(b) Unless subsection (a) applies, the liability of an issuer, nominated person, or adviser for action or omission is governed by the law of the jurisdiction in which the person is located. The person is considered to be located at the address indicated in the person's undertaking. If more than one address is indicated, the person is considered to be located at the address from which the person's undertaking was issued. For the purpose of jurisdiction, choice of law, and recognition of interbranch letters of credit, but not enforcement of a judgment, all branches of a bank are considered separate juridical entities and a bank is considered to be located at the place where its relevant branch is considered to be located under this subsection.
(c) Except as otherwise provided in this subsection, the liability of an issuer, nominated person, or adviser is governed by any rules of custom or practice, such as the uniform customs and practice for documentary credits, to which the letter of credit, confirmation, or other undertaking is expressly made subject. If(i) this article would govern the liability of an issuer, nominated person, or adviser under subsection (a) or (b), (ii) the relevant undertaking incorporates rules of custom or practice, and (iii) there is conflict between this article and those rules as applied to that undertaking, those rules govern except to the extent of any conflict with the nonvariable provisions specified in section 5-103(c).
(d) If there is conflict between this article and articles 3, 4, 4A, or 9, this article governs.
(e) The forum for settling disputes arising out of an undertaking within this article may be chosen in the manner and with the binding effect that governing law may be chosen in accordance with subsection (a).
