If you just directly attached this to a dummy pot of $120k, you'd have a $1k/month annuity at age 55 for $288k, which is already 4.2%. It also comes with the significant bonus that your estate keeps the $168k, plus what's left of the $120k, if you die before 65.
So basically, I just think there are much better annuities out there than what you found.
