Lots of issues to consider here!
1. It is typical for a traditional publisher to hold the copyright to the book. A friend of mine who got a traditional publishing deal cannot even quote from her own book on her blog, etc. If holding on to your copyright is important to you, a book deal like this isn't a good choice.
2. Royalties are 10% of what? The book revenue? A royalty share? You better find out what that 10% means.
3. Big deal! If you self publish with Kindle Direct Publishing for print or Kindle eBook, it's available in the U.S. and several international markets.
4. Have an attorney review the "get out of contract" language and understand what that really means. If the publisher terminates, then what happens to your copyrights? You need legal counsel on this.
Hope that gives you some things to think about.
