	However, that none of the events described in the foregoing clauses (i) or (iv) shall constitute Good Reason unless (x) you have notified the Company in writing describing the events which constitute Good Reason within 30 days (the “GR Cure Period”) following the initial existence of the condition, (ii) the Company fails to cure such events within another 30 day Period after the Company’s receipt of such written notice (second “GR Cure Period”) and (iii) you actually terminate employment by the end of the second GR Cure Period.
