How are business loans handled when the loaning party dies?

[Account Closed]

So my mother recently passed and she invested several hundred thousand in a friends business and he was paying her a yearly return at 10%. This agreement was in place to last another 5 years. 

So is the remaining 5 years of that agreement still valid or can the estate come after that money?

Is the loan taker obligated to now pay the 10% a year to the estate while it runs its course?

@Kody Digre The agreement controls. If this death does not specifically trigger something (such as acceleration of the debt), then the agreement as written continues to be enforceable by the decedent‘s estate or heirs.
