If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the outstanding Notes may declare the Notes to be due and payable immediately. Noteholders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, holders of a majority in principal amount of the outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from the notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice is in Noteholders' interest.
