Item 1.01.

Entry into a Material Definitive Agreement.

~~The~~Senior Secured Term ~~information~~Loan. ~~under~~On ~~Item~~June 826, 2008, XM Satellite Radio Inc.01 and XM Satellite Radio Holdings Inc. entered into a Credit Agreement relating to a $100 million term loan (the “Credit Agreement”) with UBS AG, Stamford Branch, as Administrative Agent and the lenders party thereto. XM used a portion of the loan proceeds to repay the previously disclosed draw under its $150 million GM credit facility. Following this ~~report~~repayment, isXM ~~incorporated~~has byfull ~~reference~~access ~~herein~~to the GM credit facility. On June 26, 2008, the lenders who are party to XM’s $250 million revolving secured facility (the “Original Facility”) entered into a Fourth Amendment to the Original Facility to approve the Credit Agreement (which replaces XM’s right under the Original Facility to elect to increase the size of the Original Facility by $100 million).

~~Item~~The 2Credit Agreement includes market rate syndication and commitment fees, interest and expenses, and, similar to the Original Facility, has a scheduled maturity date of May 5, 2009, will survive if our pending merger with Sirius Satellite Radio is consummated, and is secured by substantially all of XM’s assets other than specified property (on a pari passu basis with the Original Facility).03 ~~Creation~~The Credit Agreement also contains covenants, representations and events of default that are substantially similar to those under the Original Facility. In addition, the Credit Agreement, like the Original Facility, contains a ~~Direct~~financial ~~Financial~~covenant ~~Obligation~~that requires XM to maintain a level of cash and cash equivalents from time to time of either $50 million or an$75 million. If ~~Obligation~~XM does not comply with the various covenants under anthe ~~Off-Balance~~Credit ~~Sheet~~Agreement, ~~Arrangement~~the lenders may, subject to various customary cure rights, require the immediate payment of aall ~~Registrant~~amounts outstanding under the Credit Agreement and foreclose on the collateral.

~~The~~Amendment ~~information~~to ~~under~~Employment ~~Item 8~~Agreement—Chairman.01 Effective June 26, 2008, we entered into an amendment to the employment agreement of ~~this~~Gary ~~report~~Parsons, isour ~~incorporated~~Chairman, byto ~~reference~~extend ~~herein~~the term of the agreement to November 18, 2009. This amendment did not modify any salary, bonus or equity compensation terms. Mr. Parsons’ employment agreement would have expired on June 30, 2008.

Item 82.0103. ~~Other~~Creation ~~Events~~of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

As previously disclosed, our multi-year agreement with Major League Baseball (MLB) requires us to maintain $120 million in escrow for the benefit of MLB or furnish other credit support in such amount. This credit support was previously provided through a surety bond which expires June 30, 2008. On May 16, 2008, we provided $120 million for an escrow arrangement for the benefit of MLB to replace the expiring surety bond. We are continuing to have discussions with MLB about this escrow and related matters and there may be further developments. The ~~escrow~~information ~~funds were from current operating cash and on May 15, 2008, we borrowed the remaining $62.5 million available~~ under ~~our $250~~Item ~~million revolving credit facility with a group of banks~~1.01 ~~This escrow~~is ~~arrangement,~~incorporated ~~which~~herein weby intend to replace with a letter of credit, surety bond or other similar arrangement, reduces the company’s unrestricted cash liquidity, and could have an adverse effect on our financial position if we are not able to replace the escrow arrangement with a letter of credit, surety bond or other similar arrangementreference.

~~Interest~~Item ~~under our revolving credit facility is currently 6~~5.~~00% and is based on the prime rate~~02. ~~All~~Departure ~~amounts~~of ~~drawn~~Directors ~~under~~or ~~the~~Certain ~~facility~~Officers; ~~are~~Election ~~due~~of onDirectors; ~~May 5,~~Appointment ~~2009 and are secured by a lien on substantially all~~ of ~~our~~Certain ~~assets.~~Officers; InCompensatory ~~February~~Arrangements 2008, we executed an amendment to the facility to provide that the facility will survive our pending merger with Sirius Satellite Radio. In addition, we expect to execute an amendment to the facility to provide that the $75 million in cash and cash equivalents we are required to maintain at all times is lowered to $50 million for a period of 90Certain ~~days~~Officers. We continue to have access to the $150 million credit facility provided by General Motors, which may be used only for payments to GM and which matures in December 2009. We expect to begin utilizing the General Motors credit facility in June 2008.

AsThe ~~previously~~information ~~disclosed,~~under provided that we meet the revenue, expense and cash flow projections of our current business plan, we expect to be fully funded and not need additional liquidity to continue operations beyond our existing assets, credit facilities and cash generated by operations; our current business plan is based on estimates regarding expected future costs, expected future revenue and assumes the refinancing or renegotiating of certain of our obligations as they become due, including the maturity of our existing credit facilities and $400Item ~~million of convertible notes in 2009 and the MLB escrow arrangement~~1.01 ~~Our~~is ~~costs~~incorporated ~~may~~herein exceed or our revenues may fall short of our estimates, our estimates may change, and future developments may affect our estimates. Any of these factors may increase our need for funds, which would require us to seek additional (including replacement) financing, which financing may not be available on favorable terms or at all, to continue implementing our current business plan. In addition, we may seek additional financing, such as the sale of additional equity and debt securities, to undertake initiatives not contemplated by ~~our current business plan or for other business reasons, or seek to refinance or renegotiate certain of our other obligations~~reference.

The foregoing description of the amendment to the credit facility does not purport to be complete, and is qualified in its entirety by reference to the full text of the form of amendment to the credit facility, which is incorporated herein by reference.
