(1) Obtain a fully completed exemption certificate from the purchaser, taken in good faith which means that the seller obtained a certificate that claims an exemption that:

(a) Was statutorily available on the date of the transaction in the jurisdiction where the transaction is sourced;

(b) May be applicable to the item being purchased; and

(c) Is reasonable for the purchaser's type of business; or
