Notice of Default
The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default unless the Administrative Agent shall have received written notice thereof from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating such notice is a “Notice of Default.” In the event that the Administrative Agent receives such a notice, the Administrative Agent shall promptly give notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders, provided that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action or give such directions, or refrain from taking such action or giving such directions, with respect to such Default or Event of Default as it shall deem to be in the best interests of the Lenders.

. Notice of Default. If a Default occurs and is continuing with respect to a series of Debt Securities and if such Default is known to a Responsible Officer of the Trustee, the Trustee shall mail to each Holder of a Debt Security of such series a notice of such Default within 90 days (or such shorter period as may be required by applicable law) after such Default occurs. Except in the case of a Default in payment of principal of, premium, if any, or interest on any Debt Security, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Debt Securities.
