 - When you call an *exit()* function from a notebook interactively, the Fabric notebook throws an exception, skips running subsequent cells, and keeps the Spark session alive.

+- When you orchestrate a notebook in a pipeline that calls an *exit()* function, the notebook activity returns with an exit value, completes the pipeline run, and stops the Spark session. Do not enclose the *exit()* function around a try/catch as this NotebookExit Exception must propagate for the pipeline to get the return value.
 
 - When you call an *exit()* function in a notebook that is being referenced, Fabric Spark will stop the further execution of the referenced notebook, and continue to run the next cells in the main notebook that calls the *run()* function. For example: Notebook1 has three cells and calls an *exit()* function in the second cell. Notebook2 has five cells and calls *run(notebook1)* in the third cell. When you run Notebook2, Notebook1 stops at the second cell when hitting the *exit()* function. Notebook2 continues to run its fourth cell and fifth cell.
