The rights, remedies, powers and privileges of a party hereunder are cumulative and not exclusive of any rights or remedies that such party may otherwise have. If an Event of Default is waived by the Purchaser in accordance with this Agreement, then it will cease to exist. If a Default is so waived, then it will be deemed to be cured and any Event of Default arising therefrom will be deemed not to occur. However, no such waiver will extend to any subsequent or other Default or Event of Default or impair any right arising therefrom.
