   3. 3. This act applies to judicial proceedings concerning trusts commenced before its effective date unless the court finds that application of a particular provision of this act would substantially interfere with the effective conduct of the judicial proceedings or prejudice the rights of the parties, in which case the particular provision of this act does not apply and the superseded law applies;
   4. 4. Any rule of construction or presumption provided in this act applies to trust instruments executed before the effective date of this act unless there is a clear indication of a contrary intent in the terms of the trust; and
