"Once notice is given, there are still 7 days when liabilities will be covered by the guarantee - and‚ all liabilities which arise before "notice+7" will still be covered by the guarantee…The critical point is “did the debt arise during the period covered by the guarantee” – not “did we try to claim against the guarantee during the period covered. Future liability is extinguished on cancellation, not past liability"
“…[B]ut such determination shall not affect the liability of the guarantor for the amount due hereunder at the date of expiration of the notice with interest as herein provided until payment in full”
