(a) Prior law exclusively governs all suits, actions, prosecutions or proceedings which are pending or may be initiated on the basis of facts or circumstances occurring before the effective date of this chapter, except that no civil suit or action may be maintained to enforce any liability under prior law unless brought within any period of limitation which applied when the cause of action accrued and in any event within three years after the effective date of this chapter.

(b) All effective registrations under prior law, all administrative orders relating to such registrations, and all conditions imposed upon such registrations remain in effect so long as they would have remained in effect if this chapter had not been enacted. They are considered to have been filed, entered or imposed under this chapter, but are governed by prior law.

(c) Prior law applies in respect of any offer or sale made within one year after the effective date of this chapter pursuant to an offering begun in good faith before its effective date on the basis of an exemption available under prior law.

(d) Judicial review of all administrative orders as to which review proceedings have not been instituted by the effective date of this chapter are governed by section 411, except that no review proceeding may be instituted unless the petition is filed within any period of limitation which applied to a review proceeding when the order was entered and in any event within sixty days after the effective date of this chapter.
