Yes - your 403(b) distribution qualifies for the $6,000 Arkansas exemption.
You are eligible for the $6,000 exemption for retirement benefits provided the distribution was from public or private employment-related retirement systems, plans, or programs. (The recipient need not be retired.) The method of funding is irrelevant. The exemption may be taken from either lump-sum or installment payments. The early withdrawal penalty may be applicable even though the exemption is granted
