If the debtor under a debtor-creditor-supplier agreement falling within section 12(b) or (c) has, in relation to a transaction financed by the agreement, any claim against the supplier in respect of a misrepresentation or breach of contract, he shall have a like claim against the creditor, who, with the supplier, shall accordingly be jointly and severally liable to the debtor.

Subject to any agreement between them, the creditor shall be entitled to be indemnified by the supplier for loss suffered by the creditor in satisfying his liability under subsection (1), including costs reasonably incurred by him in defending proceedings instituted by the debtor.

This section applies notwithstanding that the debtor, in entering into the transaction, exceeded the credit limit or otherwise contravened any term of the agreement.

In an action brought against the creditor under subsection (1) he shall be entitled, in accordance with rules of court, to have the supplier made a party to the proceedings.
