A small agreement is—
being an agreement which is either unsecured or secured by a guarantee or indemnity only (whether or not the guarantee or indemnity is itself secured).
For the purposes of paragraph (a) of subsection (1), running-account credit shall be taken not to exceed the amount specified in that paragraph if the credit limit does not exceed that amount.
Where—
this Act applies to the small agreements as if they were regulated agreements other than small agreements.
If, apart from this subsection, subsection (3) does not apply to any agreements but would apply if, for any party or parties to any of the agreements, there were substituted an associate of that party, or associates of each of those parties, as the case may be, then subsection (3) shall apply to the agreements.
