490. Extension of time under notice to remedy after notice to quit.

Where a notice to quit is stated to be by reason of the tenant's1 failure to remedy a breach of any term or condition of his tenancy within the time specified in the notice to remedy2 or within that time as extended3, and it appears to the arbitrator4 that, notwithstanding that the time originally specified was reasonable, it would have been unreasonable to require the tenant to remedy the breach within that time5, then the arbitrator may treat the time as having been extended or further extended and may make his award as if the time had not expired6.
