- 10 -



---

| | assuming only two (2) mobile aftermarket SDARS providers and less than thirty-three percent (33%) assuming that there are three (3) mobile
aftermarket SDARS providers. XMs share of mobile aftermarket SDARS subscribers shall be based on a mutually agreed upon source, such as the 10-Q and 10-K filings of XM and Sirius, and shall be based on the most recent figures available at the

| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Installation-Triggered Renegotiation. XM may initially trigger a renegotiation of this Agreement four (4) years following the Trigger Date if the number of Enabled GM Vehicles
by that time is less than 1.24 million units and every two (2) years during the Term thereafter, if the number of Enabled GM Vehicles during the prior two (2) years is inconsistent with the OEM market demand for SDARS radios. Evidence

|XM Share of Mobile SDARS aftermarket |  | Multiplier (times install target % of new GM Vehicles across the

|[***]                                |  | [***]                                                                               
|[***]                                |  | [***]                                                                               
|[***]                                |  | [***]                                                                               
|[***]                                |  | [***]                                                                               



| | (iii) | For example, if [***] percent ([***]%) of non-GM OEM vehicles were installed with satellite capable radios in a given Model Year and XMs share of the mobile SDARS aftermarket
were [***] percent ([***]%), then Distributor, for purposes of determining consistency with OEM market demand, would need to install ([***]%), or [***] percent ([***]%), of GM Vehicles with XM Receivers. For purposes of this clause (iii),
Distributors new GM Vehicle install requirement shall be deemed to be satisfied if Distributor installs the lesser of (A) the number of Enabled GM Vehicles required by this clause (iii), or (B) 600,000 XM Receivers per year for each
of the two (2) years in the measurement period.

the thirty (30)-day period following the notice described in this Section 3(c).

(d) If the FCC revokes XMs SDARS license as a
result of the action(s) or inaction(s) of XM, then Distributor, at its option, shall have the right to declare XM in material breach of this Agreement, and such revocation shall not constitute a force majeure event under Section 10.

4. PAYMENTS TO DISTRIBUTOR:

|                |  |                               |        
|--------------- |  | ----------------------------- | -------

|* | If Distributor is unable (for reasons not attributable to XMs delay in launching services) to install XM Receivers beginning with Model Year 2002, then the payments set forth
in the table above shall be delayed and shall commence in the calendar quarter immediately following the calendar quarter in which Distributor first installs reasonable quantities of XM Receivers in GM Vehicles.
|- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In the event that this Agreement is terminated other than on the last day of a calendar year, then the payment set forth in the table above for such calendar year shall
be prorated to reflect the number of days during such calendar year that this Agreement was in effect. The payments set forth in the table above with respect to 2001 and 2002 shall be due and payable in two equal installments during the 2002
calendar year on or before September 30 and December 31, 2002. Subsequent calendar year payments, shall be due and payable in four equal installments on or before March 31, June 30, September 30 and
December 31 of the pertinent calendar year.

In lieu of making the guaranteed payments for each of the 2003, 2004, 2005 and 2006 calendar years, XM
entered into the Note Purchase Agreement, and issued to GM a senior secured convertible note in the amount of $89,042,387 (the Note), which has been paid in full. In May 2006, XM satisfied in full the guaranteed payments it owes to
Distributor for each of the 2007, 2008 and 2009 calendar years by paying to GM $237,000,000, which amount represented the present value of such guaranteed payments, as agreed by XM and Distributor. Accordingly, all amounts payable by XM to
Distributor under Section 4(a) hereof have been paid in full. The Parties also acknowledge and agree that the payment of $237,000,000 referenced above shall not be subject to retroactive adjustment by the Parties based on the level of
performance of Distributor. The Distributor remains subject to the requirements of the first paragraph of Section 4(a). The Parties agree that if either Party initiates a renegotiation of the Agreement pursuant to the terms of
Section 3(b), any adjustment that would have applied to the $237,000,000 referenced above shall instead be applicable to other payments that would be payable to GM hereunder.

(b) Installation Commission. During the Term, XM agrees to pay Distributor an Installation commission as set forth below (the Installation
Commission). Distributor shall invoice XM (on a mutually agreed upon form) at the end of each calendar month for Installation Commissions earned during such month



| | (i) | New Enabled GM Vehicle, XM agrees to pay Distributor a commission of [***] for each New Enabled GM Vehicle. Each invoice shall include the Vehicle Identification Number
(VIN) of each GM Vehicle for which an Installation Commission is payable, the XM Receiver identification number for each such GM Vehicle and any other information reasonably necessary to compute the Installation Commission.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | The invoice shall be due and payable within thirty (30) days following receipt by XM. Distributor shall not invoice XM for an Installation Commission covered in section
(i) before the Vehicle Ship Date.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(c) Subscriber Incentive. In addition to the Installation Commission and subject to
the following sentence, XM agrees, during the Term, to pay Distributor a [***] commission (the Subscriber Incentive) for each GM/XM Subscriber (excluding subscriptions to the XM Services in GM Affiliate Vehicles) who Purchases a
New Enabled GM Vehicle. The subscriber must



- 13 -



---

subscribe to the XM Service within twelve (12) months of the initial Purchase (consumer delivery date) of such an Enabled GM Vehicle (a Qualifying
GM/XM Subscriber). If a Qualifying GM/XM Subscriber for whom a Subscriber Incentive is payable fails to pay XM at least [***] for receipt of the Base Subscription Service, then XM shall have the right to credit the difference between the
Subscriber Incentive paid and the amount actually received by XM on account of such GM/XM Subscriber to future Subscriber Incentive payments. The Subscriber Incentive shall be paid in two (2) equal installments (Activation and Loyalty), the
first (Activation) of which shall be due and payable no later than thirty (30) days following the end of the calendar month during which a Qualifying GM/XM Subscriber initially subscribes to the XM Service. The second (Loyalty) of which shall
be due and payable no later than thirty (30) days following the end of the calendar month during which such Qualifying GM/XM Subscriber makes his initial three (3)-month subscriber payment for receipt of the XM Service. In no event shall the
Subscriber Incentive be payable more than one time with respect to any one XM Receiver.

(d) Revenue Share. During the Term, Distributor
shall receive a percentage of the revenue received by XM from GM/XM Subscribers (excluding subscriptions to the XM Services in GM Affiliate Vehicles) for the Base Subscription Service (the Revenue Share). The percentage shall depend on
the number of Enabled GM Vehicles (including GM Affiliate Vehicles) at the time such revenue is received as follows:



|                                     |  |                                           
|------------------------------------ |  | ------------------------------------------
|If Number of Enabled GM Vehicles is: |  | Then Distributors Revenue Share shall be:
|[***]                                |  | [***]                                     
|[***]                                |  | [***]                                     
|[***]                                |  | [***]                                     
|[***]                                |  | [***]                                     
|in excess of [***]                   |  | [***]                                     

The Revenue Share percentages set forth in the table above shall apply to a Base Subscription
Service price between [***] and $9.99 per month. If, in response to competitive pressures, the Base Subscription Service price falls below [***] per month, then the Parties shall negotiate in good faith to modify the Revenue Share in an equitable
manner to reflect the realities of the market. If XM fundamentally changes its business model (e.g., employs a more aggressive advertising model), and, as a result of such change, the Base Subscription Service price falls below [***] per month, then
the Revenue Share payable to Distributor shall be determined as if the Base Subscription Service price were $9.99 per month. Likewise, if the Base Subscription Service price is more than $9.99 per month, then the Revenue Share shall be determined as
if the Base Subscription Service price were $9.99 per month.

The Revenue Share shall be due and payable no later than thirty
(30) days after the end of each calendar month during the Term based upon subscriber revenues collected during such month. In the event that the applicable Revenue Share percentage changes in the middle of a calendar month, XM shall make
payments to GM using the Revenue Share percentage previously in effect, and, promptly after making such payment, XM and GM shall cooperatively analyze the applicable data and, as appropriate, XM shall make a follow-up adjusting payment to GM
reflecting the Revenue Share percentage then in effect in accordance with this Section 4(d).

(e) Revenue Share (or other Compensation) for GM Affiliate Vehicles. Revenue share, if any, (or other
compensation, if any) payable with respect to subscribers to the XM Service in GM Affiliate Vehicles that are enabled to receive the XM Service shall be as may be agreed from time to time by XM and the applicable GM Affiliate.

(f) Late Payment Interest. In the event XM shall fail to make any payment due to Distributor pursuant to this Section 4, XM shall pay interest on
such unpaid amount, payable from time to time on demand, from the date such amount shall have become due to the date of payment thereof (after as well as before judgment), accruing on a daily basis, at a per annum rate equal to the sum of the
Interest Rate in effect at such time plus one percent (1.0%). The existence of late payment interest shall not imply any right by XM to make any payments due hereunder late and shall not be deemed to be a waiver of Distributors right to demand
payment of amounts payable hereunder when due.

5. ADVERTISING AND PROMOTIONAL COMPONENTS:

(a) Advertising Availability. During each of the calendar years set forth in the table below that this Agreement is in effect, XM agrees to make available
to Distributor a number of advertising spots (the "Spots") on XM channels comprising the XM Service representing the following dollar amounts (expressed in thousands):

Spot dollars are to be re-distributed between calendar years in the event both parties, XM and the Distributor, mutually agree on the revised allocation. In the event that spot dollars are re-distributed, formal
documentation of the mutual decision is required including, but not limited to, the dollar value re-distributed.



|              |  |       |  |       |  |       |  |       |  |       |  |       |  |       |  |       |  |

|Dollar Value: |  |       |  |       |  |       |  |       |  |       |  |       |  | [***] |  | [***] |  | [***]

(b) The Spots shall only be used by Distributor to advertise and promote GM products and services.
Except as set forth above, if Distributor does not use all of the Spots made available to Distributor during any calendar year, Distributor may not carry such unused Spots forward into any subsequent calendar year during the Term. Distributor, at
its expense, shall create, produce and deliver the Spots to the location(s) specified by XM. The Spots shall not be adverse to, or competitive with, XMs business(es) or require XM to make any payments to a third party or obtain any consents to
insert the Spots on the XM Service. Distributor will indemnify the XM Indemnitees as provided herein in connection with Distributors use of the Spots (including, without limitation, the content thereof), and the Spots cannot be resold by
Distributor to a third party. The dollar value of the Spots will be priced based on the then-current CPM rate sheets. Placement of the Spots shall be mutually agreed upon by the Parties.

(c) Market Support Funds. XM agrees that for each calendar year during the period commencing
January 1, 2001, and ending December 31, 2009, XM shall allocate [***] per year, and during the period commencing January 1, 2010 and ending December 31, 2012, XM shall allocate [***] per year, of its annual advertising budget to
Distributor to be placed through a mutually agreed agency, provided that such support funds pertain to the XM Service and are consistent with XMs positioning and branding of the XM Service. The annual budget will be utilized for, but is not
limited to, mutually agreed upon advertising opportunities, dealer promotions, on-site activities, training, and vehicle literature. Before initiating agency work, both parties will mutually agree to the initiative(s) and term(s).

(i) Market Support dollars are to be re-distributed between calendar years in the event both parties, XM and the Distributor, mutually agree on the
revised allocation. In the event that Market Support funds are re-distributed, formal documentation of the mutual decision is required including, but not limited to, the dollar value re-distributed.

(ii) Distributor agrees to monthly reporting of the XM value realized through GM brand and field activities. XM agrees to monthly reporting of GM Market
Support fund activities, monies spent, committed and forecast.

(d) Initial Free Service. Distributor shall use reasonable efforts to have
all GM Vehicle Purchasers of Enabled GM Vehicles subscribe to the XM Service. As an incentive to increase subscriptions to the XM Service by Purchasers of new Enabled GM Vehicles, Distributor is authorized to offer Purchasers of new Enabled GM
Vehicles (excluding GM Affiliate Vehicles) up to [***] months of free trial service to the Base Subscription Service. If Distributor elects to offer a free trial service to Purchasers of new GM Vehicles, then, within a reasonable period of time
following receipt of the report described in Section 7(a), XM will activate the XM Receiver in the new GM Vehicles identified in such report.

(e) XM and Distributor shall mutually agree on the implementation of a marketing plan to attract additional subscribers to the XM Service by targeting Purchasers of Enabled GM Vehicles (excluding GM Affiliate Vehicles) who have not
subscribed to the XM Service beyond the initial trial service period. Such marketing plan shall include steps which shall be agreed to by the Parties to advise the Purchasers that their Enabled GM Vehicles include an XM Receiver. XM agrees to pay
Distributor a Revenue Share for subscribers who initially subscribe on a self-paid basis to the XM Service after twelve (12) months from the initial Purchase of an Enabled GM Vehicle; in consideration therefor, Distributor agrees to pay a
portion of the marketing costs associated with targeting such subscribers, with such portion to be equal to the then-applicable Revenue Share percentage.

6. BANDWIDTH USAGE; STUDIO ACCESS; AUDIO CONTENT:

(a) During the Term and for each Bandwidth Extension Year, XM agrees to allocate
for use by Distributor [***] of the bandwidth on the XM System for audio and/or data transmissions by Distributor to GM/XM Subscribers. Use of such bandwidth shall be subject to compliance with applicable law, including without limitation, rules and
regulations of the FCC (FCC Rules). If requested by Distributor and permitted under applicable law, including, without limitation, FCC Rules, XM will make this bandwidth

shall provide XM with all information reasonably necessary to activate and/or to deactivate the XM Receivers by Distributors customers that are not GM/XM Subscribers.

(b) Distributor agrees to give XM at least ninety (90) days prior notice of its intent to utilize the bandwidth allocated to Distributor

(c) To the extent Distributor elects to utilize any or all of the bandwidth allocated to it hereunder, Distributor, at its expense, shall
deliver to a location in the Territory designated by XM a complete audio signal and/or data transmission, as the case may be, by transmitting such signal and/or data via a mutually acceptable means and in a form that will not require XM to modify
the signal and/or data in order to receive or to transmit such signal and/or data over the XM System. XM, at its expense, shall furnish all other facilities necessary for the receipt of Distributors transmission and for the retransmission of
such signals and/or data to subscribers authorized to receive such signals and/or data.

(d) Distributor agrees that the technical quality
of each audio signal and/or data transmission transmitted by Distributor to XM shall be at least equal to the technical quality of the audio signals and/or data transmissions delivered to XM by any third party distributor of audio services and/or
data transmissions, respectively.

(e) Distributor shall not use the bandwidth allocated to it hereunder to create or transmit music or
entertainment radio services that compete with, or otherwise use such bandwidth in a manner that could reasonably be expected to adversely interfere with, the XM business(es). XM shall not use the remainder of the bandwidth to create a service
targeting new GM Vehicle Purchasers that packages together the essential features of the current OnStar features as described in Attachment 2 attached hereto.

(f) Without limiting the provisions of Section 9(b), Distributor shall indemnify and hold harmless the XM Indemnitees from and against any and all Costs arising out of Distributors use of such bandwidth,

(g) During the Term, XM shall provide to Distributor reasonable access to and exclusive use of a radio programming studio (the actual studio used may
vary) in XMs radio programming studio facilities for up to 100 hours during any calendar month, and up to an aggregate of 500 hours during any calendar year, at no cost to Distributor. Distributor shall make any request for access at least 30
days prior to the date it wishes to have access to and use of a radio programming studio in XMs radio programming studio facilities; provided that such notice has been given, XM shall not unreasonably deny timely access. XM shall not be
responsible for providing staffing or production support to Distributor in connection with Distributor's use of any XM radio programming studio.

(h) During the Term, XM will make available to Distributor, for prepackaging and distribution on Distributor's Virtual Advisor, at no cost to Distributor (except as provided in the last sentence of this paragraph), XM audio

competitor of Distributor. The repackaged programming shall not exceed 5 minutes per day in any one category of content. It shall be branded on-air as XM content and include promotions of the XM Service and referrals to the XM Service for similar
content. Distributor shall promote availability of XM Service programming in marketing communications associated with any distribution of such audio content. XM and Distributor shall work cooperatively to identify information or content that each

twelve (12) months, (ii) the makes and models in which Distributor is installing or proposing to install XM Receivers, and (iii) the types of packages in which the XM Service may be included. XM acknowledges that nothing contained in
this Agreement shall be construed as obligating Distributor to fulfill any of the projections or plans discussed with XM at such meetings, provided that the provisions of Section 3(b)(ii) shall continue to apply. In addition, from June 1,
1999 through May 30, 2000, XM will provide Distributor monthly reports and hold quarterly meetings to inform Distributor fully about XMs progress toward the Commencement Date. From June 1, 2000 through June 30, 2001, XM and

(b) Distributor and XM shall meet on a quarterly basis to review the installation rates of XM Receivers in GM Vehicles, the manner in which XM Receivers
are packaged with various GM vehicles and the percentage of purchasers of such Enabled GM Vehicles who become GM/XM Subscribers. In the event that fewer than 70% of the purchasers of Enabled GM Vehicles over any six-month period become GM/XM
Subscribers in connection with the purchase of such Enabled GM Vehicles, then (i) Distributor may, in its sole discretion, redirect the moneys payable by XM to Distributor hereunder to advertising and/or marketing efforts intended to increase
the percentage of such purchasers of Enabled GM Vehicles who become GM/XM Subscribers, and (ii) XM and Distributor shall meet to review installation forecasts and marketing plans relating to XM Receivers and the XM System, with the purpose of
making adjustments intended to increase the percentage of such purchasers of Enabled GM Vehicles who become GM/XM Subscribers.

(c)
Distributor shall purchase XM Receivers for installation only from Authorized XM Manufacturers that meet the reasonable requirements of GMs Worldwide Purchasing Organization. Installation of the XM Receivers shall be in accordance with

protection of its Marks. Upon termination or expiration of this Agreement, both parties shall cease all use of the Marks of the other party as soon as practicable, but in any event within thirty (30) days unless the particular media which has
been approved requires a longer lead time, but in no event longer than ninety (90) days.

any challenge to the validity of any other partys Marks, any registrations thereof, or the ownership thereof. Each party will be solely responsible for taking such actions as it deems appropriate to obtain trademark, service mark or copyright
registration for its respective Marks. All uses of or references to the Marks shall inure to the benefit of the respective owner, and all rights with respect to the Marks not specifically granted in this Agreement shall be and are hereby reserved to
the respective owner.

promotional or advertising materials, or items related thereto. If a party desires to sell, or distribute for sale, any of such materials or other merchandising or novelty items bearing the names, trademarks, copyrights or other intellectual
property of any other party, then it shall request permission to do so from the other party, and if granted, the parties shall negotiate in good faith a separate licensing agreement covering such materials or items before they may be sold or

(D) XM IS NOT THE MANUFACTURER OF THE XM RECEIVERS AND XM MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
KIND, NATURE OR DESCRIPTION, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY OR FITNESS OF ANY OF THE XM RECEIVERS FOR ANY PARTICULAR PURPOSE, OR ANY OTHER WARRANTY REGARDING THE DESIGN, CONDITION, CAPABILITY OR
PERFORMANCE OF THE XM RECEIVERS, AND XM HEREBY DISCLAIMS THE SAME. XM shall not be responsible for any loss or damage resulting from any defect of or in the XM Receivers, latent or otherwise, or resulting from any failure of the XM Receivers to
operate or faulty operation of the XM Receivers, nor for any direct, indirect, consequential, incidental or other similar damage (including lost profits) resulting from the transportation, installation, service, operation or use of the XM Receivers,
and shall not be responsible for any such loss or damage resulting from the maintenance or repair of the XM Receivers. Rather, warranty claims relating to XM Receivers installed in GM Vehicles shall be handled by the Authorized XM Manufacturers, in
accordance with Distributor's standard practices with suppliers. In addition, XM shall not be responsible for any breach of any Authorized XM Manufacturer's warranties, indemnities or supply agreements, and no breach thereof shall affect the
limitation on liabilities, rights and obligations of the Parties set forth in this Agreement.

(b) XM and Distributor shall each indemnify,
defend and forever hold harmless the other, the other's affiliated companies and each of the others (and the others affiliated companies) respective present and former officers, shareholders, directors, employees, partners and
agents (Distributor Indemnitees and XM Indemnitees, respectively), against and from any and all losses, liabilities, claims, costs, damages and expenses, including, without limitation, fines, forfeitures, attorneys
fees, disbursements and court or administrative costs (collectively, Costs), arising out of any breach of any term of this Agreement or any warranty, covenant or representation contained herein.

(i) XM Indemnification.

(A) If any
Distributor Indemnitee is charged with infringement of a third partys intellectual property rights, including patent, trademark, copyright, industrial design right, or other proprietary right, or misuse or misappropriation of trade secret
rights, as a result of the installation, use, sale, offer for sale or import of XM Receivers in or for use in GM Vehicles, and if such alleged infringement arises in any way from an aspect or function of the XM Receiver that meets a requirement or
specification of XM for receipt of the XM Service by the XM Receiver, XM will, at no expense to Distributor: (i) defend, hold harmless and indemnify the Distributor Indemnitees against any Costs relating to such charge or claim, including, but
not limited to, Costs for past infringement; and (ii) to the extent appropriate, either, (A) procure for Distributor the right to continue the installation, use, sale, offer for sale or import of XM Receivers in GM Vehicles, or
(B) procure for Distributor the availability of XM Receivers with a modified design such that XM Receivers no longer infringe, provided that such modification can be done without substantially impairing its functionality or performance.



- 22 -



---

(B) With respect to claims arising under this Section 9(b)(i), Distributor will promptly notify XM
in writing of any claim of infringement or indemnification and will provide XM with the authority, information and assistance necessary to defend or settle such claim; provided, however, that Distributor will have the right to participate in such
defense and to approve any proposed settlement in advance. Distributor will have the right to take over from XM the defense of a claim at any time, provided that Distributor releases XM in writing from any further obligation of defense or
indemnification in connection with such claim unless otherwise mutually agreed.

(C) The obligations of XM and Distributor under this
Section 9(b)(i) will survive termination of this Agreement with respect to XM Receivers installed in GM Vehicles.

(ii) A Party
claiming indemnity under this Section 9 must give the indemnifying party prompt notice of any claim, and the indemnifying party shall have the right to assume the full defense of any claims to which its indemnity applies. The indemnified party,
at the indemnifying partys cost, will cooperate fully with the indemnifying party in such defense of any such claim. If the indemnified party compromises or settles any such claim without the prior written consent of the indemnifying party,
then the indemnifying party shall be released from its indemnity obligations with respect to the claim so settled.

(c) The
representations, warranties and indemnities contained in this Section 9 shall continue throughout the Term and the indemnities shall survive the termination of this Agreement, regardless of the reason for such termination.

10. FORCE MAJEURE:

No Party shall have any rights against
another Party for the non-operation of facilities, the non-furnishing of the XM Service, or its inability to perform its terms and obligations under this Agreement if such non-operation, non-furnishing or inability is due to an act of God or other
cause beyond such Partys reasonable control, including, but not limited to, the occurrence of a Regulatory Force Majeure Event.

11. NOTICES:

Any notice or report given under this Agreement shall be in writing, shall be sent postage prepaid by certified mail, return receipt

13. LOAN AND TERMS OF PAYMENT

(a) Loan Commitment.

(i) Advances. Subject to the terms of this Agreement, the Lender agrees
to make advances (each, an Advance, collectively, the Advances) to XM during the Commitment Period in an aggregate principal amount not to exceed the Loan Commitment.

(ii) Purpose. XM shall use the Advances solely to finance payment obligations required under the terms of this Agreement, including Sections
4(b)(Installation Commission), 4(c)(Subscriber Incentive), and 4(d)(Revenue Share) of this Agreement (the Credit Facility Permitted Uses), from time to time owing by XM in cash to GM.

(b) Manner of Borrowing

(i) XM may
request an Advance by delivering to Lender a completed Request for Advance in the form attached hereto as Exhibit A (a Request for Advance) not later than 3:00 p.m., New York City time at least one business day prior to the date such
Advance is to be funded. If at the date of such Request for Advance XM shall not previously have executed the Second Lien Security Agreement and recorded financing statement(s) with the appropriate offices of the Secretary of State as may be
required to effect and perfect the Future Security Interest in accordance with Section 13(g), XM shall as a condition of such Advance execute the Second Lien Security Agreement and record the financing statement(s) as may be required to effect
and perfect the Future Security Interest. Such Request for Advance shall be signed by an authorized officer of XM and shall indicate the amount of the requested Advance, a description of the Credit Facility Permitted Uses for which such Advance is
being requested, and the date for such Advance, which shall be the date on which the Credit Facility Permitted Uses being funded by such Advance shall become due and owing (the Funding Date). If XM is effecting the Future Security
Interest in connection with such Request for Advance, as a condition of funding the Advance, Lender shall have received a certificate of the Chief Financial Officer, the Treasurer or any Assistant Treasurer of XM, dated the date of the Advance
certifying (i) that the Second Lien Security Agreement has been entered into by XM; (ii) that the necessary financing statement(s) have been recorded in the appropriate offices; (iii) that the Future Security Interest is junior only
to the security interests securing the New Credit Facility and other Permitted Indebtedness; (iv) there is no Default or Event of Default under this Agreement; and (v) that XM continues to be obligated to make payments under this
Agreement. Each Request for Advance shall be irrevocable and effective only upon receipt by the Lender.

(ii) Funding. The Lender
shall make each Advance on the date requested by making a notation on its books of account (or, if applicable, the books of account of OnStar) that the Credit Facility Obligations due and owing by XM on the date of the Advance have been paid in an
amount equal to the amount of the Advance.

(c) Interest.

(i) Interest Accrual. Interest shall accrue at the Interest Rate on a daily basis during each Interest Period on the unpaid principal amount of all
Advances and shall be payable in arrears on each Interest Payment Date.

(ii) Default Interest. In the event XM shall fail to make
any payment of the principal or interest when due, after giving effect to any applicable grace period provided for in this Agreement, XM shall pay interest on such unpaid amount, payable from time to time on demand, from the date such amount shall
have become due to the date of payment thereof (after as well as before judgment), accruing on a daily basis, at a per annum rate equal to the sum of the Interest Rate in effect at such time plus one percent (1.0%).



- 25 -



---

(d) Payments and Notes.

(i) Form of Payment. Each payment of principal or interest will be made to the Lender by certified or bank cashiers check or wire transfer of
immediately available funds, at such address or to such account as the Lender specifies in writing to XM at least five (5) Business Days before such payment is to be made.

(ii) Application of Insufficient Payments. If at any time insufficient funds are received by and available to the Lender to pay fully all amounts
of principal and interest, due hereunder, such funds shall be applied (i) first, to pay interest due hereunder, and (ii) second, to pay principal then due hereunder.

(iii) Promissory Note. The Lender may request that the Advances be evidenced by a promissory note. In such event, XM shall prepare, execute and
deliver to the Lender a promissory note payable to the Lender and in a form approved by the Lender. In the event that such a note is issued, XM will pay all sums becoming due hereunder for interest or principal, without the presentation or surrender
of such note or the making of any notation thereon, except that if the such note is paid in full, following such payment, the such note shall be surrendered to XM for cancellation.

(e) Payment at Maturity. The outstanding principal amount of all Advances, together with any accrued interest thereon, shall be due and payable in
full in immediately available U.S. Dollars on the earlier of: (i) the Maturity Date, or (ii) such earlier date as the Advances become due and payable pursuant to this Agreement.

(f) Prepayment.

(i) Optional
Prepayment. The Advances, including all accrued interest thereon, may be prepaid in whole or in part at any time, without premium or penalty; provided that XM shall give the Lender not less than one (1) Business Days written notice
prior to making such prepayment, specifying the amount to be prepaid and the date of prepayment. Each such notice of prepayment shall be irrevocable upon receipt by the Lender. Any Advances prepaid pursuant to this Section 13(f) shall not
reduce the Loan Commitment and, within the limits of such Loan Commitment, amounts of Advances so prepaid may be reborrowed pursuant to Section 13(a) hereof.

(ii) Mandatory Prepayments.

(A) XM shall, on or before March 31st of each calendar year,
prepay all or part of the amount of any outstanding Advances, including all accrued interest thereon, without premium or penalty, in an amount equal to the lesser of (x) fifty percent (50%) of Excess Cash for the fiscal year most recently
then ended, and (y) the amount necessary to prepay the Credit Facility Obligations in full.



- 26 -



---

(B) In the event that XM or Holdings shall, directly or indirectly, consolidate or merge with or into
another entity (whether or not XM or Holdings is the surviving corporation), or sell, assign, transfer, convey or otherwise dispose of all or substantially all of its properties or assets, in any such case, other than in connection with a Parent
Company Merger or a consolidation or merger permitted under Section 13(j)(ii) hereof or under any Agreement Guarantee, then the Advances shall be immediately prepaid in whole, including all interest thereon, without premium or penalty. For the
avoidance of doubt, consolidation with or into another entity (whether or not XM or Holdings is the surviving corporation) means a corporate consolidation and not a consolidation under Generally Accepted Accounting Principles.

(C) In the event the New Credit Facility is terminated by the lender or by XM prior to the expiration thereof and not replaced with a New Credit
Facility involving commitments or aggregate debt financing (as applicable) of at least $250 million with a commitment period or term (as applicable) that extends until or beyond December 31, 2009, then the Advances shall be immediately prepaid
in whole, including all interest thereon, without premium or penalty.

(iii) Loan Commitment Termination.

(A) Any amounts prepaid pursuant to Section 13(f)(ii) shall permanently reduce the Loan Commitment by an equal amount and may not be reborrowed.

(B) In the event that XM or Holdings shall, directly or indirectly, consolidate or merge with or into another entity (whether or not XM
or Holdings is the surviving corporation), or sell, assign, transfer, convey or otherwise dispose of all or substantially all of its properties or assets, in any such case, other than in connection with a Parent Company Merger or a consolidation or
merger permitted under Section 13(j)(ii) hereof or under any Agreement Guarantee, then the Loan Commitment shall terminate with immediate effect. For the avoidance of doubt, consolidation with or into another entity (whether or not XM or
Holdings is the surviving corporation) means a corporate consolidation and not a consolidation under Generally Accepted Accounting Principles.

(iv) No Further Advances.

(A) If the New Credit Facility has not been extended for the period beginning May 5, 2009
until or beyond December 31, 2009, or has not been replaced with a New Credit Facility involving commitments or aggregate debt financing (as applicable) of at least $250 million with a commitment period or term (as applicable) that extends
until or beyond December 31, 2009, then for such time following May 5, 2009 that XM does not have a New Credit Facility, XM shall not be permitted (i) to request further Advances and (ii) assuming a Second Lien Security Agreement
is in place, to grant purported first priority liens (other than Permitted Liens as defined in the New Credit Facility from time to time and/or the grant of a first lien in favor of the lenders under the New Credit Facility in accordance
with the terms of the Second Lien Security Agreement). Any Advances made to XM prior to such a period shall be permitted to remain outstanding until required to be repaid under this Section 13.



- 27 -



---

(B) If the New Credit Facility is terminated by the lender or by XM prior to the expiration thereof and
is not replaced with a New Credit Facility involving commitments or aggregate debt financing (as applicable) of at least $250 million, then for such time that XM does not have a New Credit Facility, XM shall not be permitted to request further
Advances.

(g) Collateral.

(i) Second Lien Security Agreement. Upon the occurrence of a Second Lien Triggering Event, Lender shall be granted, and XM and Lender agree to enter into the Second Lien Security Agreement to effect a security interest in favor of
Lender to secure any and all Advances (whether made at the time of the Second Lien Triggering Event or subsequently) that is the same as but subordinated to the security interest in favor of the lenders under the New Credit Facility and that is the
same as but subordinated to (in the case of first liens) or pari passu with (in the case of second liens) other Permitted Indebtedness, which subordination shall be effected by the Second Lien Intercreditor Agreement or other subordination agreement
in favor of the lenders under the New Credit Facility upon terms satisfactory to the creditors under the New Credit Facility (the Future Security Interest). In the event that any Subsidiary of XM becomes required to become a Subsidiary
Guarantor pursuant to Section 13(j) hereof, such Subsidiary shall, as promptly as practicable following such occurrence, become party to the Second Lien Security Agreement in accordance with the provisions thereof. The Lender, by its acceptance
hereof, consents and agrees to the terms of the Second Lien Security Agreement and the Second Lien Intercreditor Agreement (including, without limitation, the provisions providing for foreclosure and release of collateral), as the same may be in
effect from time to time in accordance with its terms, and authorizes and directs the lenders under the New Credit Facility, the Collateral Agent (as defined in the Second Lien Intercreditor Agreement) or other collateral agent to the extent any is
named to enter into the Second Lien Security Agreement or the Second Lien Intercreditor Agreement and to perform its obligations and exercise its rights thereunder in accordance therewith. XM shall do or cause to be done all such acts and things as
may be required by the provisions of the Second Lien Security Agreement, when entered into, to assure and confirm to the Lender and any collateral agent the security interests in the collateral contemplated hereby and thereby, as from time to time
constituted, so as to render the same available for the security and benefit of this Agreement, according to the intent and purposes herein and therein expressed.

(ii) Release of Collateral. After the Second Lien Security Agreement is entered into, collateral may be released only in accordance with the terms of the Second Lien Security Agreement and the Second Lien
Intercreditor Agreement.

(iii) Release of Security Interest. Upon the payment and satisfaction in full of all Credit Facility
Obligations of XM under this Section 13 and termination of the Loan Commitment, the Lender shall, at the request of XM, promptly deliver a certificate to the lenders under the New Credit Facility, the Collateral Agent (as defined in the Second
Lien Intercreditor Agreement) or other collateral agent to the extent any is named stating that such Credit Facility Obligations have been paid in full and such Loan Commitment has been terminated, and instruct the same to release all rights and
interests of the Lender with respect to the Liens under the Second Lien Security Agreement.

satisfied on or prior to the Funding Date with respect to such Advance:

Material Subsidiaries), whether such Indebtedness or guarantee now exists, or is created after the date hereof, which default results in the acceleration of such Indebtedness prior to its express maturity or is caused by a failure to pay principal
of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a Payment Default) and, in each case, the principal amount of such
Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $25,000,000 or more;

(E) a final nonappealable judgment or final nonappealable judgments for the payment of money are entered by a court or courts of competent jurisdiction

and the order or decree remains unstayed and in effect for 60 consecutive days;

(H) at any time after the Second Lien Security Agreement is entered into and before the security interest is terminated thereunder in accordance with
Section 13(g)(iii), a Borrower or any Material Subsidiary shall breach any material representation, warranty or agreement set forth in the Second Lien Security Agreement or shall repudiate any of its obligations under Second Lien Security

the end of the calendar year in which notice is provided. Each party shall provide reasonable and timely support to allow completion of the audit within the planned timeframe. In the event support is withheld or is not timely, the period to complete

shall survive the execution and delivery of this Agreement. This Agreement may not be modified except in a writing executed by the Parties hereto. Any waiver of any provision of this Agreement must be in writing and signed by the Party whose rights
are being waived. No waiver of any breach of any provision hereof shall be or be deemed to be a waiver of any preceding or subsequent breach of the same or any other provision of this Agreement. The failure of a Party to enforce or seek enforcement
of the terms of this Agreement following any breach shall not be construed as a waiver of such breach. All remedies, whether at law, in equity or pursuant to this Agreement shall be cumulative.

---

(f) Disputes and Interpretation. In the event of any dispute or question of interpretation under
provisions of Sections 2-12 of this Agreement, each of the parties agrees that prior to commencing any legal action in any court of competent jurisdiction, it shall first refer the matter for review and consideration by the parties respective
operating executives, who shall initially be (i) on behalf of Distributor, the GM Executive Director, Satellite Radio Services or his or her delegate and (ii) on behalf of XM, the Executive Vice President of Sales, Marketing and Customer
Service or his or her delegate. In the event that such operating executives fail to resolve the dispute or question of interpretation within 30 days of the matter being referred to them, then the parties shall be free to pursue judicial action
in a court of competent jurisdiction.

(g) Relationship. Neither of XM or Holdings on the one hand, or GM, on the other, shall be,
or hold itself out as, the agent of the other or as joint venturers under this Agreement.

(h) Severability. The holding of any
provision of this Agreement to be invalid or unenforceable by a court of competent jurisdiction shall not affect any other provision of this Agreement, which shall remain in full force and effect. If any provision of this Agreement shall be declared
by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced in whole or in part, such provision shall be interpreted so as to remain enforceable to the maximum extent permissible consistent with applicable law and the
remaining conditions and provisions or portions thereof shall nevertheless remain in full force and effect and enforceable to the extent they are valid, legal and enforceable, and no provisions shall be deemed dependent upon any other covenant or
provision unless so expressed herein.

(i) No Inference Against Author. Each of the Parties acknowledges that this Agreement was
fully negotiated by the Parties and, therefore, no provision of this Agreement shall be interpreted against any Party because such Party or its legal representative drafted such provision.

(j) No Third Party Beneficiaries. The provisions of this Agreement are for the exclusive benefit of the Parties hereto and their permitted
assigns, and no third party shall be a beneficiary of, or have any rights by virtue of, this Agreement.

(k) Headings. The titles
and headings of the sections in this Agreement are for convenience only and shall not in any way affect the interpretation of this Agreement. The language used in this Agreement will be deemed to be the language chosen by the parties to express
their mutual intent, and no rules of strict construction will be applied against any party. Any reference in this Agreement to a Section or Attachment shall, unless the context expressly requires otherwise, be a reference to
a Section in, or an Attachment to, this Agreement. The word including as used herein shall not be construed so as to exclude any other thing not referred to or described.

(l) Non-Recourse. Notwithstanding anything contained in this Agreement to the contrary, it is expressly understood and agreed by the Parties
hereto that each and every representation, warranty, covenant, undertaking and agreement made in this Agreement was not made or intended to be made as a personal representation, undertaking, warranty, covenant, or agreement on the part of any
individual, and any recourse, whether in common law, in equity, by statute or otherwise, against any individual is hereby forever waived and released.

Exhibit B

Form of Agreement Guarantee for Subsidiary Guarantor

This Agreement Guarantee is delivered by the
undersigned (the Subsidiary Guarantor) pursuant to the Third Amended and Restated Distribution and Credit Agreement dated as of
, 2008 among XM Satellite Radio Inc., XM Satellite Radio Holdings Inc. and General Motors
Corporation (the Agreement). Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Agreement.

For value received, the Subsidiary Guarantor hereby fully and unconditionally guarantees to the Lender that: (a) the principal amount of, and premium and interest on, the Advances will be duly and punctually paid in full when due,
whether at maturity, by acceleration or otherwise, and interest on overdue principal and premium amount and (to the extent permitted by law) interest on any interest, if any, on the Advances and all other obligations of XM to the Lender under the
Agreement (including fees, expenses or other) will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of the Advances or any of such other
obligations the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at the Maturity Date, by acceleration or otherwise.

The Subsidiary Guarantor, and by its acceptance hereof, the Lender, hereby confirms that it is the intention of such parties that the guarantee by such
Subsidiary Guarantor pursuant to this Agreement Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or
state law. To effectuate the foregoing intention, the Lender and the Subsidiary Guarantor hereby irrevocably agree that the obligations of the Subsidiary Guarantor under this Agreement Guarantee shall be limited to the minimum extent necessary to
ensure that, after giving effect to all other contingent and fixed liabilities of the Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the
obligations of such other Subsidiary Guarantor under this Agreement Guarantee, the obligations of the Subsidiary Guarantor under this Agreement Guarantee do not constitute a fraudulent transfer or conveyance under applicable law.

Failing payment when due of any amount so guaranteed or failing performance of any other obligation of XM to the Lender, for whatever reason, the
Subsidiary Guarantor will be obligated to pay or to perform or to cause the performance of, the same immediately without the necessity of any action by the Lender. An Event of Default under Section 13(i) of the Agreement shall constitute an
event of default under this Agreement Guarantee, and shall entitle the Lender to accelerate the obligations of the Subsidiary Guarantor hereunder in the same manner and to the same extent as the obligations of XM.

The Subsidiary Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability
of the Agreement, the absence of any action to enforce the same, any waiver or consent by the Lender with respect to any thereof, the entry of any judgment against XM, any action to enforce the same or any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of the Subsidiary Guarantor.

The Subsidiary Guarantor hereby waives and
relinquishes: (a) any right to require the Lender to proceed against XM, the Parent Guarantor any other Subsidiary Guarantor or any other Person or to proceed against or exhaust any security held by or on behalf of the Lender at any time or to
pursue any other remedy in any secured partys power before proceeding against the Subsidiary Guarantor; (b) any defense that may arise by reason of the incapacity, lack of authority, death or disability of any other Person or Persons or
the failure of the Lender to file or enforce a claim against the estate (in administration, bankruptcy or any other proceeding) of any other Person or Persons; (c) demand, protest and notice of any kind, including but not limited to notice of
the existence, creation or incurring of any new or additional Indebtedness or obligation or of any action or non-action on the part of the Subsidiary Guarantor, XM, the Lender, any creditor of the Subsidiary Guarantor or on the part of any other
Person whomsoever in connection with any obligations the performance of which are hereby guaranteed; (d) any defense based upon an election of remedies by the Lender, including but not limited to an election to proceed against the Subsidiary
Guarantor for reimbursement; (e) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (f) any
defense arising because of the Lenders election, in any proceeding instituted under the United States Bankruptcy Code (the Bankruptcy Code), of the application of Section 1111 (b)(2) of the Bankruptcy Code; and
(g) any defense based on any borrowing or grant of a security interest under Section 364 of the Bankruptcy Code.



---

The Subsidiary Guarantor hereby covenants that this Agreement Guarantee will not be discharged except by
payment in full of all principal and interest on the Advances and all other costs provided for under the Agreement, or as provided in Section 13(j)(iii) of the Agreement.

If the Lender is required by any court or otherwise to return to either XM or the Subsidiary Guarantor, or any custodian, trustee, or similar official
acting in relation to XM or the Subsidiary Guarantor, any amount paid by XM or the Subsidiary Guarantor to the Lender, this Agreement Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. The Subsidiary
Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Lender in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby.

The Subsidiary Guarantor agrees that, as between it, on the one hand, and the Lender, on the other hand, (x) the maturity of the obligations
guaranteed hereby may be accelerated as provided in Section 13(i) of the Agreement for the purposes hereof, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby,
and (y) in the event of any acceleration of such obligations as provided in Section 13(i) of the Agreement, such obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantor for the
purpose of this Agreement Guarantee.

The Subsidiary Guarantor hereby acknowledges that it shall not consolidate or merge with or into a
corporation or any other entity other than XM or another Subsidiary Guarantor (whether or not affiliated with the Subsidiary Guarantor), or transfer all or substantially all of its assets to a corporation or any other entity other than XM or another
Subsidiary Guarantor (whether or not affiliated with the Subsidiary Guarantor), unless this Agreement Guarantee shall be expressly assumed (in the event that the Subsidiary Guarantor is not the surviving corporation in the merger) or a new Agreement
Guarantee shall be signed by such successor corporation or other entity and delivered to the Lender. Any Agreement Guarantee so issued shall in all respects have the same legal rank and benefit under the Agreement as any Agreement Guarantee
theretofore and thereafter issued in accordance with the terms of the Agreement as though all of such Agreement Guarantees had been issued at the date of the execution thereof.

This Agreement Guarantee shall be governed by and construed in accordance with the laws of the State of New York.

IN WITNESS WHEREOF, the undersigned Subsidiary Guarantor has caused this Agreement Guarantee to be duly executed as of
, 200.
