model the process by BPMN

There are two roles – Worker A and Worker B. Worker A begins with ‘Task A’. When ‘Task A’ is finished Worker A must complete ‘Task B’ and ‘Task C’ in any order (‘Task B’ and ‘Task C’ are parallel tasks). When both are completed Worker A then completes ‘Task D’. During ‘Task C’ a message is sent to Worker B. After Worker B receives the message they begin ‘Task E’. When ‘Task E’ and ‘Task D’ are completed the process is successfully completed.
