Proprietary lock-in.

This phrase from Appendix A tells you all you need to know about the 
patent licensing: "on fair, reasonable, and non-discriminatory terms". 
If the FRAND patent model worked, the mobile phone and tablet industry 
would be a happy garden of mutual innovation, rather than a dismal swamp 
of litigation.

The broad exceptions in Item 3 of Option 2 tells you that anything you 
create *will* be deemed infringing, because you'll be innovating in a 
related field that's not covered by the FRAND license. The only question 
will be whether you have enough money to make you a worthwhile target.

I. Am. Not. A. Lawyer.
