Late last week Sirius agreed to settle two class action lawsuits regarding the merger. The lawsuits sought additional information relating to the valuation of XM, the uncertainty of some of XM's litigation, and the uncertainty about concessions that may be needed to garner merger approval. Subsequent to the deposition of Mel Karmazin last week, the parties agreed to a memorandum of understanding where Sirius and the parties will settle pending court approval.

As part of the settlement, Sirius agreed to disclose additional information, while reserving that the information may not be material, and may not be required under law. The settlement included as filed in an 8K with the SEC:

Supplemental Disclosures Concerning Background of the Merger

On October 24, 2006, Mr. Karmazin briefed the Sirius board of directors on his discussions with XM regarding a possible business combination, summarizing his discussions with Messrs. Parsons and Panero over the past month. Among other things, Mr. Karmazin discussed with the Sirius board of directors regulatory issues involved with a merger, the likely market reaction, and the value creation and synergies that would arise from a business combination. The Sirius board of directors engaged in an extensive discussion of the potential cost savings, including savings in cost centers, research and development and general and other expenses. The board further discussed XM's assets, its relationships with automakers, whether there were other potential bidders for XM, and XM's capital structure. Following this discussion, the Sirius board authorized Mr. Karmazin to continue discussions with XM.

In connection with their due diligence reviews, Sirius and XM instituted procedures to ensure that competitive information that was not legally appropriate to disclose was not exchanged by the management of the companies. In certain cases, management of each company reviewed documents provided by the other company that did not include competitive information; and, in other instances, outside counsel to each company reviewed materials but was not permitted to share competitively sensitive information with their clients. Sirius and Sirius' advisors reviewed, among other things, XM's agreements with automakers (Toyota, Hyundai, Nissan, General Motors, Honda), sports leagues and conferences (MLB, NHL, ACC, Big East, Pac-10), retailers (Wal-Mart, Circuit City, Best Buy), news providers (CNN, Fox News), entertainment content providers (Oprah, Opie & Anthony, Starbucks, ABC/ESPN), technical service providers (Loral, Sea Launch) and radio manufacturers (Delphi).

Sirius' advisors also conducted a due diligence review of XM's litigation and regulatory matters, including but not limited to: (i) the purported stockholder class action captioned In re XM Satellite Radio Sec. Litig., Civ. Act. No. 06-00802 (ESH) (D.C.), which has since been dismissed with prejudice; (ii) an action by members of the recording industry captioned Atlantic Recording Corp., et al., v. XM Satellite Radio, Inc., No. 06-3733 (DAB) (GWG) (S.D.N.Y.); (iii) a purported consumer class action captioned Enderlin v. XM Satellite Radio Holdings, Inc., et al., (E. Dist. Ark.); (iv) proceedings before the Copyright Royalty Board; (v) an arbitration concerning satellite insurance matters; and (vi) various FCC, FTC and SEC inquiries. In connection with these matters, Sirius' advisors reviewed pleadings and court filings, conducted research and received briefings from XM's in-house and outside counsel.

Supplemental Disclosure Concerning Reasons for the Merger

Sirius believes that the merger will result in significant cost synergies. Wall Street equity analysts have published estimates of the present value of cost synergies ranging from $3 billion to $9 billion. Sirius expects operating cost savings to be achievable in almost every cost item on the companies' income statement, including:

º sales and marketing (through, among other things, lower brand advertising expense, cost reductions in retail relationship management, sales training, retail placement monitoring, and ad sales);

º subscriber acquisition (through areas such as lower radio production costs driven by enhanced scale);

º research and development (including through the possible elimination of duplicative R&D efforts with the adoption of technological developments across platforms, and the elimination of overlapping R&D resources);

º general and administrative expenses (through the elimination of redundant staff);

º product development;

º content (through potential improvement in margins given broader audience reach and lower internal programming costs by elimination of certain channel overlap); and

º programming operating infrastructure (as a result of the potential to rationalize maintenance and administrative capital expenditures, and avoid the duplication of disaster recovery expenses).

Moreover, over the long-term, Sirius believes the combined company will derive significant additional value by procuring its future generation satellites and terrestrial repeaters as a single entity and by potentially reducing satellite, engineering and support requirements.

Supplemental Disclosure Concerning the Sirius Board of Directors' Recommendation

The factors and risks considered by the Sirius board of directors in connection with its determination that the merger and entering into the merger agreement with XM are advisable and in the best interest of Sirius and its stockholders, and its approval thereof, also include the probability that other strategic alternatives would fail to provide Sirius' stockholders with the same value, synergies and cost savings as would a business combination with XM.

Sirius paid Morgan Stanley $4,576,000 in connection with Morgan Stanley's services rendered as the administrative and collateral agent under its $250 million senior secured term credit facility. In addition, in the five years preceding the execution of the merger agreement, Sirius paid Morgan Stanley an aggregate of approximately $28,000,000 in connection with the underwriting and placement of various issuances of convertible debt securities and debt securities.

Supplemental Disclosure Concerning Regulatory Approvals Required for the Merger

In response to a "Second Request" for information relating to the merger from the U.S. Department of Justice, Sirius has produced millions of pages of documents from the files of many of its executives. These documents include business planning documents, documents discussing competition in the audio entertainment industry, pricing documents, as well as documents covering numerous other categories. In response to the Second Request, Sirius has also produced data regarding its business operations, including information on revenues, sales, and prices which was requested by the Department of Justice. As part of its investigation and as is typical in Second Request investigations, the Department of Justice has taken deposition testimony and, Sirius understands, has requested information from some third parties, including from Sirius' competitors in audio entertainment. On September 4, 2007, Sirius and XM each certified to the Department of Justice that they were in substantial compliance with the Second Request.
