* If the Registrant does not sign controlled substance orders, he/she does not need to enroll in CSOS. However, he/she must delegate a Principal Coordinator if any individuals are to enroll in CSOS.

** If the Registrant signs controlled substance orders, he/she may choose to be the Principal Coordinator. If this is the case, the Registrant will submit only form 251 and not form 252. If the Registrant chooses to be the Principal Coordinator, no other applicant may apply as Principal Coordinator.
