11 U.S.C. § 1124: Impairment of claims or interests

leaves unaltered the legal, equitable, and contractual rights to which such claim or interest entitles the holder of such claim or interest; or cures any such default that occurred before or after the commencement of the case under this title, other than a default of a kind specified in section 365(b)(2) of this title or of a kind that section 365(b)(2) expressly does not require to be cured; reinstates the maturity of such claim or interest as such maturity existed before such default; compensates the holder of such claim or interest for any damages incurred as a result of any reasonable reliance by such holder on such contractual provision or such applicable law; if such claim or such interest arises from any failure to perform a nonmonetary obligation, other than a default arising from failure to operate a nonresidential real property lease subject to section 365(b)(1)(A), compensates the holder of such claim or such interest (other than the debtor or an insider) for any actual pecuniary loss incurred by such holder as a result of such failure; and does not otherwise alter the legal, equitable, or contractual rights to which such claim or interest entitles the holder of such claim or interest.
