no link on what exactly the Jazz offered, but you can sort of do the math yourself by reading this article.

"Yahoo Sports’ Adrian Wojnarowski, who first reported the impasse, claimed the sides “never came close on an extension” and that they remained “several million dollars apart” when calling talks off.
Hayward’s side was reportedly hoping to secure more than Favors’ salary but somewhere less than the $80 million maximum deal fellow 2010 draftee Paul George received this offseason."
So if Hayward wanted more than Favors, that means he wanted around $12-13M, "several million apart" would mean the Jazz offered $9-10M.
