other instrument or different form of guarantee, otherwise reasonably satisfactory to Lessee, Trust Company and, if the Lien of the Indenture shall then be in effect, Indenture Trustee) or (iii) an Affiliate of Owner Participant; provided that if such Affiliate is not a Permitted Institution, Owner Participant shall guaranty the obligations of such Affiliate as Owner Participant under the Operative Documents (or shall procure that Owner Participant Guarantor provides such a guaranty) pursuant to a guaranty agreement substantially identical to the form of Owner Participant Guarantee Agreement set forth as Exhibit L (or otherwise reasonably satisfactory to Lessee, Trust Company and, if the Lien of the Indenture shall then be in effect, Indenture Trustee);

(d) assuming the accuracy of the representations made by Lessee in Sections 4.01(j) and (k) and by the Transferee set forth in Section 12.02(f) below, and assuming compliance by all Noteholders with the representation contained in Section 4.08(b), no such

transfer shall violate any provision of, or create a relationship which would be in violation of, any Applicable Laws, including, without limitation, applicable securities laws, any agreement to which Owner Participant or the Transferee is a party or by which it or any of its property is bound and such transfer to or ownership by such Transferee will not result in a “prohibited transaction” as defined in Section 406 of ERISA or Section 4975 of the Code, which “prohibited transaction” is not subject to a complete exemption pursuant to ERISA or the rules, regulations, releases or bulletins adopted thereunder;

(e) in the event of any Transfer of a Beneficial Interest other than to Lessee or an Affiliate of Lessee, the Transferee shall enter into an Owner Participant Substitution Agreement, substantially in the form of Exhibit M (or otherwise reasonably satisfactory to Lessee, Trust Company and, if the Lien of the Indenture shall then be in effect, Indenture Trustee), whereby the Transferee shall confirm that it is a domestic corporation or limited liability company (which, if a limited liability company, (x) is organized under the law of a state of the United States, (y) has not more than two beneficial owners, and (z) each beneficial owner of which is a domestic corporation within the meaning of Section 7701(a) of the Code), and that such Transferee has the requisite power and authority to enter into and to carry out the transactions contemplated hereby and in each Operative Document and XM Agreement to which Owner Participant is or will be a party, and that it shall be deemed a party to each of such Operative Documents and XM Agreements and shall agree to be bound by all the terms of, and to undertake all the obligations of the transferor to be performed on or after the date of such transfer contained in, each of such Operative Documents and XM Agreements, and whereby such Transferee shall make representations and warranties reasonably requested by Lessee, Trust Company and (if the Lien of the Indenture shall then be in effect) Indenture Trustee similar in scope to the representations and warranties contained in Section 4.03, (if the Transferee is Lessee or an Affiliate of Lessee, the transferee shall enter into an Owner Participant Substitution Agreement containing such representations other than as set forth in clause (x), (y) and (z) above); provided that such Transferee delivers to Lessee, Trust Company and Indenture Trustee a written representation and warranty (or an opinion of counsel reasonably satisfactory to Lessee, Trust Company and Indenture Trustee) that (i) it is not acquiring the interest being conveyed with assets subject to Title I of ERISA or Section 4975 of the Code or (ii) such transfer to or ownership by such Transferee will not result in a “prohibited transaction” as defined in Section 406 of ERISA or Section 4975 of the Code, which “prohibited transaction” is not subject to a complete exemption pursuant to ERISA or the rules, regulations, releases or bulletins adopted thereunder;

(f) the transferring Owner Participant shall have provided twenty (20) days (or seven (7) days with respect to a transfer to an Affiliate as contemplated by Section 12.02(b)(iii)) prior written notice of such transfer to Indenture Trustee, Trust Company and Lessee, which notice shall specify (i) such information and be accompanied by evidence as shall be reasonably necessary to establish compliance with this Article XII and (ii) the name and address (for the purpose of giving notice as contemplated by the Operative Documents) of the Transferee;

(g) whether or not the Transfer actually occurs, the transferring Owner Participant shall pay or cause to be paid on an After-Tax Basis all reasonable fees, expenses, disbursements and costs (including, without limitation, legal and other professional fees and expenses) incurred by Owner Trustee, Indenture Trustee or Lessee, in connection with any transfer pursuant to this Article XII; and

- 69 -

(h) in the case of a Transfer of a Beneficial Interest, the transferring Owner Participant or the Transferee shall have delivered to Lessee, Trust Company and, if the Lien of the Indenture shall then be in effect, Indenture Trustee, an opinion of counsel in form and substance reasonably satisfactory to each of them, as to the due authorization, execution, delivery and enforceability of the agreement or agreements referred to in clause (c) or (e) of this Section 12.02, and as to the matters referred to in clause (d) of this Section 12.02;

(i) the Lessee shall not be obligated to pay any greater amount or incur any greater obligation than that which it would have been obliged to pay or incur under the Lease or other XM Agreements if no transfer or assignment had taken place, and the terms and conditions of the Lease and the other XM Agreements insofar as they relate to the rights and obligations of Lessee shall not be altered;

(j) unless otherwise agreed by Holdings or Lessee in writing, the total number of Owner Participants shall not exceed four (4), after giving effect to the consummation of the proposed transfer (where Owner Participants that are Affiliates shall constitute a single Owner Participant for purposes of such limit), and upon the consummation of a transfer one Owner Participant (together with its Affiliates) shall retain a Beneficial Interest equal to or greater than 60% and shall retain all rights and powers necessary to make all substantive decisions (subject to any requirement to obtain approval of other Owner Participants, in the case of Fundamental Decisions) to be made by Owner Participant under any Operative Document or XM Agreement;

(k) unless otherwise agreed by Holdings or Lessee in writing, if the transferring Owner Participant is the Owner Participant on the Closing Date, such Owner Participant (together with its Affiliates) shall, upon the consummation of the proposed transfer, either (i) retain a Beneficial Interest equal to or greater than 60% of Lessor’s Estate and retain all rights and powers necessary to make all substantive decisions (subject to any requirement to obtain approval of other Owner Participants, in the case of Fundamental Decisions) required to be made by Owner Participant under any Operative Document or XM Agreement or (ii) shall retain no Beneficial Interest in its capacity as Owner Participant; and

(l) if an Effective Equity Wrap is in place and is addressed to, held by or enforceable by the transferring Owner Participant, Owner Participant (and not Lessee) shall be responsible for any modifications to the Effective Equity Wrap necessary or appropriate to have it addressed to, held by or enforceable by (in whole or in part) the Transferee, and any such modifications or failure to so modify shall not result in a Default or Event of Default under any Operative Document; provided, however, that Lessee shall, at Owner Participant’s request, cooperate in all reasonable respects with Owner Participant’s efforts to make such modifications, and Owner Participant shall reimburse Lessee for all reasonable out-of-pocket expenses incurred in connection with such cooperation.

If a Bankruptcy Default or Event of Default shall have occurred and be continuing, any matter under this Section 12.02 that would otherwise need to be reasonably satisfactory to Lessee (or to meet another reasonableness requirement where Lessee is making the reasonableness determination) shall be deemed to be reasonable without any determination of reasonableness or satisfaction being made by Lessee.

SECTION 12.03. Effect of Transfer. Upon any transfer by Owner Participant in accordance with Section 10.01, Section 11.07 or this Article XII, the Transferee, the transferring Owner Participant (if it then retains any Beneficial Interest) and each other Transferee which then holds any Beneficial Interest collectively shall be deemed “Owner Participant” for all purposes of the Operative Documents and each reference herein to Owner Participant making such transfer shall thereafter be deemed a reference to such Persons for all purposes, except as provided in the succeeding sentence. In the event of a transfer of the entire Beneficial Interest effected in accordance with Section 10.01, Section 11.07 or this Article XII, the Person making such transfer (and any Person guarantying the obligations of such transferor) shall be released, to the extent of the obligations assumed by the Transferee (and, if required hereunder, guarantied by an Affiliate of such Transferee), from their respective liabilities hereunder and under the other Operative Documents to which either of them is a party in respect of obligations to be performed on or after the date of such transfer. Unless otherwise agreed in writing between the transferring Owner Participant and the Transferee, where copies of any such agreement are provided to Lessor, Indenture Trustee and Lessee, all payments made to “Owner Participant” on the applicable transfer date shall be made to the transferring Owner Participant.

SECTION 12.04. Cooperation. Lessee agrees that it shall, to the extent reasonably so requested by Owner Participant and at the expense of Owner Participant (except to the extent Lessee is obligated to pay such expenses under other provisions of the Operative Documents, subject to the provisions of Section 6.02(d) and Section 12.02(a), which shall prevail), use reasonable efforts to assist Owner Participant in effecting any transfer of Beneficial Interest pursuant to this Article XII.

SECTION 12.05. Proceeds of Effective Equity Wrap. (a) If Owner Participant receives payment in full of the equity component of Stipulated Loss Value and all other accrued and unpaid obligations secured by Effective Equity Wraps (other than an Effective Equity Wrap contemplated by Alternative 3 to Schedule V hereto), Owner Participant shall Transfer the Beneficial Interest, as is and where is, to Lessee (or the Person making such payment, as Lessee may direct in writing), free and clear of Lessor Liens (provided that only Lessor, and not Owner Participant, shall be responsible for removal of Lessor Liens and the existence of any Lessor Liens shall not impair or delay Owner Participant’s rights, including its right to receive payment under any Effective Equity Wrap) and Owner Participant Liens, but otherwise without warranty, and Lessee shall or shall cause such Person to assume all obligations related to such Beneficial Interest pursuant to an Owner Participant Substitution Agreement, substantially in the form of Exhibit M, or as provided in Section 12.02(e) if the Transferee is Lessee or an Affiliate of Lessee (or otherwise reasonably satisfactory to the transferring Owner Participant, Lessee, Trust Company and, if the Lien of the Indenture shall then be in effect, Indenture Trustee). If Owner Participant receives payment in full of the equity component of Stipulated Loss Value and all other accrued and unpaid obligations secured by Effective Equity Wraps contemplated by Alternative 3 to Schedule V hereto, Owner Participant shall Transfer the Beneficial Interest, as is and where is, to the Person making such payment, free and clear of Lessor Liens (provided that only Lessor, and not Owner Participant, shall be responsible for removal of Lessor Liens and the existence of any Lessor Liens shall not impair or delay Owner Participant’s rights, including its right to receive payment under any Effective Equity Wrap) and Owner Participant Liens, but otherwise without warranty, and Lessee shall cause such Person to assume all obligations related to such

Beneficial Interest pursuant to an Owner Participant Substitution Agreement, substantially in the form of Exhibit M, or as provided in Section 12.02(e) if the Transferee is Lessee or an Affiliate of Lessee (or otherwise reasonably satisfactory to the transferring Owner Participant, Lessee, Trust Company and, if the Lien of the Indenture shall then be in effect, Indenture Trustee).

(b) So long as the Lien of the Indenture is in effect, without the consent of Indenture Trustee acting at the direction of the Majority Interest of Noteholders, Lessee shall ensure that (i) any Effective Equity Wrap contemplated by Alternative 1 or Alternative 2 to Schedule V hereto entered into after the Closing Date (and the Equity Wrap Documents relating thereto) shall contain terms and conditions no less favorable to Indenture Trustee and Noteholders than those set forth in the Effective Equity Wrap (and the Equity Wrap Documents relating thereto) in effect on the Closing Date, or (ii) the Effective Equity Wrap (and the Equity Wrap Documents relating thereto) in effect on the Closing Date shall not be amended in any manner that would materially adversely affect the interests of the Indenture Trustee or the Noteholders.

SECTION 12.06. No Effect on Lease or Lease Payments. For the avoidance of doubt, no payment made pursuant to an Effective Equity Wrap or Transfer of the Beneficial Interest as contemplated by Section 12.05 nor any other Transfer of the Beneficial Interest that results in Lessee or an Affiliate of Lessee owning the Beneficial Interest shall reduce or modify Lessee’s obligations to pay Rent or other amounts (including Stipulated Loss Value and the EBO Amount) under the Lease or result in an adjustment of the Factors under Section 11.05 and the Lease shall continue in full force and effect after giving effect to any such payment or Transfer.

If Recipient is required to disclose Proprietary Information pursuant to clause (F) of this paragraph, Recipient shall (to the extent permitted by law) promptly notify Lessee of such disclosure requirement and upon the request of Holdings or Lessee, as applicable, shall to the extent practicable, at Holdings’ or Lessee’s sole cost and expense and with counsel reasonably satisfactory to Recipient, cooperate with reasonable requests of Holdings or Lessee, as applicable, in contesting such disclosure. If after such contest disclosure is still required, then Recipient shall seek, if practicable, confidential treatment of such information from the applicable party. Notwithstanding any provision of this Article XIII to the contrary, the Owner Participant may, at any time after the date that is eighteen (18) months after the Closing Date, disclose Proprietary Information or information regarding the contents of the Operative Documents and the XM Agreements and the identity of the parties thereto to any prospective or actual Transferee in connection with a transfer, or discussions of a transfer permitted by Section 12.01 or 12.02 or as contemplated by the last sentence of Section 12.01 or a transfer of title to Buyer’s Transponders after the Lease Term, subject to the agreement in writing of such prospective or actual transferee to confidential treatment of such information (and to compliance with all side letters relating to competitive or confidential information or separate nondisclosure agreements).

(b) “Proprietary Information” shall be defined as proprietary information of Lessee in any form, including without limitation, all writings, memoranda, copies, reports, financial statements, papers, surveys, analyses, drawings, letters, computer printouts, software, specifications, data, graphs, charts, sound recordings and/or pictorial reproductions which have been reduced to written form. Proprietary Information shall be marked as proprietary by Lessee with an appropriate legend, marking, stamp or other obvious written identification prior to disclosure (or if such disclosure occurred prior to the date hereof, within thirty (30) days of the date hereof). In the event that Lessee discloses its Proprietary Information to Recipient other than in the manner provided for in this paragraph (b), then Holdings or Lessee, as applicable, shall promptly inform Recipient that such information is deemed proprietary and shall provide Recipient with a brief written description of such information within thirty (30) days of such disclosure, identifying therein the manner, place, and date of such disclosure and the names of Recipient’s representatives to whom such disclosure was made whereupon the provisions of this agreement shall become applicable to such Proprietary Information.

In the event of such requested destruction, Recipient shall provide to Holdings or Lessee, as applicable, written certification of compliance therewith within thirty (30) days of such written request. The disclosure of Proprietary Information under this Section 13.01 shall not be construed as granting either a license under any patent, patent application, or copyright, or any right of ownership in said Proprietary Information, nor shall such disclosure constitute any representation, warranty, assurance, guaranty, or inducement by Lessee with respect to infringement of patents or other rights of others.

(e) This Section 13.01 contains the entire understanding between the parties with respect to the safeguarding of Proprietary Information, supersedes all prior communications and understandings with respect thereto, shall inure to the benefit of each of Holdings and Lessee, its Affiliates and its successors and assigns, and shall be binding upon all parent, subsidiary, and successor organizations of Recipient. Recipient shall be responsible for any breach of this Section 13.01 by such Recipient (or its parent, subsidiary and successor organization), by its special counsel listed in Item 5 to Schedule II hereto, its auditors and financial advisors (not including the Independent Appraiser) unless it shall obtain a written agreement from such Person to be bound by the terms of this Section 13.01, in which case Recipient shall not be liable for any breach by such Person of the terms thereof. By way of illustration only and not by way of limitation, the provisions of this Section 13.01 shall inure to the benefit of XM and Holdings.

If any Person is required to disclose information pursuant to clause (F) of this paragraph, other than reports or other disclosures required to be made to the FCC, such Person shall (to the extent permitted by law) promptly notify the other parties hereto of such disclosure requirement. This Section 13.02(b) shall inure to the benefit of and be binding upon the parties hereto, their respective successors and assigns. Each party shall be responsible for any breach of this Section 13.02(b) by its Affiliates, officers, directors, employees, agents, counsel, accountants and other representatives to whom it provided such information; provided that if such Person obtains a written confidentiality agreement substantially to the effect of this Section 13.02(b) such Person shall not be liable for any such breach. A breach of this provision shall not constitute a Default, Lease Default or Lease Event of Default or Indenture Default or Indenture Event of Default; Lessee, Owner Trustee, Indenture Trustee, Note Purchasers and Owner Participant, as the case may be, shall be responsible only for liquidated damages of One Thousand Dollars ($1,000) as a result of a breach of this Section 13.02(b) and shall not be responsible for any consequential or incidental or other damages or attorneys’ fees incurred in connection with a suit or breach or enforcement of this Section 13.02(b).

Lessor, Indenture Trustee and Owner Participant hereby acknowledge that providing information to certain insurers in connection with obtaining Additional Insurance may require compliance with Export Control Laws, including ITAR.

SECTION 13.16. Other Cooperation.
