DB's allowed claim will (if the settlement agreement is approved in California) be in the same creditor class as the senior noteholders.
If money is distributed to that class, it will be shared pro rata based on the amount of the allowed claims of each member of that class.
This is absolutely the simple and standard methodology that applies to creditor distributions in FDIC receiverships and in bankruptcy proceedings.
