(c)                    any circumstances which might otherwise constitute a defense available to, or discharge of, Oglethorpe with respect to this Agreement, any of the Operative Documents, any of the AMBAC Surety Documents or any of the other Surety Bond Documents or any other instrument, document or agreement;

(d)                   whether or not any of the acts mentioned in any of the provisions of this Agreement, any of the Operative Documents, any of the AMBAC Surety Documents or any of the other Surety Bond Documents or any other instrument, document or agreement referred to herein or therein shall be done or omitted;

(e)                    whether the maturity of any Covered Obligations shall be accelerated, or any Covered Obligations shall be modified, supplemented or amended in any respect, or any right under any of the Operative Documents, the Surety Bond Documents, the AMBAC Surety Documents or any other instrument, document or agreement referred to herein or therein shall be waived or any other guarantee for any Covered Obligations or any security therefor shall be released or exchanged in whole or in part or otherwise dealt with;
