If a premature termination codon is created within the second-to-last exon and is very close to the end of that exon, the protein transcription machinery (ribosomes) will still remove the exon-junction complex that connects the second-to-last exon to the last exon ensuring that the RNA won’t be degraded by the surveillance machinery. We treat premature termination codons within the last 15 codons of the second-to-last exon in the same way as if they were in the last exon; they are of uncertain significance without additional evidence.
