It may be Independence Day week, but it appears that there are a number of companies willing to sell their independence to the highest bidder.

• XM SATELLITE RADIO HOLDINGS INC (NASDAQ: XMSR)

Word is that there's more than one bid out for the satellite radio company. We know about the merger agreement with Sirius Satellite Radio Inc's (NASDAQ: SIRI), so who's the other party? Or, is there another party? Some are convinced it's just talk. No names are even floating around. But for XM to walk away from Sirius would cost them a $175M break-up fee. They'd have to really be serious about another offer to do that.


• BUILDING MATERIALS HOLDING CORPORATION (NYSE: BLG)

In May, Robert L .Chapman of Chapman Capital, the "activist investor", said Building Materials Holding Corp. should consider selling all or parts of itself. Then he upped his stake to 8.1% in the residential construction services provider. Now comes word that the company may have hired, or be in the process of hiring, a strategic advisor.
