15 U.S.C. § 77ooo — Duties and responsibility of the trustee

**(a) Duties prior to default** The indenture to be qualified shall automatically be deemed (unless it is expressly provided therein that any such provision is excluded) to provide that, prior to default (as such term is defined in such indenture)— (1) the indenture trustee shall not be liable except for the performance of such duties as are specifically set out in such indenture; and (2) the indenture trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, in the absence of bad faith on the part of such trustee, upon certificates or opinions conforming to the requirements of the indenture; but the indenture trustee shall examine the evidence furnished to it pursuant to [section 77nnn of this title](https://uscode.house.gov/view.xhtml?req=granuleid:USC-prelim-title15-section77nnn&num=0&edition=prelim) to determine whether or not such evidence conforms to the requirements of the indenture. **(b) Notice of defaults** The indenture trustee shall give to the indenture security holders, in the manner and to the extent provided in subsection (c) of [section 77mmm of this title](https://uscode.house.gov/view.xhtml?req=granuleid:USC-prelim-title15-section77mmm&num=0&edition=prelim), notice of all defaults known to the trustee, within ninety days after the occurrence thereof: Provided, That such indenture shall automatically be deemed (unless it is expressly provided therein that such provision is excluded) to provide that, except in the case of default in the payment of the principal of or interest on any indenture security, or in the payment of any sinking or purchase fund installment, the trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee, or a trust committee of directors and/or responsible officers, of the trustee in good faith determine that the withholding of such notice is in the interests of the indenture security holders. **(c) Duties of the trustee in case of default** The indenture trustee shall exercise in case of default (as such term is defined in such indenture) such of the rights and powers vested in it by such indenture, and to use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. **(d) Responsibility of the trustee** The indenture to be qualified shall not contain any provisions relieving the indenture trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that— (1) such indenture shall automatically be deemed (unless it is expressly provided therein that any such provision is excluded) to contain the provisions authorized by paragraphs (1) and (2) of subsection (a) of this section; (2) such indenture shall automatically be deemed (unless it is expressly provided therein that any such provision is excluded) to contain provisions protecting the indenture trustee from liability for any error of judgment made in good faith by a responsible officer or officers of such trustee, unless it shall be proved that such trustee was negligent in ascertaining the pertinent facts; and (3) such indenture shall automatically be deemed (unless it is expressly provided therein that any such provision is excluded) to contain provisions protecting the indenture trustee with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the holders of not less than a majority in principal amount of the indenture securities at the time outstanding (determined as provided in subsection (a) of [section 77ppp of this title](https://uscode.house.gov/view.xhtml?req=granuleid:USC-prelim-title15-section77ppp&num=0&edition=prelim)) relating to the time, method, and place of conducting any proceeding for any remedy available to such trustee, or exercising any trust or power conferred upon such trustee, under such indenture. **(e) Undertaking for costs** The indenture to be qualified shall automatically be deemed (unless it is expressly provided therein that any such provision is excluded) to contain provisions to the effect that all parties thereto, including the indenture security holders, agree that the court may in its discretion require, in any suit for the enforcement of any right or remedy under such indenture, or in any suit against the trustee for any action taken or omitted by it as trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorney’s fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant: Provided, That the provisions of this subsection shall not apply to any suit instituted by such trustee, to any suit instituted by any indenture security holder, or group of indenture security holders, holding in the aggregate more than 10 per centum in principal amount of the indenture securities outstanding, or to any suit instituted by any indenture security holder for the enforcement of the payment of the principal of or interest on any indenture security, on or after the respective due dates expressed in such indenture security.
