the Optionee has not, within 60 days following delivery of such notice of default, cured such default or commenced proceedings to cure such default by appropriate payment or performance, the Optionee hereby agreeing that should it so commence to cure any default it will prosecute the same to completion without undue delay.

Should the Optionee fail to comply with the provision of subparagraph (b), the Optionor may thereafter terminate this Agreement by giving notice thereof to the Optionee, always provided that the default in question has not been cured or substantially cured at the time of the Optionee giving such notice of termination.
