A bank may extend and maintain purpose credit without regard to the provisions of this part if such credit is extended:

To any bank;

To any foreign banking institution;

Outside the United States;

To an employee stock ownership plan (ESOP) qualified under section 401 of the Internal Revenue Code (26 U.S.C. 401);

To any plan lender as defined in § 221.4(a) to finance an eligible plan as defined in § 221.4(b), provided the bank has no recourse to any securities purchased pursuant to the plan;

To any customer, other than a broker or dealer, to temporarily finance the purchase or sale of securities for prompt delivery, if the credit is to be repaid in the ordinary course of business upon completion of the transaction and is not extended to enable the customer to pay for securities purchased in an account subject to part 220 of this chapter;

Against securities in transit, if the credit is not extended to enable the customer to pay for securities purchased in an account subject to part 220 of this chapter; or

To enable a customer to meet emergency expenses not reasonably foreseeable, and if the extension of credit is supported by a statement executed by the customer and accepted and signed by an officer of the bank acting in good faith. For this purpose, emergency expenses include expenses arising from circumstances such as the death or disability of the customer, or some other change in circumstances involving extreme hardship, not reasonably foreseeable at the time the credit was extended. The opportunity to realize monetary gain or to avoid loss is not a “change in circumstances” for this purpose.
