# §77rrr. Effect of prescribed indenture provisions

- (a) **Imposed duties to control—** If any provision of the [indenture to be qualified](/usc/15/77ccc.md?p=9) limits, qualifies, or conflicts with the duties imposed by operation of [subsection (c)](#c) of this section, the imposed duties shall control.
- (b) **Additional provisions—** The [indenture to be qualified](/usc/15/77ccc.md?p=9) may contain, in addition to provisions specifically authorized under this subchapter to be included therein, any other provisions the inclusion of which is not in contravention of any provision of this subchapter.
- (c) **Provisions governing qualified indentures—** The provisions of [sections 77jjj](/usc/15/77jjj.md) to and including [77qqq](/usc/15/77qqq.md) of this title that impose duties on any [person](/usc/15/77b.md?p=a-2) (including provisions automatically deemed included in an [indenture](/usc/15/77ccc.md?p=7) unless the [indenture](/usc/15/77ccc.md?p=7) provides that such provisions are excluded) are a part of and govern every qualified [indenture](/usc/15/77ccc.md?p=7), whether or not physically contained therein, shall be deemed retroactively to govern each [indenture](/usc/15/77ccc.md?p=7) heretofore qualified, and prospectively to govern each [indenture](/usc/15/77ccc.md?p=7) hereafter qualified under this subchapter and shall be deemed retroactively to amend and supersede inconsistent provisions in each such [indenture](/usc/15/77ccc.md?p=7) heretofore qualified.
