(2) If consummation of the loan does not occur in a face-to-face transaction between the credit grantor and the borrower, the credit grantor may delay delivering a copy of the agreement, note, or other evidence of the loan to the borrower until the due date of the first payment. (b) If there is more than one borrower, a copy of the agreement, note, or other evidence of the loan may be delivered to any borrower who is primarily liable on the loan. (c) Written acknowledgment by a borrower of delivery made in accordance with this section of a copy of the agreement, note, or other evidence of the loan is conclusive proof of the delivery as between the borrower and any assignee of the agreement, note, or other evidence of the loan without actual knowledge to the contrary.
