BSE, CHX, MS4X, NSX, PHLX and more? NYSE & NASDAQ aren't the only players in the US equities exchange market. NYSE & NASDAQ are merely the 2 largest players in a very large field. And that's _just_ equities. Get into commodities or options and other derivatives and there's even more.

Also, not being listed on NYSE or NASDAQ doesn't mean you're any less of a reputable company. There's some real shit listed on both.
