1. (a) Subject to section 42a-2A-604 and subsection (b) of this section, delay in performance or nonperformance by the lessor or supplier is not a default under the lease contract if performance as agreed has been made impracticable by:

   1. (1) The occurrence of a contingency the nonoccurrence of which was a basic assumption on which the lease contract was made; or
   2. (2) Compliance in good faith with any applicable foreign or domestic governmental statute, regulation or order, whether or not such statute, regulation or order later proves to be invalid.
2. (b) A party claiming excuse under subsection (a) of this section shall seasonably notify the other party that there will be delay or nonperformance. If a finance lessor claims excuse under subsection (a) of this section, the finance lessor shall seasonably notify both the lessor and the lessee that there will be delay or nonperformance. If the claimed excuse affects only a part of the lessor's or supplier's capacity to perform, the lessor or supplier shall also allocate production and deliveries among its customers in a manner that is fair and reasonable and notify the lessee of the estimated quota made available. In allocating production and deliveries, the lessor or supplier may include regular customers not then under contract as well as its own requirements for further manufacture.
